TJ KM Transportation Consu Itants Project Pedestrian and Bicycle Circulation TJKM reviewed the proposed project in terms of its potential effects on local pedestrian and bicycle circulation. The project will construct new sidewalk along the entire project frontage on Oakwood Drive and EI Camino Real, and internal pedestrian walkway connections between the project's building access points and the new public sidewalk on Oakwood Drive will also be provided. Crosswalks with pedestrian signal indications are provided across Oakwood Drive, Dumbarton Avenue, and the north leg of EI Camino Real at their signalized intersection, but no crosswalk is provided across the south leg of EI Camino Real adjacent to the project site. Wheelchair curb ramps are provided at both ends of the crosswalks. The only local facilities available to bicyclists are roadways that must be shared with motorized vehicles. The existing roadway width on EI Camino Real does not appear to allow for adding bike lanes while maintaining the existing number of traffic lanes. On Oakwood Drive and connecting residential neighborhood streets to the west, automobile speeds are generally low (25 miles per hour posted speed) and traffic conditions are generally favorable for bicyclists. Parallel curb parking will be prohibited along the project site frontages on Oakwood Drive and southbound EI Camino Real, which will avoid additional parking friction with bicyclists. Therefore, no impacts are expected to local pedestrian and bicycle circulation due to the proposed project. Project Site Access and Circulation TJKM reviewed the project site plan to evaluate on-site circulation and access. The site plan shows one full access driveway to be provided on Oakwood Drive approximately 225 feet south of EI Camino Real. Spacing of the driveway from the Oakwood Drive intersections at EI Camino Real and Leahy Street is expected to be adequate given the 25 mph speed limit, the existing speed hump immediately west of the proposed driveway, and the low net project trip generation expected. Additionally, the maximum peak hour 95ih-percentile queue length of approximately 210 feet on eastbound Oakwood Drive extending back from EI Camino Real under Existing plus Proposed Project Conditions is not expected to block the project driveway. Within the project site, circulation is expected to be adequate. The site plan shows parking aisle and internal roadway widths that are adequate for internal vehicle, pedestrian, and bicycle circulation purposes. The entrance driveway at Oakwood Drive would be more than 25 feet wide, and the internal circulation driveway and parking aisle would be approximately 24 feet wide. These widths are expected to be adequate for two-way on-site vehicle circulation, especially given the low maximum peak hour trip generation of 23 vehicles. On a recent field visit, TJKM found that sight lines from the proposed project driveway location are generally adequate given the flat grades, low prevailing vehicle speeds, and proposed prohibition of curb parking on Oakwood Drive adjacent to the project site. To provide adequate sight- distance for motorists exiting the proposed project driveway on Oakwood Drive, TJKM recommends that all landscaping along the project street frontage that is located in the line of sight of traffic approaching the project driveway in either direction shall be limited to plants with foliage no more than three feet above the closest adjacent curb elevation, or trees with canopy foliage no less than seven feet above the closest adjacent curb elevation, or other dimensions as specified by the City Engineer. The line of sight is defined as an area within 15 feet of the driveway edge between the street curb and a point I 5 feet behind the back of the sidewalk or walkway, or as otherwise specified by the City Engineer. This measure is expected to address any potential visibility issues for motorists exiting the proposed project driveway.
