<br />Savage and Savage <br />Memorandum <br />To: Steve Faucher, Loveland Ready Mix Concrete, inc. <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: April 10, 2006 <br />Subject: Loveland Ready Mix Wash Fines Assessment <br />File #: M-1974069 <br />On March 6, 2006 we conducted an evaluation of the wash fines at the Loveland Ready <br />Mix site to assess their suitability as a "stand alone" plant growth medium. If the wash <br />fines were found to be suitable for revegetation, no additional topsoil replacement would <br />be necessary at this area of the site to ensure successful revegetation. <br />In the several locations we investigated, the texture of the wash fines was that of fine <br />sand, oRen referred to as "sugar sand". There was some clay and silt present in the <br />material we looked at; however the overall texture was very Sue. <br />In my experience at a mining reclamation site neaz Keenesburg, Colorado, wherever the <br />sugaz sand is present in large areas, revegetation is problematic without significant <br />addition of organic amendments to facilitate water holding capacity, increase av pore <br />space, and include additional organic material. <br />Therefore, in the areas where the backfill at the surface will be wash fines, I would <br />recommend application of topsoil over the wash fines. Four to six inches of topsoil <br />should be sufficient for growth of revegetation plant species. <br />In the last area we investigated, where backfill and the top regraded layer comprising the <br />final land surface contain more clay and silt, there appears to be an adequate mix of <br />textures and organic material to ensure vegetation growth. <br />
