BACKGROUND In 1988 the Master Plan of the Wastewater Collection System for Palo Alto’s entire sanitary sewer collection system was completed. The Master Plan indicated certain mink main facilities were in need of capacity relief to carry peak wastewater flows and recommended improvements to correct these collection system deficiencies. One of the recommended major capacity relief projects in the Master Plan is a relief sewer construction project that crosses under John Lucas Greet Park. The Charter and Municipal Code of the City of Palo Alto require that a Park Improvement Ordinance be approved prior to any construction on land held by the City for park purposes. The Greer Park Relief Sewer project falls in this category. The project has also been approved with conditions by the Planning Department through the staff review process (see Attachment C). This project is part of the Wastewater System FY 98-99 Capital Improvement Program. DISCUSSION The project involves the construction of approximately 1,800 lineal feet of new 30-inch diameter reinforced concrete sanitary sewer pipe (RCP). The new sewer pipeline will be CMR:386:99 Page 1 of 3 installed at an average depth of 15 feet and at approximately 50 feet offset to the southeast of an existing 27-inch diameter sewer pipe already located under Greet Park (see Attachment B). This new pipe will connect to the new 42-inch diameter sewer pipe of the Amarillo Avenue/Embarcadero Way Relief Sewer Project (CIP #37770) which is curremly under construction. The new sanitary sewer pipe will be installed by open trenching (cut and cover) method, with the first 1,200 feet within Greer Park boundary, and the remaining 600 feet installed within Simkins Court and Colorado Avenue right of ways. Also, in this project, eight new personhole structures will be constructed; three to replace the existing personholes on Colorado Avenue; one new personhole at Simkins Court; and four new personholes in Greer Park. All sewer structures will be installed underground, with the personhole frame and cover installed flush with the surrounding landscape and in the street pavement except for one personhole cover at the end of an existing soccer field (see Attachment B). Only one of five soccer fields at Greer Park will be temporarily affected by the construction of the new sewer pipe and will be unavailable for public use for approximately six weeks. Athletic events for this field will be rescheduled and relocated to other available locations throughout the City. One new personhole cover at the edge of this soccer field will be installed two feet under the playing turf to eliminate any possible tripping hazard. After construction is completed, only the 24-inch diameter personhole covers will be visible from the surface and no personhole structures will be installed inside any sports field. All existing landscapes and structures will be replaced in kind if disturbed or damaged by the construction. One Evergreen Pear tree and three Sycamore trees, all 2 inches and smaller in diameter, will be removed and replaced with one 36-inch box Evergreen Pear and three 24-inch box Sycamores. All other trees within the construction zone will be protected from damage by the construction in accordance with the City Standard Specifications. A temporary chain link fence surrounding the construction area will be erected during construction for the protection of park users and will remain in place during the grow in period of the new sod. No above ground improvements are proposed in this project. RESOURCE IMPACT Funds for this project are included in the FY 98-99 Utilities Department Wastewater CIP budget. The engineer’s esfilnate for this project is $502,005. POLICY IMPLICATIONS This report does not represent any change to existing City policies.
