Mitigation Measure 4.D-la: Commerce Drive at Johnson Drive Intersection.Prior to the granting of a certificate of occupancy for the first use in Phase I that would generate 100 or more PM or Saturday peak-hour trips,the City shall install or require the developer in Phase Ito install a traffic signal and construct a southbound left-turn lane to Commerce Drive at the Commerce Drive and Johnson Drive intersection.A funding mechanism for this improvement shall be approved by the City prior to the issuance of the first building permit for a Phase 1 use that would generate 100 or more PM peak-hour trips. Mitigation Measure 4.D-lb: Johnson Drive at Owens Drive(North)Intersection.Prior to the granting of a certificate of occupancy for the first use in Phase I that would generate 100 or more PM or Saturday peak-hour trips,the City shall install or require the developer in Phase Ito install a traffic signal at the Johnson Drive at Owens Drive(North)intersection.A funding mechanism for this improvement shall be approved by the City prior to the issuance of the first building permit for a Phase I use that would generate 100 or more PM peak-hour trips. Mitigation Measure 4.D-lc: Johnson Drive at Stoneridge Drive Intersection.Prior to the granting of a certificate of occupancy for the first use in Phase I that would generate 100 or more PM or Saturday peak-hour trips,the City shall ensure the implementation of the following improvements: I. Construct a third eastbound left-turn lane from Stoneridge Drive to Johnson Drive in conjunction with an additional northbound receiving lane on Johnson Drive(north side of intersection). 2. Construct an additional southbound right-turn lane on Johnson Drive. 3. Rebuild Johnson Drive as a six lane facility with three or four southbound lanes and three northbound receiving lanes for a minimum of 700 feet north of Stoneridge Drive.This improvement would require widening of Johnson Drive north of Stoneridge Drive by up to 36 feet and widening of Johnson Drive south of Stoneridge Drive a commensurate amount to align travel movements through the intersection. A funding mechanism for these improvements shall be approved by the City prior to the issuance of the first building permit for a Phase I use that would generate 100 or more PM peak-hour trips. Mitigation Measure 4.D-1d: Stoneridge Drive Queue Spillback(Stoneridge Drive and Johnson Drive Improvements). Prior to the granting of a certificate of occupancy for the first use in Phase I that would generate 100 or more PM or Saturday peak-hour trips,the City shall ensure the implementation the following improvements: 1. Modify the Stoneridge Drive at Northbound I-680 off-ramp to provide a northbound right-turn overlap phase. 2. Construct a second southbound left-turn lane from Johnson Drive to Stoneridge Drive. 3. Extend the existing westbound right-turn pocket at the Johnson Drive and Stoneridge Drive intersection approximately 800 feet east by widening Stoneridge Drive and convert the resulting lane into a through- right-shared lane. Install lane markings in the curb lane and adjacent lane indicating I-680 Northbound Only to reduce lane changes between Johnson Drive and the northbound on-ramp. 4. Construct a second on-ramp lane to northbound 1-680 from the westbound Stoneridge Drive approach. The two lane on-ramp should be merged to one lane prior to the freeway merge area.The lane drop will occur over a distance of at least 800 feet, and will require reconstruction and widening of the bridge at this on-ramp from one to two lanes, with the merge occurring after the bridge. (Note: This improvement is within Caltrans right-of-way and requires Caltrans design review and oversight.) A funding mechanism for these improvements shall be approved by the City prior to the issuance of the first building permit for a Phase I use that would generate 100 or more PM or Saturday peak-hour trips.
