Dry Detention Water Quality Enhancement Project

The Project consists of retrofitting existing stormwater detention basins including constructing forebays to increase pretreatment of solids and create sheet flow through the basin, removing and replacing of existing turf grass in the bottom of the basins with a hardier herbaceous vegetative mix that provides more treatment, and modification of outlet structures of basins that increase retention time within the basins to increase pollutant removal.

Construction Manager at Risk for Robinson Church Road Phase 2

Construction Manager at Risk  (CMAR) Services

A CMAR will bring value in determining the most cost-effective alignment and provide potential construction phasing options, thereby minimizing schedule risks and constructability concerns.

The proposed design includes a 12’‐wide concrete shared‐use path along one side of Robinson Church Road, beginning at Plott Road (connects to Robinson Church Road Phase 1 Improvements) and continues to Harrisburg Road. Accommodations for pedestrian / bicycle crossings and minor upgrades at major intersections (Hood Road, the future Eastern Circumferential Roadway and Harrisburg Road) and minor side streets (Alanbrook Road, Ludell Lane, Irwin Road, Fairford Drive, Solares Drive, Jerimoth Drive, Culver Spring Way, Hammond Drive, Atlas Cedar, Deluca Drive, Castle Garden Lane, Williams Gate Lane and Jones Creek Circle) will also be included in the scope. The project team is early in the design phase and plans are currently at a 10% milestone level. The CMAR shall provide input on the design, including side‐of‐street analysis for the shared‐use path and pedestrian / bicycle crossings at all major and minor intersections to identify potential cost savings and schedule efficiencies.
