Hartford FAQ
Do I need a stormwater plan for my project?
Generally required for new construction and major renovations that increase impervious surface area. Small residential projects may be exempt.

Any non-stormwater substance entering the storm drain system, including paint, oil, chemicals, or sediment. Report violations to Hartford public works.
New Britain FAQ

Projects disturbing less than one acre typically do not need the state Construction General Permit, but local erosion control approval is still required and best management practices apply under municipal ordinances.
Can towns adopt weaker stormwater rules than the state?
No. Connecticut municipalities must implement at least the minimum control measures required by the MS4 general permit. Local rules may be stricter but never less protective than state standards.
