First Creek Channel Improvements
CLIENT: City of Knoxville, TN
The City of Knoxville was faced with a dilemma. For years, major flooding problems plagued the homes and businesses along a 1.6-mile section of First Creek from Chickamauga Avenue at North Broadway to Broadway north of Mineral Springs Avenue. After every significant rainfall, the First Creek channel would crest and flood homes, businesses, and roadways in the surrounding area.
The City of Knoxville, seeing these issues, made the drainage project part of their long- running effort to reduce flooding in this section of North Knoxville. Vaughn & Melton set about developing design plans in 1999 to help alleviate the flooding. The project included ten bridges, a channel bench, and extensive sanitary sewer relocation. By 2000, preliminary plans had been completed for all bridge replacements and channel construction for this reach of the creek.
In 2009, construction plans were completed and work began on the First Creek channel from Chickamauga Avenue at Broadway to Emoriland Boulevard. The scope of work included widening a 1,853-foot long section of First Creek to provide an additional 40-foot wide, grass-lined, high-flow channel adjacent to the creek. The plans also called for replacing the existing bridge at Fairmont Boulevard and constructing 450 LF of retaining wall. A new bridge at Emoriland Boulevard was also designed to provide for the 300-foot section of the high-flow bench that deviated from the creek.
