i Cooley Gravel Company has undertaken a unique experimental reclamation program at its Morrison Quarry site. The program is "experimental" because very little has been done in the past to reclaim quarry sites in the semi-arid Colorado Front Range environment. Therefore, little, if any, past experience can be drawn upon in an undertaking of this mag- nitude. In our efforts, Cooley Gravel Company hopes to establish a role model for Quarry Reclamation in this area. The important features of this program include: 1. Utilization of indigenous species to avoid introduc- tion of foreign, competing species of vegetation. 2. As much as possible, planting in patterns which simu- late naturally occurring vegetation on surrounding lands. 3. Variation of heights of plants and backfilling levels, along with planting of vines to break up the horizon- tal high walls. 4. A recognition that plantings that are too dense would create a high die-off rate and a need for a tremendous amount of irrigation. 5. Rock faces occur naturally and an attempt to cover all rock areas would result in an unnatural pattern of vegetative cover. 6. A need for plantings to become independent of artifi- cial irrigation over a period of time so they can thrive on natural water supplies, and finally; 7. Our Contractor, Skelley and Loy, will maintain the plantings for a two-year period and guarantee a suc- cess rate of 85% of all plantings under this program. This experimental program will be utilized as our basis for further reclamation work at the quarry. Exhibit #1 shows the aerial limits of this experimental reclamation program with the general planting pattern and a con- ceptual drawing of the mature plantings. Exhibit #3 shows the bench detail and lists plantings being utilized, 1700 plantings in all. The vine detail is not shown simply because of the difficulty in graphically displaying this feature. -6-
