Acton Emergency Preparedness Fair
2026-06-16 17:00 - 19:00 | NARA Park Bathhouse Pavilion, 75 Quarry Rd, Acton, US
Be More Resilient in the Face of Emergencies!
Acton’s Emergency Preparedness Fair is an opportunity to learn a few basics about preparedness, including the types of emergencies we might expect in our area. Explore how residents can be ready for power outages and how to be more resilient in the face of weather extremes, such as windstorms, rain “training” and flash floods, heat waves, and even fire or hurricanes. Find out how to build a ‘go kit’, what supplies you might need to have on hand for different situations, and what extra preparations are needed for kids, pets, and older adults. Please come and share your questions with Town employees and local preparedness organizations.

The event features demonstrations, giveaway items, and preparation resources, along with free food and fun activities for the kids. Find us under the eaves at the NARA Park Bathhouse Pavilion, next to the beach.

In the aftermath of an emergency, access to critical supplies may be limited. Find out how we can be better prepared, not just as individuals and families, but as a community. Indeed, as other United States and international emergencies have shown, our changing climate means that we must learn to rely on each other in new ways. The Acton Emergency Preparedness Fair is way to strengthen communication and cooperation as we move forward.
This event is sponsored by various Acton Town departments–the Sustainability Office, the Fire Department, and the Health & Human Services Department. Come by rain or shine.

The NARA Park Bathhouse is located at the first parking lot next to the pond.
Please join us! Drop in any time!

From Canopy to Ground Layer - Building Soft Landings with Keystone Plants for Pollinators
2026-06-16 19:00 - 20:00
Building Soft Landings with Keystone Plants for Pollinators
This presentation explores the powerful connection between keystone plants and the insects that depend on them. You’ll learn how to implement “Soft Landings” in landscapes of all scales from home gardens to larger managed sites. This innovative habitat design and management strategy focuses on creating lush, drought-tolerant mini ecosystems beneath native trees to support pollinators throughout their life cycles. Participants will learn what defines a pollen specialist, discover examples of these fascinating bee-plant relationships, and understand how keystone plants function as foundational species in our ecosystems.
You’ll benefit from practical strategies on site preparation methods, herbicide considerations, and building a resilient plant matrix of sedges, cool-season grasses, and flowering keystone species. By the end of the presentation, participants will be equipped to design and install a Soft Landings planting that transforms conventional landscapes into thriving sanctuaries for bees, caterpillars, and other beneficial insects.
Our Speaker: Heather Holm is a pollinator conservationist and award-winning author of four books: Pollinators of Native Plants (2014), Bees (2017), Wasps (2021), and Common Native Bees of the Eastern United States (2022). Both Bees and Wasps have won multiple book awards including the American Horticultural Society Book Award (2018 and 2022 respectively). Heather’s expertise includes the interactions between native pollinators and native plants, and the natural history and biology of native bees and predatory wasps. Her work has been featured in the New York Times, Minneapolis Star Tribune, and many local publications. Heather is also an accomplished photographer and her pollinator photos are frequently featured in print and electronic publications.

From Gas Pumps to Charging Stations: EV Basics for Everyday Drivers
2026-06-17 19:00 - 20:00 | Zoom
Now Is the Time to Go Electric!
With local gas prices climbing toward $4.50 a gallon, the financial case for making the switch to an electric vehicle has never been stronger. Charging an EV at home on Eversource East costs the equivalent of just $2.80 per gallon – saving drivers roughly 38% per mile. And the savings don’t stop at the pump. Because EVs eliminate oil changes, spark plugs, and complex exhaust systems, they cost 30–50% less to maintain over their lifespan than gas-powered cars. All told, drivers can expect around $4,000 in total cost-of-ownership savings over the first five years.
Although the supply of new EV models is a bit unpredictable at the moment, there are still great options out there. And do not forget the used EV market, where most vehicles are also eligible for the Massachusetts MOR-EV incentives ($3500). The volunteer inputting this information just turned in a 2023 Kia EV6 with only 17,000 miles. A wonderful vehicle at a HUGE savings. We bought a 2026 Hyundai Ioniq 5 to replace the leased car and got a very good deal on the new vehicle. Please do not let our topsy-turvy market circumstances prevent you from finding a vehicle that you will love!
Whether you’re looking to purchase or lease, now is a great time to lock in immediate, predictable savings. Hear directly from EV drivers, get your questions answered, and take the next step to going electric. Register for the MassEnergize online webinar on June 17, 2026, 7–8pm: www.bit.ly/EV-101.
And stay tuned for the EnergizeActon.org EV Petting Zoo coming up in July. This is a wonderful yearly event for EV drives to meet up, plus potential EV drivers can check out the cars and ask lots of questions!
