complaints about construction noise. The Disfurbance Coordinator would determine the cause of the noise oomplaint (e.g., starting too early, bad muffler, etc.) and institute r�asonable measures to correc# the problem. Conspicuously post a telephone number #or the Disturbance Coordinator at the constructior� site and include it in the notice sent to neighbors regarding tt�e construction schedule. (The project sponsor could be responsible for designating a Noise Disturbance Coordinator, pasting the phone number, and pro�iding construction schedule notices; the Noise Disturba�ce Coordinator wauld work directly wi#h an assigned City staff member. Alternatively, the Noise Disturbance Coord'[nator could be ernployed by the City and funded by the applicant.} � Tsmporary Closure or Relacation of Child Care Center. If the project constructian sequencing �esu�ts in majar outdoor constr�ction activities occurring adjacent ta the child care center after it is in operation, then the project spansor, ai its option, shaal either temporarily close or relocate the child care center. Finding: Implementation of Mitigation 13-2 wvuld reduce canstructian noise impacts, but because this project likely would be constructed in phases o�er a long period af time, nearby sensitive receptors woufd be subjected to repeated construction noise, ther�by resulting in a significanf unavoidable constructiori noise impact. Facts in Support of Fir�ding: Implementation of Mitigation 13-2 wvuld reduce project- facifitated demolition and construction noise to the maximum extent feasible by requiring rigorous, coordinated procedures, scheduling, and equipment standards. Howe�er, because the project is likely to be constructed in phases o�er severai years, this intermittent noise impact on nearby sensitive recep#ors (e.g., residences) is considered significant and unavoidable. These facts are described and quantified in Draft EIR chapter 13 (Noise) an pages 93-1 through �3-20, which is here�y incorparated by reference. Impact: Impact 13-3: Praject�Facilitated Groundbarne Vibration Levels. Project- facilitated demolition and construction acti�ities could generate substantial vibration (e.g., from potential piie driving) in the project�icinity. Mitigation: Mitigation 13-3. Reduce groundborne vibration levels during individual, location- specific future project demolition ar�d construction periads by incorporating conditions in indi�idual pro�ect demolition and construction contractor agreements that stipulate the fol�owing groun�borne vibratian abatement measures: � Restrict vibration-generating acti�ify to between the hours of 7:00 AM and 7:00 PM, Monday through Friday. Prohibit such acti�ity on weekends and holidays. ■ If pile driving is proposed, prepare a vibration st�dy. If the vibration study shaws that pile driving, incEuding mitigation such as pre-drilling of pile holes, woul� cause �ibration exceeding 0.5 incheslsec ppv for s#ructurally sound buildings designed ta modern engineering standards or 0.2 inches/sec for structurally sound buildings far whict� structural damage is a major conoern, then pile driving shall no# be conduc#ed.
