River meanders have developed adjacent <br />to the railroad spur and future cutting will endanger the foundation of the railroad tracks. As a <br />result, bank stabilization will be conducted using rock veins (jetties) in the affected area. A design <br />package has been developed and is attached for your review and approval. This design package has <br />also been submitted the U.S. Army Corps of Engineers for approval through their General Permit <br />process. <br />A temporary access road and equipment laydown area will be used to facilitate construction of the <br />rock veins. These areas account for approximately 0.6 acres ofdisturbance which will be reclaimed <br />following construction. Since this is a limited area ofdisturbance with minimal impact for short <br />duration (only one week), no topsoil is proposed to be removed or salvaged. Reclamation will <br />consist of removal of all construction materials, grading any ruts or surface damage, and seeding <br />with the approved Pastureland Seed Mix. Total bond for the project has been calculated at $] ,000. <br />The rock veins are permanent structures and no associated bond has been calculated for these. <br />The attached page 2.05-13.1 of the Permit has been revised to reflect the inclusion of the design <br />package as Exhibit 2A. Also attached is a Technical Revision Form and a proposed public notice <br />for your review and approval. <br />5231 Sourh Qucbec Strecr • Greenwood Village, Colorado 801 I I <br />Phonc (303) 850-0930 • Faz (303j 721-9298 <br />Web Sire: www.greysrone-consuhanu.com • E-mail: greysioneC'grzystone-consuliams.com <br />
