ACI has provided engineering design services for multiple agencies in Southern California since 1993.
We have provided floodplain analysis, bridge hydraulics and scour studies, and sediment transport analysis for several major bridges over waterways and rivers.
We have prepared hydrology and drainage studies and preliminary and final drainage plans in support of numerous roadway and bike trail improvements.
We have prepared multiple Water Quality Assesment Reports (WQAR), Water Quality Management Reports (WQMP), Stormwater Pollution Prevention Plans (SWPPP), Location Hydraulics Studies (LHS), and Summary Floodplain Encroachment Reports (SFER) in support of major roadways, trails, and drainage improvements.
