Stormwater Management Ordinance

Fairfax County has adopted a Stormwater Management Ordinance in response to state regulations requiring localities to adopt ordinances and take over reviews and inspections for Virginia Stormwater Management Program (VSMP) general permits relating to stormwater runoff from construction sites effective July 1, 2014.

Many processes, systems, ordinance changes and training of staff and industry, in addition to a written stormwater management ordinance, will need to occur in order for us to be ready by the effective date. A series of meetings with stakeholders was held to gather information that was used in developing the new county ordinance and design and construction standards for stormwater control practices.

On Sept. 10, 2013, the Board of Supervisors authorized advertisement of the following code changes: Adoption of Chapter 124 (Stormwater Management Ordinance), repeal of Chapter 105 (Pollution of State Waters) and 106 (Storm Drainage), and proposed amendments to Chapters 101 (Subdivision Ordinance), 104 (Erosion and Sedimentation Contol), 112 (Zoning Ordinance), 118 (Chesapeake Bay Preservation Ordinance), and Appendix Q (Land Development Services Fees) of The Code of the County of Fairfax, Virginia. The new ordinance and proposed amendments implement the Virginia Stormwater Management Act (Va. Code Ann. § 62.1-44.15:24, et seq.) and Virginia Stormwater Management Program (VSMP) Permit Regulations (9 VAC 25-870 et seq.)

A public hearing was held by the Planning Commission on Oct. 9, 2013; the Commission took action on Nov. 21, 2013. The Board of Supervisors Public Hearing occurred on Jan. 28, 2014.

This page will be updated with meeting dates, draft ordinances and other related information. Members of industry and the general public are encouraged to provide input as the county moves through the process of implementing the Stormwater Management Ordinance.
