UDO Postponed: County Draft Would Replace Agricultural Zoning with 'Rural Residential' and Open Large Acreage to Denser Development

# What changed in the UDO draft Steve Hunley reports that the most recent draft of Knox County's Unified Development Ordinance eliminates the Agricultural/Residential zoning category. Instead, land now zoned agricultural would become a new "rural residential" category. While that sounds similar, the practical effects differ sharply.

# How density would increase Under the existing agricultural zoning, single-family dwellings require a one-acre minimum lot. The proposed rural residential zone would generally keep a one-acre minimum but allow higher density when certain conditions are met. Specifically, on properties of five acres or more that have both sewer access and adequate, classified road frontage, developers could build up to two dwelling units per acre with a minimum lot size of 5,000 square feet.

# Rezoning without public hearings A central point in Hunley's column is procedural: where sewer and a classified road are present, the draft would permit subdivisions and denser development without a hearing before Knoxville-Knox County Planning or the county commission. That removes a public rezoning step and shortens the path for developers to obtain vested rights to build subdivisions on large parcels.

# Scale and likely consequences Hunley points to the scale of the change: the draft would affect roughly 170,000 acres inside Knox County. He argues that converting that acreage to rural residential under the new rules would accelerate conversion of open land into subdivisions, increase traffic on already strained roads, and reduce remaining green areas to scattered lots amid new construction.

# Local context: growth, housing costs, and taxes

# Examples and road capacity concerns Hunley references specific local development trends and road problems to illustrate his point. He suggests certain corridors are already being transformed by development (he names John Sevier Highway). He also describes citybuilding patterns—large apartment towers and related traffic on major roads such as Chapman Highway—and notes recent bridge closures that limit capacity and funnel traffic onto fewer routes.

# Immediate takeaway for residents If the UDO draft becomes final, homeowners on larger rural parcels could see their land redeveloped or subdivided without the same local hearing process that exists today. That would alter the character of parts of the county, increase housing supply in ways that favor developers, and put additional pressure on roads and services where sewer connections and classified roads exist.

# Next steps noted in the column Hunley says the change will soon come before the Knox County Commission. The column frames the UDO revisions as a major local decision affecting zoning, development patterns, traffic, and how residents can participate in zoning changes.
