The City of Tallahassee recently began construction on a project designed to alleviate ongoing residential and roadway flooding concerns in a southside neighborhood. Work began last month on the Emory Court / Dupont Drive Area Flood Relief Project, a $6,272,942 effort to provide significant flood relief to area property owners. The project, to be completed by June 2012, encompasses an area located west of Wahnish Way between Orange Avenue and Bragg Drive.

The project’s primary goal is to reduce flood levels along the East Branch Drainage Ditch between Wahnish Way and Bragg Drive. Relief from flood-related problems will be achieved through enhancements to the main ditch in the area, along with the construction of smaller storm sewers leading to the main ditch to alleviate flooding along Dupont Drive and Wahnish Court. This project includes the following structural elements:

Construction of an additional concrete pipe or culvert under Bragg Drive.
Lining over 1,500 feet of the ditch with rock filled wire baskets called gabions between the St. Marks pedestrian/bike trail and Wahnish Way.
Constructing 1,000 feet of steel sheet pile wall on the east side and nearly 1,500 feet on the west side of the ditch between Jake Gaither Golf Course and the pedestrian/bike trail adjacent to Glynwood Drive.
Additional erosion protection measures will be built on and around the existing pedestrian/bike trail bridge.
Drainage improvements along ditch connections from Dupont Drive and Wahnish Court.
Replacement of an aerial sanitary sewer crossing that spans the East Branch Drainage Ditch.

The project will provide significant flood relief to local residents by alleviating flooding dangers that have existed for some time. It will likewise improve public health, safety and welfare by eliminating roadway and residential flooding, stabilizing the ditch side slopes and enhancing protection along hazardous slopes located close to vehicular and public use areas. The project will also reduce erosion along the existing ditches, which in turn will provide storm water quality benefits in the area, including downstream wetlands such as Lakes Henrietta and Munson. Bragg Drive, temporarily closed to accommodate the construction, is scheduled to reopen the last week of April 2011.

This project is another example of the City’s long-standing commitment to improving critical infrastructure in historic southside neighborhoods. Along with the Emory Court / Dupont Drive project, other flood relief improvements completed in Tallahassee’s southside include the North Ridge / Fleetwood Flood Mitigation Project, the East Branch Stormwater Improvement Study, Pepper Drive Stormwater Improvements Project, Putnam Drive Stormwater Improvements Project, the Florida State University / City of Tallahassee Regional Stormwater Management Facility, the Southeast Sector Stormwater Management Study and the Tartary Drive Flood Relief Project. In addition, the City’s Neighborhood Enhancement Program provided numerous improvements for southside neighborhoods, including street reconstruction, sidewalks, curb and gutter and related drainage improvements.
