Our Mission

​To educate the public on four key elements of city planning and to advocate for the best solutions to each.

  • Petaluma's current housing stock, and the housing stock in much of the country, has four major problems:

    • We don't have enough of it;

    • Building more housing is expensive which undermines the ability of families to build wealth and pushes the underemployed toward becoming unhoused;

    • Much of our housing is configured such that infrastructure maintenance is financially unsustainable for cities;

    • Much of our housing stock is gasoline, car-dependent which is harmful to the climate and limits those who aren't able to drive because of age, illness, or income.

  • Cars may not go away for a long time. But we must stop building cities to accommodate gasoline-powered cars and instead build them for people. This will require support of electric vehicles and a multi-faceted plan to make transit, bicycling, and walking more available, safe, and enjoyable.

  • Great ideas for more livable cities may come from many places, including Urban Chat, but a financially resilient city hall is required for the ideas to reach fruition. Unfortunately, the coffers of city halls everywhere have been under financial attack for the last century by a combination of land development patterns that aren't financially sustainable and taxpayer revolts.

    To create the financial resiliency cities need, Urban Chat will consistently advocate for better planning and development that improves municipal finances.​

  • Responding to climate change effectively and with urgency is the defining challenge of our time. Two of the largest factors in climate change are our buildings and our transportation system. Urban Chat consistently advocates for urban configurations and transportation alternatives that tackle these two opportunities.​

These four pillars tend to interact in a virtuous cycle: bettering one pays off in the others. For example, housing accessible to transit and bikeways will reduce car travel, CO2 emissions, and city expenditures for roads, road repairs, and parking. Budget savings can flow back into more housing.

Urban Chat advocates for solutions within the four pillars of our mission to feed a virtuous cycle.

How We Started

In November 2011, one of the Urban Chat co-founders began a blog about the need for more walkable urbanism. A few months later, another co-founder, intrigued by the blog, suggested a meeting. On Wednesday, June 13, 2012, a few people met at the Aqus Café and Urban Chat was born. The founders who remain active to this day, are shown below.

Since that founding, Urban Chat has grown from monthly meetings to spinning off committees to testifying at Council meetings to hosting forums and doing whatever else we can to push our mission forward. And we plan to keep doing this for a long time, in part because it's needed and in part because we like the people with whom we share a passion.

In 2021 Petaluma Urban Chat gained nonprofit status through a fiscal sponsorship agreement with Petaluma People Services Center.

Our Founders

Dave Alden was the blogger whose scribblings led to the first Urban Chat meeting. Since that time, he has served as the de facto executive director, spearheading several Urban Chat initiatives while also working to bring in enough other people that Urban Chat will live on when he steps away into an urban retirement of downtown living, sidewalk dining, walking, and transit.


Dan Lyke serves as co-chair for the Know Before You Grow educational committee and is a frequent host of KBYG forums.


​Barry Bussewitz “I once wondered why Petaluma and American cities had to be so inhospitable and often treacherous for daily living. By reading Dave’s blog and joining the Urban Chat, I began to learn the real-life steps we can take to make our urban life accessible, sustainable, warm and welcoming for pedestrians, bike riders, children and other beings, including having homes and transit for all of us.”

Our Contributors

Kevin McDonnell was bothered by the lack of community engagement on developments being built in Petaluma. It seemed the only public meetings had to do with windows and paint color. Then Kevin found Dave and Urban Chat having discussions about all the other issues so important to the way a town develops. Together they believed that there was a public appetite for forums to help understand how the city was going to grow. Kevin helped lead the spin-off of Know Before You Grow as program driven event intended to help educate. Surprise, it turned out education led to being a selective advocacy forum. That led to Kevin's successful run for City Council.


​Sharon Kirk joined Urban Chat in 2017 following a spontaneous meeting with Kevin at the Petaluma Engagement Fair (sponsored by PCRC). Her interest in Petaluma city planning stems from her years of living in vibrant, walkable cities including San Francisco and Gö​teborg, Sweden. Sharon assists with Urban Chat promotional activities and acts as co-chair of the Know Before You Grow educational committee. And despite her hesitation as an introvert, she occasionally hosts events.
