HYDROLOGY, Allegheny County, PA

Hydrology data include spatial datasets and data tables necessary for documenting the hydrologic procedures for estimating flood discharges for a Flood Insurance Study, which includes the hydrologic data expected by FEMA for new riverine studies. (Source: FEMA Guidelines and Specifications, Appendix M). This Flood Insurance Study was produced by RAMPP JV (Dewberry, URS, ESP) for FEMA Region III.
