Alington Planned Unit Development (Alington Flex Homes)
If approved as revised, it would add hundreds of homes and a commercial area near Sun Valley Drive and Cook Lane — the council is pressing for lower density at the edges and better buffers for existing rural neighbors.
Alington Subdivision Planned Unit Development
If approved as revised, Sun Valley neighbors would get fewer homes behind them and a tall fence, while the city gets a 12-inch waterline, UDOT intersection improvements, and entry-level housing — but residents still worry about traffic, school capacity, and density.
