weather purposes. Approval of this project will establish the Board of Directors'
independent finding that this project is exempt from CEQA.

construction, contingency, and construction management. This project is included in
the Fiscal Year 2015 -16 Capital Improvement Budget on page TP -13 with a total
estimated project budget of $9.0 million. Staff has conducted a budget analysis of the
Treatment Plant Program budget and concluded that adequate funds are available for
this project.
