Moss Street Beach Access Improvements
Award
Structural Engineering Project
Description
The project completely replaced the City’s existing beach access at the end of
Moss Street. The existing stairs were damaged by the coastal environment
and slope erosion. The stairs were non-ADA compliant with unsafe conditions
including a 3-ft drop off at the end of stairs. The City saw an opportunity to
refresh the facility while improving safety and resilience, and enhancing
aesthetics and accessibility. The project included adjacent street, storm drain,
and ramp improvements, expanded upper viewing area with bike racks and
safety bollards, additional intermediate landings, rest areas and lookouts, new
wooden privacy fencing, and a new lifeguard tower. The new stairs required a
combination of slab on grade stairs and suspended slab pedestrian bridges
on 30” diameter piles as well as H=4- to 8-ft high retaining walls with
conventional spread footings and soldier pile-type foundations. Stantec
determined the limits of the pedestrian bridge considering bluff retreat, sea
level rise, wave runup, and other results of coastal hazard evaluation. Stantec
coordinated with Industrial Design Research, Inc. (IDR) to design the CIDH
foundation and a custom removable steel support frame for the prefabricated
lifeguard observation tower. Project elements included topographical
mapping, utility research, geotechnical investigation, environmental
documentation, concept layout and alternative studies, civil and structural
engineering, landscaping, and irrigation.
