<br />, <br /> <br />. <br /> <br />. <br /> <br />J ~'" <br />.' <br /> <br />PRASE III - TASK 4: PLAN OF DEVELOPMENT <br />cant. <br /> <br />KETBODOLOGY (cant.): <br /> <br />e. Analysis of water hammer in the pipelines and proposed method <br />of protecting the pipelines against water hammer pressures <br />will be identified. <br /> <br />f. The availability and source of construction materials will be <br />assessed. <br /> <br />2. Geologic Investigations <br /> <br />A feasibility-level geologic investigation will be prepared for <br />this project using existing published geologic information. A <br />site-specific geologic survey will be performed to a feasibility <br />level; this survey will be limited to field reconnaissance by a <br />CDM geologist and will identify surficial features and provide an <br />estimate of subsurface features. Detailed, comprehensive <br />geologic or geotechnical engineering reports are beyond the scope <br />of this study and will not be included in this report. <br /> <br />DELIVERABLES: <br /> <br />1. Structures - A description of the proposed major structures and <br />minor structures will be prepared which will include typical <br />sections of proposed embankments, profiles in sections of canals <br />and pipelines including dimensions, hydraulic properties, water <br />surface, and class of pipe for pipelines. <br /> <br />2. Drainage - A description of the anticipated drainage problems will <br />be assessed. However, since both locations are off-stream <br />reservoir sites with very small drainage basins, it is not <br />anticipated that extensive drainage protection will be required. <br />(This portion will be addressed in a conceptual level and be based <br />upon existing field conditions.) <br /> <br />3. Sedimentation - Based on the drainage study, a description of the <br />effect of suspended solids brought into the reservoir from surface <br />runoff will be assessed and the effect on long-term sedimentation <br />will be identified. In addition, the effect of suspended solids <br />on waters pumped from the Big Thompson River during the flood <br />stages will be estimated and the effect on basin sedimentation <br />will be addressed. <br /> <br />8 <br />
