Project Summary
Timmons Group has assisted James City County by providing the planning, design, environmental permitting and construction administration for the Ironbound Road Regional Stormwater BMP Project. This water quality BMP retrofit is located in a heavily urbanized portion of the College Creek Watershed. Identified as a much needed stormwater project for the watershed, the Regional BMP Project was proposed as a solution to support stormwater quality improvements as well as provide discharge quantity control in a watershed containing established residential and proposed new development.
The Regional BMP will work in conjunction with an existing sediment forebay to further the water quality support for the community. Supporting the engineering design of Timmons Group’s Stormwater Management Group, our Environmental Services Professionals completed preliminary environmental evaluations of the project area including a wetland delineation and U.S. Army Corps of Engineers (COE) confirmation, perennial stream assessments and resource protection area (RPA) identification, and Unified Stream Methodology (USM) channel condition assessments.
To support the Ironbound Road Regional Stormwater BMP Project and compensate for the direct stream impacts required for the project, Timmons Group designed, constructed, and is currently monitoring the Warhill Offsite Stream and Wetland Mitigation Site. During substantial design completion, Timmons Group hosted pre application coordinations with the COE, subsequently prepared the initial Joint Permit Application, and successfully negotiated a COE Individual Permit issuance to support construction of the Regional BMP Project.
