<br />Engineers' Comments rkeview Quarry <br />Per Letter of Apri 1, 1979 • <br />Page 2. <br />"" Question (14--Comment Continued <br />correlation between limestone mined and the population of the City of <br />Colorado Springs. (See Tables in Attachment No. 1) Nevertheless, the estimates <br />are just that. <br />B. RECLAMATION PLAN <br />Question 111: How much topsoil will be replaced on each area to be revegetated <br />or, if no topsoil is to be used, what is the nature of the plant growth <br />medium to be used in place of topsoil? <br />Comment: 0" to 6" of additional topsoil as needed will be placed on all <br />areas to be revegetated. At the present, there are approximately 25,000 cubic <br />yards of useable soil particulates left on the site. This is enough "topsoil" <br />to cover only 40 acres of disturbed land. The remaining area (approximately <br />94 acres) will be covered with limestone fines capable of supporting plant <br />life. This material will be tested and fertilizers added, according to <br />recommended test results. In previous tests made in Queens Canyon Quarry <br />on limestone fines, the material normally was marginal in plant-available <br />phosphorus. Phosphorus will be broadcast before scarification of the <br />fines. In those areas of steep slopes,. phosphorus will be added after <br />grading. Limestone fines and spoils are usually nitrogen deficient. If <br />this is the case, milkvetch, a nitrogen-fixing legume will be added to the <br />seed mix. <br />Question 112: Where the various land uses of wildlife and industrial site <br />will be applied. <br />Comment: See Attachment No. 2 for Preliminary Site Development Drawing. <br />Question 113: In the area to be reclaimed as a wildlife area: <br />(a) How the area will be reclaimed as suitable wildlife habitat and <br />what wildlife the area will be designed to sustain. <br />(b) What type of revegetation is proposed including seed mixtures, <br />trees and shrubs, and how the growth medium will be supplemented <br />to establish the vegetation as quickly as possible. <br />(c) How the revegetation will be managed to protect it from detrimental <br />affects from grazing and particularly the detrimental influences of <br />excessive weed growth. <br />Comment: <br />(A) A Wildlife Statement prepared by the Wildlife Biologist previously <br />submitted to your office, states that there would be minimal negative <br />1 <br />
