Regulations at the federal, state, and local levels all require that stormwater management measures be implemented in order to address the quality and quantity issues associated with new development, redevelopment, and in some cases, existing development. Kleinfelder develops original site designs for low-impact developments that satisfy all regulatory requirements. Our approach to site planning for stormwater management is to integrate site design with engineering rather than adding design as an afterthought, as is so often done. The result is innovative stormwater engineering that satisfies all regulatory criteria in a manner that often saves money on construction and saves time. Kleinfelder provides not only drainage engineering design and calculations, but also design and construction oversight for individual Best Management Practices, such as constructed wetlands and bioretention facilities.
