Desired levels of illumination shall be calculated consistent with City of San Leandro and Caltrans standards. This includes specification of the types of luminaires, cutoff and wattage, and average to minimum ratios for maintained illumination. TJKM shall prepaze preliminary street lighting plans that make maximum use of existing street lighting poles and fixtures, yet provides the desired illumination standards. The 30% plans shall show the modifications required for the project including new poles and luminaires, pull boxes, etc., but not specific wiring connections. g) Landscapin Pg lans Preliminary landscape plans will show planting for the on-ramp edge and the hardscape treatment for medians. The Planting plan will locate general plant types (groundcover, shrub, and trees) as well as designating specific paving treatments for the medians. Preliminary special provisions and cost estimates for the Landscape work will be prepared. There will be no irrigation submitted during this phase. 2.5 Engineer's Estimate Under this task, MTCo will prepare a preliminary construction cost estimates for the roadway and traffic signal improvements. 2.6 Draft Specifications MTCo will develop a list of special provisions that may be appropriate for the project based on the preliminazy design. We will also gather city standard specifications and other standard boilerplate information to be used in preparing the final set of contract documents. 2.7 Initial Site Assessment Under this task, BASELINE Environmental Consulting will prepare an Initial Site Assessment (ISA)/Hazardous Materials Technical Report to Caltrans requirements to evaluate existing information regarding hazardous materials and wastes in the study area. This task will include a records search of site databases to document known contaminated sites, historical land use research to identify former land uses at or adjacent to the study area associated with hazardous material use, a review of previous environmental investigations at and near the study azea, and a field reconnaissance. The activities and findings in the ISA/technical report will be presented in a report with the Caltrans ISA checklist included as an attachment. Detailed recommendations will be made for additional investigation or other action, if warranted by the findings of the ISA/technical report. 2.8 Aerially. Deposited Lead Study Under this task, BASELINE Environmental Consulting will prepare an aerially deposited lead study, including the sampling and analysis of shallow soil samples within the Caltrans right-of- way that will be affected by the project. We have assumed that an encroachment permit will be obtained from Caltrans for the field work. BASELINE will adhere to all requirements of the permit. Typically, compliance would require BASELINE to submit plans showing sampling locations and work locations to Caltrans and notify them of sampling dates and times. All sampling activities will be performed in unpaved areas adjacent to ramps and will not require lane closure. Twenty soil samples would be collected using hand-operated sampling equipment. Pre-cleaned, 6-inch stainless steel liners would be pushed into shallow soils, then retrieved. Each sample would be analyzed for total lead using EPA Method 6010A. Samples containing total lead concentrations exceeding ten times the Soluble Threshold Limit Concentration (STLC), a State hazardous waste threshold, would also be analyzed for soluble lead using the Waste Extraction ACTIA 1 L• I-880/Washington Avenue Interchange Improvements June 2005 COSL Project No. 144-39-007 Page 19 of 35
