How do I obtain a temporary construction dewatering permit?

The process of obtaining a construction dewatering permit is determined by the location of the site. Sites in combined sewer areas are required to obtain a permit from the Massachusetts Water Resources Authority. Sites within separated sewer and drainage area are required to obtain a Remediation General Permit from the United States EPA. Once an MWRA or EPA permit is obtained, the applicant may apply for a permit with the City of Cambridge. The entire dewatering application permit process generally takes 8 to 12 weeks.

How do I request assignment or verification of a street address?

All requests for assignment or verification of street addresses must be made in writing to Tracy Dwyer, Director of Engineering Services, TDwyer@cambridgema.gov. Requests are generally completed in 5 business days.
