Staff outlines Mac Canyon master development agreement that ties rezone to parks, trails and commercial dedication

Grantsville planning staff presented a proposed master development agreement for the Mac Canyon subdivision on March 17, outlining conditions the city would require in exchange for a rezone.

Staff explained that the MDA would authorize a rezone to R‑112 provided the developer dedicates collector roads, two miles of trails, multiple ball fields and 2.7 acres of commercial property to the city. "The approval of the agreement is the approval of the rezone," staff said, and warned that failure to meet the agreement's terms would cause the property to revert to R‑1‑21 zoning.

The developer described a strategy of using smaller quarter‑acre lots to finance community amenities and to lower overall water demand; he said front yards would be installed with xeriscape by the developer to reduce the chance that owners never complete landscaping. He also cautioned that the commercial parcel might not be marketable immediately and could take "6 to 8 years" to attract a gas station or other commercial use, and asked for flexibility in the MDA's commercial‑dedication trigger.

Staff and commissioners discussed options to delay the commercial dedication trigger to a later building‑permit milestone and said any such change would need legal review and an amendment to the MDA. Commission members asked whether the development would be HOA‑managed and who would maintain parks; the developer said the HOA would handle some controls but expected the city to maintain major park spaces and ball fields.

No formal vote was taken on the MDA at this meeting; the presentation was for discussion only and staff said the rezone and MDA would return for formal review once details are finalized.
