When it rains, we pour on technology mastery and innovative solutions for water challenges.

RESPEC’s professional  engineers specialize in stormwater and drainage engineering solutions for the urban environment. Our team designs and prepares construction plans for projects ranging from small, remedial drainage needs to major channel restoration. We deliver innovative techniques to convey runoff and reduce runoff volumes and pollutants while helping clients meet local, state, and federal requirements. Career experts in the fields of urban watershed hydrology, hydraulics, and water quality, the RESPEC team has successfully completed and delivered over 500 urban watershed projects.

RESPEC’s water-resource engineers specialize in hydrology and hydraulics planning and design services. Our projects cover the full spectrum of needs, from small stormwater analyses to multimillion-dollar design and construction projects. We perform hydrologic and hydraulic modeling by using SWMM, HEC-HMS, HEC-RAS, Flo-2D, and many other programs. RESPEC is adept at designing infrastructure in urban settings; we factor in public safety, property protection, channel stability, construction costs, multiuse potential, floodplain impacts, environmental constraints,  and  stakeholder concerns.

Experienced in watershed-level best management practice (BMP) planning and designing site-specific water quality BMPs, RESPEC can deliver any type of stormwater BMP design and construction-management service that may be required.  Our stormwater design projects culminate in construction drawings and specifications that provide integrated, cost-effective, and practical solutions that help our clients to protect surface water and groundwater quality.
