}AM1 v <br />Storm Drain Master Plan <br />Phase 2 RFP No. 16-02 x <br />cope of Work <br />Based on the City's requests in the RFP and our experience with similar projects, we recommend the <br />following scope of work: <br />TASK 1 — Review and Research <br />Task 1.1 Review Phase 1 City Storm Drain Master Plan (2015 SDMP) <br />Michael Baker will review the City of Santa Ana Storm Drain Master Plan (2015 SDMP). Data review will <br />include location of known flooded areas, design criteria, hydrology methodology, hydraulic analysis, and <br />prioritization criteria. This task can be completed efficiently since the Michael Baker staff are familiar with <br />the watershed, methodology and constraints within the City of Santa Ana local and regional drainage <br />systems. <br />Task 1.2 Review of Facilities <br />Michael Baker will perform a qualitative review of the priority proposed storm drain system from the 2015 <br />SDMP and identify locations for alternative drainage improvements. This task will require an above- <br />ground field assessment and inspection of existing City owned facilities (parks, City owned vacant lands, <br />schools if desired, etc.). This inventory will include drainage facilities (storm drain lines and channel) <br />throughout the City. <br />Michael Baker will work directly with the City to identify and re-evaluate the priority improvement projects <br />previously identified in the 2015 SDMP. The investigation will identify locations for potential LID flood <br />storage improvements facilities. The collected data will be mapped using GIS and provided to the City. <br />To facilitate the inspection process, Michael Baker will coordinate with the City and the local communities <br />impacted by the field review prior to performing the work. Coordination may include notifying residents <br />and providing educational information about the value of data being collected. <br />A memo summarizing the 2015 SDMP methodology and guidelines will be prepared for City review. This <br />document will serve as an initial reference framework for future decisions as work progresses and unique <br />opportunities are encountered for flood reduction. <br />Deliverables: <br />1. Inventory Log of All Data Collected <br />2. Technical Memo highlighting potential projects and alternative solutions <br />TASK 2A— Alternative Improvements Expected Value Conversion <br />Task 2A.1 2015 SDMP Proposed Facility Evaluation <br />Michael Baker will re-evaluate the proposed drainage systems identified in the 2015 SDMP including the <br />recommended improvements list and develop a table highlighting the construction constraints and cost - <br />to -benefit comparison for each project. Construction constraints will be a high-level analysis based on <br />the available utility data provided by the City and street classifications. <br />Project benefits will be valued based on locations of flooding history and theoretical estimation from the <br />hydraulic modeling based on the tributary drainage area to each system. A tabulated matrix will be <br />provided that summarizes this task. <br />Page 1 9 <br />INTERNATIONAL <br />
