Minutes - San Leandro City Council Meeting - December 20, 1993 Page - 8 - NEW BUSINESS (continued) Gary Oates, ESA, described the project area and said it contained 172 acres of land that was once tidal marsh but has been diked off over the years. He described the Plan, which will enable Bay water to enter and drain off the site adequately and will bring in tidal action through channels and culverts. He said the Plan builds habitat islands for endangered species using material excavated from the culverts and channels. He discussed the history of the study on the project which began in 1990 and has involved numerous meetings with resource agencies and citizens. He said additional analyses, including sampling, have been conducted to address toxicity issues, and a biological assessment has been made to ensure the plan will not harm endangered species. He discussed phasing of the construction and said the resource agencies want the entire project constructed at one time; he said it would be done in such a way as to cause the least disturbance to wildlife. He said a site assessment of the East Marsh area was conducted related to the potential for hazardous materials, in coordination with the Regional Water Quality Control Board. He said the probability of explosion due to nitrostarch is low because the material decays in sunlight and loses its potential for explosion when wet. He discussed the impact of the public trail access and the proposed alignment. He spoke regarding comments made at tonight's meeting and said ESA used the data from the PEA for Citation but did its own analysis. He said all of the material was submitted to the Regional Water Quality Control Board, which has said their concerns have been addressed and they do not see any potential for adverse toxic ecological effects. Mr. Oates said the Sierra Club letter was a comment letter on the Supplemental EIR on Citation's project and raised points regarding segmentation. He said this project has been developed as an independent project and the resource agencies required that it function separately. He said, however, that they also looked at how it might work with Citation. He said the Sierra Club also discussed the link of this project to the dredge disposal site. He said the two sites do not work together. He said there was a comment about the project component that proposes to raise 900' of levee along the south side of Roberts' Slough and how that related to flooding on Citation's property. He said this work is intended to bring more water into the East Marsh and proposes to raise the levee at that location so that it will better control water circulation. Regarding whether testing should be done in Roberts' Slough and East Marsh, he said they have done an assessment, have had regional agencies responsible to evaluate toxicity out to the site to direct where to
