Hillsborough County Planners Propose Coastal Management Changes

Coastal High Hazard Area Plays Key Role in Proposed Changes

As part of its comprehensive plan update process, Hillsborough County has proposed a number of changes to the Coastal Management Section of the plan.  Much of the plan focuses on mitigating risks to people and property that lie within the County’s Coastal High Hazard Area (CHHA).  The CHHA is the portion of the county at risk of flooding from a a Category One hurricane and resulting storm surge.  The CHHA within in unincorporated Hillsborough County is designated in red in the map below. 

Some of the key changes in the plan impacting housing include:

  • New hospitals, nursing homes, and assisted living facilities will be prohibited in the CHHA;
  • New mobile home projects will be prohibited in the CHHA;
  • Use of stilted structures versus fill will be encouraged to meet flood elevation construction requirements;
  • Consider measures like transfer of development rights to incentivize development away from 25-year floodplain. 

The proposal also maintains several existing measures related to the CHHA, like requiring new development to demonstrate adequate shelter space or mitigate its impacts (i.e., contribute to costs related to shelter), and requiring use of planned unit development for various residential development. 

The County planning department is taking public comment on these changes through June 18.  After that, the changes will be considered at a Planning Commission hearing on July 12.  It is expected that the Hillsborough Board of County Commissioners will receive the planned changes and vote on adoption of them by October 2021.
