“We ask the administration to lead the nation in rebuilding after Harvey and Irma by ensuring our communities and infrastructure are strong enough to withstand the next big flood, and would welcome the opportunity to work with the administration on such a standard,” states the coalition’s letter, which will be sent to the Trump administration on Monday morning.

President Trump revoked an Obama-era rule on this issue less than two weeks before Hurricane Harvey struck Texas, dumping some areas with more than 50 inches of rain. Some of the letter-signers had supported the axed rules, and sharply criticized their repeal.

Obama’s executive order, issued in 2015, said that development projects using federal dollars had to consider current and future flood risk, such as from rising seas. It offered three options on how to do this: building to where there is only a 0.2% chance of a flood occurring in any given year, building at least two feet above the ground, or using climate data to decide where and how high to build.
