The SMP also ex�fains that site conditians do no# pre�lude any of the uses proposed, but that further risk assessment is required wnen the precise on-s+te locations and details af sensikive uses such as chifd ca�e, medical clinics, and recreatian areas are identified, so that any mitigation measures specific to the operations of such uses will be identifed and implemented. Pending completion of the required suppleinenta! risk assessments and identi�cation af ineasures to ensure compliance with residen#ial-levef ESLs �#or tf�ese sensitive uses, the proposed projecYs impacts during operations from {�atential exposure to existir�g groundwater and soil vapor con#amination are assumed to represent a pofenfrally sigrrificant impact. Mitigation: Mitigation 12-�1. The applicant shall implement the Site Managemen# Plan {5MP} attached as an appendix to the Draft EIR. At such times as the exact locations and details of sensitive uses such as child care, medical cl9nics, and publicly accessible open space are identified, the applicant shall supplement the SMP to assess any risks to those uses from existing hazardous materials o� the development site and shall identify any treatment measures required to ensure that rfs�CS ta users r�main below regulatory limits. Finding: implementation of Mitigation 12-1 would reduce the potential impact of project- related exposure to existing soil and groundwater contaminatian to a less-than- sign�cant level. Facts in Support of Finding: Implementation of Mitigation 12-1 would ensure that khe Site Management Plan (SMP} inc�uded in Draft EIR appendix 21.6, as well as a Health and Safety Plan (HASP), are irnplemented during all project construction. Furthermore, once the precise lacations and operations of propased sensitive receptors—such as child care, medical clinics, and recreation--have been determined, additionaf investigations would be required ta evaluate the presence and levels of any graundwater or soil vapor contamination, pursuant to applicable regulatory requirements. The mitigation for sensitive uses must meet residential screening criteria as defined by the appropriate regulafory agencies {e.g., RWQCB, DTSC, SMCHSA, BAAQMD, CaIOSHA}, These facts are described in Draft EIR chapter �2 {Hazards and Hazardaus Materials) an pages 12-9 though 12-24, and appendix 21,6 (Site Management Plan}, which are hereby incorporated by reference. Noise Impact: Impact 13-1: Potential Exposure of Proposed Child Cars Faci#ity to Noise Ler�els Exceeding Standards. The Precise Plan includes a pro�isian for a proposed child care center. The center's children, employees, and r►isitors could be exposed to vari�us existing and projected noise saurces, inclucfing U.S. 101 traffic, The compatibiiity of the child care land use with the existing aRd projec#ed noise environment has been evafuated based on the Redwood City Noise Guidelines far Land Use Pl�nning {see Draft EIR Table 13.4). New educational (e.g., child care} de�elopment is considered "satisfactory" in noise envi�onments of less than 55 dBA CNEL.
