A Canadian developer planning to build a warm-water attraction next to Arrowhead Golf Course in Douglas County has received a cold reception from neighbors, including the course operator. “A commercial development in this neighborhood would be a colossal disaster. Not just for the wildlife, but for the people who live here,” said Bridget Epp, 64, who’s lived in the community for eight years. Epp is a leader of the local “Save our Rox” group, which for the last three years has been pushing back against plans to develop a 35-acre site largely surrounded by the golf course.
