Safety Modifications to Municipal Pier
San Francisco Maritime National Historical Park has been monitoring the condition of the Aquatic Park (Muni) Pier for several years. This monitoring includes periodic assessments by consulting engineers on the stability of the primary pier structure and of secondary components such as walls, benches and light poles. The most recent assessment report included the following observations and recommendations:
• Previously recommended load limit (50 pounds per square foot) remains unchanged.
• The parapet wall/pedestals that are supporting the street lamps are severely deteriorated to the point where some street lamps are at risk of collapsing; recommendation is removal of street lamps.
• Plywood reinforcing on the concrete parapet wall is obscuring the condition of the wall and preventing ongoing assessment of the wall; recommendation is removal of the plywood.
• Spalling concrete on the outer perimeter of the pier is in danger of separating from the pier and falling into the water; recommendation is alerting swimmers and boaters to risk.
• Deteriorated concrete on the outer perimeter of the pier is exposing rusted and protruding rebar at water level; recommendation is alerting swimmers and boaters to risk.
The observations and recommendations detailed above led to this proposed project, which is to undertake the following:
• Remove of all 25 street lamps, and cap related electrical wiring.
• Remove the plywood reinforcing and install of a new metal railing system approximately one foot inboard of the concrete parapet wall. The new railing will prevent visitors from leaning against the deteriorated parapet wall but still allow fishing from the pier.
• Replace the existing metal railing, which itself significantly deteriorated. The new and replaced railings will result in a metal railing system following the entire perimeter of the pier. The location of the railings can be seen in the attached Exhibit A.
• Installation the new railing will require the relocation of the existing concrete benches. The benches will be moved away from the parapet wall.
• Install warning signs on the pier. The location of the signs can be seen in the attached Exhibit A and the sign text can be seen in the attached Exhibit B.
