Stormwater Detention

Design-build and installation of stormwater management systems for commercial and municipal applications.

Scope of Work

Our stormwater management services include construction of detention and retention facilities, permeable pavement systems, bioswales, and outlet structures. We work from engineering plans or provide design-build services in coordination with civil engineers.

Installation encompasses excavation, grading, liner systems, underdrain installation, outlet control structures, and final vegetation establishment. Our crews understand the critical relationship between grading tolerances and hydraulic performance.

Typical Project Types

Underground detention vault systems
Surface detention basins with landscaping
Retention pond construction and restoration
Permeable pavement parking areas
Bioswale and rain garden installation
Outlet control structure construction
Green infrastructure retrofits

Safety and Compliance Considerations

All excavations for detention facilities follow slope stability requirements based on soil conditions. Dewatering systems are employed as needed to maintain dry working conditions during construction.

NPDES compliance is maintained through erosion control measures and inspection protocols. Temporary stabilization is installed on exposed slopes pending final vegetation establishment.

Outlet structures are constructed in accordance with local drainage ordinances and watershed management plans. Flow control devices are tested and verified prior to system acceptance.
