EXHIBIT "A" <br /> SCOPE OF SERVICES AND TIME SCHEDULE <br /> Task 1. Surveying Services <br /> CONSULTANT shall provide supplemental surveying for the proposed Concrete Box <br /> Culvert Relocation Project. This updated supplemental information is required for base <br /> mapping purposes associated with the preparation of Construction Documents. This <br /> information will be added to existing survey information as part of the aerial topographic <br /> survey. Supplemental field survey will include 30 to 40 feet on each side of the <br /> proposed concrete box culvert relocation alignment, and will include location of surface <br /> features, grades, utility boxes. The accuracy will be to 0.1' when possible. <br /> Task 2. Hydraulic Analysis <br /> CONSULTANT shall update the Redwood Creek HEC-RAS storm drainage model using <br /> site specific survey data. The model will be run using the 30-year event peak flow rate <br /> from the City's Storm Drainage Master Plan, and the FEMA 100-year peak flow rate. <br /> CONSULTANT will review differences in box culvert sizing for these flow rates. If a <br /> design flow rate of less than a 100-year storm is used, CONSULTANT will review the <br /> overflow flow path of excess flows. CONSULTANT will prepare a design report that <br /> documents box culvert sizing and key design parameters verifying the design intent for <br /> the relocated box culvert. <br /> Task 3. Civil Improvement Plan Preparations, Coordination & Meetings <br /> Task 3a. Data Research and Coordination: <br /> CONSULTANT will research the City of Redwood City records and other <br /> information available as to the location of existing utilities and other improvement <br /> plan features and pertinent site features. CONSULTANT shall plot these into the <br /> base drawing map of the Proposed Concrete Box Culvert Construction <br /> Documents. CONSULTANT will evaluate which utility will need to be relocated as <br /> part of the realignment of the box culvert. These existing utilities can then be <br /> taken into account in the development pian for the area. <br /> Task 3b. Prepare 30% Construction Documents <br /> Specific work to be performed during this phase will include at a minimum: <br /> a. Incorporating comments from City based on preliminary meetings and <br /> review of concept plan <br /> b. Developing site improvement plan for the improvement area <br /> c. Street improvement, grading design and detail preparation <br /> d. Storm drainage detail design <br /> ATTY/AGR/2011.140IDESIGN AGREEMENT BKF <br /> REV:12/22/11 <br /> Page 11 of 17 <br />
