Summit County Council approved bringing 10 parcels near Kimball Junction into Mountain Regional Water's service area Nov. 4, clearing one step toward supplying the Altus Park City development.
The council, acting as the governing board of Mountain Regional Water Special Service District, voted 2-1 to approve the annexation under Resolution MRW-2026-07, according to TownLift's Nov. 6 report.
The decision adds the properties to the water district's boundaries but does not immediately provide water service.
Mountain Regional General Manager Andy Garland told council members that the district has enough water to accommodate the proposed development, but additional pipelines will be needed.
Property owners responsible for water connections
The annexation includes parcels owned by developer-affiliated Park City Junction LLC, Summit County and High Valley Transit District.
The properties are associated with Altus Park City, formerly known as the Dakota Pacific development.
Under the proposed arrangement, property owners will be responsible for extending water lines from the existing district system.
They must also pay applicable water reservation, standby and impact fees as development proceeds.
The annexation resolution published by Mountain Regional Water specifies that property owners become eligible for district water services after entering into a separate water service agreement.
The annexation itself does not authorize construction of the required pipelines or guarantee an immediate connection.
Development includes affordable housing
Mountain Regional's staff reviewed the annexation request before the county vote.
In an Oct. 13 memorandum, Garland explained that the affected properties are part of a partnership involving Summit County and private developers.
The proposed development is mixed-use, with affordable housing representing a major component.
Garland's memorandum also noted that one of the parcels contains an existing Summit Water well.
According to the memo, Summit Water was unwilling to serve the properties despite infrastructure already being present in the area.
Garland recommended forwarding the annexation request to the Summit County Council for approval.
Mountain Regional's Administrative Control Board subsequently recommended the proposal in a 4-1 vote.
Water demand raises infrastructure questions
During the Nov. 4 discussion, council members considered a request to reserve approximately 450 acre-feet of water annually for the properties.
That amounts to an average flow of approximately 280 gallons per minute.
Garland said the district has sufficient water resources for the request, according to TownLift, but the infrastructure needed to deliver that amount has not yet been constructed.
The issue comes as Mountain Regional evaluates how additional development could affect water availability across the Snyderville Basin.
District officials previously warned that projected demand from future projects could exceed available supplies without new water sources or conservation measures.
Those broader projections do not establish an immediate shortage for the 10 annexed parcels.
Next steps depend on developers
Council member Megan McKenna moved to approve the annexation, and Council member Tonja Hanson seconded the motion. The proposal passed 2-1.
The county's official Nov. 4 meeting agenda identifies the resolution and the 10 affected parcels.
With the annexation approved, the property owners can pursue water service agreements and the infrastructure improvements necessary to connect their properties to Mountain Regional Water's system.
No construction schedule for those water-line extensions was established in the available records.
