New neighborhoods are popping up quickly along the Cottage Grove-Woodbury border, filling in fields and farmsteads and prompting leaders to collaborate more on planning and projects as the cities grow toward each other.
The best recent example is the HERO Training Center, a public safety training facility that will be jointly owned and operated by the south Washington County cities when it opens in October.
And Cottage Grove's northern edge is being divided and developed into master-planned communities that look much like Woodbury's.
"I wouldn't say we are one community; we are still distinctly different," said Jennifer Levitt, Cottage Grove's city administrator. "But we have similar visions in how we serve our residents."
Cottage Grove's most recent growth spurt has pushed it to sixth on the list of metro-area communities with the most single-family home construction this year, according to Housing First Minnesota. Woodbury ranks second on the same list.
Most of those new homes are going up in a zone of north Cottage Grove and south Woodbury that remained largely undeveloped only five years ago. The number of residents in the two cities is rising fast.
Both Cottage Grove and Woodbury are expected to grow by more than 20% from 2020 to 2040. In two decades' time Woodbury, now about 70% developed, will likely be nearing the point where it's completely built out.
Cottage Grove isn't expected to hit that mark until after 2050, its leaders say. But by 2040, plans for the East Ravine district include turning much of the city's northern section into low-density residential areas wrapped around green spaces.
