J.F. Sato and Associates is the prime consultant for the design of a new bridge over Big Dry Creek at 144th and about 5000 feet of roadway improvements. JFSA performed the hydraulic studies to determine the opening and height of the bridge. A CLOMR is being prepared. Since the original FEMA and UDFCD models were not available in this reach, JFSA recreated these models using field survey data. JFSA also reviewed the hydrology on this basin to resolve a discrepancy between two earlier studies. We designed the storm sewer system and water quality features needed for this project. A new crossing was designed for the German Ditch, complete with a screened intake and bypass and improvements for ditch access and O&M personnel.
