<br />I <br /> <br />" <br /> <br />..a ,...... ~ <br />.!.~ ""1 <br /> <br />DISTRIBUTION SYSTEM <br /> <br />67 <br /> <br />! <br />I <br />I <br /> <br />The Santa Monica feeder will supply the cities of Glendale, Bur- <br />bank, Los Angeles, Beverly Hills, and Santa Monica, Since this <br />feeder has no equalizing reservoir it was designed in a series of <br />level pressUl'e belts which would be a limiting condition for no <br />demand. For maximum demand the sizes were selected for graded <br />flow starting with 79 c,f.s. at the west portal of San Rafael No.2 <br />tunnel and delivering 30 c,f,s, to the City of Santa Monica. The <br />portion of this feeder between the San Rafael and Hollywood tun- <br />nels is protected by the Arroyo Seco spillway: the Hollywood tunnel <br />spillway protects the next section down to the Beverly Hills delivery; <br />and the remainder of the line is guarded by pressure-reducing <br />valves backed up by pressure relief valves. The pressure-reducing <br />and the relief valves will insUl'e against an undesirable rise of <br />pressure in thc pipe liue through the valuable and highly developed <br />residential areas of B~verly Hills, Hollywood, and Santa Monica. <br />However, a failure of mechanical equipment is always a possibility, <br />and therefore the pipe line has been provided with an ample factor <br />of safety to meet such a contingency. <br />As stated in the history and first annual report for the period <br />ending .June 30, 1938, the Lake Mathews dam and dike were then <br />completed, the upper feedel' pipe line and tnnnels were nearing <br />completion, and work was in progress on the head works and on <br />the Palos Verdes fceder from Eagle Rock Canyon, the first of the <br />supply lines to member cities to be built, The work accomplished..., <br />during the two years ending June 30, 1940 is briefly described in <br />the following pages. <br /> <br />Lnkc M atll e1V8 <br />, _ _ _ _ _Construction oLthe dam_and appudenant wDrks_wasJinished,on _ _ ___ <br />February 11, 1938. Approval of the construction by the state <br />engineer's office, as required by California law, was granted on <br />November 25, 1998 and a certificate issued accordingly, <br />A small District force has been engaged since June 30, 19:~8 on <br />miscellaneous work in the reservoir area. Trees, brush, and weeds <br />have been e1eaned up, windl'owed, and burned. A cottage for the <br />operator was moved from the Lakeview substation on the construc- <br />tion power system, reconditioned, and set up above the west end <br />of the dike and a house was reconditioned for a patrolman. A <br />garage aud a boathouse were built and a motor boat purchased for <br />use on the lake, A water system, for domestic use and sprinkling <br />of plants and ornamental trees, and power and telephone facilities <br />were installed. Protective growth was planted on the north slope <br /> <br /> <br />i <br />1\ <br />
