Document Description
The project involves the construction and operation of a new earthquake observatory in a remote, undeveloped area of Acton. A conditional use permit (CUP) is required for observatories in the A-2 (Heavy Agricultural) zone by the Los Angeles County Code. The purpose of this facility is to measure earth movements and test instruments used in measuring earthquake activity. Scientists from the applicant's company (kinemetrics) will visit the site on an as-needed basis to retrieve tested instruments and deposit new ones. The observatory facility will not open to the public. The facility will involve the construction of a 40-foot-by-80-foot underground vault structure, approximately 10 feet below ground, consisting of eight sub-vaults, which will be used for testing seismic instruments.
