Temenos Estates, Anguilla, Bwi Hydrogeologic Investigation, Geophysical Mapping and Water Supply Development

N. S. Nettles & Associates, Inc. (NSN) was contracted by Flagg Luxury Properties to perform a<br>hydrogeologic investigation of its Temenos property, the former Sonesta Resort, on the island of<br>Anguilla, Rendezvous Bay, BWI (Figure 1). Temenos Estates is a $300 million dollar development<br>comprised of a St. Regis Resort Hotel, Greg Norman Golf Course, private beach estate homes, and<br>private villas (Figure 2). The project site incorporates nearly one mile of beachfront property with<br>fringing reefs. Land elevations rise from the beach to elevations of 80 feet above sea level (Figure 3).<br>The island is of volcanic origin but has in excess of 300 feet of limestone overlying the igneous rocks.<br>Two large hydric geomorphic features are present on the property that will be modified as part of NSN’s<br>scope of work. One feature is a 12 acre salt barren (a sea level plain with hyper-salinities) referred to as<br>the savanna, that was formed by a large sinkhole many thousands of years ago. The second is the 13-<br>acre Merrywing Salt Pond that was originally used to mine salt and was later used as the disposal site for<br>the Sonesta Resort septic system. This salt pond is also hyper-saline and very high in nutrients. The<br>investigation was designed as a three-phase program to define the hydrogeology of the site, construct<br>water supply wells, drainage wells and flushing channels.
