Emergency Loan Application and Feasibility Study CHURCH DITCH WATER AUTHORITY <br /> Alternative 2—Rebuilding Collaboratively with Improvements: The Church Ditch Leyden Creek <br /> crossing is located in unincorporated Jefferson County in planned open space. The area is void <br /> of development, trails, roads, sidewalks and is only accessed from the Church Ditch access road. <br /> Major structures upstream and downstream of the crossing include: Quaker Street('/a mile <br /> upstream)and Leyden Reservoir('h mile downstream). In conversations with City of Arvada <br /> personnel on September 27th, it is our understanding, that these structures have received <br /> emergency/minor repairs with no major repairs projected. The other smaller areas of damaged <br /> are limited to the Church Ditch and have no effect on outside agencies. Collaborative on this <br /> project appears to be highly limited. <br /> Selected Alternative 3 — [Church Ditch Flood Repairs]: The project entails restoring the Church <br /> Ditch to pre flooding conditions. Plans for the Leyden Creek Crossing call for the placement of <br /> fill to rebuild the embankment and access road. The section of Church Ditch that experienced <br /> the washout will be piped to prevent the uncontrolled diversion of flood waters in potential <br /> future events. For all areas, sediment that was deposited by the flooding will be removed and <br /> the ditch banks reshaped where sloughing has occurred. Additional, riprap will be added to <br /> some of the reconstructed portions of the ditch to prevent erosion and increase protection to the <br /> ditch. The proposed solution provides for the most cost effectiveness that can be completed in <br /> the available construction schedule to restore water supply deliveries with the less amounts of <br /> disruption and risk to Church Ditch operations. <br /> Cost Estimate <br /> The Project cost estimate, provided by Ecological Resource Consultants, Inc., is $443,560 and is <br /> further broken down as follows: EXHIBIT F <br />
