LETTER OF PERMISSION: The City of Rogers is proposing to extend County Road (CR) 117 a distance of 1,380 feet, from County State Aid Highway (CSAH) 101/Brockton Lane to a future southern entrance street in the proposed Laurel Creek Residential Development.
PROJECT DESCRIPTION AND PURPOSE: The City of Rogers is proposing to extend County Road (CR) 117 a distance of 1,380 feet, from County State Aid Highway (CSAH) 101/Brockton Lane to a future southern entrance street in the proposed Laurel Creek Residential Development. The CR 117 Extension would be a four-lane divided minor arterial roadway located on a new 150-foot-wide road right-of-way. It would include four 14-foot-wide driving lanes with 10-foot-wide bituminous trails on north and south sides of the road.

Project
PROJECT DESCRIPTION AND PURPOSE: The City of Rogers is proposing to extend County
Road (CR) 117 a distance of 1,380 feet, from County State Aid Highway (CSAH) 101/Brockton
Lane to a future southern entrance street in the proposed Laurel Creek Residential
Development. The project is located in the southeastern part of the City of Rogers, formerly
known as Hassan Township. The CR 117 Extension would be a four-lane divided minor arterial
roadway located on a new 150-foot-wide road right-of-way. It would include four 14-foot-wide
driving lanes with 10-foot-wide bituminous trails on north and south sides of the road.
The CR 117 Extension is proposed to meet the need for a safe and efficient transportation
network in the City of Rogers and northwestern Hennepin County, and to provide:
1. The initial segment of an east-west arterial roadway that would connect four other arterial
roadways in southeastern Rogers and southwestern Dayton;
2. Functional traffic circulation;
3. A reliever route that reduces congestion and improves route choices; and
4. Consistency with local and regional transportation planning efforts.
NAME, AREA AND TYPES OF WATERS (INCLUDING WETLANDS) SUBJECT TO LOSS:
Roadway construction would result in the permanent discharge of fill material into approximately
2.34 acres (101,823 square feet) of a seasonally flooded basin and shallow marsh type wetland
complex.
ALTERNATIVES CONSIDERED: The Applicant considered two alternatives that would avoid
wetland impacts on the site, a re-route and a bridge alternative, but determined that both
wetland avoidance designs were not practicable because they would not meet accepted
engineering standards and practices.
Alternative project alignments were also considered and found to be impracticable. Each
alignment was evaluated for its potential to:
1. Meet the purpose of the current CR 117 Extension proposal;
2. Fulfill the ultimate future need for an east-west arterial roadway connecting CSAH 116,
CSAH 101, Interstate 94, and CSAH 81; and
Page 1 of 2
3. Minimize wetland impacts.
North Alignment Alternative: This alternative is not practicable because it is routed north-south
and therefore it would not provide the necessary east-west connection.
Short-Term Wetland Avoidance Alternative: This alternative would increase wetland impacts
associated with the next extension of CR 117 to the west. If the proposed junction of CR 117
and CSAH 101 were shifted north, this alternative would also increase wetland impacts
associated with the next extension of CR 117 to the east.
South Alignment: This alternative is not practicable because it would include a long crossing
through a large wetland complex, and would impact more wetland than the proposed
alternative.
Proposed Alternative: The Applicant states that they chose this alternative because it meets the
three goals listed above more effectively than any other alternative alignment. It would include a
future wetland crossing located near the narrowest part of a large wetland complex.
COMPENSATORY MITIGATION: The Applicant has proposed to compensate for unavoidable
wetland impacts associated with this project, at a 2:1 ratio, via construction of a permitteeresponsible mitigation (PRM) site adjacent to the project site. The proposed PRM would
generate a minimum of 4.6751 wetland credits. The Applicant is intending to submit a final
mitigation plan for this project soon.
