of the Easton Reach Flood Hazard Assessment was to better understand, communicate, <br />and plan for these flood hazards. <br />The study's results were compared to FEMA's regulatory flood maps. The findings <br />revealed generally wider floodplain extents, with localized areas of both increased and <br />decreased base flood elevations and risk. The regulatory floodway was also determined to <br />require expansion. <br />Per Kittitas County Code 14.08.105, the County must notify FEMA of changes to base <br />flood elevations within six months of receiving new technical data. This notification must <br />include technical or scientific information. The updated data was submitted to FEMA in <br />2023, and the County anticipates an upcoming map amendment. <br />DISCUSSION: <br />Kittitas County will issue a public notice in the paper of record. Staff further recommend <br />mailing an informational flyer to affected landowners. <br />Map changes will take effect approximately 120 days after FEMA approves the Letter of <br />Map Revision (LOMR). A 90-day appeal period will follow the LOMR's approval. <br />During this period, any property owner or lessee who believes their property rights are <br />adversely affected by FEMA's proposed flood hazard determinations may submit <br />scientific or technical data in support of an appeal. <br />Appeals must be submitted to Kittitas County. The County is responsible for collecting <br />and reviewing these submissions, forwarding them to FEMA, and determining —based on <br />the technical information provided —whether to appeal on behalf of the property owner or <br />lessee, all within the 90-day appeal window. <br />FISCAL IMPACTS: <br />The 2025 annual budget includes costs associated with landowner outreach in flood risk <br />areas. <br />ATTACHMENTS: <br />Exhibit 1: Draft informational flyer <br />Page 2 of 2 <br />Public Works "Work Session Staff Report", 2025 <br />
