  1. Role of New Jersey’s Soil Conservation District Victor De Vasto Gloucester Soil Conservation District

  2. The Birth of Conservation Districts • Were formed in 1930’s by Federal legislation as a direct result of the Dust Bowl • In the 1937 New Jersey enacted legislation which established NJ’s Soil Conservation Districts • Today, there are over 3000 Conservation Districts in the US.

  3. New Jersey’s Soil Conservation Districts • Political Subdivision of the State of NJ • New Jersey Department of Agriculture

  4. Our Charge By NJ Legislature • “To provide for the conservation of soil & soil resources of the state, and for the control and prevention of soil erosion” • Providing technical assistance to farmers and landowners

  5. Implementation of our Charge • Soil Erosion & Sediment Control Act – Regulatory • Technical assistance to farmers & landowners - Voluntary • Innovative Programs • Regional Stormwater Management Planning • Low Impact Development • Tc Study for the Coastal Plain • Peak Rate Factor Study

  6. Soil Erosion & Sediment Control Act • In 1975 the State adopted the Chapter 251, P.L. 1975 • Chapter 251 was adopted due to the rapid development of the state and that soil erosion is accelerated by development. • SCD’s in NJ instantly became a regulatory agency

  7. Why a SESC Act in NJ • Annual Erosion Rate • Wooded Areas • 0.2 Tons/Acre/Year • Developed urban areas & grassed pastures • 1.0 Ton/Acre/Year • Active Construction Sites • 50.0 Tons/Acre/Year

  8. SESC GOALS • Reduce danger from stormwater runoff • Retard NPS from sediment • Conserve & Protect our Natural Resources

  9. SESC Requirements • Prior to any disturbance, a developer must submit SESC plans to the SCD for review & approval. • Plans are designed by a NJ licensed Engineer • Plans are prepared using Structural, Non-Structural & Vegetative SESC Standards adopted by the State. • Plans denote how soil is to be retained on site & minimize off site erosion during construction

  10. Projects Requiring a Plan • Any Soil Disturbance over 5,000 sq. ft. • Demolition • Parking Lots • Public Facilities • Quarrying/Mining • Clearing/Grading • Industrial, Commercial & Residential

  11. Plan Development • Must be prepared by a licensed NJ Engineer or Architect • An NJ licensed Engineer must prepare the plans if: • Storm drainage facilities are proposed • Site contains 10 acres or more • Slopes of 5 degrees or more • Site is traversed by a water course

  12. Soil Erosion & Sediment Control Standards • Plans must be designed using the SESC Standards • Vegetative • Engineering • Runoff Treatment

  13. Inlet Protection

  14. Sheet Flow does cause erosion!

  15. Detention Basin

  16. Wet Detention Basin

  17. Infiltration Basin w/Sand Bottom

  18. Detention Basin with no Low Flow Channel

  19. COP with Concrete

  20. COP with Rip Rap

  21. Plan Submission • 3 copies of the SESC plan • Drainage Report • Stability & Erosion Control calculations • Site Plan • Stream Encroachment Plan & Report

  22. Plan Review • Required by law to review plans within 30 days • Applicant & design engineer is notified in writing of any deficiencies • Engineer submits revised plans to the district and the 30 day clock begins again • Less than 1% of the plans received are certified in the first review. • Usual approval time takes approx. 3-6 months

  23. Pitfalls to Avoid • Double check plans & calcs before submission • Cooperate with SCD • Submit all information • Design your plan – don’t wait for our comments • Don’t over design • Set-up a pre-application meeting • Heed SCD advise & suggestions • Develop a relationship with regulatory agencies – clients come and go!

  24. Site Inspections • Projects are inspected frequently during construction to assure compliance with the plans • Reports of Compliance must be obtained for CO • Work with developer to achieve compliance • Enforcement

  25. Tips During Construction • Clean streets – weekly street sweeping • Install & MAINTAIN SESC measures on plan • Internal inspections • Vegetate exposed areas • Storm system free of sediment

  26. Enforcement • Withhold Reports of Compliance • Stop Construction Order • Legal Action - $3,000 per day per violation

  27. Interaction with Groups & Agencies • Design Engineers – SESC Act • Contractors & Developers – SESC Act • South Jersey Builders League – SESC Act • Municipalities – SESC Act • NJ DEP – NPDES Permit, Grants, Stream Encroachment, Watershed Management • Gloucester County

  28. A Final Thought • The cost of corrective action or remediation is about 30 to 50 times greater than installing the erosion control measures and following the certified plan.
