Project Descriptions: 18 custom homes came within the limit of 100-year floodplain under the new study (DFIRM-2010). Objective of this flood study was to verify the accuracy of data used for the 2010 map revision.

Revised flood study by MHR through Letter of Map Revision (LOMR) brought all 18 homes out of the floodplain.
Services Provided: Detailed studies of effective models, development of hydraulic cross-sections from actual field survey & development of hydraulic model (HEC-RAS), floodplain mapping, and FEMA submittal for map revision through Letter of Map Revision (LOMR).
