PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the City of Henderson will comply with its National Pollutant Discharge Elimination System (NPDES)
Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the Clean Water
Act to meet the federal standard of reducing pollutants in stormwater runoff to the maximum extent
practicable.
This SWMP identifies the specific elements and minimum measures that the City of Henderson will
develop, implement, enforce, evaluate and report to the North Carolina Department of Environmental
Quality (NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with
^ the MS4 Permit number NCS000542, as issued by NCDEQ. This permit covers activities associated with
the discharge of stormwater from the MS4 as owned and operated by the City of Henderson and located
within the corporate limits of the City of Henderson.
In preparing this SWMP, the City of Henderson has evaluated its MS4 and the permit requirements to
develop a comprehensive 5-year SWMP that will meet the community's needs, address local water
quality issues and provide the minimum measures necessary to comply with the permit. The SWMP will
be evaluated and updated annually to ensure that the elements and minimum measures it contains
continue to adequately provide for permit compliance and the community's needs.
Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along
with any approved modifications of the SWMP, are incorporated by reference into the permit and become
enforceable parts of the permit.

IPART 3: MS4 INFORMATION
3.1 Permitted MS4 Area
This SWMP applies throughout the corporate limits of the City of Henderson, including all regulated
activities associated with the discharge of stormwater from the MS4. The map below shows the corporate
limits of City of Henderson as of the date of this document. Please note that the corporate city limits are
defined per ordinance but sometimes the city limit line splits parcel lines, these splits occur due to plat
subdivision or recombination. The ETJ is an arbitrary boundary defined as 1 mile from the city limits line
and this boundary has been plagued with split parcels but Henderson staff has worked hard to reduce the
amount of splits to provide consistent protections for those county residents, while trying to limit the
negative impacts of city regulations where a small split may create a burden.

3.2 Existing MS4 Mapping
The City of Henderson's Engineering Department is performing the current MS4 mapping which includes
the location of stormwater inlets, pipes, junction boxes, stormwater control measures (SCMs) and
Outfalls. Henderson's mapping to date has not included ditches from an asset inventory standpoint but,
they are delineated on our base maps by knowing how to interpret contour lines. As the city of
Henderson's MS4 program matures we will map the streams and ditches to include the condition
(physical and water quality) and morphology.
The City of Raleigh's stormwater department was very helpful with sharing their knowledge, experiences
and nomenclature with how to map the City of Henderson's stormwater system. While this collaboration
was fantastic in getting our mapping program up and going it was overwhelming due to the limited staff
we had and the extent of work Raleigh had put into their system. Therefore the City of Henderson had to
limit the scope of what Raleigh has done but with the intent of collecting the majority of the pertinent
data. The City of Henderson hired 2 part-time interns over the last two years to collect the data Our
interns were trained to use GPS equipment(Arrow Gold) and ESRI collector on an Apple iPad. Initially
= the data collected was labor intensive due to the amount of post processing and the re-training that was
required due to the GIS technician attrition. The current GIS Technician was able to develop a script to
batch process the points and significantly reduce the amount of post processing, eventually in late 2019
the GPS software improved and the point data was processed/corrected during collection. The GPS
equipment on the market today is attainable at a price point and the accuracy has significantly improved
.A so that most of our data has a 1-cm accuracy.
The City of Henderson's Engineering department has collected the stormwater data in GIS and then
pushed this data over to an asset inventory system (Cartegraph) so our Public Works (PW) Department
can perform work against these assets. The PW crews are currently working with the Engineering
Department to correct the stormwater maps. The GIS interns during the collection of the data were told
NOT to remove inlet covers or physically enter these structures due to safety issues and confined space
concerns. These restraints on the data collection hampered the intern's ability to determine pipe size,
invert depth, condition assessment and flow direction. While the stormwater system map is approximately
90% mapped there are inaccuracies in the data which are being improved in an on -going basis. One of
the more difficult legal issues to address with respect to mapping is distinguishing where private and
public system start and stop (i.e. a strip mall may build and attach to Henderson's public collection
system route the upstream flow through their private collection system then discharge back into a public
collection system. This brings up questions of construction standards, beneficial use, maintenance and
operations and future improvements.)
Please note that Henderson does not have a public facing map to any of our systems (water, sewer, roads
and stormwater). Henderson does not want developers making engineering decisions based on a map that
may contain errors. We require all developers to contact engineering about their plans then Henderson
reviews these plans and ground truths to verify if the system can accommodate the additional capacity.

*An outfall is a point where the MS4 discharges from a pipe or other conveyance (e.g. a ditch) directly
into surface waters. Major outfalls are required to be mapped to meet permit requirements. A major
outfall is a 36-inch diameter pipe or discharge from a drainage area > 50-acres; and for industrial zoned
areas a 12-inch diameter pipe or a drainage area > 2-acres.

** Receiving streams and their tributaries have been identified as well as the sub -basins. Henderson
needs to evaluate the drainage basin with respect to NCDEQ guidance to identify and classify the
outfalls. In many cases a stream may receive multiple discharges within a short reach and if this meets
the acreage requirement then Henderson has noted this as an Outfall.
3.3 Receiving Waters
The City of Henderson MS4 is located within the Tar-Pamilco and Roanoke River Basins and discharges
directly into the receiving waters as listed in Table 2A and 213 below. Applicable water quality standards
listed below are compiled from the following NCDEQ sources:

The City of Henderson recognizes that the Environmental Protection Agency in conjunction with the
North Carolina Department of Environmental Quality has done tremendous work with respect to hypoxia
problems in the lower water column of Pamlico Estuary as well as a thorough review of the factors
leading to this oxygen depletion. The promulgation of the Nutrient Sensitive Waters and the associated
Best Management Practices (BMPs) now known as Stormwater Control Measures (SCMs) have made
positive strides towards reducing the negative impacts of development on downstream water bodies. But
even with these positive steps forward there is so much more that can be done and NCDEQ has
recognized and identified 6 measures to improve stormwater quality which includes; education, citizen
participation, illicit discharge enforcement, construction runoff, post construction runoff and pollution
prevention and good house -keeping at municipal operations.
EPA/DEQ's report identified Total Nitrogen (TN) and Total Phosphorus (TP) as primary constituents of
interest to reduce the oxygen depletion. The NSW regulations have placed discharge limits from SCMs
on both these constituents as well as providing the efficiencies of removal for these constituents by the
SCMs. Currently the TN discharge limit is set at 4.0 lbs/acre/year and TP is set at 0.4 lbs/acre/year from
a new development site and a 30% reduction in TN from existing sites. Henderson's City Engineer
reviews all plans and calculations for compliance to the NSW regulations. New developments and their
associated SCMs work closely with the City and Morgensen Mitigation Bank so the developer can
purchase nutrient credits and come into compliance with the tools provided by NCDEQ.
Henderson's City Council has received the stormwater Notice of Violation in June 2020 and adopted a
Resolution to not only implement the measure outlined in NCDEQ's MS4 Stormwater Program but also
to fund the implementation of this program. Engineering Staff has worked tirelessly to map all the
impervious surfaces in the City with the exception of single-family dwellings. Staff presented a
recommendation to council to hire a consultant to assist us in the development and implementation of a
stormwater utility. Council awarded the Stormwater Utility setup to Dewberry Engineers and they have
developed the documents necessary to implement a stormwater utility. As of the writing of this report,
council action has not moved forward with respect to a Stormwater Utility but, the new City Manager has
slated this important funding stream on his agenda matrix. Stormwater quality and MS4 compliance for
the City of Henderson requires funding of two full time positions, collaboration with Public Works and
the hiring of part-time staff to assist in field data collection and reconciliation by GIS staff.
Henderson's Engineering Staff includes an engineering inspector that is certified for BMP construction
and maintenance and this individual has mapped and commented on the condition of existing SCMs
(BMPs) within the City Limits. The engineering inspector is also involved in the inspection and
construction of sedimentation and erosion control measure for which he generates weekly reports during
construction as well as the conversion of sedimentation devices to SCMs once the ground is stabilized.
The engineering inspector and city engineer talk throughout the project to make sure everything is
working smoothly so, by the time the final inspection takes place the revisions are very small. At the final
walk through the contractor, engineer of record, city engineer and engineering inspector draw up a final
punch list to get the site and all its components into compliance. This is a critical step in how the SCM
will perform and any additional modifications prior to the final approval.
Funding is a critical component in Henderson's stormwater program because it not only allows us to hire
staff but provides training, tools, money for capital improvement projects, hiring consultants with the
expertise to help Henderson develop and hone specific aspects of the program.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the City of Henderson as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The City of Henderson has evaluated residential car washing for
possible water quality impacts and determined wash water is absorbed by the surrounding yard.
The City performs street sweeping not street washing on only curb and gutter streets. A small amount of
water is used in the street sweeping activity on the order of 150 gallons per mile or 0.027 gallons/foot.
The vast majority of the water used in the street sweeping operation is bound to the refuse and vacuumed
up into the dump bed on the sweeper truck. Approximately 1,000 pounds of refuse is collected per mile
and discharged at the landfill.
The Division has not required that other non-stormwater flows be specifically controlled by the City of
Ienderson.
The City has an unusually high number of commercial car washes compared to the population for most
municipalities therefore, it is unusual to see residential car washing occurring and rarely does it spill into
the street or stormwater system. The discharges directly from residential home and car washing into the
MS4 is considered a possible source of impact to water quality. The City of Henderson shall make a
concerted effort via public education about the use of detergents and cleaners used in the washing of cars
and homes as well as their possible water quality impacts.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, the City of Henderson is aware of other significant
water quality issues within the permitted MS4 area.
The City needs to perform an environmental assessment on all water bodies within the City limits but the
most ubiquitous issues from a quick visual inspection is sediment and litter. The City monitors and
maintains certain thoroughfares in the City that accumulate litter, then dispatch crews to pick up the litter
before it migrates to our water bodies. Even with monthly or twice a month litter sweeps by Public
Works the crews cannot stay keep up with the litter. City Council and the City Manager have discussed
this problem at length in break-out committee meetings and at the City Council Strategic Retreat.
Council have requested fast food businesses to put in trash receptacles at the end of their drive-throughs
and to assist in the litter sweeps. The attempts by business are short lived and have very little impact. The
Police Chief has stated that no citizen throws out litter while an officer is behind them hence issuing
citations has not occurred and does not appear to be a viable solution to this problem.
Sediment accumulation in the streams appears from historical development of commercial enterprises and
single family housing. The City of Henderson does not issue erosion control permits for residential areas
unless the disturbance is in excess of 1 acre. While the City does not issue these residential permits, we
do monitor the measures in place and request certain maintenance items be performed to keep sediment
on -site. January 2015 to date the City Inspector has done an excellent job in notifying home builders of
DRAFT NCS000542 SWMP
City of Henderson
October 26, 2020
Page 11

l
the expectations and the City achieves complete compliance 95% of the time. The builders understand
the City's request for measures like silt fence, check dams and concrete washout pits therefore putting the
contractor on notice once we are award of the disturbance tends to lead to compliance because they know
we have them on our radar.
Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP, the
likely activities/sources/targeted audiences attributed to each pollutant, and identifies the associated
SWMP program(s) that address each. In addition, the City of Henderson has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

4.2 Program Funding and Budget
In accordance with the issued permit, the City of Henderson is required to provide adequate funding and
staffing to implement and manage the provisions of the SWMP and comply with the requirements of the
NPDES MS4 Permit. The budget includes the permit administering and compliance fee, which is billed
by the Division annually but, the program is underfunded with respect to the 6 prongs of compliance.
The stormwater program currently receives funding of approximately $25,000 per year for emergency
repairs and is funded primarily through the General Funds (Street Division). The street division has a
street sweeper and a jet -vac to clean the streets and stormwater pipes when they get clogged. The City
utilizes a work order system to help department heads schedule their work and assess the quality and costs
of each repair. Cartegraph is the name of the work order/asset management system and it has a
component to assign preventative maintenance for specific assets. The City's public works departments
plans to implement a program to clean at least 10% of the storm drains each year. The stormwater
program will be developed in the next year to mirror the existing sanitary sewer preventative maintenance
program. Currently public works dedicates 65 manhours a week to addressing the stormwater
infrastructure. As the stormwater program expands; the duties, responsibilities and manhours in the street
department will increase accordingly.
The administration of the city's stormwater regulatory side is performed by the City Engineer,
Construction Inspector and Engineering Technician which are funded through the Water Fund. In total the
stormwater program receives 5-6 hours a week from the engineering staff. The City of Henderson has
experienced only a small uptick in development over the last 7 years. Therefore, stormwater SCM review
and inspection is only a small component of the department's workload.
- Through the gap analysis, self -evaluation process and NCDEQ audit; it is evident that the City of
Henderson needs to fund a minimum of two full time position equivalents (FTE) which includes at least
two part-time positions for the stormwater program. The key position is a stormwater engineer to head -
up the program along with an administrative assistant (30%) and the City Engineer (20%) to guide and
>_ promote the program with the community and City Council. The part-time positions are critical in data
collection, mapping and assessment.
t
The City has performed an analysis to create a stormwater utility. The funding arm proposed for this
utility is based on a flat rate for residential (single and duplex occupancies) units. Fees for multi -family,
DRAFT NCS000542 SWMP
City of Henderson

t
industrial and commercial zoning is based on acreage of impervious area. Due to the nature of several
large businesses, the analysis showed that 13 businesses in the city would carry 65% of the Utility's fee.
Henderson is an old textile town that is still reeling from the economic downturn created by NAFTA and
k to impose a large monthly fee on these legacy businesses has become untenable to several members of the
City Council. Staff has gone back and revised Stormwater Utility Fee structure to impose a minimum and
maximum monthly fee where the maximum charge to an individual business would be $300 and a
$20/month minimum on every business. This minimum and maximum structure reduces the burden to
the large businesses and redistributes these costs on smaller businesses while providing the same revenue
stream as the initial impervious acreage fee to the City.
Additional staff via the stormwater utility will address the fundamental tenants of the stormwater
program. The self -audit that was composed by a consultant in conjunction with Henderson's engineering
staff indicates there are many deficiencies and work to be performed over the coming years. Current
market trends place a trained stormwater engineer in great demand by large and small municipalities as
well as large and small consultants. Henderson along with many other small municipalities without
stormwater utilities can barely afford an Engineering Intern much less a seasoned midlevel engineer with
5-10 years that would not require any training. The City Engineer has for the third year put a stormwater
engineer in the budget along with an administrative assistant and more money for part-time interns. The
City Manager has met with the City Engineer for the Fiscal Year 21-22 and understands the gravity of the
stormwater engineer. The manager also understands the funding mechanism to make this position a
reality.
4.3 Shared Responsibility
The City of Henderson does not share the responsibility to implement EPA's NPDES MS4 Permit
requirement. The City of Henderson remains responsible for compliance if we fail to perform our permit
obligation,

PART 9: POST -CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
This SWMP identifies the minimum elements to develop, implement and enforce a program to address
stormwater runoff from new development and redevelopment projects that disturb greater than or equal to
one acre, including projects less than one acre that are part of a larger common plan of development or
sale, that are located within the City of Henderson and discharge into the MS4. These elements are
designed to minimize water quality impacts utilizing a combination of structural Stormwater Control
Measures (SCMs) and/or non-structural SCMs appropriate for the community, to ensure adequate long-
term operation and maintenance of SCMs.
In accordance with 15A NCAC 02H .0153 and .1017, the City of Henderson implements the following
State post -construction program requirements, which satisfy the NPDES Phase II MS4 post -construction
site runoff control requirements as Qualifying Alternative Programs (QAPs) in the MS4 area(s) where
they are implemented.

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the City
of Henderson municipal facilities and operations. Pollution prevention and good housekeeping is
-' accomplished through the implementation of seven required programs, which collectively address the
ultimate goal of preventing or reducing pollutant runoff from municipal operations such as parks and
open space maintenance, fleet and building maintenance, new construction and land disturbances, and
municipal storm sewer system maintenance.
Pollution prevention and good housekeeping for municipal operations includes the following programs:
1. Municipal Facilities Operation and Maintenance Program
2. Spill Response Program
3. MS4 Operation and Maintenance Program
4. Municipal SCM Operation and Maintenance Program
5. Pesticide, Herbicide and Fertilizer Management Program
6. Vehicle and Equipment Maintenance Program
7. Pavement Management Program
The City of Henderson will manage, implement and report the pollution prevention and good
housekeeping SCMs as specified in Table 21 below for each required program.
Table 21: Pollution Prevention and Good Housekeeping BMPs
Permit
37.1: Municipal Facilities Operation and Maintenance Program

The City of Henderson has identified many gaps in our MS4 stormwater program and thru the GAP
Analysis and this Stormwater Management Plan we have a template to improve and build upon the
program that is already in place. The MS4 will require the dedication of staff from multiple departments
and financial resources from the City Manager and City Council. The tasks and schedule are ambitious,
multiple new positions will be required to make this program complete. The task ahead requires passion,
hard work and political clout but, the five-year window provided by NCDEQ should make this an
achievable program.
