SUNOL BOULEVARD/I-680 IMPROVEMENTS PA&FD The project area has been surveyed and analyzed for water quality and storm water runoff by recent projects, including the I-680 Express Lanes from State Route 84 to Alcosta Boulevard Project(EA 04-0Q3000). A Water Quality Assessment memorandum based on recent reports in the project area will be prepared to evaluate the potential for water quality impacts to existing surface water and/or groundwater resources and the potential for hydromodification within the project limits. Subtask 4.13 Final Technical Reports The technical reports for the previously defined studies will be updated based on review comments from Caltrans and CITY. A matrix of review comments and their responses for each report will also be compiled to track and document how each comment is addressed. CONSULTANT will submit technical reports once in draft and once in final form, the intent being one review and one revision per document, unless otherwise specified. Extended rounds of revisions are not included in our estimated level of effort.
