Commission backs new A-3 rural residential district, sending measure to council

The Dayton Planning Commission voted unanimously March 6 to recommend that the City Council adopt a new A-3 zoning district and related comprehensive-plan language to provide an interim framework for large-lot, unsewered residential development in northwest Dayton.

Staff described the A-3 district as an interim tool that allows unsewered residential development at a target density of roughly one dwelling unit per 10 acres while reserving land and planning for potential future urbanization when regional sewer becomes available. The draft ordinance and staff presentation discussed: requiring “ghost” planning that demonstrates how properties might be urbanized in the future; limiting development to no more than 25% of developable land in a project to preserve larger parcels for future use; minimum lot sizes (1.5 net acres as a buildable minimum in some configurations); and protections for wetlands and other natural resources.

Jason (city staff) and others noted the policy background: the Metropolitan Council had reviewed early proposals and told staff Dayton is inside the Metropolitan Urban Service Area (MUSA) and is likely to be served by regional sewer eventually; staff said the A-3 district is designed to balance current landowner requests for flexibility with the Met Council’s long-range service expectations.

Speakers at the public hearing urged both protections for rural character and clearer guidance on access and infrastructure. Larry Gow, a property owner in the area, told the commission he did not object to one-house-per-10-acre density but said he wanted clarity on how roads, utilities and future subdivisions would be handled. Commissioners discussed requiring paved public roads for subdivisions of more than three homes and favored retaining options and case-by-case review.

Commissioners voted 4-0 to recommend approval; staff told the commission the item will go to the City Council on March 25.
