RE: Glacier Meadows Subdivision
Kalispell, Montana
Subject: Letter Dated March 28, 2003
Dear Mr. Schwarz:
Based on the subject letter we request the following items in order to continue the approval
process for the referenced project:
1. Test data that verifies the existing sub -base and base material meet the requirements
shown on City of Kalispell Design Standard Drawing No. 3 must be submitted. The total
asphalt thickness should be at least 4".
2. The transverse slope of the pavement must be two per cent.
3. Washed gravel, or any other material is not to be used for fill in open drainage ditches.
The open ditches should be re -vegetated with sod only.
4. A plan -profile sheet for 'upgraded' Granrud Drive must be submitted. In addition, the
plan -profile sheet should contain the drainage details for the Granrud Drive - Granite
Lane intersection, and Granrud Drive - Buffalo Stage intersection.
Finally, one last point must be made. Note No. 1 of the City of Kalispell Design Standard
Drawing No. 3 (copy attached) states in part "This cross-section must be approved by the City
Council prior to incorporating into the drawings." The City Council's approval of this project
was based upon a standard level for upgrading Granrud Drive. Although we have no
disagreement in principle with the proposal submitted, it reflects a deviation from the concept
that was initially approved by the City Council and therefore it must receive City Council
approval prior to use.
