Precipitation Isopluvials 25 year storm inches per 24hr

This geodatabase feature class contains gridded 24-hour precipitation frequency datasets for multiple recurrence intervals, including 6-month, 2-year, 10-year, 25-year, 50-year, and 100-year events. The dataset supports hydrologic, stormwater, and flood risk analyses and is provided at a grid resolution of 10m by 10m. These data are used to develop isopluvial maps for determining design precipitation depths used in conveyance systems and hydraulic structure sizing.
