<br />1 <br />PROPOSED CHANGES 12 <br />-~ Environment <br />_.,q Air pollution will not be increased significantly by WPC's proposed <br />'~ gravel mining operations on the Weng farm. Sand and gravel will either be <br />removed from the site, by railroad or truck, or stockpiled at the site. <br />Dust resulting from crushing operations is expected to be minimal, because <br />the material is wet and because about 90% of the material will be chipped <br />pitrun from the site. Noise from the crushing operation will not t>e loud <br />fj enough to bother residents living near the site. There will not be any high- <br />rise construction by WPC that might impair the mountain view of other prop- <br />erty owners. <br />WPC's graphic plan for site reclamation, following completion ~f its <br />gravel mining operations, is available for inspection at meetings and dis- <br />cussions. It consists of a constant level lake, with sandy beaches and land- <br />scaped grounds, which will be in harmony with the character of the surround- <br />ing neighborhood. Following WPC's proposed reclamation, the appearance of <br />the site will be much better than it is at the presenC time. The value of <br />adjoining property is expected to be substantially enhanced, in about 15 <br />years, by Che changes which WPC plans to make on the Weng farm. <br />St. Vrain Greelc. The site development plan, Exhibit 4, indicatt:s that <br />' WPC plans to leave a natural berm, 20 feet or more in width, around the <br />periphery of its gravel mining operations. Earth fill will be placed in a <br />low section of the flood plain of St. Vrain Creek, as shown on Exhibit 4. <br />In addition, the south bank of the normal channel of St. Vrain Creek gill <br />be strengthened by construction of two rock revetments, each about 60~) feet <br />) <br />in length (Exhibit 4). <br />If St. Vrain Creek overflows its embankments, water may flow into, WPC's <br />excavated areas on the Weng farm site, south of the creek. The natural <br />drainage at the present time (Exhibit 2), is from northwest to southeast. <br />The drainage pattern after site development (Exhibit 4), will likewise be <br />
