GEOTECHNICAL ENGINEERING REPORT 7erracon
SLAB CANYON QUARRY RECLAMATION
LARIMER COUNTY, COLORADO
ELI PROJECT N0. 20945006
1 FEBRUARY 2, 1994
1 INTRODUCTION
This report contains the results of our geotechnical engineering exploration for the proposed
1 reclamation of Holnam, Inc.'s Slab Canyon Quarry located approximately 20 miles northwest of
Fort Collins, Colorado. The site is located in the Section 26, Township 1 1 North, Range 70 West
of the 6th Principal Meridian.
The purpose of these services is to provide information and geotechnical engineering
recommendations relative to:
• subsurface soil and bedrock conditions
J • groundwater conditions
J • embankment evaluation
• earthwork
The conclusions and recommendations contained in this report are based upon the results of field
J observations and laboratory testing, engineering analyses, and experience with similar soil and
slope conditions.
J PROPOSED CONSTRUCTION
] The project as we understand it is to construct load-out benches which will be approximately 60
feet wide and 15 feet high. The benches will be constructed on approximately 1 %.:1 slopes. The
load-out benches will be constructed with overburden sandstone material remove~j during the
quarrying process to obtain the limestone below. The dip slope on which these benches are to
be constructed is approximately 12 degrees to the east. The top of the load-out ben~;h will grade
a minimum of 2 feet to the uphill end of the slope. The load-out benches will be seeded with
vegetation and used for drainage and erosion control.
SITE EXPLORATION
The scope of the services performed for this project included site reconnaissance by a senior
engineering geologist, a field sampling program, laboratory testing and engineering analyses.
