Summary
Unincorporated Utah County maps Wildland-Urban Interface (WUI) fire zones using the State of Utah's WUI overlay, and Chapter 6.11 of the county code layers special construction, water-supply, access and vegetation rules onto any Large Scale Development, recreational resort, mountain home subdivision or freestanding structure that falls inside that mapped overlay.
This chapter applies to "Large Scale Developments" which include: Recreational Resorts, Mountain Home Developments and Subdivisions in the Wildland/Urban Interface lands, and structures not included within a platted Large Scale Development. The specific needs for fire prevention in these high fire prone areas are subject to the regulations of this chapter are delineated on the most recent version of the Wildland Urban Interface fire overlay map as promulgated by the State of Utah, incorporated herein by reference. The provision of both UCC 6.08 and UCC 6.09 shall apply to all areas of the Wildland/Urban Interface shown in the aforementioned map.
Full Breakdown
010 defines the Wildland/Urban Interface (WUI) as the area shown on 'the most recent version of the Wildland Urban Interface fire overlay map as promulgated by the State of Utah,' which the county incorporates by reference rather than drawing its own boundary. 11 attaches to any 'Large Scale Development' inside that map: recreational resorts, mountain home developments, platted subdivisions in WUI lands, and structures not included within a platted Large Scale Development. 080 bans fireworks outright. 09, so anything already prohibited countywide is prohibited more strictly inside the WUI map.
Because the boundary is the state's overlay map rather than a fixed legal description in the ordinance text, a parcel's WUI status can shift as the state updates the map, and the Fire Marshal in the Bureau of Fire Prevention (Community Development Department) makes the final determination for a given site plan. This chapter reaches only unincorporated land; Provo, Orem, Lehi and the county's other cities administer their own WUI or wildfire-zone rules under their own codes.
Violations & Fines
Wildland/Urban Interface requirements are part of the county's adopted Fire Code, and UCC § 6.06.070 makes violating 'any of the provisions of this chapter' a class B misdemeanor, with each day of noncompliance a separate offense. Under the general penalty at UCC § 1.04.010, a class B misdemeanor carries up to a $1,000 fine and six months in the county jail, and the Fire Marshal can withhold occupancy approval until a site complies.
