INTRODUCTION
STORMWATER MANAGEMENT PLAN OVERVIEW
The North Carolina Division of Water Quality renewed NPDES Phase II Permit NCS000435 to
the City of Asheville effective February 17, 2017 – February 16, 2022. The Stormwater
Management Plan is the City of Asheville’s program to comply with NPDES Permit NCS000435
authorization to discharge Stormwater from Municipal Separate Storm Sewer Systems (MS4s)
located within the City of Asheville Jurisdictional Area.
The plan is a guidance document used by City staff and the general public.
STATUS OF IMPLEMENTATION
The City of Asheville is pleased to report progress for year eleven compliance with requirements
of NPDES Phase II permit in the following six measures in the plan:
● Public Education and Outreach
● Public Participation and Involvement
● Illicit Discharge Detection and Elimination
● Construction Site Runoff Control
● Post-Construction Runoff Control
● Pollution Prevention and Good Housekeeping for Municipal Operations.
On June 8, 2010 the City of Asheville Council approved Stormwater Ordinance No. 3875.
(Appendix A)
WATER QUALITY
The City of Asheville is delegated by the state to enforce the Stormwater, Erosion and Sediment
Control, and Illicit Discharge regulations within our jurisdictional area. The city has adopted and
enforces a stormwater, erosion control and sedimentation and illicit discharge ordinance.
(Section 7-12-2 of the Unified Development Ordinance) (Appendix B)
The city reviews and approves all development plans associated with grading, stormwater and
erosion control. For projects that are less than 10,000 square feet and greater than 500 square
feet, a sketch plan is required. A formal plan is required for projects that are 10,000 square feet
or greater. All formal plans are required to be prepared by a qualified registered NC professional
engineer or landscape architect.
For projects that disturb less than an acre and have 50 percent or less total impervious area of the
developed track and are not part of a larger development are exempt from the stormwater
ordinance. For all other project, stormwater controls must be designed by a licensed professional
and installed. The city requires 85% removal of Total Suspended Solids and also requires that
the post construction discharge not exceed pre-development discharge for the 2 year and 10 year
event. Within this ordinance, the city regulates a 30’ undisturbed buffer for construction
projects. All project have a buffer unless exempt by ordinance or have been previously
disturbed.
4
The city reviews plans and inspects construction activities inside the city limits. This is included
in the City's Unified Development Ordinance which regulates development. The city reviews
and approves development land use plans.
The city enforces a steep slope ordinance (Section 7-12-4) which limits total disturbed area based
on elevation and slope of the proposed development. The city regulates the special flood hazard
areas located within the city's jurisdictional area through our flood ordinance (Section 7-12-1).
This ordinance utilizes the latest flood maps and regulates development within this area.
(Appendix C)
State Programs: The state regulates projects that disturb over one acre that by state law cannot
be regulated by the City of Asheville.

The City of Asheville works with Environmental Quality Institute (EQI) for the testing of six
stream site samples within the city. EQI has been developing an on-going water quality database
of Western North Carolina watersheds. The purpose of the research is to continue and expand
the long-term monitoring of stream sites within Buncombe County. The cost is being shared by
the Buncombe County Soil & Water Conservation District (SWCD), Metropolitan Sewerage
District (MSD) and the City of Asheville Stormwater Services. The major focus of the
monitoring is to identify problem areas as well as areas with high water quality that need to be
maintained and to monitor areas where water quality improvement projects will be taking place.
This contract with EQI, offers technical assistance through laboratory analysis of samples and
statistical data analysis of monitoring results. Volunteers take these samples through EQI
Guidelines.
12
The overall goal of the proposed research is to assess the present water quality of representative
streams and rivers within the City of Asheville. Specific objectives include:
➢ Analyze water samples from six sites in Asheville for eight chemical parameters
monthly, with this contract it brings the total number of sites being tested in
Buncombe County to 47;
➢ Analyze the data statistically for trends between sites (spatial) and trends within sites
over time (temporal); and
➢ Use the results of the analyses to assess the ability of the streams to support their
various current, intended, and potential uses.
EQI laboratory analyzes all samples for the following parameters: pH, ammonia-nitrogen,
nitrate-nitrogen, orthophosphate, total suspended solids, alkalinity, turbidity, and conductivity.

The increase in runoff volume must be detained between 24-hours to 72-hours. Provided that the
stormwater administrator may require volume control for the difference between the
pre-development and post development volume of the 25-year 24-hour storm if by using existing
watershed master plan analysis it is found that that additional volume reduction is required to
protect downstream properties, natural and built drainage facilities due to the additional runoff
volumes from the 25-year 24-hour storm event.
Section 7-12-2 (f)(2)(a) calls for the run-off from the first one inch of rain to be detained
between 48 and 120 hours. Section 7-12-2(f)(2)(b) calls for all structural stormwater systems to

Accomplishment
The City of Asheville requires that all projects that involve a stormwater BMP have an Operation
and Maintenance (O & M) Agreement filed with the city and recorded in the Buncombe County
Register of Deeds office before a Certificate of Occupancy is issued. The agreement binds the
owner and any future owners. The agreement requires the owner to maintain, repair and if
necessary, reconstruct the structural BMP. It also grants the city a right of entry in the event that
the Stormwater Administrator has reason to believe that it has become necessary to inspect,
monitor, maintain, repair or reconstruct the structural BMP. The agreement states that if the
Stormwater Administrator has deemed an order directing the correction, repair, replacement or
maintenance of the facility has not been satisfactorily complied with within a reasonable period
of time the city may, after notice to the owner enter the land and perform any necessary work to
28
place the facility in proper working condition. The cost can be recouped by placing a lien on the
property or charging 150% of the cost for labor and materials.
In addition to the post-construction requirements, all private projects that involve the installation
of a stormwater BMP must have a private inspection contract between the financially responsible
person and an individual of equivalent licensure of the designer or certified specialist for
bi-weekly inspections of the installation of the BMP. The grading and stormwater permit cannot
be issued until this contract has been provided to the city.
The City of Asheville enforces a 30 feet wide undisturbed aquatic buffer along all jurisdictional
perennial or intermittent streams (7-12-2(f)(3)). The city does not currently have any designated
trout streams within our jurisdiction. Also, the city does not issue permits for any work in
conjunction with jurisdictional streams or wetlands without permits being issued by DWR or the
Army Corps of Engineers.
Section 7-11-4 of the UDO established the requirements for green space reservation in both
residential and non-residential developments in the city’s jurisdiction. For single family and
duplex subdivisions with lot size of one acre or more a minimum of 20% of the subdivision lot
area is to be reserved as open space. In other residential areas 500 square feet of open space per
unit or 15% of the lot area, whichever is greater, is to be reserved. Non-residential uses (schools,
churches) must reserve a minimum of 20% of lot area. For all non-residential areas excluding
the Central Business District 5 to 15% of the lot area is to be reserved.
The City of Asheville’s Public Works Department operates two vacuum trucks that clean out
storm drainage pipes and structures. The city operates these trucks on a cycle and inspects and
