SEVENTEENllt STREET AND YORBA Sll~EET (SOUllt)/CA~RROLL WAY INTERSECTION
RECOMMENDATION:
For the City Council meeting of December 1, 1986.
Authorize staff to proceed with the intersection modifications to provide dual
left turn lanes from northbound Yorba to westbound .Seventeenth Street and
coordinate said work with the proposed A.H.F.P. project along Seventeenth Street,
'and authorize a supplemental budget appropriation in the amount of $6,325.00.
BACKGROUND:
The City Council had requested staff to review the intersection of Seventeenth
Street at Yorba Street (south)/Carroll Way with respect to left turn movements
from northbound Yorba Street to westbound Seventeenth Street. The major concern
was the extensive number of 1.eft turn movement§ with respect to the limited
storage capacity of the protected left turn lane, and the limited cycle time for
said left turn movements.
DISCUSSION:
The intersection review indicates that dual left lanes can be accommodated on the
southerly leg of Yorba Street, which would almost double the left turn capacity
for that movement. This modification can be accomplished by minor modifications:
Estimated
Cost
Restriping and signing ......................... $ 2,000.00
° Replacement/addition of traffic signal detection loops .......................
° Modification of ~dian island on
westerly'leg of Seventeenth Street ...........
4,200.00
1,225.00
The City is 'ready to commence work along Seventeenth St. once the County Arterial
Highway Financing Program (A.H.F.P.) completes the review and approval of the
plans. It is estimated that approximately $2,200.00 of the above mentioned work
could be included within that project and funded 50% by the A.H.F.P. process.

In the event this work is coordinated with that project, the net modification cost
to the City could be reduced to $6,325.00.
Attached, is a schematic drawing of the modifications that are proposed for this
intersection.
