Pinellas County Municode Sec. 154-51
Drainage Requirements
(General) — A complete drainage system shall be provided for any development. All areas within a proposed development, including lots, streets and other areas, must be adequately drained. The drainage system will also account for any runoff from outside the development, if it passes over or through the development. The system will be designed both for long life and for low-cost maintenance.

  • Drainage of stormwater from property
    Stormwater Runoff is rainfall that does not seep into the ground, but runs off over yards, streets, parking lots and buildings. The stormwater runoff then enters our storm sewer system, which flows directly into creeks, lakes, Tampa Bay or the Gulf of Mexico.


Sec. 154 – Article III


Chapter 158 — Our floodplain management ordinances are designed to promote the public health, safety and general welfare, and to minimize public and private losses due to flooding.

Low-lying areas in Pinellas County that are adjacent to creeks, bayous, lakes, Clearwater Harbor, Boca Ciega Bay, Tampa Bay and the Anclote River are subject to flooding. Tropical storms and other threatening weather may also present flood hazards due to high tides, storm surges caused by winds and heavy rainfall.

This means that all of our residents are in a flood zone, with a risk designation of high, medium or low, so you should take steps to protect your property and financial security before disaster strikes. Most homeowners insurance does not cover flood damage. Talk to your insurance provider about your policy and consider if you need additional coverage.
