City of Greenville / County of Pitt

The City of Greenville has enacted a Stormwater Ordinance in order to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within this jurisdiction.  The City of Greenville is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Greenville will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The City of Greenville, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The City of Greenville has the authority to inspect stormwater facilities and practices in order to ascertain that they are properly maintained and functioning.

Pitt County Stormwater Ordinance for Nutrient Control

§ Section. 21 General Performance Criteria for Post-Construction Stormwater Management Controls.

The following performance criteria shall be addressed for stormwater management at all sites:

1. Stormwater runoff from the development shall be transported from the development by vegetated conveyances to the maximum extent practicable. The use of on-site stormwater treatment devices such as infiltration areas, bioretention areas, and level spreaders are recommended; and
2. All built-upon areas shall be at a minimum of 50 feet landward of all perennial and intermittent surface waters, unless a variance is obtained from the North Carolina Division of Water Quality. For the purpose of this ordinance, a surface water shall be present if the feature is shown on either the most recent version of the soil survey map prepared by the Natural Resources Conservation Service of the United States Department of Agriculture or the most recent version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United States Geologic Survey (USGS). Relief from this requirement may be allowed when surface waters are not present in accordance with the provisions of 15A NCAC 2B .0259 (3)(a).
3. Where the use of BMPs is necessary based on approved export calculations, projects shall be required to implement postconstruction stormwater management BMPs and shall conform to the following requirements:
   1. All site designs shall clearly indicate any proposed structural BMPs.
   2. All BMPs shall seek to use pervious areas for stormwater treatment and to infiltrate stormwater runoff from driveways, sidewalks, rooftops, parking lots, and landscaped areas to the maximum extent practical.
4. New development shall not discharge untreated stormwater directly into a jurisdictional wetland or water body without adequate treatment as determined by the Stormwater Administrator. Where such discharges are proposed, the impact of the proposal on wetland functional values shall not be greater than allowed by the Army Corp of Engineers (ACE) or the North Carolina Division of Water Quality (NCDWQ).
5. Structural BMPs shall be designed to:
   1. Meet the general engineering design criteria as listed in 15A NCAC 2H .1008(c).
   2. Meet all design requirements and pollutant removal standards included in the Design Manual except that any standards explicitly stated within this ordinance that are more stringent than the manual shall prevail, and
   3. Address the physical characteristics of the site including but not limited to:
      1. Topography (minimum 2 foot contours)
      2. Maximum Drainage Area
      3. Depth to Water Table
      4. Soils
      5. Slopes
      6. Terrain
      7. Vegetation, existing and planned
      8. Location in relation to environmentally sensitive features such as surface waters and wetlands.
6. All stormwater management practices shall have a landscaping plan detailing the vegetation to be used in conjunction with the BMP.
7. Any development proposing to operate or maintain an on-site wastewater treatment systems for domestic wastewater, including but not limited to septic tanks, shall submit evidence that such systems have been approved by Pitt County Environmental Health prior to release of a certificate of stormwater compliance and shall be required to submit a certification under seal prepared by a qualified professional that the system has been designed and installed to prevent fecal coliform contamination of surface waters to the maximum extent practicable.
8. Prior to site design, applicants are encouraged to consult with the Stormwater Administrator to determine if their project is subject to additional stormwater or land development design requirements.

§ Section.22 Maintenance of Best Management Practices.

1. Single-Family Residential
   1. For residential development, the developer shall maintain , per the requirements of the operation and maintenance plan/agreement, permanent nutrient control best management practices for two years following plat approval.
   2. For long term maintenance of required stormwater BMP’s and improvements per the requirements of the operation and maintenance plan/agreement, a homeowner’s association shall be incorporated in accordance with General Statute 55. Appropriate bylaws shall be prepared, and proposed covenants or deed restrictions which address maintenance, apportionment of financial responsibility, and enforcement shall be provided. The County Attorney shall approve the adequacy of these materials prior to final plat recordation. These materials shall be recorded at the same time as the final plat and shall be appropriately cross referenced in the County Register of Deeds office.
2. Commercial, Industrial and Multifamily
   1. For commercial, industrial or developments other than residential developments that require the installation of permanent stormwater management best management practices, the landowner shall be responsible for maintenance of such improvements per the requirements of the operation and maintenance plan/agreement.
3. The process for BMP maintenance enforcement shall be as follows:
   1. The County will annually inspect the BMP’s and send an inspection report to the appropriate party; if maintenance is needed, a deadline for corrective actions would be cited on the inspection report;
   2. If requirements of the inspection report are not met, the County may pursue legal action to bring the site into compliance, including civil and criminal penalties (Refer to Section 12 for the Enforcement Process)

§ Section.23 Operation and Maintenance Plan Required.

1. A written inspection and maintenance agreement shall be submitted by the applicant, approved by the Stormwater Administrator, and recorded in the Office of the Register of Deeds of Pitt County prior to release of a certificate of stormwater compliance. Such agreement shall:
   1. Be legally binding on all current and future parties in interest for all properties served by the BMP.
   2. Identify and describe the maintenance and monitoring operations required to insure the proper function of the BMP. Such operations shall be specific to each of the BMPs on the site and shall include, as appropriate, but shall not be limited to the following:
      1. Routine maintenance measures such as grass mowing and trash removal.
      2. Routine inspections of required vegetation.
      3. Routine maintenance thresholds such as maximum and minimum vegetation heights and coverages, maximum sediment storage capacity, proper drainage indicators, etc.
      4. Routine inspection of BMPs for sediment, blockage, and other repair/maintenance needs.
      5. Routine inspection of BMPs after large storm events for structural damage and other repair/maintenance.
      6. A schedule of expected significant repair/maintenance activities indicating the frequency of the activity, the expected duration of the activity, and the expected cost of the activity in current dollars.
      7. Maintenance actions and frequencies specified by practice in the Design Manual.
   3. Records of Installation and Maintenance Activities.
   4. The operation and maintenance agreement shall stipulate that parties responsible for the operation and maintenance of a stormwater management facility shall make and keep records of the installation and of all maintenance and repairs, and shall retain the records indefinitely. As long as records are maintained privately, they shall be made available to Pitt County or its agents during inspection of the facility and at other reasonable times upon request.

Non-Residential Customers

All non-residential customers will be charged $5.35 per 2,000 square feet of impervious cover existing on their property per month. Non-residential properties are all properties other than single-family and duplexes.

Example:

100,000 sf/ 2,000 sf = 50 ERU
50 ERU x $5.35 per month = $267.50 per month for the Stormwater Utility Fee
