Thompson, Public Works Director ATTACHMENTS: 1) 2) Resolution Intersection Improvement Layout RECOMMENDATION: 1) 4) 5) Open public hearing Receive Staff presentation and public comment Question Staff and the public Close public hearing and deliberate Adopt resolution approving installation of STOP signs on Dublin' Boulevard at Inspiration Drive FINANCIAL STATEMENT: The cost of installing STOP signs and pavement markings is approximately $3,000o Sufficient funds are budgeted in the Street Maintenance Operating Budget to cover this cost. DESCRIPTION: Public Works Staff has received requests from citizens and City Police Officers to install STOP signs on Dublin Boulevard at Inspiration Drive. The Inspiration Drive approach at this intersection is controlled by a STOP sign, while traffic on Dublin Boulevard is uncontrolled. The Valley Christian School, located at 7500 Inspiration Drive, generates a significant amount of traffic on this street as parents drive to the school to drop off their children in the morning and pick them up in the afternoon. The concern is that, during these periods of heavy traffic on Inspiration Drive, a potential exists for right-angle collisions involving left-turning vehicles from Inspiration Drive and speeding through vehicles on westbound Dublin Boulevard. In response to these requests, City Staff conducted a STOP sign analysis to determine if three-way STOP sign control is warranted at this T-intersection. The analysis was based on guidelines and methodologies described in the Califomia Department of Transportation (Caltrans) Traffic Manual. Review of recent accident history, as well as newly collected traffic counts, were included in the STOP sign warrant analysis for this intersection. In addition, Engineering Staff supplemented the analysis work withfield observations of traffic conditions at this location during the morning and afternoon peak periods. COPIES TO: Roger Mahany, Christian Valley Center ITEM NO. __~ g:\agenmisc\dublin-inspiration stop signs Based on Staff's review of accident records, no traffic accidents have been reported at this intersection within the last 12 months. However, based on the analysis of traffic volumes and field observations, it was determined that a three-way STOP sign control is warranted at this intersection. This traffic control upgrade would enhance traffic safety at this location by helping to prevent right-angle collisions. The westbound right-turn movement from Dublin Boulevard onto Inspiration Drive is a very heavy traffic movement during the morning and afternoon peak periods due to parents driving to the Valley Christian School to drop off or pick up their children. In order to preserve the continuous flow of this movement without unnecessary interruptions, it is proposed to re-stripe the intersection to allow for a free westbound right-turn lane, as shown on the attached Intersection Improvement Layout. The proposed design would require all traffic to stop at this intersection, except for the westbound right-turn movement. The bulk of traffic entering this intersection is related to trips made by parents to and from the Valley Christian School. For example, during the moming peak hour (7:00 to 8:00 a.m.), approximately 550 vehicles make a right turn onto Inspiration Drive (going to school), while 460 vehicles make a left turn from Inspiration Drive (returning from school). Through traffic on Dublin Boulevard entering the intersection during this period only consists of approximately 105 eastbound vehicles and 35 westbound vehicles. At this low level of through traffic demand, no significant backups would be created at the proposed STOP signs on Dublin Boulevard. Likewise, no significant backups would occur during the evening peak hour of traffic on Dublin Boulevard (5:00 to 6:00 p.m.), as through traffic volumes only consist of approximately 45 vehicles in the eastbound direction and 200 vehicles in the westbound direction of travel. Notice regarding the proposed STOP signs has been sent to Califomia Highlands residents, as well as to the Valley Christian Center. Staff recommends that the City Council adopt the resolution approving installation of STOP signs on Dublin Boulevard at Inspiration Drive.
