Holly_Street_Bridge_–_ISMND.pdf

This is an Initial Study and Mitigated Negative Declaration (ISMND) prepared by the City of Pasadena for the Holly Street Bridge Seismic Retrofit and Rehabilitation Project. The document outlines the environmental review for a federally funded infrastructure project administered through the Highway Bridge Program (HBP) by the California Department of Transportation (Caltrans). The proposed project involves seismic retrofit and rehabilitation work on the Holly Street Bridge, with the City of Pasadena as the lead agency responsible for project implementation. The ISMND identifies potential environmental impacts and mitigation measures necessary to avoid or reduce significant environmental effects to a level of insignificance. The document serves as the environmental compliance basis for the construction management and inspection services contract opportunity, which requires the selected consultant to oversee all construction activities and support City staff operations throughout project execution.

The ISMND addresses environmental impacts including construction-related effects such as noise, dust, traffic disruption, and temporary land use changes, with identified mitigation measures to address these concerns. The document establishes that with implementation of proposed mitigation measures, the project will not result in significant unmitigated environmental impacts. As a federally funded project through Caltrans, the work must comply with federal environmental review requirements and standards. The ISMND is a critical prerequisite document that allows the project to proceed to the construction phase, where the construction management consultant will be responsible for ensuring compliance with both environmental mitigation requirements and federal funding stipulations during project execution.
