🌊 Second Beach Cleanup Success!
This past weekend, our fraternity partnered with the City of Long Beach Adopt-A-Beach Program and the California Coastal Commission through the Department of Parks, Recreation & Marine to host our second beach cleanup!
We’re proud to share that Bluff Park Beach is now officially our adopted beach - and we’re committed to keeping it clean and beautiful for everyone to enjoy. 💙
Together, we collected 27 bags of trash, removing 107 pounds of debris and litter from the coast 🌎, and completed 88 hours of community service by Theta Tau Xi Epsilon members and affiliates!
Thank you to everyone who came out to make a difference, one beach at a time.
