Field surveying, modeling, public involvement, easement mapping, and final construction drawings for storm water improvements to a tributary of Campbell Creek. The project area consisted of 10,000 linear feet of stream channel and two adjoining closed piped systems. Construction drawings and all field surveys were performed by Armstrong Glen.
The purpose of the project was to repair channel erosion, minimize structure flooding, and to eliminate roadway overtopping in a 227-acre (0.335 sq. mi.) drainage area. Hydrologic and hydraulic models were created using the Corp of Engineers HEC-1 Flood Hydrograph Package, Corp of Engineers HEC-RAS hydraulic analysis program, and XP-SWMM. Construction cost $1,370,000. Project duration was March 1998 to February 2003.
