FEMA floodplains for HGAC 13-County area. This feature includes DFIRM data for Harris County, Liberty County, and Galveston Island. All other areas are currently covered by Q3 data. These areas will be updated as the DFIRM data becomes available. In its continuing efforts to perform hazards mitigation and to improve customer service by expanding the availability of flood risk data, the Federal Emergency Management Agency (FEMA) has released the Q3 Flood Data product. Designed to support FEMA's Response and Recovery activities and flood insurance policy marketing initiatives, Q3 Flood Data will be used in floodplain management, hazards analysis, and risk assessment activities. The product contains a subset of information derived from paper Flood Insurance Rate Maps (FIRMs). While the digital data were developed to support floodplain management activities, they do not replace the paper FIRMs. This data was processed circa 2010.. Disclaimer: This product is for informational purposes only and may not be suitable for legal, engineering, or surveying purposes. It does not represent an official survey and represents only the approximate relative location of features and boundaries. Mapping may not necessarily reflect on-the-ground conditions. This product and those involved in its production make no claims as to the accuracy or reliability of the data, and neither assumes, nor will accept liability for their use.<\/span><\/p><\/div>", "mapName": "FEMA_Floodplains_DFIRM_Q3_2010", "description": "", "copyrightText": "FEMA", "supportsDynamicLayers": true, "layers": [ { "id": 0, "name": "FEMA_Floodplains_DFIRM_Q3_2010", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon", "supportsDynamicLegends": true } ], "tables": [], "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "singleFusedMapCache": true, "tileInfo": { "rows": 256, "cols": 256, "dpi": 96, "format": "PNG32", "compressionQuality": 0, "origin": { "x": -2.0037508342787E7, "y": 2.0037508342787E7 }, "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 1.4892314192838538E8, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "lods": [ { "level": 0, "resolution": 2445.98490512499, "scale": 9244648.868618 }, { "level": 1, "resolution": 1222.992452562495, "scale": 4622324.434309 }, { "level": 2, "resolution": 611.4962262813797, "scale": 2311162.217155 }, { "level": 3, "resolution": 305.74811314055756, "scale": 1155581.108577 }, { "level": 4, "resolution": 152.87405657041106, "scale": 577790.554289 }, { "level": 5, "resolution": 76.43702828507324, "scale": 288895.277144 }, { "level": 6, "resolution": 38.21851414253662, "scale": 144447.638572 }, { "level": 7, "resolution": 19.10925707126831, "scale": 72223.819286 }, { "level": 8, "resolution": 9.554628535634155, "scale": 36111.909643 }, { "level": 9, "resolution": 4.77731426794937, "scale": 18055.954822 }, { "level": 10, "resolution": 2.388657133974685, "scale": 9027.977411 }, { "level": 11, "resolution": 1.1943285668550503, "scale": 4513.988705 }, { "level": 12, "resolution": 0.5971642835598172, "scale": 2256.994353 }, { "level": 13, "resolution": 0.29858214164761665, "scale": 1128.497176 } ] }, "storageInfo": { "storageFormat": "esriMapCacheStorageModeCompactV2", "packetSize": 128 }, "initialExtent": { "xmin": -1.0890337133216726E7, "ymin": 3274232.0350955264, "xmax": -1.0392422098302094E7, "ymax": 3661965.660808818, "spatialReference": { "cs": "pcs", "wkid": 102100 } }, "fullExtent": { "xmin": -1.0786814798613189E7, "ymin": 3292043.239296824, "xmax": -1.0495944432905631E7, "ymax": 3644154.45660752, "spatialReference": { "cs": "pcs", "wkid": 102100 } }, "datesInUnknownTimezone": false, "minScale": 5.91657527591555E8, "maxScale": 70.5310735, "minLOD": 0, "maxLOD": 13, "units": "esriMeters", "supportedImageFormatTypes": "PNG32,PNG24,PNG,JPG,DIB,TIFF,EMF,PS,PDF,GIF,SVG,SVGZ,BMP", "documentInfo": { "Title": "FEMA Floodplains DFIRM Q3 2010", "Author": "", "Comments": "
