Cambridge Stormwater and Soil Cleanup Bylaws

Cambridge, Massachusetts requires controls on stormwater discharges and responsible handling of contaminated soil at construction and redevelopment sites to protect waterways and public health. This guide summarizes the city departments involved, what triggers permits or management plans, how to report illicit discharges or suspected contaminated soil, and the practical steps property owners, contractors, and consultants should follow to comply.

Scope & Key Rules

The City of Cambridge regulates stormwater through municipal programs that implement federal and state requirements for runoff control, illicit discharge detection, and post-construction stormwater management. For contaminated soil and groundwater issues, state cleanup law and technical requirements apply alongside city site controls and disposal requirements. For city stormwater contacts and program details, see the Cambridge Public Works stormwater page Cambridge Public Works - Stormwater^[1]. For Massachusetts state cleanup and stormwater program guidance, see MassDEP resources MassDEP Stormwater Program^[2].

When Rules Apply

• Construction or site work that disturbs soil, changes grades, or alters drainage.
• Demolition, redevelopment, or material stockpiling that could produce contaminated soil or runoff.
• Any observed illicit discharge to catch basins, drains, or Cambridge waterways.

Permits, Plans, and Best Practices

Typical compliance items include erosion and sediment controls, stormwater management plans, and on-site soil management or disposal plans prepared by qualified professionals. Developers should include construction-phase controls and long-term post-construction measures in permit applications when required by the city.

Penalties & Enforcement

Enforcement for stormwater and soil handling in Cambridge is carried out by city departments with regulatory responsibility, typically Cambridge Public Works and Inspectional Services, which investigate reports, issue orders, and require corrective actions. Where contamination is governed by state law, MassDEP may have parallel enforcement authority.

• Escalation: first, repeat, and continuing offence treatment is not specified on the cited Cambridge stormwater page; local enforcement procedures and timelines are set by the enforcing department.^[1]
