CITY OF COLTON ITEM #9 AGENDA REPORT FOR THE COUNCIL MEETING OF FEBRUARY 5, 2008 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: AMANDA RHINEHART, INTERIM PUBLIC WORKS DIRECTOR SUBJECT: ADOPT RESOLUTION AMENDING RESOLUTION NO. 2119 TO ADD THE PLACEMENT OF ALL WAY STOP SIGNS AT THE INTERSECTION OF 8TH STREET AND CITRUS STREET DATE: January 24, 2008 BACKGROUND: The State of California Vehicle Code allows the installation of traffic control devices if adopted by a City ordinance or a resolution. Installation of stop signs, as well as other traffic control devices, must be warranted under the guidelines established in the Manual on Uniform Traffic Control Devices. On October 10, 2007, city staff conducted a traffic engineering analysis of the intersection 8th Street at Citrus Street, and concluded that installation of stop signs on 8th Street approaching Citrus Street from the north and south is warranted under the Manual on Uniform Traffic Control Devices guidelines. ANALYSIS/DISCUSSION: At the intersection of 8th Street and Citrus Street, visibility is limited due to the existing roadway design curve and unique characteristics along North 8th Street. The location was reviewed by the City of Colton Traffic Safety Committee on October 11, 2007. A warrant analysis was performed for the intersection (Exhibit A). The intersection met the warrant standards because the restricted view indicates a need for a traffic control device by means of a STOP sign. Staff reviewed the option to stripe this area as a no parking zone so as to improve the line -of -sight for motorists. The maximum visibility for eastbound West Citrus Street motorists exiting onto North 8th Street is 200 feet for on -coming motorists traveling northbound on North 8th Street. According to the Caltrans Highway Design Manual, this is less than the required horizontal clearance of 250 feet of line -of -sight for a design speed of 35 mph. The sight distance becomes more restricted when vehicles are parked along North 8'h Street, especially if the parked vehicles are large commercial vehicles. Implementing a restriction of no parking north of and south of West Citrus Street, along southbound North 8h Street for a distance of 100 ft, would only obtain a line - of -sight adequate for a roadway design speed of 30 mph. Therefore, to create a safer traffic condition than currently exists staff recommends installation of stop signs on 8t' Street at Citrus Street from the north and south.
