Raitt Street is a two-lane roadway facilitating travel between major arterials and ultimate destinations. • Bear Street is east of the project site. Bear Street is a four-lane arterial north of MacArthur Boulevard and a five-lane arterial south of MacArthur Boulevard. This north-south arterial provides access to State Route 73 to the south. • MacArthur Boulevard is south of the project site. MacArthur Boulevard is a six-lane east-west arterial that provides primary access to Jaguar Way and ultimately to the project site. This arterial provides regional east-west travel to the adjacent cities of Fountain Valley and Irvine. Adjacent School Circulation The primary entrance to the Church parking lot is accessed from the Raitt Street/Alton Avenue traffic signal. Traffic accesses the Church, the YMCA, and Segerstrom High School (one of the school’s access points is in this location) from the southern leg of Raitt Street. The Church holds services at 8:00 a.m. Monday, Wednesday, and Friday. Inbound trips for these services occur at the same time as inbound and drop-off trips for the high school. In order to understand how high school-generated traffic affects access, LSA staff conducted a field visit of the site on Wednesday, September 13, 2017. Raitt Street is used by some Segerstrom High School vehicular traffic as a drop-off area, although the street is not designated by the school for that purpose. During the morning drop-off, school traffic enters from Alton Avenue and many drivers seek to drop off students as close as possible to Alton Avenue. The curb in this area of the southerly projection of Raitt Street is painted red. California Vehicle Code Section 22500(c) states that a person shall not stop, park, or leave standing any vehicle whether attended or unattended in an area indicated by a sign or red paint on the curb so long as the sign or paint was erected or placed by local authorities pursuant to an ordinance. No signage is placed along Raitt Street indicating whether this is a “No Stopping” or a “No Parking” zone. Signage consistent with California Manual on Uniform Traffic Control Devices R26(S), R26A(S), or R28(S) would further support the red curb prohibition of stopping a vehicle in this area, but would not be necessary. As long as the red curb was placed by the City pursuant to an ordinance, drop-off activity would not be permitted in this area and vehicles could be cited. When vehicles stop on Raitt Street to drop off in this undesignated area, traffic flow on Raitt Street for the Church’s morning service is restricted. The southbound lane is 15.5 feet in width, which does not provide a comfortable parking and travel lane. As a result, vehicles traveling southbound slow considerably when passing stopped vehicles. Vehicles that dropped off rejoin the southbound traffic and make a U-turn at the southern end of Raitt Street. Occasionally drivers will choose to U-turn midblock rather than proceed to the end of Raitt Street. Northbound queues were not observed to 3-59
