Mr. Brozosky said another advantage to having four lanes of traffic would be to eliminate the vehicles from racing in this area. He asked if there would be sufficient rooms for vehicles to park and accommodate bicycle lanes on Vineyard Avenue between Bernal Avenue and Montevino Drive once the medians were installed? Mr. Wilson said staff has not prepared the designs for Vineyard Avenue between Montevino Drive and Bernal Avenue. Staff is intending to include in the design documents parking, bicycle lanes, left turn storage, and medians. Mr. Brozosky compared the costs for replacing the roundabouts with stop signs or traffic signals and noted the traffic signals the City has been installing have not cost between $220,000 and $320,000. Mr. Wilson said staff included in its estimate, $200,000 for a traffic signal assuming that it would be a speed sensitive traffic signal. Additional costs were not included either for the stop sign or traffic signal, which are directly associated to the widening of Vineyard Avenue to accommodate a left turn lane. Mr. Brozosky recalled that the proposed traffic signal did not meet CalTrans requirements for traffic conditions nor did the traffic signal installed at Montevino Drive. Mr. Wilson said the traffic signal installed at Montevino Drive was an attempt to correct the issue of having four-way stops to make it functional. The other option would have been to remove the stop signs; however, after having that type of control the direction was to install a traffic signal. Mr. Brozosky expressed his concern regarding the proposed traffic signal that would serve trail users crossing Vineyard Avenue and also residents exiting Petronave Lane and the home sites just north of the intersection particularly due to the limited sight distance to the west. He asked if there would be potential issues for problems associated with this traffic signal? Mr. Wilson said staff has not designed how far back the flashing yellow beacon would be installed. The intent would be to place the flashing yellow beacon back far enough so a vehicle has sufficient time to react. Staff does not believe this will be an issue, which is why it is recommending the use of flashing yellow beacons. Without the traffic signal, there is an issue of pedestrians being able to cross in a safe manner. There is a potential issue if vehicles are completely backed up; however, the majority of the time the traffic signal will remain green and the flasher will not be going off unless vehicles are leaving the driveway off of Petronave Lane or someone using the trail wishes to cross. Mr. Brozosky believed it would be better to locate the traffic signal at the end of the S- curve, which would allow for better visibility and make it a safer location for pedestrians to cross. Mr. Knowles said staff is following the guidelines of the Vineyard Avenue Corridor Specific Plan, which designated where the trail crossing would be located. Staff is trying to design the trail in such a way that it is a fully off-street trail and in order to change the location of the proposed traffic signal, some type of additional street pathway would need to be extended to connect pedestrians to the trail.
