PW Northside Drive HROM City Project No. 106170

Project Description: The major work will consist of the (approximate) following:
The City of Fort Worth proposes to improve an existing storm drain system associated with
Northside Dr between Cold Springs Rd and Mercado Dr in Fort Worth, Tarrant County, Texas. A
pair of curb inlets from the roadway and a drop inlet from the Mercado Juarez restaurant parking
lot drain to a 24-in Reinforced Concrete Pipe (RCP) which crosses beneath Northside Dr. The
RCP outfall is approximately 150 ft south of Northside Dr and has created a severely incised
ditch, which drains into a tributary of the West Fork Trinity River. Erosion from the ditch is
migrating up-gradient and is undermining the existing outfall pipe. The proposed project would
involve the installation of a 48-in diameter RCP to replace the existing 24-in diameter RCP, reestablishment
of the outfall structure along the ditch, and the placement of riprap south of the
outfall to prevent future erosion.
The quantities and descriptions of the major items of work consists of the following:
1. Remove existing 727 SY concrete paving and replace with 11" concrete paving
2. Remove existing 316 LF, 24" RCP crossing and replace with 338 LF, 48" RCP crossing
