10GENERAL Description Brief 2-3 sentence description of the purpose of the tool. Searchable web tool providing 1) maps users can customize, embed, & download; 2) downloads: spreadsheets, slideshow-ready tables & graphs, & fact sheets; 3) individual community analyses; 4) area comparisons; 5) local sea level & flood risk projections. 100+ demographic, economic & infrastructure variables analyzed for 1000s of communities from zip code to statewide levels. Tool allows users to visualize community-level impacts from coastal flooding or sea level rise and provides easy access to inundation and elevation data via NOAA's Digital Coast. An online mapping tool customized for local and state decision makers showing potential impacts from sea level rise and coastal hazards designed to help communities develop and implement solutions that incorporate ecosystem-based adaptation approaches Provides access to sea-level rise scenarios generated by the Pacific Institute, ESA PWA and the U.S. Geological Survey as part of the CA Energy Commission's Public Interest Energy Research Program (PIER). The tool shows the threat of coastal erosion and inundation due to flooding over three depths based on a 100 year flood scenario. Currently (spring 2016) provides access to two different sea-level rise flooding models. The first is based on the CoSMoS model developed by USGS to represent sea level rise and storm events, accounting for physical structures, wave dynamics, coastal erosion, and other hydrodynamical factors. These data are available for the Bay Area and outer coast from Bodega Head to just south of Pillar Point Harbor in Half Moon Bay. The second ("bathtub") model represents the open coast as well as Bay Area based on scenarios generated by the Pacific Institute, ESA PWA and the U.S. Geological Survey as part of the Energy Commission's Public Interest Energy Research Program (PIER). ... The tool shows the threat of inundation due to flooding over three depths based on a 100 year flood scenario. NOTE: Cal-Adapt is currently (summer 2016) being migrated to "Cal-Adapt 2.0", which is based on an Applications Programming Interface (API) that enables development of third-party tools. Cal-Adapt 2.0 will also display (summer/fall 2016) 1- results from high-resolution hydrodynamic modeling of extreme storm events + various increments of sea level rise (up to 1.4 m) for the Sacramento-San Joaquin Delta, Bay Area, and open coast; 2- results from an ongoing research project funded by the Energy Commission to produce a probabilistic interpretation of the wide range of plausible sea level rise for California. A collaborative, user-driven project focused on providing San Francisco Bay Area coastal resource and land use managers and planners locally relevant, online maps and tools to help understand, visualize, and anticipate vulnerabilities to sea level rise and storms.

10GENERAL Top Three Strengths As succinctly as possible, list the top three strengths that make this tool unique. 1) Comprehensive tool providing exposure analysis, comparisons, and projections, as well as an interactive map. 2) Analyses cover ~100 variables, and conducted for 1000's of individual areas (zips, cities, counties, states, planning and legislative districts at all levels). 3) Local projections combine sea level rise and storm surge to give integrated risk estimates by decade. 1) Easy to use via Web browser, with GIS analysis results and map services available; 2) Uses consistent data sets and analysis for coastal areas nation-wide; 3) Includes photos and allows users to customize local scenarios and visualize impacts of sea level rise at known locations. 1) DESIGN: The tool has a modular, plugin architecture: Coastal Resilience “apps” can be developed by anyone and plugged into the web-based mapping platform. This allows developers to design a specific application to highlight a coastal management issue, respond to a disaster for post-storm decision making, or emphasize nature-based alternatives; 2) PERFORMANCE: Coastal Resilience 2.0 runs faster; ... operates on tablets; works nationally and globally; is open source, and it’s easy to share results and data; 3) PARTNERSHIPS: Developed among core partners including The Nature Conservancy, University of Southern Mississippi, The Natural Capital Project, NOAA Coastal Services Center, and the Association of State Floodplain Managers 1) First comprehensive analysis of the impacts of sea level rise across the state of California. 2) Considered impacts from several depths of inundation, coastal storms and erosion. 3) Used FEMA's HAZUS model to estimate level of economic risk from inundation 1- Continually updated. 2- Forthcoming enhancements will include detailed representation of potential impacts (with regard to levee overtopping) of sea level rise plus extreme storm events in the Sacramento-San Joaquin Delta as well as the Bay area and open coast, based on three-dimensional hydrodynamic modeling. 3- Forthcoming enhancements will include probabilistic sea level rise projections to help decision-makers contend with a wide range of plausible SLR values for California. 1) The model underlying the tool, CoSMoS, applies a deterministic modeling framework to cover large geographic scales but with fine local resolution. The system incorporates atmospheric forcing (i.e., wind and pressure fields) from Global Climate Models and accounts for all the relevant physical processes that will contribute to the vulnerability of the coast now and in the future (e.g., SLR, tide, waves, surge, fluvial discharge, storm variability) and the resulting coastal hazards. ... 2) One of the primary objectives of this project is to understand regional coastal flood planning information needs and develop our tools based on those needs. Three scoping meetings with over 140 planners, managers, and scientists were held. In addition, a subset of these attendees took part in an Outer Coast Focus Group to help beta test the North-central coast flood map and a San Francisco Bay Advisory Committee currently advises on the development of the Bay flood map. 3) Three areas of technical assistance is provided: 1. Targeted Trainings to agency/org staff on how to utilize the OCOF decision support tools and apply them to relevant on the ground projects; 2. Integration Support for organizations that want to bring OCOF’s SLR scenarios into their own GIS environment or decision support tool; and 3. Technical Assistance Engagement for organizations that want to use OCOF in a planning process and need assistance with scenario planning, tool modification or application, etc.
10GENERAL Top Three Limitations As succinctly as possible, list the top three weaknesses or limitations that coastal planners or managers might encounter using this tool. 1) Map should not be used for site-specific decisions (supplement with direct field measurements of elevation), as wider-area analyses are more robust than point-by-point mapping; 2) Levee data are incomplete, and maps/analyses incorporating levees assume condition good and heights infinite; 3) No physical modeling of storm surge or waves on top of sea level rise. 1) Inundation scenarios do not include coastal storm surge, riverine flooding, erosion or other coastal processes; 2) Appropriate for use as a screening-level or planning tool allowing zoom in scale of approximately 1:18,055, but provides map services and data download for more in depth analysis. 3.) Includes fully enclosed federal levees as mapped by the USACE National Levee Database. Partially enclosed, regional, or local levees have been added in certain locations. 1) ONLINE-ONLY: No ability to access the tools with limited or lack of connectivity; 2) USER-FRIENDLINESS: Not catered to general public, so training is requirement to engage stakeholders so they can fully utilize the tool and understand the data and analyses; 3) COMMUNICATIONS: With so many tools now available on the web, it is hard to decipher the niche and therefore use of this tool relative to others that address similar issues 1) Elevation dataset is inconsistent in terms of resolution and vertical accuracy, 2) Shoreline location is inexact and probably subjective, 3) Flooding is classified by depth only and does not take into account the flow pathway (i.e. are low lying areas hydrologically connected) Same as Pacific Institute and CoSMoS (original Cal-Adapt site); under development (Cal-Adapt 2.0). 1) No side by side comparisons of scenarios or overlays of different scenarios are provided except in the "Detailed View" which requires more technical expertise (overlays are possible there) ; 2) Doesn't currently model projections of shoreline change specific to SLR and storm scenarios; 3) Labels or tags are not currently provided to help users delineate areas of interest, infrastructure, etc. and actual parcels can't be delineated.
