GPA No. 2020-01 & ZOA No. 2020-02 — One Broadway Plaza March 30, 2020 Page 7 2. Substantial changes in circumstances that would result in new or substantially more severe impacts than disclosed in the previous EIR; or 3. Significant new information has come to light that shows there will be new or substantially more severe impacts than disclosed in the previous EIR. If some changes or additions to the previously prepared EIR are necessary, but none of the conditions specified above are met, the lead agency shall prepare an Addendum. In accordance with the State CEQA Guidelines, since none of the conditions specified in section 15162 are present, an Addendum to the previously -certified 2004 EIR is the mandated form of environmental review for the One Broadway Plaza project. The Addendum focuses on the potential environmental impacts associated with the project that might cause a change in the conclusions of the certified 2004 EIR, including changes in circumstances or new information of substantial importance that would substantially change those conclusions. The Addendum considers whether the project results in new or substantially more severe impacts than were disclosed in the 2004 EIR and finds that no supplemental or subsequent EIR is required for the proposed development. Pursuant to State CEQA Guidelines section 15164(c), an addendum to a previously -certified EIR is not circulated for public review. The Addendum is included with this staff report as Attachment 9. Pursuant to State CEQA Guidelines section 15164(d), the Planning Commission must consider the Addendum together with the 2004 EIR before making a decision on the project. Previous CEQA Documentation The 2004 EIR (SCH No. 99101047) was prepared to evaluate the potential impacts associated with the adoption of the One Broadway Plaza project, which is anticipated to result in potential development of approximately 518,000 square feet of office and commercial development. The 2004 EIR considers the environmental impacts relating to air quality, cultural resources, land use, geology, hydrology, safety hazards, population/housing, public services and utilities, aesthetics, noise, traffic and circulation. A mitigation monitoring and reporting program, findings of fact, and a statement of overriding consideration were adopted with the 2004 EIR. As part of the 2020 Addendum to the 2004 EIR, the original mitigation monitoring and reporting program must be readopted by the Planning Commission; no changes to the mitigation measures were identified as necessary through review and preparation of the 2020 Addendum. The EIR identified several unavoidable adverse impacts associated with this project. These impacts pertain to transportation, air quality, utilities and services systems, aesthetics and cultural resources. Unavoidable transportation impacts include traffic impacts that will reduce the level of service on roads and intersections to an unacceptable level. Although some intersection improvements are required, other street improvements needed to mitigate the project are infeasible due to the significant land use impacts from the widening. Air quality impacts consist of long-term emissions, particularly nitrogen dioxide (Nox). The project will impact utility and service systems in the area, as it will interfere with broadcast and television signals in the project area. 75A-12
