Goal NOI-3

Goal NOI-3:

Historic structures are not exposed to unacceptable vibration levels.

Policy NOI-3.1: Require vibration analysis for historic structure protection.

Prior to issuance of grading permits for any development project that is located within 150 feet of a historic structure and, if construction activities will require either: (1) pile driving within 150 feet; or (2) utilization of mobile construction equipment within 50 feet of the historic structure, the property owner/developer shall retain an acoustical engineer to conduct a vibration analysis for potential impacts from construction-related vibration impacts onto the historic structure. The vibration analysis shall determine the vibration levels created by construction activities at the historic structure, and if necessary, develop mitigation to reduce the vibration levels to within Caltrans threshold of 0.12 inches per second PPV for historic buildings
