sites for Tai Wo Ping Class III licensed area and Wong Chuk Hang, Tin Wan Class II licensed areas was completed. This section is also responsible for the repair of rainstorm damage and the usual main- tenance of these areas. Expenditure on works in licensed areas during the year amounted to $533,270.
90. The section prepares quantities of material which are required for minor improvement works in squatter areas. The materials are generally supplied to the squatters by the Government and the actual works are undertaken by the squatters themselves. In some case, how- ever, where the work involved is beyond the technical capacity of the residents, the section carries it out.
91. The clearance and resettlement of squatters to make way for permanent development sometimes involves the clearance of patches of cultivation and this section is responsible for preparing accurate topographical surveys for ex-gratia crop compensation and disturbance allowance.
ELECTRICAL SECTION
92. The electrical section is responsible for the maintenance, altera- tion and improvement of all electrical installations in estates, factories and cottage areas, and also providing new electrical installations for other departments with maintenance offices in estates. Technical advice and inspection of tenants' electrical installations are also carried out in order to ensure that they are safe.
93. The improvement of living standards has led to a rapidly increasing demand for more electrical supplies in estates as tenants buy more electrical appliances. This extra loading has caused breakdowns in supply and it has therefore been necessary to carry out a programme for uprating the switch gear and rising mains in estate blocks. A total of 52 Mark III and Mark IV domestic blocks were uprated during the year, but it is still necessary to limit the electric loading in domestic rooms to normal domestic appliances. To increase the loading to cover heavy electrical appliances, such as air-conditioners, would require the installation of new main cables and a consequential increase in rent.
94. In order to improve and expedite repairs to electrical break- downs, two emergency standby teams were introduced to attend to breakdown calls from estates after office hours until 11.00 p.m. During the year, this section has installed 13 street lights in Ngau Tau Kok
