Jeff Knowles, Deputy Director of Transportation, believed it would be 25 feet per car and approximately 100 vehicles. Mr. Brozosky wondered if there would be sufficient room for the traffic to back up to the side of the school if the roundabouts remained as opposed to Vineyard Avenue. Ms. McGovern was trying to decide how Vineyard Avenue was designed based on how the General Plan defined different types of roadways. Mr. Wilson said the Specific Plan called for Vineyard Avenue to be designed as a rural street. Ms. McGovern referred to the staff report for item 6b(2), which stated that although Vineyard Avenue from Bernal Avenue to Isabel is designated as a thoroughfare in the General Plan. She asked staff for the definition of a thoroughfare. Mr. Knowles said there was no definition for a thoroughfare and it was a problem during staff's presentation of the Vineyard Avenue Traffic Calming Plan. Ms. McGovern pointed out that the word "thoroughfare" was used throughout the staff report. To move Vineyard Avenue to the designation of a rural street, she asked what type of traffic is expected per hour on a rural street. Mr. Wilson noted the designation of Vineyard Avenue was a rural street in the Specific Plan, which was conducted after the General Plan was adopted. The Specific Plan stated that Vineyard Avenue should be designed to be a rural type street and it went further with the terms of the definition, which is related to the width and how many lanes it consisted of and the general nature of the street. Ms. McGovern asked what type of traffic is expected per hour because when she reviews the General Plan it measures it by what the traffic is predicted per hour. Mr. Wilson said the rural street designation has more to do with how it fits the environment and the number of lanes controls the traffic. In this case, Vineyard Avenue is two- lanes which controls the amount of traffic that would be on the street. Ms. McGovern said she could not envision the City building Vineyard Avenue to be a rural street knowing that it connects Livermore and Pleasanton. Mr. Brozosky believed staff was describing Vineyard Avenue as an arterial road with a rural feel. Mr. Wilson said a two-lane arterial street could carry 850 cars per hour. Staff has placed limitations on the number of traffic volume by the traffic signal placed at Ruby Hill. Ms. McGovern believed Council could actually predict that 850 vehicles per hour could travel on Vineyard Avenue during non-peak traffic time. Mr. Knowles noted 850 vehicles per hour is out of the General Plan and it does not mean that the roadway could not physically carry more traffic, but for a two-lane arterial, staff Pleasanton City Council 13 10/18/05 Minutes
