ABSTRACT
Locating gas, electrical, and telephone utilities in the street right-of-way, but to one side of the street paving, has the advantages of minimizing the disruption of traffic, and reducing the costs of excavation and repaving when repairs are needed. In high-density urban areas where there are many utility lines, it is desirable to build underground galleries where the lines can be placed on racks, rather than burying each line in the soil. Transformers for electrical service may be in underground vaults, which must be drained and vented, instead of on utility poles. Telephone service installation requirements are not nearly as demanding as are many other utility systems, and they generally place no significant restraints on residential development. There are a number of issues concerning utility installation that from time to time come to the attention of subdivision designers and developers, and city engineers and planners.
