The Town of Islip is a coastal community with a great deal of interest in managing our floodplain and providing support to the residents potentially affected by a storm event in our area. The Town's Code provides the foundation for the defense of our coastal communities and sets the parameters for the health and resilience of the Town. You can view the Town Code at: for a more detailed understanding of floodplain management.

The primary objective of these floodplain ordinances is to protect human life, as well as:
  1. Minimize the expenditure of public funds for costly flood control projects.
  2. Minimize the need for rescue and relief efforts.
  3. Minimize prolonged business interruptions.
  4. Minimize the damage to public facilities and utilities.

The below is provided as a gateway to keep residents informed and updated on the latest information regarding the floodplain, flood insurance, as well as how to best prepare for flooding events.
