We appreciate the opportunity to review this submittal as it relates to the South <br />Bill Himmelmann Platte River. <br />City of Denver rn <br />o <br />B. H. Honmaster <br />Engineer ,°, <br />® <br />We have the following concerns and comments: <br />Carolyn McIntosh ° <br />City of Lafayette <br />F <br />1. The applicant has stated that no mining will occur within 400 feet of the South <br />idel Montoya ~ <br />cry of Denver Platte River channel without approval by the Urban Drainage and Flood Control <br />Lintla Morton <br />City of Lakewood <br />~ District (District .

The plan needs to be revised accordingly before <br />Art Panen approval, I have enclosed a sketch of the 100- to 400-feet we feel is acceptable <br />Engineer <br />~ <br />now. This is especially important along the west bank of the river at the McKay <br />Richartl Sheehan <br />Jenarson County ; Road and 104th Avenue bridges. Preliminary plans call for new longer bridges. <br />James Sulbvan <br />Douglas County g <br />z Therefore the mining and reclamation setbacks need to start from the master <br />~ <br />Elaine Valente ° plan channel bank alignment (i.e., proposed west side bridge abutments), not the <br />Adams County ; <br />w 100-foot minimum setback 8S shown on Exhibit C-2. <br /> 2. On Exhibit C-2, IvIining Plan Map, the Phase lA and 1B areas show a note that <br /> reads "no mining within 35' of the top bank S. Platte River." The minimum <br /> setback allowed is 100 feet with both riverbank and pitside bank protection. A <br /> variance maybe allowed if the applicant can guarantee that they mine and <br /> immediately reclaim the area within the 100-foot setback during one low flow <br /> season (generally October through March). <br />plaoWrymtnrormt <br />
