Waltham operates under an EPA MS4 permit and requires stormwater management plans for developments disturbing over 1 acre or adding significant impervious surface.
As an EPA-designated MS4 community, Waltham enforces stormwater rules under its Stormwater Management Ordinance and the MA Stormwater Standards. Any land disturbance of 1 acre or more, or redevelopment adding more than 5,000 square feet of impervious surface, requires a stormwater management permit from the Conservation Commission or DPW. Plans must include erosion and sediment controls during construction and permanent best management practices (BMPs) like detention basins, rain gardens, or infiltration systems post-construction. Illicit discharges to the storm drain system are prohibited, including wash water, paint, and chemicals. Stormwater flows eventually to the Charles River, which has TMDL requirements for phosphorus. Violations carry fines up to $5,000 per day under state law.
