United States Soil 15 Wilcox Street <br />Department of Conservation Castle Rock, CO 80104 <br />Agriculture Service (303) 688-342 <br />March 3, 1989 RECEIVED <br />' Ron Allingham MAR s~~ <br />Tuttle Applegate Rindahl, Inc, <br />11990 Grant Street, Suite 410 <br />Denver, CO 80233 <br />' Dear Ron: <br />Enclosed are the vegetative inventories and seeding recommendations for <br />the Hallett Materials project on the Winkler property in Douglas County. <br />On February 27, 1989, Mike Applegate provided access for me to actually <br />' visit the site. At that time it was difficult to see the total <br />vegetative composition, since the grass had been quite heavily grazed. <br />The attached inventory covers the major species; I am sure there are <br />others which were not apparent, due also to the time of year. <br />' If possible, I would like to do another inventory in June, when the <br />grass is actively growing. The list of plants would probably be <br />expanded at that time, although it would be unlikely that it would <br />result in a change in the seeding recommendation. <br />' The seed mix is based on what was observed, what should be there and on <br />what will grow reasonably well et this location. All the grasses are <br />native species. The recommended time of seeding is from October 15 to <br />May 1, as long as the ground is not frozen. If a 20 acre parcel is <br />' completed end ready for reseeding outside these dates, a cover crop of <br />oats, sorghum or Sudan grass should be considered, to provide temporary <br />erosion control until the grass can be planted. <br />' Topsoil should be stockpiled and stabilized, unless it will be <br />stockpiled less than three months. Stabilization may be accomplished by <br />mulching, erosion control fabrics, or temporary seedings. <br />' Also enclosed are the Soil Conservation Service Standards end <br />Specifications for the practices of Critical Area Planting, Mulching and <br />' Cover Crop. We recommend these items be included in the reclamation <br />plan. <br />If yeu have any questions, or need more information, please feel free to <br />call. <br />Sincerely, <br />i j~~.c ~~~y? ce-~.,, <br />curie B.
