ITEM #11 CITY OF COLTON AGENDA REPORT FOR THE COUNCIL MEETING OF AUGUST 1, 2006 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: AMER JAHKER, P.E., CITY ENGINEER SUBJECT: ADOPT RESOLUTION TO AMENDING RESOLUTION # 2119. TO ADD TWO STOP SIGNS ON LA CADENA TO MAKE THE INTERSECTION OF LA CADENA AND BARTON ROAD. DATE: July 24, 2006 BACKGROUND: On July 11, 2006, Public Works Department conducted a neighborhood meeting to address resident safety concerns at the intersection of La Cadena Drive and Barton Road. Barton Road and La Cadena Drive is a T intersection. Traffic traveling westbound on Barton Road experience extended delays due to the volume of traffic on La Cadena Drive during peak travel times. In addition, Barton Road does not intersect with La Cadena at a right angle. The City is currently in the process of installing a signal at the intersection. The signal will be in operation within 60 days. The State of California Vehicle Code allows the installation of traffic control devices, if adopted by a City ordinance or a resolution. Section 21 of City of Colton Resolution # 2119 lists through streets and stop intersections within the City of Colton. At the City's request, TEP, Inc. conducted a warrant analysis on July 25, 2006 and found that interim stop signs are warranted. ANALYSISIDISCUSSION: The intersection of La Cadena Drive and Barton Road does not intersect at a right angle. The intersection is heavily traveled, and traffic traveling westbound on Barton Road experience extended delays. The Public Works Department performed further analysis and study of the intersection. The Department found that the subject intersection met the AWSC vehicular volume warrants. The collision history had more than 5 reported crashes in a 12 -month period. The vehicular volume entering the intersection from (Major Street) La Cadena Drive averaged 1,137 vehicles per hour for an 8 hour period in a day. The (minor street) Barton Road averaged 233 vehicles per hour for an 8 hour period in a day and the 85`h -percentile approach speed of the major traffic is 53 mph. As mentioned, the City is in the process of designing and installing traffic signal at this intersection. Thus, the multi way stop is an interim measure before the installation of the traffic control signal. ORANGE\MMARTIN EZ\28648.1
