Elbert County commissioners debate smaller-lot options and new aquifer limits in subdivision rules

ELBERT COUNTY — Commissioners and staff spent a March 18 work session probing proposed changes to Article 11 of the county’s subdivision regulations that would alter minimum lot-size thresholds for well-and-septic development, impose limits on use of the Upper and Lower Dawson aquifers for denser projects, and add language intended to prevent off‑site sale or dedication of water rights.

Jennifer, a county staff member who led the presentation, opened the discussion by identifying the two key thresholds in the current chart: a 10‑acre minimum for individual well-and‑septic service and a 5‑acre threshold tied to central water or sewer. "Some changes to the water regulations in article 11 ... I thought it would be a little bit easier to approach it one at a time," she told the board as she outlined possible revisions, including proposals to reduce the 10‑acre standard toward 5 acres and to reduce the 5‑acre standard to about 2–2.5 acres.

Why it matters: board members said the thresholds determine whether landowners can keep individual wells and onsite wastewater treatment systems (OWTS) or are forced into the much higher up‑front cost of central systems or deep aquifer drilling. One commissioner urged a broader range of allowable lot sizes so households who are not large developers could buy smaller parcels and still build, while other members warned that lowering thresholds without careful drafting could push longtime owners into expensive new infrastructure.

The commissioners discussed several possible approaches. Some favored carving out a category that would allow central water paired with individual septic on lots smaller than five acres — for example, permitting central water and septic on 2.5‑acre lots while continuing to limit wells on smaller parcels. Others proposed replacing the minor/major subdivision distinction with a numeric trigger based on number of dwelling units, gross or net density, or total units in a defined area so that larger projects — regardless of lot configuration — would face stricter aquifer limits.

On aquifer protections, staff presented draft language that would require subdivisions that create densities greater than one dwelling per five acres (whether measured by lot size or unit count) to supply water from sources other than the Upper or Lower Dawson aquifers. Commissioners said the intent is to protect neighbors on shallower, long‑standing wells from being forced to redrill if a nearby development increases demand. "We want to protect the citizens that have been here," one commissioner said, stressing concern for fixed‑income residents who might otherwise face unexpected redrill costs.

Legal and economic tradeoffs came into focus. County staff cautioned that applying new restrictions inconsistently could create a takings exposure; codified, neutrally applied rules are more defensible, staff said. Board members noted the rules could also deter some developments: a commissioner said a recent concept project (referred to as Valentine) withdrew after the draft language circulated, and the board debated whether the rules were discouraging useful projects such as an assisted‑living facility. Commissioners also discussed estimates presented in the session — including examples that placed additional per‑lot drilling and infrastructure costs in the tens of thousands to potentially six‑figure ranges depending on depth and configuration — and stressed those numbers are approximations that depend on site conditions.

A separate proposal would restrict dedicating or selling water rights so that water under a subdivision could remain for on‑site use rather than being transferred off‑site. Commissioners raised transparency concerns and alleged developers sometimes sell or broker water between projects, which one commissioner said can increase housing costs for end buyers; another commissioner responded they were not aware of that practice in all cases. Staff said proposed dedication language could be drafted as a distinct subsection and tied to the revised chart or threshold language for clarity.

Next steps: staff will redraft the chart and the aquifer and dedication language, explore alternative thresholds (units vs. acreage vs. gross/net density), clarify definitions (for example, how accessory dwelling units count), and return to the board in a future work session for further review. No formal votes or regulatory changes were adopted at the March 18 meeting.

Key items remaining: (1) resolve whether thresholds are best defined by lot acreage or unit counts, (2) decide precise triggers that require central systems or restrict Upper/Lower Dawson use, and (3) finalize wording on dedication/sale of water rights and clarify any exceptions. The board set a follow‑up work session for further consideration.
