6.1 E Page 14 PROPOSEP WOt2K PROGRnA1, SCF[EA4LE AND Qi!DGF..T FOR TFIE PHESEItVE AT RF.UWOOD SHORL•'S 17AHCk{ 20P7 • Assess short-ternr rvnstructron i�upacts. Noise impacts from construc;t.ion within the project site wil] be analyzed based on the available project-specific construction infc�rmation provided to LSA. 'fhe Emrironmental Protection /�gency(EPA)recommended noise emission lcvels will bc used for the construction equipnlent. The constn.iction noise impact wilt be evaluated in terms of maximum ievels{I�,,,�x)and/or hnurly equivatent continuous nc>ise levels(I.e�) and their freq��ency of occut-rence. Analysis requirements will be based on the sensitivity of development within the vicinity of the site and.Redwood City noise re�;ulations. • Calculate�r�ject und cumulutive nErisc�i»zpacts. N<�ise impacts fi-om praject s�ecifc and cumu- lative vehicu3a.r traffic trips will be�ssessed using the t1.S. Federal fiigl�way 7�raffic Noise Pre- diction Model{FI-iWA-RI)-77-10�, Decemb�r 1978). Model input data include average daily traffic Ievels,day/night percenta�es of autos, medium and heavy trucks, vehicle speeds, ground attenuation factors; anci roadway widths.Proiectians of the future Community Noise Enuivalent Level(CNEL)alorig seIected roadway segments,hased on the tra£fic study prepared for the EIIZ, wilt be provided in a table fonnat to show the distance/contaur relationship.Noise impacts on sensitive land uses from traffic will be assessed. • Identify aircraft noise in:pacts. Noise impacts from aircraft opera#ions associated with the San Carlos flirport and possibly San Francisco International Airport on sensitive land uses within the �ro�ect site will be assessed.Praposed land uses will be evaluated far consistency with the Airport Land Use Plan where applicabie. • Id�ntif'y mitigativn measures. Mitigation measures designed to reduce short-and long-term noise levels to acceptable tevels wilt be identifed where necessary.Both an evaluation of the potential mitigation measures and a discussion of their effectiveness will be provided. 10. Air Quality a. Issues. Development activity associated with the project could potentially increase emission concentrations in the area through increased vehicle trips and constxuction.7'his increase could COi1il'i�Ull2e to e�isting air po�lc�tior, in the San Francisco air�asin. C',OTlS�I'i1CtiOT1 BCtIV1tIeS��SOCIr1tE(�i with develo�ment,including demolition,grading and ground disiurbarice,cot�id increase concen- trations of particulate matter.Increased air pollution could affect coznpliance with existing air quality plans and adversely affect the health of sensitive receptors. b. Approach.To identify existing air quality condi#ions and potential air quality impacts resulting froin the propased project,I,St�will undertal<e the fallowing subtasks: • Descrihe the existing regulatory fi�an�ework. The existing regalatory frame:work for air quality, includizig existing air quality laws and regulations and the roles of the local agencics including the California Air F2esources Board(ARB), the Bay Area Air Quality Management District (B.AAQMD).and Redwood C'ity will be c3escribed. • Obtain arid describe ttir quality�rTOir.iloring data. Project setting mcteorologica] and air quality data developed tlu-ou�h the California Air Resources Board(ARB)and climatolo�icat and air quality profile data gathered by t.he BA,AQMD wilt be used for the description of existing ambient air quality. Most recent published air quality data from locat air quality monitoring stations for the past three years wiil be included to help highlight existing air quality in the vicinity of the project site. Other sources such as regulatary doeuments,pr�fessional publieations, and past LSA experience in the project area may su�pletnent background infonnatican.
