{ "currentVersion": 11.3, "serviceDescription": "Virginia Coastal Resilience Master Plan Phase II pluvial (rainfall-driven) flood depth grids. Represents the flood depth at any given location, as calculated by subtraction of the ground elevation from the water surface elevation. \n\nThe CRMP Phase II pluvial production effort sub-divided coastal Virginia\u2019s HUC-12 watersheds into 1,830 smaller sub-catchments. Each sub-catchment represented an area ranging between 3 and 10 square miles to make the models more manageable and support uniform precipitation. The models were created using the USACE HEC-RAS version 6.1 software.\n\nPrecipitation were projections based on NOAA-MARISA predictive intensity, duration, and frequency curves.\n\nComplete documentation of data sources and treatment for model application is provided in the Pluvial Modeling Technical Memorandum here:\nhttps://vadcr-frp.s3.amazonaws.com/Pluvial_CRMP/VACRMP_PluvialModelingReport_Final_20240614.pdf\n\nThere is a total of 5 planning scenarios available: \n\nBaseline data is based on historical and observed data. This data is not recommended for long-term planning purposes but serves as a point of comparison for future conditions. Near Future scenarios are suitable for planning through the next 35 years and are based on climate data most relevant to the period between 2030 and 2060. Far Future scenarios are suitable for planning through the next 75 years and are based on climate data most relevant to the period between 2060 and 2100.\n\nModerate projections indicate a likely future. They represent a \u201cbest estimate\u201d for future conditions, suitable for decisions where more risk is acceptable.\nHigh projections indicate a less likely but possible future with higher sea level rise and precipitation estimates. These projections may be favored for use in decisions with little tolerance for risk.", "name": "CRMP2_Rainfall_DG/Rainfall_DG_NearFutureMod_100yr", "description": "", "extent": { "xmin": -8705215.092097938, "ymin": 4365683.781602433, "xmax": -8357693.629055012, "ymax": 4777222.5166799035, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "initialExtent": { "xmin": -8705215.092097938, "ymin": 4365683.781602433, "xmax": -8357693.629055012, "ymax": 4777222.5166799035, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "fullExtent": { "xmin": -8705215.092097938, "ymin": 4365683.781602433, "xmax": -8357693.629055012, "ymax": 4777222.5166799035, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "sortableFields": "", "bandCount": 1, "pixelType": "F32", "minValues": [ 0.5 ], "maxValues": [ 99.829925537109 ], "meanValues": [ 2.9088302346108 ], "stdvValues": [ 4.4429289472836 ], "hasMultidimensions": false, "pixelSizeX": 3.0480060960121915, "pixelSizeY": 3.048006096012195, "meanPixelSize": 3.0480060960121933, "datasetFormat": "TIFF", "uncompressedSize": 61577305216, "blockWidth": 128, "blockHeight": 128, "compressionType": "LZW", "bandNames": [ "Band_1" ], "allowCopy": true, "allowAnalysis": true, "itemAccess": false, "inspectionCapabilities": "", "noDataValue": 3.3999999521443642E38, "noDataValues": [ 3.3999999521443642E38 ], "minPixelSize": 0, "maxPixelSize": 0, "copyrightText": "", "serviceDataType": "esriImageServiceDataTypeGeneric", "serviceSourceType": "esriImageServiceSourceTypeDataset", "objectIdField": "", "fields": [], "capabilities": "Image,Metadata,Mensuration", "defaultMosaicMethod": "Center", "allowedMosaicMethods": "", "sortField": "", "sortValue": null, "sortAscending": true, "mosaicOperator": "First", "defaultCompressionQuality": 75, "defaultResamplingMethod": "Bilinear", "maxImageHeight": 4100, "maxImageWidth": 15000, "allowRasterFunction": true, "rasterFunctionInfos": [ { "name": "None", "description": "", "help": "" } ], "rasterTypeInfos": [ { "name": "Raster Dataset", "description": "Supports all ArcGIS Raster Datasets", "help": "" } ], "mensurationCapabilities": "Basic", "hasHistograms": true, "hasColormap": false, "hasRasterAttributeTable": false, "minScale": 0, "maxScale": 0, "exportTilesAllowed": false, "supportsStatistics": false, "supportsAdvancedQueries": false, "editFieldsInfo": null, "ownershipBasedAccessControlForRasters": null, "allowComputeTiePoints": false, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": false, "supportsOrderBy": false, "supportsDistinct": false, "supportsPagination": false }, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }
