Home My WebLink AboutAgenda Report - July 21, 1982 (44)REGULAR CALENDAR Agenda item K-1 - "Approve 4 -way stop, Stockton and Pine Street" was introduced by Public Works Director Ronsko. Mr. Ronsko apprised the Counci! that the Public Works Department has reviewed the intersection as part of its ongoing program to reduce high accident 'locations. Any one of the following conditions may indicate the need for a four-way stop sign installation: 1. where traffic signals are warranted and `.h- need is urgent, the four-way stop i�, an interim measure .:iat can be installed quickly to control traffic while arrangements are being rtkde for the signal installation. 2. An accident problem, as indicated by five or more reported accidents of a type susceptible of correction by a four-way stop installation in a 12 -month period. Types of accidents susceptible of correction s.nclude right angle and left turn collisions. 3. Minimum volume warrant: a. The total vehicular volume entering the intersection from all approaches must average at least 500 vehicles per hour for any eight hours of an average day, and b. The combined vehicular and pedestrian volume from the minor street or highway must average at least 200 units per hour for the same eight hours with ani average delay to minor street vehicular trr.Ffic of at least 30 seconds per vehicle during the maximum hour. This intersection meets all three of the above. 1. The intersection has warranted traffic signals for sometime. A copy of the most scent investigations of the intersection for signals was presented for Council's perusal, however, preliminary review indicates that it's probably No. 5 in priority. If the City continues to install new signals at one intersection per year, the problem can only become worse in that time. 2. There have been five accidents in the last year and ten in the last f•o years which are of the type susceptible to correction, (i.e. right angle impact where one or the other or both vehicles failed to properly yield the right-of-way.) 3. The average of the highest 8 hours gives a total hourly traffic of 841 considerably above the minimum of 500 and the average of the highest 8 hours on the minor street 1- 267 vehicles per hour. People crossing Pine Street at this location will attest to the fact -that considerable :?-:;_ay is encountereu and may, in fact, increase the possibility of accidents because of the frustration level that sometimes develops. The City has previously prohibited some curb parking to provide visibility for drivers entering or crossing Pine Street. The installation of four-way stop signs at the intersection will enable the City to converl'_ a portion of these blocks to on - street parking. In order to reduce accidents and based on the established guidelines, it is the Public Works Department's recommendation that a four-way stop sign he installed at Pine and :.tockton Streets. A very lengthy discussion followed with questions being directed to Staff. CoL_acilman Pinkerton then moved to deny Staff's recommendation for approval of the installation of four-way stop signs at the intersection of Stockton and Pine Streots and eliminate a portion of she red curb on Pine Street at the same locat.icn. The motion failed to carry by the following tie vote: Ayes: Council Member- Pinkerton and Reid Noes: Council Member- Olson and Snider Absent: Council Member - Murphy Additicnal discussion followed and Council indicated it was desirous of having an opportunity te-, review the 1982 Traffic Signal Priority SCu<iy just received, before the matter is brought back to the Council.
