TESC Manual

Temporary Erosion and Sediment Control Manual

The GESC/DESC Manual has been renamed the Temporary Erosion and Sediment Control Manual (TESC Manual) and has been revised to comply with the Town's MS4 (Municipal Separate Storm Sewer System) Permit with the Colorado Department of Public Health and Environment. For projects permitted prior to July 1, 2019, the GESC Manual is in effect.

The TESC Manual describes the permitting program that has been adopted to promote environmentally sound construction practices in Town. The goal of the program is to implement erosion and sediment control measures as a standard for all land-disturbance activities. The hope is to reduce increases in erosion and sedimentation over pre-development conditions. Erosion caused by construction and downstream sedimentation can damage property and degrade the quality of streams and lakes. The TESC Manual is a large document, so it may take several minutes to open the full manual.
