1:15-1:50 p.m. “An Overview of the San Diego County Coast” – Dr. Reinhard Flick
San Diego is one of the most liveable places on Earth. The main reasons for this are its climate and geological setting. The geography, physical coastal processes, including Pacific Ocean waves, tides and sea level fluctuations, as well as some substantial human modifications provide the forces that shaped San Diego's beautiful coastline. These are described and illustrated using dozens of photos, maps, and research materials and products assembled over many decades by the speaker and his colleagues and predecessors at Scripps Institution of Oceanography. The presentation emphasizes the crucial differences between the California coast and the nation's other coasts and highlights some implications for management policy and adaptation for future climate change effects. The introduction also provides an overview of the field trip to put the stops into context, and poetry by Robert Frost to put life by the Pacific into perspective.
1:50-2:10 p.m. “Shoreline Management and Sea Level Rise” – John Headland, Moffatt & Nichol
This paper presents methodologies for incorporating Sea Level Rise into the management of sandy shorelines. The basic methodology is to evaluate the amount of beach nourishment necessary to keep pace with projected sea level rise scenarios. Two approaches are considered: (1) the Bruun Rule and (2) a simple modeling approach that considers dune erosion and recovery on a decadal scale. The latter method, involves the following: 1. Input of beach profile, sediment characteristics, tide, and wave information 2. Analytical computation of dune erosion for a range of environmental conditions including, waves, storm tides, and sea level rise over a 100 year horizon 3. Empirical estimate of post-storm recovery 4. Weighted statistical estimate of dune recession for each decade 5. Integration of total dune recession over a 100 year period and 6. Comparison to the Bruun rule. East and west coast examples will be provided. The work tends to show that the Bruun rule is conservative relative to shoreline retreat. Both methods will be used to evaluate the overall scale of beach nourishment volumes and attendant costs needed to keep pace with sea level rise. An adaptive management approach to nourishment will also be presented.
2:10-2:30 p.m. “Managed Retreat – a Californian Adaptation Strategy” – Robert Battalio, ESA PWA
Managed retreat is a strategy to restore and maintain natural shores where coastal erosion and development clash. While there are many references to managed retreat and realignment as a shore management strategy, design guidelines do not exist. In particular, the design needs to address future conditions and the fear that effectiveness will be temporary. This presentation will summarize the design approach developed by the author while working on several managed retreat projects. The discussion will draw upon the following project examples: • Pacifica State Beach (constructed in 2005); • Surfers Point at Ventura River Mouth (Phase 1 constructed 2011); • Coyote Point Recreation Area in San Francisco Bay (Phase 1 construction scheduled for 2012); • Goleta Beach County Park (preliminary design completed 2011); and • Ocean Beach, San Francisco (conceptual design and master plan completed2012). The presentation will focus on the design process, with reference to design objectives and criteria, including sea level rise.
2:30 to 3:00 p.m. — Networking break
2:45 to 4:05 p.m. — Plenary session, Russ Boudreau, Susan Brodeur, & Shelby Tucker, moderators
3:00-3:20 p.m. “Beyond Counting Critters: The Ecological Economics of Beaches” – Philip King, Economics Department San Francisco State University
Over the past fifteen years, much progress has been made estimating the recreational benefits of beaches and developing specific tools. However, assessing the ecological services and functions of coastal management policies for beaches and other ecosystems is in its infancy. My talk will present an overview of the issues involved in assessing the ecological value of beaches and very preliminary results from a pilot study the ecological functions and services provided by open coast sandy beaches on the mainland coast of the Santa Barbara Channel. The study will concurrently examine and, if and where existing information is suitable, broadly estimate, the economic benefits and impacts of these ecological services. The project will also consider the ecological/economic impacts of selected coastal management policies on these ecological services. Such ecological services include but are not limited to: biodiversity, critical nesting and spawning habitat, water filtration, mineralization, promoting the health of nearshore and offshore ecosystems and carbon sinks, etc. The study will create an inventory of ecological services and functions at these beaches and assess methodologies for quantifying these services and functions in a meaningful way. In some cases economists have attempted to place dollar values on these services and some of these results will be briefly overviewed in this talk. In other contexts, policy makers have attempted to preserve critical ecosystem services or maintain critical natural capital.
3:20-3:40 p.m. “Impacts of the Severance Lawsuit on Texas Open Beaches” – Helen Young, Texas General Land Office
The Texas Supreme Court’s March 2012 decision in the Severance v. Patterson lawsuit raises many issues about the Texas Open Beaches Act and creates challenges to the 200-year tradition of public access to the Texas coast. The Texas Open Beaches Act, passed in 1959 and added to the Texas Constitution in 2009, was enacted to guarantee the public’s free and unrestricted access to the public beaches in Texas. The Texas Supreme Court’s recent decision found that a public easement does not exist on West Galveston, and public beach easements that do exist do not roll landward due to avulsive events like storms and hurricanes, as specified in the Texas Open Beaches Act. Numerous issues stemming from the Severance lawsuit involve the prohibition against using public funds on private property. One issue includes the government’s ability to conduct erosion and storm surge protection projects. When the Supreme Court’s opinion was initially issued in Nov. 2010, General Land Office Commissioner Jerry Patterson had to make the difficult decision to cancel a $40 million beach nourishment and dune restoration project for West Galveston that was desperately needed after Hurricane Ike caused severe beach erosion in 2008. The issue of using public funds on private property also impacts ongoing beach cleaning and maintenance by local governments and the General Land Office as well as post-hurricane debris removal, which the Legislature made the General Land Office’s responsibility following Hurricane Ike. In addition, the issue of public funds on private property could potentially prevent or reduce FEMA funding for repairing engineered beaches after major storm events. The General Land Office is rising to the challenges created by the Severance decision by working in close coordination with the City of Galveston, the Galveston Park Board of Trustees, property owners, and others to develop a workable strategy to help ensure public beach access in Texas while keeping the beaches clean, maintained, and sufficiently nourished to serve as the first line of defense against storm surges from hurricanes.
3:40-4:00 p.m. “The Water Institute of the Gulf” – Charles Groat, CEO, The Water Institute of the Gulf
Charles G. Groat, Ph.D. is the president and CEO of The Water Institute of the Gulf (TWIG). TWIG is the research arm of the Louisiana Coastal Protection and Restoration Authority (CPRA). The Institute will manage coastal research, house models and data bases that will be used for design and monitoring of coastal restoration and protection projects in Louisiana. The Institute will coordinate with Universities , consultants and scientists to update and run Master Plan Models to define the interrelationship of coastal projects on the health of the wetlands of Louisiana. They will provide a feedback to designers on project performance to enable adaptive management of sustainable coastal systems.
4:00-4:20 p.m. “The Great Tavarua, Fiji Swell of July 2011: A Tribute to Sean Collins” – Mark Willis, Surfline/Wavetrak, Inc
Surfline/Wavetrak, Inc was founded in 1985 by Sean Collins as a phone service that allowed callers to listen to surf reports for various areas in Southern California. The company has since grown into a global meteorological, oceanographic, and editorial company that specializes in producing surf reports, forecasts, and news for consumers, businesses, and government agencies worldwide. Surfline offers extended range wave and weather forecasts, high definition streaming web cams, custom surf and weather alerts, and a suite of other human and computer generated coastal observing and forecast products. Sean Collins, one of the most influential surfers and surf forecasters of all time, tragically passed away on December 26, 2011. This paper will attempt to honor Sean by analyzing one of the most significant and last swell events that Surfline’s founder was involved in: The Great Tavarua, Fiji Swell of July 11-13, 2011. Sean was deeply involved in all aspects of this swell. This included forecast consultations for multiple customers, on-site validation of human and computer generated forecasts, and producing incredible videography from Cloudbreak (a surf break about 2 miles offshore Tavarua Island). This swell was estimated to be 13-17 ft (4-5m) with periods of 15-18 seconds when it was just offshore Tavarua. The unique bathymetry of Cloudbreak allowed these swell heights to amplify some 2-3 times their height in deep water to produce surf heights up to approximately 50 feet (15m) on some of the largest set waves observed on July 12, 2011. The weather system that produced this swell consisted of a slow moving, very large area of low pressure system that was located south of New Zealand, the Tasman Sea, and Australia during July 6-9, 2011. This system interacted with a strong area of high pressure that was SW of Australia to produce a favorable fetch of 20kt (10 m/s) and higher SW winds that was up to 3000 nautical miles (5556km) long at times. Another key meteorological factor that led this extreme wave event was that the storm had multiple centers that rotated around each other. This allowed an area of 40-60 kt (18-31 m/s) SW winds and associated 35-50ft (11-15m) seas to propagate NE into the Tasman Sea during July 7-9, directly towards Tavarua Island. The dynamics of this extreme weather event, its relation to seasonal normals, and highlights of Sean Collins’ forecasts and video captured from this event will be presented.
4:20-4:40 p.m. Welcoming Members and ASBPA Update
4:40-5:00 p.m. “The Link Between Science and Policy” – Michael Walther, Coastal Tech
This presentation will summarize ASBPA’s congressional legislative priorities and Administration policies relative to the U.S. Army Corps of Engineers (Corps) and Water Resources Projects. In addition, the presentation will outline ASBPA’s legislative strategy including participation warranted by ASBPA members. ASBPA’s congressional legislative priorities include: • A 2013 Water Resources Development Act to provide for authorization of: o Corps Shore Protection, Environmental Restoration, Navigation and other projects that promote national economic development, health, and public safety - in the federal interest, o the Corps to implement true Regional Sediment Management studies and plans regardless of whether a federal navigation channel is involved, o the Corps to apply multiple continuing authorities in the implementation of a project. • Increased funding for coastal restoration projects and studies at an estimated federal cost of over $450 million for FY2013 and an overall Corps budget of at least $6 billion – including increased R&D funding for large- and/or small-scale field experiments to advance the field of coastal engineering. • Allowances for use contributed funds by the non-federal sponsor to fund projects and other creative funding mechanisms. • Authority for the Corps to prioritize its budget and projects based on economic development and scientific merits via the Corps Work Plan. • Authority for the Corps to assess and consider all national benefits – including recreation and environmental restoration - and costs for Corps shore protection projects. ASBPA’s federal Administration policy agenda includes: • Formulation of an efficient process to allow the Corps to study and Congress to authorize extending federal participation for already authorized critical shore protection projects that are reaching the end of their 50-year federal authorization. • Authority for the Corps to prioritize its budget and projects based on economic development and scientific merits via the Corps Work Plan. • Elimination of the “ban on new starts” to allow Federal funding for urgently needed Corps studies and projects currently barred under this ban.
