2005-08-15 Pedestrian Trail Construction Jt.. SEH MEMORANDUM ~~ 'I o~~ (~:t:~ . <:'~l>: I (J<lltlf ~.() TO: Larry Kruse Albertville City Administrator Arv'Robert Moberg, PE Project Manager FROM: DATE: August 15, 2005 RE: Albertville, Minnesota Albert Villas 6th Addition Pedestrian Trail Construction SEH No. A-ALBEV0212.00 14.00 At your request, SEH has analyzed the cost of installing a bituminous trail along the west side of Swamp Lake. As you are aware, Edina Development proposed to install the trail as part of Albert Villas 6th Addition. To date, the trail has not been constructed, primarily because of poor soil conditions along Swamp Lake. We evaluated three options for constructing the trail: 1. Installation of the trail at the original location shown on the development plans. Installation would include construction of a bituminous trail to current City standards but would not include any soil correction work. Cost of construction is estimated to be $23,500. This option is the least expensive but would also result in a greater risk for the City, because the facility would have a high cost of ongoing maintenance and would not likely have a significant service life. 2. Installation of the trail at the original location shown on the development plans and provide for soil correction. Soil correction would include a 3-foot subcut, installation of geotextile fabric, placement of 3 feet of select granular borrow, and installation of a reinforced geogrid to stabilize the trail in the poor soils. Cost of construction is estimated to be $91,000. 3. Construction of a boardwalk through the area of poor soils. For this option, approximately 1500 feet of boardwalk would be installed. Total cost of construction is estimated to be $381,100. If the City desires to pursue any of these options, we recommend a thorough geotechnical investigation first be conducted to determine the extent of soil correction needed.
