10	GENERAL	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.	A mapping viewer designed to help coastal communities start discussions about coastal flood hazard impacts with maps that show people, places, and natural resources exposed to coastal flooding.	Tool allows mapping of different sea level rise projections in 10 year increments up to 2100. It allows users to compare flooding under different scenarios based on the National Climate Assessment. Inundation can be viewed at different resolutions.	Tool allows mapping of 1) a single sea level rise scenario over 10 year increments up to 2100, 2) mapping of natural coastal resources (marshes, beaches, dunes, etc), 3) mapping of human coastal infrastructure (bulkheads, riprap, docks, etc) and 4) mapping of perferred management stratgies.	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

10	GENERAL	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) Allows users to select a location and explore maps that show people, places, and natural resources exposed to coastal flood hazards; 2) Creates a collection of maps to download or share online to communicate flood exposure; 3) Provides guidance for using the maps to engage community members and stakeholders in conversations about potential coastal flood impacts	1) Easy to use through web browser, 2) Uses consistant and high resolution data specifically avaliable in Virginia, 3) uses sea level rise projections developed specifically for Virginia	1) Easy to use through web browser with downloads avaliable, 2) Uses consistant and high resolution data developed and varified specifically in Virginia, 3) allows for evaluation of sea level rise impacts on a number of different mangement targets	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
10	GENERAL	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) Cannot customize outputs or load additional local inputs directly into the tool; 2) Appropriate for use as a screening-level or planning tool allowing zoom in scale of approximately 1:18,055; 3) Changes or updates to source datasets will not be reflected in the tool until the next data update is completed	1) Sea level rise scenarios were developed on a state-wide basis and may need some extrapolation in different locations due to differing subsidence rates; 2) tool allows user to zoom into parcel level, which should be interpreted cautiously; 3) this tool only shows sea level rise	1) Sea level rise scenarios were developed on a state-wide basis and may need some extrapolation in different locations due to differing subsidence rates; 2) tool allows user to zoom into parcel level, which is appropriate for some data while sea level projections should be interpreted cautiously; 3) maps and reports are generated on the county level only	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
