Impact analysis
The developer projects roughly $6 million a year in recurring city revenue at full buildout, plus one-time construction sales tax — but also more demand for police, fire, water, and schools.
Future residents and businesses, plus current south-siders who gain roads, parks, trails, and neighborhood commercial — and the school district, which faces declining enrollment.
No affordable housing is included in the plan, and commissioners questioned school-walking distances and water demand.

City Council Meeting - FINAL — April 7, 2026
Developers presented a revised proposal for the Mill Town project at 1801 S. Milton Road, featuring 265 multi-family units and commercial space.
