Carbon County's own zoning map service (the county's 'County Zoning' layer, queried 29 September 2026 at the center of each area) shows: Section 16, T14S R11E, Valar's Wellington lease, zoned M&G, 'Mining and Grazing Zone' (matching the Trust Lands memo, csite-015); the NW quarter of Section 28, where the RW 453 notice places the claim, zoned RR-1, 'One-acre Rural Residential Zone', and the NE quarter zoned RR-2.5, 'Two-and-one-half-acre Rural Residential Zone' (the notice names both quarters, fld-002); and both parcels of the 'Jurassic Spark' technology park on the 6 October Planning Commission agenda, Section 36 T14S R11E and Section 2 T15S R11E, zoned M&G (dir-015). County zoning does not govern land the United States owns (Utah Code 17-79-306), and about 37% of Section 28's north half is a federal parcel (dir-002); the rest is private land under the county's zoning. What the county's residential zones allow is set by Carbon's development code, which sits on a county site that refuses our reader.
