Erik grew up on the Severn River at a time when its sub-aquatic vegetation was virtually non-existent, and the River was approaching full build-out. Having also spent time living near Spa Creek and the South River, he has seen firsthand the results of neglect and abuse on Anne Arundel County's waterways. He lives on Deep Cove Creek in Churchton with his wife, daughter, and son.
