Septic to Gravity Sewer Conversion Project Final Initial Study/Mitigated Negative Declaration Hazards and Hazardous Materials HAZ-1: Traffic Control Plan. Prior to construction, the City of Santa Ana (or its contractor) shall prepare a Traffic Control Plan to ensure proper access to residences and businesses in the area by emergency vehicles during construction and to maintain traffic flow. The Traffic Control Plan shall be approved by the City of Santa Ana prior to any lane closures. Noise NOI-1: The Project construction and improvement plans will include the following requirements for construction activities: • Construction contracts must specify that all construction equipment, fixed or mobile, shall be equipped with properly operating and maintained mufflers and other state -required noise attenuation devices. A sign, legible at a distance of 50 feet, shall be posted at the Project construction site providing a contact name and a telephone numberwhere residents can inquire about the construction process and register complaints. This sign shall indicate the dates and duration of construction activities. In conjunction with this required posting, a noise disturbance coordinatorwill be identified to address any construction noise concerns received. The coordinator shall be responsible for responding to any local complaints about construction noise. When a complaint is received, the disturbance coordinator shall notify the City within 24 hours of the complaint and determine the cause of the noise complaint (starting too early, malfunctioning muffler, etc.) and shall implement reasonable measures to resolve the complaint, as deemed acceptable by the City. All signs posted at the construction site shall include the contact name and the telephone number for the noise disturbance coordinator. • Identification of construction noise reduction methods. These reduction methods may include shutting off idling equipment (5 minutes), installing temporary acoustic barriers around stationary construction noise sources, maximizing the distance between construction equipment staging areas and occupied residential areas, and using electric air compressors and similar power tools. • During construction, stationary construction equipment shall be placed such that emitted noise is directed away from sensitive noise receivers. • Per Section 18-314of the City's Municipal Code, construction shall be prohibited between the hours of 8:00 p.m. and 7:00 a.m. on weekdays or Saturday, or any time on Sunday or federal holidays NOI-2: In order to reduce construction noise, during the demolition, site preparation, trenching, painting and paving phases, a temporary noise barrier or enclosure should be positioned between Project construction and the residences in a manner that breaks the line of sight between the construction equipment and these residences to the extent feasible. The composition, length, height, and location of noise control barrier walls should be adequate to assure proper acoustical performance and withstand structural failure.
