Section 9VAC25-875-660 - Comprehensive stormwater management plans

A VESMP authority may develop comprehensive stormwater management plans to be approved by the department that meet the water quality objectives, quantity objectives, or both of this part:

1. Such plans shall ensure that offsite reductions equal to or greater than those that would be required on each contributing site are achieved within the same HUC or within another locally designated watershed. Pertaining to water quantity objectives, the plan may provide for implementation of a combination of channel improvement, stormwater detention, or other measures that are satisfactory to the locality's VESMP authority to prevent downstream erosion and flooding.

2. If the land use assumptions upon which the plan was based change or if any other amendments are deemed necessary by the locality's VESMP authority, such authority shall provide plan amendments to the department for review and approval.

3. During the plan's implementation, the locality's VESMP authority shall document nutrient reductions credited to the BMPs specified in the plan.

4. State agencies and federal entities may develop comprehensive stormwater management plans and may participate in locality-developed comprehensive stormwater management plans where practicable and permitted by the locality's VESMP authority.
