<br />"'" <br /> <br />-.....I <br /> <br />City of Santa Ana Sewer Master Plan <br />Scope of Work <br /> <br />1. Research Existing Data and Records <br /> <br />1.1 Review existing 1993 Sewer Master Plan Update and Sewer Facilities Management <br />Program. <br /> <br />1.2 Interview up to 8 City staff to gain an understanding ofthe collection system facilities, <br />conditions, and problem areas related to high infiltration/inflow and lack of capacity. <br /> <br />1.3 Review the inventory of existing sewer videotapes and summarize the extent of the system <br />that has been inspected in recent years, and the general size and location of inspected <br />sewers. <br /> <br />1.4 Review SCADA records for run times at the two sewage lift stations. <br /> <br />1.5 Contact the Orange County Sanitation District and research availability of applicable <br />records and data. Coordinate data gathering efforts with OCSD, where feasible. <br /> <br />1.6 Meet with the City's Planning Department to obtain and review the most current General <br />Plan documents, digital map, Orange County Projections 2000 data for the City, and the <br />City's Year 2000 census data. Discuss with the planners topics including land use <br />classifications and densities, development and redevelopment areas, and areas which <br />deviate significantly in current use from the general plan. Also, obtain land use <br />information from neighboring cities which contribute wastewater to the City's sewers. <br /> <br />1.7 Meet with City staff to review and become familiar with representative sewer records <br />including sewer atlas sheets, Microstation design files, improvement plans, and record <br />construction drawings. Obtain the City's Microstation files containing all sewer main and <br />manholes, in which the City shall have flagged the approximately 1800 manholes and <br />associated pipe segments to be included in the model for this proj ecl. The associated <br />database tables to be provided by the City for these 1800 segments shall include manhole <br />and pipe identifiers and MS link numbers, and the upstream and downstream manholes for <br />each pipe. In addition, the lines representing the pipes in the graphic file shall be digitized <br />by the City in an upstream to downstream direction. Recommend any changes in the pipe <br />segments to be modeled that would improve the accuracy and completeness of the master <br />plan. City staff shall modify the Microstation graphic and database files to reflect those <br />changes that they approve. <br /> <br />2. Populate Database for Modeled Sewers <br /> <br />2.1 Review the existing sewer atlas maps (on which the City staff shall have indicated the <br />sewers to be analyzed in this master plan) to determine which microfilm aperture cards <br />contain the plans for modeled sewers. Obtain and scan the required cards, and replace the <br /> <br />CS 387 FORM: C:\DOCUME-l\cleeshawU.OCAlS.I\Temp'-AiTeement Paekni:c for(:itYAtt~_.tXH I B IT l1 <br />
