Prevention not Intervention

1. Prevention not Intervention Developing a Sound Response to Erosion and Sediment Control Problems through the Planning Process

2. 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

3. 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

4. The Construction Contribution

5. 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.

10. 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

11. Enforcement is time consuming and costly for regulators and the regulated community

12. We Found a Problem...Let’s Fix it! What direction do we go?

13. Nocatee DRI

14. Nocatee at a glance Estimated 35,000 new residents to the county over the next 25 yrs.

16. 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

17. Think outside the box Think outside the box! Typical SWPPP Think outside the box! Think outside the box! Think outside the box!

18. The Nocatee Story Goal: Find a way to protect water quality from construction activities by insuring implementation of erosion and sediment control activities on entire development. Process: Met with developer to find a way to protect resources within development construction related impacts

19. Solution Work for applicant to ensure compliance with development order conditions including meeting SWPPP requirements. Erosion Control Specialist

20. Master Developer Erosion Control Specialist Commercial Development Public Infrastructure Residential Development Owner/ Developer On-site Superintendent Mult. Sub-Contractors Laborers

21. Erosion Control SpecialistResponsibilities • Trained in erosion control implementation techniques • Set up and oversee programs to project buildout • Monitor onsite training and compliance • Meet with onsite superintendents • Quarterly updates and annual reports

22. Erosion Control SpecialistResponsibilities cont. • Attend pre-construction conferences • Conduct Homeowners Stormwater Training • Conduct Contractor Stormwater Training • Conduct periodic inspections of construction sites • Notify SJRWMD and FDEP of observed potential permit violations within 24 hours and serve as agency liaison

23. Desired Results • Create accountability • Uniformity • Reduce compliance efforts and costs • Provide liaison on site for agencies to work directly with

24. 25 year build out gives us plenty of time to... Evaluate Success of Program Quarterly Reports Annual Reports Department Sampling Efforts
