Walton County, FL Environmental Rules: Erosion Control (2026)

The Coastal Dune Lake Protection Zone (CDLPZ) extends 300 feet landward from the mean or ordinary high water line of the county's coastal dune lakes and their tributaries. B is the specific erosion-control mandate within that zone: builders must use "staked and staggered hay bales, siltation barriers, floating silt and filter berms" during construction, and those measures must stay in place until the disturbed soil is stabilized by permanent vegetation that stops sediment from leaving the site. The same section pairs erosion control with a certified Low Impact Development stormwater plan (Subsection A), a ban on new septic systems where central sewer is available (Subsection E), a requirement that at least 60 percent of the 300-foot zone stay pervious open space (Subsection F), and a mandatory county land-clearing permit before any clearing occurs within the CDLPZ (Subsection I).

03 carries an unusual supermajority lock: it "shall not be amended or repealed unless by an affirmative vote of at least four (4) members of the Board of County Commissioners," a higher bar than an ordinary ordinance change. c for the separate Shoreline Protection Zone around rivers, creeks and Choctawhatchee Bay, so a project touching both a dune lake and a bay shoreline must satisfy each zone's own clause.
