Vernonia council adopts updated flood‑hazard rules, closing map 'holes' and tightening improvement standards

The Vernonia City Council on Dec. 2 adopted Ordinance No. 947, a text amendment to Title 9 Chapter 9‑05 that city staff said will correct mapping gaps and clarify how the city enforces flood hazard standards. Chair Rick Hobart opened and closed the public hearing and presided over the unanimous adoption by council vote.

City staff summarized the measure as largely technical but with three substantive changes: filling small holes in the special flood hazard area map so previously elevated properties remain regulated, explicitly applying the 50% 'substantial improvement' threshold when damage or improvements exceed half a structure’s value, and adding basic standards for recreational vehicle parks plus lease restrictions for flood‑mitigation lots. Planning staff summarized the map change, saying, “We’re just filling in these little tiny holes,” and gave examples of homes previously elevated with FEMA funds that would otherwise be vulnerable if rebuilt at ground level without the amendment.

During council questioning, staff said the amendment is intended to align the city code with FEMA and state expectations while keeping the city eligible for the National Flood Insurance Program. After public testimony and deliberation, a councilor moved to adopt Ordinance No. 947; the motion was seconded and carried. The chair noted this was the first and second reading by title only and that the ordinance will take effect in 30 days.
