The additional 2018 analysis indicates that this intersection operates at an acceptable LOS D during the a.m. and p.m. peak hours for cumulative traffic conditions. The LOS D delay threshold for an unsignalized intersection is 25-35 seconds; the LOS E delay threshold is 35-50 seconds. Based on this information the LOS D reported has no additional capacity available to support additional traffic. To address this, TKDA recommends that a traffic signal at Fairview Avenue and Lydia Avenue be installed. In order for a signal to be installed it must meet specific criteria (signal warrants). A cursory level review of the signal warrants (based solely on projected peak hour traffic volumes) indicate that the peak hour warrant 3B will be met under year 2018 cumulative conditions. Typically, the peak hour warrant alone will not justify the installation of a signal, additional analysis will be necessary. A signal is not included in the County or City's long range Capital Improvement Plan. Therefore funding has not been identified and there is no timeline for this improvement. Because the proposed college expansion uses up the additional capacity at this intersection, staff recommends that this mitigation measure reflect these limitations and be changed to an action item that would aid the implementation of the identified improvements. Staff recommends that a condition be added to the PUD requiring: 21 Northwestern to pay for a Fairview/ Lydia Avenue intersection improvement 22 when it is warranted. A warrant analysis shall be completed as a part of the traffic 23 study update required with each subsequent development phase. If subsequent 24 City Council approved development occurs adding to the volume of traffic being 25 projected for this intersection, before the signal is warranted. Conditions will be 26 added to that approval requiring a proportionate cost share from that proposed 27 28 29 30 31 development. 2. Mitigation 2 is to open the west gate at Lydia Avenue to outbound right turns and inbound left turns during the p.m. peak hour. This improvement should be included as a condition in the PUD and should be completed at the same time as 32 the first phase of development. Development plans should provide additional 33 information regarding the configuration of the westerly driveway at the 34 intersection with Lydia Avenue, traffic routing through campus, and signage 35 should be provided with the first development plan. 36 37 3. Mitigation 3 is the addition of an exclusive right turn lane at the College entrance. 38 This should be included as a condition in the PUD agreement. Due to existing 39 traffic, this improvement should be completed as a part of the first phase of 40 development. The intersection should be striped to include a southbound left turn 41 lane from Lydia to Lincoln Avenue. 42 43 44 45 PF07-002_RCA_082707 Page 7 of 9
