However, implementation of mitigation measures MM4.5-1 and MM4.5-2 would ensure that contaminated sites undergo remediation activities prior to development activities, thus reducing the impacts below a level of significance. Discussion is provided on page 4.5-18 of the DEIR. For each of the parcels that are a proposed as part of the Developer Project, Phase I Environmental Site Assessments (ESAs) were conducted by Converse Consultants in April 2010 in accordance with ASTM Practice E1527-05 standards. The proposed project area was assessed by block; thirteen separate ESAs were prepared. The ESAs were prepared using and extensive record search as well as field reconnaissance surveys. The results of these ESA are summarized in the Chapter 2 of the Final EIR (Changes to the Draft EIR). The ESAs concluded that no further investigation was needed, with the exception of soil vapor surveys on Blocks 1 and 6. In accordance with mitigation measure MM4.5-1, the project Applicant would be required to undertake a Phase II ESA soil sampling plan to ensure that potential impacts remain less than significant.
