Help plan the future of SR 37!

Caltrans, the Metropolitan Transportation Commission
and transportation agencies for Marin, Napa, Solano and Sonoma counties are seeking your input on the Future of Highway 37. These agencies will be participating in an upcoming online public Townhall meeting hosted by Senators McGuire and Dodd.

At this meeting the agencies will discuss three coordinated planning efforts to develop solutions for improving SR 37. These planning efforts include:

• An Ultimate Resilient Sea Level Rise Design Alternatives Assessment focused on Highway 37 within Marin and Sonoma counties between U.S. 101 and Highway 121
• A Comprehensive Multimodal Corridor Plan to identify goals, corridor needs and challenges, and project priorities for various modes of travel to inform decision-making and future funding.
• A corridor-wide effort known as the Planning and Environmental Linkage to identify and narrow the range of alternatives to be advanced for environmental review and construction
The public is invited to attend this Townhall to learn more and find out how to become involved in the planning for the future of this critical transportation corridor.

Please review the attached flyer to learn how to become involved and make your ideas heard!

For more information, please visit: www.Resilient37.org

Thank you so much for the cleanup work along northbound Highway 85 in San Jose by the Almaden Expressway offramp! With all the homeless encampments there, this could not have been easy.
Hello, I'm wondering why trash is not picked up regularly and the street sweeper is not sweeping along the HWY 101 & 12 in Sonoma County? The islands in on HWY 12 have lots of weeds and all kinds of road debris around them that are never swept up by the sweeper. It would be nice if this is done more often, it looks very terrible out there like someone does not care. Thanks
The tool bridge at Antioch is very dangerous! You have three lanes of traffic for one lane that crosses the bridge. Motorists have little regards for allowing others to go through the toll that go through first. The five mile per hour speed limit is rarely observed. We use this toll at least two days per week with a high risk of an accident. What can you do to make this safer?
The Centers for Disease control has issued guidelines that state that encampments of people without homes should NOT be dispersed during the pandemic to protect public health. Despite this, this notice was posted in Gilroy today, in an area where 20 individuals are living in tents. These tents are their only shelter and their is not a homeless shelter in Gilroy that has room for them. While we understand the safety concerns, these can be mitigated long enough to give people a chance to locate services and look for housing. We are asking CalTrans to follow public health guidelines and work with local service providers to address safety concerns, including COVID-19
I hate to have to complain on Social Media but I cannot get a response from Cal Trans. We have a retaining wall at the back of our house with a Cal Trans stamp on it. The wall is failing and big cracks are appearing, the wall is also leaning towards our house. I'm certain Cal Trans would not like the liability of having it fail and damage our house or injure anyone. We had a technician look at it over a year ago and agree it needed replacing but nothing more heard... Not really good enough, where do I go from here? location is Mill Valley
What is going on with the amount of trash on 880 in San Jose? There is so much trash that it is a hazard to exit The Alameda traveling N. bound. I have submitted another request on your website but you have not responded to the last one yet! Please do something! I almost hit a mattress! California is such an embarrassment.
What are your plans to clean up the rat infested dump site at University and Frontage, the stench is terrible.
???
I implore you to PLEASE cease the major tree trimming efforts during this nesting season for our local wildlife. I am referring to the work on Westborough Blvd in SSF in this case. We had no rain at all in the early months when this is supposed to be done and now that the birds and small mammals are nesting this action leads to hundreds of deaths to these creatures. I volunteer at my local wildlife rescue group so PLEASE - if you do continue at least contact your local animal center if you find nestlings.....it is the responsible thing to do. Thank you
PLEASE FIX THE POTHOLES ON HWY 680, BOTH NORTH AND SOUTHBOUND, BETWEEN DANVILLE AND DUBLIN! SO DANGEROUS!!!
I am homeless and a homeless advocate in Castro Valley. I just received a call from another displaced resident of the Grove Way/580 abated camp. She along with 3 others moved to a established camp which has been occupied by one other person for a few years now. So they have a total of 5 people in this camp which, is in Eastern C.V, is tucked away and not seen by residents. She stated that ACSO have been there 3 days in a row now and the last visit was yesterday at 3:30pm in which they told her that they had to leave by tomorrow or they would be arrested. It was also mentioned that it was a CalTrans action/eviction. My question to you is...if it is an action taken by you then the protocol is the same as any other eviction. A 72HR notice needs to be tagged at the site giving the residents enough time to gather there belongings, etc. The only notice was verbal done by ACSO deputies and they were given no time tomorrow, even if they did, it is well under the 72 Hr. window. Please advise if this is action is being done on behalf of CalTrans and if so, where is the 72Hr Notice? Thank you for your time and assistance
How many accidents need to happen on Lakeville hwy for CalTrans to take ANY action? ANYTHING? Rumble strips were a waste of money since people who drive recklessly on there don’t care about them. How about some delineators so they CANT pass at those high risk areas? In the last 2 years, 2 people have come though our fence. This resulted in 2 human fatalities, the painful death of an accomplished show horse in retirement,hours of our time and money fixing and cleaning up so our horses can go back, endangered the rest of our horses with an open fence onto the hwy while emergency personal were on scene. This is just OUR property not the others who are in higher risk areas. Yesterday’s accident is on you for turning a blind eye to probably the most dangerous road in your district. 🤬🤬 Thank you to Lakeville Volunteer Fire for always handling the accidents quickly. They are awesome!
