U.S. Army Corps of Engineers plan to protect Miami-Dade coast from flooding and storm surge ongoing Updated: Tags: MIAMI – The Army Corps of Engineers is working on a project to fortify the Miami-Dade County coast from sea level rise and storm surge. The project is in dispute, particularly their idea of a large concrete flood wall. At stake are billions of dollars, but local leaders are continuing to work to find a balance. “Elevating about 5800 structures and flooding proofing some 4600 non-residential commercial buildings,” explained U.S. Army Corps of Engineers Norfolk District Commander Col. Patrick Kinsman. One sticking point has been a proposed flood wall running parallel to Miami’s waterfront, a looming concrete structure that some local city and business leaders have argued would sink property values.
