Fairfax County Civil Stormwater Management Task Contract
Little Hunting Creek Watershed, Fairfax County, Virginia
Bowman Consulting was retained under a Fairfax County Stormwater Division Task Order Contract to work on multiple drainage improvement projects in the Little Hunting Creek Watershed.
The scope of services included establishing vertical and horizontal control using GPS for aerial topography while annotate topography was prepared by a cartographer. Bowman Consulting’s team of field surveyors used a combination of conventional methods in dense areas and aerial topography to complete the survey. Additionally, as-built storm sewer and sanitary sewer surveys were provided along with the preparation of easement plats. All data was compiled and a base sheet was created. The project also included civil engineering design to correct existing problem drainage areas such as those found in the Derek Road area.
After evaluating the site and the problem area, Bowman Consulting proposed alternative solutions along with conceptual cost estimates. Task orders included multiple low-impact-development (LID) retrofits of existing facilities in the watershed.
Bowman Consulting coordinated extensively with the following Fairfax County sites, along Little Hunting Creek, which were affected by this work:
- Bucknell Elementary School Park
- Carl Sandburg Middle School
- Collingwood Park
- Fort Hunt Elementary School
- Hybla Valley School
- Sherwood Hall Regional Library
Currently, Bowman Consulting is developing conceptual LID plans and final design documents for the retrofits. Bowman Consulting is also developing graphic presentation boards for signage or LID concepts as requested by the Stormwater Planning Division.
