Cambridge requires grading and drainage plans with building permits to ensure runoff is managed on-site and does not adversely affect neighbors or the municipal storm drain system.
Grading and drainage are reviewed by Cambridge Inspectional Services and DPW with every building permit. Site grading must direct runoff away from building foundations and neighboring properties. Finished grade cannot be raised to cause water to flow onto adjacent lots, which would violate common law and potentially the Sanitary Code. Larger projects require formal drainage plans showing downspout locations, grading contours, and connection to approved systems (typically infiltration, rain garden, or dry well before overflow to the MS4). Sump pump discharge to sanitary sewer is prohibited; discharge must go to a lawn area or storm system. Grade changes in the public right-of-way require DPW approval.
