d. As a part of each development plan, the College will identify and eliminate all direct, untreated piped discharges into Lake Johanna and Little Lake Johanna as a part of the campus expansion plans. 10.9 Traffic and Parking Mitigations. The COLLEGE shall be required to confonn to and implement the following traffic and parking mitigations: a. Mitigation 1 is the signalization of the Fairview/ Lydia Avenue intersection. "I,he additional 2018 analysis indicates that this intersection operates at an acceptable LOS D during the a.m. and p.m. peak hours for cumulative traffc 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 traftic. 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: ■ Northwestern to pay for a Fairview/ Lydia Avenue intersection improvement when it is warranted. A warrant analysis shall be completed as a part of the traftic study update required with each subsequent development phase. If subsequent City Council approved development occurs adding to the volume of traffic being projected for this intersection, before the signal is warranted. Conditions will be added to that approval requiring a proportionate cost share from that proposed development. b. 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 the frst phase of development. Development plans should provide additional information regarding the configuration of the westerly driveway at the intersection with Lydia Avenue, traffic routing through campus, and signage should be provided with the first development plan. :
