KITTITAS COUNTY DEPARTMENT OF PUBLIC WORKS PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS STUDY SESSION STAFF REPORT STUDY SESSION DATE: January 8, 2018 TOPIC: Currier Creek FEMA Floodplain Mapping Update ACTION REQUESTED: No Action Required LEAD STAFF: Mark R. Cook RECOMMENDATION: No action required by the BOCC at this time. BREIFING SUMMARY: • Innovative re -mapping of Currier Creek floodplain and floodway has been approved by FEMA • Currently in the notice period • Public meeting is planned • Coordination with County Assessor's Office • Future remapping efforts (Whiskey and Mercer Creeks) BACKGROUND: For the past several years, staff has been working with a consultant (Watershed Science and Engineering) developing a new floodplain map for Currier Creek (EXHIBIT 1). The BOCC was last briefed on project progress in March of 2017. In mid-November 2017, we received final acceptance of our modeling results from FEMA (EXHIBIT 2). We have obtained concurrence from the City of Ellensburg (EXHIBIT 3) on acceptance ofthe revised mapping. Notice was published in the daily record on 12-28-2017 and again on 01-04-2018 (EXfIIBIT 4). DISCUSSION: Public Works has completed the required noticing of remapping from FEMA. We are now moving forward in the Letter Of Map Revision (LOMB) process. Staff desires setting a public meeting and conducting an open house sharing our results with impacted county and city residents. During the meeting, we advise residents on the LOMR process and offer technical assistance to those desiring support from Flood Control Zone District (FCZD) staff. It is our understanding that the BOCC does not need to formally adopt the revised maps — as this is done with the LOMR by the signature of the FCZD Administrator.
