Bayer Healthcare LLC Development Agreement Amendment

This action consists of an addendum to the 2021 Subsequent Environmental Impact Report for the Bayer Healthcare LLC Development Agreement Amendment in Berkeley, California. The purpose of the addendum is to address the Second Amendment to the agreement, which involves a programmatic campus land-use adjustment. Specifically, the modification includes a minor boundary change that removes the parcels at 2500 7th Street and 2520 8th Street while adding 811 Carleton Street and adjacent right-of-way, resulting in a net increase of 0.85 acres. Comprehensive technical evaluations were conducted to ensure compliance with the California Environmental Quality Act. A transportation impact analysis concluded that intersections would operate at Level of Service D or better at buildout, requiring no off-site street improvements. Air quality and greenhouse gas assessments determined that additional demolition associated with the boundary change would not alter previous less-than-significant findings. Additionally, a Phase I Cultural Resources Assessment was performed for the Macaulay Foundry at 811 Carleton Street. The City of Berkeley issued a Notice of Determination on September 30, 2026, confirming that the Second Amendment will not result in any new or more severe significant environmental impacts than those previously studied.
