Men Working on Street Drain

The Public Works Department is responsible for major capital projects as well as maintenance, inspection, and review of construction and repairs associated with the Town of Los Altos Hills’ municipal infrastructure. The Department is headed by the Public Works Director/City Engineer, who reports directly to the City Manager.

The department provides support for private development projects, code enforcement issues, Town events, review and response of resident requests, management of the Town’s capital improvement projects, and oversight and maintenance of the Town’s infrastructure and assets. On a day-to-day basis, the Public Works Department staff provide technical support to residents, contractors, consultants, other Town departments, and boards and agencies related to the Town's standards, processes, regulations, and codes related to private land development projects, work in the public right-of-way, and Town's infrastructure and assets. Some of the typical responsibilities of the Public Works Department includes oversight of capital improvement projects and improvements and maintenance of the Town’s sanitary sewers, storm drainage systems, roads, pathways, parks, and other facilities. The Department also facilitates and coordinates the procurement process to successfully deliver many public projects efficiently and cost effectively.

The Engineering staff are available to answer questions on storm drainage, sanitary sewer and other land development issues, in addition to performing technical reviews for site plans and subdivision plans. We pride ourselves in providing Los Altos Hills residents with the highest quality customer service, with integrity, and utmost professionalism.
