Spearfish recommends Route 2 for Exit 8 rec path connection

February 22, 2019

SPEARFISH — The Spearfish City Council Tuesday recommended Route 2 as its preference to connect the city’s shared use rec path system to the Exit 8 area.

Tonya Vig, city floodplain administrator/engineering tech, provided a presentation about the route options, their design constraints, and components. She explained that Route 2, approximately 2 miles total, travels from College Lane, along Mortensen Drive, through Spearfish Pellet Company, LLC, property to Hillsview Road, starting on the south side and then crossing to the north side, to the east side of McGuigan Road, cutting further east to either utilize the west side Clear Spring Road, eliminating the current parking, for bicycle traffic and the sidewalk on the west side of the road for pedestrian traffic to Tumbleweed Trail, utilizing the existing Higgins Gulch crossing at Tumbleweed Trail, then continuing along the east side of McGuigan Road to Exit 8, then along Old Belle Road to Russell Street.

City staff and the parks, recreation, and forestry advisory board recommended that option, made with asphalt surface, due to its budget, constructability, connectivity to multiple subdivisions in the Exit 8 area, obtainable easements from private landowners, and safety matters, Vig described.

The council unanimously recommended route 2 with asphalt surface.

“I think what we’re after, I think it serves two purposes, really, the main ones we were looking for, and that is connectivity of all those subdivisions and secondly, safety on McGuigan Road, I think, is really important, so I would definitely approve with what was said,” Councilman Dan Hodgs said.

“Thanks for your work,” Mayor Dana Boke added.

The cost estimate to build Route 2 with asphalt concrete pavement is approximately $1.34 million. The estimate includes an approximate consultant design fee of $200,000 for design and construction administration fees, as well as a 20 percent contingency. The estimate does not include land acquisition costs.

The city has $1.375 million in its five-year capital plan for the final design and construction of the project, and remaining funding could come from diverted funds, grants, or private/public partnerships, Vig said.

The other route option presented, about 1.5 miles in length, showed a connection from the existing sidewalk on Evans Lane to Old Highway 14, cutting to the east of the Cavalry Assembly of God church to Interstate 90, to Exit 8, then along Old Belle Road to Russell Street.

The full report is available at cityofspearfish.com/Engineering/Conceptual%20Design%20Report%202-8-2019.pdf and outlines key considerations, feasibility, and construction components for the route options.

The city first considered the route options in December, and since then, the Lawrence County Commission and other stakeholders weighed in on the options, as the routes crossed through various jurisdictions and rights-of-ways. County officials voiced concerns about building the pathway near the bottom of the highway ditch, concerning Route 1, as the path was proposed in the Old Highway 14 right-of-way. The state Department of Transportation also noted multiple concerns of the proposed Route 1 section within Interstate 90’s right-of-way.

The approximate width of easements for the proposed path is 28 feet, allowing for a 10-foot clearance on either side of the 8-foot path. The Route 2 alignment requires agreements with Spearfish Pellet Company, LLC, and Spearfish Forest Products, Inc.; a maintenance liability agreement with Lawrence County for portions of the pathway proposed within county right-of-way. Temporary easements for grading along McGuigan Road may also be required. Access easements would also be necessary for the route through property owned by Spring Creek Ranch, Butte Electric, and Ron Harris.

Vig explained that staff would continue to work with the various owners and agencies during the final route design to obtain construction easements, permanent easement agreements, and hold harmless agreements as required.

There are design guidelines, including a maximum cross slope of 2 percent and maximum grade of 5 percent, with the exception of short distances, and various locations along the route would require fencing. Floodplain considerations are also being made, with some locations requiring small culverts or culvert extensions to allow for drainage to cross under the path, as well as regrading.

Vig explained that the preliminary schedule moving forward is to have phase 1 of the final design completed and bid in fall 2019, with construction to start in the fall, with the goal of completing phase 1 construction in early fall 2020. Phase 2 design would be completed and bid in December 202, with construction expected to start in the spring of 2021, with completion at the end of 2021.
