My name is Terry Podmore and I live at 733 Gilgalad Way in Fort Collins. I am a member of the Windtrail on Spring Creek Homeowners Association and a Professor Emeritus in Civil and Environmental Engineering at Colorado State University. My purpose this evening is to address the problem of the Larimer #2 Canal and its potential impact if the proposed Campus Crest development takes place. The placement of buildings close to the canal on the south side of the site creates the risk of a canal breach from increased seepage leading to catastrophic failure. It has been proposed that the canal be moved to the south to avoid this danger. However, the canal relocation does not appear in the ODP and is only referenced in the PDP. The City Manager, Darin Atterberry, has stated that the canal relocation is unrelated to the Campus Crest project.

Linda Ripley stated at. the neighborhood meeting held on May 23`d that there was no guarantee that the canal relocation would take place prior to the construction of the Campus Crest project. Therefore, the impact of the Campus Crest construction must include consideration of a possible canal breach. The canal company has stated that it takes 12 hours to stop the flow of the canal by closing a control gate at the Poudre River. The canal length from the Poudre River to Shields Street is approximately 8.2 miles. With a typical cross section of 100 square feet, the canal volume is 4.32 million cubic feet or 32.3 million gallons. In the case of a canal breach, this water would be released on to the site. This volume of water assumes that the canal flow can be shut off instantaneously if a breach occurs. In case of any delay, the canal would keep on flowing and releasing water. A typical canal flow was given as 150 cubic feet per second by John Moen, the manager of the canal company. Consequently, for every hour of delay before
