Description: Materials and Supplies Finance: Council Notes: Agenda Item No. CITY OF SAN BERNARDINO REQUEST FOR COUNCIL ACTION STAFF REPORT Subject: Resolution authorizing the installation of a 4-way stop at the intersection of 27th Street and Davidson Avenue. Background: Traffic Engineering staff received a request to evaluate the intersection of 27th Street and Davidson Avenue for a 4-way stop. The intersection is currently controlled by a 2-way stop (the north & southbound approaches to the intersection stop). The requestor was mainly concerned about the lack of controls, considering that elementary school children frequently cross 27th Street in an uncontrolled school crosswalk on the west leg of the intersection. Traffic Engineering Section staff evaluated the intersection in accordance with the criteria prescribed in the California Manual on Uniform Traffic Control Devices. The evaluation included a field inspection of the intersection and a review of traffic volumes and collision records. Based on the data gathered, and field observations, a 4-way stop at this intersection will improve right-of-way control and it will enhance vehicle/pedestrian safety. While this intersection fails to meet any of the standard warrants, engineering judgment was exercised with considerations for the substantial fulfillment of the minimum volume warrant, high-approach speeds on 27th Street and the presence of an uncontrolled school crosswalk on the west leg of the intersection that elementary school children use to cross 27th Street on their way to and from Davidson Elementary School. Based upon these overriding considerations, staff recommends the installation of a 4-way stop at this intersection. The attached Resolution includes existing stop signs that were approved on the approaches to both 27th Street and Davidson Avenue. The existing stop signs were previously approved under Resolution No. 2482. For consistency, it is recommended that the existing stop signs be included in the proposed amendment to Resolution No. 655. Financial Impact: Funds are appropriated in the Public Works Department budget, FY 10-11 budget account for materials and supplies (Account No. 001-400-5111-0000-0093). Account: 001-400-5111-0000-0093 Budgeted Amount: $255,000 Balance as of 02/10/11: $40,000 Balance after the approval of this item: $38,000 Please note, this balance does not indicate available funding. It does not include non- encumbered reoccurring expenses or expenses incurred but not yet processed. Recommendation: Adopt Resolution. 2 CITY OF SAN BERNARDINO REQUEST FOR COUNCIL ACTION STAFF REPORT - Continued Attachments: "1"—Map "2"—Warrants I 3 LOCATION OF PROPOSED 4-WAY STOP > 30TH ST 30TH ST a o C❑LIMA RD I COLRD > w r 29TH ST z ¢ � w Q 29TH ST J A ° Q Q z ❑D DR Q o > L5 Q W U z MIRAD RD j DA D J !7EZI E DAVIDSON Uj cy 28TH ST `n a ALEXANDER ST w EXANDER V Q 27TH ST 2 H ST 26TH ST Q pq 26TH T 5 o Lj o 26TH T 25TH ST A 25TH ST a 24TH T 5TH S a JV VICINITY MAP NO SCALE J CITY OF SAN BERNARDINO DEPARTMENT OF PUBLIC WORKS Proposed 4-Way Stop: Be San rnae loll ENGINEERING SECTION n 27th Street @ Davidson Avenue Created by: Tony Lugo Date: 2/14/11 CITY/COUNTY/TOWNSHIP OF: ALL-WAY—STOP WARRANT N INTERSECTION: � � ��'- C� `_L-��t� '"-''�� If any one of the conditions (1,2,3 or 4) listed below is met and the volume of traffic on the intersecting streets should be approximately equal (5), the intersection may warrant an all-way stop sign installation. Other criteria may also be considered per MUTCD, however, the final determination should be based upon engineering judgment. SATISFIED 1 Where a traffic signal is warranted and recommended, and the need is urgent, the all-way stop is an interim measure that can be installed if appropriate. ❑ YESNO 2 A collision pattern exists as indicated by 5 or more reported collisions (in a 12-month period) ❑ YES VNO of a type susceptible to correction* by an all-way stop installation. *These include right angle as well as right and left-turn collisions. Correctable collisions in a 12-month period: 3. Minimum volume: ❑ YES EYNO a. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours of an average day. 8 highest hours entering traffic: 4, Gat% 1 hour average: Criteria met: , YES❑ NO And b. The combined vehicular, pedestrian, and bicycle volume entering from the minor street (total of both approaches) averages 200 or more units per hour for the same 8 hours as in 3a., with an average delay to the minor street vehicular volume of at least 30 seconds per vehicle during the maximum hour. 8 hours combined minor street volume and pedestrians: 4-2—oz- 1 hour average: i 5- J Average delay: /71 7 Criteria met: ❑ YES PINO But c. When the 85th percentile approach speed of the major street traffic exceeds 40 miles hour, the minimum vehicular volume warrant is 70%of the above values. 85th %: U . f:! 70% rule applies? J'YES ❑ NO 4 Where no single criterion is satisfied, but where Criteria 2, 3a, and 3b are all satisfied to ❑ YES NO 80% of the minimum values. Criteria met: ❑ YES NO 24 hrs traffic volume on 7��5 : ,31y Su ort: The Volume ratio should 5. be approximately 1:1 indicating that ❑ YES VNO 24 hrs traffic volume on �,�r;�s�,.� �:/871 Volume Ratio: traffic volumes on the major & minor Streets are approximately equal. The All-way stop warrant is met if any one of conditions 1,2, 3 or 4 is met and condition 5 should WARRANTED? also be satisfied. If engineering judgment prevails, it should be noted in the comments below. '0 YES ❑ NO Option: Other criteria that may be considered: If visibility cannot otherwise be addressed, there is a need to control vehicle-pedestrian conflicts (or bicycle) near high pedestrian/bicycle generators, left- turn or right-angle conflicts, or the traffic operation of an intersection of two residential streets of similar design and operational characteristics would be improved with an All-way stop.
