Jackson County planners review A-1 zoning rewrite; commission removes a multifamily access clause

Jackson County Planning and Zoning Commissioners spent the bulk of a May work session reviewing proposed revisions to the county’s A‑1 (agricultural) zoning chapter, discussing new tables for permitted uses and parking, treatment of elder/group homes, rules for cell towers and extraction sites, and whether the county should defer to Iowa Department of Natural Resources (DNR) standards for underground storage tanks.

The draft, prepared by county staff and presented by Laura, replaces long prose lists with standardized tables that list principal and accessory uses, required parking and development regulations. Commissioners discussed special‑exception rules the board of adjustment uses when granting variances and identified several places where existing, subjective language could be tightened or replaced with numeric separations or references to state rules.

Why it matters: The A‑1 district covers most of Jackson County. Changes to parking, setbacks and special‑exception rules affect how small residential conversions, agricultural services and limited industrial activities can operate on farmland and in older, pre‑zoning subdivisions such as Leisure Lake.

Most significant discussion points

- Parking for elder and family group homes: Commissioners debated whether to keep the draft’s one‑half parking space per dwelling unit standard for elder/group homes — a ratio the presenter said aims to limit impervious surface — or to require one space per unit. Staff said the one‑half‑space minimum was simple to change and agreed to revise the table if the commission preferred 1 space per unit. The transcript records commissioners noting that state law treats elder/group homes like single‑family dwellings, and that assisted‑living or nursing facilities should be considered separate uses with higher parking needs.

- Cell towers and aircraft protection lighting: Staff and commissioners reviewed a proposed provision requiring aircraft detection/lighting systems (ADLS) for new towers “unless prohibited by FAA regulations.” Commissioners agreed to change permissive wording (“may”) to mandatory wording (“shall”) while preserving a limiting clause that defers to the Federal Aviation Administration where the FAA expressly prohibits ADLS…
