Other department functions include addressing resident concerns related to stormwater management, drainage and sidewalks. The office is also responsible for the assignment of street addresses.

Excavation Permits

Any construction work that occurs within a city highway right of way is regulated by ordinance and requires an excavation permit. The city right of way extends beyond the limits of the roadway pavement and includes the shoulder area and any public sidewalk. The staff inspects all permitted excavations to ensure their proper restoration with a temporary pavement repair. The scheduling and oversight of permanent pavement repairs is the final phase of the permitting process. Excavation Permits are required for the following activities:

  • Installation or replacement of utility mains and building services
  • Installation, replacement or repair of sanitary sewer building connections (including on
  • private property)
