FEMA open house to display new floodplain maps

FEMA has a new digital map and invites those interested persons are invited to an Open House on Thursday, Aug. 20, from 6:30 p.m. to 8:30 p.m. at the Jackson County Library, located at 205 S. Central Ave. in Medford..  Representatives from Jackson County, Oregon Land Conservation and Development (DLCD), the Federal Emergency Management Agency (FEMA), Northwest Hydraulic Consultants, Inc (NHC), and local communities will be on hand to discuss a Flood Insurance Study revision recently completed in Jackson County and incorporated areas. 

The purpose of the Open House is to provide an opportunity for officials and the citizens of Jackson County and incorporated cities to become familiar with the new digital maps and their role as the primary regulatory tool used under the National Flood Insurance Program (NFIP) and the insurance industry to regulate floodplain development and rate flood insurance policies.

The people most directly affected by the issuance of this study and those owning property and/or living in the identified flood hazard areas.

During the Open House, staff will be available to address mapping, insurance issues, and regulatory requirements established by the NFIP.  The DLCD will have representatives in attendance to address flood protection standards and state programs.  Information on mitigation techniques for homeowners to help reduce future flood damage will be provided.  Agency floodplain and/or building and zoning staff and engineers will be available to answer questions about local flood protection and permit requirements.

This revision was prepared through a partnership between the U.S. Department of Homeland Security’s Federal Emergency Management Agency and NHC.  This revision updates the Flood Insurance Rate Maps (FIRMs) showing the area that would be inundated by the one percent annual chance flood (Base Flood or 100-year flood)

Changes in this revision include new geo-spatial digital data for use with local Geographic Information Systems (GIS).  The maps will provide countywide coverage noting new or revised political boundaries.  The maps will also use a new vertical datum projection based on NAVD 88 and follow a map panel layout based on the U.S. Geological Survey (USGS) 7.5 minute quadrangle map grid. 

The hydrologic and hydraulic analyses were revised on Daisy, Elk, Griffin, Horn, Jackson and Mingus Creeks within the City of Central Point and where appropriate and available, topographic data and aerial photography were used to adjust floodplain and floodway boundaries for the remaining flooding sources.

These new geo-spatially referenced digital maps will be used by federally-regulated lending institutions and insurance agents in determining who must purchase flood insurance and the cost of that insurance should it be necessary.  In addition, the maps will be used by city and county officials for floodplain management and permitting purposes.
