Services in Bristol

Working with local offices

A lot of site work in town touches local approvals. Here's who usually handles what:

  • Septic systems: the Bristol-Burlington Health District, which serves both towns, handles soil testing, plan review and inspections for subsurface sewage systems.
  • Wetlands: clearing, grading or building near wetlands and watercourses goes through the city's inland wetlands commission.
  • Building and zoning: foundations, additions and new homes go through the building and zoning offices.

We'll tell you which ones apply to your project before we start. For the septic process in detail, see How a new septic system gets approved in Connecticut.
