Dakota County's physical development committee at its March 14 meeting approved plans for the last segment of the Mississippi Regional Trail, which will cover a two-mile stretch of Rosemount.
The 27-mile Mississippi Regional Trail will connect Hastings to St. Paul. The last piece will join an existing trail segment called MRRT West to Spring Lake Park Reserve.
The committee also rescinded a previous resolution, made in August 2015, which outlined a different layout. That plan was rejected because the county failed to reach an agreement with Union Pacific Railroad to traverse some land it owns.
Commissioner Tom Egan noted that the completion of this trail segment had been discussed by the County Board so many times that he felt like he knew "every square inch" of the area.
An engineering and design firm studied nine possible options for the new trail alignment and then narrowed those options down to two. The committee chose the second one, dubbed the brown option, at the March 14 meeting.
The new trail will cost $12 million to $13 million, require right of way acquisition from seven properties, and involve the construction of two overpasses over railroad tracks. It may also save $1 million to $2 million in the long run because it could connect to the Rosemount Greenway in the future, according to Dakota County officials.
The brown option was the costlier of the two, but board members worried about issues with property owners along the trail if they chose the other option, which would have cost $8 million to $11 million.
Commissioner Mike Slavik said that it felt "like we could build a road" for the amount of money being spent on the trail. Slavik urged county officials to begin negotiations with landowners as soon as possible instead of waiting until summer.
