6th Street Storm Drain Improvement
Aufbau prepared the structural plans for a 15’x7’ reinforced concrete box structure, the transition structure between a 96-inch diameter reinforced concrete pipe and the reinforced concrete box, a 22-ft wide side-drain connection to Cucamonga Creek Channel, and the associated containment walls. Aufbau also provided engineering support and construction management support services during the construction of the project.
6th Street master plan storm drain project consisted of construction of approximately 7,900 linear feet of mainline reinforced concrete pipes and reinforced concrete box structures, with laterals, catch basins, and appurtenances. The mainline introduced approximately 810 cubic feet per second of runoff at a new side-drain connection to Cucamonga Creek Channel. The storm drain mainline within 6th Street extended from Cucamonga Creek Channel to just west of Glenn Avenue and mainly consisted of reinforced concrete pipes ranging between 48-inch to 96-inch in diameter – for a total length of approximately 6,100 feet within 6th Street. The project also included construction of approximately 1,200 linear feet and 600 linear feet of storm drain mainlines within Vineyard Avenue and Baker Avenue, respectively.
The new connection to Cucamonga Creek entailed extensive hydrology and hydraulic studies and a 3D modeling of the Cucamonga Creek Channel towards the approvals of the U.S. Army Corps of Engineers and San Bernardino County Flood Control District. The new side drain introduced a 21-ft wide connection to Cucamonga Creek Channel.

Aufbau was instrumental in obtaining permits from the U.S. Army Corps of Engineers for construction of a 22-ft wide drainage connection to Cucamonga Creek Channel for City’s Sixth Street storm drain project. The permits required a comprehensive hydrology study of the drainage area tributary to the connection point and a thorough 3-D hydraulic modeling of an extensive reach of the Channel. Aufbau prepared the structural plans for the drainage connection and the transition structure to a 96-inch diameter reinforced concrete pipe. The plans were clear and concise and sailed through plan check at the U.S. Army Corps. Aufbau also provided engineering support and construction management support services during the course of construction, which were always timely and professional.Cindy Hackett, P.E. | Principal Civil Engineer
