3. BUILDING STRONG ® The Encinitas and Solana Beach Coastal Storm Damage Reduction Project is a 50-year effort to: 3 Project Purpose  Reduce coastal storm damages to property and infrastructure along the study area shoreline and the bluff top, prior to the need for emergency action.  Improve public safety in the study area by reducing the threat of life- threatening bluff failures caused by wave action against the bluff toe.  Reduce coastal erosion and shoreline narrowing to improve recreational opportunities for shoreline users within the study area.

Reduced beach access and recreational opportunities Increased armoring and bluff failures Beach areas return to cobble Coast Highway 101 and Cardiff State Park jeopardized due to coastal inundation Future emergency measures/actions will be required to protect public infrastructure No Project Alternative 15

16. Pre-RBSP 1 (1998)Post-RBSP 2 (2013) 16 10-29-13 Since 2001, over 1 million cubic yards have been added to the intertidal zone off Encinitas and Solana Beach. Restored habitat for grunions, shorebirds, sand crabs which was non-existent prior to the regional beach sand projects. Re-created some surf-breaks and improved surfing. Surfer Magazine rated Encinitas as #3 Best Surf Town in America in 2009. Successful Sand Replenishment Projects

Beach nourishment allowed within Swami’s SMCA. EIR/EIS Technical Review determined no potential for significant impacts to biological resources in SMCA. Extensive monitoring will be conducted for surfing and biological resources following implementation. 18

23. Project will protect: 23 Public Infrastructure Public Access Staircases Lifeguard Towers Public Streets Public Parks and Community Centers Reduce emergency actions Increase safety of beach users

24. Public Access & Safety Benefits Protects public beach and coastal access Creates new public beach areas (+ 35 acres) Increased public safety at the public beaches 24

25. Project Revisions Since July 2013 hearing we have: Reduced the beach widths and sand volumes in both Cities: Encinitas beach width reduced from 100’ to 50’ Solana Beach width of beach reduced from 200’ to 150, Increased the biological, cultural, lagoon and surf monitoring requirements. 25

26. Coastal Commission Sea Level Rise Guidance Document Beach nourishment is the preferred adaptation strategy for sea level rise : “ “ Maximize natural shoreline values and processes and embrace green infrastructure and living shorelines; avoid the perpetuation of shoreline armoring.” “Require “soft” or “living” shorelines such as beach nourishment as an alternative to shoreline protection devices.” “Establish a beach nourishment program and protocols” Proposed beach nourishment project designed to be resilient to sea level rise over 50 year life – EIR/EIS evaluated various sea level rise scenarios. 26

27. Project Provides Economic Benefits Beaches are important low and no-cost destinations for California residents and visitors. California’s beaches contribute $73 billion to the national economy and generate $14 billion in tax revenues for the federal government. California receives less than one tenth as much in Federal appropriations as New York and New Jersey, states which have fewer miles of beaches. 27 Source: The Fiscal Impact of Beaches, by Philip King, Ph.D. Prepared for the California Department of Boating and Waterways (1999 )

28. This Project is critical to our Cities  No dry public beach - even at low tide.  Project will restore the public beach, coastal access and provides no and low cost visitor serving recreation.  A sandy beach reduces wave action against the bluffs.  The Project is consistent with CCC sea level rise guidance.  Project incorporates extensive monitoring.  Mitigation will be provided if there are significant impacts.  Best long-term opportunity to provide sand and reduce the need for armoring and reduce the loss of public access.  Beach sand is temporary and moves with daily tides, currents, and swells. Project re-nourishment actions can be modified/reduced based on actual conditions.  Seawalls and loss of beach access are permanent if there is no beach.  Your support is needed. 28
