9/15 – Reef Ball Build @ CBEC

September 15 @ 8:00 am - 12:00 pm

Join us to build Reef Balls at the Chesapeake Bay Environmental Center.

For this project we’re proud to be working with our great friends at the CBEC to build important shoreline protection for the region.  These reef balls will provide important protection against erosion and support the growth of SAV in the shallows in the region.   We’ll bet that they’ll also create a great place to catch a perch or a rockfish in a few years.

There are multiple nature trails for an enjoyable hike or bird watching on the grounds, and you may also rent kayaks and enjoy some peace and quiet once volunteering is complete. For their story, visit bayrestoration.org and find out more about CBEC.

Reef Ball Build FAQs

What is a Reef Ball?

Reef balls are a specially designed artificial reef unit that are used worldwide to build and restore reef habitat. Here in the Chesapeake, reef balls provide important three-dimensional habitat for oysters and many other filtering organisms to attach to. They also provide hollow structure for juvenile fish and crabs to hide from predators. Yes, it’s those predators we pursue as anglers, so reef balls also make some great fishing spots too.

What am I volunteering to do?

Volunteers will be working on behalf of CCA Maryland. You will be outside in teams (or individually) to assemble reef ball molds and then help fill the reef balls with concrete delivered from a truck.

Bathrooms are available, as well as a place to sit in the shade and enjoy your lunch or take a break.

This is a simplified version of what we do for the Living Reef Action Campaign when working with students or other partners.  For most reef ball builds, we hand mix concrete or use small electric mixers.  For others, a concrete truck will arrive and you will help fill the molds you’ve assembled using gravity as your friend.

Depending which day you attend, you may remove the molds from previously built reef balls first and set molds up for another pour later that day.

Can I bring a group of friends or colleagues?

Yes!  There is no maximum sized group to participate.  We will aim to build around 25 reef balls per day, and can likely add to that number with additional molds for the right group.

To discuss organizing a reef ball building activity for your group or company, please contact David Sikorski at (443)621-9186 or via email to david@ccamd.org.

What should I wear?

We’d recommend long pants and multiple layers in light colors. For one, lighter colors are cooler in the sun. What’s the second reason? Some say that biting flies seem to be more attracted to darker fabrics.

Bring layers and changes of clothes based on your own assessment of the weather. We have gloves you can borrow. Closed toed shoes are best, especially ones that you can get dirty.

I'm ready to RSVP, what's next?

Click the red "Volunteer for this Reef Ball Build" button, or visit our volunteer page.

When filling out the form, first select “Reef Ball Build” as your area of interest.

Next, click the Select and Event button and select this date.  You may submit multiple applications for volunteering.

The RSVP is largely used so we can communicate with you leading up to the event and let you know if there are any changes due to weather, or other common logistical headaches.

When you volunteer, your name is added to a list for each day, and whoever is in charge of that days work will communicate with you.

If you have trouble getting in touch with someone or with our system.  Please contact David Sikorski @ 443-621-9186.  A text message may be the quickest way to connect with him and schedule a time to talk.
