Residents press county commissioners over water, sewer and road risks at Crystal Springs Estates hearing

The Anaconda‑Deer Lodge County Commission heard more than two hours of public comment on a proposed 29‑lot subdivision, Crystal Springs Estates, at a public hearing that drew homeowners, engineers and the developer to the podium.

Residents raised detailed questions about groundwater, sewer capacity, traffic and how enforceable homeowner association covenants would be. ‘‘If there's some kind of covenant to be put in . . . to drop their volume of dispersion of how much well water they can take out,’’ Jack Duffield said, asking for guarantees that neighboring wells would not suffer if 28 new domestic wells were pumped at once.

Carl, the county planning official, summarized the proposal: the project would create 28 new residential lots plus one large lot preserving the existing farmhouse, add a roughly 5‑acre common area, extend sewer to tie into the West Valley Sewer system, and establish an HOA to maintain internal roads and the irrigation system. Carl said the planning board had unanimously recommended denial at its June meeting but that applicants revised covenants and technical materials following public input.

Developer Ken Jenkins of Montana Northwest Company said covenants have been updated to include wildlife protections recommended by Fish, Wildlife & Parks and to assign internal maintenance to the HOA. ‘‘We have a detailed set of covenants that . . . have been modified for the better,’’ Jenkins said, adding that provisions required by the county can be written so they cannot be changed without governing‑body approval.

Brian Throckmorton of 406 Engineers described the infrastructure plan, saying on‑site roads would meet county standards, stormwater would be managed on‑site with retention ponds subject to Department of Environmental Quality review, and sewer sizing will be coordinated with Anaconda Municipal Sewer and DEQ. On water, Throckmorton said each home would have a metered domestic well for indoor use and the developer would supply an HOA‑maintained surface‑water irrigation system fed from existing surface‑water rights to discourage hooking lawns to domestic wells. He summarized the project’s groundwater estimate as roughly 7.84–8 acre‑feet of groundwater for the subdivision and noted Montana law allocates a 10 acre‑foot exempt well amount to certain lots created before 2014.

Many commenters said the hydrology work relied on dated data and urged independent studies. ‘‘Those measurements are 20 to 30 years old . . . we deserve more than that, especially when our livelihood is on the line,’’ Marie Estoppel said, citing well logs used in the SWDAR report. Mark Peterson and others said there were no recent aquifer water‑level measurements and requested newer testing to reflect current development and drought trends.

Residents also pushed back on sewer capacity and stormwater routing, fearing backups and inadequate pipe sizing. Leslie Scott Wolfrook questioned where retention ponds would drain and warned that placing the subdivision egress across Jones Lane would turn Rumsey Street into a fast throughway without sidewalks. Multiple speakers opposed a broad special improvement district (SID) that could obligate neighboring properties to pay for road improvements; developers said an SID waiver offer was intended to show willingness to participate in future neighborhood improvements but that state law requires pro‑rata shares for new subdivisions.

Speakers worried that CC&R protections held only by an HOA can be amended by future owners. ‘‘HOA covenants are not legally reliable for the tools protecting neighboring landowners,’’ Jana Anderson said, urging county conditions that are binding beyond HOA votes.

Developers and engineers responded point‑by‑point: stormwater ponds are sized for infiltration and require DEQ approval; a capacity letter with Anaconda Municipal Sewer has been obtained and DEQ must approve sewer calculations; meters and the surface‑water irrigation system are intended to limit lawn irrigation from domestic wells; and the developer can add covenant language that would require governing‑body approval for certain covenant changes. They offered to bring the hydrology expert who prepared the study to the commission’s next meeting.

The commission did not vote on the subdivision. The chair closed the hearing and said the planning office will set a future meeting when the item returns to the agenda. Routine appointment items followed before the meeting adjourned.

What happens next: the commission must still consider conditions of approval and any required studies or deed restrictions if the proposal returns; residents asked the county to require independent aquifer analysis and clear conditions to protect existing water users.
