<br />Geoteehnical Assessment of Construction Activities for Amendment of Permit <br />• Proposed Brighton Water Storage Project, Adams County, Colorado <br />Job No. 03-1076 <br />Page 2 of 2 <br />the pond slopes. Therefore, so long as existing slope angles are maintained or <br />flattened, we do not anticipate development of failures that would adversely affect <br />existing structures. We understand that Les Ewegen, LLC, has committed to repair any <br />slope failures (likely to be surficial) that may develop and make other necessary repairs. <br />Therefore, in GROUND's opinion, the likelihood of structures being adversely affected by <br />the proposed pond deepening is low. <br />We understand that the plans for proposed bridge to span Fulton Ditch near 120' <br />Avenue are being reviewed by an engineer for Fulton Ditch. GROUND understands that <br />the ditch embankments are on the order of 5 to 6 feet in height. We also understand <br />that present plans call for the footings at the bridge abutments to be 6 or more feet from <br />the edge of the ditch. We anticipate that the footings will be set 3 or more feet below <br />existing grades. Therefore, we do not anticipate adverse affects on the ditch <br />embankments from installation of the proposed bridge, based on geotechnical <br />considerations. We recommend, however, that temporary excavations and foundation <br />backfilling near the ditch be done when the ditch is empty. <br />GROUND further understands that truck traffic along the existing temporary access road <br />traversing the parcel south of the Brighton Water Storage Project will continue in a <br />manner similar to current usage. Therefore, although there are a barn and asingle- <br />family residence within the 200-foot radius of interest of that road, other than nuisance <br />noise and vibration, we do not anticipate That distress to the structures or their <br />foundations will develop from this continuing truck traffic, based on observation of <br />existing conditions. <br />We trust that this provides the information that you needed at this time.
