Stormwater Management

What is Stormwater?

Stormwater is water that originates from precipitation. Stormwater that does not soak into the soil or remain on the surface and evaporate becomes stormwater runoff.

Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lagoon, pond, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and recreation.

Polluted stormwater runoff can have many adverse effects on plants, fish, animals, and people.

The Town's strives to protect surrounding water bodies and enhance the natural resources by improving water quality through the promotion and implementation of effective stormwater management practices, regulation of land development, collaboration with regional jurisdictions, along with public education and outreach through its Stormwater Management Program.

Stay Prepared for a Storm

With the approach of Hurricane Idalia, it is crucial to remember to keep drainage system inlets clear. This will help to prevent flooding and property damage.

Why is this important?

Drainage system inlets are the grated openings in the ground and clear openings in curbs that allow water to flow into the storm sewer system. They can become blocked by leaves, pine straw, debris, and trash. Water cannot flow freely when this happens, and flooding can occur. Pipe ends in ditches can also become clogged.

Take Action: Keep Inlets Clear
  • Clear away leaves, pine straw, dirt, and debris from around inlets and pipe ends in roadside ditches.
  • Keep pine straw well away from inlets because it migrates quickly back to these inlets during heavy rainfalls.
  • Do not park cars or other vehicles over inlets.
Report Blockages

If you see a drainage system inlet or a pipe that is blocked, please report it using the MyHHI Mobile App or call the Stormwater Hotline at 843-671-7246.

By working as a community, we can help prevent flooding. Keep safe and let the stormwater flow.
