INTRODUCTION
Stormwater Management Plan Overview
The North Carolina Division of Water Quality issued NPDES Phase II Permit NCS000406 to the
City of Wilmington effective November 12, 2012. 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, 2017 to June 30, 2018.
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 5 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 within areas where data is absent.
Continuation of Public Outreach and Public Participation efforts.
Continued effort to implement new SCMs at City facilities to improve water quality.
Implementation of several key actions of the Bradley and Hewletts Creek Watershed
Restoration Plan, including the installation of a large bioretention area through the
collaborative efforts of plan partners and stakeholders.
Wilmington continues to move forward with implementing the necessary goals and objectives
as outlined in their permit. Progress was made this year related to dry weather flow monitoring

and planning and also with improved in-house maintenance procedures. 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 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. Stormwater Services also provides semi-
annual inspections for privately permitted stormwater retention facilities. These inspections are
performed in order to ensure compliance with city maintenance standards. Compliance with
NPDES Phase II stormwater regulations also fall into this category.
Capital Improvements
The stormwater utility provides dedicated funding and staff resources for planning, designing,
and constructing capital projects. These 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 possible, capital projects incorporate innovative design or
best management practices (BMPs) to improve water quality and reduce the quantity of
stormwater runoff.
Operations and Maintenance
The City of Wilmington’s Maintenance Division is responsible for maintaining the public
drainage system. Maintenance activities consist of open drainage, closed drainage, street
sweeping, and best management practices (BMPs). The open drainage system consists of
roadside swales, ditches, channels, creeks, and ponds. The closed drainage system consists of
pipes, culverts, catch basins, and manholes. Both of these systems are maintained using manual
and mechanical techniques to insure that they remain open for proper drainage. Street
sweeping provides preventative maintenance to minimize the amount of trash, debris,
PERMIT NO. NCS000406
4
sediment, and other pollutants entering open or closed drainage routes. BMP maintenance
consists of activities necessary to keep over 75 BMP sites including ponds, wetlands, and bio-
retention areas in fully-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
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 grant funding. In
addition, Stormwater Services implements an extensive outreach, education, and public
involvement program that serves the citizens of Wilmington and includes a wide array of water
quality education programming and materials. These programs include school presentations,
homeowner association outreach, stormwater publications and giveaways, mass media
advertising, special event exhibits, workshops, volunteer cleanups and storm drain marking,
and collaborative efforts such as grant projects. 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
new ordinance.
Compliance through Public Education
The stormwater code enforcement program strives to maximize voluntary compliance through
public education and 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 2017-18, 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.
PERMIT NO. NCS000406
8
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 and the city’s
expectations as well as the ordinance and penalty amounts for any violations. Pet waste message
flags are used and distributed with ordinance information in parks and public places, and in
specific neighborhoods in response to complaints. The pet waste flyer is also available in poster
size for display when needed in parks and common areas.
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 targeting the general public as well
as specific source types that are typical in any urban area. These posters are kept on hand and
distributed to businesses on an as needed basis to inform and educate them and their employees in
restaurants, vehicle maintenance facilities, construction sites, on industry specific issues and best
management practices specific to their businesses on how to avoid and prevent stormwater
pollution. For issues that require investigation, assessment, and enforcement the process detailed
in the Illicit Discharge Detection and Elimination Manual is followed.
Cape Fear Public Utility Authority
The Cape Fear Public Utility Authority (CFPUA) currently employs three Environmental
Compliance Officers, one Environmental Compliance Supervisor, and one Environmental
Compliance Manager that implement and enforce elements of the City’s NPDES Wastewater
Discharge Permit to include the City’s Collection System Permit. As part of those requirements
the group regulates sanitary sewer overflows (SSOs) and eliminates any wastewater or other
polluted waters from leaving their system. They respond to reports and investigate leads generated
by the public or monitoring results as part of their permit requirement and respond using public
education, enforcement, and maintenance. The CFPUA copies the City on all SSOs and follows up
with monitoring results and clean up measures. The CFPUA has maintained right of entry on the
properties that it services. The city and CFPUA are working together to keep open lines of
communication, continue to build relationships, and combine resources in a continued effort to
locate chronic leaks and minimize release to MS4.
The CFPUA and the City continue to utilize the joint policy established in 2011 for the reporting
and documentation of SSOs and leaks. This policy provides procedures for CFPUA to follow
regarding reporting and documentation of SSOs that impact the City’s MS4. These guidelines will
enable the City to comply with Phase II reporting requirements as well as provide assistance to
CFPUA in mitigating any potential threat to public health and environment. This policy is attached
in Appendix D.

Water Quality
Monitoring Program Overview
In October 1997, the City of Wilmington contracted with the UNCW Center for Marine Science
for a project with the goal of assessing water quality in Wilmington City watersheds under base
flow conditions. Also, certain sites were analyzed for sediment heavy metals concentrations (EPA
Priority Pollutants). New Hanover County also participated in this effort for tidal creeks outside of
City jurisdiction. UNCW produced a combined report of results entitled Environmental Quality of
Wilmington and New Hanover County Watersheds. Immediately below is an overview of their
work methods. Following this overview is the executive summary of their most recent report.
The water quality data in these reports are presented from a watershed perspective. Some of the
watersheds cross political boundaries (i.e. parts of the same watershed may lie in the County but
not the City). Howe and Whiskey Creeks are examples. Water quality parameters analyzed in the
tidal creeks include water temperature, pH, dissolved oxygen, salinity/conductivity, turbidity,
nitrate, ammonium, orthophosphate, chlorophyll a, and in selected creeks fecal coliform bacteria.
Similar analyses were carried out in the City watersheds with the addition of total nitrogen (TKN),
total nitrogen (TN), total phosphorus (TP), total suspended solids (TSS) and biochemical oxygen
demand (BOD) at selected sites.
Water Quality Methods
Field parameters were measured at each site using a YSI 6920 Multiparameter Water Quality
Probe (sonde) linked to a YSI 650 MDS display unit. Individual probes within the instruments
measured water temperature, pH, dissolved oxygen, turbidity, salinity, and conductivity. YSI
Model 85 and 55 dissolved oxygen meters were also used on occasion. The instruments were
calibrated prior to each sampling trip to ensure accurate measurements. The UNCW Aquatic
Ecology laboratory is State-Certified for field measurements (temperature, conductivity, dissolved
oxygen and pH) and for laboratory chlorophyll a measurements.
The analytical method used to measure chlorophyll a is described in Welschmeyer (1994) and US
EPA (1997). Chlorophyll a concentrations were determined from the 1.0 micrometer glass fiber
filters used for filtering samples for nitrate+nitrite and orthophosphate analyses. All filters were
wrapped individually in aluminum foil, placed in an airtight container and stored in a freezer.
During the analytical process, the glass filters were separately immersed in 10 ml of a 90% acetone
solution. The acetone was allowed to extract the chloroph yll 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
PERMIT NO. NCS000406
13
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 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 20 of the Wilmington Watersheds Project. Water quality
data are presented from a watershed perspective, regardless of political boundaries. The 2017 program
involved 7 watersheds and 22 sampling stations. In this summary we first present brief water quality
overviews for each watershed from data collected between January and December 2017; note that fewer
samples were collected in 2017 because funding did not arrive until late fall.
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 population of approximately
12,200. Water column sampling was not funded during 2017, but new funding from the City allowed
UNCW to re-initiate sampling of Barnards Creek in January 2018.
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 2017 there were no significant algal blooms recorded, but there were several incidents of low
dissolved oxygen 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 2017.
High fecal coliform counts occurred at only one of the three sites in 2017, much better than previous
years. Two major and one minor algal blooms were recorded in 2017. Dissolved oxygen concentrations
were good in two stations and fair in the remaining mid-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 2017. Comparing inflows to outflows, there was a good bit of
variability in parameter concentrations and hence no significant differences between inflow and outflow.
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 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), three suffered from
low dissolved oxygen problems, although main lake oxygen problems were only minor.
Algal blooms are periodically problematic in Greenfield Lake, and have occurred during all seasons, but
are primarily a problem in spring and summer. In 2017 a filamentous green algal bloom occurred in
early spring and a massive summer blue-green algal bloom of Anabaena occurred late spring - summer.
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 high BOD occurred congruent with the blooms
in 2017. Stormwater runoff into the streams also contributes BOD materials into the lake. In 2017 all
PERMIT NO. NCS000406

tributary stations and all of the in-lake stations exceeded the fecal coliform State standard on 40% or
more of occasions sampled.
Greenfield Lake is currently on the NC 303(d) list for impaired waters due to excessive algal blooms.
Thus, in 2016-17 UNCW graduate student Nick Iraola, as part of his MS Thesis, conducted 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.
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 2017 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 2017. Turbidity was low, and only
one minor algal bloom was documented in 2017. Fecal coliform bacteria counts exceeded State standard
100% of the time at NB-GLR (the north branch), 80% of the time at MB-PGR (the middle branch), 60%
of the time at PVGC-9, and 80% of the time at SB-PGR (the south branch). The geometric means at
PVGC-9, MB-PGR, SB-PGR and NB-GLR all well 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.
During 2015-16 a wetland was created along Sharon and Patricia Drives, upstream of the sampling
location NB-GLR along the north branch of Hewletts Creek. Vegetation was sparse until summer 2017.
In future reports statistical comparisons will be made between pre-and-post wetland parameter
concentrations to measure wetland efficacy as a pollutant removal feature.
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 2017. The uppermost site HW-DT had one major algal bloom in the 2017
sampling. Both the uppermost station HW-DT and the mid-creek station HW-GP were rated poor for
high fecal coliform bacteria counts, exceeding the state standard on 50-100% of the times sampled.
However, dissolved oxygen concentrations were good at both sites in 2017.
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%. This creek was not sampled for water
quality by UNCW in 2017, but new funding from the City allowed UNCW to resume sampling of Motts
Creek in January 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
not violated in our 2017 samples. The North Carolina turbidity standard for estuarine waters (25 NTU)
was not exceeded. There were no major algal blooms present in our 2017 sampling. However, fecal
coliform bacterial concentrations exceeded 200 CFU/100 mL on 75% of samples in 2017, for a Poor
rating.
PERMIT NO. NCS000406

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 2017. 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 five occasions sampled, and fecal coliform
bacteria counts exceeded 200 CFU/100 mL on 20% 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 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 2017 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 (22 sites sampled for fecal coliforms) showed 18% to be in good condition, 18% in fair condition
and 68% in poor condition, an improvement over the previous year. Dissolved oxygen conditions
(measured at the surface) system-wide (22 sites) showed 64% of the sites were in good condition, 18%
were in fair condition, and 18% were in poor condition, an improvement from 2016. For algal bloom
presence, measured as chlorophyll a, 68% of the 22 stations sampled were rated as good, 23% as fair and
9% as poor. For turbidity, all of the 22 sites sampled were rated as good. It is important to note that the
water bodies with the worst water quality in the system also have the most developed watersheds with
the highest impervious surface coverage; Burnt Mill Creek – 39% impervious coverage; Greenfield Lake
– 37% impervious coverage; Bradley Creek – 28% impervious coverage.

ILLICIT DISCHARGE DETECTION AND ELIMINATION (IDDE)
1. Objectives for Illicit Discharge Detection and Elimination
a. Implement and enforce a program to address the detection and elimination
of illicit discharges into the MS4.
b. Maintain a storm sewer system map, showing the location of all major
outfalls and the names and location of all waters of the United States that
receive discharges from those outfalls;
c. Prohibit, through ordinance, or other regulatory mechanism, non-storm water
discharges except as allowed in this permit and implement appropriate
enforcement procedures and actions;
d. Implement a plan to detect and address non-storm water discharges, including
illegal dumping, to the MS4;
e. Inform public, employees, businesses, and the general public of hazards
associated with illegal discharges, how to recognize illicit discharges and
improper disposal of waste; and
f. Address non-storm water discharges or flows as identified in Part I, Paragraph
(8).
2. BMPs for Illicit Discharge Detection and Elimination
The permittee shall implement the following BMPs to meet the objectives of the Illicit
Discharge Detection and Elimination Program and shall notify the Division prior to
modification of any goals.
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.

Stormwater staff and City Planning review staff met this year to discuss Senate Bill 24 (SB24)
which could possibly allow food establishments to utilize outdoor grills for their patrons. The
result of this bill could lead to outdoor washing down of grills or runoff during rain events that
could lead to illicit discharges into the city’s MS4. The result of this discussion allowed for
planning, preventable measures and coordination between departments to evaluate site plans as
they go through the review process in order to limit the potential impact to the City’s drainage
system.
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

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 93% of the City
has been mapped as part of its stormwater inventory. This percentage demonstrates an increase
from 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.

c. Detect dry weather flows The permittee shall develop and implement 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.
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 City managed to investigate 5 trunk line investigations from major outfall locations across its
jurisdictional area, which was a decrease from the previous year partly due to weather and staff
scheduling. The locations were found within the Burnt Mill Creek, Greenfield Lake and Upper
Cape Fear River watersheds. Maps of the 5 locations and associated table are found in Appendix
D.
d. Investigations into the source of
all identified illicit discharges.

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.
The City continues to look at upgrading all data management systems throughout the organization.
There is a schedule to begin rolling out the new systems in spring of 2019 for certain departments
.
e. Track investigations and
document 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 has continued to utilize its improved 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 conducted training for its Engineering Staff during this reporting year (See Appendix D).
Refresher training and education for existing staff will be updated as necessary and implemented
every 2 years.
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 for 11+ years. As a result, the program reaches all 8th
grade science classes in New Hanover County Schools, this year serving 76 classes and 2,200+
students
This year’s annual Stormwater Watch newsletter was mailed to 40,000+ city residents with focus
on stormwater billing, litter reduction, and the UNCW water quality report of our local tidal creeks
and water bodies within the City limits.
Targeted media campaigns included digital billboards throughout the city, radio and television
standard and digital formats, and events such as the annual Earth Day Festival and Canines for
Clean Water.
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 was 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 fleet vehicles, and
promotional outreach items including cups, pens, reusable bags, magnets, and other giveaways to
the public.
To summarize hotline activity this past year: 20 calls were placed to the City’s Stormwater
PERMIT NO. NCS000406

hotline, 6 online hotline webform reports were submitted, and 357 emails and 85 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 Appendix I.
i. Enforcement The permittee shall implement a system to track the
issuance of notices of violation and enforcement actions
as administered by the permittee. The data maintained in
this system shall enable permittee 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 2017-2018 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 implement and enforce its IDDE program to address the detection and
elimination of illicit discharges. The City continues implementing its dry weather flow
monitoring program with field training for additional staff this year. Dry weather flow locations
will continually be updated and added through outfall investigations that are scheduled throughout
the year and also through investigations initiated by City field crews and citizen complaints.
The City has documented another year of Intelligov data, our data management system. The City
is currently reevaluating its data management system throughout the whole organization for
replacements and upgrades. These replacement programs could lead to increased efficiency and
documentation to help further meet NPDES Phase II requirements. The replacement may be
available to some departments in spring 2019.
The City continues to utilize the existing ordinances in place to address illicit discharges to its
system. To date, no changes to the ordinance have been necessary as it provides the adequate legal
authority to prohibit illicit connections and discharges and enforce the approved IDDE Program at
this time.
Public education and employee training regarding illicit discharges continues to be one of the
major goals for the City. Interestingly, of the 85 stormwater inquiries for possible illicit discharges
to the City’s Public Services Code Enforcement Officer, 44% were City employees, 21% were
from cooperating agencies and 35% were from concerned citizens. This is a good indication that
our employee training throughout the City for identifying illicit discharges is working along with
public education media and material that goes out to our citizens.
Dry weather flow methods and field procedures continue to be assessed through investigations and
data collection.
PERMIT NO. NCS000406

Objectives for Next Year
Continue to research and update locations for dry weather flow monitoring. Develop schedule
as new locations are identified.
Continue with the goal of completing 7 dry weather flow drainage segments per year as
identified in the City’s Public Services Strategic Plan.
Continue to evaluate the effectiveness of the Intelligov reporting practices. Assess locations of
offenders to determine repeat violations and make recommendations to address those sites.
Evaluate recently initiated NC statutes as needed to ensure that the City’s MS4 is not
impacted.
Continue with public education efforts to help reduce illicit discharges and illicit connections
to the City’s MS4.
Implement training sessions for other City field departments regarding IDDE.
Continue Inventory Mapping of areas identified. Reassess next mapping area.

September 15, 2009 to provide post construction controls in order to meet the requirements of the
City’s Phase II permit and to bring the ordinance into compliance with the new Coastal
Stormwater Legislation.
Currently the City is looking at changes to its Land Development Code. Planning for these
changes has been occurring during the last year with the City hiring a consultant to help make
recommendations for the changes. The main changes to the code that would affect stormwater
planning and review would involve redevelopment of properties. Tentatively, the draft of the new
Code should be available to review and discuss in early 2019.
b. Strategies which include BMPs
appropriate for the MS4
The permittee shall adopt the DWQ BMP Design
Manual or certify that the local BMP Design Manual
meets or exceeds the requirements in the DWQ BMP
Design Manual.
Accomplishments:
The DWQ BMP 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
BMPs 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.
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

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 BMPs 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.
e. City Code, Permitting
Regulations, Easement, and/or
Deed Restrictions and Protective
Covenants
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 easement 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 easement 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 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 new 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 operation and
maintenance of structural BMPs.
The permittee shall implement or require an operation
and maintenance plan for the long-term operation of the
structural BMPs required by the program.
PERMIT NO. NCS000406

implementation of the stormwater ordinance. The City will continue to make improvements in the
inspection process (as necessary) and its associated database for private BMPs.
Assessment of Program Implementation
The City has continued to maintain adequate legal authorities to meet the objectives of the Post-
Construction Site Runoff Controls program through its Land Development Code. In addition, 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.
The City’s Plan Review Engineers continue to their update their database in order to track projects
with stormwater control measures installed. This spreadsheet provides relevant information
regarding new development and redevelopment projects. This spreadsheet will continue to be used
for future permits issued and evaluated or modified if data extraction is warranted.
Objectives for Next Year
Review ordinances to determine if any changes are needed to improve the post-construction
requirements.
Review any drafts to changes in Land Code Development that may be available.
Continue to update and evaluate database of new or redeveloped projects to determine if
information can be improved, if documentation is adequate, and if modification for data
extraction is needed.
Continue with inspections of privately owned BMP to ensure compliance with City and State
maintenance requirements.

component and has the ultimate goal of preventing or reducing pollutant runoff
from municipal operations.
b. Provide employee training to prevent and reduce storm water pollution from
activities such as park and open space maintenance, fleet and building
maintenance, new construction and land disturbances, and storm water
system maintenance.
2. BMPs for the Pollution Prevention and Good Housekeeping for Municipal
Operations
The permittee shall implement the following BMPs to meet the objectives of the
Pollution Prevention and Good Housekeeping Program.
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.
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 surroun ding stormwater systems. Although no formal SPPP was
required for each individual site, t he City opted to be proactive in reducing the potential for
contaminants and other pollutants that could leave the sites. Site BMP recommendations were
implemented at some of the locations this reporting year such as the City’s Operations Complex
Coleman Sweeper Complex. Additional structural and non -structural BMP implementation will
continue at the other identified locations.
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 Pol ice
Headquarters location.
PERMIT NO. NCS000406
44
b. Operation and Maintenance
(O&M) for municipally
owned or operated facilities
The permittee shall maintain and implement, evaluate
annually and update as necessary an Operation and
Maintenance (O&M) program for municipally owned and
operated facilities with the potential for generating polluted
stormwater runoff. The O&M program shall specify the
frequency of inspections and routine maintenance
requirements.
Accomplishments:
Currently, The City relies on a SPCC plan and a S PPP 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 f or the Police Headquarters addresses inspections for their fueling
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.
This year the City has begun implementing an O&M plan for all of its locations where oil/water
separators are present. Th e Buildings Manager has begun to budget for getting these locations on
a regular quarterly schedule for inspection and maintenance in order to ensure their longevity
and functionality. The City plans to follow through with a contractor in the next budget y ear –
2019-20.
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 Co mplex
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 documentation 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 2018 -19 reporting year to bring all relevant personnel into a field
training session at all necessary locations.

d. Streets, roads, and public
parking lots maintenance
The permittee shall evaluate BMPs to reduce polluted
stormwater runoff from municipally-owned streets, roads,
and public parking lots within the corporate limits. Within
12 months, the permittee must update its Stormwater Plan to
include the BMPs selected.
Accomplishments:
The City currently utilizes BMPs that help reduce polluted stormwater runoff from streets, roads,
and public parking lots within its jurisdictional area. Stormwater crews sweep City streets with
curbing (on average) twice/month, NCDOT owned roads once/month, and City owned parking
lots from once/month to once/ quarter. City owned parking lots include City operations
facilities, City Hall, parks locations, and recreation facilities.
In reporting year 2017-18, street sweepers swept 10,543 curb miles while collecting 2,926 tons
debris, sediment, vegetation and trash potentially diverted from the stormwater sewer system.
In fiscal year 2017-18, hand maintenance and vacuum trucks cleaned 101,627 linear feet of pipe
and removed blockages and cleaned 13,525 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 implemented its improved procedures for decanting operations of vacuum trucks after
pipe or structural maintenance/cleaning occurs. The City began utilizing its own wet pond
facilities located throughout the City as potential decanting sites for maintenance crews while
conducting their jobs in these areas. The intent of this measure is to improve water quality to the
decanting methods that were previously being conducted in the field. This implementation was
met well with field crews and appears to be successful at this time. The City continues to further
look at all of its field maintenance activities to determine if improvements to water quality can
be incorporated.
e. Streets, roads, and public
parking lots maintenance

certifications are updated and renewed annually. Currently, there are 14 certifications for Parks
and Recreation staff and 2 certification for Stormwater/Public Services staff.
j. Staff training The permittee shall implement an employee training program
for employees involved in implementing pollution
prevention and good housekeeping practices.
Accomplishments:
The City documents staff training for site supervisors involved with the SPCC and SPPP. Sites
are reviewed at scheduled times during the reporting period to ensure that impleme nted SCMs
are working and being utilized and that staff is documenting their respective plans as necessary.
A supervisor training record for Fleet Maintenance is found in Appendix G.
Stormwater staff and the Public Services Safety Specialist review online employee training
annually through Otis Safety 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 addition, 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.
k. 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 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
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.
During the previous reporting year, Stormwater staff along with the Fleet Maintenance Manager,
began to evaluate the need for annual maintenance of the interior trench drains located along the
perimeter of the garage facility. Although no vehicle or equipment cleaning occurs at this location,
sediment and grit accumulates in the trench drains from the everyday maintenance of vehicles
pulled in and out of the building along with wind swept debris. Maintenance of the trench drains
will be now be conducted annually at the site to help eliminate any gross solids from entering the
surrounding stormwater system. This maintenance is to be determined for fall 2018.
PERMIT NO. NCS000406

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.
Assessment of Program Implementation
The City continues implementing its SPCC and SPPP for designated City owned facilities with the
potential to pollute receiving waters. Site SCMs continue to be implemented and documentation
has been addressed with building supervisors.
The City continues to evaluate implementing SCMs at other City facilities identified with the
potential to pollute based on the type of activities that occur there.
The City reviewed and compiled current herbicide, pesticide and fertilizer licenses to determine if
personnel are current in their training.
Stormwater Staff and the Public Services Safety Specialist have designated appropriate city
employees to complete required training for spill prevention and spill cleanup.
The City has evaluated all of its facility oil/water separators in order to begin a regular O&M

TOTAL MAXIMUM DAILY LOADS (TMDLs)
1. Objective
a. Determine whether a TMDL has been developed and approved or established
by EPA for the receiving water(s) of the MS4 stormwater discharge and/or
downstream waters into which the receiving water directly flows.
b. Develop and implement BMPs to reduce non-point source pollutant loading to
the maximum extent practicable (MEP) if the permittee is or becomes subject
to an approved TMDL with an approved Waste Load Allocation (WLAs)
assigned to stormwater.
c. If subject to an approved TMDL, the permittee is in compliance with the TMDL
if the permittee complies with the conditions of this permit, including developing
and implementing appropriate BMPs to reduce non-point source pollutant
loading to the maximum extent practicable (MEP). While improved water
quality is the expected outcome, the NPDES MS4 permit obligation is to reduce
non-point source pollutant loading to the maximum extent practicable (MEP).
The MS4 permittee is not responsible for attaining water quality standards
(WQS) at the ambient monitoring stations. The Division expects attaining WQS
will only be achieved through reduction from the MS4, along with reductions
from other nonpoint source contributors.
2. Best Management Practices (BMPs)
At any time during the effective dates of this permit, if the permittee is or becomes subject to an
approved TMDL with an approved Waste Load Allocation (WLAs) assigned to stormwater, the
permittee shall implement the following BMPs to reduce non-point source pollutant loading to
the maximum extent practicable (MEP):
BMP Measurable Goals
a. Identify, describe and map
watershed, outfalls, and
streams
Within 12 months the permittee shall prepare a plan that:
Identifies the watershed(s) subject to an approved TMDL
with an approved Waste Load Allocation (WLAs)
assigned to stormwater,
Includes a description of the watershed(s),
Includes a map of watershed(s) showing streams &
outfalls
Identifies the locations of currently known major outfalls
within its corporate limits with the potential of
contributing to the cause(s) of the impairment to the
impaired segments, to their tributaries, and to segments
PERMIT NO. NCS000406
50
BMP Measurable Goals
and tributaries within the watershed contributing to the
impaired segments and
Includes a schedule to discover and locate other major
outfalls within its corporate limits that may be
contributing to the cause of the impairment to the
impaired stream segments, to their tributaries, and to
segments and tributaries within the watershed
contributing to the impaired segments.
b. Existing measures
Within 24 months the permittee’s plan:
Shall describe existing measures being implemented
by the permittee to enhance water quality in the
watershed to which the TMDL applies; and
Provide an explanation as to how those measures are
designed to enhance water quality.
c. Assessment of available
monitoring data
Within 24 months the permittee’s plan shall include an
assessment of available monitoring data. Where long-term
data is available, this assessment should include an analysis
of the data to show trends.
d. Monitoring Plan
Within 36 months the permittee shall develop and submit to
the Division a Monitoring Plan for each pollutant of concern
or cause of impairment as specified in the TMDL. The
permittee shall maintain and implement the Monitoring Plan
as additional outfalls are identified and as accumulating data
may suggest. Following any review and comment by the
Division the permittee shall incorporate any necessary
changes to monitoring plan and initiate the plan within 6
months. Modifications to the monitoring plan shall be
approved by the Division. Upon request, the requirement to
develop a Monitoring Plan may be waived by the Division if
the existing and proposed measures are determined to be
adequate to enhance water quality and reduce non-point
source pollutant loading to the maximum extent practicable
(MEP).
e. Additional Measures Within 36 months the permittee’s plan:
Shall describe additional measures to be implemented
by the permittee to enhance water quality in the
watershed to which the TMDL applies; and
Provide an explanation as to how those measures are
designed to enhance water quality.
PERMIT NO. NCS000406
51
f. Implementation Plan Within 48 months the permittee’s plan shall:
Describe the measures to be implemented within the
remainder of the permit term to enhance water quality
in the watershed to which the TMDL applies and
Identify a schedule for completing the activities.
g. Incremental Success
The permittee’s plan must outline ways to track and report
successes designed to reduce non-point source pollutant
loading to MEP. Successes could include increased
inspections, expanded and/or tailored BMPs within the scope
of the six minimum measures, structural and non-structural
BMP installed and/or implemented, including retrofits, and
strategies developed and implemented for development and
redevelopment that include green infrastructure and LID
practices.
h. Reporting The permittee shall conduct an annual assessment of the
program to enhance water quality in the watershed to which
the TMDL applies and submit a report of the assessment to
the Division. Any monitoring data and information
generated from the previous year are to be submitted with
each annual report.
3. If no stormwater waste load allocation is specified in the TMDL
If there was no stormwater waste load allocation in the TMDL, in lieu of developing a
Water Quality Recovery Plan, the permittee shall evaluate strategies and tailor and/or
expand BMPs within the scope of the six minimum measures to enhance water quality
recovery strategies in the watershed(s) to which the TMDL applies. The permittee
shall describe the strategies and tailored and/or expanded BMPs in their Stormwater
Management Plan and annual reports.
4. Watershed Restoration Plan approved by the Division
Voluntary implementation of a Watershed Restoration Plan approved by the Division
constitutes compliance with this requirement and will allow deferment of TMDL
development if tracking and monitoring are provided that demonstrate progress in
implementing stormwater BMPs and/or enhancing water quality.
Bradley & Hewletts Creeks Watershed Restoration Plan Accomplishments:
The Bradley and Hewletts Creeks Watershed Restoration Plan has continued to make progress in
promoting volume-reducing best management practices (BMPs) to the public. Heal Our
Waterways (HOW), which is the informal name of the restoration plan, is becoming more widely
PERMIT NO. NCS000406
52
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 16,500+
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 2017 postcard educated recipients
about the new Heal Our Waterways
website, providing examples of information
found there and how it is beneficial. The
spring 2018 postcard addressed BMPs in
general, educating recipients about their
benefits and uses, as well as promoting a
rain barrel giveaway at the local Earth Day event.
Due to the success of last year’s advertising efforts,
efforts this year similarly focused on digital and radio
platforms. Following the success of 2016’s
downspout disconnection public service
announcement, starring local news anchor Jon Evans,
two more public service announcements were filmed
in 2018. Jon once again appeared as the spokesman
for the Heal Our Waterways program, this time
speaking about the use and benefits of rain barrels.
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 25,000 unique
visitors per month.
In addition to the rain barrel message
advertised on WECT, a digital billboard
campaign promoting a similar message
also aired. Contracting with Fairway
Outdoor, billboard locations were chosen
based on their proximity to Bradley and
Hewletts Creeks, appealing to the
viewer’s sense of place. The billboards
ran for two weeks in February, with 8
seconds of air time per minute, 24 hours a
day.
PERMIT NO. NCS000406
53
HOW also renewed its presence as an underwriting partner with local National Public Radio
affiliate, WHQR. This continued partnership with the local station will likely continue, as the
money spent there seems to correlate with website visitations and program participation. A 15-
second message aired 76 times over the course of 12 weeks. Each week, WHQR reached about
40,000 listeners in the Wilmington Designated Market Area. The WECT campaign also aired in
this timeframe as well.
City staff delivered a Heal Our Waterways
presentation to members of the Wilmington
West Rotary Club and a presentation on
rain garden design and installation for the
Surfrider Cape Fear Chapter and general
public. City staff also partnered with the
Manager of the North Carolina Coastal
Federation Southeast Regional Office to
conduct an information session with a
group of homeowners whose community
would be impacted by a grant-funded
stormwater retrofit.
HOW staff continued its presence this year
at Wilmington’s Earth Day Festival. As
with years past, the event was well-
attended, attracting 7,000+ 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 HOW program before. Additionally, 9 people
joined the mailing list at the Earth Day event in order to receive more information about how to
get involved.
HOW staff also attended the Lower Cape Fear Stewardship Development Awards Ceremony. An
educational display table was set up and staff engaged with attendees to discuss the Watershed
Restoration Plan, Stormwater Services, stormwater pollution and BMPs. Promotional materials
were distributed and contacts were made with local and regional environmental professionals.
Seventy five people were in attendance.
City Communications and HOW staff continue to maintain a
visually appealing website. The “Who’s Helping” page form
where citizens can report their individual efforts or express
interest in a stormwater reduction project through HOW has
proven useful this year. Eight entries were completed by
citizens expressing interest in helping decrease stormwater
pollution, three of whom were within the target watersheds.
This year, the Heal Our Waterways home page has received
1,620 unique views. This is up from 1, 044 the previous year. The Heal Our Waterways social
media presence has also increased, with Twitter and Facebook followers of 217 and 171,
respectively.
PERMIT NO. NCS000406

Heal Our Waterways ended two grants this year, continued two more, and is pending another. The
EPA 319 grant with NC State University ended, as did the Lynnwood Environmental
Enhancement Grant. The EPA 319 grant with the North Carolina Coastal Federation and the
Green Infrastructure Center Tree grant both continued. And an additional EPA 319 grant in
partnership with the North Carolina Coastal Federation and the University of North Carolina at
Wilmington was recently approved.
The NCCF Hewletts & Bradley Creek 319 Grant
continued through FY 17-18. Grant team partners
met to discuss the project on multiple occasions.
Through the grant, permeable pavement was
installed at both the New Hanover County
Arboretum and Waterman’s Brewing. Grant
partners also conducted a neighborhood
presentation at another planned installation
location. The grant will continue into 2019, with
planned installations at Wrightsville Beach Animal Hospital, a neighborhood off Greenville Loop
Road (Skystasail Drive), and a rain barrel giveaway/outreach campaign at the Palmetto Point
neighborhood.
The NCSU 319 grant ended in March 2018. No additional installations were created through the
grant. A re-planting and wetland plants workshop conducted by NCSU at the Lancaster
bioretention area occurred in June 2018 due to unforeseen runoff volume impacts.
In partnership with City Planning, Stormwater, and
Parks Divisions, the Green Infrastructure Center (GIC)
Tree grant made strides in FY 1718. The citywide
study looked at tree canopy and opportunities to use
trees in the city. A public meeting in November 2017
gauged citizen priorities and perceptions about the
existing tree canopy in Wilmington. The GIC then
incorporated the public comments into their
recommendation for improvements to City of
Wilmington code and policy. The City arborist will present the final product to City Council in the
future.
The Lynnwood/Glen Meade EEG grant successfully wrapped up in early 17-18. Actions on this
project included the addition of more wetland suitable plantings to the bioretention area, carried
out by volunteers from the NC Coastal Federation and City staff. Follow-up maintenance was also
done on the site in July 2017 to ensure proper function and to prevent erosion.
One new grant was accepted this year through the EPA 319 program. In collaboration with the NC
Coastal Federation and UNCW, a linear rain garden system as well as pervious pavement ribbons
will be installed on the UNCW campus.
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 four installations this year, and identified interested potential participants for next year.
Of this year’s participants in the program, three were homeowners in the Hewletts Creek
PERMIT NO. NCS000406
55
Watershed and one was an HOA installation. The total volume reduction from the HOWBMP
program this year was 809 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
developed in the previous year but required
some reform in early FY 1718. Staff worked
on inconsistencies and errors that were
identified in several of the GIS Atlas entries’
unit conversions and calculations. 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.
Annual Assessment & Evaluation of Plan Implementation:
Last year’s progress with the HOW program continued this year, with many of the growing pains
and difficulties experienced in years past being smoothed out. However, several other hurdles to
program success were identified. The website and citizen contacts yielded positive partnerships
and interactions. Likewise, the HOW media presence created a greater overall awareness of the
program, which manifested in additional public contacts and plans for future partnership.
While the groundwork is being laid for successful implementation of the plan, UNCW’s water
quality data still indicates that fecal coliform levels in the tidal creeks are increasing. This
illustrates the need for broader implementation and buy-in, as well as novel approaches to increase
BMP installation throughout the watersheds. One key item to pursue, which has seen great success
in other communities, is a rain garden/BMP cost-share program.
Adding a cost-share program, while beneficial if successful, will require several issues to be
addressed first. The main issue is that of City-held liability in working on or contracting on private
property. Preliminary work is being investigated to address this issue, and Stormwater staff will
work with the City Attorney’s office to find a solution.
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.

Much like years past, the HOW program has continued its environmental education and outreach
efforts this year by sending out winter and spring postcard mailings to watershed residents in FY
1718, focusing on the Heal Our Waterways website and Best Management Practices, respectively.
Public service campaigns were created this year,
with several new ads, seeking to raise awareness
of rain barrels. These advertisements on
WECT’s website and apps and The Weather
Channel app, followed in the same format,
starring news anchor Jon Evans. The WHQR
radio underwriting campaign was very similar
to years past, and again proved to be fruitful.
These campaigns brought a marked increase in
website visitation as well as three citizen contacts indicating awareness of the program because of
WHQR.
Another existing program with continued success this year is the partnership with New Hanover
Soil and Water Conservation District (NHSWCD), called the HOWBMP Program. Although the
number of installations was less this year, volume reduction was greater, and the number of
potential participants continues to increase. News and participation in the program continues to

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.
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:

Actions 3-1 and 3-2, regarding funding for retrofits in both of the target watersheds, have seen
progress in seeking additional funding for volume reduction BMPs. Funds are pending approval
for the newest 319 grant, to be administered by the NC Coastal Federation, to install retrofits on
the UNCW campus in the Bradley Creek Watershed. These funds should produce multiple
installations in the coming year, resulting in volume reduction.
HOWBMP installed retrofits in the Hewletts Creek Watershed this year. For four rain garden
installations, the volume reduction was 809 cubic feet.

The existing Hewletts Creek 319 grant, in partnership and administered by the NC Coastal
Federation, also produced multiple installations this year. One installation was for pervious pavers
at the New Hanover County Arboretum, located in the Bradley Creek Watershed. Pervious pavers
were also installed at Waterman’s Brewing, located in the “Drains to Intracoastal” watershed north
of Bradley Creek.

The HOW program has seen gains in the promotion of stormwater volume reduction efforts in
FY1718, from social media to traditional media campaigns to collaboration with UNCW and
NHSWCD.
Action 4-1 calls for the use of the GIS Atlas to aid homeowners and others in identifying cost-
effective retrofit opportunities while quantifying the impact of decreased runoff volume. For the
first time since the inception of this program, a working GIS Atlas has been created and is now
usable to track and quantify the impacts of volume reduction. It is also a valuable tool in providing
a visual representation of areas that are in greater need of retrofits. This, combined with the water
quality monitoring that is being conducted by UNCW, will prove to be an invaluable tool in the
coming years.
Actions 4-2 and 4-3 discuss working with landowners to disconnect impervious surfaces and the
promotion of LID retrofits of existing private development, respectively. In accordance with these
actions, through the NC Coastal Federation EPA 319 grant, a neighborhood has been identified as
a prime candidate for a rain barrel giveaway program. This program is set to take place in the
summer of 2018.
Also supporting Action 4-3, City Engineering staff and the Watershed Coordinator have worked
together to establish a working protocol for reporting new development, as well as proposed re-
development within the target watersheds. This has resulted in the Watershed Coordinator’s
inclusion in the Technical Review Committee concept review process. In FY 1819, concept plans
presented that are within the target watersheds will be met with suggested LID retrofits.
In support of Action 4-4, the Green Infrastructure Center (GIC) grant to protect and restore urban
tree canopy for stormwater management report should yield some success for this effort in FY 18-
19. Action 4-9 calls for the development of a UNCW campus-wide stormwater master plan.
While this has been stagnant for many years, this year the university finally made progress,
although it is not known to what degree. Separate from the master planning process, a preliminary
meeting was held between the UNCW Sustainability Captain, a research faculty member, and the
HOW Watershed Coordinator to set forth potential projects and collaboration to follow.

The partnerships that were strengthened in FY16-17 were further bolstered this past year. HOW
maintained all of the partnerships from the past, including UNCW, NC Coastal Federation, NC
State Cooperative Extension, New Hanover County Soil and Water Conservation District,
Surfrider Foundation Cape Fear Chapter, WECT TV-6, WHQR Public Radio, the Cape Fear
Group of the Sierra Club, Cape Fear Public Utility Authority, the Wilmington Tree Commission,
and Fairway Outdoor Advertising. New partnerships include the Wilmington West Rotary Club,
the American Public Works Association, and the homeowners associations of the Palmetto Point
and Shandy Point neighborhoods.
In accordance with Action 5-1, HOW delivered an educational program to the Wilmington West
Rotary Club that was attended by 27 people. For Action 5-5, HOW also delivered an informative
rain garden presentation for the Cape Fear Chapter of the Surfrider Foundation and interested
citizens. The ongoing partnership with the NC Coastal Federation continues to fulfil Action 5-2,
securing 319 grant for retrofits within both target watersheds.
In accordance with Action 5-6, the partnership with UNCW has continued. UNCW has partnered
with the NC Coastal Federation and the City of Wilmington on the application of a 319 grant. This
grant specifies locations on UNCW’s campus to install runoff-reducing retrofits.

Water quality is still being closely monitored by UNCW, in accordance with Action 6-2. The most
recent report, published in April of 2018, yields some frustrating results. Fecal coliform bacteria
levels at five of the eight monitoring sites within the two target watersheds were higher in 2017
(the most recent data) than in 2016. This illustrates the need for a greater focus on runoff-reducing

installations in the coming years. With established programs like HOWBMP in place, additional
programs and approaches will be necessary in order to positively impact results. A BMP cost-
share installation program is one such addition, as is the promotion of BMP installations at the
concept review stage of Technical Review Committee meetings.
This does not mean that the plan has not been successful, however. While installations must
increase for runoff volume to be reduced, there are still many facets of the program that have been
positive. Website visits and social media contacts have both increased markedly. Public
interaction has increased both in quantity and in quality, meaning that interactions with members
of the public involve a noticeably higher level of awareness on the topic of water quality related to
stormwater runoff than in years past.
Five-Year Plan Assessment
Five years have passed since the inception of the Bradley and Hewletts Creeks Watershed
Restoration Plan. Over the course of those five years, many lessons were learned, and much was
accomplished. Likewise, areas for improvement were identified in order to support the plan
objectives into the future.
From the beginning of the plan, there were several areas that have taken considerably longer to
implement than was originally intended. Both the GIS Atlas and the Heal Our Waterways website
took until FY 1617 to be fully operational. Likewise, partnerships that were anticipated to be
productive, like New Hanover County Schools, have experienced unforeseen setbacks.
Fortunately, programs and partnerships that were not considered at the beginning of the plan, such
as HOWBMP and the partnership with the Surfrider Foundation, have proven fruitful.
Stormwater volume entering the target areas of Bradley and Hewletts Creeks has not decreased as
rapidly as originally intended. But over time, the processes needed to accomplish that goal have
become clearer. The success of the HOWBMP program has warranted a closer look at how the
City of Wilmington can increase the installation of BMPs on private property. This has catalyzed
the development of the BMP cost share program, set for implementation in FY 1819.
As with any plan, adjustments are necessary as time and unforeseen constraints arise. Over the last
five years, the groundwork for the implementation of the plan was lain. Now, in the five years to
come, we should build upon that groundwork to see measurable gains in water quality and a
measurable decrease in stormwater volume entering the target areas. We can do that through
continued use of educational efforts and partnerships, while implementing new ideas and
approaches to volume reduction.

Introduction
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, auto
fluids, fertilizers, pesticides, litter, and yard waste and carries them through the stormwater
drainage system, directly into our 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:
9,000 catch basins and manholes
220 miles of pipe
200 miles of open drainage (ditches, creeks, and channels)
145 acres of retention ponds including Randall Pond and Silver Stream Pond
12 miles of culverts under roads
Greenfield Lake, Love Grove Tidegates
Stormwater BMPs such as Kerr Avenue Wetland, Park Avenue Bioretention Area, Wade
Wetland, etc.
This plan for Public Education and Outreach and Public Participation and Involvement is a
segment 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. The
permit authorizes the City of Wilmington to discharge stormwater from their municipal separate
storm sewer system (MS4) to the receiving waters of the State within the Cape Fear and White
Oak River Basins, under Environmental Protection Agency’s National Pollutant Discharge
Elimination System (NPDES) Program.
As required by the NPDES Permit, the City of Wilmington’s Stormwater Plan must detail the
City’s outreach program for the five-year term of the stormwater permit. This document serves as
the Outreach and Education Plan.
Since 1993, scientists at the UNC Wilmington Center for Marine Science Research have been
assessing the water quality of Wilmington’s major waterways. Approximately 70 sampling sites
assess the water quality of 10 of Wilmington’s tidal 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.
Public education, outreach, and participation are essential tools to develop stewardship and
awareness of stormwater pollution issues in Wilmington. By successfully reaching out to citizens

and businesses, we can reduce the pollution in our local surface waters preserving them as a
healthy, beautiful resource for our area.

Mission of Stormwater Services
The City of Wilmington Stormwater Services provides comprehensive management of the stormwater
drainage system in order to protect our community and environment.
Goals & Objectives ~ Outreach, Education, Involvement Program
The City of Wilmington Stormwater Services strives to improve local water quality by creating
awareness of stormwater runoff issues through public education and outreach and public
participation and involvement.
Through education, outreach, and involvement we educate citizens, businesses and employees
about the stormwater drainage system, sources of stormwater pollution, the direct impacts of
stormwater pollution on local waterways, and what we can do as a community to prevent and
reduce stormwater pollution. The program complies with the City’s NPDES stormwater permit.
The education program addresses the following facts as a basis for education efforts:
- Storm drains and drainage conveyances (i.e. ditches) carry water directly to local
waterways without any treatment. Only rain should go down the storm drain!
- Impervious surfaces increase the speed and volume of polluted stormwater runoff
entering the stormwater drainage system.
- Polluted stormwater runoff flows directly into local waterways where it impacts water
quality, aquatic habitat, shellfish harvest areas, and drinking water supplies.
- Plants, shrubs, trees, and other vegetation greatly reduce stormwater pollution by
absorbing and filtering stormwater runoff and preventing soil from washing away.
- Reduce the amount of polluted stormwater runoff entering local waterways by utilizing
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, and re-routing downspouts to grassy areas allow
stormwater runoff to soak into the ground and be cleaned and filtered naturally.
The program also addresses the six major pollutants that impact Wilmington’s waterways:
1) Fecal coliform bacteria
2) Nutrients
3) Sediment
4) Chemicals
5) Litter
6) Vehicle Pollution
PERMIT NO. NCS000406
79
Target Pollutants, Sources, and Audiences
The following pollutants have been identified as significant sources of pollution in Wilmington’s
waterways. Many of these pollutants also negatively impact the proper functioning of the stormwater
drainage system. These particular pollutants were chosen based on several sources including UNCW’s
water quality monitoring data, New Hanover Animal Control statistics, and the 2006 NC 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 water quality
data and trends.

Target Pollutant: FECAL COLIFORM BACTERIA (domestic and wild animal waste)
Nutrients, such as nitrogen and phosphorus, enter our waterways in excessive amounts via
stormwater runoff that carries fertilizers and yard waste into the storm drainage system. High
nutrient loads causes algal blooms, low dissolved oxygen levels, fish kills, and impaired aquatic
habitats.
Pollutant Source:
Likely Residential Sources: Domesticated Animals, Stray and Feral Animals
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 water quality monitoring. The primary source of this bacterial
pollution is canine and outdoor cat waste.
Stormwater runoff washes bacteria, parasites, viruses, and nutrients from animal waste directly
into our waterways.
There is a direct correlation between the amount of impervious surface coverage and fecal
coliform bacteria counts in Wilmington’s waterways.
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.
High levels of fecal coliform bacteria can cause diseases and infections in humans upon
contact such as roundworm, salmonellosis, toxoplasmosis, E. coli, and gastroenteritis.
PERMIT NO. NCS000406
81
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.
Dogs 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; ste ps should be taken to
control their waste as well.
Bacteria can cause diseases in humans and other animals.
Pet owners have a responsibility to clean up after pets and dispose of the waste properly.
Debunk barriers to cleaning up after pets (i.e. it’s not fertilizer, it’s okay to use a bag to pick it up with your
hand, pet waste is still a problem even if it’s in your own backyard, 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.
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.

PERMIT NO. NCS000406
83
Target Pollutant: NUTRIENTS (fertilizers, yard waste)
Nutrients, such as nitrogen and phosphorus, enter our waterways in excessive amounts via
stormwater runoff that carries fertilizers and yard waste into the storm drainage system. High
nutrient loads causes algal blooms, low dissolved oxygen levels, fish kills, and impaired aquatic
habitats.
Pollutant Source:
Likely Residential Sources: Homeowners, Gardeners, etc.
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
landscaping companies.
Improper 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 organic matter can also flow through the drainage system
introducing nutrients and pesticides into waterways.
Fertilizers and yard waste that end up in local surface waters impact aquatic life 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.
PERMIT NO. NCS000406
84
Target Pollutant: NUTRIENTS (fertilizers, yard waste)
Key Outreach Messages:
A direct link exists between improper fertilizer application and yard waste disposal and poor water quality
resulting in algal blooms, fish kills, and habitat degradation.
Grass cycle! 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 for City pickup.
Before fertilizing, get a 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, grass cycling, 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 f ertilizer from
driveways and streets after application.
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.
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.

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, etc.
Likely Commercial/Industrial Sources: Construction Sites, Landscapers, Clear-cut Land, 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. The waves created by boaters can also cause
accelerated erosion near the banks.
Excessive sedimentation can fill in a water body or clog the storm drainage system, leading to
flooding. Sedimentation also impacts bottom-dwelling organism by smothering fish eggs,
shellfish, coral and benthic (bottom-dwelling) plants.
Sediment can also cause water to become cloudy, also known as turbidity. Turbidity impairs
the photosynthesis of aquatic plants, as well as the ability of aquatic animals to breathe and see
prey/predators.
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.
PERMIT NO. NCS000406
87
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 sediment and poor water quality, in addition to impacts on aquatic life 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 gro w 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 drainage system.
Lack of vegetation along waterfront property and streambanks can produc e significant erosion. These types of
property owners should be encouraged to plant vegetative buffers.
Developers should follow all sedimentation and construction site laws and practices. Construction site violations
can be reported to the State Hotline: 1-800-STOP-MUD

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 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, 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 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 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 insects, humans and other wildlife, as well as entire aquatic ecosystems.
PERMIT NO. NCS000406
89
Target Pollutant: CHEMICALS (pesticides, pressure washing/vehicle washing soaps and cleaners, etc.)
Key Outreach Messages:
There is a direct link between the use of chemicals on land (i.e. pesticides, pressure washing cleaners) and water
quality and habitat impacts (i.e. frogs with six legs).
Install native plants which do not require pesticides or fertilizers.
Use alternatives to pesticides such as ladybugs, weeding by hand, and organic pesticides.
If you must apply pesticides, read the labels and apply the correct amounts. Do not apply before rain.
Suggest less toxic, environmentally-friendly alternatives to chemicals.
Promote info on how to properly dispose of chemicals and other household chemicals, including promotion of
Household Hazardous Waste Collection Days.
Pressure washing surfaces and washing cars/boats using soaps or cleaning agents of any toxicity level can
negatively affect water quality. These surfaces can only be washed legally with plain, clear water.
Wash on grassy areas that can absorb and filter the chemicals and wastewater naturally.
Businesses are required to capture and discharge the wastewater legally in a treatment system.
The City’s Illicit Discharge ordinance specifies that it is unlawful to dispose of or discharge any substance other
than stormwater into the storm drainage system. Fines are up to $10,000 per offense.
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: LITTER (plastic, paper, cigarette butts, etc.)
Litter is generated as a result of improperly discarded plastics, food wrappers, cigarette butts, etc.
that can wash into waterways via the storm drainage system and impact habitat, wildlife, and
water quality.
Pollutant Source:
Likely Residential Sources: Motorists, Smokers, General public, Trash pickup incidental litter,
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 is often produced as a result of being dropped during trash pickup.
Litter introduces chemical pollutants into waterways, such as plastics and cigarette butts.
Cigarette butts are a major source of litter and contain many dangerous toxins that can leach
into waterways.
Littered areas beget litter; areas that are clean tend to repel litter.
PERMIT NO. NCS000406
92
Target Pollutant: LITTER (plastic, paper, cigarette butts, etc.)
Key Outreach Messages:
Flooding of streets/property is sometimes attributed to the accumulation of litter in the drainage system.
A direct link exists between animal impacts, habitat destruction, and water quality as a result of littering.
Cigarette butts leach chemicals such as cadmium, lead, and arsenic into the aquatic environment within one hour
of contact with water.
The 2011 Ocean Conservancy International Coastal Cleanup identified cigarette butts as the #1 most littered
item.
Litter attracts wildlife to the side of the road where they are likely to get hit by oncoming vehicles.
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. BMPs can also trap litter so it doesn’t wash
away.
Target
Audience
Audience Description
(Why Selected?) Suggested Outreach Strategies
Youth (8th grade
presentations)
Litter habits cannot be
confined to a particular
demographic in most cases.
However, targeting 8th
graders during yearly
presentations should be a
priority since they are in the
developmental stage of
thinking and forming
opinions.
Make students aware of the impact of littering and the toxicity
of many littered items
Emphasize easy solutions to littering - using trash or
recycling receptacles
Promote the 5 R’s: Reduce, Reuse, Recycle, Refuse,
Repurpose
Explain the negative impacts on wildlife species (i.e. plastic
bags look like jellyfish to sea turtles)
Smokers Cigarette butts are the largest
environmental litter problem
both locally and worldwide.
Target both male and female
smokers.
Display signs encouraging proper disposal of cigarette butts
in public areas (i.e. Wave Transit buses)
Post outreach materials on stormwater website and GTV
Encourage use of ashtrays for smokers
Distribute pocket ashtrays at public events
Motorists and
Pedestrians
Along roadways, motorists
(52%) and pedestrians (23%)
are the largest contributors of
litter. Target males and
females.
Educate citizens about North Carolina’s Swat-A-Litterbug
program via website and GTV
Remind motorists about the proper disposal of trash by
displaying educational signs on public transportation vehicles
(i.e. Wave Transit buses)
Encourage use of car litterbags for proper trash disposal
Assessment & Evaluation
Conduct an informal poll before 8th grade presentations to gauge how many students litter and then pledge not to
litter after the presentation.
Elicit count of Stormwater Maintenance Department responses to clogged stormwater drainage system
components as a result of litter.
Have Stormwater Maintenance crews continually provide field observations of problem litter areas for clean -up
by community service workers or Cape Fear River Watch.
Periodically assess the litter disposal habits of Wilmington residents by:
- Direct observation of habits
- Surveys of habits
- Count of citations issued pertaining to improper litter disposal habits
- Count of reported violations to Stormwater Hotline, Keep America Beautiful of NHC , or Swat-a-
Litterbug from New Hanover county
PERMIT NO. NCS000406

Target Pollutant: VEHICLE POLLUTION (vehicle fluids, washing soaps/detergents, etc.)
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. 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 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 emptying into our waterways.
Commonly, it is the backyard mechanic that is illegally dumping or draining vehicle fluids.
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
toxic for 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.
PERMIT NO. NCS000406
94
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 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 vehic le
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, and/or use a commercial car wash which recycles
and treats wash water. 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, emptyi ng, 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.
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.

Conduct Enviroscape Presentations for at least 1/3 of 8th grade science classes in New
Hanover County Schools each semester for the entire school year. The Enviroscape watershed
education presentation is an integral component of the 8th grade science curriculum in New
Hanover County Schools. Presentations will be done in coordination with other cooperating
environmental agencies and will focus on the specific NC Essential Standard and Objectives for
the Hydrosphere/Hydrology unit. Enviroscape instructors will be trained, certified, and follow all
applicable Enviroscape presentation policies and procedures as set forth by the City of
Wilmington Stormwater Services. A maximum of 3 trained Enviroscape instructors from each
agency (which includes the Enviroscape supervisor) are permitted to deliver presentations in 8th
grade. Enviroscape supervisors are responsible for ensuring that their instructors are fully trained,
certified, and observed accordingly and kept up to date on the script, photo aids, maps, props and
other pertinent presentation information. Contracted Enviroscape supervisors will deliver a
minimum of two presentations each semester (2 in the fall semester, 2 in the spring semester).
Additional presentations given should not conflict or duplicate the 8th grade presentations in any
fashion; a summary should be provided in each quarterly report for any additional presentations
given. Other efforts may include assisting with curriculum development, scheduling presentations,
teacher relations, and training and observing instructors. ($2200)

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
drains, educate volunteers about stormwater and the purpose of the 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. ($700)

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 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. 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 in advance to make sure the area is actually 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.
PERMIT NO. NCS000406

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 CD of
documents/materials.
Efforts should be made to inform the local media/social media about upcoming cleanup events. In
addition, significant water quality problems identified during cleanups will be reported
immediately to the appropriate officials, including the city’s Stormwater Compliance Officer.
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 10 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/recyclable
materials removed, photographs to document work completed including before and after of
cleanup site, volunteer photos, and documentation of efforts to secure volunteers and promote the
event in the media/social media. ($5430)

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.
PERMIT NO. NCS000406
130
The selection of major trunk lines for inspection will be a strategically targeted effort to isolate
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
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
PERMIT NO. NCS000406
132
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
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.
PERMIT NO. NCS000406

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

RE: Storm Water Maintenance Inspection - «SUBD_NAME»
(Parcel # «PIN»)
The City of Wilmington Storm Water Services Section has recently completed a routine inspection
of the storm water management facilities at «SIT_ADDR» for the above referenced site. The
facility was inspected for compliance with the operation and maintenance requirements as outlined
in the City’s Technical Standards Manual. The City will be conducting these inspections a
minimum of twice a year. Our ----------- (date) inspection indicates that the storm water facilities

According to the storm water management specifications and standards and the inspection and

progress of any corrective action. I will be happy to work with you toward a satisfactory
resolution of this matter. If you have questions, please contact me at 341 -4694. Your cooperation
and assistance in the City’s storm water management efforts is greatly appreciated.

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 (BMP) 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
FY 1718
PERMIT NO. NCS000406
146
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 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:
Quarterly reports and invoices for contract fees are due within 10 days of the quarter end date
and will follow templates and instructions set forth by Stormwater Services.
Submit cumulative quarterly progress reports and invoices for work performed according to
the following quarters: July 1 - Sept 30; October 1 - Dec. 31; January 1 -March 31; April 1 -
June 30. The 4th quarter progress report will serve as a compiled year end summary report.
The quarterly invoices should use the supplied template which shows the % of each service
completed each quarter, invoice amount, and amount remaining to be paid. Copies of invoices
for BMP installations will be provided to the City with quarterly reports/invoices, and also
included with individual BMP project packet(s). Invoices will be paid once quarterly progress
report and invoice 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.
PERMIT NO. NCS000406

NHSWCD will maintain all records, reports, and invoices 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. In addition, an annual compilation CD or DVD copy will be provided to the City of
Wilmington Stormwater Services by July 10th for the prior FY. These files are public record
and should be accessible.
For each BMP project, NHSWCD will provide the City with the necessary BMP project
packet to include:

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
100,000 or more, except municipal separate storm sewers that are located

(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
roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches,
manmade channels, or storm drains):
(a) Owned or operated by the United States, a State, city, town, county,
district, association, or other public body (created by or pursuant to State
law) having jurisdiction over disposal of sewage, industrial wastes,
stormwater, or other wastes, including special districts under State law
such as a sewer district, flood control district or drainage district, or
similar entity, or an Indian tribe or an authorized Indian tribal
organization, or a designated and approved management agency under
Section 208 of the Clean Water Act (CWA) that discharges to waters of
the United States or waters of the State.
162
(b) Designed or used for collecting or conveying
storm water;
(c) Which is not a combined sewer; and
(d) Which is not part of a Publicly Owned Treatment Works (POTW) as defined
in 40 CFR 122.2
Non-stormwater Discharge Categories
The following are categories of non-stormwater discharges that the permittee shall
address if it identifies them as significant contributors of pollutants to the storm sewer
system: water line flushing, landscape irrigation, diverted stream flows, rising
groundwater, uncontaminated groundwater infiltration, [as defined in 40 CFR
35.2005(20)], uncontaminated pumped groundwater, discharges from potable water
sources, foundation drains, air conditioning condensation, irrigation water, springs,
water from crawl space pumps, footing drains, lawn watering, individual residential car
washing, flows from riparian habitats and wetlands, dechlorinated swimming pool
discharges, and street wash water (discharges or flows from fire fighting activities are
excluded from the definition of illicit discharge and only need to be addressed where
they are identified as significant sources of pollutants to waters of the United States).
Non-structural 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.
163
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.
164
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.
