Prevention not Intervention Developing a Sound Response to Erosion and Sediment Control Problems through the Planning Process
The Stormwater Problem Changes in land use affects the hydrology of an area in four ways: 1. Change in peak flow characteristics 2. Change in runoff volumes 3. Change in water quality 4. Changes in hydrologic amenities
NonPoint Source Pollution • Agricultural runoff & leaching • Runoff from forestry activities • Construction site erosion & sediment • Urban stormwater runoff • On-site wastewater systems • Landfill leachates & Mining operations • Everyday human activities
Pollution from Stormwater Runoff • Generates almost all of the sediments found in Florida’s waters. • Contributes oxygen demanding substances in to water bodies at an amount greater than nine times that of a point sources • Flushes nutrients into water bodies at a rate comparable to the discharge from a wastewater treatment plant. • Deposits 80 to 95 percent of the heavy metals that reach Florida waters.
Causes of Noncompliance Inadequate implementation • Best Management Practices (BMPs) not installed correctly • Contributing areas changed, additional BMPs required • Poor Maintenance of BMPs • Inconsistent erosion control practices on sites • Unstabilized ground cover
Enforcement is time consuming and costly for regulators and the regulated community
We Found a Problem...Let’s Fix it! What direction do we go?
Nocatee at a glance Estimated 35,000 new residents to the county over the next 25 yrs.
BMPs to control erosion & sediment Proper implementation protects buffers & open waters Required with Stormwater & NPDES permits Costly tracking and enforcement of violations Complicated by multiple subcontractors & owners Lack of consistency in large developments Limited accountability in large projects Typical Stormwater Pollution Prevention Plans Negative Aspects Positive Aspects
