(3)In areas identified on the Benton County Zoning Map as High-Protection Floodplain, the following shall apply:(a)Removal of vegetation from the floodplain is prohibited, except for the following purposes:(A)Removal of a hazard tree which poses an immediate threat to life or property. Tree removal shall comply with the following standards:(i)The stump and root wad of any altered tree shall remain undisturbed in place;(ii)Any tree removed is required to be replaced by like native species or alternate approved native species.
Full Breakdown
Benton County's Floodplain Management Overlay Zone applies extra rules on top of its general floodplain construction standards wherever the county's zoning map marks land as High-Protection Floodplain within the Corvallis Urban Fringe. 700(3)(a), removal of vegetation from the floodplain is prohibited outright except for a specific list of purposes: hazard-tree removal, maintenance of pre-existing lawns and landscaping, approved stream or wetland restoration, removal of noxious or invasive weeds, native-plant substitution, water-dependent development, a limited fire fuel-break, and a few similar exceptions. 700(3)(a)(A) sets two conditions on the removal itself: the stump and root wad of the altered tree must remain undisturbed in place, and any tree taken out must be replaced with a like native species or an alternate approved native species.
700 instead restricts what a private property owner may cut in the mapped High-Protection Floodplain even for safety reasons. Developers and homeowners in this overlay are encouraged to schedule a pre-application conference with Community Development before altering any floodplain vegetation, since the standard for what counts as an allowed exception, and what replanting satisfies it, is determined by that department.
Violations & Fines
Removing floodplain vegetation, including a tree, outside the listed exceptions, or removing a hazard tree without leaving the stump and root wad undisturbed or without replacing it with a native species, violates BCC Chapter 83's Floodplain Management Overlay standards. Like other Development Code violations, this is enforced through Chapter 31's escalating process (verbal notice, written notice, notice to comply, stop-work order) that can end in an infraction citation carrying a fine of up to $500 per day, or $1,000 per day for a continuing violation, under §§ 31.125 and 31.135.
