Town of Holly Springs

The Town of Holly Springs 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 Town of Holly Springs 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 Town of Holly Springs will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The Town of Holly Springs, 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 Town of Holly Springs has the authority to inspect stormwater facilities and practices in order to ascertain that they are properly maintained and functioning.

SECTION 8.00 STORMWATER DESIGN

8.03 Post Construction Stormwater Management

1. Inspection Procedures

1. Schedule

Recommended inspection frequencies for SCM types:

• Quarterly and within 24 hours after every water quality storm (greater than 1.0 inch). Inspection must be conducted by a trained, qualified party. These inspections are intended to identify obvious maintenance needs early in order to prevent more extensive corrective actions.
• Annual Certification. Inspection must be conducted by a Professional Engineer. These inspections are intended to provide a more thorough assessment of the facility. Annual inspection reports (sealed by the PE) must be submitted to the TOHS Engineering Department. Field survey calculations to confirm storage volume and embankment stabilization, etc. may be required on a case by case basis.

2. Operation and Maintenance Log and Reporting

2. Maintenance Procedures

1. Initial Maintenance

Initial maintenance, to complete the construction of the BMP and monitor until plants are established, is needed for certain BMP features, and includes activities such as:

• After the first time fertilization to establish grass or other plants in BMPs, fertilizer will not be applied.
• Other final maintenance measures to ensure proper functioning

I. Emergency Maintenance

Emergency maintenance will often be required immediately after storms and other emergencies. This may include the following, as needed:

• Replanting and repairs to structures.
• Vegetation is likely to need at least minor repairs.
• Mosquito control should be considered if standing water poses health risks because of mosquitoes.
• Obstructions and debris deposited during storm events should be removed immediately. Exceptions include debris that provides habitat and does not damage vegetation or divert currents to, from, or in the BMP. Because of the high quality habitat that can be found in woody debris, careful re-positioning rather than complete removal may be desirable. There may be instances where debris is even added. Such locations should be noted so that this debris is not accidentally removed.
• If the basin of a BMP must be drained for an emergency or to perform maintenance, the flushing of sediment through theemergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical.

II. Corrective Maintenance

• All maintenance needs cited at quarterly, semi-annually and annual certification inspections must be addressed within 60 days of each inspection report unless noted circumstances dictate that it be done in a shorter timeframe.
• All corrective actions involving structural repairs or use of heavy equipment shall be coordinated and approved by the TOHS Engineering Department through notification prior to and following the corrective actions(s).
• Minor repairs do not require prior TOHS approval.

6. Operations and Maintenance Guidelines for Specific BMP Types shall meet the criteria outlined in the most current version of the most current NCDENR Stormwater BMP Manual.

The Phase II Post-Construction Stormwater Ordinance

DIVISION 4. - PERFORMANCE AND MAINTENANCE

1. Stormwater maintenance agreement (SMA). An executed SMA is required to establish and outline the requirements of the maintenance surety. The SMA shall be approved by the engineering department prior to the transfer of maintenance responsibility from the original applicant, permit holder, or owner to the association or owner(s). For all structural BMPs required pursuant to this article the required SMA shall include all of the following provisions:
