INTRODUCTION
Stormwater Management Plan Overview
The North Carolina Division of Water Quality issued NPDES Phase II Permit NCS000406 to the City of
Wilmington effective February 1,2018. The Stormwater Management Plan is the City of Wilmington's
program to comply with NPDES Phase II permit NCS000406 for stormwater discharges from Small
Municipal Separate Storm Sewer Systems(MS4s). The plan defines strategies and guidelines necessary for
protecting water quality and reducing pollutant discharges to the maximum extent practicable. The plan also
includes reporting results for the current yearly reporting period from July 1,2021 to June 30,2022.
The plan is a guidance document to be used by the City staff and the general public. The plan is evolving
and will address needs and priorities that will be reflected in compliance programs over the 5 year
implementation schedule.
As required by EPA regulations for the NPDES Phase II stormwater programs,the following six minimum
measures are addressed in the plan:
1. Public Education and Outreach
2. Public Participation and Involvement
3. Illicit Discharge Detection and Elimination
4. Construction Site Runoff Control
5. Post-Construction Runoff Control
6. Pollution Prevention and Good Housekeeping for Municipal Operations
Program Implementation Status
The City of Wilmington is pleased to report excellent progress for year 4 compliance with requirements of
NPDES Phase II permit NCS000406. Primary areas of work include:
• Began inspection and maintenance of all city owned facilities with oil/water separators (18
locations).
• Continuation of Public Outreach and Public Participation efforts.
• Concentrated dry weather flow investigations in 2 impaired watersheds—Bradley Creek and
Hewletts Creek.
• Continued mapping updates of stormwater infrastructure in previous annexation area and
recent voluntary annexed area.
• Conducted Stormwater Control Measure(SCM) Inspection and Maintenance(I&M)training for
our Stormwater Field Crews.
• The Heal Our Waterways Program continued its forward momentum this year with several
collaborative grant projects,native plant outreach campaigns, and community events and
presentations.
1

In the last year and a half,the City's Stormwater Services initiated a review of its MS4 program to
achieve the following goals:
1. Prepare the City for the future DEQ audit and in understanding potential compliance issues(i.e.,
become"audit ready"),
2. Prepare for the re-permitting of the program and support development of what is needed for this
SWMP submittal,pursuant to the reformatted version by DEQ and new permit requirements, and
3. Identify areas where improvements can be made to enhance program implementation.
Using the information gathered during the review through site visits, interviews,and program
documentation,the City's consultant Moffatt&Nichol(M&N) developed a report that summarizes the
program elements (6Minimum Measures)and documents how the City is meeting its permit
requirements.
A series of recommendations were developed for each permit area to address any potential issues or
gaps with compliance as well as overall program enhancement and audit preparation. Each
recommendation is accompanied by an assessment of priority status,a qualitative assessment of budget
implications, and a recommended implementation schedule.
We continue to have success with our public outreach and participation program and education to the
public. The City remains focused on improving the water quality for the areas surrounding water bodies
as indicated by UNCW's Center for Marine Science annual contract for ambient monitoring of water
quality on creeks within the City.
CITY OF WILMINGTON STORMWATER SERVICES OVERVIEW
Comprehensive Stormwater Management
Comprehensive stormwater management takes into account both the quantity and quality of stormwater
runoff and is reflected in five core components of Wilmington's Stormwater Services program:
Management&Planning
Master planning utilizes the existing GIS stormwater system inventory to develop a long range plan to
improve drainage and water quality within an entire watershed. When planning on such a large scale,
Stormwater Services seeks involvement and input from citizens and stakeholders. Management
activities also include customer service—responding to customer concerns or inquiries and
administrative services required for operation of the City stormwater utility.
Regulatory and Enforcement
Regulatory and enforcement activities are outlined in the City's existing stormwater ordinance requiring
comprehensive stormwater management and creating technical standards for design and maintenance of
private stormwater facilities that are associated with new development. The Engineering Department
Stormwater review staff perform all stormwater management plan reviews and issues stormwater
discharge permits.
Stormwater Services,Public Services Department,provides annual inspections for privately permitted
2

stormwater retention/wet pond facilities. These inspections are performed in order to ensure compliance
with the approved operations and maintenance standards. Compliance with NPDES Phase II
stormwater regulations also fall into this category.
Capital Improvement Program(CIP)
The stormwater utility provides dedicated funding and staff resources for planning, designing, and
constructing capital improvement projects (CIP)and for performing routine maintenance and drainage
infrastructure inspections and rehabilitation. The CIP projects are necessary when the existing storm
drainage system is inadequate and can result in flooded streets,houses, and businesses. Capital
improvement projects require collaboration among City depaillnents, outside agencies, and citizens in
affected areas. Whenever feasible, capital improvement projects incorporate innovative design such as
stream restoration, green infrastructure, or stormwater control measures(SCM's)to improve water
quality and reduce the volume of stormwater runoff.A current CIP, Clear Run Branch, includes a grant
from the National Fish and Wildlife Foundation for funding assistance to re-establish a floodplain and
restore the stream for water quality and aquatic habitat benefits.
Operations and Maintenance
The City of Wilmington's Stormwater Services Division, Operations and Maintenance Section, is
responsible for maintaining the public drainage system. Maintenance activities are programmed in the
following sections: open drainage,closed drainage, street sweeping/pipe and inlet clearing, and
stormwater control measures (SCM's). The open drainage system consists of publicly accepted roadside
swales, man-made ditches and channels and naturally occurring creeks and ponds. The closed drainage
system consists of underground pipes, culverts, catch basins,manholes and related structures.
Both of these systems are maintained using manual and mechanical techniques to ensure that they
remain free of debris, sediment and scour for proper drainage. Street sweeping provides preventative
sweeping,vacuuming and other required maintenance to minimize the volume of gross solids; ie: trash,
litter, debris, sediment, and other pollutants entering the open or closed drainage systems. Pervious
pavement is also maintained by this section. SCM inspections and maintenance consists of activities
necessary to manage over 90 city-owned SCM facilities; including wet ponds, constructed wetlands,
bio-retention and infiltration facilities in functioning condition.As listed above, all O&M staff receive
training on water quality, SCM maintenance and other best practices such as riparian buffer
management.
Water Quality
Water quality monitoring is executed by the University of North Carolina at Wilmington under annual
contract with the City.Monitoring is performed on specific creeks and waterways within the City limits.
Monitoring tests for specific pollutants and resulting data is used to plan water quality improvements or
as a part of capital improvement projects, guide outreach and education efforts, assess water quality at
the sites monitored, identify persistent pollutant discharge areas or points,help to build a framework for
future detection and tracing of pollutant sources and obtain project-specific grant funding.
In addition, Stormwater Services implements an extensive Outreach, Education, and Public Involvement
3

program that serves the citizens of Wilmington. The program includes a wide array of water quality
education programming and materials. These programs include school presentations(using the
watershed model and other materials),homeowner association outreach,raingarden design and
installation, stormwater publications and giveaways, scheduled stream clean-up days,mass media
advertising, special event exhibits,workshops, storm drain marking, and collaborative efforts such as
grant projects with NC State University,UNC-Wilmington and other NGO's. Two ongoing/noteworthy
USEPA 319 grant projects are:
• Willard St. —wet pond to wetland retrofit (Jumping Run Branch).
• University Commons wet pond—retrofit to stormwater wetland(Clear Run Branch).
• Greenfield Lake Floating Wetlands (Squash Branch).
These efforts strive to improve water quality in the runoff entering waterbodies, educate and engage
citizens in protecting and improving local water quality through awareness, education,behavior
modification and action.

Regulatory and Enforcement
Public Services Code Enforcement
The City's stormwater ordinance required by this permit has been effective since November 1,2009.
Citizens can report suspected pollution through the Stormwater Hotline and the webpage reporting form.
All complaints received by the Stormwater Division either from the public or from City staff is investigated;
corrective action is prescribed; documented and followed until the violation is resolved.
A Enforcement/Civil Penalty Guidance tool has been developed and is now being used to ensure
consistency and help to guide the decision making process for NOVs and Civil Penalty issuance.Any
complaints received that have environmental impacts other than stormwater or fall outside the City's
regulatory authority are referred to DENR DWQ Wilmington Regional Office.
In an effort to maximize voluntary compliance,the City has,and will continue to develop and distribute
educational materials to targeted populations in an aggressive manner. Consequently, all complaints
provide the opportunity to educate the public on the issues that threaten stormwater,the best management
practices for prevention,the awareness of our city's stormwater program and the ordinance.
Compliance through Public Education
The stormwater code enforcement program goal is to maximize voluntary compliance through public
education and to use enforcement through penalties as a last resort. Staff has found that most stormwater
ordinance violations can be resolved through public education. Most of the people encountered violating the
ordinances are not even aware of their wrongdoings. Teaching them why they are in violation and why it
matters works because most people want to do the right thing. There are very few repeat offenders. In
Fiscal Year 2020-2021, a total of 3 repeat offenders were identified. Our enforcement and civil penalties are
reserved for; 1) serious discharges and spills with the potential of harming human health and the
environment,2)repeat offenders, and 3) as a last resort to achieve compliance.
The program developed an assortment of educational material for targeted audiences, as well as targeted
pollutants that teach the public about our stormwater ordinance and pollution prevention. For other
circumstance specific letters are written with instructions to guide violators to a solution and compliance
expectations. This clear outline of the City's expectations is a powerful tool for preventing future pollution
problems.
Yard Waste
Yard waste violations receive a face to face meeting(if possible) and a standardized letter explaining the
ordinance and the reasons why it is necessary. Also highlighted are the expectations for compliance and
civil penalties for any future violations. This letter is accompanied by a poster in English or Spanish and in
various sizes. The poster's objective is to help educate landscape companies and their employees on the
ordinance requirements that keep yard waste out of the drainage system and surface waters and the city's
expectations.
Pet Waste
Pet waste education and action is a significant focus for Stormwater Services. Reports of pet waste
violations receive a face to face meeting if possible. A brochure and flyer has been developed explaining
7

the dangers of pet waste bacteria in surface waters that includes the city's expectations of the ordinance and
penalty amounts for any violations. Pet waste message flags are used and distributed with ordinance
information at parks and public places, such as in specific neighborhoods in response to complaints. The pet
waste flyer is also available in a poster size for educating the public in parks and common areas. Pet waste
stations are planned and added each year in high pedestrian traffic areas as our budget allows.
Illicit Discharges
Reports of illicit discharges are addressed on a case by case basis. Informational posters and brochures for
general use have been developed for distribution and others for specific common source types. These
posters are distributed to specific types of businesses to display for employees in restaurants,vehicle
maintenance businesses, construction site on industry specific issues and best management practices to
avoid and prevent stormwater pollution.
Cape Fear Public Utility Authority
The Cape Fear Public Utility Authority(CFPUA)currently employs three Environmental Compliance
Officers, one Environmental Compliance Supervisor, and one Environmental Compliance Manager that
implement and enforce elements of the City's NPDES Wastewater Discharge Permit to include the City's
Collection System Permit. As part of those requirements the group regulates sanitary sewer overflows
(SSOs)and eliminates any wastewater or other polluted waters from leaving their system. They respond to
reports and investigate leads generated by the public or monitoring results as part of their permit
requirement and respond using public education, enforcement and maintenance. The CFPUA copies the City
on all SSOs and follows up with monitoring results and clean up measures. The CFPUA has maintained
right of entry on the properties that it services. The city and CFPUA are working together to keep open lines
of communication, continue to build relationships and combine resources in a continued effort to locate
chronic leaks and minimize release to MS4.
The CFPUA and the City continue to utilize the joint policy established in 2011 for the reporting and
documentation of SSOs and leaks. This policy provides procedures for CFPUA to follow regarding
reporting and documentation of SSOs the impact the City's MS4. These guidelines will enable the City to
comply with Phase II reporting requirements as well as provide assistance to CFPUA in mitigating any
potential threat to public health and environment. This policy is attached in Appendix D.

Water Quality
Monitoring Program Overview
In October 1997,the City of Wilmington contracted with the UNCW Center for Marine Science for a
project with the goal of assessing water quality in Wilmington City watersheds under base flow conditions.
Also, certain sites were analyzed for sediment heavy metals concentrations (EPA Priority Pollutants). New
Hanover County also participated in this effort for tidal creeks outside of City jurisdiction. UNCW
produced a combined report of results entitled Environmental Quality of Wilmington and New Hanover
County Watersheds. Immediately below is an overview of their work methods. Following this overview is
the executive summary of their most recent report.
The water quality data in these reports are presented from a watershed perspective. Some of the watersheds
cross political boundaries(i.e.parts of the same watershed may lie in the County but not the City). Howe
and Whiskey Creeks are examples. Water quality parameters analyzed in the tidal creeks include water
temperature,pH, dissolved oxygen, salinity/conductivity,turbidity,nitrate,ammonium, orthophosphate,
chlorophyll a, and in selected creeks fecal coliform bacteria. Similar analyses were carried out in the City
watersheds with the addition of total nitrogen(TKN),total nitrogen(TN),total phosphorus (TP),total
suspended solids(TSS)and biochemical oxygen demand(BOD) at selected sites.
Water Quality Methods
Field parameters were measured at each site using a YSI 6920 Multiparameter Water Quality Probe(sonde)
linked to a YSI 650 MDS display unit. Individual probes within the instruments measured water
temperature,pH, dissolved oxygen,turbidity, salinity, and conductivity. YSI Model 85 and 55 dissolved
oxygen meters were also used on occasion. The instruments were calibrated prior to each sampling trip to
ensure accurate measurements. The UNCW Aquatic Ecology laboratory is State-Certified for field
measurements(temperature, conductivity, dissolved oxygen and pH) and for laboratory chlorophyll a
measurements.
The analytical method used to measure chlorophyll a is described in Welschmeyer(1994) and US EPA
(1997). Chlorophyll a concentrations were determined from the 1.0 micrometer glass fiber filters used for
filtering samples for nitrate+nitrite and orthophosphate analyses. All filters were wrapped individually in
aluminum foil,placed in an airtight container and stored in a freezer. During the analytical process,the
glass filters were separately immersed in 10 ml of a 90%acetone solution. The acetone was allowed to
extract the chlorophyll from the material for 18-24 hours. The solution containing the extracted chlorophyll
was then analyzed for chlorophyll a concentration using a Turner AU-10 fluorometer. This method uses an
optimal combination of excitation and emission bandwidths that reduces errors in the acidification
technique.
Nutrients (nitrate,ammonium,total Kjeldahl nitrogen,total nitrogen, orthophosphate, and total phosphorus)
and total suspended solids (TSS)were analyzed by a state-certified contract laboratory using EPA and
APHA techniques. We also computed inorganic nitrogen to phosphorus molar ratios for relevant sites
(N/P). Fecal coliform concentrations were determined using a membrane filtration(mFC)method(APHA
1995).
12

For a large wet detention pond(Ann McCrary Pond on Burnt Mill Creek)and for a constructed wetland on
Kerr Avenue(at the headwaters area of Burnt Mill Creek)UNCW collected data from input(control)and
outfall stations. This data was used to test for statistically significant differences in pollutant concentrations
between pond input and output stations. The data were first tested for normality using the Shapiro-Wilk
test. Normally distributed data parameters were tested using the paired-difference t-test, and non-normally
distributed data parameters were tested using the Wilcoxon Signed Rank test. Statistical analyses were
conducted using SAS (Schlotzhauer and Littell 1987).

Executive Summary
This report represents results of Year 24 of the Wilmington Watersheds Project. Water quality data are
presented from a watershed perspective,regardless of political boundaries. The 2021 program involved
6 watersheds and 20 sampling stations. In this summary we first present brief water quality overviews
for each watershed from data collected between January and December 2021. As part of a change in
priorities, sampling at Barnards,Howe,Motts and Whiskey Creek were suspended for the time being to
emphasize upper Bradley Creek and the Greenfield Lake watershed,both of which are scheduled for
restoration measures; also two new sites in Barnards Creek upstream in Carriage Hills were sampled.
Barnards Creek—Barnards Creek drains into the Cape Fear River Estuary. It drains a 4,173 acre
watershed that consists of 22.3%impervious surface coverage, and a human population of
approximately 12,200. In October 2021 sampling was initiated at two upper creek sites near Carriage
Hills close to a wet detention pond(CHP-U and CHP-D). Early data show some potential dissolved
oxygen and fecal bacteria issues,but we caution that is only based on three samples.
Bradley Creek—Bradley Creek drains a watershed of 4,583 acres, including much of the UNCW
campus,into the Atlantic Intracoastal Waterway(AICW—Plate 1). The watershed contains about
27.8%impervious surface coverage,with a population of about 16,470. The uppermost site,BC-RD, is
on upper Clear Run at Racine Dr., and subsequently drains downstream to BC-CA,Clear Run at College
Acres. The two lower sites currently sampled are BC-NB,Bradley Creek north branch at Wrightsville
Ave.,and BC-SB, Bradley Creek south branch at Wrightsville Ave.). The sites were sampled six times
in 2021.
High turbidity and suspended solids in 2021 were not problematic. Dissolved oxygen was stressed(<5.0
mg/L)on most occasions at the two upper sites BC-RD and BC-CA.Nitrate and especially total
phosphorus concentrations were elevated in Clear Run compared with the lower two sites on
Wrightsville Avenue. Except for BC-RD, our Bradley Creek stations did not host significant algal
blooms during the 2021 sampling trips. Fecal coliform bacteria counts were moderate at the lower two
sites but particularly excessive at BC-RD and BC-CA,which had geometric mean counts of 823 and 750
CFU/100 mL,compared with the NC standard for safe waters of 200 CFU/100 mL.
Burnt Mill Creek—Burnt Mill Creek drains a 4,207 acre watershed with a population of about 23,700.
Its watershed is extensively urbanized(39.8%impervious surface coverage)and drains into Smith
Creek. Three locations were sampled during 2021,on six occasions. Fecal coliform conditions were
rated Poor in at the lowermost station BMC-PP at Princess Place and Fair in the upper two sites BMC-
AP 1 above and BMC-AP3 below Anne McCrary Pond,the regional wet detention pond on Randall
Parkway.Dissolved oxygen concentrations were Good in the two upper stations and Poor in the
remaining lower creek site.
We note that fecal coliform counts significantly declined during passage through the detention pond.
Several algal blooms occurred in the pond and one major bloom occurred at BMC-PP in May 2021.
Several water quality parameters showed an increase in pollutant levels along the creek from the outfall
16

from the detention pond to the downstream Princess Place sampling station, including fecal coliform
bacteria,nitrogen and phosphate,indicating non-point pollution sources continue to pollute the lower
creek.
Greenfield Lake—This lake drains a watershed of 2,465 acres,covered by about 37% impervious
surface area with a population of about 10,630. This urban lake has suffered from low dissolved
oxygen, algal blooms,periodic fish kills and high fecal bacteria counts over the years. The lake was
sampled at three tributary stream sites and three in-lake sites on 11 occasions. Of the tributaries of
Greenfield Lake, Squash Branch(GL-SQB,near Lake Branch Drive),Jumping Run Branch at 17th
Street and Jumping Run Branch at Lakeshore Dr.,GL-SQB suffered from low dissolved oxygen
problems, as did GL-2340 in the main lake.
Algal blooms are chronically problematic in Greenfield Lake and have occurred during all seasons. In
2021 a massive summer-fall blue-green algal bloom of Anabaena occurred. In August this organism,
combined with Microcystis aeruginosa produced measurable toxicity.Previously published studies
found a statistically significant relationship within the lake between chlorophyll a and five-day
biochemical oxygen demand(BODS)meaning that the algal blooms are an important cause of low
dissolved oxygen,and high BOD occurred congruent with the blooms in 2021. In 2021 all three
tributary stations exceeded the fecal coliform State standard on>45%of occasions sampled and rated
Poor;the in-lake stations were in Fair condition for fecal bacteria except for GL-2340,rated Poor.
Greenfield Lake is currently on the NC 303(d)list for impaired waters due to excessive algal blooms.
The thesis work of former UNCW graduate student Nick Iraola assessed the five main inflowing
tributaries to the lake to demonstrate that the largest inorganic nutrient loads came in from Jumping Run
Branch and Squash Branch. We are pleased to say that a coalition of stakeholders(the City, Cape Fear
River Watch,UNCW,NCSU and the engineering firm Moffat&Nichol)were awarded funds for 2020-
2022 and UNCW has been sampling in support of future nutrient reduction efforts on Jumping Run
Branch. Data show the Willard Street Wetland,between Willard St., 15th St. and 16th St. receives high
nutrient and very high fecal coliform loads from inflowing drains, and elevated concentrations of those
pollutants make it out of the wetland into Jumping Run Branch. An analysis of sediment phosphorus
loads found elevated concentrations in Jumping Run Branch both upstream and downstream of the golf
course. The engineering team is currently completing strategies to restore the wetland to reduce the
pollutant load, and the City is planning to take action on those strategies.
Hewletts Creek—Hewletts Creek drains a large(7,478 acre)watershed into the Atlantic Intracoastal
Waterway. This watershed has about 25.1%impervious surface coverage with a population of about
20,210. In 2021 the creek was sampled at four tidal sites on six occasions.
Only minor incidents of low dissolved oxygen occurred in Hewletts Creek in 2021. Turbidity was low
and did not exceed the state standard,and no major algal blooms occurred. Fecal coliform bacteria
counts were elevated somewhat at MB-PGR and NB- GLR,but no sites had a geometric mean that
exceeded 200 CFU/100 mL; and the geometric mean of fecal bacteria counts at HC-3 was not over the
state shellfishing standard.
Howe Creek—Howe Creek drains a 3,516 acre watershed into the ICW. This watershed hosts a
population of approximately 6,460 with about 21.4%impervious surface coverage. Due to resource re-
allocation,sampling was suspended here in 2020.
17

Motts Creek—Motts Creek drains a watershed of 3,342 acres into the Cape Fear River Estuary with a
population of about 9,530; impervious surface coverage 23.4%. Due to Covid-19 and resource re-
allocation, sampling was suspended here in 2020.
Smith Creek—Smith Creek drains into the lower Northeast Cape Fear River just upstream of where it
merges with the Cape Fear River(Plate 1). It has a watershed of 16,650 acres that has about 21.3%
impervious surface coverage,with a population of about 31,780. One estuarine site on Smith Creek,
SC-CH,was sampled by UNCW under the auspices of the Lower Cape Fear River Program(LCFRP).
The dissolved oxygen standard for Smith Creek,which is rated as C Sw waters,is 4.0 mg/L,which was
violated on only one of 8 occasions in our 2021 samples for a Fair rating. The North Carolina turbidity
standard for estuarine waters(25 NTU)was not exceeded. There were no major algal blooms present
in our 2021 sampling,although nitrate increased considerably over 2020. Fecal coliform bacterial
concentrations exceeded 200 CFU/100 mL on only one of 8 sampling occasions in 2021 for a Fair
rating.
Whiskey Creek—Whiskey Creek is the southernmost large tidal creek in New Hanover County that
drains into the AICW(Plate 1). It has a watershed of 2,078 acres, a population of about 8,000,and is
covered by approximately 25.1%impervious surface area. Due to resource re-allocation, sampling was
suspended here for 2021.
Water Quality Station Ratings—The UNC Wilmington Aquatic Ecology Laboratory utilizes a
quantitative system with four parameters (dissolved oxygen, chlorophyll a,turbidity,and fecal coliform
bacteria)to rate water quality at our sampling sites. If a site exceeds the North Carolina water quality
standard(see Appendix A)for a parameter less than 10%of the time sampled, it is rated Good; if it
exceeds the standard 10-25%of the time it is rated Fair, and if it exceeds the standard>25%of the time
it is rated Poor for that parameter.We applied these numerical standards to the water bodies described in
this report,based on 2021 data,and have designated each station as Good,Fair, and Poor accordingly.
Fecal coliform bacterial conditions for the entire Wilmington City and New Hanover County
Watersheds system(20 sites sampled for fecal coliforms)showed 10%to be in Good condition,45%in
Fair condition and 45%in Poor condition. Dissolved oxygen conditions(measured at the surface)
system-wide (20 sites) showed 40%of the sites were in Good condition, 30%were in Fair condition,
and 30%were in Poor condition. For algal bloom presence,measured as chlorophyll a, 65%of the 20
stations sampled were rated as Good, 20%as Fair and 15% as Poor. For turbidity, 100%of sites were
Good. It is important to note that the water bodies with the worst water quality in the system also have
the most developed watersheds with the highest impervious surface coverage;Burnt Mill Creek—39%
impervious coverage; Greenfield Lake—37%impervious coverage; Bradley Creek—28%impervious
coverage.

SECTION B: PUBLIC EDUCATION AND OUTREACH
1. Objectives for Public Education and Outreach
Distribute educational materials to the community or conduct equivalent outreach
activities addressing impacts of storm water discharges on water bodies and the steps the
public can take to reduce pollutants in storm water runoff.
2. BMPs for Public Education and Outreach
The permittee shall implement the following BMPs to meet the objectives of the Public Education
and Outreach Program and shall notify the Division prior to modification of any goals.
BMP Measurable Goals
a. Goals and Objectives Defined goals and objectives of the Local Public Education and
Outreach Program based on community wide issues.
b. Describe target pollutants The permittee shall maintain a description of the target
and/or stressors pollutants and/or stressors and likely sources.
c. Describe target audiences The permittee shall maintain a description of the target
audiences likely to have significant storm water impacts and
why they were selected.
d. Describe residential and The permittee shall describe issues, such as pollutants,likely
industrial/commercial issues sources of those pollutants,impacts, and the physical attributes
of stormwater runoff,in their education/outreach program.
Accomplishments:
A comprehensive public outreach/education and participation/involvement plan including goals, objectives,
target pollutants, sources,and target audiences is included in the Public Education&Outreach Appendix of
this report.
This plan defines the likely sources for each stormwater pollutant and includes suggested outreach messages,
formats, and strategies for reaching target audiences and for getting the public involved. Staff regularly
utilizes this information as a guide for planning,implementing, and evaluating outreach and participation
efforts throughout the city. Community-based social marketing is the crux of the plan. The plan is updated
and modified as pollutant sources,target audience demographics,public awareness,behavior,water quality,
funding, and other program variables change over time. The plan received an update in Winter 2022.
e. Informational Web Site The permittee shall promote and maintain, an internet web site
designed to convey the program's message.
Accomplishments:
Stormwater Services hosts a comprehensive website at www.wilmingtonnc.gov/stormwater.
Staff regularly updates the website with pertinent program content including stormwater news,monthly rain
barrel sale info,grant projects, Canines for Clean Water,Enviroscape,Annual UNCW Water Quality Report,
21

and a new webpage focused solely on stormwater capital and in-house drainage improvement projects.
This year,new resources for Trees, Cyanobacteria/Blue-Green Algae,as well as how to report an algal bloom
were added to the publications page of our website.New pet waste pollution videos created with WECT-
NBC-TV6 were also added to the website and updates were made to the Regulations/NPDES and major
projects.
In the near future,the City Communications Team will begin the lengthy process to update the city's web
presence to a new platform. Stormwater Services will be involved in this transition and upgrade,which will
require stormwater staff to re-create the stormwater webpages from scratch.
f. Distribute public education The permittee shall distribute stormwater educational material to
materials to identified target appropriate target groups (ex.: schools,homeowners, and/or
audiences and user groups. businesses). Instead of developing its own materials,the
permittee may rely on Public Education and Outreach materials
supplied by the state, and/or other entities through a cooperative
agreement, as available,when implementing its own program.
Accomplishments:
Stormwater content was incorporated into the city's booklet newsletter format in the spring. Content included
articles about the community pet waste survey,floating wetlands in Greenfield Lake, grant projects in
Bradley Creek watershed, stormwater outreach intern bio, and the UNCW water quality monitoring report of
creeks and lakes that fall within the city limits. State classification and rating data are also included in the
water quality report about each creek. The citywide newsletter was mailed to 45,000+city residents.
The Enviroscape Watershed Education Program has been integrated into the 8th grade curriculum since 2005.
The program reaches all 8th grade science classes in New Hanover County Schools each year. In FY21/22, 14
instructional videos were created in place of classroom presentations(due to the uncertainty of Covid19 at the
time). The videos were exceptional and sent to 21 teachers to use for their classrooms serving about 2,000
students in total.
Two major community events—LakeFest& StriperFest-were cancelled due to Covid19,however the annual
Earth Day Festival at Long Leaf Park returned and had the highest attendance and diversity ever. Stormwater
had an interactive`Be a Stormwater Hero"photo booth and also an educational table with displays,
giveaways,and educational information.
Education staff continued community pet waste cleanup promotion by posting the signs with free pet waste
roll bags in city parks. This program continues to be very successful distributing over 469 roll bags this year.
Stormwater compliance officers also responded to community complaints about pet waste.
Outreach staff presented to the Loblolly Garden Club in the spring. Topics covered included stormwater
pollution, solutions,the impacts of polluted runoff on area waterways, on-the-ground stormwater solutions,
and opportunities to get involved at the local level. A rain barrel was raffled off to one winner at the well-
attended event.
Wilmington continues to struggle with a bacterial pollution problem, in part due to uncollected pet waste.
Two new pet waste public service announcements—the Poop Fairy&Cheering the Scoop were filmed for
use on our Youtube Channel and in mass media campaigns.
This spring, coordinated mass media campaigns ran on Lamar Billboards,Port City Daily online newspaper,
and WECT digital,mobile, social media, and television platforms. Content was also included in Cape Fear's
Going Green Magazine and city social media outlets. In addition, a community pet waste survey was
implemented this spring. The timing of the survey was unfortunate due to the lateness of the citywide
22

newsletter being mailed, in which the survey was debuted. The survey was supposed to be out in the
community and completed before the spring pet waste ad campaigns ran.
g. Maintain Hotline/Help line The permittee shall promote and maintain a stormwater
hotline/helpline for the purpose of public education and outreach.
Accomplishments:
The Stormwater Pollution Prevention hotline and web reporting tool were established in January 2010 to field
calls from citizens,businesses, and employees to report illicit discharges and instances of potential or actual
stormwater pollution. The hotline phone#is 910-341-1020 and the web address is
www.wilmingtormc.gov/reportstormwaterpollution.
Hotline/web reports are routed to the Stormwater Code Compliance Officers who track,investigate,and
respond to each hotline report. Compliance officers routinely educate each violator, in addition to issuing
necessary fines and/or notices of violation. The hotline and online reporting webform are advertised in a
variety of ways including the website, City's cable TV channel, citywide newsletter, community events,
outreach promotional giveaways, and large educational magnets on stormwater maintenance and compliance
officer vehicles.
To summarize hotline/web reporting activity this past fiscal year:
17 calls were placed to the City's Stormwater hotline, 10 online webform reports were submitted,and 7 direct
emails and 8 direct calls were received by the Compliance Officers related to stormwater violations.
The nature of the hotline reports is found in the Enforcement section of the Appendix. In addition,there are
21 stormwater complaints recorded under the previous Compliance Officer that the method of notification is
unknown. The nature of the hotline reports are found in the Enforcement section of the Appendix.
h. Implement a Public Education The permittee's outreach program, including those elements
and Outreach Program. implemented locally or through a cooperative agreement, shall
include a combination of approaches designed to reach the target
audiences. For each media,event or activity,including those
elements implemented locally or through a cooperative
agreement the permittee shall estimate and record the extent of
exposure.
Accomplishments:
The extent of exposure requirement is documented in tables in the Public Outreach/Education Appendix, as
well as the Public Involvement Appendix. Documentation includes the date of event or activity,the type of
event/activity,audience reached,who delivered the content,the method of delivery and/or message, and the
resulting attendance or participation. In addition, agencies under contract with the city to help meet NPDES
deliverables are included in the Appendix.
Plans for Future Program Implementation
The city's stormwater outreach and education program continues to implement a variety of outreach and
educational events and programming. These activities educate and involve the community in stormwater
runoff pollution and solutions and inspire action and behavior change.
Covid-19 again impacted education programming and presentations at the start of the fiscal year,but
alternative measures were taken to provide community education, such as instructional videos and outdoor
events.
23

Plans for the next fiscal year include:
• Fecal coliform bacteria education—analyze data from the community pet waste survey.
• Create stormwater content for citywide spring newsletter booklet reaching 45,000 recipients.
• Conduct Enviroscape watershed education presentations for 8th grade science classes in New Hanover
County Schools—either in-person,virtually, or instructional videos,based on school requirements
this coming year.
• Implement new BMPs for public education for our new stormwater permit/SWMP.
24

SECTION C: PUBLIC INVOLVEMENT AND PARTICIPATION
1. Objectives for Public Involvement and Participation
Comply with State and local public notice requirements when implementing a public involvement
and participation program.
2. BMPs for Public Involvement and Participation
The permittee shall implement the following BMPs to meet the objectives of the Public
Involvement and Participation Program and shall notify the Division prior to modification of any
goals.
BMP Measurable Goals
-
a. Volunteer community The permittee shall include and promote volunteer opportunities
involvement program designed to promote ongoing citizen participation.
Accomplishments:
The City of Wilmington Stormwater Services contracts annually with Cape Fear River Watch(CFRW)and
New Hanover Soil&Water Conservation District(NHSWCD)to implement NPDES public involvement and
participation activities, as well as public education and outreach services.
Both agencies sign a multi-year contract with the City which specifies deliverables that help Stormwater
Services fulfill and/or enhance many of the requirements for NPDES public education and public participation.
In addition to full-time staff, each agency taps into a volunteer base and engages citizens to participate in
stormwater outreach/education and involvement/participation efforts.
Services performed by CFRW&NHSWCD include volunteer watershed clean-ups,volunteer creek
monitoring,volunteer storm drain marking, educational presentations for schools and the community,a
monthly rain barrel sale, creek eco-tours, school field days,website content,community stormwater best
management practice (BMP) installations, and more.
Each agency provides the City with four quarterly progress reports and invoices during the annual contract
period for the services performed. The cumulative year-end 4th quarter progress report for each agency is
included in the Public Involvement and Participation Appendix of this annual report. In addition,the city
regularly monitors agency/contract performance throughout the fiscal year.
b. Mechanism for Public The permittee shall provide and promote a mechanism for public
involvement involvement that provides for input on stormwater issues and the
stormwater program.
Accomplishments:
Additional stormwater capital projects and in-house projects were begun or continued this year and provided a
means for regular public input with stormwater staff. In addition,the stormwater projects page was updated
continually to provide the public with real-time information about projects that might impact them.
Public involvement in the form of public meetings, direct mail,public notices and/or one-on-one property
owner meetings were conducted for Clear Run Branch,Red Berry Drive,Whispering Pines,Park Avenue,
Greenville/White Avenue, Shandy Lane,Royal Palm Lane,Pirates Cove, and Wrightsville Green.
25

Community events,like the annual Earth Day Festival,also provide the community with a forum for directly
interacting with stormwater staff and getting questions answered on the spot.
Our hotline also provides the public a means to report on stormwater pollution in the community. See below.
c. Hotline/Help line The permittee shall promote and maintain a hotline/helpline for
the purpose of public involvement and participation.
Accomplishments:
The Stormwater Pollution Prevention hotline and web reporting tool were established in January 2010 to field
calls from citizens,businesses, and employees to report illicit discharges and instances of potential or actual
stormwater pollution. The hotline phone#is 910-341-1020 and the web address is

method of notification is unknown. The nature of the hotline reports are found in the Enforcement section of
the Appendix.
Plans for Future Program Implementation
The city's stormwater involvement and participation program engages community volunteers primarily through
contract agency activities. This year we have seen volunteer numbers increase with activities such as
watershed cleanups and creek monitoring. These activities involve the community in hands-on solutions and
inspire action and behavior change to improve area creeks and waterways. These activities can be viewed in the
Appendix in more detail.
Plans for the next fiscal year include:
• Negotiate and establish outside-agency contractual partnerships in alignment with our NPDES permit
term to engage the community in storm drain marking,creek monitoring,watershed cleanups, and
education.
• Continue to engage the community with mailers,public meetings, and one-on-one meetings for capital
and in-house projects
• Perform self-assessment of public outreach/education and involvement/participation BMPs and revise
PE/PI plan as necessary

SECTION D: ILLICIT DISCHARGE DETECTION AND ELIMINATION(IDDE)
1. Objectives for Illicit Discharge Detection and Elimination
a. Implement and enforce a program to detect and eliminate illicit discharges into the MS4.b.
Maintain a storm sewer system map, showing the location of all major outfalls and the
names and location of all waters of the United States that receive discharges from those
outfalls;
c. Prohibit,through ordinance, or other regulatory mechanism,non-storm water discharges
except as allowed in this permit and implement appropriate enforcement procedures and
actions;
d. Implement a plan to detect and address non-storm water discharges, including illegal
dumping,to the MS4;
e. Inform public employees,businesses, and the general public of hazards associated with
illegal discharges and improper disposal of waste; and
f. Address the categories of non-storm water discharges or flows(i.e., illicit discharges) in
Part I.H of this permit only if you identify them as significant contributors of pollutants to
the MS4.
2. BMPs for Illicit Discharge Detection and Elimination
The permittee shall implement the following BMPs to meet the objectives of the Illicit Discharge
Detection and Elimination Program and shall notify the Division prior to modification of any goals.
MP Measurable Goals
a. Maintain adequate legal authorities The permittee shall annually review the permittee's IDDE
ordinances or other regulatory mechanisms, or adopt any new
ordinances or other regulatory mechanisms that provide the
permittee with adequate legal authority to prohibit illicit
connections and discharges and enforce the approved IDDE
Program.
Accomplishments:
The City continues to utilize the existing ordinances in place to address illicit discharges to its system. The
City passed the Ordinance to amend Chapter 12 of the City Code on 9/15/2009 to address illicit discharges to
the stormwater system and to protect public water and sewer systems. This Ordinance change went into effect
on November 1,2009.
The current Cape Fear Public Utility Authority(CFPUA) ordinance defines wastewaters that are required to be
discharged into the sanitary sewer system. The City utilizes CFPUA's ordinance to address discharges of
regulated wastewaters to the City's MS4 and other natural outlets.
The City also utilizes a policy for reporting SSOs from the Cape Fear Public Utility Authority to the City(see
Appendix D). Citizens can also call CFPUA hotline for SSOs—https://www.cfpua.org/703/Water-Sewer-
Emergencies
The City will continue to review its ordinance annually to ensure we are providing adequate legal authority.
b. Maintain a Storm Sewer System The permittee shall maintain a current map showing major
Base Map of Major Outfalls. outfalls and receiving streams
The City continues to maintain and update a base map of major outfalls and receiving water bodies.
27

The City continues to make significant improvements and updates to the GIS inventory mapping of
stormwater systems using the best available data. At this time,percentages mapped are shown in below
figure of mapped areas with 97.5%of the City currently completed. This year,the City has continued to
re-map"Annex 95-98"areas to bring the data into our current mapping standards as these areas were
originally mapped in the early 2000s.Also,the River Lights(far southwest on map)will be fully mapped
when the development has been completed,which may take several more years as streets are slowly
turned over to the City. This development accounts for the remaining 2.5%that is unmapped. Thus, a
100%mapping completion may not take place for several more years.

c. Detect dry weather flows The permittee shall maintain a program for conducting dry
weather flow field observations in accordance with a written
procedure for detecting and removing the sources of illicit
discharges.
28

Accomplishments:
The City continues to use its data collection procedures established during the previous reporting years. Dry
weather flow procedures are included in Appendix D.
City Staff has a goal to conduct 25%of total identified outfall investigations in the City per year for dry
weather flow investigations. For this reporting year, staff conducted 27%. of total NPDES outfalls (Appendix
D). This was an increase from the previous reporting year. Staff concentrated investigations in 2 impaired
watersheds—Bradley Creek and Hewletts Creek. These two watersheds are important to the HOW program
for the City's volunteer watershed restoration plan.
d. Investigate sources of identified The permittee shall maintain and evaluate annually written
illicit discharges. procedures for conducting investigations of identified illicit
discharges.
Accomplishments:
The City has continued to utilize its existing ordinances and our Illicit Discharge Detection Elimination
(IDDE)Policy and Procedures Manual. The purpose of this document is to provide a standard for guidance
and information for the effective and efficient implementation of the Illicit Discharge Detection and
Elimination Program within the City of Wilmington. The document outlines the investigation,testing,
coordination with other authorities, GIS inventory, follow up, and documentation procedures to be taken to
resolve a questionable dry weather flow. The City plans to reevaluate the IDDE Manual in the Fall 2022 and
revise as necessary.
The City has completed its first full year of data input and documentation through the newly implemented
Munis, our data management systems. All details of incidences reported are entered from the start of an
incidence until the investigation is closed. This documentation into Munis has allowed for the extraction of
data for evaluation of our program,and assessment to identify repeat offenders and chronic violators as well as
serve as help us identify areas of the City with higher violation reports. See Appendix I.
e. Track and document investigations The permittee shall track all investigations and document the
illicit discharges date(s)the illicit discharge was observed; the results of the
investigation; any follow-up of the investigation; and the date
the investigation was closed.
Accomplishments:
The City continues to track illicit discharges in the stormwater system through our data management system.
All details of incidences reported are entered from the start of an incidence until the investigation is closed.
We continue reporting into the City's tracking database Munis(Appendix I).
f. Employee Training The permittee shall implement and document a training
program for appropriate municipal staff who as part of their
normal job responsibilities,may come into contact with or
otherwise observe an illicit discharge or illicit connection to
the storm sewer system.
Accomplishments:
The City did not conduct any IDDE training within this reporting year,however,training is tentatively
scheduled for winter 2022. The lack of training was a result of the vacant Compliance Officer position who
29

conducts the training. This position is currently being filled for the next reporting year.
g. Provide Public Education The permittee shall inform public employees,businesses, and
the general public of hazards associated with illegal discharges
and improper disposal of waste.
Accomplishments:
The Stormwater Watch newsletter, and the Enviroscape Watershed Education Program remain big
components of the City's efforts to educate the public on illegal discharges and improper disposal of waste.
Education staff continued community pet waste cleanup promotion by posting the signs with free pet waste
roll bags in city parks. In addition, several PSAs were completed. Two new pet waste public service
announcements—the Poop Fairy&Cheering the Scoop were filmed for use on our Youtube Channel and in
mass media campaigns.
For more outreach efforts conducted this year, see Section B.(f).
h. Public reporting mechanism The permittee shall promote,publicize, and facilitate a
reporting mechanism for the public and staff to report illicit
discharges and establish and implement citizen request
response procedures.
Accomplishments:
The Stormwater Pollution Prevention hotline and web reporting tool were established in January 2010 to field
calls from citizens,businesses, and employees to report illicit discharges and instances of potential or actual
stormwater pollution. The hotline phone#is 910-341-1020 and the web address is
www.wilmingtonnc.gov/reportstormwaterpollution.
See Section B.(g)
i. Enforcement The permittee shall implement a mechanism to track the
issuance of notices of violation and enforcement actions as
administered by the permittee. This mechanism shall include
the ability to identify chronic violators for initiation of actions
to reduce noncompliance.
Accomplishments:
The City of Wilmington uses Munis data management system to track all requests for service. This includes
illicit discharge reports from the public and from City staff. This system allows us to enter all relevant data
from an investigation and then analyze,map,and track various aspects of the incident including enforcement
actions and repeat offenders in order to identify chronic violators. For year 2021-2022,no civil penalties were
issued for illicit discharges. See Appendix I for enforcement actions summary for this reporting year.
Assessment of Program Implementation
The City continues to maintain and update a base map of major outfalls and receiving water bodies as well as
the stormwater inventory. In addition,the City will be continuously updating previous mapped areas that may
have changed due to recent drainage improvement projects or for updated mapping standards. The City will
continue with updating any stormwater mapping as necessary and report annually on the percent of changes.
30

Dry weather flow investigation's goal was fully met this year. Continue meeting set goal.
The City continues to utilize the Illicit Discharge Detection Elimination(IDDE)Policy and Procedures manual
as the program evolves and will evaluate repeat offenders as needed. The manual will be re-evaluated this year
and updated as necessary.
Employee training will be tentatively scheduled in fall 2022. The City has currently proposed in our draft
SWMP to conduct training for 5 divisions twice over the next permit term. These divisions would include
Stormwater field crews,Parks and Rec. field crews, Solid Waste field crews, Streets field crews and
Engineering Inspectors.
Enforcement of IDDE violations will continued to be tracked through the City's management system. The City
is currently in the process of filling the vacancy of the current Compliance Officer position that has been open
for the past year.
The City contracted with Moffat and Nichol to perform a program review of its NPDES Phase II program in
anticipation of our upcoming audit from the State in 2023. Moffatt&Nichol, as part of their scope of work,
completed their review of the IDDE program. Recommendations are identified as BMPs in the City's draft
SWMP provided to NC DEQ.
31

SECTION E: CONSTRUCTION SITE RUNOFF CONTROLS
The permittee relies on New Hanover County to comply with this minimum measure. The New Hanover
County Sediment and Erosion Control Program effectively meets the requirements of the Construction Site
Runoff Controls by permitting and controlling development activities disturbing one or more acres of land
surface and those activities less than one acre that are part of a larger common plan of development. This
program includes procedures for public input, sanctions to ensure compliance,requirements for construction
site operators to implement appropriate erosion and sediment control practices,review of site plans which
incorporates consideration of potential water quality impacts,and procedures for site inspection and
enforcement of control measures.
New Hanover County Erosion Control Program information supplied in Appendix E.
32

SECTION F: POST-CONSTRUCTION SITE RUNOFF CONTROLS
1. Objectives for Post-Construction Site Runoff Controls
a. Implement and enforce a program to address storm water runoff from new
development and redevelopment projects that disturb greater than or equal to one
acre,including projects less than one acre that are part of a larger common plan of
development or sale,that discharge into the small MS4. The program shall ensure
that controls are in place that would prevent or minimize water quality impacts.
b. Implement strategies which include a combination of structural Stormwater Control
Measures (SCM)and/or non-structural SCMs appropriate for the
community;
c. Use an ordinance or other regulatory mechanism to address post-construction runoff
from new development and redevelopment projects; and
d. Ensure adequate long-term inspection and maintenance of SCMs.
2. BMPs for Post-Construction Site Runoff Controls
The permittee shall implement the following BMPs to meet the objectives of the Post-
Construction Stormwater Management Program. To the extent there is any conflict
between this permit and the post-construction ordinances adopted by the permittee as
approved by the Division,the post-construction ordinances shall apply to permit
com.liance.
BMP Measurable Goals
a. Adequate legal authorities Maintain through ordinance, or other regulatory mechanism,
adequate legal authorities designed to meet the objectives of
the Post-Construction Site Runoff Controls Stormwater
Management program.
The permittee shall have the authority to review designs and
proposals for new development and redevelopment to
determine whether adequate stormwater control measures
will be installed, implemented, and maintained
The permittee shall have the authority to request information
such as stormwater plans,inspection reports,monitoring
results, and other information deemed necessary to evaluate
compliance with the Post-Construction Stormwater
Management Program.
The permittee shall have the authority to enter private
property for inspections at reasonable times any facilities,
equipment,practices,or operations related to stormwater
discharges to determine whether there is compliance the Post-
Construction Stormwater Management Program.
Accomplishments:
The City continues to utilize the Land Development Code that was amended and adopted on
September 15, 2009 to provide post construction controls in order to meet the requirements of
33

the City's NPDES Phase II permit and to bring the ordinance into compliance with the Coastal
Stormwater Legislation.
The City finalized draft updates to its Land Development Code in August 2021. Changes to
that Code went in effect in December 2021. A major change in the Code is applying higher SA
water quality standards to new development in the impaired Bradley Creek watershed. Changes
to the new code have now been in effect for the 2022 calendar year.
b. Strategies which include Maintain strategies that include a combination of structural
Stormwater Control Measures and/or non-structural SCMs implemented in concurrence
(SCMs) appropriate for the MS4 with(a)above. Provide a mechanism to require long-term
operation and maintenance of structural SCMs. Require
annual inspection reports of permitted structural SCMs
performed by a qualified professional.
A qualified professional means an individual trained and/or
certified in the design, operation,inspection and maintenance
aspects of the SCM's being inspected, for example, someone
trained and certified by NC State University for SCM
Inspection&Maintenance.
Within 12 months of the effective date of this permit,the
permittee shall evaluate, and revise as needed, SCM
requirements,to be at least as stringent as the minimum
requirements in 15A NCAC 02H .1000.
Accomplishments:
The DWQ SCM manual was adopted when the stormwater ordinance was amended in 2009.
This ordinance contains provisions addressing the use of combinations of structural and non-
structural SCM's to manage stormwater runoff. Some examples of these include providing
peak attenuation flow for the 2, 10 and 25 year storm event, requiring (new development) a 50
foot set back from surface waters, and stricter built-upon requirements for projects near SA
waters.
The City Engineering Dept. reviews new development plans for structural and non-structural
SCMs.
The Engineering Dept. employs four P.E.s for reviewing plans for new development and
conducting site inspections for compliance with the City's Stormwater Ordinance. Engineering
staff all are certified through the SCM Inspection and Maintenance Certificate offered through
NC State's Biological and Agricultural Engineering Department.
This reporting year, the Plan Review Engineers in the Engineering Dept. have been working on
code changes that will require annual reports of SCMs by a qualified professional. There are
options to meet this requirement that are still being discussed. The City will be reviewing
existing staff roles and responsibilities and making adjustments or recommendations to be
considered for the next budget year.
34

c. Plan reviews The permittee shall conduct site plan reviews of all new
development and redeveloped sites that disturb greater than
or equal to one acre(including sites that disturb less than one
acre that are part of a larger common plan of development or
sale). The site plan review shall address how the project
applicant meets the performance standards and how the
project will ensure long-term maintenance
Accomplishments:
The City continues to conduct site plan reviews utilizing the City's Land Development Code to
provide post construction controls to meet the requirements of the City's Phase II permit. A
summary of the plan review activities for this reporting year is available in Appendix F.
d. Inventory of projects with post- The permittee shall maintain an inventory of projects with
construction structural stormwater post-construction structural stormwater control measures
control measures installed and implemented at new development and
redeveloped sites, including both public and private sector
sites located within the permittee's corporate limits that are
covered by its post-construction ordinance requirements.
Accomplishments:
The City's Plan Review Engineers continue to update a spreadsheet of projects with
stormwater control measures installed during the reporting year. This spreadsheet includes the
dates permits were issued, review times for projects, types of projects (new development,
redevelopment), and the types and numbers of SCMs per project location. This spreadsheet will
continue to be used for future permits issued and evaluated or modified if data extraction is
warranted. See Appendix F.
The previous goal in the last reporting year was to incorporate a new software,EnerGov, to
help with the tracking of City issued stormwater permits. However, the software development
is still behind schedule so any partial progress made during the last reporting year had to be
reassessed. Currently while we wait on the software development, Engineering and Stormwater
staff are using the above spreadsheet information to merge into a GIS application so the City
can proceed with meeting this BMP until EnerGov can go live. Progress has been made with
GIS application and is approximately 30% complete. This GIS application will also help keep
track future permit renewals.
e. Deed Restrictions and Protective The permittee shall provide mechanisms such as recorded
Covenants deed restrictions and protective covenants that ensure
development activities will maintain the project consistent
with approved plans.
Accomplishments:
Current City of Wilmington stormwater management ordinance stipulates among other
requirements for stormwater management after construction that:
Record (as-built) drawings for all stormwater management facilities certified by an authorized
35

registered professional must be provided to the City for permanent record.
When deemed necessary by the City, access is granted through permit conditions allowing the
City and its agents and representatives adequate and perpetual access to the facility and
sufficient area for inspection.
The following excerpt from the new stormwater ordinance became operational upon adoption
City Council:
The approval of the stormwater permit shall require an enforceable restriction on property
usage that runs with the land, such as recorded deed restrictions or protective covenants, to
ensure that future development and redevelopment maintains the site consistent with the
approved project plans.
Additionally, the existing ordinance has provisions to ensure that conveyance of the property
does not terminate the original developer's obligations until a replacement permit has been
issued. The original developer will be required to record in the deed conveying the property a
notice of the existence of any stormwater devices and the purchaser's obligations to maintain
and inspect them and to obtain a permit. There are also specific and detailed special
requirements for property owner associations regarding operation and maintenance of
stormwater devices, escrowing funds to ensure maintenance and remedies for the City in the
event of failed compliance.
f. Provide a mechanism to require The permittee shall implement or require an inspection and
long-term inspection and maintenance plan for the long-term operation of the SCMs
maintenance of Stormwater Control required by the program. The inspection and maintenance
Measures(SCMs). plan shall require the owner of each SCM to perform and
maintain a record of annual inspections of each SCM.
Annual inspection of permitted structural SCMs shall be
performed by a qualified professional.
Accomplishments:
The DWQ SCM manual was adopted when the stormwater ordinance was amended in 2009.
This ordinance contains provisions addressing the use of combinations of structural and non-
structural SCMs to manage stormwater runoff. With this adoption, the City also reviews and
approves the I&M requirements and plans of the State through the review process. Inspection
and Maintenance plan schedules may vary with SCM type.
36

g. Inspections To ensure that all stormwater control measures are being
maintained pursuant to its maintenance agreement,the
permittee shall conduct and document inspections of each
project site covered under performance standards, at least one
time during the permit term.
Before issuing a certificate of occupancy or temporary
certificate of occupancy,the permittee shall conduct a post-
construction inspection to verify that the permittee's
performance standards have been met.
The permittee shall document and maintain records of
inspection findings and enforcement actions and make
them available for review by the permitting authority.
Accomplishments:
Under the current stormwater management ordinance of the City,permitees of structural SCMs
are required to properly maintain their stormwater management systems to ensure long term
operation. The City conducts annual compliance inspections for privately owned stormwater
SCM's in order to ensure maintenance responsibilities are being undertaken by property
owners. Inspections were conducted by a City staff member who has completed the Stormwater
SCM Inspection and Maintenance Certificate offered through NC State's Biological and
Agricultural Engineering Department (certification#182). Recertification occurred in March
2021.
For this reporting year, a total of 37 private sites were inspected for their respective SCMs with
15 sites being out of compliance (see Appendix F).
The City also conducts inspections of facilities during the development and construction
process. Before a Certificate of Occupancy is issued, compliance of permit conditions must be
present.
City Stormwater field staff, who work on the maintenance of City owned SCMs, received their
SCM Inspection and Maintenance certifications through NC State's program in November
2019. Approximately 5 staff members have certifications.
Stormwater Field Staff who conduct SCM maintenance on City owned devices went through
training for SCM Maintenance, Permits and Certifications on July 28, 2021. This training can
be found under the Pollution Prevention/Good Housekeeping section of this report
(SectionG.2.i).
h. Educational materials and training The permittee shall make available through paper or
for developers electronic means, ordinances,post-construction
requirements, design standards checklist,and other materials
appropriate for developers. New materials may be
developed by the permittee,or the permittee may use
materials adopted from other programs and adapted to the
permittee's new development and redevelopment program.
37

Accomplishments:
Currently all ordinances, design standards, application forms, SCM Manual and Technical
Standards for developers are found online at the City's website. The city provides instruction
online for the forms so that developers can provide the necessary documentation for the process
review.
i. Enforcement The permittee shall track the issuance of notices of violation
and enforcement actions. This mechanism shall include the
ability to identify chronic violators for initiation of actions to
reduce noncompliance.
Accomplishments:
The City has tracked the issuance of violations through its current inspection process since the
implementation of the stormwater ordinance. The City will continue to make improvements in
the inspection process (as necessary) and its associated database for private SCMs. The City
looks to identify repeat violators and work with owners of SCMs trough education for meeting
their permit requirements.
Assessment of Program Implementation
The City will continue to utilize the Land Development Code to provide post construction
controls to meet the requirements of the City's MS4 Phase II permit. Ordinances will be
evaluated annually to determine if modifications are needed. Recent modification went into
effect in December 2021.
Engineering Project Review Staff are working to provide a mechanism to track City issued
permits and renewals. This progress will continue into the next reporting year with the goal of
having a completed tracking tool.
City SCM Maintenance crews underwent training for better understanding of regulated
maintenance requirements, stormwater permit contents and SCM types.
The City will be evaluating staff position needs in next year's budget for the requirement of
SCM annual reports.

3. Post-construction Stormwater Runoff Controls for New
Development
a. To fulfill the post-construction minimum measure program requirement the
permittee may use the Department's model ordinance, design its own post-
construction practices that meet or exceed the rules found in 15A NCAC 02H
.1000, or develop its own comprehensive watershed plan that is determined by
the Department to meet the
post-construction stormwater management measure required by 40 Code of Federal
Regulations § 122.34(b)(5)(1 July 2003 Edition).
b. The permittee shall meet the requirements of the post-construction program for
construction projects that are performed by, or under contract for,the permittee. To
meet this requirement,the permittee may either develop the necessary requirements
for post-construction controls that will pertain to their own projects or develop
procedures to ensure that the permittee meets these requirements by complying with
another entity's Phase II Stormwater Management Programs for post-construction.
If the permittee decides to rely on another program for compliance with these
program areas for their own projects,they shall indicate in their Stormwater
Management Plan that the permittee will fully comply with the requirements of the
second party's post-construction programs.
c. Pursuant to 15A NCAC 02H .1017(9),to the extent allowable under State law,
additional requirements shall apply to projects draining to sensitive receiving
waters. For areas draining to Nutrient Sensitive Waters(NSW),where the
Department has approved a locally implemented NSW Stormwater Management
Program that addresses post-construction runoff,the provision of that program
fulfills the MS4 post-construction requirement.
d. The design volume of SCMs shall account for the runoff at build out from all
surfaces draining to the system. Drainage from off-site areas may be bypassed.
e. Pursuant to 15A NCAC 02H .1001(1)(c),to fulfill the post-construction minimum
measure requirement for linear transportation projects,including undertaken by an
entity other than North Carolina Department of Transportation(NCDOT), and are
projects constructed to NCDOT standards that will be conveyed to the State upon
completion,the permittee or regulated entity may use the Stormwater Best
Management Practices Toolbox(Version 2,April 2014),including any subsequent
amendments and editions, developed by the NCDOT. This NCDOT Stormwater
BMP Toolbox is available
at:https://connect.ncdot.gov/resources/hydro/Pages/Highway-Stormwater-
Program.aspx

SECTION G: POLLUTION PREVENTION AND GOOD HOUSEKEEPING FOR MUNICIPAL
OPERATIONS
1. Objective for Pollution Prevention and Good Housekeeping for Municipal Operations
a. Implement an operation and maintenance program that includes a training component and
has the goal of preventing or reducing pollutant runoff from municipal operations.
b. Provide employee training to prevent and reduce storm water pollution from activities
such as park and open space maintenance,fleet and building maintenance,new
construction and land disturbances, and storm water system maintenance.
2. BMPs for the Pollution Prevention and Good Housekeeping for Municipal
Operations
The permittee shall implement the following BMPs to meet the objectives of the Pollution
Prevention and Good Housekeeping Program and shall notify the Division prior to modification
of any goals.
BMP Measurable Goals
a. Inventory of municipally The permittee shall maintain, a current inventory of facilities and
owned or operated facilities operations owned and operated by the permittee with the potential
for generating polluted stormwater runoff. Also maintain a current
inventory of the MS4 system and municipally owned structural
SCMs.
Accomplishments:
The City currently keeps an updated inventory of known facilities with the potential for generating
polluted runoff. This list is updated and updates as necessary.
The City currently has a Spill Prevention Control and Countermeasure plan(SPCC) for the Operations
Complex and Police Headquarters and a separate Stormwater Pollution Prevention Plan(SPPP) for the
Fleet Maintenance building located within the complex. These are currently being reviewed for possible
updates.
The City has updated its list of all structural SCMs. These include permitted, non-permitted and grant
related SCMs. Currently,there are over 90.
The City maintains a GIS layer for its MS4 system and updates it annually as necessary.
b. Inspection and Maintenance The permittee shall maintain and implement, evaluate annually
(I&M) for municipally owned and update as necessary an Inspection and Maintenance (I&M)
or operated facilities program for municipal owned and operated facilities with the
potential for generating polluted stormwater runoff. The I&M
program shall specify the frequency of inspections and routine
maintenance requirements.
Accomplishments:
The City's consultant M&N has spent this past reporting year reviewing and making recommendations
40

for the I&M of city facilities in preparation for our upcoming audit by the NC DEQ. M&N has helped
the City to draft its SWMP for submission to the NC DEQ as required. The City will be conducting more
thorough I&M measures at all of its identified facilities as proposed in the draft SWMP. Currently,
inspections for our SPCC plan and SPPP are being conducted at the Police Headquarters,Fleet
Maintenance and Operations Complex.
The City awarded a maintenance contract with a local contractor in January 2021 for all our Oil/Water
separators. Due to budget constraints,the contract could not be executed until July 1, 2021. The City's
contractor conducted inspections and/or maintenance at 12 locations this reporting year. An additional 6
locations are currently being inspected for maintenance. These locations were delayed due to the
contractor having trouble finding their locations on site. After the completion of all the locations,the
City will have the contractor inspect and maintain the oil/water separators on an annual basis.
c. Spill Response Procedures The permittee shall have written spill response procedures for
municipally owned or operated facilities.
Accomplishments:
Spill Response procedures are identified in the City's SPCC plans for the Operations Complex and
Police Headquarters and also in the SPPP for Fleet Maintenance. The City will continue to follow these
plans and make any changes if necessary and ensure documentation is occurring within the plans.
The City has been working to develop written spill response procedures as recommended by M&N in the
City's Draft SWMP for the next reporting year.
The City will continue to review procedures with our Public Services Safety Specialist and also work to
improve and implement procedures and training.
d. Streets,roads,and public The permittee shall evaluate existing and new BMPs annually that
parking lots maintenance reduce polluted stormwater runoff from municipally-owned
streets,roads,and public parking lots within their corporate limits.
The permittee must evaluate the effectiveness of these SCMs
based on cost and the estimated quantity of pollutants removed.
Accomplishments:
The City currently utilizes BMPs that help reduce polluted stormwater runoff from streets,roads,and
public parking lots within its jurisdictional area. Stormwater crews sweep City streets with curbing(on
average)twice/month,NCDOT owned roads once/month, and City owned parking lots from once/month
to once/quarter. City owned parking lots include City operations facilities, City Hall,parks locations,
and recreation facilities.
In reporting year 2021-22, street sweepers swept 7,578 curb miles while collecting sediment,vegetation
and trash potentially diverted from the stormwater sewer system. The amount of debris volume collected
from Vacuum Trucks and Sweepers was 258.6 tons and 1512 tons,respectively.
In reporting year 2021-22, stormwater crews conducted hand maintenance of 127,721feet of ditch,22,569
linear feet of ditch by mechanical methods, cleaned 63,972 linear feet of pipe, and removed blockages and
cleaned 476 drainage inlets and manholes thus reducing debris, sediment,vegetation and trash potentially
diverted from being discharged into our receiving waters.
Street sweeping is conducted more frequently in the downtown central business areas to help minimize
the solids from entering the catch basins. Currently,the City conducts routine street sweeping in the
Central Business District,7 days/week to help prevent and reduce the amount of gross solids from
41

entering the downtown stormwater system.
The City continues to further look at all its field maintenance activities to determine if improvements to
water quality can be incorporated.
e. Inspection and Maintenance The permittee shall maintain and implement an I&M program for
(I&M) for municipally owned the stormwater sewer system including catch basins and
or maintained catch basins and conveyance systems that it owns and maintains.
conveyance systems
Accomplishments:
The City currently has a program for the inspection and maintenance of all City owned storm sewer
conveyance system. This program includes repair, inspection and maintenance of all City owned right of
ways and officially accepted easements. This information is included in this report under
Operations/Maintenance—Yearly Maintenance Activities Table.
f. Identify structural stormwater The permittee shall maintain a current inventory of municipally-
controls owned or operated structural stormwater controls installed for
compliance with the permittee's post-construction ordinance.
Accomplishments:
The City keeps and updates a SCM Manual for all its City owned SCMs. The manual includes all available
State DWQ stormwater permits, O&M plans, and site mapping to review maintenance requirements and
permit renewal dates along with any additional documentation that might be needed. This manual provides
information that can be readily reviewed by maintenance crews to keep the SCMs in compliance. This
manual is updated as needed when additional City facilities are constructed with permitted SCMs.
All City owned SCM are tracked for maintenance in Munis.

Management. applicators are followed. The permittee shall ensure municipal
employees, as appropriate based on job classification, are trained
and that applicable permits and certifications are maintained and
follow to the MEP measures for applicators.
Accomplishments:
The City has compiled all pesticide,herbicide and fertilizer application certifications for its Parks and
Recreation and Stormwater personnel to ensure that they are current. These certifications are updated and
renewed annually. Currently,there are 15 certifications for Parks and Recreation staff and 2
certifications for Stormwater/Public Services staff.
The City continues to minimize the use of glyphosate and others as an herbicide, especially in
aquatic environments, to help improve with water quality. The City purchased a specialty piece
of equipment(Conver) for mechanical invasive aquatic weed removal and has been using it with
good success of mechanical removal.
i. Staff training The permittee shall implement an employee training program for
municipal employees involved in implementing pollution
prevention and good housekeeping practices.
Accomplishments:
Three separate trainings related to PP/GH were conducted over this reporting year. These can be found
in Appendix G.
j. Prevent or Minimize The permittee shall describe and implement measures to prevent
Contamination of Stormwater or minimize contamination of the stormwater runoff from all areas
Runoff from all areas used for used for vehicle and equipment cleaning.
Vehicle and Equipment
Cleaning
Accomplishments:
Maintenance and cleaning conducted at the City's Operations Complex continues to occur at a covered
wash down station, located at the Solid Waste facility,equipped with an oil/water separator that accepts
wash water and directs it to the sanitary sewer.
In addition,all vehicle maintenance is conducted within the Fleet Maintenance Building. All interior
drains go directly to an oil/water separator and then to the sanitary sewer. As mentioned previously in this
section(2.b), all City owned oil/water separators are now under an annual maintenance contract for
inspection and cleaning. The City's SPPP for the Fleet Maint. Building addresses Good Housekeeping
within the facility. A site plan checklist is posted within the facility and the site manager conducts daily
inspections of the work areas.
Currently, all City Fire Stations have designated wash down areas for vehicle cleaning. The City
has been reviewing fire station locations this past year and will be recommending site visits to
ensure the facilities are working properly, education and SOPs (for locations lacking procedures)
as part of its draft SWMP.
43

Assessment of Program Implementation
The City will continue to keep and update an inventory of its known facilities with the potential for
generating polluted runoff an update as needed. Sites are identified by location,type of facility and
potential pollution sources. Inspection and Maintenance programs have been addressed in the City's
draft SWMP and will begin to be implemented in the next two years once approved by NC DEQ.
Continue annual contract with local consultant for oil/water separator inspection and maintenance at all
facilities that are applicable.
The City will continue to utilize SCMs that help reduce polluted stormwater runoff from streets,roads,and
public parking lots within its jurisdictional area. These SCMs will be evaluated annually to determine the
effectiveness by looking at the amount of debris removed from public streets and parking lots.
Develop or modify procedures to address the routine inspections of City owned SCMs in the next years as
outlined in the City's draft SWMP.
Continue Staff Training for PP/GH of municipal facilities and City owned SCMs as needed.
Review PP/GH programs,procedures, and recommendations for all City owned facilities with the potential
to pollute in preparation for NC DEQs upcoming NPDES audit. Address any changes outlined in draft
SWMP for PP/GH and begin implementing.

SECTION H: TOTAL MAXIMUM DAILY LOADS(TMDLs)
1. Objective
a. The permittee shall determine whether the MS4 discharges to receiving waters within a
TMDL watershed and identify the pollutant(s) of concern(POC). For all TMDLs with a
NPDES MS4 regulated WLA assigned to the permittee,the permittee shall determine
whether the POC have potential to occur in MS4 stormwater discharges.
b. The permittee will utilize BMPs within the six minimum measures to address the
permittee's assigned NPDES MS4 regulated stormwater waste load allocation (WLA)
identified in the approved TMDL to the maximum extent practicable and to the extent
authorized by law.
c. If subject to an approved TMDL with a NPDES MS4 regulated WLA assigned to the
permittee,the permittee will be considered in compliance with the TMDL if the permittee
complies with the conditions of this permit, including developing and implementing
appropriate BMPs within the six minimum measures to address the permittee's MS4s
NPDES regulated WLA to the maximum extent practicable(MEP). While improved
water quality is the expected outcome,the permittee's obligation is to implement BMP's
designed to address the NPDES regulated waste load allocation assigned to the permittee
to the maximum extent practicable(MEP). The permittee is not responsible for attaining
water quality standards(WQS). The Division expects attaining WQS will only be
achieved through reduction from all point and nonpoint source contributors identified in
the approved TMDL.
2. TMDL Plans
a. If the permittee has an existing TMDL Plan designed to address the NPDES MS4
regulated WLA assigned to the permittee,that includes monitoring to evaluate progress,
and which addresses the POC through the six minimum control measures; it satisfies the
objectives of this Section H.
b. The permittee may comply with a Department approved management strategy to address
an impairment or TMDL, such as a Nutrient Management Strategy,to satisfy the
objectives of this Section H.
c. The permittee may develop and submit,within 24 months,to the Department for
approval of an alternative approach, such as an Integrated Report-Category 4(b)
watershed plan,to satisfy the objectives of this Section H.
d. For new TMDLs that are not addressed by H.2. a,b, or c above, a TMDL Plan shall be
developed according to H.3 below, and submitted to the Division. Time periods shown
are from the later of the effective date of this permit or the TMDL as approved by EPA.

Bradley&Hewletts Creeks—Voluntary Watershed Restoration Plan Accomplishments:
The Bradley and Hewletts Creeks Watershed Restoration Plan has continued to make progress over the 2021-
2022 year in promoting volume-reducing best management practices(BMPs)to the public. The Heal Our
Waterways(HOW)Program,which is the informal name of the restoration plan implementation,heavily
influenced the demand for native plants in the area,helped incorporate greater representation for Bradley
Creek into City of Wilmington policies, and contributed to the installation of several volume-reduction
projects within the Bradley and Hewletts Creeks Watersheds.
As with previous years,two educational postcards were created and mailed, in the fall and spring,to 20,000+
residents and businesses within the Bradley and Hewletts Creek watersheds, as well as areas adjacent to the
watersheds that drain directly into the Intracoastal Waterway. The fall 2021 postcard welcomed oyster season
and made the connection between poor water quality and many of the closed shellfish harvesting beds in local
tidal creeks. The spring 2022 postcard featured various species of native plants that are readily available at
nurseries,easy to maintain,drought-tolerant, and work well in Stormwater Control Measures(SCMs), such as
rain gardens.
The native plant theme was also applied to all Fall 2021 media campaigns with WECT,Lamar billboards,and
National Public Radio affiliate,WHQR to coincide with the Native Plant Festival,held annually at the New
Hanover County Arboretum in mid-September.All the campaigns ran concurrently from September—
December 2022 and focused on how native plants can benefit local waterways. Several species were listed as
examples and highlighted benefits included: little to no need for fertilizers and pesticides; water conservation;
non-invasive tendencies; deeper root systems; and supporting local pollinators.
In addition to the Native Plant Campaign,the media partnership with WECT continued this year to raise more
awareness about the monthly rain barrel sale and the HOW Program. WECT.com is viewed by an average of
2.9 million unique visitors per month. The HOW Program was featured in several"Homepage Takeovers"on
WECT's website homepage to advertise the monthly rain barrel sale and the return of the Wilmington Earth
Day Festival.A new PSA was created for the Spring 2022 campaign to focus on the human connection to
water quality. Several staff members were used as actors and read a script discussing how they enjoy
waterways and how they can help protect them.
The native plant theme was also applied to the FY22 billboard campaigns for the HOW Program. The
billboard featured a close-up of purple coneflowers and other native flowers with the phrase,"Creek-Friendly
Yards... Plant Native Plants!"The billboard was posted next to a busy intersection near Bradley Creek to
reach watershed residents. The campaign had two runs, from October—November 2021 and April—May
2022.
HOW also renewed its presence as an underwriting partner with local National Public Radio affiliate,
WHQR. This year,the campaign included messaging about native plants and their benefits for water quality.
The messaging was broken into fall and spring campaigns. The first ran from September—December 2021
and included 47 total announcements. The second ran from March—May 2022 and included a total of 47
announcements. Each week,WHQR reached about 40,000 listeners in the Wilmington Designated Market
Area.
Several festivals returned to their in-person formats this year,including the Native Plant Festival,held at the
New Hanover County Arboretum in September 2021, and the Wilmington Earth Day Festival,held at Long
Leaf Park in April 2022. The HOW Program was present at both events and received significant attention
from attendees. Educational materials for the Native Plant Festival focused on the benefits of native plants for
48

water quality,including complex root systems,reducing the need for fertilizers and pesticides, and supporting
local pollinators. Attendees were able to learn more about stormwater runoff through the interactive
"Stormwater Plinko"game,and each player won an entry into the free rain barrel raffle. Stormwater Plinko
was also brought to the Wilmington Earth Day Festival, in addition to an interactive display that highlighted
solutions to common stormwater pollutants. 60-gallon rain barrels were raffled off at both events to winners
within the Bradley and Hewletts Creeks Watersheds.
The HOW Program maintained its online and social media presence. During FY22,the Heal Our Waterways
home page received 2,351 unique views. Updates were posted monthly and new native plant resources were
added to the Learning Library to support the outreach campaigns. The HOW Program's social media
presence continued to grow as well, as both the Facebook and Instagram accounts surpassed 450 followers. A
HOW-sponsored Instagram campaign also took place during the spring using a condensed version of the
watershed-wide mailer postcard which featured various species of native plants.
New this year,the HOW Program worked with North Carolina Coastal Federation and University of North
Carolina Wilmington to secure a 319 EPA Grant to continue stormwater improvements on campus. The grant
was awarded in January 2022. A new rain garden was installed in front of Leutze Hall as the first project to
help collect runoff from the roof and prevent it from entering Bradley Creek. The rain garden is estimated to
infiltrate approximately 1,900 cubic feet, or 14,213 gallons,of stormwater runoff.
The 319 Grant Partnership with North Carolina State University(NCSU) continued this year.NCSU is
currently working on monitoring within,and downstream of,two wet ponds that are currently slated for
retrofits. The HOW Program contributed mulch and cantilever sign frames for the future projects. A
bioretention area in front of a private apartment complex is projected to begin construction in late August,
with the constructed wetlands and impermeable baffle following shortly after. The grant is currently slated to
end in June 2023 but may request an extension due to unexpected delays in the construction process.
New Hanover Soil&Water Conservation District(NHSWCD)was once again granted a contract
(HOWBMP)with the city to install SCMs on private properties in the watersheds.HOWBMP produced 7
total installations this year and identified interested potential participants for next year. Of this year's
participants in the program,the homeowners were spread between Bradley and Hewletts Creeks and received
rain gardens and one backyard wetland. The total volume reduction from the HOWBMP program this year
was 326 cubic feet.
HOW Program staff continues to track SCM volume reduction projects that are in design or in the ground
using the GIS Atlas,which was reformed in FY 17-18. This tracking tool allows HOW to analyze current
impacts and assess stormwater volume reduction numbers from SCMs within the two target watersheds and
continues to be a key factor in HOW's progress,both in scope and accuracy. The GIS Atlas tool was a vital
component of calculating the volume reduction of several installations, including an infiltration cell placed in
a cul-de-sac, a bioretention area constructed by UNCW(separate from the grant projects), and private rain
gardens that were discovered during site visits. All these projects, and the data from reported SCMs from
partnerships such as the 319 grants,HOWBMP, and monthly rain barrel sales,were recorded for FY22.
Annual Assessment& Evaluation of Plan Implementation:
The HOW Program continued to influence action and see progress towards reducing the hydrographs for both
Bradley Creek and Hewletts Creek in FY22. There was heavy interest from the community in rain barrels and
native plants, and the HOW Program continued to support installations within the priority watersheds to treat
and manage stormwater runoff.
49

The Bradley Creek Watershed has several ongoing grant and large-scale CIP projects that saw progress this
past fiscal year. The HOW Program collaborated with internal partners and external partners, such as the
North Carolina Coastal Federation,North Carolina State University Biological Systems Engineering and
Cooperative Extension,University of North Carolina Wilmington,to install large green infrastructure projects
and prepare for continued installations in the coming fiscal year. This helped reach 95%of the 0.15 acre feet
internal measure set for the Bradley Creek Watershed.
While the Hewletts Creek Watershed did not have as many large-scale projects,there were 32 smaller
installations that included residential rain gardens,rain barrels, and tree plantings. The HOW Program
partnered with New Hanover Soil&Water Conservation District, local stakeholders,the Wilmington
Farmer's Market, and internal partners to achieve these goals. There were record rain barrel sales this year,
which largely contributed to the number of projects within the Hewletts Creek Watershed. The Wade
Wetland and past grant-funded SCM installations continue to function well and contribute to improved water
quality. Bacteria levels were lower in Hewletts Creek this year,with one tidal station even meeting the State
standard for safe shellfish harvest.
2022 marks the 10th anniversary of the adoption of the Bradley and Hewletts Creeks Watershed Restoration
Plan. The HOW Program has grown significantly since the plan was first adopted and has seen progress
towards reducing the hydrographs for both creeks. Over the years, 698,557 cubic feet and 59,622 cubic feet
have been diverted from Hewletts Creek and Bradley Creek,respectively. Combined,this equals
approximately 5,671,573 gallons of stormwater runoff per each 1-year,24-hour storm. This is a significant
achievement and highlights the importance of having the Watershed Restoration Plan in place. It was fitting
that the HOW Program was also recognized by the Lower Cape Fear Stewardship Development Coalition
with the"Stewardship Champion"award this year to help celebrate its 10th anniversary and successes.
Since the plan was officially adopted in 2012,there have been significant strides towards reaching the
hydrograph reduction goals within the plan. The first benchmark is based on reducing the 2010 baseline
hydrographs to the 2006 hydrographs. The 2006 hydrograph goal for Bradley Creek is to reduce the
hydrograph from 14,096,887 cubic feet to 13,238,755 cubic feet. The 2006 hydrograph goal for Hewletts
Creek is to reduce the hydrograph from 21,241,163 cubic feet to 19,901,257 cubic feet. So far,the total
volume reduction is 59,614 cubic feet(6.9%of goal achieved) for Bradley Creek and 698,564 cubic feet
(52%of goal achieved) for Hewletts Creek.
Ultimately,the HOW Program is continuing in its progress towards the Bradley and Hewletts Creeks
Watershed Restoration Plan's 6 Objectives and 35 Actions. The information below outlines that progress
towards the Objectives&Actions of the Bradley&Hewletts Creeks Watershed Restoration Plan.

In support of Actions 1-1, 1-2, and 1-5,the HOW program continued to submit comments on site plans and
participate in the Technical Review Committee(TRC)process to promote green infrastructure practices to
private developers. The updated Land Development Code was officially approved in August 2021 and went
into effect on December Pt,2021. The updated Land Development Code includes the change applying SA
waters standards to Bradley Creek for post-development stormwater requirements. The HOW Program was
invited to continue in the review process with the next step of reviewing the technical standards for
development. The stormwater technical standards went through an initial round of comments in May, and
additional chapters will be released for review in the coming months,including streets, sidewalks,
landscaping,etc.
HOW continued the fall and spring watershed mailers again this year in support of Action 1-4,with a greater
focus on actions and impact. The fall mailer announced the start of oyster harvesting season and how
stormwater runoff can influence the status of shellfish harvesting areas. Actions to prevent bacterial pollution
were also included, supporting Action 1-2. The spring mailer focused on the benefits of native plants and
included specific species and resources that property owners could use while planning their landscaping. Both
postcards were mailed to over 20,000 residents within the target watersheds.
To also support Actions 1-2 and 1-4, all media partnerships with WECT,WHQR, and Lamar Billboards
continued this year to educate residents on the benefits of native plants. The HOW website and all social
media channels(FB, Twitter, &IG)continued to remain active throughout the year as well. The HOW
Program also maintained its online newsletter, sending quarterly updates on topics such as the history of
Hewletts Creek, grant updates,and more. There are currently 449 active Constant Contact newsletter
subscribers.
Regarding Action 1-3, CCAP is a funding program that is coordinated through the New Hanover Soil and
Water Conservation District(NHSWCD). Information about this program was shared with property owners
within the Bradley and Hewletts Creeks Watershed areas. However,this was not a large area of focus this
fiscal year as most projects were either in-house, installed through HOWBMP,or were funded by 319 grants.
The HOW Program also continued to promote LID through existing educational programs, such as the
monthly visits to the Wilmington Farmer's Market,website materials, and visits to annual events. The Native
Plant Festival and Wilmington Earth Day Festival were widely attended events this fiscal year and the HOW
Program brought materials discussing"Stormwater Solutions"that property owners could easily incorporate.
The HOW Program also presented again for NCSU Cooperative Extension's online"Backyard
Sustainability" series.

In accordance with Action 2-1,Dr. Mike Mallin's office with the University of North Carolina at Wilmington
(UNCW)continues to conduct regular surface water sampling to determine what effects the program's
volume reduction efforts are having on the health of the creeks.North Carolina State University is also
currently monitoring stations within several wet ponds in the Bradley Creek Watershed that will be
undergoing retrofits as part of the collaborative 319 Grant project.
This plan objective concentrates heavily on the classification of local waters and the appropriateness of
current classifications considering today's conditions,but as with previous years,there was not much activity
towards pursuing reclassification. Previous discussions with representatives from North Carolina Department
of Environmental Quality(NCDEQ) indicated that reclassification of certain waterbodies would not be
supported. This objective will be undergoing review in the coming fiscal year to establish goals that are
achievable and more reflective of the current conditions of the State classification system.

Both Action 3-1 and Action 3-2 saw continued progress. This was accomplished through grants,inter-
depaitliiental partnerships, local rain barrel sales,and the HOWBMP contract program.
The North Carolina Coastal Federation's (NCCF)319 grant for stormwater retrofits on UNCW's campus was
a major contributor towards reducing the hydrograph of the Bradley Creek Watershed.A rain garden was
installed in front of Leutze Hall in June 2022 and will treat approximately 14,213 gallons during each 24-hour
storm. Additionally,UNCW pursued a bioretention project near DeLoach Hall that tied into an outdoor
geology exhibit. The DeLoach Hall bioretention project is estimated to treat approximately 16,203 gallons of
stormwater runoff during each 24-hour storm. The UNCW projects, in addition to the other projects
completed within the Bradley Creek Watershed,helped achieve 95%of the internal volume reduction goal of
0.15 ac. ft. for the Bradley Creek Watershed.
The HOWBMP contract with New Hanover Soil and Water Conservation District installed several residential
SCMs in both the Bradley and Hewletts Creek Watersheds this year. There were 6 total rain gardens and 1
backyard wetland between 7 homeowners with a total volume reduction of 326 cubic feet.
Rain barrels installations also continued at a high rate in the Bradley and Hewletts Creek Watersheds.
Demand was at its highest this year,with rain barrels frequently selling out during the monthly rain barrel
sale largely due to increased awareness of the program and supply chain interruptions. Social media
campaigns run by the HOW Program and New Hanover Soil and Water Conservation District helped to push
out more messaging about the rain barrel sale, and the monthly sale and giveaways hosted by the HOW
Program contributed to the large distribution of rain barrels in FY22.
The HOW Program also set aside funds for contracted tree plantings this fiscal year. A total of 45 trees were
planted in and near existing SCMs within both the Bradley Creek and Hewletts Creek Watersheds and within
a drainage easement in the Wrightsville Green neighborhood.All trees are under an 18-month warranty by
the contractor and will be replaced if needed.

During FY22,the GIS Atlas continued to be an important tracking tool for the projects installed within the
Bradley Creek and Hewletts Creek Watersheds. The GIS Atlas data is useful for creating trends over time and
for justifying potential changes to the internal goals for volume reduction. The Hewletts Creek internal
performance goal,for example, is currently under review to determine the level of volume reduction that
would be most achievable annually,using the historical volume reduction data of projects installed in the
watershed each year.
The HOW Program continued to promote LID retrofits on private properties through the TRC Review
process,and on public properties as opportunities arose in support of Actions 4-3 and 4-7. An infiltration cell
was incorporated into a street and drainage improvement project on Renee Court in the Bradley Creek
Watershed. Using the GIS Atlas(Action 4-1),the infiltration cell is expected to infiltrate 1,937 cubic feet
(14,488 gallons)of runoff from the cul-de-sac and a portion of Renee Court. The street historically
experienced flooding,which will also be alleviated through this project.
This year,the HOW Program in collaboration with the Wrightsville Green CIP project,pursued a tree
planting contract to install 45 within the Bradley Creek and Hewletts Creek Watersheds in support of Action
4-4. This was done using funds that were newly established specifically for stormwater tree planting projects
and the Wrightsville Green CIP budget. Only native tree species were planted, such as live oaks,bald cypress,
longleaf pines, and more.

Partnering with local stakeholders continues to be one of the greatest avenues for project implementation and
education. To achieve Action 5-1,the HOW Program renewed partnerships with local news outlets(WECT,
WHQR, and Lamar Billboards),the Wilmington Farmer's Market,the Wilmington Earth Day Alliance, and
the NC State University(NCSU) Cooperative Extension Office to spread messaging related to green
infrastructure and native plants through social media and local events.
The HOW Program continued to interact with local stakeholders by bringing a monthly display to the
Wilmington Farmer's Market, and attending restored in-person events such as the Native Plant Festival and
the Wilmington Earth Day Festival. The festivals were highly attended and great outreach opportunities for
the HOW Program,where many attendees signed up for the online newsletter and engaged with the
interactive displays. The local NCSU Cooperative Extension Office also invited the HOW Program to present
for the stormwater-specific presentation in its"Backyard Sustainability Series",which was a virtual training
for residents in the area to discuss stormwater runoff and solutions.
The HOW Program's partnerships with North Carolina Coastal Federation and staff and professors at UNCW
helped push forward stormwater retrofits on UNCW's campus. A second 319 grant was awarded in January
2022 to help install bioretention and pervious pavement projects throughout campus. One rain garden was
installed in front of Leutze Hall in June 2022 and several pervious pavement projects are planned for next
fiscal year,in and near the older section of campus.UNCW staff and professors have also worked to install
some projects on their own,including a small section of pervious pavement while resurfacing a parking lot, a
bioretention area near DeLoach Hall,and a solar-powered pump for a cistern previously provided by the
HOW Program.
Internally,the HOW Program was introduced to the City's Engineering group on a relevant Multi-Use Path
(MUP)project within the Bradley Creek Watershed. While the project is on a tight schedule and budget,the
engineers of the project still met with the HOW Program to discuss ways to preserve more trees and potential
locations for green infrastructure that could be incorporated post-construction to help mitigate runoff coming
from the MUP.
Objective 6: Measure success and adapt plan based upon results:

and modify plan as needed WB,UNCW
The GIS Atlas continues to be a vital tool for monitoring progress towards the volume reduction goals within
the Bradley and Hewletts Creeks Watershed Restoration Plan, in accordance with Action 6-1. 16 projects
were installed in the Bradley Creek Watershed for a total of 6,216.52 cubic feet of volume reduction,
reaching 95%of the internal measure within the City's Strategic Plan. In the Hewletts Creek Watershed,there
were 32 total projects for a total of 459.46 cubic feet of volume reduction. There was a record number of rain
barrels sold this year through the monthly rain barrel sale, several of which went to owners within the
Hewletts Creek Watershed. There were several tree plantings and residential rain gardens as well. However,
these practices are smaller in nature and do not provide as large a volume reduction as the larger grant
projects happening along Bradley Creek. The educational benefits of these projects,however, is still worth
reporting.
UNCW continues to monitor both creeks for bacteria,dissolved oxygen,turbidity, and other water quality
parameters. Four established stations were monitored for both Bradley Creek and Hewletts Creek, all of
which were sampled six times throughout the year. Bradley Creek did not have many problems with turbidity
and sediment pollution,but there were high counts of fecal coliform bacteria in the upper reaches of the creek
and moderate counts at the tidal stations near the mouth of the creek. The upper reaches of the creek have
notoriously seen high bacteria levels, and there are several grant and CIP projects in action to improve water
quality in the creek. Hewletts Creek, on the other hand, saw improvements in bacteria levels. Only one station
had one occurrence of high fecal coliform bacteria. The other stations were low, and the geometric mean at
the mouth of the creek was lower than the State standard for safe shellfish harvest(14 CFU/100 mL). If the
trend continues,the HOW Program may pursue a more dedicated monitoring study for the purpose of
removing the shellfish impairment for portions of Hewletts Creek.
Staff this year also performed an internal review of the progress of the HOW Program and the actions within
the Watershed Restoration Plan, supporting Action 6-3. Projects, funding, and partnerships continue to
successfully reduce the hydrographs for both creeks and raise awareness about the HOW Program. There are
a few actions that need to be updated to reflect changes in regulations and updates from the State and other
changes, so staff will be coordinating with the original stakeholders that helped create the plan in the coming
fiscal year. The group will discuss potential changes to keep the Watershed Restoration Plan as relevant as
possible to the current climate and continue its successful influence within the community.

Plan Overview
Stormwater runoff is water from rain or irrigation that flows over land and into local creeks,
streams and waterways. According to the US Environmental Protection Agency (EPA),
stormwater runoff is the #1 source of surface water pollution.
Impervious surfaces are hard surfaces that rainwater cannot penetrate or naturally absorb, such as
driveways, streets,parking lots and rooftops. Instead, runoff flows over these surfaces picking up
pollutants such as pet waste bacteria, auto fluids, fertilizers,pesticides, litter, and yard debris and
carries them through the stormwater drainage system, directly into area waterways.
In Wilmington, stormwater runoff travels through a complex, interconnected system of storm
drains,pipes, ditches, creeks, and other natural and man-made features. In Wilmington, the storm
drainage system consists of approximately:
• 18,508 storm drains, manholes, and other structures
• 312 miles of pipes/culverts
• 218 miles of open drainage (ditches and channels)
• 46 acres of retention ponds, infiltration basins, and lakes including Randall Pond, Silver
Stream Pond, and Greenfield Lake
• 131 acres of stormwater BMPs such as Kerr Avenue Wetland, Park Avenue Bioretention
Area, Wade Wetland, Silver Stream Pond, Independence Pond, the Stormwater
Demonstration Site in Anne McCrary Park, etc.
This plan for Public Outreach/Education and Public Involvement/Participation is a component of
the City of Wilmington's Stormwater Management Plan(hereinafter referred to as Stormwater
Plan), as required by the State of North Carolina Department of Environment and Natural
Resources Division of Water Quality Permit No. NCS000406. This federal stormwater permit
authorizes the City of Wilmington to discharge stormwater from a municipal separate storm sewer
system(MS4) to the receiving waters of the State within the Cape Fear River and White Oak
River Basins,under Environmental Protection Agency's National Pollutant Discharge Elimination
System(NPDES) Program.
As required by the NPDES Permit, the City of Wilmington's Stormwater Plan must detail the
City's outreach and participation program for the five-year term of the stormwater permit. This
document serves as the official Public Outreach/Education and Public Involvement/Participation
Plan.
Public education and participation are essential tools to develop awareness, stewardship, and
behavior change for stormwater pollution issues within the City of Wilmington. By successfully
reaching out, creating awareness, and engaging citizens and businesses, we can reduce the impact
of stormwater pollution on our local surface waters,preserving them as a healthy and vital
resource for the Wilmington- area.
Since 1993, scientists at the UNC Wilmington Center for Marine Science Research have been
assessing the water quality of Wilmington's major creeks and waterways within the city limits.
Approximately 22 sampling sites assess the water quality of ten of Wilmington's creeks, as well as
72

Greenfield Lake, and the Cape Fear River. The findings are reported annually and serve as a
valuable tool to gauge changes in local water quality and guide our outreach/education and
involvement/participation efforts.
In addition, the City of Wilmington has established long-standing contractual relationships with
Cape Fear River Watch &New Hanover Soil &Water Conservation District, which enables us to
robustly satisfy our outreach/education and participation/involvement BMPs and program
goals/objectives.
It is important to note that this plan is a working document; therefore the goals, objectives,
pollutants, and target pollutants will change over time based on a variety of factors including
audience awareness,behavior trends, local water quality data, observational data, etc.
73

Program Goals & Objectives
Goals:
The City of Wilmington Stormwater Services implements a Public Education/Outreach and
Involvement/Participation Program based on community-wide issues with the overarching goals
to:
• Raise awareness and educate the community about the impacts of polluted stormwater
runoff on local waterways, including simple and attainable solutions to stormwater
pollution
• Promote ongoing citizen participation by involving the public in community activities
aimed at reducing and preventing stormwater pollution.
These goals inform, educate, and involve the public so they can make informed decisions and take
responsibility for preventing polluted runoff from impacting area waterways.
As mentioned previously, the City of Wilmington has established long-standing contractual
relationships with two outside agencies which enables us to further engage and involve the public
in stormwater education and experiences.
Public Outreach/Education Objectives:
o Distribute educational handouts,publications, and digital and mobile materials to educate
the public and increase awareness about stormwater pollution, environmental impacts, and
solutions.
o Educate school children with established watershed education curriculum.
o Participate in community events to engage and educate the public about stormwater runoff.
o Include stormwater content in the citywide newsletter reaching approximately 44,000
residents and businesses.
o Develop mass media and social media campaigns to increase awareness of stormwater
pollution, water quality, and solutions for the general public.
o Maintain a robust stormwater website featuring educational content and ways for the
public to get involved in stormwater stewardship.
Public Participation/Involvement Objectives:
o Include the public in the development, implementation and review of the stormwater
management plan.
o Develop and promote interactive, hands-on programs that engage citizens in stormwater
stewardship and promote stormwater-friendly behaviors. These programs may be
contracted with outside agencies.
o Maintain a robust stormwater website featuring educational content and ways for the
public to get involved in stormwater stewardship.
o Promote the Stormwater Pollution Prevention Hotline and website form for the public to
report instances of stormwater pollution
74

o Promote a mechanism for public involvement for citizens to provide input on stormwater
issues and the stormwater program. Currently, citizens are notified and asked for input
with in-house and capital improvement projects, which are often large-scale in scope.
Public meetings, one-on-one meetings, public mailings/doorhangers are one method of
promoting public input. Citizens can also always call our main stormwater number to ask
questions or provide feedback.
In addition, our program utilizes the following concepts as a basis for outreach/education
efforts and public involvement/participation programming:
• Social marketing (not to be confused with social media) is the backbone of outreach/education
programming. Social marketing involves using commercial marketing principles and
techniques to improve society by changing behaviors. Smokey the Bear and This is Your
Brain on Drugs, are well-known examples of nationwide social marketing campaigns.
• Awareness is the first step towards behavior change.
• Education involves audiences who are aware of the issues and can be given more in-depth
information to make informed decisions in their daily lives that positively impact stormwater.
More detailed education results in further behavior change.
• Our waterways are important for many reasons including quality of life, tourism, the economy,
recreation, aquatic habitat for many species, nurseries for seafood, to sustain life, etc.
• Polluted stormwater runoff flows directly into local waterways where it impacts water quality,
aquatic habitat, shellfish harvesting, recreational water activities and access, etc.
• Storm drains and drainage conveyances (i.e. swales, ditches,pipes, etc.) carry stormwater
directly to local waterways without any treatment. Only rain should go down the storm drain.
• Impervious surfaces increase the speed and volume of polluted stormwater runoff entering the
stormwater drainage system and flowing into waterways.
• More impervious surfaces =more degraded water quality.
• The quality and amount of polluted stormwater runoff entering local waterways can be
mitigated by installing appropriate BMPs (Best Management Practices).
BMPs are any action or on-the-ground practice that reduces the amount of stormwater and
pollution flowing into waterways. On-the-ground BMPs such as rain gardens, rain barrels,
grassy swales,pervious pavement, and re-routing downspouts allow stormwater runoff to soak
into the ground and be cleaned and filtered naturally. Actions are such things as picking up
after pets, not blowing yard waste into storm drains, and putting litter in the trash can.
• Plants, shrubs, trees, and other vegetation can greatly reduce stormwater pollution by
absorbing and filtering stormwater runoff.
• Everyone CAN and SHOULD make a difference to improve and protect our waterways.
75

Best Practices
The mission of City of Wilmington Stormwater Services is to provide comprehensive
management of the stormwater drainage system in order to protect our community and the
environment.
The City of Wilmington Stormwater Services strives to improve local water quality by creating
awareness of stormwater runoff issues ultimately resulting in behavior change through public
education, outreach, and community involvement. We also aim to involve the public by providing
opportunities for the community to get involved in hands-on stormwater activities and to provide
input and feedback on local stormwater issues.
Our program informs and creates awareness for citizens, businesses, and employees about the
stormwater drainage system, sources of stormwater pollution, the impacts of stormwater pollution
on local waterways. We also highly focus on solutions and practices we can do as individuals and
as a community to mitigate stormwater pollution through personal stewardship and community
action.
Our programming is based on the principles of social marketing, which is broadly defined as
"using marketing principles and techniques to communicate and influence a target audience to
voluntarily change a behavior for the benefit of individuals, groups, or society as a whole." Social
marketing campaigns should appeal to the values of the target audience. Values can include saving
money, protecting public health, improving the environment, opening waters to shellfish
harvesting,preventing swimming advisories,being a good steward, etc.
Best practice for developing outreach/education and involvement/participation programming
follows the steps below as illustrated in the EPA's Getting in Step: A Guide for Conducting
Watershed Outreach Programs, 3rd Edition:
1) Identify Driving Forces, Establish Goals, and (SMART) Objectives
2) Identify the Target Audience(s)
3) Create your Message
4) Package your Message (format)
5) Distribute your Message
6) Evaluate your Plan/Campaign
Once driving forces/goals/objectives are developed, identifying and analyzing the target audience
is one of the most critical steps for developing an outreach/education campaign. Target audiences
are commonly identified by demographics, activities, occupation, location, current knowledge,
attitudes and beliefs, behavior patterns, social/cultural behaviors, and education level.
It is also important to identify any potential barriers to adoption of stormwater-friendly behaviors
within the target audience. Barriers can be physical, economic, psychological, time,
inconvenience, lack of awareness, etc. For instance, some pet owners believe that leaving pet
waste on the ground is a natural fertilizer, without realizing the negative bacterial impacts on
76

water quality and public health. Barriers should be addressed by your programming so that they
are minimized or removed and the benefits to behavior change are positively conveyed.
Packaging/formatting and distributing your campaign messages are vital to achieving success with
your campaign. The target audience should always be considered when determining the
appropriate methods to reach them with campaign messages or efforts to involve them. Formats
and distribution methods range from mass media outlets for messaging to large events and field
trips to more intimate formats such as focus groups, neighborhood meetings, email newsletters,
and presentations. Other outreach formats include print materials, giveaways, websites, and social
media platforms.
For each of the identified pollutants in our plan, outreach messages will be created/adapted,
packaged, and distributed for each specific target audience at the time of outreach. It is also
important to form partnerships and community collaborations whenever possible, to jointly work
on outreach/education campaigns with other agencies that have similar goals or may already have
a similar program or message in place.
Evaluating your outreach/participation programs and activities is extremely important for
determining success, areas for improvement or adjustment, and future directions for your program.
"The success of outreach programs depends on how well they're conceived, planned,
implemented, and adapted. Developing solid objectives and determining the appropriate target
audience at the start is key to measuring success."
Building evaluation tools, like those suggested below, into your outreach campaign at the
beginning, along the way, and at the conclusion of programming, is important for adapting your
future programs so they are successful. There are several types of evaluation:
• Process Evaluations involve evaluating the campaign and components during
implementation(i.e. budget, schedules, resources, staffing, activities, costs, materials, etc.)
• Impact Evaluations help you determine if you've met or impacted the goals and objectives
of the program and measure the impact of the campaign on the target audience (i.e. pre-and
post surveys, Google Analytics, water quality improvement, social indicators/behavior
changes, increased awareness, changed attitudes, reduced barriers, etc.)
• Contextual Evaluations include indicators of how the campaign/program impacts the
community, economy,politics, perceptions, cultural factors, etc.
• Observation includes monitoring audiences for changes in observed behavior (i.e. pet
owners cleaning up after pets, lawn care companies are no longer blowing yard waste
into streets, etc.)

Overview Target Pollutants, Sources, and Audiences:
The target audiences and pollutants identified in the Stormwater Management Plan (SWMP) are
directly addressed by this Public Education/Outreach and Involvement/Participation Plan.
In addition, the City of Wilmington's Stormwater Compliance Officers are required to inform and
educate property owners and the general public about the hazards associated with illicit
discharges, illegal dumping and the improper disposal of waste, as well as the city's pet waste and
yard waste regulations. The city has a robust program and many methods of reaching target
audiences most likely to have an impact on the stormwater system.
By identifying target audiences enables the city to develop programming for these audiences.
Programming includes direct classroom presentations, distributing educational materials to the
community content in the City's public newsletter reaching 44,000 residents and businesses, mass
media/social media campaigns, participating in community events to directly engage with
residents and property owners, and hands-on activities such as watershed/creek cleanups, storm
drain marking, and the CreekWatchers monitoring program.
Our program addresses major pollutants that have an impact Wilmington's waterways. These
pollutants come mainly from nonpoint sources, however, we may address commercial and
industrial sources of water pollution,particularly through our compliance and illicit discharge
program. Most major industry lies outside of the city limits.
The following descriptions identify pollutants, sources, and audiences that have or are likely to
have an impact on Wilmington's waterways, including residential and commercial
business/industrial sources. Many of these identified pollutants, such as litter and yard waste, can
also negatively impact the proper functioning of the stormwater drainage system.
These particular pollutants, sources, and audiences were chosen based on several sources
including UNCW's water quality monitoring data, the City of Wilmington Stormwater Services
maintenance activities, Stormwater Compliance Officers data on stormwater violations,
education/outreach program data,New Hanover Animal Control statistics, and the Statewide
Stormwater Survey of North Carolina residents, and 2019 SC Stormwater Survey, as well as
anecdotal community observations.
Pollutant: Fecal Coliform Bacteria/Pet Waste
Fecal coliform bacteria is the #1 pollution problem impacting Wilmington's creeks and
waterways, as identified through annual water quality monitoring by UNCW. Primary sources of
this bacterial pollution is pet waste. Occasional, episodic sewer spills also contribute to bacterial
pollution,but this is a less frequent source of contamination. Background sources like waterfowl
in Greenfield Lake also impact bacterial levels. Fecal bacterial pollution has resulted in the direct
closure of shellfish harvesting beds in tidal creeks throughout Wilmington.
UNCW has found a direct correlation between the amount of impervious surface coverage and the
degradation of Wilmington's waterways. A watershed restoration plan is being implemented in
two high priority creeks to reduce fecal bacterial pollution and eventually reopen shellfish
harvesting in Bradley& Hewletts Creeks. Likely sources of fecal coliform pollution are pet
owners and pet-related businesses, as well as sanitary sewer system overflows under management
of the Cape Fear Public Utility Authority and background sources like birds and wildlife.
79

Target Audience:
Domesticated dog waste is a major source of bacterial pollution, especially considering
their population(nearly 55,000 in New Hanover County), daily defecation rates, and
bacterial production. One gram of dog waste (weight of a paperclip) can contain nearly 23
million fecal bacteria. Feral and outdoor cats are also a problem for these same reasons;
steps should be taken to control their waste as well.
By right of ownership, a pet owner has the power to reduce pet waste-contaminated runoff
by cleaning up after their pet. Survey data reports both females and males should be
targeted, with a slightly higher% of males not picking up after pets. In addition to pet
owners, targeting pet-related businesses will educate those in the profession about best
practices for pet waste management and also serve as a conduit to deliver outreach
messages to the public.
Bacterial pollution attributed to wildlife and waterfowl is not a source that can be easily
managed, but the city and contracted staff at Cape Fear River Watch make efforts to
educate the public about not feeding wildlife/waterfowl,particularly at Greenfield Lake.
Feeding wildlife habituates them to stay in an area if there is a regular source of external
food, adding both bacteria and nutrients to a waterbody.
Private property owners within the Bradley and Hewletts Creeks Watersheds are also able
to reduce the volume of stormwater that can transport fecal coliform to these creeks by
implementing best management practices (BMPs) on residential or commercial properties,
through the assistance of the city's Heal Our Waterways (HOW) Program.
Pollutant: Nutrients/Yard Waste
Nutrient pollution, caused by nitrogen and phosphorous inputs, have been identified as a pollutant
of concern for causing algal blooms, low dissolved oxygen levels, and resulting fish kills.
Background sources of nitrogen and phosphorous can be attributed to wildlife/waterfowl.
Greenfield Lake has experienced all of these issues. Likely sources of nutrient pollution include
improper fertilization and/or improper yard waste disposal practices by landscaping companies
and residents. UNCW water quality data has indicated algal blooms in local creeks, as well as low
DO, and occasional fish kills.
Target Audience:
A direct link exists between nutrient pollution(nitrogen&phosphorous) and poor water
quality. This has been researched by UNCW particularly on Greenfield Lake.
The target audiences for this pollutant are overwhelmingly male and include residents and
landscaping companies. The city's Stormwater Compliance Officer routinely investigates
and responds to complaints of landscaping companies and/or homeowners blowing yard
debris into the street and storm drainage system.
The city and Cape Fear River Watch educate the public about not feeding
wildlife/waterfowl, particularly at Greenfield Lake. Feeding wildlife habituates them to
stay in an area if there is a regular source of external food, adding both bacteria and
nutrients to a waterbody. In addition, the city has worked to educate the public about
harmful cyanobacteria blooms that have unfortunately occurred in Greenfield Lake.
Educational efforts have included cyanobacteria outreach materials, dedicated displays,
and social media posts, as well as educational signs posted at every city-owned retention
pond and wetland. In 2022, UNCW also began a study of city-owned retention ponds to
80

sample for algal blooms and toxins, fecal bacteria and other water quality measures and
sample sediments for toxic chemicals, heavy metals, nitrogen and phosphorous.
Pollutant: Litter
Litter is ubiquitous and is especially problematic for the stormwater drainage system and for
wildlife and aquatic habitat. Litter often takes a long time to degrade. It can be mistaken by fish,
birds and other wildlife as a food source, resulting in them becoming sick or dying from ingestion.
Aquatic and terrestrial wildlife can also become entangled in litter and die as a result. Litter
introduces chemical pollutants and toxins into waterways, such as those contained in plastics and
cigarette butts.
Litter is a stormwater issue associated with both commercial and residential areas.
Watershed/creek cleanups contracted with Cape Fear River Watch, as well as routine maintenance
by Stormwater crews, have identified litter as an ongoing problem in local watersheds. Likely
sources are pervasive across the city and include businesses,residences, students/schools,
motorists, construction sites, etc.
Target Audience:
Litter habits cannot be confined to a particular demographic in most cases. Therefore,
targeting the general public is advisable. However, focusing on 8th graders during annual
school presentations should be a priority, since they are in the developmental stage of
learning and forming opinions, and often report littering behaviors themselves during these
presentations.
The Stormwater Compliance Officer has dealt with numerous reports of illegal dumping
activity in the city. Although it is difficult to track down the offender, property owners are
held responsible for cleaning up illegal dump sites.
Pollutant: Sediment
Sediment is generated by the process of natural or accelerated erosion and consists of sand, dirt,
clay, or soil particles. While natural erosion contributes sediment to waterways, the majority of
sediment comes from areas where accelerated erosion has occurred, such as from land-disturbing
activities like construction. Stormwater runoff carries these soil particles to local creeks and
streams.
Sedimentation can clog the storm drain system or quickly fill in a waterbody potentially leading to
flooding. Sedimentation also impacts bottom-dwelling organisms by smothering fish eggs,
shellfish, coral and benthic (bottom-dwelling)plants. Sediment can cause water to become cloudy,
also known as turbidity. Turbidity impairs the photosynthesis of aquatic plants, as well as the
ability of aquatic animals to breathe, see prey/predators, and reproduce.
Sediment also serves as a"transport vehicle" for other pollutants such as nutrients, metals, and
bacteria. These pollutants attach to sediment particles and cause additional water quality issues
when the sediments are agitated(i.e. boating, hurricanes,wading, etc.) and can re-pollute the
water column. UNCW has documented incidents of this.
81

With the prevalence of fecal coliform bacteria and the propensity for sediment to transport it to
waterways, reducing sediment loading to creeks is beneficial for other pollutants of concern as
well.
Target Audience:
The environmental consequences of sedimentation are not widely understood by citizens.
Sources of sediment in our surface waters are primarily the result of human-related land
disturbing activities. Construction, landscaping companies, and related industries may
significantly contribute to sediment loading in area waterways. Homeowners can also be a
source of sediment pollution for activities conducted on the homefront including blowing
sediment, exposed soil, and having poorly vegetated areas.
Likely sources of sediment pollution in our area are the result of rapid construction across
the city resulting in land-disturbing activities, erosion of creek banks, exposed soil in
yards, improper disposal practices, and blowing sediment into the storm drainage system
by residents and landscapers.
Pollutant: Chemicals/Improper Disposal of Waste
Chemicals are a pollutant focus for the damage they can cause to aquatic and terrestrial
environments. Stormwater runoff washes harmful chemicals such as pesticides,pressure washing
cleaners, vehicle washing soaps and other illicit discharges directly into our waterways. Most of
these pollutant sources contain toxic chemicals that can persist in the environment, causing
toxicity in humans and aquatic organisms.
Pesticides have been known to cause negative changes to amphibians and other aquatic organisms
and bio-accumulate up the entire food chain to humans.
Instances of chemical pollution via illicit discharges or improper use or disposal are often found
by pollution reports to our stormwater pollution hotline or detected via routine investigations by
the Stormwater Compliance Officer. In addition, restaurant grease traps have been found to be
non-functioning and contributing to water pollution by our Stormwater Compliance Officer.
Residents and business employees have reported the improper disposal of waste (i.e. motor oil and
other chemicals) to the city. Sources are pervasive and result from businesses and residents
illegally discharging chemicals or waste into the environment or using chemicals improperly
resulting in leaks and spills.
Target Audience:
All citizens have the potential to contribute chemical pollution by washing items outdoors
(i.e. driveways, homes, lawn furniture),by using pesticides and other chemicals on their
property, or by improperly disposing of waste.
Businesses that wash surfaces outdoors often use cleaning agents containing chemicals that
are harmful to our waterways. These chemicals are easily washed into the storm drainage
system from impervious surfaces. Restaurants may clean equipment or dump mop
washwater outdoors illegally. Grease traps have also been found to be non-functioning at
area restaurants by the Stormwater Compliance Officers. The discharge of any type of
wastewater or washwater into the storm drainage system is unlawful and carries associated
fines that are addressed by our Stormwater Compliance Officer(s).
82

Pollutant: Illicit Discharges/Illegal Dumping
Any of the focus pollutants listed above could be a source of illicit discharge pollution or illegal
dumping. This can happen when pollutants are purposefully or inadvertently handled in a way
that results in pollution. For instance, pouring chemicals like pesticides or motor oil directly into a
storm drain; dumping trash in a specific location; or a business with a broken sewer line or grease
trap discharging into the environment.
Fortunately, the City of Wilmington employs two Compliance Officer that can detect and respond
to instances of illegal dumping, illicit discharge and improper disposal of waste.
These officers can enforce city stormwater ordinances with notices of violation and associated
fines. In addition, the city's Stormwater Pollution Prevention Hotline and web reporting form
allows citizens, employees, and businesses to report instances of stormwater pollution or potential
pollution. Compliance Officers respond to hotline and webform reports.
All of the pollutants above are woven into outreach materials, events, workshops,website and
school presentations. The pollutants, sources, audiences, messages, etc. are described in more
depth in the pages that follow.
83

Target Pollutant: FECAL COLIFORM BACTERIA
Fecal coliform bacteria are found in the guts and feces of domesticated and wild animals, as well
as in human waste. Stormwater runoff carries bacterial pollution from uncollected pet waste and
episodic sewer spills into local surface waters. Bacteria can contaminate waterways commonly
used for recreational activities such as swimming and fishing and commercial shellfish harvest.
Likely Residential Sources: Pet Owners, Wild Animals/Waterfowl, Stray/Feral Animals, Illicit
Discharges
Likely Commercial/Industrial Sources: Sewer Spills, Illicit Discharges, Pet-related Businesses
(i.e. doggie daycare, doggie parks,boarding facilities, etc.), Multi-Family Apartment Complex
Tenants, Schools
Other: Bradley&Hewletts Creek Residents and Businesses
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain.
• Fecal coliform bacteria is the #1 pollution problem impacting Wilmington's creeks and
waterways, as identified through annual water quality monitoring by UNC-Wilmington.
• The primary source of bacterial pollution is canine and outdoor cat waste. Occasional sewer
spills also contribute to bacterial pollution, but this is an infrequent source of contamination.
• Background sources such as waterfowl/wildlife can create fecal bacterial pollution issues in
waterbodies such as Greenfield Lake.
• Stormwater runoff washes bacteria, parasites, viruses, and nutrients from uncollected pet waste
directly into our waterways.
• Fecal bacteria is an indicator bacteria. High levels of fecal coliform bacteria indicate the
potential for diseases and infections by other pathogens upon contact. Pathogens such as
roundworm, salmonellosis, toxoplasmosis, E. coli, and gastroenteritis can be contracted via
contaminated water. These bacteria can make humans,pets, and other animals sick as well.
• Once in waterways, these pathogens can cause shellfish bed closures, recreational swimming
advisories, and impaired aquatic habitat.
• There is a direct correlation between the amount of impervious surface coverage and fecal
coliform bacteria counts and degradation in Wilmington's waterways, as cited by UNCW
research.
84

Target Pollutant: FECAL COLIFORM BACTERIA(pet waste, sewer spills)
Key Outreach Messages:
• Outreach/Education messages should make the connection between uncollected pet waste to impaired water
quality and human health impacts.
• Domesticated dog waste is a major source of bacterial pollution considering their population in New Hanover
County(55,000 registered dogs in 2019),daily defecation rate,and bacterial production. Outdoor cats are also a
problem for these same reasons and steps should be taken to control their waste outdoors as well.
• Although not a large source,educate the public about not feeding waterfowl/wildlife as it creates unnatural site
fidelity that leads to increased fecal contamination,particularly in Greenfield Lake.
• Bacteria can cause diseases and infections in humans,pets,and wildlife.
• Debunk barriers and myths to cleaning up after pets(i.e.it's not fertilizer,it's okay to use a bag to pick it up with
your hand,pet waste is still a problem even if it's in your own backyard,it can go in the landfill,etc.).
• Pet owners have a responsibility to clean up after pets and dispose of the waste properly,according to the city's
pet waste ordinance.
- Fully and immediately clean up after pets on any public property. (Public property consists of streets,
sidewalks, right of ways,parks,plazas,stream banks,public accesses,pathways, drainageways,storm
drains, creeks, officially accepted easements, etc.)
- Carry a clean-up device(i.e.bag,scooper)at all times.
- Show the clean-up device to a Code Enforcement Official,if requested.
- Bag and dispose of pet waste in a closed trash receptacle or refuse container.

86

Target Pollutant: NUTRIENTS
Nutrients, such as nitrogen and phosphorus,found in fertilizers and yard waste, enter our
waterways via stormwater runoff. High nutrient loads lead to algal blooms, low dissolved oxygen
levels,fish kills, and impaired aquatic habitat.
Likely Residential Sources: Homeowners, Landscaping Maintenance Companies
Likely Commercial/Industrial Sources: Growth/Urbanization, Landscaping Companies,
Schools
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain!
• Lawn fertilization and yard waste maintenance are two of the most widespread watershed
behaviors by both homeowners and landscaping companies.
• Improper application or over-application of fertilizer results in the introduction of nutrients
into our waterways via stormwater runoff.
• Yard waste (i.e. grass clippings, leaves, pinestraw) are often improperly blown or directed into
streets, storm drains, and ditches leading to clogged stormwater conveyances resulting in
flooding of streets and property. Yard debris can also wash into waterways via blowing the
material into streets and conveyances and by irrigation methods. This organic matter then
washes through the stormwater drainage system introducing nutrients into waterways.
• Fertilizers and yard waste that end up in local surface waters impact aquatic ecosystems
resulting in an overabundance of nutrients, a process known as eutrophication. Eutrophic water
conditions cause algal blooms. Once the excess nutrients are used up in a water body, the algae
will decompose using up the dissolved oxygen in the water, which aquatic organisms, like fish,
need to survive. This can cause fish kills.
• Algal blooms produced from eutrophic conditions also prevent sunlight from reaching benthic
(bottom-dwelling) aquatic plants and organisms.
• Some types of algal blooms are toxic to plants and animals, including humans. Domesticated
animals have passed by ingesting or coming in contact with water containing cyanobacteria.
87

Target Pollutant: NUTRIENTS (fertilizers,yard waste)
Key Outreach Messages:
• A direct link exists between improper fertilizer application and yard waste disposal to poor water quality resulting
in algal blooms,fish kills,and habitat degradation.
• Grasscycle! Leave grass clippings on the lawn to reduce or eliminate the need for fertilizer.Clippings conserve
soil moisture and act as a natural fertilizer.
• Compost yard waste and use the resulting material in your landscape or garden.
• Contain yard waste using proper collection methods for City pickup.
• Before fertilizing,get an inexpensive(and sometimes free)soil test from NHC Cooperative Extension. It will tell
you the exact nutrients your lawn needs and could save you time and money spent on fertilizing.
• Design and maintain lawns with the goal of absorbing runoff. For instance,minimize the use of lawn area and
fertilizer by replacing with native trees,shrubs,plants and groundcover.
• Use alternatives to fertilizer such as organic fertilizer,compost,grasscycling,worm poop,etc.
• If fertilizer must be used,read the label and apply correctly.Improper application includes over-applying by
frequency or volume,applying the wrong type,applying before rain,and failure to clean excess fertilizer from
driveways and streets after application.
• Improper disposal of yard waste(leaves,grass clippings,pine straw)can clog the storm drainage system causing
flooding of streets and property.
• Landscaping company employees should be trained on proper fertilization and yard waste disposal practices.
• Residents and businesses should be aware of and abide by the City's Yard Waste Ordinance:
- It is unlawful to rake,sweep,blow,wash,direct or place any debris into the storm drainage system. (The
storm drainage system consists of streets, storm drains, ditches,swales, creeks, lakes, rights-of-way,
dedicated easements, etc).
- Property owners shall keep all ditches,drains,swales,and other drainageways on their property free
from obstructions which would impede the flow of water.
- Fines for non-compliance with the City's yard waste ordinance are$250 per occurrence.
• Cyanobacteria or harmful algal blooms are the result of warmer conditions and excess nutrients.The community
should be educated about this condition and their role in reducing nutrient inputs into waterbodies.
• Utilizing BMPs,such as rain gardens,rain barrels,and re-routing downspouts to grassy areas allows polluted
runoff and nutrients to soak into the ground and be cleaned and filtered naturally.

Target Pollutant: LITTER
Litter is generated as a result of improperly or carelessly discarded plastics,food wrappers,
cigarette butts, etc. that wash into waterways via the storm drainage system. Litter impacts
aquatic and terrestrial habitat, wildlife, and water quality. Plastic pollution is ubiquitous and is
especially problematic for the drainage system and for wildlife and aquatic organisms. Litter often
takes a long time to break down, if at all.
Likely Residential Sources: Residents/General Public, Motorists, Smokers,Youth
Likely Commercial/Industrial Sources: Restaurants, Retail Centers, Construction Sites,
Schools
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain!
• Litter is carried by stormwater runoff into the drainage system where it can clog storm drains
and drainage conveyances and cause flooding on streets and property.
• Litter that washes into local surface waters can be mistaken by fish, birds and other wildlife as
food and become sick or die from ingesting it. Wildlife also become entangled in litter and die
as a result.
• Litter introduces chemical pollutants into waterways, such as those contained in plastics and
cigarette butts.
• Cigarette butts are a major source of litter and contain many dangerous toxins that can leach
into waterways. Butt filters often contain plastic fibers that don't degrade.
• Natural litter, like apple cores,banana peels, and fast-food waste can attract wildlife to
roadways and endanger their survival.
• Littered creates the "Broken Window" effect. Littered areas beget litter, while areas that are
cleaner tend to repel litter.
90

Target Pollutant: LITTER(plastics, cigarette butts,illegal dumping, etc.)
Key Outreach Messages:
• A direct link exists between wildlife impacts,habitat destruction,and poor water quality as a result of littering.
• Flooding of streets and property can often be attributed to the accumulation of litter in the drainage system.
• Wildlife,fish,and birds often mistake litter for food or become entangled in it,resulting in their demise.
• There are large areas of trash in our oceans,called Garbage Patches.
• Cigarette butts leach chemicals such as cadmium,lead,and arsenic into the aquatic environment within one hour
of contact with water.
• Cigarette butts and plastics are the most littered items in the world.
• Small plastic pieces are often found in fish species that humans eat.
• Litter attracts wildlife to the side of the road where they are likely to get hit by oncoming vehicles.
• The majority of litter found on beaches comes from inland locations.
• Littering and illegal dumping is against NC law and carries associated fines.
• Everyone has a personal responsibility for making sure that trash is disposed of properly,so it doesn't become
litter.

92

Target Pollutant: SEDIMENT
Sediment is generated by the process of natural or accelerated erosion and consists of sand, dirt,
clay, or soil particles. Sedimentation occurs when stormwater runoff carries sediment from a
disturbed land area or eroding stream bank to surface waters. Sediment can clog the stormwater
drainage system, can quickly fill in a waterbody, and cause turbidity and problems for aquatic
life.
Likely Residential Sources: Residential Yards/Driveways
Likely Commercial/Industrial Sources: Landscapers, Construction Sites
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain!
• Both natural and accelerated erosion produce sediment. Natural erosion is the process of
weathering that forms soil. Accelerated erosion is a result of land-disturbing activities by
humans that loosen topsoil, making the land more prone to erode quickly(i.e. construction-
related activities).
• While natural erosion contributes sediment to waterways, the majority of sediment comes from
areas where accelerated erosion has occurred, such as with construction sites. Stormwater
runoff carries soil particles from a disturbed area of land to local creeks and streams.
• Excessive sedimentation can fill in a water body or clog the storm drainage system, leading to
flooding. Sedimentation also impacts bottom-dwelling organisms by smothering fish eggs,
shellfish, coral and benthic (bottom-dwelling)plants.
• Sediment can cause a water to become cloudy, also known as turbidity. Turbidity impairs the
photosynthesis of aquatic plants, as well as the ability of aquatic animals to breathe, see
prey/predators, and reproduce.
• Sediment serves as a"transport vehicle" for other pollutants such as nutrients, metals, and
bacteria. These pollutants attach to sediment particles and cause additional water quality issues
when the sediment gets stirred up (i.e. boating, hurricanes, etc) and re-pollutes the water.
• Other sources of sediment include poorly vegetated areas in a yard or landscape.
93

Target Pollutant: SEDIMENT (sand, dirt, soil particles, exposed soil)
Key Outreach Messages:
• There is a direct link between sedimentation and poor water quality and impacts to aquatic ecosystems and
habitat.
• Any land-disturbing activity including gardening,tilling,construction,etc. can produce sediment which can lead
to flooding of streets and property when the sediment is carried into the storm drainage system via stormwater
runoff.
• Mulch should be used to cover exposed soil and prevent it from washing away.
• Sediment should be collected off paved surfaces and not rinsed or blown into the stormwater drainage system.
• Residents can plant groundcover,shrubs,and trees to hold soil in place and prevent erosion.Installing native
plants is preferred because they don't need fertilizers and pesticides.For properties with sandy soils,mix organic
matter(i.e. compost)in with the sand to allow plants to grow better.
• Lack of vegetation along waterfront property and streambanks can produce significant erosion.Waterfront
property owners should be encouraged to plant vegetative buffers and living shorelines to stabilize erosion.
• Developers should follow all sedimentation and construction site laws and practices.
• Construction site violations can be reported to the State Hotline: 1-866-STOP-MUD
• Utilizing BMPs,such as rain gardens,rain barrels,and re-routing downspouts to grassy areas,allows polluted
runoff to soak into the ground and be cleaned and filtered naturally.

Target Pollutant: CHEMICALS/IMPROPER DISPOSAL OF WASTE
Stormwater runoff washes harmful chemicals found in pesticides,pressure washing cleaners,
vehicle washing soaps, and other illicit discharges directly into our waterways. All of these
pollutants can contain toxic chemicals that can persist in the environment, causing toxicity in
humans and aquatic organisms. In addition, these pollutants may be illegally dumped,poured or
improperly disposed of which may cause entry into area waterways via the stormwater drainage
system. Nothing but clean water, devoid of chemicals, should enter the drainage system.
Likely Residential Sources: Homeowners, Gardening, Vehicle/Boat Owners, etc.
Likely Commercial/Industrial Sources: Pressure Washers, Vehicle Washing Businesses,
Turf/Landscape Professionals, Restaurants, Construction, etc.
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain!
• An illicit discharge (ID) is any unlawful disposal, placement, emptying, dumping, spillage,
leakage,pumping,pouring, emission, or other discharge of any substance other than stormwater
that enters the stormwater drainage system.
• The City's Illicit Discharge ordinance specifies that it is unlawful to dispose of or discharge any
substance other than stormwater into the storm drainage system. Fines are up to $10,000 per
offense.
• Chemicals and cleaning agents used to wash cars, boats, driveways and other impervious
surfaces are carried into storm drains and eventually into our waterways. These chemicals can
destroy the external mucus layer on fish that protects them from bacteria and parasitic
infections.
• Commonly used organophosphate pesticides are present in stormwater runoff and are toxic to
aquatic life in receiving water bodies.
• Pesticides bio-accumulate up the food chain and are harmful to beneficial fish, insects, pets,
wildlife, and humans, as well as entire aquatic ecosystems.
96

Target Pollutant: CHEMICALS/WASTE DISPOSAL (Pesticides,Pressure Washing,HHW,etc.)
Key Outreach Messages:
• There is a direct link between the use of chemicals on land(i.e.pesticides,pressure washing cleaners,etc.)and
water quality and habitat impacts(i.e. frogs with six legs).
• Promote info on how to properly dispose of chemicals and other household chemicals,including promotion of
Household Hazardous Waste Collection locations and events.
• Pressure washing surfaces,equipment,and vehicles using soaps or cleaning agents of any toxicity level can
negatively impact water quality and aquatic habitat. These surfaces can only be washed legally with plain,clear
water,unless there is an established,effective,legal,wastewater recapture system in place.
• If you must apply pesticides,read the labels and apply the correct amounts. Spot treat,and do not apply before
rain.
• Alternatively,install native plants which do not require pesticides or fertilizers.
• Use alternatives to pesticides such as ladybugs,weeding by hand,and organic pesticides.
• Suggest less toxic,environmentally friendly alternatives to pesticides and other chemicals.
• The City's Illicit Discharge ordinance specifies that it is unlawful to dispose of or discharge any substance other
than stormwater into the storm drainage system. Fines are up to$10,000 per offense.
- Anyone found responsible for causing a polluting substance to enter the storm drainage system will be
subject to a fine up to$10,000 per violation.
- The city will have the authority to enter property to inspect for illicit discharges,and if found,to require
that they be disconnected and permanently closed.
- Commercial businesses will not be permitted to wash vehicles,equipment,or any other surfaces with any
soaps or solvents or dislodge any other substance that may be harmful to surface waters,unless the
resulting wastewater is diverted to the sanitary sewer system.
- Restaurants will not be permitted to discharge any wastewater outside.
- Dumpster lids must be kept closed and dumpster plugs in place.
- Swimming pool water must be de-chlorinated before discharging.
- Floor drains in old buildings,connected to the storm drainage system,will be required to be

Target Pollutant: VEHICLE POLLUTION
Vehicle pollution comes from the intentional or unintentional disposal of vehicle fluids into our
waterways, some of which washes off impervious surfaces into the drainage system or is disposed
of improperly. Other avenues of contamination are from washing vehicles and boats with
soaps/detergents over impervious surfaces. These fluids are insoluble and can easily contaminate
water resources, as well as poison fish and other aquatic organisms.
Likely Residential Sources: Motorists, Backyard Mechanics
Likely Commercial/Industrial Sources: Vehicle Maintenance Repair Shops, Mobile Detailers,
Vehicle Dealership Lots
Background/Environmental Impacts:
• Storm drains and drainage conveyances (i.e. ditches) carry polluted runoff directly to local
waterways without any treatment. Only rain should go down the storm drain!
• Vehicles, including boats, have seals and gaskets that have the potential to leak a variety of
fluids, such as oil and grease. An accumulation of these fluids on roadways and parking lots
gets carried away by stormwater runoff which drains into waterways.
• Once vehicle pollution enters a body of water, it disperses quickly and forms a film on the
water's surface, making oxygen transfer from the surface to the bottom difficult, as well as
being toxic to fish and aquatic organisms.
• A common source of illegal dumping or draining of vehicle fluids is found to be the backyard
mechanic.
• 1 quart of motor oil can contaminate 250,000 gallons of water.
• It is a common watershed behavior to wash vehicles on impervious (hard) surfaces
• Washing vehicles or boats can cause nutrients, heavy metals, hydrocarbons and grime to wash
down the street and into waterways.
• Soaps and detergents used to wash vehicles or boats are carried into storm drains and
eventually into our waterways. These chemicals can destroy the external mucus layer on fish
that protects them from bacteria and parasitic infections.
• Vehicle washers are typically unaware of the content of washing soaps/detergents, why they
shouldn't wash on impervious surfaces, and their impact on water quality.
• Wash vehicles, boats, or equipment on grassy areas that can absorb and naturally filter
chemicals and washwater. This does not harm the lawn.
• Utilize commercial car washes because they recycle and/or treat their water onsite or discharge
to the wastewater treatment system.
99

Target Pollutant: VEHICLE POLLUTION (vehicle/boat fluids,washing)
Key Outreach Messages:
• There is a direct link between the introduction of vehicle fluids and water quality degradation,habitat destruction
and plant/animal death.
• All vehicles,machinery,and equipment that utilize vehicle fluids(i.e.oil,grease)for operation have the potential
to leak and contribute to water pollution.
• Keep vehicles tuned up,check and repair leaks,check tire pressure,and recycle or properly dispose of vehicle
fluids and batteries.
• Properly clean up vehicle leaks and fluid spills using an absorbent material(i.e.kitty litter)to soak up the spill.
Sweep up the contaminated absorbent,put in a sealed bag,and place in the trash.
• Driving less,carpooling or using alternative transportation are some of the best ways to prevent vehicle pollution.
• On-site storage(i.e. fluids,batteries)has the potential to leak during filling,emptying,storage unit failure,or
vandalism.
• Washing vehicles or boats using soaps/detergents can negatively affect water quality with chemicals,debris,or
sediment that is washed off of vehicles,driveways,parking lots,etc.
• Wash vehicles on the grass using a phosphate-free detergent or use a commercial car wash which recycles and
treats washwater,or set up a self-containment and capture system for the washwater.
• If you must wash on pavement,use plain,clear water and no chemicals.
• Commercial businesses should be aware of the City's Illicit Discharge ordinance specifies that it is unlawful to
dispose of or discharge any substance other than stormwater into the storm drainage system. Fines are up to
$10,000 per offense.
• Residential carwashing is exempted from enforcement;however the same principles are part of
outreach/education efforts.

Public Involvement & Participation:
"In the end we will conserve only what we love; we will love only what we understand;
and we will understand only what we are taught." (Baba Dioum, 1968).
Public participation and involvement in the stormwater program creates awareness, understanding,
and stewardship in citizens. Getting involved in hands-on stewardship is the best way to gain a
better understanding of how stormwater impacts our world, the environment and human health.
Our program involves contracting with two outside agencies to help fulfill Public involvement and
participation activities in the community. These agencies are:
• New Hanover Soil &Water Conservation District (NHSWCD)
• Cape Fear River Watch (CFRW)
Both agencies are responsible for recruiting and engaging volunteers and the community at large
in the following activities:
• Storm Drain Marking
• Creek/Watershed Cleanups
• CreekWatcher Monitoring Program
• Canines for Clean Water
These agencies also provide reports for each program as well as quarterly reports of all activities
conducted.
The city also engages the community through meetings, mailers, and doorhangers during planning
and construction of capital and in-house stormwater projects. Citizens can attend public meetings,
request one-on-one meetings, discuss projects with stormwater staff by phone or email, and
provide other input during the process.
In addition, the city has developed and heavily promoted a Stormwater Pollution Prevention
Hotline and web reporting form, for citizens, employees, and businesses to report stormwater
pollution in the community. Reports can be made anonymously.
Citizens can also get involved with the city's Heal Our Waterways Program, which is the effort to
implement the Bradley &Hewletts Watershed Restoration Plan. This plan relies on private
property owners to engage and be willing to install Best Management Practices (BMPs), often
with full-funding, in order to reduce the amount of bacterial pollution affecting Bradley&
Hewletts Creek. Public participation is the crux of this program.

Coordinate volunteer clean-ups of city watersheds/tributaries 10x per year, once per month
(with the exception of July and December). These cleanups will focus on tributaries that flow
into Greenfield Lake, Smith Creek, Burnt Mill Creek, Barnards Creek, Mott Creek, the Cape Fear
River, and as the need is discovered by the City.
10 monthly clean-ups will be completed including at least one site on the city's provided location
map/list for the International Coastal Cleanup, an annual international clean-up event.
A cleanup location map and list will be provided to CFRW and a field trip can also be conducted
by the city with CFRW, as necessary, to point out the cleanup locations. CFRW cleanups done in
conjunction with Keep America Beautiful must be performed at the locations identified by the
city, in order to be reimbursable under this contract.
In order to avoid duplication of cleanup activities, CFRW will provide a schedule to City
Stormwater Services 1 month in advance of proposed cleanup event locations. CFRW will inspect
these sites closer to the cleanup date to ensure that the specific location is still in need of a
cleanup.
Local watershed clean-ups may also include volunteer efforts to remove wetland and aquatic
invasive plants with a focus on Greenfield Lake, Kerr Ave, and the Mary Bridger Wetland, but
should not be conducted in place of cleanups.
Any cleanups conducted on private property should include written permission obtained in
advance of the cleanup by CFRW from the property owner. These "written permissions" should
be included with the Watershed Cleanup Report and on the year-end compilation of documents on
USB/DVD/CD submitted to the city.
Efforts should be made to inform the local media and social media outlets about upcoming
cleanup events. In addition, significant water quality problems or suspected problems identified
during cleanups will be reported immediately to the appropriate officials, including the city's
Stormwater Compliance Officer, Corey Boyett at 910-341-0092 or 910-343-4777.
A summary of each clean-up event will be completed and submitted to Stormwater Services.
Reports will be submitted using the supplied template and within 12 calendar days of the
cleanup event. Reports will include: the specific watershed, the location within the watershed that
was cleaned, number of community volunteers, hours worked, estimate of the quantity of waste
116

and recyclable materials removed, # of creek/ditch miles cleaned,photographs to document work
including before and after photos of the cleanup site, volunteer photos, and documentation of
efforts to secure volunteers and promote the event in the media and on social media. ($5973)

Purpose:
The purpose of this document is to establish agreed upon procedures for the Cape Fear Public
Utility Authority (CFPUA) to follow regarding reporting and documentation of sanitary sewer
overflows (SSO)that impact the City of Wilmington Municipal Separate Storm Sewer System
(MS4). These guidelines will enable the City to comply with NPDES Phase II Stormwater permit
reporting requirements as well as to provide assistance to CFPUA in mitigating any potential
threat to public health or the environment.
Reporting Requirements:
All SSOs resulting in discharge to the City of Wilmington MS4, or causing possible contamination
of stormwater discharging to the storm system, must be reported to the City within 48 hours of
occurrence in accordance with City Code Chapter 12, section 12-24. Failure to comply may result
in a notice of violation(NOV) for the CFPUA. Fines for non-compliance range up to $10,000
based on quantity, risk to the public, environment damage and degree of negligence as
documented in the City Code. The following table documents the minimum information required
for sanitary sewer overflows and sewage leaks that may impact the City's MS4.

(From Page 8 of City of Wilmington Illicit Detection and Elimination Program Manual)
Dry Weather Flow Inspection Program
In accordance with permit requirements for detecting dry weather flows, the City is developing
and implementing a program for conducting inspections throughout the MS4 to detect dry weather
flows. Dry weather flows are defined as any flow in the MS4 that occurs after a 72 hour period
without rain. The objective is to identify and eliminate flows that contain pollutant or pathogen
loads. Such flows vary in source, content, and frequency, thereby imparting variable impacts
within the larger MS4 and the final receiving water bodies. Promptly identifying dry weather
flows is instrumental in recognizing and addressing deleterious illicit discharges. As the program
develops, procedures will be evaluated and modified with the aim of more effectively detecting
and eliminating illicit discharges.
Employees of the City familiar with outfall inspection procedures will conduct the inspections.
Inspections will be conducted only during dry periods to facilitate identification of only those
flows unassociated with allowable stormwater flows. Furthermore, those outfalls located along
tidally influenced reaches will be inspected at low tide; should the outfall still be submerged at
low tide, the stormwater conduit will then be traced upgrade to the nearest manhole or observable
location beyond tidal influence, where an inspection will be more likely to detect a dry weather
flow. A similar modified observation procedure will be used for those points where direct
inspection of the outfall point is not possible; observations will be made immediately upgrade in
the system at an appropriate location for dry weather inspection.
The inspection itself will consist of an initial visual inspection of the outfall to determine the
presence or absence of water or liquid flow. Photographs will be taken of the inspection location
and saved along with the inspection record containing data describing the conditions observed at
the outfall or observation point. The detection of any suspicious dry weather flow will prompt a
service request for a field screening as described in later sections of this manual outlined as Steps
1-4, in which physical, chemical, and biological parameters may be analyzed to determine the
nature and source of any illicit discharge.
The inspection records will be stored in the GIS as tables. Screen shots of the actual ArcPad
routine and a diagram showing the database designed for storing these records is shown in
Appendix E: Field Data Collection of Dry Weather Inspections using ArcPad.
Given that the City is located in a coastal area with tidal influence in parts of the MS4 and
numerous groundwater sources infiltrating or directly routed into the MS4, our strategy for
performing the observations will be adjusted accordingly. The initial location of all major outfall
points has provided the starting point for the Dry Weather Flow Inspection Program. Each of the
major outfall points will be inspected,photographed and have an observation record saved to the
GIS database as described above. Following completion of this effort, a similar systematic
inspection of major trunk lines and areas of interest will begin.
The selection of major trunk lines for inspection will be a strategically targeted effort to isolate
139

those portions of the drainage system that may be contributing to any dry weather flow. At this
point, we envision inspections progressing up a selected trunk line from the outfall so that any
contributing dry weather flow source areas can be identified and investigation into the source can
begin. MS4 structures which have sewer cross pipes associated with them are at the greatest risk
for sewage contamination; therefore along with the trunk line inspection effort, special attention
will be given to inspecting any MS4 structures or junctions which have a sewer cross pipe passing
through the structure. Any identified illicit discharge encountered during the both the trunk line
and sewer cross pipe inspection process will result in a service request being generated.
The selection of major trunk lines and points along the trunk line for inspection will be scheduled
with consideration given to several influencing factors including: weather conditions, the degree to
which stormwater infrastructure mapping is reliable and complete within a given area, suspicion
of negative inputs to the MS4 based upon annual water quality reports, 303d listings, and/or
industrial land use designations. Also, indications of illicit discharge observations from the MS4
mapping crew will prompt inspections. Dry weather inspections will be performed at 25% of the
total number of outfalls per year depending on weather conditions.

APPENDIX E: CONSTRUCTION SITE RUNOFF CONTROLS
Included in this section:
New Hanover County Erosion & Sedimentation Control Ordinance
New Hanover County Ordinance:
The following are excerpts culled from the New Hanover County Erosion and Sedimentation
Control Ordinance:
The New Hanover County erosion and sedimentation control ordinance is adopted for the
purposes of:
(1) Regulating certain land disturbing activity to control accelerated erosion and sedimentation in
order to prevent the pollution of water and other damage to lakes, watercourses, and other public
and private property by sedimentation; and
(2) Establishing procedures through which these purposes can be fulfilled.
General requirements of the permit include among others:
(a) Plan required. No person shall initiate any land disturbing activity which uncovers more than
one acre without having an erosion control plan approved by the county.No land disturbing
activity may be initiated until the county is notified of the date that the land disturbing activity will
begin.
(b) Protection of property. Persons conducting land disturbing activity shall take all reasonable
measures to protect all public and private property from damage caused by such activity.
(c) More restrictive rules shall apply. Whenever conflicts exist between federal, state, or local
laws, ordinances, or rules, the more restrictive provision shall apply.
(e) Inspections. Any and all applicable intermediate inspections may be held in any trade
(building, mechanical, electric and/or plumbing) if any land disturbing activity, on a tract,
including single-family residences, is found not to be in compliance with any part of this article.
(f) Building finals. Building finals and/or certificates of occupancy may not be issued if any land
disturbing activity, including single-family residences, is found not to be in compliance with any
part of this article.
Mandatory Standards For Land Disturbing Activity
141

No land disturbing activity subject to the control of this article shall be undertaken except in
accordance with the following mandatory standards:
(1) Buffer zone.
a. No land disturbing activity during period of construction or improvement to land shall be
permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the
margin of the watercourse of sufficient width to confine visible siltation within the 25 percent of
the buffer zone nearer the land disturbing activity. Waters that have been classified as trout waters
by the environmental management commission shall have an undisturbed buffer zone 25 feet wide
or of sufficient width to confine visible siltation within the 25 percent of the buffer zone nearest
the land disturbing activity, whichever is greater. Provided, however, that the county may approve
plans which include land disturbing activity along trout waters when the duration of said
disturbance would be temporary and the extent of said disturbance would be minimal. This
subdivision shall not apply to a land disturbing activity in connection with the construction of
facilities to be located on, over, or under a lake or natural watercourse.
b. Unless otherwise provided, the width of a buffer zone is measured from the edge of the water
to the nearest edge of the disturbed area, with 25 percent of the strip nearer the land disturbing
activity containing natural or artificial means of confining visible siltation.
c. The 25-foot minimum width for an undisturbed buffer zone adjacent to designated trout waters
shall be measured horizontally from the top of the bank.
d. Where a temporary and minimal disturbance is permitted as an exception by subsection(1)a.
of this section, land disturbing activities in the buffer zone adjacent to designated trout waters
shall be limited to a maximum of ten percent of the total length of the buffer zone within the tract
to be distributed such that there is not more than 100 linear feet of disturbance in each 1,000 linear
feet of buffer zone. Larger areas may be disturbed with the written approval of the director.
e. No land disturbing activity shall be undertaken within a buffer zone adjacent to designated
trout waters that will cause adverse temperature fluctuations, as set forth in 15 NCAC 2B.0211
"Fresh Surface Water Classification and Standards", in these waters.
(2) Graded slopes and fills. The angle for graded slopes and fills shall be no greater than the
angle, from zero to nineteen degrees,which can be retained by vegetative cover or other adequate
erosion control devices or structures. Only when approved by the county may slopes be steeper
than two foot of run to one foot of rise. In any event, slopes left exposed will, within 15 working
days or 30 calendar days, whichever is shorter, of completion of any phase of grading, be planted
or otherwise provided with ground cover, devices, or structures sufficient to restrain erosion.
(3) Ground cover. Whenever land disturbing activity is undertaken on a tract comprising more
than one acre, if more than one acre is uncovered, the person conducting the land disturbing
activity shall install such sedimentation and erosion control devices and practices as are sufficient
to retain the sediment generated by the land disturbing activity within the boundaries of the tract
during construction upon and development of said tract, and shall plant or otherwise provide a
permanent ground cover sufficient to restrain erosion after completion of construction or
development. Except as provided in section 23-238(b)(5), provisions for a ground cover sufficient
142

to restrain erosion must be accomplished within 30 working days or 120 calendar days following
completion of construction or development whichever period is shorter.
(4) Prior plan approval. No person shall initiate any land disturbing activity on a tract if more
than one acre is to be uncovered unless, 30 or more days prior to initiating the activity, an erosion
and sedimentation control plan for such activity must be both filed with and approved by the
county. The county shall forward to the director of the division of water quality a copy of each
erosion and sedimentation control plan for a land disturbing activity that involves the utilization of
ditches for the purpose of dewatering or lowering the water table of the tract.
Design and Performance Standards.
(a) Except as provided in subsection (b)(2) of this section, erosion and sedimentation control
measures, structures and devices shall be so planned, designed and constructed as to provide
protection from the calculated maximum peak of runoff from the ten-year storm. Runoff rates
shall be calculated using the procedures in the USDA, Soil Conservation Service's "National
Engineering Field Manual for Conservation Practices," or other acceptable calculation procedures.
(b) In high quality water(HQW) zones, the following design standards shall apply:
(1) Uncovered areas in HQW zones shall be limited at any time to a maximum total area
within the boundaries of the tract of 20 acres. Only the portion of the land disturbing
activity within an HQW zone shall be governed by this section. Larger areas may be
uncovered within the boundaries of the tract with the written approval of the director.
(2) Erosion and sedimentation control measures, structures and devices within HQW
zones shall be so planned, designed and constructed to provide protection from the runoff
of the 25-year storm which produces the maximum peak rate of runoff as calculated
according to procedures in the United States Department of Agriculture Soil Conservation
Service's "National Engineering Field Manual for Conservation Practices" or according to
procedures adopted by any other agency of this state or the United States or any generally
recognized organization or association.
(3) Sediment basins within HQW zones shall be designed and constructed such that the
basin will have a settling efficiency of at least 70 percent for the 40-micron (0.04 mm)
size soil particle transported into the basin by the runoff of that two-year storm which
produces the maximum peak rate of runoff as calculated according to procedures in the
United States Department of Agriculture Soil Conservation Services "National
Engineering Field Manual for Conservation Practices" or according to procedures adopted
by any other agency of this state or the United States or any generally recognized
organization or association.
(4) Newly constructed open channels in HQW zones shall be designed and constructed
with side slopes no steeper than three horizontal to one vertical if a vegetative cover is
used for stabilization unless soil conditions permit a steeper slope or where the slopes are
stabilized by using mechanical devices, structural devices or other acceptable ditch liners.
In any event, the angle for side slopes shall be sufficient to restrain accelerated erosion.
143

(5) Ground cover sufficient to restrain erosion must be provided for any portion of a land
disturbing activity in a HQW zone within 15 working days or 60 calendar days following
completion of construction or development, whichever period is shorter.
Responsibility For Maintenance.
During the development of a site,the person conducting the land disturbing activity shall install and/or
maintain all temporary and permanent erosion and sedimentation control measures as required by the
approved plan or any provision of this article,the act, or any order adopted pursuant to this article or the
act. After site development,the land owner or person in possession or control of the land shall install and/or
maintain all necessary permanent erosion and sediment control measures, except those measures installed
within a road or street right-of-way or easement accepted for maintenance by a governmental agency.

HOWBMP Quarterly Progress Report#4: April 1 —June 30, 2022
Heal Our Waterways- Best Management Practice Installations (HOWBMP) Program
NHSWCD mission is to protect and enhance water quality throughout New Hanover County
through land conservation, stormwater management, technical support to citizens and
organizations, and conservation education and outreach activities.
To achieve this mission,NHSWCD has contractual relationships with city, county, and state
organizations. These partnerships enable NHSWCD to deliver enhanced water quality projects and
programs, as well as professional technical assistance to citizens and businesses.
SCOPE OF SERVICES:
New Hanover Soil & Water Conservation District will serve as the program/project manager to
implement the Heal Our Waterways- Best Management Practice Installations Program
(HOWBMP). The HOWBMP Program supports the City council-adopted Bradley & Hewletts
Creek Watershed Restoration Plan, with the goal of reducing the volume of polluted stormwater
runoff entering the creeks, to improve water quality.
NHSWCD will provide program and project management, implementation, reporting, and
evaluation for the installation of BMPs within the designated watersheds in conjunction with the
City's Heal Our Waterways Program. This includes the execution of a BMP project from start to
finish following Standard Operating Procedure (SOP) guidelines and includes activities such as,
but not limited to, program promotion and outreach, cultivating and identifying BMP project
opportunities, collaboration, coordination, and timely communication with property owners and
contractors, property owner and HOA research and verification, technical assistance,
design/engineering,permitting, contracting, construction, media relations,budgeting, selection
and reimbursement of contractors, monitoring of completed projects, and reporting. NHSWCD
will utilize contractors with the proper credentials and qualifications for the work performed.
BMPs will be identified for the purpose of reducing runoff volume and pollution into Bradley
Creek, Hewletts Creek, and the associated areas that"drain directly" into the Intracoastal
Waterway. A potential BMP project's pre-approval documentation should be provided to the City
in written/email form and include the required BMP, Property Ownership, Contractor, and
Ranking Sheet documentation, as listed in the SOP. NHSWCD will receive a written/email
response from the City to approve or deny the project, with justification. City approval must be
acquired before installation, construction, or other contracted work. Acceptable BMPs for the
164

program are listed on the GIS Atlas Sheet. Projects that NHSWCD evaluate and deem to be
unworthy of funding and installation will still require the proper documentation and justification to
the City, which will be included in the City's GIS Atlas.
A recommended minimum of 5-8 volume-reduction BMPs resulting in a total of approximately
700-1000 cubic feet of volume reduction should be installed during each annual contract period.
However, collaboration and written approval from the City would allow flexibility for unexpected
project opportunities to deviate from the recommended minimum. BMP projects should be
evaluated and prioritized based on several variables including volume reduction, benefit, cost, and
proximity to impaired waterbodies, etc.
During site evaluations, NHSWCD will utilize the required checklists to evaluate the site and
potential BMP(s), as well as communicate program specifics to the property owner. For instance,
NHSWCD will educate property owners about the Heal Our Waterways Program background, the
HOWBMP Program, the specific BMP being evaluated, maintenance expectations and annual spot
checks for the potential BMP, and will distribute pertinent info to the homeowner(maintenance
guide, BMP info sheet, HOW Brochure, business cards, etc.)
Once BMPs are installed to satisfaction,NHSWCD will provide the property owner with more
specific BMP maintenance information on-site, obtain a signed Maintenance Agreement from the
property owner, distribute Creek Friendly yard signage and other pertinent information and
program items.
Monitoring, or spot-checks, of completed BMP installations will be performed annually by
NHSWCD for compliance. Monitoring will be required for five years for residential sites, and ten
years for commercial or municipal/other BMP sites. NHSWCD will maintain a Spot Check
Tracking Summary excel database for all installations and submit it at the end of each annual
contract period. Refer to the SOP for the specific data to be included in this database.
The BMP installations will be funded by the City with a lump-sum allocation at the beginning of
the annual contract period. Any unused funds from this allocation will be reimbursed to the City
by July 30th. NHSWCD will issue any necessary tax forms to contractors or property owners.

defined in 40 CFR 122.26.
Large or Medium Municipal Separate Storm Sewer System
All municipal separate storm sewers that are either:
(a) Located in an incorporated place with a population of 100,000 or more as
determined by the Decennial Census by the Bureau of Census; or
(b) Located in the counties with unincorporated urbanized populations of

Major municipal separate storm sewer outfall (or "major outfall")
Major municipal separate storm sewer outfall (or "major outfall") means a municipal
separate storm sewer outfall that discharges from a single pipe with an inside diameter of
36 inches or more or its equivalent (discharge from a single conveyance other than
circular pipe which is associated with a drainage area of more than 50 acres); or for
municipal separate storm sewers that receive storm water from lands zoned for industrial
activity (based on comprehensive zoning plans or the equivalent), an outfall that
discharges from a single pipe with an inside diameter of 12 inches or more or from its
equivalent (discharge from other than a circular pipe associated with a drainage area of 2
acres or more).
Municipal Separate Storm Sewer System (MS4)
Pursuant to 40 CFR 122.26(b)(8) means a conveyance or system of conveyances (including
roads with drainage systems, municipal streets, catch basins,curbs, gutters, ditches,manmade
channels, or storm drains):
(a) Owned or operated by the United States, a State, city, town, county,
district, association, or other public body (created by or pursuant to State
law)having jurisdiction over disposal of sewage, industrial wastes,
stormwater, or other wastes, including special districts under State law
such as a sewer district, flood control district or drainage district, or
similar entity, or an Indian tribe or an authorized Indian tribal
organization, or a designated and approved management agency under
Section 208 of the Clean Water Act(CWA) that discharges to waters of
the United States or waters of the State.
(b) Designed or used for collecting or conveying
stormwater;
(c) Which is not a combined sewer; and
(d) Which is not part of a Publicly Owned Treatment Works (POTW) as defined
in 40 CFR 122.2
179

Non-stormwater Discharge Categories
The following are categories of non-stormwater discharges that the permittee shall
address if it identifies them as significant contributors of pollutants to the storm sewer
system: water line flushing, landscape irrigation, diverted stream flows, rising
groundwater, uncontaminated groundwater infiltration, [as defined in 40 CFR
35.2005(20)], uncontaminated pumped groundwater, discharges from potable water
sources, foundation drains, air conditioning condensation, irrigation water, springs,
water from crawl space pumps, footing drains, lawn watering, individual residential car
washing, flows from riparian habitats and wetlands, dechlorinated swimming pool
discharges, and street wash water(discharges or flows from fire fighting activities are
excluded from the definition of illicit discharge and only need to be addressed where
they are identified as significant sources of pollutants to waters of the United States).
Non-structural SCM
Non-structural SCMs are preventive actions that involve management and source controls
such as: (I) Policies and ordinances that provide requirements and standards to direct
growth to identified areas, protect sensitive areas such as wetlands and riparian areas,
maintain and/or increase open space, provide buffers along sensitive water bodies,
minimize impervious surfaces, and/or minimize disturbance of soils and vegetation; (2)
policies or ordinances that encourage infill development in higher density urban areas, and
areas with existing storm sewer infrastructure; (3) education programs for developers and
the public about minimizing water quality impacts; (4) other measures such as minimizing
the percentage of impervious area after development, use of measures to minimize directly
connected impervious areas, and source control measures often thought of as good
housekeeping, preventive maintenance and spill prevention.
Outfall
Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal
separate storm sewer discharges to waters of the United States and does not include open
conveyances connecting two municipal separate storm sewers, or pipes, tunnels or other
conveyances which connect segments of the same stream or other waters of the United
States and are used to convey waters of the United States.
Permittee
The owner or operator issued this permit.
Point Source Discharge of Stormwater
Any discernible, confined and discrete conveyance including, but not specifically limited
to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which
stormwater is or may be discharged to waters of the state.
Redevelopment
Means any rebuilding activity unless that rebuilding activity;
(a)Results in no net increase in built-upon area, and
(b)Provides equal or greater stormwater control than the previous development.
Representative Storm Event
180

A storm event that measures greater than 0.1 inches of rainfall and that is preceded
by at least 72 hours in which no storm event measuring greater than 0.1 inches has
occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable
discharge, and then stops,a sample may be collected if a rain producing a discharge
begins again within the next 10 hours.
Storm Sewer System
Is a conveyance or system of conveyances which are designed or used to collect or
convey stormwater runoff that is not part of a combined sewer system or treatment
works. This can include, but is not limited to, streets, catch basins, curbs, gutters,
ditches, man-made channels or storm drains that convey stormwater runoff.
Stormwater Associated with Industrial Activity
The discharge from any point source which is used for collecting and conveying
stormwater and which is directly related to manufacturing, processing or raw material
storage areas at an industrial site. Facilities considered to be engaged in "industrial
activities" include those activities defined in 40 CFR 122.26(b)(14). The term does not
include discharges from facilities or activities excluded from the NPDES program
Stormwater Control Measure (SCM)
Measures or practices used to reduce the amount of pollution entering surface waters.
SCMs can be structural or non-structural and may take the form of a process, activity,
physical structure or planning (see non-structural SCM).
Stormwater Management Program (SWMP)
The term Stormwater Management Program (SWMP) refers to the stormwater
management program that is required by the Phase I and Phase II regulations to be
developed by MS4 permittees.
Stormwater Plan
The Stormwater Plan is the written plan that is used to describe the various control
measures and activities the permittee will undertake to implement the stormwater
management program. The Stormwater Plan is a consolidation of all of the permittee's
relevant ordinances or other regulatory requirements, the description of all programs
and procedures (including standard forms to be used for reports and inspections) that
will be implemented and enforced to comply with the permit and to document the
selection, design, and installation of all stormwater control measures.
Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately
following rainfall or as a result of snowmelt.
Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can
receive and still meet water quality standards, and an allocation of that amount to the
pollutant's sources. A TMDL is a detailed water quality assessment that provides the
181

scientific foundation for an implementation plan. The implementation plan outlines the
steps necessary to reduce pollutant loads in a certain body of water to restore and maintain
water quality standards in all seasons. The Clean Water Act, Section 303, establishes the
water quality standards and TMDL programs.
Watershed Restoration Plan
For purposes of this permit, a Watershed Restoration Plan is any plan developed in
consultation with the Division for voluntary implementation with the intent of enhancing
water quality and/or implementing stormwater BMPs within 303(d) listed waters.
