Sustainable Cities

We’re excited to continue building AI in Practice with our monthly social! 🎉 Each month, we’ll host an informal happy hour and dinner at Upside on Moore in Rosslyn. Come join fellow AI builders, professionals, and curious minds for a relaxed evening of conversation, connection, and community.

We’re so grateful for the early enthusiasm, and we look forward to seeing you each month as this community grows! **Date, Time & Location** 5:30 PM – 7:30 PM Thursday 23 October 2025 Upside on Moore 1831 Moore Street Arlington, VA 22209

Project needs vary but often include brainstorming, researching, writing, coding, or analyzing data. Check out [our website](https://www.civictechdc.org/projects) for a list of projects which may make an appearance! Meet other civic tech enthusiasts. Learn new skills. Contribute to a project to improve a local civic issue. **All are welcome and collaboration is encouraged.** Laptops are recommended but not required. **Where do I register?** To better serve our growing community, we’re transitioning our event registrations to [Luma](https://luma.com/civic-tech-dc)! **We still love Meetup** Meetup has been an incredible platform for us to build and connect with our community. We’ll continue sharing upcoming events there so that new people can find us, but [Luma](https://luma.com/civic-tech-dc) will be our primary registration platform moving forward. **Why we're making the switch** Meetup’s registration system has some limitations, and we need more flexibility to manage sign-ups and engagement. \-\-\-\-\-\- [REGISTER FOR THE EVENT HERE (ON LU.MA)!](https://luma.com/12sf0fvk) \-\-\-\-\-\-

For the Wednesday run, let's meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse) before walking over to the Crystal City Water Park and run on the Mt. Vernon Trail alongside the scenic Potomac River. LOCATION: Meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse). Link to location on map: http://i.imgur.com/3yN0lwN.jpg NOTES: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms. Let's meet at 6:50 PM, leaving by 7:00 PM. We will do 50 minutes, so 25 minutes out and 25 minutes back. You're welcome to do more if you'd like. Just before the run we decide whether we'll go NORTH (DC) or SOUTH (Old Town) on the trail. Once we're done, we meet back up at the Crystal City Water Park area. After the run please feel free to hangout and socialize with the group or join us at Highline RxR in Crystal City (National Landing) for a beverage and/or food. https://g.co/kgs/AErMQZ All paces are welcome! We run by time, not speed so bring a watch to monitor your time and turn around at the halfway time point. If you need to run/walk, that's ok! We average anywhere between 7-13 minute/per mile pace. First Time? Start out slow to find someone around your pace. The different paces tend to automatically gather, so you won't be alone! Metro: Crystal City on Blue/Yellow lines, 2 blocks from metro exit. Parking: There is plenty of free parking inside the garage directly across from the Crystal City Water Park. Post-Run: A lot of times we have a little social outing after the run. You can bring a change of clothes if you'd like (though most people just go as is). We'll finish up the run, meet back at the Water Park, pick up our wallets and walk to wherever we decided to go for a beverage and/or food. If you have a suggestion for a place to check out, let us know!

A few years back, Amazon created a new TV show about the Tom Clancy character Jack Ryan. Somewhat infamously, [Jack Ryan's Morning Commute](https://dcist.com/story/18/09/04/jack-ryans-commute-to-work-makes-ab/) makes no sense. So this walk is inspired by the route he should've taken Part 1 (9.5 miles) - https://maps.app.goo.gl/2pmXJaixbXQxnvfv8 1\. Foggy Bottom metro 2\. Potomac Boat club 3\. Chain Bridge 4\.

He will describe how to install a bog and fill it with many interesting native plants including pollinator and host plants https://columbus.wildones.org/calendar-of-events-and-programs/?wo_event_id=11160

Free at Bexley Library Adventures in Ecological Horticulture with Rebecca McMackin Wednesday, March 18 1:00pm - 2:30pm Gone are the days when a garden could be ornamental alone. We now recognize the impact that our land care practices have on the ecosystems around us, and can see the importance of encouraging biodiversity. Thankfully, we do not need to sacrifice beauty when we invite butterflies and songbirds into our gardens. Rebecca McMackin has cultivated gorgeous landscapes in the toughest environments possible: urban parks, school playgrounds, and the sidewalks of New York City. She will take lessons from her work at Brooklyn Bridge Park, the Brooklyn Museum, and decades of research to share how those of us who are fortunate enough to care for land, can do it beautifully and ecologically. Rebecca McMackin is an ecologically obsessed horticulturist and garden designer. She writes, lectures, and teaches on ecological landscape management and pollination ecology, as well as designs the rare public garden. She is currently Lead Horticulturist for the American Horticultural Society, an Associate with the Harvard Divinity School’s Thinking with Plants and Fungi Initiative, and Consulting Arboretum Curator for Woodlawn Cemetery in the Bronx, NY. Rebecca spent a decade as Director of Horticulture of Brooklyn Bridge Park, where she managed 85 acres of diverse parkland organically. Their research into cultivating urban biodiversity and ethical management strategies has influenced thousands of people and entire urban parks systems to adopt similar approaches. She has been published by and featured in the New York Times, Gardens Illustrated, on NPR and PBS. Her garden for the Brooklyn Museum recently won the PPA’s Award of Excellence and her TED Talk has been viewed over a million times. She holds M.Sc. from Columbia University and University of Victoria in landscape design and biology and recently completed the Loeb Fellowship at the Harvard Graduate School of Design. This program is presented in partnership with Rooted in Bexley and generously funded by the Bexley Community Foundation and Bexley Community Author Series Fund.
