Planning commission approves accessory units, accessory building and several plat amendments; forwards road amendment to county council

Snyderville Basin Planning Commission members approved four land-use actions during the meeting, including two conditional use permits and two subdivision/plat amendments, and forwarded a road amendment to the Summit County Council.

Why it matters: The decisions clear the way for a third‑floor accessory dwelling unit in a Park City Business Center loft building, a 5,000‑square‑foot accessory structure on a large lot, and two boundary adjustments tied to road dedications that affect the Glenwild and Silver Creek subdivisions.

Accessory dwelling, Altitude Lofts (4123 Forestdale, Building B Unit 2) Planning staff described the application as a conditional use permit for an accessory apartment in the Altitude Lofts development in the Park City Business Center. Staff said the proposed third‑floor apartment meets the minimum 1,000‑square‑foot requirement and that the property owner submitted a letter confirming available parking under an existing parking agreement. Applicant representatives told commissioners the unit would serve the business owner and a small crew (about two to four employees) who stay onsite briefly while performing cabinetry installation work. After a public hearing with no public commenters, a commissioner moved to approve the conditional use permit subject to the findings and conditions in the staff report. A roll call recorded affirmative votes by Commissioner Jeffrey, Commissioner Young, Commissioner Seggerman, Commissioner Nagy and the chair; the motion passed.

Major accessory building (8795 Redden Road) Staff presented a request to construct a major accessory building of approximately 5,000 square feet that would include an accessory apartment. The property already contains minor accessory buildings and a single‑family home; staff said the lot is large enough to allow the proposed additional structures under the county code. No public speakers appeared. Commissioners asked about permitted uses (staff said the approval would prohibit commercial use of the building) and reiterated the need to build strictly to code dimensions. The commission approved the permit by voice vote.

Glenwild Phase 2 boundary adjustment (Common Area Parcel H) Senior Planner Robinson explained a boundary‑line amendment to remove about 9.66 acres from the Glenwild phase 2 common area parcel H so that the county‑owned strip can be dedicated as part of reconstructed Bittner Ranch Road. Staff said the change cleans up a prior omission so the county’s earlier acquisition is reflected correctly on recorded plats. Staff reported notifications to property owners within 1,000 feet and no public opposition. The commission approved the boundary adjustment by voice vote.

Silver Creek Estates Unit 1, Block 3, Lot 1 (Mammoth Drive / Greenville Drive) Staff said the county previously acquired about 0.4 acres of a one‑acre parcel to construct Mammoth Drive; the amendment would adjust Lot 1’s boundary and modify part of Greenfield/Greenville Drive. Because the action affects a public road, staff recommended the commission forward a positive recommendation to the Summit County Council. After no public comment, commissioners voted unanimously to forward the amendment to county council.

Other business Commissioners also approved the March 25, 2025 meeting minutes and appointed a planning commissioner to the Silver Creek Village Design Review Committee. Both were approved by voice vote.

What the record shows: All motions referenced staff findings, conclusions of law and the conditions listed in the staff reports. Staff told the commission they had received a parking‑availability letter for the Altitude Lofts ADU, that the accessory building lot qualifies due to its size, that Glenwild’s boundary change is retroactive to reflect county ownership of a road corridor, and that the Silver Creek amendment must go to county council because it modifies a public road.

Next steps: The Glenwild and Silver Creek amendments will be recorded and, in Silver Creek’s case, considered by the Summit County Council for final approval; the approved permits may proceed to building and permit review as applicable.
