WETA Redwood City Ferry Terminal – Site Feasibility Report July 9, 2012 | DRAFT Report DRAFT DRAFT 2012-7-09 Redwood City Ferry Terminal - Site Feasibility Report July 9, 2012 | DRAFT Report Prepared for: Water Emergency Transportation Authority (WETA) Prepared by: KPFF Consulting Engineers Subconsultants: Coast & Harbor Engineering FMG Architects DRAFT Water Emergency Transportation Authority Redwood City Ferry Terminal - Site Feasibility Report DRAFT 2012-7-09 INTRODUCTION This Site Feasibility Report document sets forth preliminary assessment of existing site conditions in support of Planning Level Concept Design and Alternative Selection for a potential ferry terminal facility for the San Francisco Bay Area Water Emergency Transportation Authority (WETA) in Redwood City, California. The Preliminary Concept Design to date has focused on Site Assessment and Coastal Engineering. Many of the typical project costs are similar for different WETA terminal sites, but dredging and coastal conditions can result in significant costs that vary considerably between individual sites. Since these coastal conditions are critical to consider for project viability at the proposed site, initial design work and site investigation has focused on bathymetric survey and preliminary coastal analysis. The other major focus for preliminary design included coordination with project stakeholders and establishment of site definition, including preliminary understanding of landside/waterside boundary constraints for use in concept design. Stakeholders that participated in meetings with WETA and the design team included the Port of Redwood City, San Francisco Bay Conservation and Development Commission (BCDC), City of Redwood City and the San Francisco Bay Trail. General site design assumptions for the proposed Redwood City terminal are as follows: ° The site could serve as a ferry terminal for a passenger ferry route to downtown San Francisco or East-Bay (Oakland/Alameda). ° The terminal design would include waterside improvements similar to those implemented at the recently completed South San Francisco terminal. Major marine infrastructure would include pilings, floats, fendering, and gangways. Upland components would include landscape and trail/public access; a landside canopy for waiting passengers; and other upland site improvements including utilities, fencing, gates, kiosks, and parking. ° The upland terminal would be unmanned, with no public restroom. However, as an origin terminal, a small on- site building/shed containing a supply/storage room, crew room with lockers, and a room for network systems (Clipper/Next Bus) would be required. ° The Redwood City terminal would be an origin terminal and would likely feature overnight berthing due to the route distance. As an origin facility, on-site fueling facilities would be required. No existing fuel lines are currently in the vicinity, so the site would need diesel fuel tanks similar to those at the proposed Central Bay Operations and Maintenance Facility in Alameda. This Site Feasibility Report document was prepared following completion of a bathymetric survey, preliminary site- specific coastal analysis, and initial meetings with project stakeholders. The intent is to identify and describe significant engineering constraints and challenges associated with the site prior to studying more site-specific upland design and terminal layout. PREFERRED TERMINAL SITE LOCATION AND BOUNDARIES PPreviousrevious Sites Considered Prior to this Report Intermodal and Terminal Access Study Scoping Reports prepared for WETA by ARUP in June 2002 identified potential terminal locations that would support expansion of ferry services in the Bay Area. This report identified possible future ferry terminals at many new cities, including Redwood City. It discussed potential sites; future development potential; existing/future traffic conditions; and access for parking, transit, and pedestrians/bicycles. The Draft Working Paper Scoping Study showed three potential locations for a terminal in Redwood City. One of these sites was located on Westpoint Slough and is the preferred location discussed in this Site Feasibility Report. The second and third locations were located further to the south along Redwood Creek, and were referred to as F dock and Wharf 5. These locationsDRAFT are not preferred due to the additional time required (more than 5 minutes) to travel down Redwood Creek (which is a no-wake zone) and were not considered further in this Site Feasibility Report. PProjectroject SiteProject Site --- Existing ConditionsConditions,, Adjacent UsesUses,,,, and Property Ownership The following is a summary of important general issues associated with the site and the surrounding area: Water Emergency Transportation Authority Page 1 Redwood City Ferry Terminal - Site Feasibility Report DRAFT 2012-7-09 ° The Port of Redwood City contains Redwood Creek, a federally maintained navigation channel. Several significant sloughs drain into the Creek; the largest of these is Westpoint Slough where the preferred terminal site is located. The coastal conditions created by this location are further described later in this memorandum. ° The terminal site is approximately three miles north of Redwood City’s downtown business district at the end of Seaport Blvd., just west of the Pacific Shores Center Office Complex at the confluence of Westpoint Slough and Redwood Creek as shown in FFFigureFiigguurreeigure 2.2.2. A regional map of greater Redwood City is shown in FFiigguurreeFigure 111.1 DRAFT FFiigguurreeFigure 111 – Redwood City Regional Map Water Emergency Transportation Authority Page 2 Redwood City Ferry Terminal - Site Feasibility Report DRAFT 2012-7-09 DRAFT Figure 222 – Vicinity Map and Site Access Water Emergency Transportation Authority Page 3 Redwood City Ferry Terminal - Site Feasibility Report DRAFT 2012-7-09 ° The upland portion of the terminal site would be within a 9.2-acre parcel (San Mateo County Assessor’s parcel #0543-00-380) owned by the Port of Redwood City. The site is zoned General Industrial (GI) and its Redwood City General Plan Land Use designation is Mixed Use – Marina, with a notation about the potential future ferry terminal. The ownership of this parcel and surrounding adjacent parcels is shown in Figure 333,3 with green designating parcel areas under Port of Redwood City ownership/control. DRAFT Figure 333 – Parcel Ownership Map Water Emergency Transportation Authority Page 4 Redwood City Ferry Terminal - Site Feasibility Report DRAFT 2012-7-09 ° This 9.2-acre parcel is owned by the Port of Redwood City and is currently leased by RMC Pacific Materials (CEMEX). We understand that the Port has, or will be, negotiating a new lease with CEMEX for the preferred site, and the new lease will contain similar provisions to the existing lease. These provisions would allow the Port to reclaim a portion of the property for the future ferry terminal. ° The terminal would not require use of the entire Port-owned parcel. The terminal site would include the northernmost area of this parcel along the waterfront with Westpoint Slough, with a portion of the remaining site area expected to be utilized for parking and circulation for automobile and bus traffic. The remaining area to the south of the parking facility would not be used for the terminal and could continue to be utilized by CEMEX or other similar Port tenants for materials stockpiling and handling, similar to the existing current use. ° The upland site survey obtained from the Port of Redwood City is believed to be in NGVD ’29 +100’ vertical datum (based on the City of Redwood City Attachment J – Comparison of Datum figure), while the new bathymetry is in MLLW datum. The elevations from the upland port survey can be converted to MLLW by subtracting 100’ to convert from the port datum to NGVD ‘29 and then adding 4.13’ to convert from NGVD ’29 to MLLW. Revising/converting upland contours or providing a new upland survey was deemed unnecessary for this level of conceptual site feasibility design. ° The upland site is generally flat, level land, between elevation +10 and +14 feet MLLW datum, with material stockpiles up to 34 feet MLLW across the site as shown in Figure 444.4 High tide (MHHW) in this area is approximately 8.22 feet MLLW as described later in this report. The stockpiles would be removed from the site prior to terminal construction. ° Waterside, an existing concrete pier (and steel ship hatch covers that span between the pier and shore) would be demolished. See FigureFigureFiguresFigures 444 and 555 for existing conditions. Refer to the discussion later in this document of potential new and existing overwater coverage.
