Our verification notes
Category caveat: this is a 900-person employee-owned multidisciplinary firm, not a barrier manufacturer or installer, so it qualifies on the design leg only. Its flagship Minnesota flood credential is a municipal riverfront floodwall dating to 1998-2001, which is infrastructure rather than a building envelope. Its Google rating rests on four reviews. A later research pass added the named PE, PH and CFM above and the firm's Minnesota floodplain association award, which is why this entry is tier 1. One currency warning: an engineer who co-presented SEH's Minnesota River crossing flood study in 2022 has since moved to the state transportation department and is not current staff.
