Clear Creek Green Infrastructure Project

 This project helped to address combined sewer capacity issues in the Clear Creek West Combined Sewer Basin in the eastern portion of the City of Atlanta. The scope included the construction of a 4 million gallon combined sewer vault located at the Atlanta Civic Center; the construction of a 0.9 million gallon stormwater vault on the property of the Atlanta Housing Authority at Linden Avenue and Central Park Place; and approximately 0.9 million gallons of green infrastructure elements including a combination of bioretention and permeable pavers along city streets. The goal of the project was to improve reliability of the combined sewer system, reduce up to one million gallons of storm water runoff, enhance aesthetic appearance in neighborhoods, and reduce flooding potential. 

LONG established survey control in the project area using GPS and tied it to the City of Atlanta control system; provided topographic, utility and tree (identification, labeling and locating trees greater than 6” DBH) surveys for 5,500 feet of the full right of way of Myrtle Street, Willow Street, Nutting Avenue, Linden Avenue, Renaissance Parkway, and Pine Street; and 5,500 feet of half the right of way on Ponce de Leon Ave, Juniper Street, North Avenue, Central Park along Linden Avenue, Central Park along Central Park Place, and Pine Street; and a separate boundary and topographic survey of a 3.2 acre site on the corner of Central Park Place and North Avenue. Underground utilities were also designated, marked and surveyed for all of these areas utilizing electromagnetic and ground penetrating radar to ascertain the subsurface utility conditions present. GDOT SUE Quality Level B standards were adhered to for all subsurface utility investigations as a part of the project scope.
