Implementation

Construction Site Stormwater Runoff Control

 



Purpose

Construction sites can be substantial sources of pollution to our waterways if stormwater management controls aren't in place. This section of the permit outlines minimum standards for preventing stormwater runoff from construction activities that disturb one or more acres of land.

Relevant terms

Development: means any construction or grading activities to improved or unimproved real estate.

Disturbed area: means an area where the ground cover is destroyed or removed leaving the land subject to accelerated erosion.

Resources

Statewide construction site guidance

Under this control measure, towns should require developers, construction site operators and contractors to be consistent with the practices and standards in Connecticut's 2002 Guidelines for Soil Erosion and Sedimentation Control and Stormwater Quality Manual.


DEEP Construction General Permit

Communities are required to notify developers that they may have to meet additional stormwater requirements under the CT DEEP Construction General Permit. The construction general permit applies to projects disturbing more than than 5 acres.


Legal Authority

Construction site stormwater runoff control legal authority examples should be available by late Summer 2018.

Template Stormwater maintenance declaration from the Greenwich Stromwater Drainage Manual.
