Driveway & Parking Lot Paving

Parking Lot Drainage Retrofits
Stormwater controls must be installed during the resurfacing of any parking lot over 5,000 square feet in surface area.
Street Opening Moratoriums
The Town of Watertown maintains a moratorium on street opening activities between November 15 and April 15. Any exceptions must be approved at the discretion of the Superintendent of Public Works.
Roads paved within the past five years are subject to a street opening moratorium, except in emergency conditions as determined by the Superintendent of Public Works. In such circumstances, the DPW may require that the permanent patch be treated by a process (i.e. infra-red, microwave, or curb-to-curb) that will ensure that the patch is integrated into the existing bituminous surface in a seamless manner. The DPW will consider petitions to waive the five-year moratorium on a case-by-case basis.

Inspection of all water, sewer and drain construction must also be coordinated with the Department’s Utility Division.
