Planning commission approves separation of retention basin from Lot 116 with condition that city accept donation; front setback change limited

The Grantsville Planning Commission voted unanimously to approve a proposed plat amendment for Matthew Meadows that separates a retention basin from Lot 116, on the condition the basin be donated to the city and that the city explicitly agree to accept the parcel. The developer had proposed separating the basin so it could be used for a future park; the developer has proposed amenities such as pickleball courts and parking in later discussions with city council.

Near-neighbors spoke at the public hearing, most prominently resident Matthew Curry, who said he lives at 449 Durfee Street, directly across from the basin, and expressed concern about grading, watershed and potential flooding. “Durfee Street's been raised so many times. It's a 4½-foot drop off into our driveway…we've already had water issues in our garage in the winter of 2023–24,” Curry said. Curry said he could find no engineering reports in the packet and asked to be included in further discussions.

Longstanding resident and public commenter Gary Pinkham raised several concerns: whether the developer or a homeowners association would be responsible for maintenance; whether the lot subdivision created a new privately owned parcel; and whether reducing certain side setbacks (from 15 feet to 5 feet on one side in the proposed zoning changes) would push space used for RVs and trailers into front yards and streets, causing code enforcement problems.

Planning staff said the developer has proposed donating the parcel if the city wants it as a park; if the city declines, maintenance responsibility remains with the developer or property owner under existing ordinances. Staff also said the basin is approximately an acre in surface area and roughly 6 to 8 feet deep.

Commissioners debated the setbacks requested elsewhere in the proposal. Some members supported allowing a 30-foot front setback in the R zoning as proposed, while preserving a 15-foot side yard on the side typically used for RV parking. Several commissioners said they would support separating the basin only if city council agrees to accept and maintain it; the approved motion included a condition that the separation proceed only if the city formally agrees to receive the parcel as a park. The commission approved the separation and the single front-setback change (30 feet) by unanimous vote.

Commissioners also asked staff to forward concerns raised during the public hearing to city council — specifically maintenance responsibility if the city declines the parcel, the basin’s depth and potential for standing water, access and parking for any future park, and grading/watershed impacts raised by neighbors. The developer will return to council in May with more detailed park plans.
