A public-private partnership seems the likeliest way to assure the rebirth of the hurricane-ravaged Flamingo Lodge, for decades a landmark access point to the vast Everglades National Park. The hotel and surrounding cabins were ruined by storms in 2005, and the National Park Service is now looking for ways to finance a new, $20 million project on the site. Plans call for a 30-room hotel and 24 cottages — all built to stricter modern construction codes and elevated on stilts. Another 40 ”eco-tent” structures could be used during cooler winter months and quickly moved for hurricanes. Plans call for solar power to supply most of the project’s electricity.
