Page 6 Pedro Guillen March 8, 2007 is not provided, physical system data will be required to build the model. It is assumed that the data is readily available and the district will assist with gathering the data. Flow Generation If the OCSD model is provided, M&E will review current (2005) and future model population, employment, and commercial flow inputs and update them where they do not match current and future conditions. Average and peak day dry weather flows, unit flow factors, and demand patterns will be established for current and future conditions based on the OCSD model and member agency data provided. Average and peak day wet weather flows will be based on the OCSD model or other master plan data. M&E will develop flow scenarios to match current conditions without the proposed project, current conditions with the proposed project; 2010 conditions with the proposed project; and 2030/Buildout conditions with the proposed project. Model Build If the OCSD model is provided, this task is considerably easier and only involves determining the model extent necessary. If no OCSD model is provided, this task involves building a model with pipes, manholes, and sewersheds that cover the member agency and OCSD sewers based on the determined model extent. Capacity Evaluation M&E will perform capacity simulations with the updated Info. Works model for the following 4-6 main scenarios (a total of 8-10 with wet weather runs): • Current conditions without proposed City Place Sky Lofts development (2006-2007). Current conditions with proposed City Place Sky Lofts development (2006-2007). • Future conditions without proposed City Place Sky Lofts development (2010, and possibly 2030). • Future conditions with proposed City Place Sky Lofts development (2010, and possibly 2030). Present EIR Impact A full analysis of the impacts to the OCSD and member agency sewers will be performed. The results of the analysis will be conveyed with text, tables, graphs, figures, and maps. The deliverable of this task will be a memorandum or short report. It should be noted that if assumptions above hold true, it is anticipated that the study can be completed within 30 to 45 calendar days from the notice to proceed. If assumptions do not hold true, M&E anticipates the study will require 45 to 60 days to complete. Water Assessment (Not Included) A water assessment is not included in the scope of work, as P&D's review of Senate Bill (SB) 221 and SB 610 indicates that they would not apply to the Sky Lofts Project. Shade -Shadow Analysis P&D will conduct a shade -shadow analysis of the Sky Lofts Project building. Figures will be prepared with computer software that will show the shadow patterns cast by the building during summer and
