Conflict with adopted policies,plans,or ❑ ❑ ❑ � programs regarding public transit,bicycle,or pedestrian facilities,or otherwise decrease the performance or safety of such facilities? Traffic, Circulation and Access The transportation and traffic impacts related to the proposed modifications were evaluated based on the traffic studies prepared by Kittelson&Associates,Inc. (Kittelson&Associates,Inc. 2012a, 2012b) and the transportation impact analysis contained in the 2007 FEIR and 2007 Addendum No. 1 for the Redwood City Costco Wholesale and Tire Center.ICF and the City independently reviewed the information provided by Kittelson&Associates. Environmental Setting Roadway System The roadway system remains the same as described in the 2007 FEIR. Traffic Conditions To identify the traffic impacts related to the proposed modifications,existing(2012) traffic conditions were evaluated for intersections on Middlefield Road adjacent to the project site,which include the Middlefield Road/Woodside Road intersection,the Middlefield Road/Willow Street intersection,and the Middlefield Road/Charter Street intersection (study intersections).These three signalized intersections were identified as having the highest potential to be affected by the proposed modifications. Since the adoption of the 2007 FEIR,Costco has moved the project entrance at the Middlefield Road/Charter Street intersection to the Middlefield Road/Willow Street intersection and reconfigured and signalized the Middlefield Road/Willow Street intersection.Costco has also dechannelized Middlefield Road and increased the length of left-turn pocket at the Middlefield Road/Woodside Road intersection. Traffic Volumes Manual intersection traffic volume counts were conducted at the three study intersections for the weekday PM peak period (4 to 6 p.m.) on May 15,2012 and Saturday midday peak period (11 a.m.to 3 p.m.) on May 19,2012 while school was still in session;the traffic volume counts account for the full range of traffic demand experienced in the area under existing conditions. To provide context,the traffic counts from May 2012 were compared to other traffic counts collected in the study area over the past 6 years since the initial Costco onsite redevelopment project was considered.Table 4.3-1 provides a comparison of traffic volumes on Middlefield Road between 2006 and 2012.
