Project Description
The Downtown Mount Vernon Flood Protection and Revitalization Project will protect Mount Vernon's historic downtown from flooding with FEMA certified flood protection and serve to revitalize the historic downtown area. The project will remove the downtown from the FEMA 100-year base flood elevation and will release pent up economic opportunities that are so important to our region. The project is the key component of the comprehensive downtown redevelopment plan that is being used to guide public and private investments over the next 20 years.
The Project, which features a river promenade, trail system and public riverfront park, was done in three phases:
- Phase I: Completed October 2010
