The City of Carmel requires that all land development activities
be designed to manage storm water runoff from developed areas
(including impervious surfaces and roof runoff) on the site of
its origin. All development shall be designed to minimize
pollutants that may result in water quality impacts. All systems
intended to connect with City stormwater systems, or proposing to
discharge stormwater to the public right-of-way require permits
and approvals from the Public Works Department.
