Sterling Chateau #5 FEMA LOMR Application
City of Vacaville
Using Flo-2D modeling software, West Yost developed a 2-dimensional hydraulic model to route Alamo Creek overflows through a residential neighborhoods for several miles and back into Alamo Creek. Staff also prepared a FEMA LOMR application for a portion of the floodplain.
Engineering services included compiling county LIDAR data using GIS software, developing hydrographs for the flood flow outbreaks based on the FEMA HEC-2 and HEC-1 models developed for the City Flood Insurance Study, and preparing a FEMA LOMR application for a portion of the floodplain. The floodplain resulting from the 2-D hydraulic model very closely matched the actual flooding during the December 2005 flood.
