Loveland Lake and Ditch Company Updated March 20, 2008 Page 3 of 5 Agenda Item 18a Project Description The purpose of this project is to enhance the means for the Company to continue providing irrigation water to shareholders by increasing the inlet capacity to take advantage of storage opportunities as the Reservoir comes into priority. Five alternatives were considered: 1. The no-action alternative. 2. Reinstate the ravine as the inlet for the Reservoir. 3. Abandon the old easement in favor of a new easement that follows the path of the ravine, which is a shorter path to the Reservoir by nearly halfthe distance. 4. Replace the existing pipe with a larger pipe. 5. Install a pipe parallel to the existing pipe. Alternative No.1 - No action was considered unacceptable since the Company could not reasonably be expected to store the amount of water needed to deliver water to its shareholders, given the restrictive rate ofthe existing inlet and the relatively short window in which the Reservoir is typically in priority during the year. Alternative No. 2- Reinstating the ravine as the inlet was ruled out because of the potential for continued and exorbitant expenses related to cleaning up the trash that have accumulated in the ravine over decades of unrestricted and unsanctioned dumping into the ravine. Alternative No.3 - Following a shorter path with an easement through the ravine was ruled out due to the resistance of the property owner to allow the location of the right of way to be moved. Alternative No. 4- Replacing the existing inlet pipe was ruled out due to the expense of removing the existing structures on top of the expense of installing a new line. Alternative No. 5 - Installing a new pipe parallel to the existing line was selected since it was the least expensive option to achieve the goal of increasing inlet capacity and was acceptable to the Company. The selected alternative, Alternative No.5, involves installation of a larger, 30 inch pipe parallel to the existing pipe along with the supporting gate structure and flume. The new 30 inch pipe will be able to deliver 50 cfs. The existing pipe will be left in place so that both may be operated concurrently if the opportunity arises. In addition to the 30 inch pipe, a new headgate off the Handy Ditch to open into the new line, and a new flume capable of measuring up to 50 cfs will be installed. Additionally, repair work will be done on the outfall structure where erosion has caused damage. Loonan & Associates, Inc. has prepared engineering designs and cost estimates for the project. Construction began in February 2008. If construction is completed as scheduled, the new pipe line should be operational by May 2008.
