BACKGROUND: The Riverside Public Utilities Department (RPU) owns and operates an existing 16 million gallon (MG) water storage facility known as Linden Reservoir. Linden Reservoir is situated immediately adjacent to Evans Reservoir, which also has a 16 MG capacity. These reservoirs are operated together and are a major source of water supply for the City. This reservoir complex is generally located at the southeast corner of Linden Street and Cranford Avenue (Attachment 1). The Linden Reservoir (Linden) was originally constructed in 1927 and has undergone several rehabilitations over the years. Most recently in the 1980's, Linden underwent an extensive rehabilitation which involved a structural overhaul of its concrete lining system to repair cracks and ensure water-tightness. Today, Linden's existing steel framed roof, which was built in the 1950's, shows obvious signs of corrosion and other damage. In 2009, under their contract for the design of the Evans Reservoir Replacement Project, AECOM conducted a condition assessment of Linden. Their report confirmed the poor condition of Linden's roof and recommended that a comprehensive roof replacement be planned in the near future.
