<br />Structure Description/notes Owner
<br />Culverts and pipes 4 culverts under Highway 145; 1 under entry road, no CDOT
<br />impact anticipated. 1 pipeline, approximately 700 feet long,
<br />for drainage of field into river (irrigation return flows) Landowner
<br />Evaluation The culverts vary from 24 to 36 inch diameter, corrugated metal pipe, in fair to poor
<br />condition, with sediment and damage from mowing or other activities. All culverts
<br />drain water from the west side of the highway to the east side, where Flows enter the
<br />Home Ditch. The culverts are no closer than 50 f8et from the nearest mining
<br />operations and disturbance, and because the culverts are uphill from the mining
<br />area, there will be no impact on stability or function of the culverts.
<br />The 700-foot pipeline drains return flows and storm water from the irrigated cropland
<br />to be mined, and has been incorporated into the storm water management plan for
<br />the mining operations. The inlet for the pipe is at the southeast corner of the pit and
<br />will be modified during mining to accept discharge of storm water and any
<br />dewatering flows from the mining pit. Therefore, there will be no damage to the
<br />structure from mining activities except as expected for normal wear and tear from its
<br />operation for its intended purpose.
<br />Structure Descriptionlnotes Owner
<br />Buildings Line Camp ranch headquarters and riding area: consisting Landowner
<br />of various structures including barns, sheds, residence,
<br />fences, corrals, wells, etc.
<br />Evaluation The Line Camp ranchstead is located approximately 250 feet from the permit
<br />boundary and therefore from the proposed affected land, and the riding area is
<br />approximately 800 feet from the permit boundary. However, these are included in
<br />this evaluation as being representative of the nearest occupied buildings to the
<br />proposed mining operation. These structures are located on the same alluvial
<br />formation and soils as the proposed mining operation, and at a slightly higher
<br />elevation, being upstream along the river. The structures are on the edge and
<br />partially within a large wooded area of tall cottonwoods on the valley floor, and vary
<br />in age and condition.
<br />Based on the soil, ground water conditions, terrain, planned mining operations and
<br />activities associated with the mining, and offer inspection of other similar situations
<br />in the general area, there is no expectation that any of the structures will be
<br />damaged by activities occurring at the mining operation.
<br />Soils: The soils on which the various permanent.structures and the mining area itself are located range in
<br />texture from sandy loam to silty loam, are about two feet thick, and underlain by sand, gravel, and
<br />cobbles. East of the highway, the land slopes at about 1 percent from west to east. The highway and
<br />Luntz road are built on engineered fill (a railroad embankment) taken from borrow pits to the west, and still
<br />in the flood plain or at the very base of the valley wall. The soils have a low shrink-swell potential and very
<br />low potential for mass movement.
<br />This evaluation was prepared based on information obtained from the owners, including Empire Electric,
<br />Century Telephone, Colorado DOT, and Duvall Truelsen, from various agencies, including USDA Natural
<br />Resources Conservation Service, US Forest Service, and Dolores Soil Conservation District, and during
<br />site inspections and investigations conducted in August, September, and November, 200Q,,.~n ~~~_,,,,
