2015/08/05 Council Agenda Packet

MSA's Project Manager will develop and distribute a detailed meeting agenda before the meeting and minutes after the meeting 2.3 Sulo -Basins and Projected Flow Volumes — Delineate the sub -basins that have the potential to drain to the golf course, including the area defined by the Northwest Storinwater Separation Improvements. Based on these sub -basins and using the WWFIM model, define the stormwater volumes that can be conveyed to the golf course based on the City's selected design storin conditions. 2.4 Development of Concepts — Develop concepts to manager stormwater within the golf course considering detention, irrigation use and/or utilization of existing outfall. Define pond volumes and potential locations, existing outfall capacity, irrigation rates, transfer pump and piping requirements and control structures. Concepts shall accommodate phasing of improvements with the implementation of Northwest Stoirawater Separation Improvements as the first phase. 2.5 Workshop — Meet with City staff, Public Works and Parks, to review and discuss concepts, establish criteria that should be considered in the evaluation of concepts and define up to three alternatives that should be carried forward for further more detailed evaluation. This workshop will also review the division of responsibility between Public Works and Parks for the cost and operation of proposed facilities. 2.6 Evaluation of Alternatives — Alternative concepts defined in the previous subtask will be fiarther defined to characterize their advantages/disadvantages, develop preliminary opinions of cost and quantify their overall effectiveness in managing stormwater based on criteria established. Alternatives will be evaluated based on the criteria established in the previous subtask. 2.7 Preferred Alternative Workshop — Prepare for and conduct a workshop with City staff, Public Works and Parks, to review and discuss alternatives. During this workshop alternatives will be reviewed taking into consideration the characteristic of each alternative and established criteria. Through this process a preferred alternative and recommendation for the management of stormwater in the golf course will be identified. 2.8 Documentation — Work under this subtask will included documentation of the work performed under this task and definition of the preferred alternative in a technical memorandum. The technical memorandum will define potential phases, with Phase 1 being the Northwest Stormwater Separation project. It is anticipated that this document could be used as the basis of a Memorandum of Understanding between Public Works and Parks on how stormwater will be conveyed to and managed at the golf course. -1 .r iron.. 19 r,�T3 L7 AV ,,,7ITW 1.
