13. The importance of recognizing these features lies in the fact the same areas tend to be washed over during subsequent storms Is there a way to incorporate this vulnerability into Dune Restoration Strategy or Not???

14. Shoreline Position and Dune Management Strategy

15. a nice wide high tide beach backed by a gently sloping and well vegetated sand dune. Natural dune dynamics - storm cut and recovery

16. waves lower the beach and erode the dune behind Sand eroded from both the beach and the dune is transported offshore and deposited as a bar. The lowering of the beach and the deposition of sand offshore creates a wide shallow platform - which helps dissipate the increased wave energy which occurs during storms.

19. Over a period of weeks (and sometimes months) after the storm, more gentle waves gradually return the eroded sand from offshore back to the beach. This restores a high tide beach. If the dune has sand trapping vegetation then it begins to extend down the dune face. The steep dune face will also gradually collapse to a more gentle angle.

20. Native sand trapping vegetation grows down the seaward dune face, it slows the wind close to the ground. This reduces the amount of sand the wind can carry – so large volumes of sand carried in the wind drop out and are trapped by the plants. This natural sand trapping process gradually builds and repairs the dune.

22. Presentation Overview We’re Here to Listen to You What is an Erosion Response Plan? Why Prepare an ERP Purpose of the ERP Schedule for ERP Consideration How to Participate in the Process Elements of an ERP ERP Challenges Open Discussion Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

23. What is an ERP? An Erosion Response Plan is a State-Mandated Plan that must be Adopted by Coastal Cities and Counties under 33 TNRC § 33.607 The Legislature concluded that the public will benefit from ERP adoption because of reduced public expenditures associated with loss of structures and public infrastructure due to storm damage and erosion, disaster response costs, and loss of life. Local governments that fail to adopt an ERP are ineligible for state financial assistance and grants under CEPRA (Erosion Project Funding) Program Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

24. Why Adopt an ERP? The Plan is Legally Mandated Ensures Access to State Coastal Grants and Financial Assistance under CEPRA Development on Barrier Islands can be Risky Given Periodic Hurricanes & Tropical Storms Post-Storm Recovery Costs can be Substantial Public: Federal, State & Local Costs Private: Costs to Private Property Owners & Insurers Improved Planning Can Reduce Losses Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

27. ERP Process Local Action Prepares ERP with Public Input Based on Shoreline Data provided by UT-BEG Local Government Adopts the ERP State Review and Approval of ERP “The ERP must be submitted to the General Land Office for review and approval as a dune protection and beach access plan amendment “A local government's governing body must formally approve the ERP prior to submission to the General Land Office.” Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Beneficial use of dredged material is limited Can we find and afford a long-term sand supply Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

39. ERP Challenges 2 Do we have the funds to manage the shoreline? ERP must include implementation funding plan Limited State Funds (CEPRA) Unlikely Federal Investment (No new federal projects) How do we Raise and Sustain Local Funds? Special Tax Districts or Assessments? County-Wide Funds? How should costs be allocated? Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

40. These are the Challenges of Developing the County’s Gulf Beaches Can we find a way to address the risks or erosion?
