PC-2009-39, STONERIDGE DRIVE SPECIFIC PLAN AMENDMENT/STAPLES RANCH PROJECT

EXHIBIT A ADDENDUM TO THE ENVIRONMENTAL IMPACT REPORT FOR STONERIDGE DRIVE SPECIFIC PLAN AMENDMENT/STAPLES RANCH State Clearing House Number 2006062053 November 5, 2009 Background and Prior Environmental Review The Ice Center consists of four National Hockey League -sized ice rinks and would utilize about 8 acres of the 17 -acre community park. The proposed structure will be approximately 45 -feet tall and is intended for uses such as ice hockey, figure skating, speed skating, public skating, and other similar activities. The Ice Center can have seating for up to 2,200 spectators; however, the ice center developers have indicated that they may reduce seating to 1,475 or 1,400 seats. On February 24, 2009, the Pleasanton City Council certified the Staples Ranch Environmental Impact Report (EIR), approved findings required by the California Environmental Quality Act (CEQA) and adopted a Statement of Overriding Considerations, concluding that the potential benefits of the Ice Center Alternative outweighed the environmental risks of the Ice Center Alternative. The City Council also approved a Specific Plan Amendment with an extension of Stoneridge Drive from Trevor Parkway to EI Charro Road. In June 2009, the City Council authorized preparation of a Supplemental Environmental Impact Report (SEIR) to consider the environmental impacts, if any, of a two lane Stoneridge Drive extension as compared to the four lane roadway extension included in the Amended Stoneridge Drive Specific Plan and to update certain studies. The SEIR was reviewed by the City Council and certified on . The EIR certified on February 24, 2009 and the SEIR certified on shall jointly, for simplicity sake, be referred to in the Addendum as the "EIR". Purpose of EIR Addendum The purpose of this addendum is to provide environmental review of a proposed increase in size of the Ice Center. The EIR evaluated the impacts of the proposed Ice Center at approximately 138,500 square feet in size. The Ice Center is currently proposed to be approximately 141,679 square feet due to a design modification to the entry portion of the building. In response to a City initiated architectural peer review, the applicant modified the entry element of the building in an effort to improve the design, aesthetics, and overall appearance. Thus, the additional 3,000 square feet is attributed to an increase in the main entry/lobby and foyer area by approximately 1,500 square feet for the first and second floors. This Addendum has been prepared in accordance with the CEQA Guidelines Section 15164 and amends the Stoneridge Drive Specific Plan Amendment/Staples Ranch EIR. The evaluation, contained below, determines that the proposed project does not contain 1
