➢ Add signage to the northbound direction along with lane line extensions to direct the motorist in the left turn lane that they can enter the inner right -turn lane for access to the I-5 NB Ramp. The northbound left/thru lane should have signage and lane extensions to direct the motorist to use the outer right -turn lane for access to the I-5 NB Ramp. These improvements are subject to the review and approval of the City of Santa Ana. With the implementation of improvements, the queues are generally adequate under Year 2040 Buildout Plus Project traffic conditions during both the AM and PM peak hours. However, the southbound right -turn lane at Cabrillo Park Drive/4th Street may exceed the storage provided. As an alternative, subject to review and approval of City staff, an option southbound through/right lane in addition to the proposed southbound right -turn lane can be striped to provide additional queuing storage. The implementation of the recommended improvements also helps to improve congestion and limit unnecessary weaving/merging of vehicles that need to enter the I-5 NB Ramp. However, in the event that Fourth Street experiences "spikes" in congestion during the weekday AM and PM peak hours, residents will very likely re-route themselves (self -monitor) and utilize the northern Driveway on Park Court Place instead of the driveway on Fourth Street. The intersections of Cabrillo Park Drive/Park Court Place and Cabrillo Park Drive/Fourth Street have enough capacity to accommodate the additional trips. ■ Existing Plus Project Recommended Improvements — The following intersection improvements are recommended to mitigate the impacts of the proposed Project under these conditions. ➢ No. 13 — SR-55 SB Ramps at Fourth Street: Modify the eastbound shared through/right- turn lane to construct a free -right turn lane. Modify the existing traffic signal as necessary. This improvement is subject to the review and approval of the City of Santa Ana and Caltrans. Per City requirements, the Project may be expected to pay a fair-share/local fee to cover the Project's fair share of the full construction costs needed to implement these mitigation measures. ■ Year 2025 Cumulative Plus Project Recommended Improvements — The following intersection improvements are recommended to mitigate the impacts of the proposed Project under these conditions. ➢ No. 8 — I-5 NB Ramps at Fourth Street: Construct an additional westbound right -turn lane. Modify the existing traffic signal as necessary inclusive any modifications to the traffic signal phasing. This improvement is consistent with the Traffic Impact Study for the Metro East Overlay Zone in the City of Santa Ana. This improvement is subject to the review and approval of the City of Santa Ana and Caltrans. The proposed Project is expected to pay the full construction cost needed to implement these mitigation measures. ➢ No. 13 — SR-55 SB Ramps at Fourth Street: Modify the eastbound shared through/right- turn lane to construct a free -right turn lane. Modify the existing traffic signal as necessary.
