<br /> <br />Mr. Mark A. Heffner - 2 - May 6, 1985 <br />b. Columbine Industrial, Inc., the owners of the land across which <br />the relocated ditch will traverse prior to entering the permit <br />boundary, concerning use of their land, and compensatory <br />measures proposed if property damage occurs. <br />3. Please provide the agreement between Castle Concrete Company and <br />the Colorado Division of Highways concerning the proposed "boring" <br />24 feet beneath Academy Boulevard. <br />Amendment approval will be contingent upon receipt of this <br />document; the amendment is meaningless without realization of this <br />agreement. <br />~ 4. You stated the access road relocation further south of its present <br />location will be accomplished by backfilling the north bank below <br />the roadway. It seems backfilling the south slope of the roadway <br />would facilitate the road relocation further south. Please clarify. <br />5. What is the proposed final depth of excavation? The original plan <br />and Technical Revision #2 totaled an excavation depth of [95' <br />(sand) + 15' (gravel) removal] 110 feet.l <br />6. As noted in Mike Stanton's June 9, 1982 Inspection Report, steep <br />high•.alls were present on site. His suggestion of mining in <br />benches to promote stability, and facilitate reclamation <br />(backfilling) is reiterated. Please respond. <br />Exhibit E -Reclamation Plan <br />1. If the site is not reclaimed for commercial <br />~ commit to smoothly grading the 8 to 12 feet <br />simulate "continuous yet undulating" natura <br />slopes be planar or undulating? <br />2. Will the slopes of the ditch be revegetated <br />development, please <br />"stair-step pattern" to <br />topography. Will the <br />for stabilization? <br />3. Will the access roads (present and potential) be reclaimed? <br />4. Please discuss the drainage of the resulting "very gradually <br />sloping platform extending about one-half mile from the back of the <br />Sand Pit southward to Bradley Road". More than 100 acres from the <br />combined Sand Pit and Daniels Sand Pit No.2 areas comprise the <br />newly developed "drainage basin". "Channel" or "swale" <br />construction on site would aid in directing overland flow, thereby <br />reducing the erosion potential. <br />5. What is the proposed method of planting? <br />6. Please discuss the possibility of creating "plant growth media" by <br />incorporating excavated clay lenses, manure, mulch, and chemical <br />fertilizers to the fines planned to be utilized as "top-dressing". <br />
