Stormwater Capital Improvement Projects
The Department of Environmental Engineering is responsible for the overall implementation of the county’s stormwater permit. The permit authorizes the county to discharge stormwater from the storm sewer system and requires the implementation of programs, such as the Capital Improvement Program, to manage stormwater and reduce pollutants discharged to local streams, creeks and lakes. The projects are selected based on a cost-benefit analysis documented in the Chesapeake Bay TMDL Stormwater CIP (PDF) and assist the county in meeting the permit requirements.
Information for projects scheduled for or under construction can be found by clicking on the project tab below. For more information on completed or future projects, please visit Capital Improvement Projects for Chesterfield County, Virginia under the Environmental Engineering tab.
Regional Stormwater Facility LTC 20/25 - Labyrinth Spillway
Control Measure: BMP Retrofit
Status: Plan Development
Completion: 2021
Coordinates: 37.458460/-77.485063
Receiving Stream: Falling Creek
Funding Year: 2017
Description
The Falling Creek Reservoir Restoration Project is the largest planned component of the county’s long-term Chesapeake Bay TMDL strategy. The reservoir has a watershed drainage area of about 34,000 acres, and 2 major tributaries, Falling Creek and Pocoshock Creek, enter the upstream end of the reservoir. The reservoir is part of the Chesapeake Bay watershed and water released through the dam drains to the James River, which is located about 2.5 miles east of the reservoir. Although the reservoir was originally constructed in 1951 for water supply storage, it has not been used for this purpose since 1985. It is estimated that about 84 million gallons (MG), or 28% of the original storage volume has been lost due to sedimentation. Continued sedimentation at the average historical rate of about 1.5MG per year contributes to additional degradation and reduces future potential pollutant reduction of the reservoir.
The drainage area into Falling Creek Reservoir was mostly developed before any stormwater management requirements were established. The reservoir restoration project is to enhance the reservoir’s efficiency for removal of nitrogen, phosphorus and suspended solids in order to improve water quality, downstream and in the Chesapeake Bay.
Updates
The project consists of a physical restoration of the reservoir with the construction of a forebay and berm and the removal of 120,000 cubic yards of sediment. Construction is planned to initiate in the fall of 2019 and continue for approximately 2 years. Click on the PDF below for the latest updates.

Control Measure: Stream Restoration
Status: Plan Development
Completion: 2021
Coordinates: 37.500202/-77.588163
Receiving Stream: Pocoshock Creek
Funding Year: 2014
Description
The Pocoshock Creek Stream restoration project is located in the area of Midlothian Turnpike and Sturbridge Drive in Chesterfield County. The stream restoration consists improvements to approximately 4,652 linear feet of stream channel (4,070 linear feet of main channel and 582 linear feet of side channel) The restoration will establish a geomorphically stable stream channel using natural channel design principles and reduce downstream nutrient and sediment loads and create aquatic habitat within the creek. The improvements will also provide for the ability to accommodate future flows and protect adjacent properties from flood damage.
