ERP Elements What’s in One of These Things? E1 - A building setback line E2 - A prohibition on new construction seaward of the building set-back line. E3 - Narrow exemptions from the construction prohibition E4 - Stricter construction standards for exempt properties E5 - Procedures for preserve & enhancing public access E6 - Procedures for preserving, restoring, and enhancing critical sand dunes E7 - Criteria for voluntary acquisition of property seaward of the building setback line Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Building Setback Line Why Create an SBL? Protect future development from Catastrophic Risk of Shoreline Erosion Reduce Public And Private Costs of Post-storm Recovery Limit Property Damage And Loss of Life Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

North Carolina Outer Banks: This is what happens when you don’t anticipate shoreline change Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Impact of Erosion on SPI Lot Position # of Lots Tax Assessed Value Submerged Lots 61 $280,839 Partially Submerged 106 $35.2M On the Beach 92 $2.4M

Building Setback Line County Shoreline is Not Uniform Zone 1 – Boca Chica Site of Space X Launch site Limited future development pressure Areas of accretion, limited erosion areas Zone 2 – Northern SPI City Limit to End of PR 100 Most Likely to develop - Road & Utilities in place Erosion rates at 10 to 12 feet per year Zone 3 – End of Road to County line Unlikely Near-term development – No road or utilities Erosion rates 15 to 20 feet per year Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Zones 2 & 3 – Not Uniform Wide Almost Dune-less Stretches

ZONE 3 – Shear Scarp of Eroding Primary Dunes (About Mile Marker 14)

Building Set-Back Line Calculating a Setback ZONE 2: Northern City Limit to End of PR 100 Planning period: 30 Years Average Annual Erosion Rate: 10 to 12 feet/year Setback Baseline: Mean High Tide Line (MHT) Setback Calculation: Erosion rate x Planning Period Example: 30 years x 11 ft/year = 330 foot SBL Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Building Set-Back Line Addressing Uncertainties Setback Baseline Issues (MHT, MLT, LOV) All the SBL Baselines Fluctuate Fluctuation Creates Uncertainty in SBL Addressing SBL Uncertainty in the ERP Avoid Permit-by-Permit SBL Determinations Seek Consistency and Equity in SBL Create SBL “Lifespan” Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Building Set-Back Line Two Cornerstones for Success Relocate PR 100 The SBL Moves Development Landward PR 100 location impinges on developable space Relocation of PR 100 is recommended Develop & Implement a Shoreline Response Plan Implement Beach Nourishment & Sand Management/Retention Strategies to reduce erosion rate Establish consistent, wide, healthy dunes seaward of development Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

E1 The Shores Setback Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Construction Prohibited Seaward of the Building Setback Line The ERP will prohibit construction of all habitable structures seaward of the Setback Line Exemptions for Allowed Structures Seaward of Setback Line -- Walkovers and Similar Amenities Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Exemptions & Stricter Construction Standards for Exempt Properties No Exemptions Are Included so No Stricter Building Standards are Necessary Because no Habitable Structures will be Seaward of SBL, Stricter Construction Standards would not be developed seaward of the Setback Line Improved construction standards may apply to walkovers and related amenities Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Procedures for Preserve & Enhancing Public Access Zone 1 - Boca Chica No Change (Vehicle access) Zone 2 – SPI City Limit to The End of PR 100 Transition to a Pedestrian Beach Requires Significant New Off-Beach Parking Zone 3 – PR 100 end to County Line No change (Vehicle access) Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Preserve & Enhancing Public Access ERP Element #5 Preserve & Enhancing Public Access Acquire New Access Ways Spaced ½ to ¾ mile 88 – 100 Off-Beach Parking Spaces per access Create seaward dune & add walkovers Phased Implementation- convert to pedestrian beach as access are acquired and improved Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Preserving, Restoring & Enhancing Critical Sand Dunes Wide Healthy Dunes Seaward of the Setback Line are Critical and a Foundation of the ERP Existing Dunes Seaward of the Setback line will be Preserved and Enhanced Existing Dunes Landward of Setback Line will be relocated seaward In areas where Dunes are absent or Fragmented, Dune Restoration will be undertaken Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Preserving, Restoring & Enhancing Critical Sand Dunes ERP Will Specify Basic Dune Plan and Specifications Dune height: At least 75% of Base Flood Elevation (BFE) Dune Width: Varies between 100 to 250 feet Dune Volume per Foot: ******** 50 to 80 cubic yards Dune Plants: Native vegetation, 6 to 12 inches on center Irrigation: Yes, if possible, with grey water reclamation Dune Permitting: Master Plan Permit or Permit by Rule Coordinated and phased implementation through County Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Criteria for Voluntary Acquisition of Property Seaward of the Building Setback Line Establish Acquisition Criteria Acquisition By: Donation Purchase Transfer of Development Rights Funding Options NFWF (Federal grant funds) Restore Act FEMA HMGP Local Special District Taxes (PID) Other TBD Text Questions to (512) 968-6816 Project website: cameroncountyerp.com

Expected Outcome A Plan to Stabilize or Counter High Erosion Rates Beach Nourishment Sand Retention Strategies Wide, Healthy Dunes to Protect Future Development Vehicle Access Limitations? Off-Beach Parking @ about ½ to ¾ Mile increments 88 parking spaces per access point Access Possible Streamlined Permitting Landward of Setback Line
