This section documents the Existing (2010) Conditions in the study area. The discussion presented here <br />is limited to specific roadways, transit routes, and bikeways in the project's vicinity. <br />Existing Roadway Conditions <br />KOA conducted an updated field review for this project. Due to significant land use development in <br />recent years, there are some significant roadway and intersection improvements within the study area <br />that have changed since the original traffic study was conducted. Streets in the project vicinity that <br />could be affected by the proposed expansion project include Main Street, MacArthur Boulevard, Dyer <br />Road, Sandpointe Avenue, Sunflower Avenue, Imperial Promenade, and Red Hill Avenue. <br />Main Street <br />Main Street is a north -south arterial roadway in the project vicinity, located west of and adjacent to the <br />project site.
