4.2.5 Post-Construction Stormwater Management for New Development and Redevelopment
4.2.5.1 Permit Requirements
The post construction stormwater management program is designed to give the City of Greenville the authority to require structural and non-structural stormwater quality BMPs on sites being developed. The City of Greenville currently provides design requirements to control stormwater discharges from new development and redeveloped sites and has established performance standards for addressing the first inch of runoff. The City of Greenville will ensure post construction BMPs are inspected and maintained.
4.2.5.1. Post-Construction Stormwater Management Program:
The City of Greenville provides design requirements to control stormwater discharges from new development and redeveloped sites in the Stormwater Ordinance section “Stormwater Permits”. Currently, the City requires an “Erosion and Sediment Control Permit” for any development which disturbs 10,000 square feet or more. The City requires a “Minor Stormwater Permit” with applicable design requirements for sites that disturb between 1-2 acres. The City requires a “Major Stormwater Permit” with applicable design requirements for sites that disturb greater than 2 acres.
4.2.5.4 Long-Term Maintenance of Post-Construction Stormwater Control Measures:
All structural stormwater control measures installed and implemented to meet the site performance standards will be maintained in perpetuity. The City of Greenville will ensure the long-term maintenance of structural stormwater control measures installed.
The City of Greenville requires stormwater control measures to be maintained in perpetuity by requiring property owners to sign a Permanent Stormwater Facility Maintenance and Responsibility Agreement form.
4.2.5.5 Inventory of Post-Construction Stormwater Control Measures:
The City of Greenville will maintain an inventory of all post-construction structural stormwater control measures installed and implemented at new development and redeveloped sites, including both City permitted public and private sector sites located within the permit area. At a minimum, the inventory will contain all BMP constructed since the effective date starting with the effective date of this permit.
4.2.5.6 Inspections and Enforcement:
4.2.5.6.1 Inspection Procedures:
To ensure that all stormwater control measures are operating correctly and are being maintained as required consistent with its applicable maintenance agreement, the City of Greenville will conduct inspections of each project site covered under the performance standards listed in the Stormwater Design Manual, at least one time during the permit term.
4.2.5.6.2 Post-Construction Notification:
Within 30 days of completion of construction of any project required to meet the performance standards, the City of Greenville will conduct a post construction inspection to verify that BMP have been installed as per approved plans. The SCDHEC NOT form will serve as notification to the City of construction completion.
4.2.5.6.3 Inspection Reports:
The City of Greenville will document its inspection findings in an inspection report. The City of Greenville will document and maintain records of inspection findings and enforcement actions and make them available for review by the permitting authority.

Frequently Asked Questions
What water quality standard does my Greenville development need to meet?
The city has established performance standards focused on addressing the first inch of runoff from your site. The post construction stormwater management program gives the city authority to require both structural and non-structural stormwater quality best management practices (BMPs) to meet this standard.
Do I need to maintain my stormwater BMPs forever in Greenville?
Yes. Any structural stormwater control measure installed to meet the site’s performance standards must be maintained in perpetuity. To formalize this, property owners are required to sign a Permanent Stormwater Facility Maintenance and Responsibility Agreement, and the city itself works to ensure the long term maintenance of these measures continues. AQUALIS can help property owners build a maintenance routine that holds up over the long run.
Does the City of Greenville keep track of stormwater BMPs on private property?
Yes. The city maintains an inventory of all post construction structural stormwater control measures installed at new development and redevelopment sites, covering both public and private sector projects, dating back to the effective date of its current permit.
Will the City of Greenville inspect my stormwater facility after it's built?
Yes, at least once during the permit term, to confirm your facility is operating correctly and being maintained according to its maintenance agreement. Separately, within 30 days of finishing construction, the city conducts a post construction inspection to verify your BMPs were installed according to the approved plans.
Does the city document its stormwater inspection findings in Greenville?
Yes. The city documents its findings in a formal inspection report and maintains records of both inspection findings and any enforcement actions, making them available for review by the permitting authority.
Can I get a stormwater fee credit in Greenville, South Carolina?
Yes, if you’re a non-residential property owner. Stormwater credits are available for non-residential properties that maintain stormwater quantity and quality control measures. AQUALIS can help property owners document their BMPs to support a credit application.
