er I la • Additional modifications to signal heads would be needed for westbound left turn and westbound through traffic on Bernal Avenue at the SB ramps. The current signal heads align with the current geometry. It is likely that the left turn signal head indication on the mast arm would be relocated several feet to the north to align with the center of the two left turn lanes. In addition, the through lane signal head indication on the mast arm would be relocated to align with the center of the right - most through lane. • The traffic signal currently uses pavement loops for vehicle detection. The conversion of the left- most through lane to a left turn lane would require changes to the existing detection loops so that they are associated with the appropriate phase. • Given that nearly 1,000 vehicles would use the dual left turn pocket during the AM and PM peak hours under cumulative conditions, Caltrans may question the length that the two full receiving lanes • are provided for the southbound onramp. Under existing conditions, there are approximately 350 feet of two full lanes. This is most likely adequate, but depending on the results of the traffic operations report, it is possible that Caltrans could require roadway widening further south on the :: on -ramp. This will be investigated and discussed with Caltrans as a first phase of work. 1- As indicated, the development of the concept design will consider the specific issues cited above and will be developed based on collectively considering existing features, the existing available right of way, , coordination of above and below ground utilities, the circulation and installation of bicycle and pedestrian facilities and possible retaining walls requirements. Based on the review of existing information and the • assessment performed, BKF will develop geometric alternatives including vertical design information which address the assessment results and Project goals. As alternatives are developed, BKF will be careful to comply with the Caltrans' Highway Design Manual to minimize and /or avoid processing Design , Exception Fact Sheets. The geometric alternatives will be reviewed with the City to confirm that the City lit goals are met and establish a preferred alternative. - Peskin Exceptions — After City comments are incorporated for the geometric alternatives, BKF will prepare to meet with Caltrans to confirm their support of the Project and processing requirements. For the meeting, BKF will conduct a final review of the geometry and complete the Design Checklist (DIB78), to ensure that all mandatory and advisory design exceptions are identified. After meeting with Caltrans on concurrence of Project features and design exceptions, BKF will prepare Design Exception Fact Sheets a 4' for submission to Caltrans for review and approval. The scope of work accounts for the preparation and approval of four additional design exceptions. BKF would suggest that the Fact Sheets be submitted prior to the actual submittal of the PS &E in order to start the review process, which tends to take longer than PS &E review and approval. In this case, the issuance of the encroachment permit for the Project will not be delayed by the Fact Sheet approval and signature. a Geometric Exhibit Plans — The concept drawings developed for the geometric alternatives and Caltrans v. approval of the Project will be enhanced to create an exhibit which clearly demonstrates the Project s features. The exhibit will be presented to the community in a public forum. The exhibit will delineate pedestrian and bicycle facilities and roadway modifications. Right of way lines and roadways will be identified and typical cross sections will be added. Landscace Plan — The BKF Project Team will work with the City to create a landscape statement for the Project site and develop consensus on the desired landscape character for this key City gateway. Field reconnaissance will be conducted to obtain an inventory of existing trees (size, species, condition) and determine the character of adjacent streetscape / setting. The BKF Project Team will coordinate with City j`'; Staff to ascertain preferences in irrigation equipment and plant material and discuss the potential for a "Bay- Friendly" project. Based on this information, the BKF Project Team will prepare illustrative landscape plan and images of possible plant palettes. This will provided to the City for review and comment before it is completed for presentation at the public meeting. Public Meeting — Upon obtaining concurrence from Caltrans, it is essential to hold the public meeting early in the process to engage the stakeholders. It will be the Project's objective of informing and obtaining support from the public and stakeholders. One public meeting will be held during the PS &E
