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.
Please call me at 651.490.2147 if you have any questions.
