2007/04/18 Council Agenda Packet

1 2 April 6,2007 Page 2 held to present and discuss the results of our draft report and address City review comments. Adolfson will prepare meeting minutes for each meeting. Project Management This task includes communication within the project team(City staff and Consultant team members),quality control,scheduling, budget,staffing, and general project administration. Deliverables: • Monthly invoices and progress reports; • Two meetings with City staff; and • Meeting minutes for the two meetings. TASK 2—DATA COLLECTION AND FIELD RECONNAISANCE The project site has been the subject of numerous studies,including:flood analyses, surveys, upgrade plans, restoration,subsurface,and other investigations.For this task, we will review and assess selected information in our files and information made available to us by the City that pertain to current site conditions. We will document data gaps identified by our review. Data Collection We will review selected information from our files,readily available information related to the project objective, and information provided by the City(e.g. aerial photos,FEMA Flood Study,LIDAR data, GIS data,property ownership data,topographic maps)to characterize existing conditions. Adolfson will review this information and, if necessary,work with the City to develop a list of additional data that may be available. Geotechnical Data Collection and Assessment We will review selected geologic maps and subsurface exploration data for locations in and near the project site and that are contained in Adolfson team member Shannon&Wilson's files. We will also review subsurface data for the WPCF and existing Ievee system that the City provides to us. We will use these data to assess subsurface conditions. Field Reconnaissance We propose two field reconnaissance efforts. The first is a three-day field reconnaissance that will be performed by two or three specialists on the Consultant team. They will verify site conditions, document photographically the condition of the existing levees,qualitatively assess levee conditions, locate drainage structures,and develop a general knowledge of the area. Two of the three days will be on land,and one day will be on the water. We assume that the City's boat and driver will be used for the on-water reconnaissance. This reconnaissance will be performed to the extent possibleduringlow tide. The second is a one-day field reconnaissance to be performed by two specialists on the Consultant team to investigate and document current drainage patterns. -Adolfson will identify any areas that will require specific survey(e.g. invert elevations);we assume that if a detailed survey is needed,it will be provided by others. Deliverables:
