Service Description: This dataset is a selection of known erosion and flooding problems throughout the County. The data is intended primarily to assist site plan preparers with establishing the existence of known erosion and flooding problems.
Increased volumes of sheet flow that will cause or contribute to erosion, sedimentation, or flooding of down gradient properties or resources shall be diverted to a stormwater management facility or a stormwater conveyance system that conveys the runoff without causing down-gradient erosion, sedimentation, or flooding per Stormwater Management Ordinance 124-4-4.E. Minimum Standard (MS) 19 of the Virginia Erosion and Sediment Control Regulations (9VAC25-840-40.19) requires stormwater discharge from permitted projects be diverted to an adequate conveyance or detention facility.
This data documents known inadequacies in the stormwater conveyance system. Plan preparers should and County staff will use this information when evaluating compliance with requirements to discharge storm water to an adequate system or detention facility.
The erosion and flooding problems identified in the layer were determined using the following county datasets:
•Stream Physical Assessment 1.0 Erosion
•Stream Physical Assessment 1.0 Reach Habitat
•Stream Physical Assessment 1.0 Head Cuts
•Stream Physical Assessment 2.0
•Open Channel Inspections
•Stormwater Planning Division Investigation
