GIS Stormwater Mapping Planned Through June 2017

October 10, 2016

Geographical Information System (GIS) storm sewer mapping will continue within the City of Oak Ridge through June of 2017. This project may require crews to access private residential properties for mapping and assessment purposes.

The Stormwater Management Team is currently working to finish mapping the southern tributaries of the East Fork Poplar Creek from Tuskegee Drive to Gum Hollow Road. The expected completion time is November of 2016. After completion, the team will begin mapping the watersheds southwest of Melton Lake. This section includes all areas between Melton Lake Drive, Edgemoor Road/Old Edgemoor Road, Union Valley Road, and Highway 62.

By monitoring certain streams and tributaries, the City is following guidelines set forth by the U.S. Environmental Protection Agency (EPA) and the Tennessee Department of Environment and Conservation (TDEC) under the Phase II Municipal Separate Storm Sewer System (MS4) permit. The goal is to protect and rehabilitate our natural water resources. To help achieve this goal, the City created a Geographical Information System (GIS) storm sewer map and database program to identify stormwater outfall locations of the U.S. Waters of the State.

In order to facilitate the program, City representatives may need to access residential property during reasonable hours to identify stormwater outfalls along streams. This is not a request to enter any building or structures on the property; it is specifically for the purpose of identifying outfalls along streams (or their tributary watercourses). No construction will be taking place. Representatives of the City will be mapping these outfalls with GPS units and/or making visual assessments of the watercourse.

The City thanks you for your cooperation in complying with this State and Federal mandate, and assisting in making our water resources cleaner for everyone. Please note, all mapping locations are subject to change due to weather or unforeseen circumstances.
