Summary
Inside the Pine Valley Overlay Zone, the county's landscaping standard tells homeowners to clear flammable growth from around their houses: keep twigs, leaves, shrubs, dead grasses, and brush away from the building perimeter. It's framed as encouragement rather than a cited mandate, layered on top of the countywide wildland-urban interface building code.
Landscaping: In order to preserve the rural nature of Pine Valley, it is recommended that landscaping incorporates local Utah native plants... It is encouraged to create a defensible space around residential buildings by keeping twigs, leaves, shrubs, dead grasses and brush away from the perimeter of the structures. Washington County Community Fire Planning recognizes that many communities are at risk for wildland fires and provides the following link to reduce the risk around your home.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-17: Code current through: Ord. 2026-1329-O, passed 8-18-2026).
Full Breakdown
" The same subsection points residents to the Dixie National Forest's native-plant list and reminds them that "Washington County Community Fire Planning recognizes that many communities are at risk for wildland fires," linking out to the National Fire Protection Association's Firewise USA wildfire-safety program. C, which does impose enforceable access-road, water-supply, and defensible-space conditions on new construction in mapped WUI areas; Pine Valley's overlay adds a landscaping recommendation on top of whatever the WUI code already requires for the specific structure. Because the overlay zone was adopted to preserve Pine Valley's "rural, historical and mountain village characteristics" under Section 10-29-1, the defensible-space language reads as neighborhood guidance rather than a numeric clearance standard with a measured distance, unlike the WUI code's structural requirements.
Homeowners inside the Pine Valley Overlay boundary shown on the county's General Plan and zoning maps are the ones this specific provision reaches; it does not extend to other unincorporated communities, which fall solely under the countywide WUI code adopted in Title 9.
Violations & Fines
The Section 10-29-4.C.2.b language is written as encouragement, "it is encouraged to create," not as a mandatory clearance standard, so it carries no fine or citation of its own inside the Pine Valley Overlay Zone. Any enforceable wildfire construction requirement for a given lot still comes from the countywide Wildland-Urban Interface Code adopted at Section 9-1-4.C, enforced through the ordinary building permit and inspection process.
