Since these are outdoor exposures, they may not be captured through the buildings dataset, but people may gather at campgrounds or parks, or where monetary damages or fatalities were recorded. <DIV STYLE="text-align:Left;"><DIV><DIV>FFRA_Grid: This is a foreign key that relates to the Unique_ID field in the FFRA_Grid table. Campgrounds total: Represents the total number of campground points located within the pixel. This is a priority dataset that would benefit from an outdoor emergency flood warning system.Campgrounds 500_Year_Total: Represents the total number of campground points located within the 500-Year floodplain within a pixel. This is a priority dataset that would benefit from an outdoor emergency flood warning system.Parks Total: Represents the total number of non-city-owned parks intersecting the pixel. Parks represent additional high priority populations that may gather outside the 500-year floodplain that would benefit from an outdoor emergency flood warning system. This is a priority dataset that would benefit from an outdoor emergency flood warning system.Parks 500_Year_Total: Represents the total number of non-city-owned parks intersecting the 500-Year floodplain within a pixel. Campgrounds_500m_of_500_Year: Represents whether a campground is within 500 meters of a 500-Year floodplain.City_Owned_Park: Represents whether a city owned park is within the pixel.</DIV></DIV></DIV> This data was generated by AtkinsRéalis, using the campgrounds and parks datasets provided by Texas Water Development Board (TWDB). campgrounds parks <DIV STYLE="text-align:Left;">Since campground data is provided in point location format, campgrounds may extend beyond the pixels identified as containing the campground point.The FFRA is provided for the 30-county area at a spatial resolution of 1-kilometer by 1-kilometer for better computational efficiency as well as to align with input data with the coarsest resolution among those that were used in this study. In addition, the selection of the 1-kilometer by 1-kilometer pixel grid for processing FFRA can avoid confusion about the intent of the product – a finer resolution may give a false impression about the precision or intent of this study. This study is not intended to site sirens as part of outdoor warning siren systems but to identify flash flood-prone areas that warrant sirens. FFRA with a resolution of 1x1 kilometer can adequately serve as foundational information for identifying flash flood-prone areas that warrant sirens given the audible radius for outdoor warning sirens typically ranging from approximately 1 to 2 miles.</DIV> 0 EPSG 6.2(3.0.1) Parks_Campgrounds Table 83551 OBJECTID OBJECTID OID 4 0 0 Internal feature number.
