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, 2018 to June 30, 2019.
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 1 compliance with requirements of
NPDES Phase II permit NCS000406. Primary areas of work include:
 Continued implementation of amended ordinances related to Post Construction and Illicit Discharge
BMPs.
 Continued mapping of stormwater infrastructure along with improvements to the GIS
database design.
 Continuation of Public Outreach and Public Participation efforts.
 Continued implementation of SPPP and SPCC plans and inventory of municipally owned operations
with the potential to pollute.
 Hired Watershed Coordinator who began implementation of the Watershed Restoration Plans for
Bradley and Hewletts Creek watersheds.

Wilmington continues to move forward with implementing the necessary goals and objectives as
outlined in their permit. Considerable progress related to Illicit Discharge Detection and Elimination has
been made during the past year with respect to dry weather flow monitoring and planning. 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 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 two semi-annual inspections for privately
permitted 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 departments, outside agencies, and citizens in
affected areas. Whenever feasible, capital improvement projects incorporate innovative design or
stormwater control measures (SCM’s) to improve water quality and reduce the volume of stormwater
runoff.

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.

3

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. Porous pavement is also maintained by this section.
SCM inspections and maintenance consists of activities necessary to manage over 60 city-owned SCM
facilities; including wet ponds, constructed wetlands, bio-retention and infiltration facilities in
functioning condition.

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
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.
These efforts strive to 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 2018-2019, a total of 2 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 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

Reports of pet waste violations receive a face to face meeting if possible. A brochure and flyer has been
developed explaining 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.

7

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 t o
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 i n 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).
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

12

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 combined results of Year 21 of the Wilmington Watersheds Project.
Water quality data are presented from a watershed perspective, regardless of political
boundaries. The 2018 program involved 9 watersheds and 24 sampling stations. In this
summary we first present brief water quality overviews for each watershed from data collected
between January and December 2018; note that fewer samples were collected at some sites in
2018 because funding did not arrive until late fall; additionally, Hurricane Florence disrupted
sampling as well..
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. Dissolved oxygen concentrations were good on all sampling occasions,
and turbidity was within standard. However, one major and one minor algal bloom occurred.
Fecal coliform counts were somewhat elevated on two occasions.
Bradley Creek – Bradley Creek drains a watershed of 4,583 acres, including much of the
UNCW campus, into the Atlantic Intracoastal Waterway (AICW). The watershed contains about
27.8% impervious surface coverage, with a population of about 16,470. Three sites were
sampled, all from shore. In 2018 there were no significant algal blooms recorded, but there
were several incidents of low dissolved oxygen, especially at the uppermost site BC-CA on
College Acres. All three sites sampled were rated poor due to high fecal coliform bacteria, with
the College Acres station BC-CA having especially high counts.
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 2018.
High fecal coliform counts occurred at all three sites in 2018, especially at the uppermost site
BMC-AP1 above Anne McCrary Pond and at the lowermost station BMC-PP at princess Place.
Several major algal blooms (chlorophyll a > 40 µg/L) were recorded in 2018. Dissolved
oxygen concentrations were good in the two upper stations and poor in the remaining lower
creek site.
The effectiveness of Ann McCrary wet detention pond on Randall Parkway as a pollution
control device for upper Burnt Mill Creek was mixed for 2018. Comparing inflows to outflows,
there was a significant increase in dissolved oxygen concentrations as the water passed through
the pond due to in-pond algal photosynthesis and physical aeration at the outfall. There was
likewise a significant increase in pH due to photosynthesis using up CO2 (an acid) and driving
the water to a more alkaline state.
On a positive pollutant –reduction note, ammonium concentrations significantly decreased
through the detention pond.

16

Several water quality parameters showed an increase in pollutant levels along the creek from the
exit from the detention pond to the downstream Princess Place sampling station, including fecal
coliform bacteria, orthophosphate, ammonium and nitrate.
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 four tributary sites and three in-lake sites. Of the four tributaries
of Greenfield Lake, Squash Branch ( near Lake Branch Drive), Jumping Run Branch at 17th
Street, Jumping Run Branch at Lakeshore Dr., and Clay Bottom Branch (near Lakeshore
Commons Apartments), two suffered from low dissolved oxygen problems, although main lake
maintained good oxygen concentrations on all sampling occasions (non-hurricane periods).
Algal blooms are periodically problematic in Greenfield Lake, and have occurred during all
seasons, but are primarily a problem in spring and summer. In 2018 a massive summer blue-
green algal bloom of Anabaena occurred late spring – late fall. In the period 2007-2013 there was
a statistically significant relationship within the lake between chlorophyll a and five-day
biochemical oxygen demand (BOD5) meaning that the algal blooms are an important cause of
low dissolved oxygen in this lake, and very high BOD occurred congruent with the blooms in
2018. In 2018 all tributary stations and one of the in-lake stations exceeded the fecal coliform
State standard on 66% or more of occasions sampled.
We note that Greenfield Lake suffered a fish kill of about 600 fish in the discharge canal in
August, then suffered a massive fish kill involving thousands of fish or many species in late
September following Hurricane Florence. Cape Fear River Watch personnel reported low
dissolved oxygen in association with the September kill. Nutrient loading from hurricane runoff,
coupled with decomposition of dead fish likely contributed nutrients that kept the algal blooms
occurring until fall.
Greenfield Lake is currently on the NC 303(d) list for impaired waters due to excessive algal
blooms. In the previous report we reported on the thesis work of UNCW graduate student Nick
Iraola, who performed wet-period and dry-period sampling of the five main inflowing tributaries
to the lake to assess where the principal nutrient inputs came from. The results showed that the
largest inorganic nutrient loads came in from Jumping Run Branch and Squash Branch, and best
management practices (BMPs) to reduce nutrient loading should be targeted for those streams. In
summer 2018 UNCW personnel collected bottom sediment samples at 27 locations within the
lake, finding the highest phosphorus levels in Jumping Run and Squash Branch, and lowest levels
in areas of significant natural wetlands, again providing guidance for restoration work.
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 2018 the creek was sampled at four tidal sites and one non-tidal
freshwater site (PV-GC-9).
Incidents of low dissolved oxygen were rare at Hewletts Creek in 2018; DO dipped below 5.0
mg/L on several occasions but not below 4.0 mg/L. Turbidity was low and did not exceed the

17

state standard. Two major algal blooms occurred at PVGC-9 following Hurricane Florence, and
one bloom occurred in summer at SB-PGR. Fecal coliform bacteria counts exceeded State
standard 100% of the time at NB-GLR (the north branch) and MB-PGR (the middle branch), 83%
of the time at PVGC-9, and 67% of the time at SB-PGR (the south branch). The geometric means
at PVGC-9, MB-PGR, SB- PGR and NB-GLR all exceeded 200 CFU/100 mL for a poor rating
for this pollutant parameter, but the geometric mean of fecal bacteria counts at HC-3 was well
under the state standard.
Howe Creek – Howe Creek drains a 3,516 acre watershed into the AICW. This watershed hosts a
population of approximately 6,460 with about 21.4% impervious surface coverage. Two stations
were sampled in Howe Creek in 2018. The uppermost site HW-DT had two major algal blooms
in the 2018 sampling, and the middle creek station had one bloom. The uppermost station HW-
DT was rated poor for fecal coliform pollution in 2018, exceeding the state standard on 75% of
the times sampled.
However, dissolved oxygen concentrations were good at both sites in 2018.
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%. One major and one minor
algal bloom occurred at our site in 2018. Dissolved oxygen concentrations were fair in 2018, and
turbidity was low. Motts Creek was strongly impacted by high fecal coliform counts in 2018.
Smith Creek – Smith Creek drains into the lower Northeast Cape Fear River just upstream of
where it merges with the Cape Fear River. 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 three of 11 occasions in our 2018 samples. The North Carolina turbidity
standard for estuarine waters (25 NTU) was not exceeded. There were no major algal blooms
present in our 2018 sampling. However, fecal coliform bacterial concentrations exceeded 200
CFU/100 mL on 36% of samples in 2017, for a Poor rating, although it should be noted that fecal
coliform counts in 2018 were considerably lower than in 2017.
Whiskey Creek – Whiskey Creek is the southernmost large tidal creek in New Hanover County
that drains into the AICW. It has a watershed of 2,078 acres, a population of about 8,000, and is
covered by approximately 25.1% impervious surface area. One station, on Masonboro Loop
Road, was sampled from shore along this creek in 2018. This site had low to moderate nutrient
concentrations and no algal bloom problems.
Dissolved oxygen was substandard (below 5.0 mg/L) on one of six occasions sampled, and fecal
coliform bacteria counts exceeded 200 CFU/100 mL on 50% of occasions sampled.
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

18

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 2018 data, and have designated
each station as good, fair, and poor accordingly (Appendix B).
Fecal coliform bacterial conditions for the entire Wilmington City and New Hanover County
Watersheds system (24 sites sampled for fecal coliforms) showed 4% to be in good condition,
13% in fair condition and 83% in poor condition, a worsening over the previous year. Dissolved
oxygen conditions (measured at the surface) system-wide (24 sites) showed 54% of the sites were
in good condition, 8% were in fair condition, and 38% were in poor condition, a worsening from
2017. For algal bloom presence, measured as chlorophyll a, 46% of the 24 stations sampled were
rated as good, 25% as fair and 29% as poor, again, worse than 2017. For turbidity, 22 sites
sampled were rated as good, and two sites as fair. 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. We also note that
Hurricane Florence led to worsening of the water quality compared with 2017, as well.

SECTION B: PUBLIC EDUCATION AND OUTREACH

1. Objectives f or 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 f or 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
and/or stressors
The permittee shall maintain a description of the target
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
industrial/commercial issues
The permittee shall describe issues, such as pollutants, likely
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 plan including goals, objectives, target
pollutants, sources, and target audiences is included in the Public Education & Outreach Appendix of this
report.

The plan defines the origin and sources for each pollutant and includes suggested outreach messages and
strategies for reaching target audiences. Staff regularly uses this information as a guide for planning,
implementing, and evaluating outreach and education efforts throughout the city. The plan is updated and
modified as pollutant sources, target audience demographics, public awareness, water quality, funding, and
other program variables change over time. The plan was recently updated in 2019.

e. Informational Web Site The permittee shall promote and maintain, an internet web site
designed to convey the program’s message.

Accomplishments:

22

Staff continued to update the Stormwater Services website with relevant stormwater
and program content such as the annual Stormwater Watch Newsletter, Canines for
Clean Water photos, news and events, UNCW water quality report, and more.
www.wilmingtonnc.gov/stormwater

f. Distribute public education
materials to identified target
audiences and user groups.
The permittee shall distribute stormwater educational material to
appropriate target groups (ex.: schools, homeowners, and/or
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:
Direct education and materials were provided to 37 apartment
complex managers within a 1-mile radius of UNCW to address the
issue of fecal coliform pollution detected via water quality
monitoring near campus. A comprehensive database of the apartment
complexes was developed and included direct contact and inquiry
resulting in data about pet waste policies, number of pets, DNA
tracking, management company, issues/concerns at each complex.

A pet waste toolkit was developed containing resources for supplies,
city ordinances, successful pet waste management programs at other
complexes, free signage, etc. The Stormwater Compliance Officer
worked with us to include a letter in the toolkit addressing the city's
pet waste ordinance and fines and serve as a contact for apartment
complex managers should they have further questions. The toolkits
and signage were delivered in person to each apartment complex. As
a result, several managers requested additional signage and are
interested in having us participate in future pet events on their
properties.

This year’s annual Stormwater Watch newsletter was mailed to 40,000+ city residents and contained articles
highlighting pet waste/fecal coliform pollution, Canines for Clean Water Program, Heal Our Waterways
Program, and the UNCW water quality monitoring report of creeks and lakes that fall within the city limits.
State classification and rating data is also included in the water quality information for each creek.

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 2018-2019,
the majority of presentations occurred in the spring due to Hurricane Florence. This year we served 67
classes and 2,200+ students. The interactive presentations focus on watersheds, water quality, non-point
source pollution and solutions, and stewardship. Cape Fear River Watch, New Hanover Soil & Water
Conservation District, and the City of Wilmington Stormwater Services use trained and certified instructors to
deliver presentations. An instructor training was conducted for new and veteran instructors in October 2018.

23

Anonymous teacher feedback was positive this school year, with some suggestions for technology
incorporation.

Stormwater education staff presented and/or exhibited at Isaac Bear Early
College, the MLK Center Summer Camps, Cape Fear Academy, Earth Day
Festival, and UNCW Environmental Policy classes and field trips.

Fall and Spring coordinated media campaigns aired on digital billboards, radio,
television, media websites, and digital and mobile platforms. In a review of
post-campaign stats with media agencies, message formats on digital and
mobile platforms outperformed the national average by 10 times.
For example, the fall stormwater campaign from Sept – November 2018 on
WECT/NBC digital and mobile platforms:
 Total ads viewed in Fall Campaign: 341,568
 .71% engagement rate (national average is 10%)

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.wilmingtonnc.gov/reportstormwaterpollution.

Hotline/web reports are routed to the Stormwater Code Compliance Officer
who tracks, investigates, and responds to each hotline report. The hotline and
online reporting webform are advertised on the City’s cable TV channel and
via the stormwater website, citywide newsletters, public presentations and
displays, large educational magnets on stormwater vehicles, and promotional
outreach items including cups, pens, reusable bags, magnets, and other
giveaways to the public.

To summarize hotline/web reporting activity this past year:
17 calls were placed to the City’s Stormwater hotline, 18 online hotline
webform reports were submitted, and 388 emails and 65 calls were directly
received by the Compliance Officer related to stormwater violations. The
nature of the hotline reports are found in the Enforcement section of the
Appendix.

24

h. Implement a Public Education
and Outreach Program.
The permittee’s outreach program, including those elements
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 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.

Assessment of Program Implementation
The city’s stormwater outreach and education program continues to implement a variety of innovative
activities and programs that meet or exceed the minimum requirements of our NPDES permit to educate the
community about stormwater runoff pollution/solutions and inspire action and behavior change. These
extensive activities can be viewed in the Appendix

25

SECTION C: PUBLIC INVOLVEMENT AND PARTICIPATION

1. Objectives f or Public Involvement and Participation

Comply with State and local public notice requirements when implementing a public involvement
and participation program.

2. BMPs f or 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
involvement program
The permittee shall include and promote volunteer opportunities
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 public involvement and
participation activities, as well as public education and outreach services. Both agencies sign an annual
contract with the City which specifies deliverables that help Stormwater Services fulfill 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 encourages citizens to become involved in stormwater outreach, education and
involvement efforts.
Services performed by CFRW & NHSWCD include volunteer watershed clean-ups, volunteer creek
monitoring, educational presentations for schools and the community, participation in the Lower Cape Fear
Stewardship Awards program, a monthly rain barrel sale, volunteer creek monitoring, volunteer storm drain
marking, 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 services performed. The cumulative year-end progress 4th quarter progress report for each agency is
included in the Public Involvement and Participation Appendix of this annual report.

26

b. Mechanism for Public
involvement
The permittee shall provide and promote a mechanism for public
involvement that provides for input on stormwater issues and the
stormwater program.

Accomplishments:
Hurricane Florence impacted the Wilmington-area beginning with landfall of the storm on our coast in
September 2018. Much of the fiscal year (FY18/19) was spent dealing with response to the hurricane. Many
slated in-house and capital improvement projects were put on hold in order to respond to the damage that
occurred to the stormwater system because of the storm. Therefore, public meetings and project notices for
“regular” projects largely did not occur this year.

Immediately after the storm, over 250 calls were placed to the city’s emergency center regarding stormwater
impacts including drainage, flooding, sink holes, etc. Since the storm hit, city staff have met with local
residents and FEMA to assess infrastructure and repairs to the stormwater drainage system.

A Hurricane Florence Recovery Map was posted to enable citizens to view and search the status of repair
projects.

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
www.wilmingtonnc.gov/reportstormwaterpollution.

Hotline/web reports are routed to the Stormwater Code Compliance Officer who tracks, investigates, and
responds to each hotline report. The hotline and online reporting webform are advertised on the City’s cable
TV channel and via the stormwater website, citywide newsletters, public presentations and displays, large
educational magnets on stormwater vehicles, and promotional outreach items including cups, pens, reusable
bags, magnets, and other giveaways to the public.

To summarize hotline activity this past year:
17 calls were placed to the City’s Stormwater hotline, 18 online hotline webform reports were submitted, and
388 emails and 65 calls were directly received by the Compliance Officer related to stormwater violations.
The nature of the hotline reports are found in the Enforcement section of the Appendix.

27

Assessment of Program Implementation
The City has continued to partner with contract agencies to implement public education, involvement and
participation activities. These annual, contractual agreements have resulted in activities and events that
involve the public and community to a large degree.

With Hurricane Florence impacting our area, public meetings and notices for capital improvement projects
and in-house projects were delayed this year due to hurricane response.

28

SECTION D: ILLICIT DISCHARGE DETECTION AND ELIMINATION (IDDE)

1. Objectives f or 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. Infor m 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 f or 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.

BMP 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).
The City will continue to review its ordinance annually to make sure we are providing adequate legal
authority.
b. Maintain a Storm Sewer System
Base Map of Major Outfalls.
The permittee shall maintain a current map showing major
outfalls and receiving streams

29

The City continues to maintain and update a base map of major outfalls and receiving water bodies.
Outfalls are classified and added to the GIS dataset as mapping of the City MS4 proceeds. Additionally,
the City has made significant improvements to the GIS mapping of watershed boundaries using the best
available data. At this time, approximately 95.4% of the City has been mapped as part of its stormwater
inventory. This percentage demonstrates an increase from 93% last due to a concerted effort to map the
remaining portions of the City that are still unknown. A continued effort to map the remaining portions of
the City will be a goal in the next few years.

Stormwater Inventory Mapping was completed this past reporting year in the Burnt Mill Creek
Watershed. Burnt Mill Creek Watershed, an impaired water body as noted on the 303d list, was noted in
the previous year’s report as an area to be prioritized. This area is an older part of the City where the
stormwater inventory is not fully known. The new stormwater inventory data will help staff to understand
where current drainage systems are located as well as provide data to help in future planning for the
requirements for our NPDES Phase II permit. Future locations are shown below on the map.

30

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.

Accomplishments:
The City continues to use its data collection procedures established during the previous reporting years. The
process has streamlined time spent at each structure while providing copious information that can be exported
into a spreadsheet for reviews. Several Stormwater Services staff utilize the field procedures in order to
provide additional assistance and scheduling flexibility throughout the next year. Dry weather flow
procedures are included in Appendix D. City Staff will be reviewing the existing IDDE Program Manual in
the next year to address changing NPDES requirements.
The dry weather flow web map, when accessed through the Collector app (as shown below), allows staff to
collect relevant data while in the field, including photographs, using only a tablet or smart phone. The
inspector is able to enter the data, including date and time, color, odor, turbidity and other relevant
characteristics of the location into the preformatted database. The data are then uploaded to the City servers
in real time, allowing office staff to see the data and develop reports without the need for cumbersome data
transfer routines or post processing.

The number of outfalls investigated this reporting year was severely hampered by Hurricane Florence
(Appendix D). Staff time and resources were directed to emergency operations for several months after the
storm, and repairs took upwards of a year. This took away from normal scheduling of dry weather flow
investigations. City Staff have been discussing how to ramp up the number of investigations for the next
reporting year. With the addition of Stormwater interns and a new Code Compliance Officer position, Staff
should be able to increase investigations. The plan in the upcoming years is to get all outfalls on a 2 year
rotation with 50% of the outfalls in one year and the remaining 50% in the second year. The justification for
this rotation was due to the time it takes to do investigations in the coastal plain. A single dry weather flow
investigation sometimes takes as much as a half of day in some instances due to tidal influence and
groundwater intrusion into the piped drainage system, which is very common. In order to determine where
flows are originating, staff must follow main trunk lines and lateral lines for blocks to eliminate sources of
flow, which is very time consuming when groundwater infiltration is involved.

d. Investigate sources of identified
illicit discharges.
The permittee shall maintain, and evaluate annually written
procedures for conducting investigations of identified illicit
discharges.

Accomplishments:
The City has continued to utilize its Illicit Discharge Detection Elimination (IDDE) Policy and Procedures
Manual document. 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 continues data input and documentation through Intelligov, our data management system. All details
of incidences are reported are entered from the start of an incidence until the investigation until is closed. This
documentation into Intelligov 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.

31

The City continues to look at upgrading all data management systems throughout the organization.
The schedule to begin rolling out the new systems for certain departments may begin in 2020.

e. Track and document investigations
illicit discharges
The permittee shall track all investigations and document the
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 address illicit discharges in the stormwater system and to protect public water under its
Ordinance. This Ordinance change went into effect on November 1, 2009. The City continues to update the
Illicit Discharge Detection Elimination (IDDE) Policy and Procedures manual as the program evolves. The
purpose of this document is to provide standards for protocol, field guidance and information for the effective
and efficient implementation of the Illicit Discharge Detection and Elimination (IDDE) Program. We
continue to update as procedures change and become more efficient for data collection and reporting into the
City’s tracking database Intelligov.

The City also continues to utilize its process for collecting data for dry weather flow monitoring during this
reporting period.
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 wasn’t able to conduct training for staff this year due to the impacts from Hurricane Florence and
time and resources being allocated to repairs and cleanup efforts. The City has training scheduled for July
and November 2019 which will be documented in next year’s report.

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 Education Program Manager and staff do an outstanding job of providing the public information through
education regarding illegal discharges. One of these ways is through The Enviroscape Watershed Education
Program. The Enviroscape Watershed Education Program has been integrated into the 8th grade curriculum
since 2005. As a result, the program reaches all 8th grade science classes in New Hanover County Schools,
this year serving 27 classes and 2,200+ students
Direct education and materials were provided to 37 apartment complex managers within a 1-mile radius of
UNCW to address the issue of fecal coliform pollution detected via water quality monitoring near campus.

This year’s annual Stormwater Watch newsletter was mailed to 40,000+ city residents and contained articles
highlighting pet waste/fecal coliform pollution, Canines for Clean Water Program, Heal Our Waterways
Program, and the UNCW water quality monitoring report of creeks and lakes that fall within the city limits.
State classification and rating data is also included in the water quality information for each creek.

32

Stormwater education staff presented and/or exhibited at Isaac Bear Early College, the MLK Center Summer
Camps, Cape Fear Academy, Earth Day Festival, and UNCW Environmental Policy classes and field trips.

The City’s Public Services Code Enforcement Officer also works hard to educate the public on Illicit
Discharges through educational material and flyers when making site visits and meeting with the public
during investigations.

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.

Hotline/web reports are routed to the Stormwater Code Compliance Officer who tracks, investigates, and
responds to each hotline report. The hotline and online reporting webform are advertised on the City’s cable
TV channel and via the stormwater website, citywide newsletters, public presentations and displays, large
educational magnets on stormwater vehicles, and promotional outreach items including cups, pens, reusable
bags, magnets, and other giveaways to the public.

To summarize hotline activity this past year:
17 calls were placed to the City’s Stormwater hotline, 18 online hotline webform reports were submitted, and
388 emails and 65 calls were directly received by the Compliance Officer related to stormwater violations.
The nature of the hotline reports are found in the Enforcement section of the Appendix.

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 Intelligov 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 2018-2019 there were no repeat
offenders 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. Unmapped areas will be surveyed and added to our database. The City will continue
with its goal for getting the remaining areas mapped, outfalls added as necessary and updating any relevant
information.

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.

33

Employee training will be scheduled on a 2 year rotation between Stormwater field crews, Parks and Rec. field
crews, Solid Waste field crews, Streets field crews and Engineering Inspectors. The City will evaluate the
effectiveness of the training by tracking the number of complaints initiated by City Staff.

Enforcement of IDDE violations will continued to be tracked through the City’s management system.

34

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.

35

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
compliance.
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

36

the City’s Phase II permit and to bring the ordinance into compliance with the Coastal
Stormwater Legislation.
Currently the City is looking at making updates to its Land Development Code. Planning for
these changes has been occurring during the last year with City staff meeting weekly to review
sections within the Code. Tentatively, the draft of the revised Code should be available to
review and discuss in spring 2020.
b. Strategies which include
Stormwater Control Measures
(SCMs) appropriate for the MS4
Maintain strategies that include a combination of structural
and/or non-structural SCMs implemented in concurrence
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 three P.E.s and one E.I. 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
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

37

Accomplishments:
The City continues to conduct site plan reviews utilizing the City’s Land Development Code in
order 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-
construction structural stormwater
control measures
The permittee shall maintain an inventory of projects with
post-construction structural stormwater 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.

Engineering and Stormwater Staff are planning to incorporate the spreadsheet data into a GIS
application in order to improve the database of permits and help with future permit renewals.
This planning should begin in Fall of 2019.

e. Deed Restrictions and Protective
Covenants
The permittee shall provide mechanisms such as recorded
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 (reproducible mylar) for all stormwater management facilities
certified by an authorized registered professional must be provided to the City for permanent
record.
When deemed necessary by the City, an access agreement in a form approved by the City
attorney, granting the City and its agents and representatives adequate and perpetual access to
the facility and sufficient area for inspection and maintenance, if necessary, by the City, its
agents and representatives. Said agreement shall be filed in the New Hanover County Registry,
at the expense of the applicant, and shall bind all subsequent owners and assigns of the facility
and of the property on which the facility is located.
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

38

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 long-term inspection and
maintenance of Stormwater Control
Measures (SCMs).
The permittee shall implement or require an inspection and
maintenance plan for the long-term operation of the SCMs
required by the program. The inspection and maintenance
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 O&M requirements and plans of the State through the review process.

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 semi-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

39

Stormwater SCM Inspection and Maintenance Certificate offered through NC State’s
Biological and Agricultural Engineering Department (certification #182). Recertification
occurred on January 31, 2017. An inspection summary is included in Appendix F.
The City continues to review and update its manual for all O&M plans for known City owned
and/or maintained SCMs under their respective NCDWQ stormwater permits. This manual
provides access to SCM schedules for O&M and permit renewal dates.
City Stormwater field staff who work on the maintenance of City owned SCMs will be getting
their SCM Inspection and Maintenance certifications through NC State’s program in the
Fall/Winter 2019. Approximately 5 staff members are signed up to take the certification class.

h. Educational materials and training
for developers
The permittee shall make available through paper or
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.

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 in order to meet the requirements of the City’s Phase II permit Ordinances will be
evaluated annually to determine if modifications are needed.

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 provisions 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 f or 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
owned or operated facilities
The permittee shall maintain, a current inventory of facilities and
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 continues to keep an inventory of its known facilities with the potential for generating polluted
runoff. Sites are identified by location, type of facility and potential pollution sources. These sites were
evaluated to determine if further implementation of pollution prevention measures and BMPs could help
to minimize current on-site procedures and equipment from potentially polluting the surrounding
stormwater systems. Although no formal SPPP was required for each individual site, the City opted to be
proactive in reducing the potential for contaminants and other pollutants that could leave the sites. Site
SCM recommendations are implemented as needed at the locations when site conditions change (i.e.,
renovations, equipment changes). Three Parks and Recreation locations will be evaluated in the coming
reporting year. This process was delayed in this reporting year die to Hurricane Florence and its major
impact on the City.

The City currently has a Spill Prevention Control and Countermeasure plan (SPCC) for the Operations
Complex and a separate Stormwater Pollution Prevention Plan (SPPP) for the Fleet Maintenance
building located within the complex. A SPCC is also in place for the Police Headquarters location.

b. Inspection and Maintenance
(I&M) for municipally owned
or operated facilities
The permittee shall maintain and implement, evaluate annually
and update as necessary an Inspection and Maintenance (I&M)
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.

42

Accomplishments:
Currently, The City relies on a SPCC plan and a SPPP for the Operations Complex and Fleet
Maintenance building. These plans focus on the activities at Fleet Maintenance and also preventive
inspections at the City’s fueling islands, (2) 10,000g fuel tanks and the 6 generators on site. An
additional SPCC for the Police Headquarters addresses inspections for their fue ling island and backup
generator as well. Analytical and qualitative monitoring of the outfall per the requirements of the SPPP
and General Permit (NCG08000) for Fleet Maintenance indicate parameter levels well below benchmark
values.

Stormwater staff meets annually with appropriate site managers to ensure that proper documentation of
the SPCC and SPPP is occurring. Stormwater staff evaluates any changes or modifications that may have
occurred to the site within the year and works with the site managers to address any operation and
maintenance practices that can be improved.

The City has begun implementing an O&M plan for all of its locations where oil/water separators are
present. The Buildings Manager has begun to budget for getting these locations on a regular quarterly
schedule for inspection and maintenance in order to ensure their l ongevity and functionality. The O&M
plan could not make it into the 2019 -20 budget but is set for the following budget year. However, if
funds can be appropriated for the 2019-20 calendar year through other means, then securing a contractor
may happen sooner.

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 also ensure docume ntation is occurring within the plans.

Stormwater staff and the Public Services Safety Specialist have implemented the requirement for
appropriate staff to complete training courses regarding spill prevention and small spill cleanup.
Eight (8) Fleet Maintenance Staff completed training for the prevention of spills and small spills cleanup.
During the upcoming reporting year, Stormwater Field Supervisors will be included in the same training.

Planning has begun for the 2019-20 reporting year to bring all relevant personnel into a field training
session at all necessary locations . . This process was delayed in this reporting year du e to Hurricane
Florence and its major impact on the City.

d. Streets, roads, and public
parking lots maintenance
The permittee shall evaluate existing and new BMPs annually that
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.

43

In reporting year 2018-19, street sweepers swept 7,949 curb miles while collecting sediment, vegetation
and trash potentially diverted from the stormwater sewer system. The amount of debris tonnage could not
be calculated this reporting year due to the scale house being inoperable. The City will be phasing out the
scale house due to costs and constant repairs so the amount of debris will need to be calculated by other
methods. Currently, City Stormwater Staff are discussing procedures to estimate the amount of cubic
yards collected daily and report quantities in that manner. Staff will be conduction discussions in Fall
2019.
In fiscal year 2018-19, stormwater crews conducted hand maintenance of 173,011 feet of ditch, 19,657
linear feet of ditch by mechanical methods, cleaned 66,916 linear feet of pipe, and removed blockages and
cleaned 8,468 drainage inlets and manholes thus reducing debris, sediment, vegetation and trash
potentially diverted from being discharged into our receiving waters.
The City has been a member of the Urban Stormwater Consortium of the Water Resources Research
Institute of the University of North Carolina. This group funded and completed a study at nutrient
loading in urban areas. One of the conclusions from the study indicated that urbanized, downtown areas
of cities were the highest contributors of gross solids in catch basins. The study recommended that street
sweeping should be conducted more frequently in these areas to help minimize the solids from entering
the catch basins. Currently, the City follows this practice by conducting routine street sweeping in the
Central Business District, 7 days/week to help prevent and reduce the amount of gross solids from
entering the downtown stormwater system.

The City continues to further look at all of its field maintenance activities to determine if improvements
to water quality can be incorporated.

e. Inspection and Maintenance
(I&M) for municipally -owned
or maintained catch basins and
conveyance systems
The permittee shall maintain and implement an I&M program for
the stormwater sewer system including catch basins and
conveyance systems that it owns and maintains.

Accomplishments:
The City currently has a program for the operation and maintenance of all City owned structural BMPs,
storm sewer system, and street sweeping. This program includes repair, inspection and maintenance of all
City owned right of ways and officially accepted easements. This information was previously included in
this report under Operations/Maintenance – Yearly Maintenance Activities Table on page 10 .

f. Identify structural stormwater
controls
The permittee shall maintain a current inventory of municipally-
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 of its City owned SCMs. The manual includes all
associated State DWQ stormwater permits, O&M plans, and site mapping in order 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 in order to keep the
BMPs in compliance.

44

g. I&M for municipally-owned or
maintained structural
stormwater controls
The permittee shall maintain and implement an I&M program for
municipally-owned or maintained structural stormwater controls
installed for compliance with the permittee’s post-construction
ordinance.

The I&M program shall specify the frequency of inspections and
routine maintenance requirements.

The permittee shall inspect and maintain municipally-owned or
maintained structural stormwater controls in accordance with the
schedule developed by permittee. The permittee shall document
inspections and maintenance of all municipally-owned or
maintained structural stormwater controls.

Accomplishments:
The City keeps and updates a BMP Manual for all its City owned BMPs. The manual includes all
associated State DWQ stormwater permits, O&M plans, and site mapping in order 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 in order to keep the BMPs
in compliance. Documentation occurs with every BMP site visit and maintenance activity.
The City plans to develop SOPs to address the frequency of inspections and routine maintenance
requirements for its SCMs during the next reporting year.

h. Pesticide, Herbicide and
Fertilizer Application
Management.
The permittee shall require that contractors are properly trained
and that all permits, certifications, and other measures for
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 20 certifications for Parks and Recreation staff and 4 certification
for Stormwater/Public Services staff.

i. Staff training The permittee shall implement an employee training program for
municipal employees involved in implementing pollution
prevention and good housekeeping practices.

Accomplishments:
Stormwater staff and the Public Services Safety Specialist review employee training annually through
our online courses and in house training regarding preventing spills and small spill cleanup for Fleet
Maintenance staff and the Spill Response Team per the City’s SPPP and SPCC plan. This training will
be an annual requirement for these employees. In addi tion, on site hands-on training for employees is
being discussed and planned by Stormwater staff and The PS Safety Specialist regarding spill
control/cleanup at the Fleet Maintenance site. In-house training was postponed this year due to Hurricane
Florence and its major impact on the City

45

j. Prevent or Minimize
Contamination of Stormwater
Runoff from all areas used for
Vehicle and Equipment
Cleaning
The permittee shall describe and implement measures to prevent
or minimize contamination of the stormwater runoff from all areas
used for 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. 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.
Small engine repair (line trimmers, blowers, chain saws, compacters, etc.) and cleaning for various City
activities occurs in individual departments maintenance garages. In the event of an accidental discharge,
the garages have drains located within the floor that connect to an oil water separator located on each site
within the Operations Complex. Other locations across the City’s operations facilities are planned to
be reviewed in 2020. Site recommendation plans will be determined as needed.
Assessment of Program Implementation
The City will continue to keep an inventory of its known facilities with the potential for generating
polluted runoff. Sites are identified by location, type of facility and potential pollution sources.
Inspection and Maintenance programs will begin to be implemented at locatio ns within 1-3 years and
documented annually. Site SCMs to help reduce the potential for pollutants to the stormwater system
will be evaluated and added or modified as needed.
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.
The City will be developing SOPs to address the routine inspections of its own SCMs in the next two
years.
Staff Training for City field crews will re-evaluated for content in the next reporting year.
The City will be conducting further inventories of all its facilities (outside of the current known locations)
to determine where small engine repair and vehicle maintenance (outside of the Fleet Maintenance
Facility) may be occurring. The City will be developing SOPs or other plans to address these locations for
SCMs that reduce potential sources to the stormwater system.

46

2. TM L 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.

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 maximu m 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.

• Describe the measures to be implemented within the remainder of
the permit term designed to achieve the MS4’s NPDES WLA and
to reduce the TMDL pollutant of concern to the MEP; and
• Identify a schedule, subject to Division approval, for completing the
activities.
g. Incremental Success The permittee’s plan must outline ways to track progress and report
successes designed to achieve the MS4’s NPDES regulated WLA and to
reduce the TMDL pollutant of concern to MEP within the watershed to
which the TMDL applies.
h. Reporting The permittee shall conduct and submit to the Division an annual
assessment of the program designed to achieve the MS4’s NPDES WLA
and to reduce the TMDL pollutant of concern to the MEP within the
watershed to which the TMDL applies. Any monitoring data and
information generated from the previous year are to be submitted with each
annual report.

4. If no MS4 NPDES regulated w aste load allocation (WLA) is specified in the TMDL

At any time during the effective dates of this permit, if a TMDL has been approved that does not
assign a WLA for the pollutant of concern to the municipal stormwater system, if there was no

Bradley & Hewletts Creeks Watershed Restoration Plan Accomplishments:
The Bradley and Hewletts Creeks Watershed Restoration Plan has continued
to make progress installing and promoting volume-reducing best management
practices (BMPs) to the public. Heal Our Waterways (HOW), which is the
branded name of the restoration plan, is becoming more widely known within
the watersheds. This is being accomplished through the use of strategically
implemented education and outreach efforts and successful networking and
promotion among stakeholders, community groups, and partner organizations.
As with previous years, two educational postcards were created and mailed,
this time in the winter 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 winter 2019
postcard educated recipients about how to reroute downspouts at home. The
spring 2019 postcard announced the 2019 Earth Day event and provided
directions to an online survey for the HOW program, which included a
Lowe’s $50 gift card giveaway.
Following the success of 2016’s downspout disconnection public service
announcement, starring local news anchor Jon Evans, the PSA was used again
as part of the overall “Downspout Disconnection” spring 2019 marketing
campaign. This PSA played whenever a HOW advertisement was clicked on
the WECT.com website. Web and digital platforms including video pre-roll
ads, mobile ads, and digital weather channel ads were also part of this
advertisement campaign. WECT.com is viewed by an average of 733,000
unique visitors per month and has 177,000 followers. HOW had over 463,000
ads served through WECT.
In addition to the PSAs, HOW utilized new online marketing features offered
by WECT. One HOW-related Facebook posted was sponsored to related zip
codes and users throughout the month, and one specific post announcing the
local rain barrel sale was posted on rain barrel sale day. The rain barrel sale
post received the most engagements (1,230 total) which contributed towards the overall engagement rate
being 4x higher than what WECT normally sees. The campaign also involved two “Homepage Takeovers” on
WECT’s website, one announcing the rain barrel sale date and one featuring details for Earth Day and
HOW’s rain barrel raffle.
To continue the “Downspout Disconnection” messaging, a digital billboard campaign promoting a similar
message also aired. Contracting with Lamar (formerly Fairway Outdoor), billboard locations were chosen
based on their proximity to Bradley and Hewletts Creeks. One billboard ran for a total of 28 days and two
billboards ran for a total of 14 days each, all with 8 seconds of air time per minute, 24 hours a day.

50

HOW also renewed its presence as an underwriting partner with local National Public Radio affiliate,
WHQR. This year, the campaign focused on benefits of rerouting downspouts at home and the availability of
HOW for presentations. Due to a financial system overhaul in February, the campaign was broken into two
sessions. The first ran in January 2019 and included 20 total announcements over 3 weeks. The second ran in
late spring for 8 weeks, with 4 announcements during drivetime each week. Each week, WHQR reached
about 40,000 listeners in the Wilmington Designated Market Area.
HOW staff continued its presence this year at Wilmington’s Earth
Day Festival. As with years past, the event was well-attended,
attracting 5,000+ visitors. Promotional items and program
materials were distributed at the event, and a drawing for a rain
barrel giveaway was conducted. Along with providing educational
opportunities, these events also help gage outreach and advertising
effectiveness. During the Earth Day Festival, several individuals
stated that they had heard about the rain barrel raffle, likely due to
WECT’s homepage takeover. Additionally, 21 people joined the
mailing list at the Earth Day event in order to receive more
information about how to get involved.
City Communications and HOW staff continue to maintain a visually appealing website. The “Take Action”
page and homepage were revamped to be more user friendly and motivational. In 2019, the Heal Our
Waterways home page has received 3,004 unique views. This is up from 1,620 the previous year. The Heal
Our Waterways social media presence has also increased, with Twitter and Facebook followers of 224 and
198, respectively.
Heal Our Waterways ended one grant this year and continued
two more. The EPA 319 Bradley & Hewletts grant with the
North Carolina Coastal Federation ended in March 2019. The
Green Infrastructure Center Tree grant and the EPA 319 grant
in partnership with the North Carolina Coastal Federation and
the University of North Carolina at Wilmington both
continued.
The NCCF Hewletts & Bradley Creek 319 Grant ended in FY 18-19. Grant team partners met to discuss the
status of implementation and volume reduction summaries. Through the grant, permeable pavement was
installed at both the New Hanover County Arboretum and Waterman’s Brewing. The Wrightsville Beach
Animal Hospital also received an infiltration basin and several homeowners in the Palmetto Point
neighborhood received rain barrels.
City Planning, Stormwater, and Parks Divisions met several times in FY 18-19 to discuss the results of the
Green Infrastructure Center (GIC) Tree grant. The citywide study looked at tree canopy and opportunities to
use trees for stormwater management in the city. Heal Our Waterways and Stormwater education examined
each of the recommendations and supplied brief summaries for how they could be implemented into current
programs. The City Arborist will be presenting the summaries, as well as input from other Divisions, to City
Council in the near future.

51

The Lynnwood/Glen Meade EEG grant is complete, but a new sign was placed at the site in winter 2019. The
sign discusses the project scope, design, and partners and provides an educational resource to the
neighborhood about stormwater.
In January 2019, the North Carolina Coastal
Federation and University of North Carolina-
Wilmington EPA 319 grant got underway. As a part
of grant match and to bring awareness to the grant,
Heal Our Waterways provided funding for additional
rain gardens on campus. Two rain gardens were
installed in front of DePaolo Hall, and one segmented
garden was installed near the DeLoach Hall parking
lot. Over 20 volunteers helped to plant the rain
gardens with native plants in June 2019. HOW also
purchased five cisterns that will be used around the
greenhouses and other applicable areas on campus for
water reuse. The total volume reduction for the 319
UNCW grant this year was 5,425 cubic feet in
Bradley Creek.
New Hanover Soil & Water Conservation District
(NHSWCD) was once again granted a contract (HOWBMP) with the city to install BMPs on private
properties in the watersheds. HOWBMP produced six total installations this year, and identified interested
potential participants for next year. Of this year’s participants in the program, all homeowners were in the
Hewletts Creek Watershed. Two of the homeowners had two projects installed on their properties. The total
volume reduction from the HOWBMP program this year was 337.5 cubic feet.
HOW staff continues to track BMP 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 BMPs within the two target watersheds, and continues to
be a key factor in HOW’s progress, both in scope and accuracy. All of the 319 and NCCF grant projects,
HOWBMP projects, and city-wide rain barrel sale data was recorded for the 18-19 FY.
HOW also dedicated time towards stakeholder
outreach this year. To gage perceptions regarding
water quality, stormwater solutions, and potential
barriers, staff distributed a survey to watershed
residents via a postcard mailer. During the month of
March, HOW was also present at several breweries
and local businesses in the area to conduct in-person
surveys. The in-person surveys generated more
conversation, while the online survey provided
more room to write in the comment fields. To
encourage participation, rain barrels and a $50
Lowe’s gift card were provided as prizes.
Finally, HOW established collaborative
relationships with the NHC Arboretum, Airlie Gardens, and the Wilmington Farmer’s Market at Tidal Creek.
HOW has been able to visit their events with raffles and educational displays. These partnerships are a great
avenue for continuous community outreach and for keeping interest in doing work with partners.
Annual Assessment & Evaluation of Plan Implementation:

52

This year the HOW program implemented multiple successful
projects, despite several hurdles and shortened timelines. The
HOW program went without a dedicated watershed coordinator
during fall of 2018. An interim coordinator was hired in
December to resume implementation of the program. Hurricane
Florence also caused multiple setbacks for finalizing contracts
and setting up projects. The City also switched financial systems
during February and March, which prohibited city spending for
several weeks.
Despite these hurdles, the HOW program accomplished several
large projects. The survey and outreach events engaged the
community and local businesses. Several rain gardens were put into the ground at UNCW, which will help
reduce pollution entering Bradley Creek, improve drainage problems at UNCW, and act as examples for
UNCW and the local community. HOWBMP also had a large number
of participants and is already geared up for multiple new applicant site
visits to kick off the new fiscal year.
This was a year of growth and reflection through community
engagement. The feedback from residents will be extremely helpful for
guiding educational materials and outreach strategies in the coming
year. Continuing the grant with UNCW and NCCF will also provide
more opportunities for collaboration and potential volume reductions
for the target watersheds.
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.

HOW continued the winter and spring watershed mailers again this year to support Action 1-2 and 1-4. The
winter mailer provided directions for rerouting downspouts and the spring mailer announced the Earth Day
event and an online survey. Both were mailed to over 20,000 residents within the target watersheds.
All of the media partnerships also continued this year for educational messaging to support Action 1-4. HOW
partnered with WECT, WHQR, and Lamar Billboards to advertise how to reroute downspouts at home and
bring awareness to the Heal Our Waterways program. Several residents mentioned they had heard the
advertisements on WHQR, and multiple residents came to the Earth Day event because they had heard about
the rain barrel raffle. This feedback solidifies the benefit of continuing partnerships with local news media
into the coming year.
Another existing program with continued success this year is the contractual partnership with New Hanover
Soil and Water Conservation District (NHSWCD), called the HOWBMP Program, to support Action 1-2.
There were a total of 6 projects this summer between 4 homeowners. The volume reductions were smaller
than in previous years, but the number of installations were greater. The program continues to spread through
word-of-mouth and conversations at local events throughout the year. HOWBMP is already looking forward
to 9 site visits in the coming year and potentially more through continued outreach.
Outreach throughout the year not only raised awareness for HOW programs, but also promoted the use of
Low Impact Development on private properties, also in support of Action 1-2. Each HOW outreach event
included an educational table with information from a “Smart Yards” booklet drafted by the North Carolina
Coastal Federation. The booklets are now also sponsored by HOW and have been an invaluable resource at
events. Homeowners gladly take the booklets to find out what they can do at home. Since HOW funding is
only applicable to target watersheds, having these booklets on hand helps to reach people that live outside of
the watersheds and may want to implement their own projects at home.
To support Action 1-6, the City of Wilmington “Canines for Clean Water” program was present at several
events and continued its campaign to encourage homeowners to pick up after their pets to reduce bacteria
amounts in stormwater. The City’s Code Enforcement Officer also continued to put out educational signage
and followed up on pet waste complaints from residents.

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. In his 2018/2019 report, Dr. Mallin wrote that
at four stations on Hewletts Creek, all stations “well exceeded 200 CFU/100mL for a poor rating for this
pollutant parameter [fecal coliform]”.
This plan objective concentrates heavily on the classification of local waters and the appropriateness of
current classifications considering today’s conditions. Ongoing issues regarding the proper classification of
some waters and the possibility of a reassessment and overhaul of the classification criteria by the State of
North Carolina have delayed staff in addressing this objective for the last several years. As with years past,
there has been no change in classification this year. While not critical to the success of the plan at this stage,
as the plan continues to gain traction and improve water quality, reclassification will become a more pressing
concern.
Objective 3: Reduce the transport of bacteria from land to water by reducing and tracking volume
reduction:

Both Action 3-1 and Action 3-2 had progress this year at record levels. The total number of installations in
both watersheds was the most it has been since the program’s inception in 2012. This was accomplished
through grants, community partnerships, local rain barrel sales, and the HOWBMP contract program.
The North Carolina Coastal Federation’s (NCCF) grant for stormwater retrofits on UNCW’s campus was an

55

open opportunity for additional grant match projects. HOW was able to fund three additional rain gardens,
totaling 5,271 cubic feet of reduced stormwater volume into Bradley Creek. These projects, with the addition
of 5 305-gallon cisterns funded by HOW for UNCW, and projects installed by NCCF as part of the 319 Grant
“Implementing the Bradley and Hewletts Creek Watershed Plan”, pushed the program almost three-fold past
its internal performance measure in the strategic plan of 0.15 ac ft. of stormwater volume reduction at a final
total of 0.41 acre feet.
HOWBMP installed retrofits in the Hewletts Creek Watershed this year. There were six total projects
between four homeowners. For one cistern, four rain garden, and one wetland installations, the volume
reduction was 337.5 cubic feet. However, the total number of installations in the Hewletts Creek watershed
was far greater due in part to the NCCF 319 grant dedicated to the implementation of the watershed
restoration plan. The final results for Hewletts Creek in the 18-19 FY are 21 total installations and a final
stormwater volume reduction of 470.5 cubic feet.

During the 18-19 FY, the Bradley and Hewletts Creek watersheds has recorded a record number of total
installations within a given year since HOW was established in 2012. Part of this success is attributed to
establishing stronger communication with partner agencies doing similar work within the watersheds and
sharing volume reductions to include in the City’s GIS Atlas, which was finalized the previous year. This tool
has been instrumental in tracking locations of projects, contact information, and has even helped partner
agencies with their grant reporting. The Atlas tool will continue to play a vital role in the HOW program’s
progress and Action 4-1 will be continued in the coming year.
Action 4-9, 4-10, and 4-2 all played a role during the design and implementation of stormwater retrofits at
UNCW this year. HOW and the Chief Sustainability Officer at UNCW worked together to identify suitable
areas for rain gardens and cisterns to support the UNCW Master Plan. There has been progress on the plan
this year, with stormwater as a heavy focus area, but the final details of the plan are still not readily accessible
to HOW staff. However, HOW was a presence at the UNCW Sustainability Council meetings and provided a
brief summary of the watershed restoration plan for Bradley Creek to a core group of decision-makers.
Stormwater was referenced multiple times as an area of high concern and, overall, the reception to potential
retrofits has been received well. Several professors and staff have even participated in the brainstorming
sessions for which areas on campus needed attention. Not all of the locations were addressed this year, but the
ideas are prepared for the coming year of grant work and the UNCW community is highly interested in seeing
the work move forward.
HOW has also participated in several workgroups this year, two of which support Action 4-4. The Green
Infrastructure Center (GIC) recently wrapped up its grant for the City of Wilmington and a City staff
workgroup (including HOW) has reviewed the feasibility of the recommendations. The grant focused on the
natural stormwater treatment trees can provide and identified locations within city limits that could benefit
from more tree canopy. They also reviewed city codes and ordinances and recommended actions that could
help to promote tree retention. This year also involved conversations about how to replace trees lost during
Hurricane Florence, as the hurricane caused a significant amount of tree damage. Several of the
recommendations supported the mission of the HOW program and will be summarized for City Council to
review. In addition to the City’s efforts, New Hanover County also began a tree workgroup to examine tree
policies county-wide. This group has a greater variety of participants from several local environmental and
government organizations. The workgroup just began this year and is narrowing down its mission statement
and goals. More actions will be identified this coming year as the group transitions from planning to
implementation.

Action 5-6

Work with UNCW on retrofit
projects
Years 1 – 5 grants, capital improvements
City of Wilmington - Stormwater
Services; UNCW, NCCF

Partnerships are one of the greatest strengths of the HOW program and contributed to the record number of
installations since the inception of the program. HOW continued its partnerships with local news media
outlets (WECT, WHQR, and Lamar Billboards), the New Hanover County Soil and Water Conservation
District, North Carolina Coastal Federation, University of North Carolina-Wilmington, NC State University –
Cooperative Extension, and members of the Wilmington Tree Commission. A multitude of new partners were
identified through the spring outreach campaigns within the watersheds. The Wilmington Farmer’s Market at
Tidal Creek Co-op, New Hanover County Arboretum, and Airlie Gardens have all been vital partners for
reaching local citizens. Several breweries in the area also expressed interest in the program, including
Wrightsville Beach Brewery and Waterman’s Brewing, and allowed educational tables during service hours.
In accordance with Action 5-1, HOW ran an intensive outreach campaign in spring 2019 using partners
within the watersheds to establish locations for educational booths. In-person surveys are typically difficult to
implement, but HOW had a total of 61 in-person survey participants thanks to the help of local businesses and
organizations offering space at their events. There was also an online version of the survey which had 207
participants.
The ongoing partnership with the NC Coastal Federation continues to fulfil Action 5-2, securing 319 grants
for retrofits within both target watersheds. The 319 grant for UNCW has already seen tremendous success for
Action 5-6 with the installation of three rain gardens and five cisterns. More work is planned this coming year
for parking lots on campus.
The UNCW 319 grant also provided opportunities to implement Action 5-1. HOW participated on UNCW’s
sustainability council, provided a presentation to decision-makers about the mission of the grant, and led a
volunteer planting date that gave volunteers hands-on experience with implementing stormwater solutions.
Objective 6: Measure success and adapt plan based upon results:

Water quality is still being closely monitored by UNCW, in accordance with Action 6-2. The most recent
report, published in April 2019, shows that fecal bacteria are still a concern in both creeks. Though one
station in Hewletts Creek was below state standards for recreation, it still exceeded the shellfish standard.
However, this year still had the most work completed of any year to date, so there is potential the results will
reflect improvements in the coming years if the program continues its upward progress.
To highlight the program’s progress through Action 6-1, the internal performance measure for Bradley Creek
was exceeded by 276%. Hewletts Creek did not meet its internal performance measure this year, but still had
21 total projects implemented. For private homeowners, larger stormwater retrofits are not always feasible so
volume reductions are often smaller in residential zones.
Awareness about the program continues to grow and participation is at an all-time high. Having achievable
goals will help to encourage continued expansion, more funding, and new innovative city programs to
champion the restoration of Bradley and Hewletts Creeks and push the City of Wilmington forward as a
leader in the mission to “Heal Our Waterways”.

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 water cannot penetrate, such as driveways, streets, parking
lots and rooftops, which prevent stormwater runoff from naturally soaking into the ground. 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 waterways.
In Wilmington, 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:
 17,601 storm drains, manholes, and other structures
 298 miles of pipes/culverts
 168 miles of open drainage (ditches and channels)
 38 acres of retention ponds, infiltration basins, and lakes including Randall Pond, Silver
Stream Pond, and Greenfield Lake
 110 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 Education and Outreach and Public Participation and Involvement is a component
of the City of Wilmington’s Comprehensive 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.

Public education and participation are essential tools to develop awareness, stewardship, and behavior
change for stormwater pollution issues in the City of Wilmington. By successfully reaching out to
citizens and businesses, we can reduce stormwater pollution in our local surface waters, preserving
them as a healthy and beautiful resource for our area.

As required by the NPDES Permit, the City of Wilmington’s Stormwater Plan must detail the City’s
outreach program for the five-year term of the stormwater permit. This document serves as the
Outreach and Education and Public Involvement Plan.

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. Approximately 22 sampling
sites assess the water quality of 10 of Wilmington’s creeks, as well as Greenfield Lake, and the Cape
Fear River. The findings are reported annually and serve as a valuable tool to gauge changes in water
quality in the area and guide our outreach/education/involvement efforts.

81

In addition, the City of Wilmington has established long-standing contracts with Cape Fear River
Watch & New Hanover Soil & Water Conservation District, which enables us to robustly satisfy our
BMPs and program goals/objectives.

CITY OF WILMINGTON’S OUTREACH & PARTICIPATION PROGRAM
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.

Our program educates citizens, businesses, and employees about the stormwater drainage system,
sources of stormwater pollution, the impacts of stormwater pollution on local waterways, and what
we can do as a community to prevent and reduce stormwater pollution through stewardship and
community action. Our program complies with the City of Wilmington’s NPDES federal
stormwater permit.

Our program is based on the principle 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.”

Best practice for developing outreach and education campaigns 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 Outreach Plan/Campaign

Once driving forces/goals/objectives are developed, identifying and analyzing the target audience
is one of the most important 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, etc.

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 think leaving pet waste on
the ground is a natural fertilizer, without realizing the negative bacterial impacts on water quality
and public health. Barriers should be addressed by your plan so that they are minimized or
removed and the benefits to behavior change are positively conveyed.

82

Packaging/formatting and distributing your campaign messages are vital to achieving success with
your campaign. The target audience should always be strongly considered when determining the
appropriate methods to reach them with campaign messages. Formats and distribution methods
range from mass media outlets, large events and field trips to more intimate formats such as focus
groups, neighborhood meetings and presentations, as well as 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 collaborations whenever possible, to jointly work on
outreach/education campaigns with other agencies that have similar goals.

Evaluating your outreach 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, is important for adapting your
program so that it is successful.
 Process Evaluations involve evaluating the campaign and components during
implementation (ie 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 (ie pre-and
post surveys, Google Analytics, water qualit y 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 (ie pet
owners cleaning up after pets, lawn care companies not blowing yard waste into streets,
etc.)

Our program addresses the following concepts as a basis for outreach/education efforts and public
involvement/participation:
 Awareness is the first step to 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 overall water
quality, aquatic habitat, shellfish harvesting, recreational water quality and access, and
drinking water resources, etc.
 Storm drains and drainage conveyances (i.e. swales, ditches, pipes, etc.) carry water directly to
local waterways without any treatment. Only rain should go down the storm drain.

83

 Impervious surfaces increase the speed and volume of polluted stormwater runoff entering the
stormwater drainage system and waterways.
 More impervious surfaces, means more degraded water quality.
 The quality and amount of polluted stormwater runoff entering local waterways can be
mitigated by installing BMPs (Best Management Practices). BMPs are any action or on-the-
ground practice that reduces the amount of stormwater and pollution flowing into waterways.
BMPs such as rain gardens, rain barrels, grassy swales, pervious pavement, and re-routing
downspouts to grassy areas allow stormwater runoff to soak into the ground and be cleaned
and filtered naturally.
 Plants, shrubs, trees, and other vegetation greatly reduce stormwater pollution by absorbing
and filtering stormwater runoff and preventing soil from washing away. Native vegetation is
especially important for decreasing fertilizer and pesticide use.
 Everyone can and should make a difference to improve and protect our waterways.
The program also addresses the six major pollutants that impact Wilmington’s waterways. These
pollutants can come mainly from nonpoint sources, however, we also address commercial and
industrial potential sources of water quality contamination.
1) Fecal coliform bacteria
2) Nutrients
3) Sediment
4) Chemicals
5) Litter
6) Vehicle Pollution

84

TARGET POLLUTANTS, SOURCES, AND AUDIENCES

The following table identifies 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, 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, City of
Wilmington Stormwater Services maintenance activities and data, education data, New Hanover
Animal Control statistics, and the Statewide Stormwater Survey of North Carolina residents.

This is a working document; therefore the goals and target pollutants will change over time based
on the target audiences’ knowledge and implementation of stormwater-friendly practices, as well
as changes in water quality data and trends. The pollutants, sources, audiences, messages, etc. are
described in the depth in the pages that follow.

TARGET POLLUTANT: FECAL COLIFORM BACTERIA (DOMESTIC AND WILD ANIMAL WASTE)
Fecal coliform bacteria are found in the feces of domesticated and wild animals, as well as human
waste. Stormwater runoff carries this bacterial pollution into local surface waters via the storm
drainage system. Bacteria contaminates waterways commonly used for recreational activities such
as swimming, fishing, and shellfishing resulting in swimming advisories and oyster beds closed to
harvest.

Pollutant Source:
Likely Residential Sources: Domesticated Animals, Stray and Feral Animals, Sewer Spills
Likely Commercial/Industrial Sources: Boarding Kennels, Veterinarian Facilities, Pet-Related
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. The primary source of this
bacterial pollution is canine and outdoor cat waste. Occasional sewer spills also contribute to
bacterial pollution, but this is an infrequent source of contamination.
Stormwater runoff washes bacteria, parasites, viruses, and nutrients from uncollected animal
waste directly into our waterways.
Fecal bacteria is an indicator bacteria. High levels of fecal coliform bacteria indicate the
potential for diseases and infections in humans upon contact. Pathogens such as roundworm,
salmonellosis, toxoplasmosis, E. coli, and gastroenteritis can be contracted via contaminated
water. These can also make other animals and wildlife ill as well.
Once in our waterways, these pathogens can cause shellfish bed closures, swimming
advisories, algal blooms, low dissolved oxygen levels, fish kills, 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.

87

Target Pollutant: FECAL COLIFORM BACTERIA (domestic and wild animal waste)
Key Outreach Messages:
 Messages should connect uncollected pet waste to water quality problems and human health impacts.
 Domesticated dog waste is a major source of bacterial pollution considering their population, daily defecation
rate, and bacterial production. Outdoor cats are also a major problem for these same reasons; steps should be
taken to control their waste as well.
 Bacteria can cause diseases and infections in humans and other animals.
 Pet owners have a responsibility to clean up after pets and dispose of the waste p roperly.
 Debunk barriers and myths to cleaning up after pets (i.e. it’s not fertilizer, its 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, etc).
 Pet owners should be aware of and abide by 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.
- Do not flush pet waste down the toilet (Cape Fear Public Utility Authority ordinance).
- Fines for non-compliance with the City’s pet waste ordinance are $250 per occurrence in the city
 Utilizing BMPs, such as rain gardens, rain barrels, and re-routing downspouts to grassy areas allows polluted
runoff and pet waste bacteria to soak into the ground and be cleaned and filtered naturally.

TARGET POLLUTANT: NUTRIENTS (FERTILIZERS, YARD WASTE)
Nutrients, such as nitrogen and phosphorus, enter our waterways via stormwater runoff that
carries fertilizers and yard waste into the storm drainage system. High nutrient loads cause algal
blooms, low dissolved oxygen levels, fish kills, and impaired aquatic habitats.

Pollutant Source:
Likely Residential Sources: Homeowners, Gardeners, etc. Landscaping Contractors
Likely Commercial/Industrial Sources: Landscapers, Turf Maintenance, Golf Courses, 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!
Lawn fertilization is one of the most widespread watershed behaviors by homeowners and
contracted 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. This debris can also wash into waterways via lawn/sprinkler
watering. This organic matter washes through the drainage system introducing nutrients and
pesticides into waterways.
Fertilizers and yard waste that end up in local surface waters impact aquatic ecosystems by
introducing 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 (i.e. fish) need to survive. This can lead to 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.

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 are 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 money spent on fertilizer.
 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 fertil izer 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.
 Landscapers/Property owners 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.
 Landscaping company employees should be trained on proper fertilization and yard waste disposal practices.
 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: SEDIMENT (SAND, DIRT, GRAVEL, CLAY, SOIL PARTICLES)
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 soil particles from a
disturbed land area or eroding stream bank to surface waters. Sediment can quickly fill in a
waterbody, clog the storm drainage system, and cause turbidity and problems for aquatic life.

Pollutant Source:
Likely Residential Sources: Yards, Driveways, Poorly Vegetated or Eroding Sites
Likely Commercial/Industrial Sources: Construction Sites, Landscapers, Clear-cut Land,
Farming, 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!
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. 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 (eroding streambanks, construction, exposed soil)
Key Outreach Messages:
 Any land-disturbing activity including gardening, planting, 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.
 There is a direct link between sedimentation and poor water quality and impacts on aquatic ecosystems and
habitat.
 Residents can plant groundcover, shrubs, and trees to hold soil in place and prevent erosion. Use native plants
whenever possible – they don’t need fertilizers and pesticides. For properties with sandy soil, mix organic matter
(i.e. compost) in with the sand to allow plants to grow better.
 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.
 Lack of vegetation along waterfront property and streambanks can produce significant erosion. Waterfront
property owners should be encouraged to plant vegetative buffers to stabilize eroding streambanks.
 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 (PESTICIDES, PRESSURE WASHING AND CLEANING SOAPS)
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
pollutant sources can contain toxic chemicals that can persist in the environment, causing toxicity
in humans and aquatic organisms, in addition to contaminating drinking water resources.

Pollutant Source:
Likely Residential Sources: Homeowners, Gardeners, Car/Boat Owners, etc.
Likely Commercial/Industrial Sources: Pressure Washers, Vehicle Washing Businesses,
Turf/Landscape Professionals, Restaurants, Other Businesses, 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 into the storm drainage system.
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 (pesticides, pressure washing/vehicle washing soaps and cleaners, etc.)

98

TARGET POLLUTANT: LITTER (PLASTIC, PAPER, CIGARETTE BUTTS, ETC.)
Litter is generated as a result of improperly or carelessly discarded plastics, food wrappers,
cigarette butts, etc. that can wash into waterways via the storm drainage system and impact
habitat, wildlife, and water quality. Plastic pollution is ubiquitous and is especially problematic
for the drainage system and for wildlife and aquatic habitat. Litter often takes a long time to break
down, if at all.

Pollutant Source:
Likely Residential Sources: General public, Motorists, Smokers, Students, etc.
Likely Commercial/Industrial Sources: Restaurants, Retail Centers, Construction Sites, 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!
Litter is carried by stormwater runoff into the drainage system where it can clog storm drains
and drainage routes and cause flooding on streets and property.
Litter that washes into local surface waters can be mistaken by fish, birds and other wildlife for
food that become sick or die from ingesting it. Wildlife also can 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, 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
clean tend to repel litter.

- Count of reported violations to Stormwater Hotline, Keep America Beautiful of NHC, or Swat -a-
Litterbug from New Hanover county

101

TARGET POLLUTANT: VEHICLE POLLUTION (VEHICLE FLUIDS, WASHING SOAPS/DETERGENTS)
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 via washing of vehicles, boats, and other
equipment. These fluids are insoluble and can easily contaminate water resources, as well as
poison fish and other aquatic organisms.

Pollutant Source:
Likely Residential Sources: Motorists, Backyard Mechanics
Likely Commercial/Industrial Sources: Vehicle Maintenance Repair Shops, Mobile Detailers,
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.
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.
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.
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 and detergents and
their impact on water quality.

102

Target Pollutant: VEHICLE POLLUTION (vehicle fluids, washing soaps/detergents)
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.
 Washing vehicles or boats using soaps/detergents can negatively affect water quality by contaminating them 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. If you must wash on pavement, use plain, clear water and no chemicals.
 On-site storage (i.e. fluids, batteries) has the potential to leak during filling, emptying, storage unit failure, or
vandalism.
 Business owners should be aware of and abide by the City’s Illicit Discharge Ordinance which states that
- 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
disconnected and permanently closed.
- Residents and businesses will be expected to prevent harmful substances from running off into the storm
drainage system.
- Fines for non-compliance with the City’s illicit discharge ordinance are up to $10,000 per offense.

Public Involvement/Volunteer Efforts Total Allocated Cost: $7953
Encourage public participation by engaging city residents/businesses/civic groups in a
volunteer Storm Drain Marking program in the city to involve and educate the community
about stormwater pollution. A minimum of 1 volunteer day with at least 5 community
volunteers and 14 drains marked is required. Agencies are welcome to do additional storm
drain marking beyond this requirement. Educational doorhangers will be distributed to
surrounding residences/businesses during storm drain marking. Assist in identifying areas to mark

113

drains, educate volunteers about stormwater pollution and the purpose of the storm drain marking
program, train volunteers in marking and safety, use supplied markers, and help provide oversight
of the program. A trained CFRW staff member and/or trained intern is required to be present
during all storm drain marking activities and with each volunteer group. ($770)

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
and recyclable materials removed, photographs to document work including before and after

114

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)

Policy for Reporting and Documentation of Sanitary Sewer Overflows and System Leaks
Cape Fear Public Utility Authority and City of Wilmington
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

131

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 a minimum
of four locations along one or more trunk lines during any given month 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

133

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

134

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-ye ar 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.

135

(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.

NEW HANOVER SOIL & WATER CONSERVATION DISTRICT
230 Market Place Drive, Suite 100
Wilmington, NC 28403

HOWBMP Quarterly Progress Report #4: April 1- June 30, 2019

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 a project manager for the Heal Our
Waterways- Best Management Practice Installations Program (HOWBMP). The HOWBMP Program
supports the council-adopted Bradley & Hewletts Creek Watershed Restoration Plan, with the goal of
reducing polluted stormwater runoff entering the creeks in order to improve water quality.

NHSWCD will provide project management and oversight for the installation of BMPs within the
designated watersheds in conjunction with the Heal Our Waterways program. ‘Project management’
includes activities such as the execution of a BMP project from start to finish including program
promotion, identifying sites and projects, collaboration, current owner title search, obtaining HOA
covenants/restrictions/permits, budgeting, technical assistance, design/engineering, permitting,
contracting, construction, homeowner/business/media relations, selection and reimbursement of
contractors, monitoring, and reporting.

BMPs will be identified for the purpose of reducing runoff volume and pollution into Hewletts Creek,
Bradley Creek, and the associated areas that drain directly into the Intracoastal Waterway. A potential
BMP project’s location, type, estimated volume reduction, and proposed budget will require written
notification to, and approval from, City Stormwater Services prior to any design, construction or other
contracted work. Acceptable BMPs are listed on the GIS Atlas form.

A recommended minimum of 4-6 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 can be prioritized based on
cost per cubic foot of volume reduction, as necessary.

During site evaluations, NHSWCD will educate property owners about the HOW Program (i.e.
information about the specific BMP, maintenance, annual spot checks, HOW Brochure distribution,
etc.) Once BMPs are installed, NHSWCD will provide the property owner with more specific BMP
FY 1819

158

maintenance hardcopy information, Creek Friendly yard sign, 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 database for
all installations and submit it at the end of each annual contract period.

The BMP installations will be funded by the City with a lump-sum allocation of $20,000 to NHSWD at
the beginning of the contract period. Any unused funds from this allocation will be reimbursed to the
City at the end of the contract period. NHSWCD will also reimburse the City for any returned funds
from non-compliant property owners. NHSWCD will issue any necessary tax forms to contractors or
property owners..

Reporting

Quarterly progress reports and invoices will be submitted in accordance with the following
provisions:

Submit cumulative quarterly progress reports and invoices according to the following quarters: July 1 -
Sept 30 (1st Quarter); October 1 - Dec. 31 (2nd Quarter); January 1 -March 31 (3rd Quarter); April 1 -
June 30 (4th Quarter). The 4th quarter progress report will serve as a compiled year-end summary report
and will be included in the City’s NPDES annual report.

Quarterly reports and invoices are due within 12 days of the quarter end date and will follow
templates and instructions set forth by Stormwater Services.

If the reporting due date falls on a weekend or a city-observed holiday, reports are due the
following weekday by 5pm. Any reports received late, including Quarterly Progress Reports,
Quarterly Invoices, other contract reporting, year-end compilation of records/reports, etc. will
result in an automatic overall reduction of the quarterly invoice payment amount according to
the following schedule:
 1-10 calendar days late - 10% reduction of the quarterly payment amount
 11+ calendar days late - 20% reduction of the quarterly payment amount

The quarterly invoice should use the supplied template which shows the % of each service completed
each quarter, invoice amount, and amount remaining to be paid. Invoices will be paid once the
quarterly progress report and invoice(s) are received and reviewed by the City for adequate progress.
Non-performance or inadequate progress may result in non-payment or reduction of payment. No pre-
payment of services will occur.

Reports and invoices that do not follow templates/instructions will be returned for correction; payment
will be processed once updated reports and invoices are received, reviewed, and approved.

NHSWCD will maintain all records and reports related to this contract on a fiscal year (FY) basis (July
1-June 30). These records should be retained for a period of at least 5 years. These files are public
record and should be accessible at the contracted agency location. In addition, an annual compilation
of all contract documents, records, reports, invoices, and pertinent educational materials or related
materials will be provided to the City of Wilmington Stormwater Services on a USB Flash Drive, CD,
or DVD (June 1 – July 31) for the entire contract year within 12 calendar days of the 4th quarter end
date.

159

For each BMP project, NHSWCD will provide the City with the necessary BMP project packet to
include:
BMP Info-
 Heal Our Waterways GIS Atlas Form
 Calculations sheet from Engineer - sizing and volume calculations
 Specific BMP design (ie. Rain garden, bioretention area, cistern, etc.)
Site Specific Info-
 Site plan (include aerials if available)
 Before & After photos of site (pre-BMP & post-BMP)
 Proof of property ownership through title search

APPENDIX K: DEFINITIONS

Act
See Clean Water Act.

Best Management Practice (BMP)
Measures or practices used to reduce the amount of pollution entering surface waters.
BMPs can be structural or non-structural and may take the form of a process, activity,
physical structure or planning (see non-structural BMP).

Built-upon Area
That portion of a development project that is covered by impervious or partially
impervious surface including, but not limited to, buildings; pavement and gravel areas
such as roads, parking lots, and paths; and recreation facilities such as tennis courts.
"Built-upon area" does not include a wooden slatted deck, the water area of a swimming
pool, or pervious or partially pervious paving material to the extent that the paving
material absorbs water or allows water to infiltrate through the paving material.

Clean Water Act
The Federal Water Pollution Control Act, also known as the Clean Water Act
(CWA), as amended, 33 USC 1251, et. seq.

Common Plan of Development
A construction or land disturbing activity is part of a larger common plan of development
if it is completed in one or more of the following ways:
• In separate stages
• In separate phases
• In combination with other construction activities
It is identified by the documentation (including but not limited to a sign, public notice or
hearing, sales pitch, advertisement, loan application, drawing, plats, blueprints, marketing
plans, contracts, permit application, zoning request, or computer design) or physical
demarcation (including but not limited to boundary signs, lot stakes, or surveyor markings)
indicating that construction activities may occur on a specific plot. It can include one
operator or many operators.

Department
Department means the North Carolina Department of Environment and Natural Resources

Division (DWQ)
The Division of Water Quality, Department of Environment and Natural Resources.

Director
The Director of the Division of Water Quality, the permit issuing authority.

Dry Weather Flow
Any flow in the MS4 that occurs after a 72 hour period without rain.

170

EMC
The North Carolina Environmental Management Commission.

Illicit Discharge
Any discharge to a MS4 that is not composed entirely of stormwater except .discharges
pursuant to an NPDES permit (other than the NPDES MS4 permit), allowable non-
stormwater discharges, and discharges resulting from fire-fighting activities.

Industrial Activity
For the purposes of this permit, industrial activities shall mean all industrial activities as
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

in the incorporated places, townships or towns within such counties; or
(c) Owned or operated by a municipality other than those described in
paragraph (a) or (b) and that are designated by the Director as part of the
large or medium separate storm sewer system.

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

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 BMP
Non-structural BMPs 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 Storm water
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.

172

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
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)(l4). The term does not
include discharges from facilities or activities excluded from the NPDES program

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.

173

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
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.
