Stormwater Management

Increased storm water runoff from the development of land can, and often does, create serious issues that require engineering expertise to address. These issues revolve around runoff, particularly runoff quantity and water quality. Larson Engineering can design cost- effective Best Management Practices (BMP) to address these issues on your project.

Our experience with designing BMP’s for stormwater management includes design and implementation of runoff attenuation, detention, retention, groundwater recharge and erosion control, as well as many other methods.

At Larson Engineering, we plan, design, bid, and oversee construction of the BMP. We prepare plans and specifications for bidding, assist with obtaining the required permits and approval, and oversee construction to verify compliance with our designs.
