Commission approves Dry Creek preliminary plat after debate over trails, wells and floodplain

The Gallatin County Commission on April 1 granted preliminary plat approval for the Dry Creek Major subdivision, a 15-lot residential proposal north of Valley Grove, after hearing staff, applicant and public testimony on trails, floodplain constraints, well usage and lighting.

The proposal and waiver: Hayden Kalajiri, planner for the City of Belgrade, introduced the preliminary plat showing 15 single-family lots and a request to provide open space rather than dedicated parkland. Applicant Mark Fasting of Allied Engineering said the subdivision proposes 11.88 acres of open space in lieu of the roughly 1.49 acres of parkland otherwise required. Fasting said the design exception and open-space approach keep the subdivision consistent with adjacent development patterns while delivering a trail amenity for future residents.

Why it matters: The property abuts Valley Grove subdivision and contains riparian areas and mapped floodplain. Staff and the applicant said buildings would be located outside the designated floodplain, with the lowest floor elevation required at least two feet above the 100-year flood elevation. The project includes a community wastewater system (a low-pressure sewer with grinder pumps and a level-2 treatment system) and on-site domestic wells tied to a water allocation letter; the applicant said the larger parent parcel had a 10-acre-foot allocation that applies to the parcel being subdivided and will be monitored.

Public concerns: Multiple Valley Grove residents opposed trail alignment and potential loss of privacy. Nicole Lowry of 409 Old West Trail asked that the absence of street lights be codified in covenants and that the trail be set back from existing homes; Curtis Lindsey asked for enforcement of worker speed limits during construction. Erwin Barr said the strip labelled "Valley Grove Park" on maps is undeveloped and the proposed trail would not tie into an existing trail network. Commissioners and staff discussed the option of making trails a public easement versus private HOA amenity.

Conditions and safeguards: Planning staff recommended, and the commission approved, multiple conditions for final plat, including a well-monitoring program and reporting of metered groundwater use to the Montana Department of Natural Resources and Conservation (DNRC), documentation of the 100-year flood elevation on final plats, construction of required hydrants or a buried tank hydrant if existing systems are not available, and requirements for lot-level setbacks. The commission added a condition directing staff to craft covenant language requiring outdoor lighting to be downcast to limit light pollution.

Commission action: The board first approved a waiver allowing open space instead of dedicated parkland, finding the proposal "provides land permanently set aside for park and recreation use sufficient to meet the needs of persons who will ultimately reside in the development." The commission then approved preliminary plat subject to staff and planning-board-recommended conditions and the added lighting covenant. The Belgrade Planning Board had previously voted unanimously in favor of the project.

Next steps: Final plat approval will follow completion of conditions including fire protection arrangements, final wastewater system design and recorded covenants specifying lighting and water-monitoring obligations.
