2025 – FEMA Interior Sacramento Drainage Phases 1 thru 3

Hydraulic modeling and FEMA flood mapping was required for Levee Recertification. Project includes more than 10,000 acres and 10,000 drainage features in Sacramento including drainage basins 31, 34, 54, 91, 92, 95, 101, 103, 109, 140, 151, 152, 153, 157 & 158.

MRPE surveyed and modeled all stormwater storage and drainpipes, pumps, channels and roads that carry stormwater through these basins.

MRPE was selected as the most qualified firm to assist with one of the largest internal flood mapping efforts the city of Sacramento has undertaken in decades. Our proven system of providing more accurate and complete models was utilized for the majority of this work and will drastically improve the quality of flood information for a large swath of Sacramento.
