Copies have been sent to the State Clearinghouse for distribution and for the different State agencies to review. A copy of the Mitigated Negative Declaration, Mitigation Monitoring Plan and Initial Study is attached. The public review period for the document was from January 9, 2001 to February 7, 2001. • The City, on February 7, 2001 received a comment letter from Caltrans regarding the prescribed mitigation measure to adjust the ramp metering times at the eastbound and westbound Davis Street on -ramps to northbound I-880. In this letter Caltrans suggests other measures to mitigate this project. Caltrans had previously submitted a memorandum dated August 30, 2000 that supports adjusting the ramp metering times. It is stars determination that the mitigation measure stated in the Mitigated Negative Declaration will be adequate. The City and Caltrans will coordinate their efforts on the necessary adjustments. • The document identifies that hazardous materials exist on the site due to the history of various industrial uses on the properties. Hazardous materials found on -site include lead, polychlorinated biphenyls (PCBs), a black sand fill, and polynuclear aromatic hydrocarbons (PNAs). The remedial action plan prescribes excavating the contaminated areas on site to depths between one to five -feet. This work would mainly take place on the three westerly properties that are being assembled and portions of the adjacent creek bank. The mitigation measures will require the trucks hauling away the soil to be staged on site and to take appropriate dust control measures during this excavation and fill process. This work would be conducted with the oversight of the Regional Water Quality Control Board and the City's Environmental Services Manager. In addition, the anticipated work within the San Leandro Creek bank or creek bed would require approval from the Army Corps of Engineers and the Alameda County Flood Control District.
