Planning commission recommends Sun Sage Terrace master plan changes, lot layouts for Phases 3–6

The Grantsville Planning Commission voted to recommend approval to the city council of the Sun Sage Terrace master development agreement (MDA) and the lot layouts for phases 3–6, a subdivision proposal in the R‑1‑21 zone approximately at 1161 West Main Street.

Shelby presented staff findings and maps, describing phase counts (phase 3: 21 lots; phase 4: 36; phase 5: 38; phase 6: 128) and explaining that the developer would provide right‑of‑way for larger collector streets (including a 94‑foot and a 108‑foot half‑width collector) in exchange for allowing a number of smaller lots that fall slightly under the half‑acre standard. Staff said most lots meet code, with a subset at ~90% of the required lot area because of the road cross‑section demands.

Commissioners and staff characterized the proposal as a negotiated trade‑off: the city gains road connectivity and widened arterial/collector capacity while the developer accepts a modest “haircut” in some lots. Commissioners sought clarity about who would maintain stormwater basins and open spaces; Shelby and the developer said the HOA would be responsible for maintaining open space and on‑site retention basins; public roads described in the plan would be dedicated and city‑maintained.

A brief public hearing saw limited comment; the commission then moved to recommend approval to the city council. The motion passed unanimously. The commission asked staff to include engineering and traffic exhibits in the council packet and to confirm HOA/deed restrictions addressing parking and long‑term maintenance.

Next steps: Staff will forward the recommendation and technical materials to the city council for a final decision on the MDA and the lot layouts.
