Note: The red line indicates where the approved 1,233 LF wall would be constructed. The green lines show the locations of where private funded walls could be constructed.
The location and approval of the noise wall was determined based upon the strict guidelines of MNDOT's noise barrier program. To meet these strict guidelines, there must be a certain density or number of homes that are located within close proximity to I-94. Although the approved wall does not cover the entire north side of Upper Spunk Lake, MNDOT has stated that private donations/funds can be used to add onto the west and the east side of the approved wall.
OPTION #2: The following is one scenerio (as shown in green on the above map) which is dependant on how much private funding can be raised: From the west side, if the wall starts near the rest stop on-ramp (east bound rest area on-ramp) and goes to about the billboard near the cemetery on the east side it is estimated to run an additional $3,639,288 or $67.3942 per square foot:
1,400 lineal feet to the east x 20’ high = $1,887,038 and 1,300 lineal feet to the west x 20’ high = $1,752,250
Total $3,639,288Total Project Cost Is:
$159,553 (private funds needed for the approved wall) + $3,639,288 (for expansion of the approved wall) = $3,798,841.
