Council considers annexation of 210.9 acres at Moores Mill Road; conservation overlay, septic systems discussed

The Auburn City Council on April 15 considered a proposal from Mitchell Bridal D Farm LLC to annex roughly 210.88 acres along Lee Road 146 (Moores Mill Road), with staff and council members discussing environmental protections, lot configuration and utility limitations.

Planning staff told the council the Planning Commission had unanimously recommended approval at its March 20 meeting. Staff and the project's representatives described the annexation request as coming into the city with the Conservation Overlay District applied because the property is within the Lake Ogletree Watershed; that overlay automatically restricts density and adds site-review requirements intended to protect water quality.

Scott Cummings, the city's executive director of Development Services, said the city had already anticipated a future roundabout at the Society Hill and Moores Mill intersection and had approved funding for the project. A development agreement for the property includes a construction pacing clause that would limit the developer to building no more than 10 lots in a year while the roundabout and related improvements are being completed, staff said.

Staff explained how the conservation overlay allows clustering and lot sizes down to 1.5 acres while requiring a concept plan, site walks with Water Resource Management, and closer review of lot configuration, roads and erosion controls. Council members and staff emphasized that clustering under the overlay commonly trades smaller individual lots for permanent conservation easements or dedicated open space, though dedication to the city would be optional and is not required by the ordinance.

Council members pressed staff about utilities: water service to the site would be provided by the Beauregard Water Authority, the council heard, but there is no municipal sewer in the area. Staff noted that development could result in multiple on-site septic systems (the transcript references a potential of 64 septic systems under one conceptual plat) and that, from a regulatory standpoint, the city cannot prohibit septic systems where they meet applicable standards.

Staff and council discussed wetland and floodplain protections. Eric of Water Resource Management said typical requirements include stream buffers and upland buffers; wetlands and stream impacts would require mitigation or purchase of mitigation credits from a wetland or stream bank, and federal agencies such as the U.S. Army Corps of Engineers and FEMA would have permitting or mapping authority in certain circumstances. City staff said any mitigation or regulatory approvals would be required whether or not the land is rezoned.

Council members also asked whether an expected preliminary plat showing up to 48 single-family lots and 16 conventional lots (a potential 64-unit buildout noted in materials) was final; staff said that plat work and more detailed plans had not yet been submitted for full city review.

The Planning Commission had recommended approval; staff briefed the council on conditions and the conservation overlay requirements. The transcript records detailed staff and council discussion but does not show the final roll-call vote for the annexation in the excerpt provided.
