North/South Corridor Preservation StudyCity of Mayer / Carver County / Mn/DOT: 

North/South Corridor Preservation Study City of Mayer / Carver County / Mn/DOT City Council / Planning Commission Workshop #2 November 6th, 2007

Purpose of Meeting: 

Purpose of Meeting Present Overview of Draft Study Report Need for the Study Study Goal Corridor Objectives & Evaluation Criteria Planning Alignment Alternatives Preferred Corridor Alternative Recommendations & Implementation Next Steps

Study Need : 

Study Need Future Vision – Mayer & Carver County 2030 Transportation Plans identify need for future Minor Arterial roadway corridor Safety – numerous crashes on TH 25 between 82nd Street & TH 7 Traffic Volumes – 2030 volumes on TH 25 forecasted to exceed capacity without expansion; expansion would conflict with land use goals Land Use – changes from agricultural to urban development; desire for pedestrian orientated downtown central business corridor Development Pending – integrate corridor location into development plans, rather than pay for improvements after the area is built up

Study Goal : 

Study Goal “Identify a safe and efficient corridor alignment option for further planning, preservation, and environmental analysis as may be required by the National Environmental Policy Act (NEPA) based on an objective evaluation of alternatives” The study will identify a location for the corridor that considers: Transportation Needs Environmental Features Social/Economic Factors Preservation NOT Construction

Corridor Objectives& Evaluation Criteria: 

Corridor Objectives & Evaluation Criteria Transportation Design Features 45 to 55 mph design speed 150’ right–of–way Interim – 2 lane urban section, Long Term – 4 lane Bike/pedestrian trails Identified access locations (1/2 mile spacing)

Corridor Objectives& Evaluation Criteria: 

Transportation – Other Factors Estimated project construction costs Minimizing number of potential relocations Minimizing amount of new right–of–way Planned intersection improvements at TH 25 & TH 7 Mn/DOT’s purchase of access rights on TH 7 & parts of TH 25 Development of Mayer’s future collector roadway system Corridor Objectives & Evaluation Criteria

Corridor Objectives & Evaluation Criteria – Land Use: 

Corridor Objectives & Evaluation Criteria – Land Use Considerations Location of Existing Development Fieldstone Plats & AUAR Area Mayer Lutheran & City Properties Existing Undeveloped Properties Dakota Rail Regional Trail Severing Ag Land Avoiding & Minimizing Unusable Remnant Pieces

Corridor Objectives& Evaluation Criteria: 

Corridor Objectives & Evaluation Criteria Environmental & Cultural Resources – avoid or minimize impacts to: Prime farmland & ag land severances outside the 2030 growth boundary Wetlands High quality maple–basswood forest (per Natural Resource Inventory) Berliner Lake Known existing or potential historic sites Known cultural resources

Planning Alignment Alternatives : 

Planning Alignment Alternatives Concept A Consistent with Mayer & Carver County 2030 Transportation Plans Most direct route Good connectivity options to downtown Mayer TH 25 traffic volumes in 2030 forecasted to be similar to 2005 volumes Avoids most residential properties (1 home would be relocated) Least impact on Fieldstone plats & AUAR area Achieves desired spacing between collector & arterial roadways, and access spacing on TH 25 Located in 2030 growth boundary – likelihood of right–of–way to be dedicated north of CSAH 30 & interim roadway constructed

Planning Alignment Alternatives : 

Planning Alignment Alternatives Concept B Located in 2030 growth boundary – likelihood of right–of–way to be dedicated north of CSAH 30 & interim roadway constructed Achieves desired spacing between collector & arterial roadways, and access spacing on TH 25 Bisects Fieldstone preliminary platted area & AUAR area Higher project costs due to land acquisition Impacts cohesiveness of the planned community Less direct route than Concept A Less connectivity to downtown Mayer than Concept A

Planning Alignment Alternatives : 

Planning Alignment Alternatives Concept C Located outside of 2030 growth boundary Higher traffic volumes on existing TH 25 Increased safety problems, traffic congestion & ability to achieve thriving downtown atmosphere Bisects Fieldstone AUAR area impacting cohesiveness of the planned community Wetland impacts Does not achieve desired spacing between collector & arterial roadways Least direct route Least connectivity to downtown Mayer

Preferred Corridor Alternative: 

Preferred Corridor Alternative A–1 Shortest in length Likelihood to be achieved sooner (closest to urban growth boundary) TH 25 continues to bisect Berliner Lake (could result in additional impacts when road is widened to 4 lanes) A–2 Resembles City Transportation Plan Bisects maple – basswood forest Requires relocation of 2 homes Wetland impacts Fewer farmland severances than A–3 but more prime ag land impacts When road widened to 4 lanes Berliner Lake impacts avoided Ends 1.5 miles south of CSAH 30 & urbanization is not anticipated in the foreseeable future A–3 Resembles City Transportation Plan Avoids maple – basswood forest, relocation of 2 homes & wetland impacts More farmland severances than A–2 but less prime ag land impacts When road widened to 4 lanes Berliner Lake impacts avoided Ends 1.5 miles south of CSAH 30 & urbanization is not anticipated in the foreseeable future

Recommendations & Implementation: 

Recommendations & Implementation North of CSAH 30 – Preferred Corridor Alternative Conceptual layout & profile developed for 4–lane urban road Factors considered Tie into existing intersections (CSAH 30 &7th Street) Avoid wetlands Minimize grading outside of 150’ right–of–way Bridge over the Dakota Trail Pedestrian underpass connecting the Mayer Lutheran and City parcels north of 7th Street Guide grading plans for future development adjacent to the corridor

Recommendations & Implementation: 

Recommendations & Implementation Adjustments North of CSAH 30 Location corridor separates from TH 25 on north Improves access options to downtown Shortens road length, reduces cost Shift to west Improves accessibility & use options for City property Severs 2.5 acres of Mayer Lutheran ball field parcel Avoids 7 acre unusable parcel in future residential area south of 7th Street Grading limits maintain most of existing trees on west edge of corridor south of 7th Street Avoids wetlands south of Dakota Trail, right–of–way mostly on land guided for industrial uses

Recommendations & Implementation: 

Implementation North of CSAH 30 Construction Staging Interim 2-lane road planned to be built in north bound lanes Built after right–of–way for corridor is obtained (primarily through development driven initiatives) Cost of interim construction – development driven funding sources, cooperative agreements, or other means available to City Cost participation of future 4–lane would be from multiple funding sources & shared between various agencies Recommendations & Implementation

Recommendations & Implementation: 

Implementation North of CSAH 30 (continued) City Responsibilities Lead efforts to preserve right–of–way, design & construct corridor Include corridor in future update to City Transportation Plan Lead studies for future roadway connections to downtown Mayer Ensure development in City is consistent with Study Require completion of environmental reviews as required by state or federal law Ensure stormwater management for 4–lane corridor is incorporated into subdivision design plans City jurisdiction of corridor until connection with TH 25 to the south Recommendations & Implementation

Recommendations & Implementation: 

Implementation North of CSAH 30 (continued) County & Mn/DOT Role Review & comment on development proposals (both) Review & approve corridor construction plans (County; Mn/DOT would do an administrative review) Consider change in jurisdiction when corridor is a continuous route between TH 7 and 82nd Street Recommendations & Implementation

Recommendations & Implementation: 

Recommendations & Implementation South of CSAH 30 Located outside of 2030 growth & expected to remain in a rural, undeveloped state If County receives development proposals for area, City & Mn/DOT review & comment Further study necessary by City, County & Mn/DOT prior to urbanization or including area in City’s urban growth boundary (recommended that A–2 not be pursued)
