Peoria County Project – starting from scratch
USGS Orthophoto base map; 2011 aerial photography Topographic Data: LiDAR funded by IDOT District 4: (Spring,
2012 data acquired by Aerometric) * Illinois River BFEs from USACE 2004 study Zone AE floodplain boundaries re-delineated to match
topographic data Zone A floodplain boundaries derived from “base level”
engineering models Incorporate effective LOMRs Update levee information – TBD Update Flood Insurance Study (FIS) Datum conversion to NGVD 1929 to NAVD 1988: -0.271 feet
*must meet quality standards

7 effective LOMRs (1/1/1970 - 6/29/2012)
1 CLOMR: 11-05-1344R, City of Peoria, STARR, Komatsu America Corp (Project ID), Illinois River

Please check the LOMC list for accuracy and completeness!
DO YOU NEED A LOMR?
A changed circumstance (manmade) almost always requires a LOMR. It is the responsibility of the community to obtain the LOMR.
Examples of when a LOMR is needed: a new bridge over a studied (AE) stream a new flood structure (reservoir, levee, dam) a stream that has been channelized, moved, or submerged
in a culvert. a stream moved due to a new subdivision or other
development Installation of storm sewers
