Bowman provided planning, engineering, surveying, landscape architecture, and environmental consulting services within the 120-acre Lee District Park as part of the Family Recreation Area Spray Park and Accessible Tree House and Chessie Trail development. The accessible trails and tree house project had significant topographic and tree preservation challenges.

Bowman was hired as a primary engineering consultant, and completed the design, engineering and permitting for 17 miles of pipeline replacement. The majority of the designs were in major metropolitan cities or urban areas, with significant construction conflicts of other underground utilities. Included in the designs were the tie-in details, by-pass details, complete bill of materials, and service connections.

Bowman provided major upgrades to the Town of Broadway’s Water Treatment Plant. The upgrades included the installation of a state of the art 1.8MGD Pall Corp. MF membrane treatment system in a new concrete filtration building, upgraded and automated chemical feed systems, a 100,000-gallon well storage tank, and a 350,000-gallon finished water clear well.

Bowman partnered with English Construction for this Design-Build project for a central wastewater collection, treatment and disposal system to serve the service districts of Catlett and Calverton. The project includes a new collection system consisting of individual Septic Tank Effluent Pump (STEP) systems that transfer wastewater to a 80,000 gpd central wastewater treatment plant utilizing an Integrated Fixed Film Activated Sludge (FAS) technology. Effluent will be disposed of through the use of subsurface drip irrigation drain fields.

Bowman provided civil engineering, landscape architecture and surveying services for the second phase of this large redevelopment project consisting of multi-family housing with 157 townhouses and 176 apartment units, and an amphitheater and shade structure overlooking the Delaware River.

The project included the development of a retirement village with 1,500 independent living units and 512 assisted living and extended skilled care units located within 16 buildings on 232 acres.

Bowman provided planning, surveying and design services to the City of Colonial Heights for the Phase III and IV drainage and utility improvement plans of the Bruce Avenue Drainage Improvements project. This project included approximately 6,500 linear feet of city streets. The scope of the project included complete water, sanitary sewer and storm sewer replacement. The project also involved substantial excavation of the roadways within the ROW limits and rebuilding of new asphalt sections and curb and gutter.

Bowman provided its core planning and surveying services to design a complex extension of multiple large pipelines. The project was further challenged by sensitive environmental areas, tight easements, existing infrastructure, and ongoing mining activities.
