The Mapleton City Planning Commission on a vote approved the preliminary plat for a new 118‑lot phase of the Mapleton Village residential development, with conditions included in the staff report. The commission’s action followed a presentation by city staff and comments from the applicant, Toll Brothers.

City planner Sean (staff) told commissioners the Mapleton Village project has been on the books for years and that the city originally approved PD‑1 zoning and a concept plan in 2007. The current proposal would develop about 118 lots in four phases, with individual lots ranging “roughly a quarter acre to a half an acre,” about 24 acres of protected open space, and an open‑space commitment of about 37 percent of the site. Sean said the proposed density is about two units per acre, lower than the medium‑density general plan designation cited by staff of roughly three units per acre. He described a connected trail system that will link into the Hidden Hollow and Twin Hollow subdivisions and said the PD‑1 zone allows clustering to protect open space.

Commissioners and residents asked about traffic and connectivity. A commissioner asked whether traffic studies had been done for the new connections; Sean said an initial traffic study existed from the earlier approvals and that an updated study will be required before final plat approval. An applicant representative, Dylan Young of Toll Brothers, said the project team submitted an updated traffic report the day of the meeting and that “everything’s all of the intersections ... run at a ... B level of service or better,” but Young acknowledged the full report was only just received by staff.

Other questions addressed street widths, sidewalks, and trails. Staff said the main residential right of way (Mapleton Estates Drive) is 40 feet and local streets will be 32 feet; staff said 32‑foot local streets can accommodate on‑street parking on both sides while allowing vehicles to pass at slower speeds. Staff also said recent developments had deferred sidewalks previously but that the city will require full sidewalks to be built as part of future infrastructure upfront rather than allowing deferrals. Sean described the transferable development rights (TDR) mechanism that permitted increased density on this property: earlier owners deeded open space to the city in exchange for development rights that were later applied to this parcel.

Staff’s recommendation was approval of the preliminary plat with the conditions listed in the staff report. A commissioner moved to approve the preliminary plat with the staff conditions; a second was recorded and the commission voted in favor. The motion carried.

The approval is for the preliminary plat only; staff said final plat approvals will require updated engineering, an updated traffic study, and the usual infrastructure assurances before individual phases may proceed. The staff presentation referenced required connections out to Highway 89 through the Salisbury development (Mapleton Village Parkway) and the Harmony Ridge Parkway connection; later phases will require additional connections to undeveloped properties to the north.

Planning staff indicated the project uses existing PD‑1 allowances and TDRs previously dedicated to the city. The commission’s approval advances the development to the next (final plat) step, subject to the conditions in the staff report and to the submission and review of the updated traffic study and required infrastructure plans.
