Fort Collins, Colorado
ELI Project No. 20945154
Gentlemen:
We have received additional traffic data from the City of Fort Collins for the above -referenced
project. This letter serves as an addendum to our geotechnical report dated September 8, 1994.
The purpose of this addendum is to provide recommended pavement types and thicknesses for
acceleration and deceleration lanes along Skyway Drive, the south access road and the
deceleration lane along South College Avenue for the above -referenced project. The remaining
types and thicknesses for the remaining streets within the project area along with overall
recommendations for pavement subgrade preparation and pavement construction were addressed
in our geotechnical engineering report.
The following is a summary of the traffic data provided to us by Mr. Keith Meyer of the City of
Fort Collins:
