Houston a year after Harvey: Where we are and where we need to be

This paper provides background information on critical flooding problems in the Houston and Harris County areas as a result of Hurricane Harvey, presents an update on progress made to date, discusses successes and shortcomings of existing flood mitigation plans, and shares some ideas about moving forward with plans for the future.

First, the issues of obsolete 100-year floodplain maps and increasing rainfall are discussed because they are key to fully understanding the current dilemma and shaping alternative concepts for long-term protection. Second, a geographic overview of the flood issues and potential responses to various watersheds across Harris County are set out. Third, different flood management concepts are discussed for three zones of the Houston area that have different flooding issues.
