Document Description
The purpose of this project is to rehabilitate
and perform minor repairs on the existing Robert I. Schroder pedestrian bridge to address multiple deficiencies
and prevent further deterioration of the bridge's serviceability and aesthetics. The existing bridge carries
pedestrian and bicycle traffic over Treat Boulevard as part of the Iron Horse Trail and is located approximately
0.3-miles east of I-680. The project proposes to replace bearing pads at two bridge abutments; spot blast and
clean rusted or paint-chipped areas; treat the bridge deck to prevent water intrusion; and repair damaged
concrete areas such as sidewalks and curbs. Other miscellaneous maintenance work includes replacing
pedestrian restriction cabling, pressure washing, and debris removal. Additional improvements will include
park enhancements along the multi-use Iron Horse Trail adjacent to the pedestrian bridge, which will consist of
up to three surface level play cubes on a rubberized pour-in-place surface. Tree trimming and vegetation
trimming and removal may be necessary. Treat Boulevard would remain open to traffic for most of construction
and would require approximately four road closures on separate nights to accommodate the bearing pad
replacement work. An approximately 5-mile traffic detour will be implemented off-site during night work.
Pedestrian and bicycle users on Iron Horse Trail will be temporarily redirected to use the existing street crossing
on Treat Boulevard for approximately 3-4 months while the bridge is closed for repairs. Real estate transactions
such as temporary construction easements may be needed for construction access and staging areas. Utility
relocation is not anticipated. Construction is anticipated to start in Summer 2026 and last for approximately 4-5
months.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
(Sec. 15301[c] and [d] Sec. 15303[e])
Reasons for Exemption
The proposed project is exempt under CEQA Guidelines, Section 15301(c), Sec.
15301(d) and Sec. 15303(e), regarding minor alterations to an existing pedestrian bridge crossing, including
preventative maintenance and rehabilitation work. The current condition of the pedestrian bridge structure did
not result from substantial damage due to an environmental hazard and rehabilitation is needed to meet
current public health and safety standards. Additionally, the park enhancement features consisting of up to
three play cubes on a rubberized pour-in-place surface are minor accessory structures on an existing multi-use
public trail. Negligible or no expansion of use will result from the proposed project.
