Belgrade City Council spent the entirety of its May 11 workshop discussing mandatory stormwater management regulations coming to the city in 2027. Kamery Yulia, Director of Public Works, briefed the council on MS-4 (Municipal Separate Storm Sewer System) designation, which the Montana Department of Environmental Quality will impose when its general permit renews later this year. Belgrade crossed the 10,000-population threshold at the last census, triggering eligibility for state-level stormwater regulation. Yulia emphasized the city cannot avoid the designation and will join Butte and Kalispell as discretionary MS-4 communities in Montana. Formal notification is expected in October 2026, giving Belgrade 180 days to obtain permit coverage by March 2027.
The presentation highlighted both the regulatory timeline and compliance costs. Belgrade must submit a Notice of Intent, complete GIS mapping of all stormwater infrastructure within city limits and a one-mile buffer zone, and implement six minimum control measures including public education, construction site management, and comprehensive staff training. Within five years, the city must develop a 200-300 page stormwater management plan. City Manager Neil flagged a jurisdictional challenge: enforcement may require an interlocal agreement with Gallatin County for the buffer zone outside city limits.
The bulk of discussion centered on funding through a proposed stormwater utility. Yulia presented three budget scenarios ranging from $1 million to $1.9 million annually, translating to monthly residential rates of $8.68 to $16.17 per quarter-acre lot. The Mayor and most council members leaned toward Scenario 2 ($1.6 million), though concerns about public acceptance ran high. Council Member McGee connected the proposal to recent failed school levies, warning of substantial education challenges ahead. Council Member Simon cautioned that underfunding would replicate past water rate problems. Staff will develop a potential middle option before June's first reading on the utility creation ordinance.
