3. MS4 Conveyance System
The City of Hendersonville’s storm water system is a combination of curb and gutter
systems, various sizes and types of pipes and open drainage ways or ditches on local,
State and private roads. The City maintains City roads and curb and gutter systems within
the City Limits. Some of these tie in to drainage systems on State roads, but most of the
City storm water system drains into receiving streams.
The State DOT maintains systems along the State Roads such as US 25, US 64, NC 191
and NC 176 as well as a number of other streets and roads within the City. Reference is
made to the current Powell Bill map for their names and locations.
There are private drives and small roadways that are both paved and unpaved and that
connect to City and State roads and are maintained by owners. Most of these utilize open
ditches for stormwater control.
City maintenance includes leaf and garbage pickup, yard waste and brush removal, street
sweeping, and storm-drain clearing. Public Works staff will respond to complaints on storm
drains and clean out pipes and drains as needed with shovels, rakes, or other machinery.
Hendersonville’s Public Works Department currently maintains 40 full time employees.

13. PUBLIC EDUCATION AND OUTREACH PROGRAM

To meet this requirement the City implements a public education program to distribute
educational materials to the community and conduct outreach activities to educate the
public on the impacts of Stormwater discharges on water bodies. Educational efforts
include steps the public can take to reduce pollutants in storm water run-off. To
accomplish this, the City will continue to:

Target Pollutant Sources:

• Sediment and erosion because of the increase in new and redevelopment projects
during previous permit cycle and the likelihood of future development projects
• Automotive pollutants from roads and parking lots due to impervious surface area
within the City’s urban area
• Household and yard waste because of high residential to commercial/industrial
properties in the City
• Illicit discharge from poorly maintained dumpsters and trash compactors within the
City’s jurisdictional area
• Fertilizers and pesticides because of the agricultural areas draining to the waters within
the City
• Chlorinated pool discharge from large public pools.

Target Audiences that will have stormwater impacts:

• Builders, developers, and contractors whose work practices have the potential to
increase sediment and erosion.
• Local businesses and industries whose practices could contribute to pollution of water
and/or waste of water resources.
• Homeowners/ condominium associations, landscaping companies, and landowners
who are responsible for the operation and maintenance of a majority of the structural
BMP’s within the City’s jurisdiction and whose lawn and landscape practices can
negatively impact stormwater quality.
• Grade school through college students who can learn about the connection between
stormwater runoff and water quality at an early age, potentially affecting future
practices.
• Pool operators who have the potential to release chlorinated pool water into storm
drain systems.

8

Education and Outreach Program

• Sedimentation and Erosion – The City has applied for grants to fund several
streambank stabilization projects in the coming year. Additionally, previous streambank
restoration projects on Mud Creek and Brittian Creek provide educational signage
about stream restoration, sedimentation and erosion control, and the importance of
protecting our streams. The City will continue to properly maintain City owned property
to ensure they are not adversely contributing to sedimentation levels in local creeks
and streams.
• Automotive pollutants from parking lots -- Educational Materials will include information
about the pollutants from parking lots and how to implement run-off controls in parking
lot designs.
• Household and yard waste – The City will try to ensure that residents do not dump
hazardous materials, yard waste, brush, cleaners, automobile oil or antifreeze, etc. into
the storm drains.
• Leaking dumpsters and trash compactors – The City will distribute educational material
to local property/business owners about the proper maintenance of dumpsters and
trash compactor near storm drains.
• Fertilizers and pesticides – Property and business owners will be provided information
on the proper storage and use of pesticides and fertilizers. City Water and Sewer,
Parks and Maintenance staff have received NC Department of Agriculture training on
pesticide use and storage and they along with the appropriate Public Works staff will
continue to be kept up to date though training and educational materials on the use of
fertilizers and pesticides.
• Fecal Bacteria -- Residents will be provided with information on the proper disposal of
pet waste, kitty litter, etc. as part of regular solid waste informational materials
distributed by the City and included in signage within City parks.

• The City will continue to explore the feasibility of regional approaches to the
development and distribution of public educational materials and/or utilizing any
statewide education or outreach programs, and continue to develop a public materials
distribution plan. Informational materials will be made available at City Hall, the City
Operations Center, and on the City website.

• The City will continue to work with local resources including the Land-of-Sky Regional
Council, MountainTrue and other local agencies and organizations to develop local
training and educational materials for the public, landscapers, developers, schools, and
other target audiences. The materials will include topics such as Phase II
Requirements, Parks and Recreation Maintenance, Low-Impact Design, Watershed
Planning and Protection, or Habitat and Stream Restoration. Training activities will be
ongoing.

9
• Continue to revise and improve the City’s website by providing additional educational
materials on stormwater impacts, water quality, and pollution reduction.

Public Education and Outreach

BMP Measurable Goals
Continue and improve
upon public materials
distribution plan
Increase public awareness of the connection between improving water
quality and improving their quality of life, recreational opportunities,
scenic amenities, community value, property value, and public health by
distributing educational flyers/brochures annually at local festivals and
fairs and continuously at City Hall and the City Operations Building. This
goal will be measured by how many educational flyers/brochures are
distributed.
Develop and promote
public training
opportunities
Work with local resources such as the Land-of-Sky Regional Council, the
Environmental Sustainability Board, Henderson County soil and water
conservation, MountainTrue and other local organizations to develop
local training and educational materials for the public, landscapers,
developers, schools, and other target audiences. Hold a public training
session annually. This goal will be measured by gauging public support
and training attendance.
Use streambank
restoration projects as
water quality teaching
tools.
The City will continue to construct streambank restoration projects as
funding allows and use these projects to educate the public on the proper
ways to maintain a riparian stream buffer and improve water quality. The
City will develop educational materials for the website and/or signage
along existing projects and for future stream bank stabilization projects to
begin in 2016. Future teaching opportunities will be ongoing throughout
the permit, but only as funding allows.
Improve and update
the City’s stormwater
informational website
Continually provide additional educational materials on stormwater
impacts, water quality, and pollution reduction, including audio and video
files. Web traffic at the City’s stormwater education website will be a
measure of this goal.

10
14. Public Involvement and Participation

The City will implement a Public Involvement and Participation program to provide
opportunities for the public, including major economic and ethnic groups, to participate in
program development and implementation. The City of Hendersonville will meet these
requirements by doing the following:

• Continue to seek input and provide updates on Phase II requirements and
implementation to City Council and the City Planning Board as part of regularly
scheduled public meetings. May include at least one (1) annual public meeting with
stormwater related issues as an agenda item.

• Continue to arrange local scout troops and others to place educational vinyl placards
on existing City stormwater catch basins and curb inlets to inform the public that the
storm drains are not for waste disposal. Stencils have already been placed on many
structures and this action will be ongoing.

• Promote local “Adopt-a-Stream”, “Adopt-a-Creek”, and “Adopt-a-Drain” programs in
coordination with RiverLink, MountainTrue, scout troops, or other local resources. This
will provide opportunities for the public to participate in implementation of the
stormwater program.

• Develop educational material to present at local schools or community events to
promote public involvement in water quality issues and stormwater projects in the City.

• Promote annual stream clean-up events to enhance local stream quality.
11

Public Involvement and Participation

BMP Measurable Goals
Continue to seek input
from and provide
information to the
public
Continue to seek input and provide updates on Phase II requirements
and implementation to City Council as part of regularly scheduled
public meetings. This will be continuous during the permit period and
include a public meeting with stormwater related issues as an agenda
item annually.
Continue to arrange
local scout troops and
others to place
educational
stormwater vinyl
placards on City catch
basins and curb inlets
Previously placards were placed on many structures, but some need
to be replaced. The structures will be evaluated and stencils will
begin to be replaced/added throughout the permit cycle.
Promote local
“Adopt-a-Stream”,
“Adopt-a-Creek”,
and “Adopt-a-
Drain” programs
Promote through the City’s website a local “Adopt-a-Stream”, “Adopt-
a-Creek”, and “Adopt-a-Drain” programs in conjunction with
RiverLink, MountainTrue, scout troops, and/or other local resources.
This will provide opportunities for the public to participate in
implementation of the stormwater program and will be ongoing.
Develop educational
programs for local
schools
Develop an educational presentation that can be implemented at
local schools or community events to promote involvement in water
quality issues and stormwater projects in the City.

12
15. Illicit Discharge Detection and Elimination Plan.

The City will implement and enforce a program to detect and eliminate illicit discharge
within the MS4

Storm Sewer System Map:

The City’s Stormwater Quality Specialist has developed a map including outfalls,
drainage areas, and receiving streams using City of Hendersonville, Henderson
County, State of North Carolina, and USGS GIS data as well as GPS technology.
The map is continuing to be updated to include stormwater management BMP’s and
stormwater infrastructure.

Regulatory Mechanism:

The City adopted an illicit discharge violation and fine provisions as part of its
NPDES Phase II Stormwater Ordinance.

Enforcement:

The City’s NPDES Phase II Stormwater ordinance contains enforcement procedures
including notification of illicit discharge violators and potential fines for guilty parties.

Detection and Elimination:

A desktop assessment of illicit discharge potential has been completed to determine
the potential severity of illicit discharges within the City and identify which
subwatersheds require priority investigation. The desktop assessment consisted of:

• Delineating subwatersheds
• Compiling available mapping and data for each drainage unit
• Using GIS analysis to derive illicit discharge potential screening factors
• Screening and ranking the subwatershed illicit discharge potential
• Generating maps to support field investigations

The screening factors from the GIS data included density of industrial sites, age of
subwatershed development, number of stream miles in the subwatersheds, age of sewer
infrastructure, and density of sanitary sewer overflows.

Once the desktop assessment was completed, maps of priority areas were generated and
field screenings were performed utilizing an Outfall Reconnaissance Inventory (ORI). The
ORI consisted of stream walks to inventory and measure storm drain outfalls, and find and
correct continuous and intermittent discharges.

Methods used to eliminate any discovered illicit discharges will vary depending on the type
and location of the problem. These methods could include service lateral disconnection;
cleaning of the line; excavation and pipe replacement; manhole/catch basin repair;
pipe/structure grouting; or some type of in-place pipe repair (including pipe bursting, slip
lining, cured-in-place pipe repair, etc.).The cost of such work will be the responsibility of the
property owner deemed responsible for the illicit discharge.

13
Evaluation of the illicit discharge detection and elimination plan includes a comprehensive
tracking system consisting of updated mapping to reflect outfalls discovered during the
ORI; surveyed stream reaches with locations of obvious, suspect, and potential
discharges, and dumping sites; number of discharges corrected; status and disposition of
enforcement actions. Regular review of the tracking system will reveal strengths and
weakness of the plan, and this information will be used to improve the program.

Non-Stormwater Discharges:

The City’s NPDES Phase II Stormwater Ordinance specifically allows non-stormwater
discharges such as drinking water line flushing; discharge from emergency firefighting
activity; irrigation water; diverted stream flows; uncontaminated ground water;
uncontaminated pumping ground water; discharges from potable water sources; residential
foundation/footing drains; air conditioning condensation; uncontaminated springs; water
from crawl space pumps; individual non-commercial car washing operations; flows from
riparian habitats and wetlands; and street wash water provided they do not significantly
impact water quality.

Outreach:

The City will inform public employees, businesses, and the general public of hazards
associated with illegal discharges and improper disposal of waste through utility mailers,
the City newsletter, and on the City’s website. This outreach will be coordinated with and
included in the public education and pollution prevention/good housekeeping minimum
measure programs.

Staff Training:

The City will periodically screen training videos on illicit discharge detection to public works
and utility staff. If employees detect illicit discharges while in the field they will report them
to the Engineering Department using standard reporting forms.
14
Illicit Discharge Detection and Elimination Evaluation:

BMP Measureable Goal
Stormwater system
mapping
The City’s Stormwater Quality Specialist developed a map of the
storm system including outfalls, drainage areas, and receiving
streams using City of Hendersonville, Henderson County, State
of North Carolina, and USGS GIS data, as well as GPS
technology. The map will be improved over time to include illicit
discharges and updated stormwater management BMPs.
The initial map is complete and will be maintained and updated
throughout the permit period.
Desktop assessment of
illicit discharge
potential
A desktop assessment of illicit discharge potential was
completed to determine the potential severity of illicit discharges
within the City and identify which subwatersheds required priority
investigation. This will be updated and refined throughout the
permit period.
Field screen outfalls Field screening has been performed utilizing an Outfall
Reconnaissance Inventory (ORI). The ORI consisted of stream
walks to inventory and measure storm drain outfalls, and find
and correct continuous and intermittent discharges. The ORI
was completed for every stream mile or open channel during the
permit cycle. Annual review and sampling of suspect or potential
illicit discharges will be completed annually throughout the permit
cycle.

Conduct staff training The City will provide training (videos, etc.) to public works and
utility staff in discovering and reporting illicit discharges at least
annually.
Illicit discharge/illegal
dumping web reporting
tool
A web reporting tool for citizens to report illegal dumping and
suspicious discharges is advertised on the City’s stormwater
website and annually via utility bill inserts.

15
16. Post-Construction Stormwater Management in New Development and Redevelopment.

The City will continue to implement and enforce a post-construction stormwater
program to address stormwater runoff from new development and redevelopment
projects that disturb greater than or equal to one (1) acre, including projects less than
one (1) acre that are part of a larger common plan of development or sale, that
discharge into the City’s ETJ.

The City’s program requires all projects falling under these categories to apply for
permit coverage, which requires stormwater management controls that are designed,
constructed, and maintained in accordance with the latest edition of the North Carolina
Division of Water Quality Stormwater Best Management Practices Manual.

The Henderson County Environmental Health Division has oversight authority over
operation and maintenance of on-site wastewater treatment systems with the City of
Hendersonville. The City will coordinate with Henderson County as necessary for this
program.

Regulatory Mechanism:

The City adopted a post-construction stormwater management program as part
of its NPDES Phase II Stormwater Ordinance.

Operation and Maintenance:

The City’s post-construction stormwater management program requires that an
operation and maintenance agreement is executed and recorded with each
development and redevelopment project. This agreement requires the property
owner to maintain, repair, and, if necessary, reconstruct all structural BMPs
and/or other stormwater controls. The City’s program requires the property
owner to submit an annual inspection report to the City, which is to be completed
by a qualified professional.

The City requires that selected BMPs draining to trout waters do not result in a
sustained increase in the receiving water temperature. The City does not contain or
have any areas within its jurisdiction that drain to Nutrient Sensitive Waters.

Non-structural BMPs:

The City has adopted a Comprehensive Master Plan that incorporates several
initiatives, including:

• Encouraging infill development and redevelopment that utilizes existing
infrastructure in order to maximize public investment and revitalize existing
neighborhoods.
• Creating an interconnected network of green infrastructure that preserves
environmentally sensitive area, protects water resources through low-impact
stormwater management, provides floodwater storage, and provides
community open space and recreational opportunities.
• Encouraging community open space in new and/or redeveloped residential
neighborhoods; developing City-owned vacant parcels into pocket parks; and
16
acquiring and developing parkland within environmentally sensitive areas such
as stream corridors.

• Preserving environmentally sensitive areas and land adjacent to streams in
order to protect water quality, reduce erosion, and protect wildlife habitat.

The City has a Stream Buffer Protection ordinance, which maintains at least thirty (30)
feet of undisturbed vegetated area from both banks of all “blue line” streams within the
City’s jurisdiction as shown on the latest USGS mapping.

Natural Resource Protection:

The City’s Stream Buffer Protection ordinance requires at least 30 feet of undisturbed
vegetated area from both stream banks and an additional 20ft of vegetated transitional
area which helps to improve and protect water quality.

The City’s Comprehensive Master Plan also calls for preservation and restoration of
floodways and floodplains in an undisturbed, vegetated state to preserve flood storage
capacity, control the quality and quantity of stormwater, and preserve flora and fauna
habitat.

Tree Preservation:

The City’s zoning ordinance has requirements for street trees and other landscaping
within urban areas and contains provisions recommending preservation of existing
trees and vegetation. The Stream Buffer Protection ordinance prohibits removal of
trees and other vegetation within the buffer area.

Redevelopment & Development in Areas with Existing Infrastructure:

The City’s Comprehensive Master Plan contains provisions for encouraging infill
development and redevelopment that utilizes existing infrastructure in order to
maximize public investment and revitalize existing neighborhoods.

Mixed-Use Development:

The City’s Comprehensive Plan outlines new land use provisions concentrating retail
in dense, walkable, mixed-use nodes located at major intersections in order to
promote a sense of community and a range of services that enhance the value of
Hendersonville’s neighborhoods. This would encourage mixed-use, walkable design
through redevelopment and infill projects.

Street Design:

The City’s zoning and subdivision ordinances offer ranges of street types depending
upon the development. The overall goal is to minimize impervious area while
maintaining sufficient access for emergency vehicles. The City’s Comprehensive
Master Plan promotes the use of narrowed streets with bike lanes, landscaped
medians, and on-street parking.

17

Green Infrastructure Elements & Street Design:

The City’s ordinances do not yet integrate green infrastructure elements and street
design, but may in the future, especially as various provisions in the Comprehensive
Master Plan are implemented.

Reduced Parking Requirements:

The City’s ordinances do not yet integrate reduced parking requirements, but may in
the future.

Transportation Demand Management Alternatives:

Transportation demand management alternatives have not yet been addressed in the
City’s ordinances.

Minimizing Stormwater from Parking Lots:

The City’s zoning ordinance requires landscaping, buffers, and screens with newly
developed or redeveloped properties. This landscaping can be installed as part of a
parking lot.

Green Infrastructure Practices:

The City’s water restrictions ordinance as the as the water rate structure, in general,
encourage water conservation and therefore, the use of rain barrels, harvested rain
water, and other stormwater reuse for irrigation and other non-potable uses. Early in
the stormwater management plan review process, site plans are examined, and if
possible, alternative/green infrastructure is encouraged.

Maintenance/enforcement:
The City is establishing a tracking database for stormwater management systems.
Inspection reports are required to be completed annually with specific maintenance
steps for each structural BMP. City staff complete periodic inspections to verify BMP
and overall stormwater management system performance.

Green Infrastructure Strategies:

The City will revise ordinances and stormwater management requirements as green
infrastructure is continuously developed and advanced over the coming years.
18
Post-Construction Stormwater Management in New Development and Redevelopment
Evaluation

BMP Measurable Goal
Enforce post-construction
stormwater management
program
All development and redevelopment projects that disturb over
one (1) acre must submit a stormwater permit application,
appropriate fees, and checklists to be approved prior to any
construction activities.
Continued operation and
maintenance of structural
stormwater controls
Currently, an operation and maintenance agreement is executed
and recorded with each development and redevelopment project.
This agreement requires the property owner to maintain, repair,
and, if necessary, reconstruct all structural BMPs and/or other
stormwater controls. The City requires the property owner to
submit an annual inspection report to the City, which must be
completed by a qualified professional. The City’s recently hired
Stormwater Quality Specialist will be trained to conduct all
inspections annually during the next permit cycle.
Control sources of fecal
coliform
to the maximum extent
practicable
The Henderson County Environmental Health Division has
oversight authority over operation and maintenance of on-site
wastewater treatment systems with the City of Hendersonville.
The City will coordinate with Henderson County as necessary for
this program.
Establish trout water
protection
The City requires that selected BMPs draining to trout waters do
not result in a sustained increase in the receiving water
temperature. This is a continuous and ongoing component of the
post-construction stormwater management program.

19
16.1 Inspection and Maintenance of Municipally-owned facilities.

The City has developed and implemented an operation and maintenance
program for municipally-owned facilities that included an annual inspection
component, training for municipal staff, and a maintenance schedule that has the
ultimate goal of preventing or reducing pollutant runoff from municipal
operations.

Affected Operations:

The municipal operations impacted by this operation and maintenance
program include vehicle washing, automotive maintenance, materials
storage, road and park maintenance, stormwater facilities maintenance, and
sewer and water line installation and repair activities. Vehicle washing and
maintenance occur in Public Works department’s maintenance garage. Park
maintenance occurs on City park properties. Other municipal operations
described above take place throughout the City.

Maintenance and Inspection:

Public Works personnel maintain City park properties daily. All garbage
cans, picnic tables, dugouts, stands, and other park amenities are
anchored. Restrooms and concession stands are contained within
permanent structures.

Public Works motor pool personnel are in the maintenance garage daily and
follow a routine maintenance schedule. Public works staff also respond as
needed to complaints or maintenance needs. Random inspections are
conducted by the City’s Stormwater Quality Specialist at the motor pool,
maintenance garage, and materials storage area to ensure compliance with
current stormwater pollution prevention practices,

Vehicular Operations:

The City of Hendersonville fleet includes 140 insured vehicles, including
passenger cars and various types of trucks.

Light vehicle maintenance (oil changes, tire rotation, etc.) and some
significant maintenance for City vehicles is performed at the maintenance
garage, which is enclosed and protected. Used oil is collected for recycling
and stored in a covered and anchored tank with a concrete spill basin. This
basin is checked regularly and after rains for any evidence of seepage or
leaks. Other significant automotive repair for City vehicles is done utilizing
local private mechanic services.

There is a covered wash bay (which utilizes reused rainwater) for City
vehicles located behind the maintenance garage with an oil water separator.

20
