Palm Avenue Complete Multimodal Corridor Project

The Palm Avenue Complete Multimodal Corridor Project, managed by the City of Imperial Beach, aims to transform approximately 1.3 to 1.75 miles of Palm Avenue between Rainbow Drive and Georgia Street into a context-sensitive, multimodal corridor. The project focuses on improving safety, mobility, and drainage for pedestrians, cyclists, transit riders, and motorists through the integration of complete-street infrastructure, including protected bike lanes, sidewalk widening, signal upgrades, and ADA-compliant curb extensions and ramps. Key construction activities include demolition, site preparation, grading, roadway paving, and architectural coating. The project is supported by a comprehensive environmental review under the California Environmental Quality Act, including a Mitigated Negative Declaration. Technical assessments have been completed regarding geotechnical risks, noise levels, biological resources, and cultural resource inventories. Environmental safeguards include a Phase I Initial Site Assessment to manage hazardous materials, a hydrology and hydraulics report for flood risk and stormwater compliance, and a construction health risk assessment. The project requires a Coastal Development Permit and adherence to FEMA Zone AE floodplain requirements. Coordination with California Native American tribes has been initiated to protect tribal cultural resources. Primary project oversight is provided by Public Works Director Juan Larios.
