Planning commission denies proposed code rounding amendment, citing unintended consequences

The Dayton Planning Commission voted unanimously on Jan. 8 to deny a proposed ordinance amendment that would have rounded measured lot areas for zoning calculations.

Staff explained the change would have caused whole‑number rounding (for example, converting 1.5 acres to 2.0 acres) and warned of unintended consequences across the code where units mix acres and square feet. Commissioners offered an example in which rounding could change the base measurement used for animal‑unit calculations and thereby alter whether a property qualifies for keeping livestock.

After a brief public hearing with no speakers, the commission made a motion to deny the amendment and voted 5‑0 to reject the proposed rounding language. Commissioners emphasized that variances remain the appropriate tool for small numeric adjustments rather than a blanket rounding change.
