The levee design elevation has accounted for wave run-up, and the access points are protected from wave run-up with a concrete floodwall on the bay side of the access point. Flood barriers are also located at the egress bridge. Elevations along the new trail (bottom of the openings) are generally at least four feet above
A portion of the retaining wall will be “set back” away from Beach Park Boulevard closer to the edge of the trail (as shown below in Graphic A). This will allow the height of the retaining wall to be reduced and more space between the wall and street to be created for landscaping. To soften
The finished Levee Trail will consist of a 12-foot asphalt concrete path, plus a four-foot decomposed granite shoulder on the bay side, and a two-foot decomposed granite shoulder on the inboard (land) side (totaling 18-feet width) with the following exceptions: A section of 10-foot wide path connecting to City of San Mateo pathways (which
The overall height of the levee and wall along Beach Park Boulevard from Bridgeview Park to Shorebird Park will generally be 5-6 feet higher than the current elevation; however, the height of the wall from the walking surface will only be 3.5 feet. The wall will be on the bay side of the pathway.
The final height of the levee wall will vary. From Baywinds Park to the Beach Park Boulevard/Foster City Boulevard intersection, the final height of the wall, including wall cap, will be 3.5 feet above the walking surface. That is the minimum height required for safety due to the drop-off that is created on the bay
A natural metal surface was selected for a number of reasons: Over time, a painted metal surface will exhibit ‘weeping’ through the coating, leading to streaking and staining of the wall surface, and requiring frequent paint touch-ups to maintain a uniform appearance. New paint over existing sun-worn paint can look uneven and splotchy A natural metal surface will age nicely and wear more uniformly
