While the City of Imperial Beach has not yet received a request from your tribe to be notified of specific projects within a designated geographic area, we are reaching out to all groups listed on the California Native American Heritage Commission’s Sacred Lands File consultation list in a good faith effort to provide notification of the proposed Project to groups that are traditionally or culturally affiliated with the geographic area of the proposed Project.
PROJECT NAME: Palm Avenue Multimodal Corridor Project

PROJECT DESCRIPTION:
The Project is designed to transform Palm Avenue into a safer, more accessible, and visually enhanced multimodal corrdior. The Project is approximately 5,711 linear feet and covers approximately 59.8-acres.
The Project is proposing several improvements including establishing Class IV protected bike lanes, widening existing sidewalks, installing shade canopy trees, ornamental lighting, improving median landscape, replacing median vehicle lighting, constructing curb extensions with directional ramps, and rebuilding alley entrances, driveways and curb ramps to be ADA compliant.
The Project falls in Township 18 South, Range 2 West, and Sections 19, 20, and 29 of the Imperial Beach, California U.S. Geological Survey 7.5-minute Quadrangle (Figure 1). The City of Imperial Beach will act as the lead agency under California Environmental Quality Act (CEQA).

During the survey, one newly identified historic period site, PA-MM-S-001, was recorded on the surface consisting of a refuse scatter of glass and ceramic fragments.
