Every year, Dewees Island hosts an environmental building products show for property owners, architects, builders and the general public. Development is limited to 150 homesites on the 1,206 acre island. Each homesite is restricted to a 7,500 square-foot disturbance boundary. Sixty-five percent of the Island has been designated as a wildlife refuge and is protected against any future development whatsoever. Private boat docks are prohibited.
Owners share developer-built community docks.
Owners are required to use indigenous or native plants for landscaping and gardens, thus eliminating the need for irrigation, pesticides and fertilizers. Transportation on the island is restricted to electric vehicles. All roads and driveways are constructed of natural sand. As a result, stormwater management is simplified, erosion and runoff are reduced and increased recharge rates for the aquifer are achieved. No golf courses will ever be built.
