Planning committee approves Summit Creek G1 Phase B final plat; off‑site sewer work required

The Woodland Hills Planning Committee voted Aug. 20 to approve the final plat for Summit Creek G1 Phase B, part of the development’s approved development agreement. The developer said the final plat mirrors the preliminary plat with minor engineering changes and removal of one lot (to be platted in a later phase) because of steep driveway topography.

Becky Gade, representing the developer, told the commission the removed lot (identified in materials as Lot 237) would be platted with the final phase to avoid a steep driveway; the developer plans to reconfigure access from a future road to provide a safer driveway. She said all lots in the phase now have water deeded to the city and that construction will require an off‑site sewer line down the canyon to the existing tie‑in point near the mailboxes and onward to the Payson Sewer Treatment Plant.

Engineers and staff reported the off‑site sewer will be gravity‑fed rather than pumped, a design chosen to avoid long‑term pump maintenance for the city. The city engineer’s review required a 10‑foot access corridor alongside the sewer line so the city can service the infrastructure; the developer said that corridor will be established during construction. The developer also said retention ponds must be built and that trees removed during construction will be mulched and handled per the development agreement.

A planning commission member moved to approve the final plat; the motion was seconded and passed in a voice vote. Staff noted the project likely must be forwarded to City Council under the city’s older subdivision ordinance tied to the development agreement, and staff will confirm the schedule for council consideration.

The developer said the broader Summit Creek master plan includes roughly 135–140 lots and that about 80 lots have sold; the current phase moves the project toward completion with one remaining future phase after this plat.
