That the Tustin City Council, at their maeting of August 3, 1981, place the Median Isla_nd modifications along Irvine Blvd. at the Mountain View and A Street intersections on a priority list for capital projects to be added to the 1981-82 Capital Improvement Budget subject to funds being available due to reduced costs of other capital projects scheduled in the 1981-82 fiscal year. Recently, staff installed some traffic control signs along Irvine Blvd. at the intersections of Mountain View and "A" St~-eets. These signs p~chibited U-turns and left turns at each of the intersections. Their instal lation was initiated bec~;~e of the la~k of protected left turn lanes within the n~dian islar~. These intersections are becoming a traffic hazard, as traffic volun~s increase, for motorists making left or U-turns. As a result of these sign installatic~, seaef has received many cc~plaints (9) frc~ businesses on the northerly side of Irvine Blvd. who have had their access blocked to motorists traveling eastbound on Irvine and desiring to turn left at either intersection into private driveways of the businesses. As a result of these ccmplaints, staff has removed the "No Left Turn" signs at each intersection. In order to eliminate this hazardous' condition and inconvenience to the businesses, it is suggested that protected left tu~-n lanes be installed within the ~edian islands at each intersection. These left turn lanes would require modification to the existing islands (see attached sketches) that ~re constructed by the County of Orange in 1966. There would be a minimal loss of dichondra area at each intersection and it appears that the Olive tree at Mountain View intersection could remain in place. The estimated cost for each intersection nDdification is as follows: Mountain View Street ..... $7,300.00 "A" Street 8 950 00 The 1981-82 Capital Budget does not include any funding for these projects. It is re~um,=nded that both of these projects be placed upon a p=iority list for capital projects to be added to the current 1981-82 Capital Improvement Budget in the event funds become available due to reduced costs of other Capital projects within the 1981-82 fiscal year.
