CITY OF REDWOOD CITY 6.1.A. - Page 15 <br /> BROADWAY PLAZA MIXED-USE PROJECT EIR <br /> E X H I B I T A: S C O P E O F WORK AND COSTS <br /> ▪ Air Quality and Greenhouse Gas Emissions. PlaceWorks will evaluate air quality and <br /> GHG impacts for construction and operational activities associated with the <br /> proposed Project.The air quality analysis will be based on the current methodology <br /> of the Bay Area Air Quality Management District(BAAQMD)for projects in the San <br /> Francisco Bay Area Air Basin (SFBAAB) using BAAQMD's most recently approved <br /> computer model,California Emissions Estimator Model(CaIEEMod). <br /> • Construction Phase. PlaceWorks will estimate short-term emissions generated <br /> from construction activities based on the construction schedule, duration of <br /> individual construction subphases, preliminary list of construction equipment for <br /> each construction subphase,an estimate of demolition debris, and an estimate of <br /> soil import/export,as provided by the project applicant and/or City.A Health Risk <br /> Assessment (HRA) for construction activities will be prepared to evaluate the <br /> concentration of toxic air contaminants and PM25 generated at the nearest off- <br /> site sensitive receptor. Dispersion modeling will be performed using a BAAQMD- <br /> accepted computer-based model(e.g. ISCST3/AERMOD). Cancer and toxicity data <br /> published by Cal-EPA will be used to estimate long-term and short-term (acute) <br /> health risks for offsite sensitive receptors.Air quality-related construction impacts <br /> will be compared to the applicable BAAQMD regional significance thresholds. <br /> Mitigation measures will be recommended to reduce short-term construction <br /> impacts,as necessary. <br /> • Operational Phase. The existing retail uses on the project site generate emissions <br /> from transportation sources, area sources (e.g., landscaping fuel, architectural <br /> coatings, consumer products), and energy sources (e.g., natural gas, electricity), <br /> and indirectly from water use, wastewater generation, and solid waste <br /> generation.The proposed project would result in an increase in these sources of <br /> emissions from new residential, office,and retail land uses.Operational phase air <br /> quality and GHG emissions will be compared to BAAQMD's significance <br /> thresholds. PlaceWorks will discuss consistency with BAAQMD's air quality <br /> management plan to attain the National and California Ambient Air Quality <br /> Standards (AAQS). PlaceWorks will qualitatively describe CO hotspots and odor <br /> impacts. For GHG emissions,a consistency analysis with applicable GHG reduction <br /> plans will include Redwood City's Climate Action Plan,the California Air Resources <br /> Board's (CARB) Scoping Plan for statewide GHG reduction goals of Assembly Bill <br /> (AB) 32, and the Association of Bay Area Government's/Metropolitan <br /> Transportation Commission's Sustainable Communities Strategy (Plan Bay Area) <br /> for the regional GHG reduction goals of Senate Bill(SB)375. <br /> is Biological Resources. It appears that biological resources do not pose a significant <br /> constraint to redevelopment of the site. PlaceWorks will collect and review existing <br /> information on biotic resources in the project site vicinity.The regulatory framework <br /> for biological resources will address federal, State, and local plans, laws, and <br /> regulations, including the Endangered Species Acts and the Clean Water Act. As <br /> appropriate,mitigation will be recommended. <br /> ✓ Cultural Resources. PlaceWorks will evaluate the potential for cultural resources, <br /> including historical, archaeological, and paleontological resources, unique geologic <br /> features as well as for human remains on the project site. This scope of work <br /> assumes that City staff will conduct the tribal consultation required by AB 52. <br /> PLACEWORKS 3 <br /> ATTY/AG R.2016.251/Placeworks AUGUST 31,2016 <br />
