2.3 Access Piers <br />At each dock or group of docks, there is an access pier that is supported by piles over the rip-rap <br />and connected to the docks with an aluminum ramp. At docks A, B-D, E/F, and G/H, the access <br />pier consist of a concrete apron, and precast concrete beams connected to concrete piles and <br />concrete bent cap. At docks J, K, L/M, N/O, and P/Q, the access pier consist of a concrete apron, <br />and timber beams and decking connected to timber piles and bent caps. <br />2.4 Gangways <br />All ten gangways were replaced during the 1990 renovation and are 38-feet long aluminum <br />structures. They appear to be in serviceable condition and without any noticeable deterioration or <br />corrosion. <br />2.5 Buildings <br />The Harbor Master’s office and two over-water restrooms are pile-supported over the marina. They <br />appear to be typical wood-framed structures. The Harbor Master’s office is accessed by a timber <br />ramp, which consist of timber beams, piles, and bent caps. At the restrooms, timber beams and <br />decking connect the restroom directly to the sidewalk. <br />In addition, there are a two other structures supported by piles over the water, namely the Blue <br />Dolphin Restaurant and a former observation deck (now closed), located north and south of Pier A, <br />respectively. The observation deck was heavily damaged by fire, with only the foundation and piles <br />still remaining. <br />2.6 Utilities <br />Site utilities systems are as described in the subsequent sections. <br />Sanitary Sewer <br />Sanitary sewer services at the Site convey sewage to the City of San Leandro’s municipal system. <br />The services that are to be demolished include those at the Harbor Master’s office, refueling dock, <br />restroom facilities, and Blue Dolphin platform. See the Site Map in Appendix A for locations. <br />The Harbor Master’s office sewer system is comprised of a gravity pipe running below the <br />suspended deck and gangway, to a location on shore where it connects to a City main. Demolition <br />of the Harbor Master’s service shall include removal of all pipe to a point five (5) feet on the land- <br />side of the top of bank. The existing service pipe is to be capped at that location. <br />The floating docks do not contain individual sanitary sewer services for each slip. Rather, the <br />refueling dock serves as a sewage pumping station for vessels, utilizing two (2) pumps located on <br />the refueling dock deck. Both pumps shall be removed and salvaged, including pump cabinets, <br />hoses, valves, electrical services, and other related appurtenances. The piping shall be removed <br />to a point no less than five (5) feet inside the top of bank and capped at that location. <br />The five (5) restroom facilities’ (‘A’ through ‘F’) sewer system services were buried and not <br />observable at the time of inspection. The services are assumed to be four (4) or six (6) inches in <br />diameter and connected to the municipal main on shore. Demolition of the restroom facilities’ <br />21
