Summary

Description

Recent developments in digital terrain and geospatial database management technology make it possible to protect this investment for existing and future projects to a much greater extent than was possible in the past. The minimum requirement for hydraulics data includes input and output files for all hydraulic models and spatial datasets that are needed to implement the models. (Source: FEMA Guidelines and Specs, Appendix M). This Flood Insurance Study was produced by RAMPP JV(Dewberry, URS, ESP) for FEMA Region III. Development of a hydraulic model to provide water-surface elevations for floodplain mapping requires significant investment in time and resources to obtain and process topographic survey data including cross-section and bridge surveys. The objective of this Hydraulic data submission is to archive the hydrologic data for a study in a database such that it can be revised and used with minimum effort in future Flood Insurance Studies or map revisions.
