I updated your cc lines to our new City Manager and Assistant City Manager. I have also included our Mayor and City Council via the bcc line (this is our common practice to ensure that we do not violate any open meeting rules that the Council must follow when discussing topics in groups) While we have been monitoring the volumes on West Las Positas for the past several years and have been very focused on the volumes in this last year preparing for the Multimodal Reconstruction Project, we had hoped that the change in the merge location would not increase delay or cause intersections to become blocked. The previous AM backup was to around Payne Road and the striping project that we completed 2 weeks ago to improve the pedestrian crossing distance at Payne Road included the shifting of the merge 700 feet to the east. This shift should have moved the backup about 1000 feet to the east (closer to Dorman Road). But when we laid out the initial merge location. I didn't like the way it flowed through the curve. so I moved it further to the east This was as it turns out, slightly too far when we have 100% student attendance at Foothill. The first week of the new striping had congestion between Dorman and Hopyard, which was expected, but last Wednesday — Friday was really bad I believe that the reason for this is that Wednesday was the start of finals, which means that the normal 10% reduction in traffic we get due to the A period students arriving 1 hour before the rest did not occur: that coupled with the very high attendance rate (low absentee numbers during finals) added enough vehicles to extend back to and through Hopyard Road. While this backup only lasts 5 cycles (10-15 minutes). we don't want install bicycle and pedestrian improvements that will significantly impact vehicle operation. So, while the AM congestion was only 15 minutes out of the day, we will be modifying the striping over the summer to ensure that the backup will not impact Hopyard Road when school returns in the fall. For your second location of westbound West Las Positas at Coronado Lane, we are designing improvements to "square up" the intersection so that the turn resembles a standard 90-degree intersection. The previous design created a condition that allowed cars to turn at a faster than normal speed. Our design will shrink the crossing for the pedestrians and slow down the vehicle turning speed. I do understand your request to have a design that accommodates a comfortable turn for vehicles and we will incorporate that into the design (although we are not going to have a right turn lane for Coronado— we want to limit the number or right turn only lanes. The reason for limiting these. is that right turn lanes are challenging designs for bicyclists. To meet our"all ages and abilities" standard, we want to make riding in the bike lane as comfortable as possible. Adding a right turn lane requires bicyclists and vehicles to weave across paths increasing the number of conflict points. The level of comfort is also significantly reduced because a right turn pocket requires that bicyclists ride between the through travel lane and the right turn lane, essentially placing the bike between two vehicles —we want to avoid this wherever possible) We will incorporate a design that maintains a level of comfort for both the bicyclists and the vehicles while improving the crossing distance for pedestrians. Thank you again for your email to the City to express your thoughts and solutions. 4
