Description: This feature class identifies locations where water courses and/or stormwater enter or exit stormwater assets. Attribution includes location data, the asset type, and the flow direction. Includes inspection forms for condition rating and maintenance activities.As of July 1, 2019, the Connecticut Department of Transportation (Department) is subject to the goals and requirements of a storm water discharge permit that aims to reduce the amount of pollution discharged to the state’s surface waters and wetlands.The "General Permit for the Discharge of Storm Water from Department of Transportation Separate Storm Sewer Systems” (General Permit) was issued by the Connecticut Department of Energy and Environmental Protection (CTDEEP) under the authority of National Pollutant Discharge Elimination System (NPDES) program.Within the NPDES program, the Department of Transportation is considered a non-traditional municipality. As such, the Department’s drainage system is commonly referred to as the DOT MS4, which stands for Department of Transportation Municipal Separate Storm Sewer System.The broad goals of the General Permit affect nearly every aspect of CTDOT’s operations, from design to construction to operations and maintenance. In order to address these goals, the Department has developed a Storm Water Management Plan (SWMP) that identifies best management practices for each goal. A copy of the SWMP will be available here on or before April 1, 2019.Beyond the initial development and implementation of the SWMP, the Department will also produce annual reports to detail progress in implementing each of the best management practices specified in the plan. Links to any annual reports completed to date and to other Department and non-point source pollution topics are included below.This data is digitized at a scale of approximately 1:500 and was digitized from the 2016 and 2019 CT imagery.The coordinate system used is NAD 1983 2011 State Plane Connecticut FIPS 0600 Ft US WKID: 6434 Authority: EPSG.It is edited in the Drainage Network - Office Editors group and is maintained by the Office of Environmental Planning in the Bureau of Planning and the Office of Environmental Compliance in the Bureau of Engineering.The data is updated daily. The metadata is updated as needed.
