News - Forest Hills Drive Drainage Improvements – Fayetteville, NC
October 15, 2012 – For many years, the City of Fayetteville has experienced flooding at four street crossings from Spruce Drive downstream to Forest Hills Drive over an un-named tributary to Little Cross Creek. Having performed the initial analysis of the system as a whole, JEWELL Engineering determined that the downstream-most crossing, Forest Hills Drive, should be upgraded first in the series.
JEWELL was contracted by the City to perform detailed analysis and design and to prepare construction drawings and specifications for a replacement culvert system at Forest Hills Drive. The existing culvert system consists of three 36-inch RCPs under Forest Hills Drive that transition to a single 64-inch by 52-inch CMPA which carries flow from the street about 200 feet through a vacant lot to a discharge point at a natural channel leading to Little Cross Creek. Numerous utilities are present at the site including sanitary sewers lines, water lines, power, and others. A 21-inch sanitary outfall crosses the site at the downstream discharge point.
JEWELL designed a double barrel 12’ wide by 3’ high pre-cast concrete box culvert system with precast endwalls to carry the crossing at Forest Hills Drive. A natural open channel discharging to Little Cross Creek will replace the CMPA downstream of the street. A riprap/gabion lined stilling basin was designed to transition flow from the box culvert barrels into the new channel. JEWELL designed a number of utility relocations to accommodate the new culvert and channel. Documentation to obtain State and Federal erosion and sediment control, water quality, and wetland permits was prepared and successfully processed. The project was put out to bid in October 2012 and construction is anticipated in the fall and winter of 2012-2013.
