Travis,
Attached, please find staff recommendations for traffic calming strategies to address the high speeds identified
in the Righetti Ranch traffic monitoring study (also attached). I’ve tried to avoid unreasonable
recommendations that would require significant costs, such as permanent corner bulbouts, raised intersection
construction/reconstruction, etc., focusing on features that have proven effectiveness with a high cost/benefit.
Here’s a summary of what we’re recommending:
1. Righetti Ranch Road south of Twin Creeks
a. Install a left yellow edge stripe adjacent to the medians in both northbound and southbound
directions, which visually narrows the traffic lane widths, which can help with reducing vehicle
speeds.
2. Righetti Ranch Road between Tiburon and Hayfield
a. Install 2 speed tables per City Standard Plans (included in attachment)
3. Tiburon between Righetti Ranch Road and Orcutt Road
a. Where on-street bike lanes exists, add a striped bike buffer to visually narrow the auto lane
widths, which can help with reducing vehicle speeds
b. Install one speed table just west of Imel. Use City Standard speed table modified to keep the
edges of the table out of the on-street bike lane, which can create a trip/fall hazard. Westcreek
just constructed 2 such tables on Ranch House Road and I’ve included the details showing this
modified table design in the attached.
Please let me know when you’ve had a chance to review and digest so we can discuss next steps. With
Westcreek’s recent traffic calming on Ranch House Road, they had the same engineer that prepared their
original PIPs add these traffic calming elements and submitted as plan revisions under the original FMAP case.
They installed their speed tables a few weeks after plan approval and we subsequently released their bond for
traffic calming mitigation. I imagine we could do something similar here.

Travis,
I’ve reviewed the memo and have a few minor comments (see attached).
It looks like we do have speeding issues on both Righetti Ranch Road and Tiburon. I’d like to spend a little
more time reviewing potential traffic calming mitigation strategies in coordination with our Transit and Fire staff,
but even if the ultimate recommendation was to install speed tables on each of these segments w/
conservative spacing (300-600 feet between each table), the total cost should be well within the $200K bond. I
would be supportive of clearing the $25K bond, but continuing to hold the $200K bond until these solutions are
in place.
Thanks,

Thanks Luke. Any chance you can review the study today or tomorrow. My bond premium is past due and I would like
your ok to release the small $25k bond as we discussed. This will leave you the duplicate bond for $200K. Let me know
so Hal and Matt can issue the release once you are comfortable. Travis

Thanks Travis. I’ll review and huddle up with you early next week on these findings and next steps.
Thanks,
