Specifically, completion of a Drainage Report, Geotechnical Pavement Design Memorandum, and Water Quality Management Plan (WQMP), Right of Way (ROW) Engineering, Utility Coordination, additional Storm Drain Design, Utility Potholing, and contract administration are all additional tasks necessary to advance the Project through the 90 percent and 100 percent Plans, Specifications and Estimates (PS&E) milestones.
D. Consultant is uniquely qualified to perform these additional services because of its familiarity with the Project, existing engineering analyses, community outreach, and ongoing design efforts. Utilizing Consultant to complete the additional work will maintain project continuity, avoid duplication of effort, and minimize schedule impacts.
E. Pursuant to Santa Ana Municipal Code Section 2-807, City staff coordinated with the Purchasing Manager in regards to the additional work contemplated by the Consultant.
The Purchasing Manager approved the exception to process for bid requirements consistent with City code and the procurement process established under the RFP.

Preparation of a Water Quality Management Plan (WQMP), including stormwater treatment calculations, Best Management Practice (BMP) design, preparation of technical specifications, regulatory documentation, and completion of Orange County recordation requirements (Exhibit A-3).
d. Preparation of Right-of-Way (ROW) Engineering, including fifteen (15) title reports to support new roadway easements, five (5) additional title reports to support intersection curb returns where the documented ROW does not match existing improvements, performing ROW engineering to verify existing parcel boundaries for affected parcels, preparation of Plats and Legal descriptions to support 15 new parcel takes, and address comments.
HDR will begin utility coordination with Southern California Edison (SCE). The coordination effort will include the preparation of utility impact exhibits specific to SCE facilities in order to facilitate relocation coordination with SCE and other utility owners.
Two (2) additional drainage systems are required by PWA for inclusion into the design package. These two systems will replace deficient systems located at the Main Street and Broadway Street intersections. The HDR design team will prepare new plans and profile design plans for these two drainage systems and include the plans in their 90% and 100% design submittals. This task will include plans, specifications and cost estimates for the added drainage items and will be incorporated into the drainage report with supporting hydraulic calculations.
Utility Potholes: The HDR team will complete 35 utility potholes to locate existing utilities at critical points along the corridor including proposed utility crossing and traffic signal locations. The utility pothole information will be supplied to the PWA in the form of a field report and the pothole data will be added to the First Street utility plans. (Exhibit A-4).
2. SECTION 2.a, COMPENSATION, is hereby amended to increase the total compensation by an additional Six Hundred Thousand Four Hundred Eighty-Nine Dollars and Eighty-Five Cents ($600,489.85).
