Initial Study—LID Annexation proposed golf course. To reach the new substation,the tie-in line will have to cross Old River. From the substation, power will be distributed to customers via a 21-kV distribution system. Since the PG&E transmission facilities are closer to the project site,any interconnection from WAPA lines(and the high cost of transmission tie-in line), were eliminated from further study. As mentioned above,Alternative 2, interconnecting to the Manteca-Kasson line is the preferred alternative, due to its close proximity to the project site and its connection to the Tesla station west of Tracy, which allows the best flexibility of procuring power supplies throughout the State. Additionally,existing PG&E distribution lines extend into LID's service boundary from two locations; Paradise Road and Stewart Road. These existing lines have an estimated capacity of 2,100 kilowatts each. Since the River Islands project's phasing begins on Stewart Road, near Manthey Road,the initial interconnection and service meter to the PG&E system would be located along Stewart Road to serve two separate uses on the existing 234 acre LID site and then up to 600 new homes within River Islands Phase IA. As load requirements increase beyond the initial 600 homes,a new substation would be necessary as described above. As River Islands develops,new infrastructure would be extended throughout the Stewart Tract in underground trenches for distribution of electricity. Major transmission lines would be placed within open space if possible and along major arterial streets to minimize visual impact. Existing pole lines removed as urbanization of the Stewart Tract continues over the next 30 years. LID would operate and maintain the distribution utility. Operation includes monitoring and inspection of the system by LID troublemen,switching the system for reliable operation,and responding to electrical outages. Maintenance of a new underground electrical system consists primarily of cleaning servicing, and testing the system as required. Occasional replacement of older or failed equipment will be required as the system ages. LID will likely operate the system through contract(s)for operation based on a competitive process. LID may also choose to provide some services itself and outsource construction and emergency repairs of major equipment. Alternately, LID may choose to hire an operating company to fully operate the entire system for LID. Requirements for a service yard,employee training and hazardous material handling procedures will depend in part on the selection of the system operator. The location of an LID service yard will be determined in conjunction with the developers of River Islands,most likely be located within the Employment Center area of the project along with the proposed substation. There are two general types of facilities for a distribution utility. The first type is the distribution facilities themselves. The second type is the interconnection with the utility grid. The distribution facilities will be located within the boundaries of LID,while the location of the interconnection facilities will be determined in conjunction with the grid owner through negotiations once the LID service territory is established and a detailed service plan has been developed for the service territory. The initial grid interconnection and initial distribution facilities will be constructed during 2005. Distribution facilities will be extended as required by development in the LID service territory. The River Islands development(through mitigation measures required of the City of Lathrop)ensures that all electrical distribution service is provided by underground facilities. The limited facilities that exist in the proposed annexation area are all above ground. Therefore,all of the existing facilities will eventually be removed as part of the development of River Islands,and new underground facilities will be built to serve new developments. The existing facilities that will need to be removed are fed radially from a source to the south of the annexation area through a single connection to the grid along the south western edge of the annexation area. 14
