It is the Owner’s responsibility to be sure that they have the most current edition of the Guidelines and have carefully reviewed all applicable sections of the Charter. The purpose of these Guidelines is to ensure that designs are compatible with the site, the overall environment and the design objectives of Palmetto Bluff. These Guidelines are binding on any persons, company or firm that intends to construct, reconstruct or modify any permanent or temporary improvements in the community or in any way alter the natural setting of the Lowcountry environment.

Palmetto Bluff is a sea island with expansive frontage on the May, Cooper and New Rivers. Its intrinsic value lies in the beauty, vastness and richness of its sea island landscape. For most of the last century, Palmetto Bluff has been managed and enjoyed as a private wildlife and forest preserve. Palmetto Bluff has been carefully masterplanned to grow into a complete, balanced, controlled Community within a coastal setting. Its size makes possible the creation of a series of inter-related, yet distinctive settlements and natural preserves. The combination of its location and varied natural features places this unique Community into a class of its own. At the turn of the 20th century, large, majestic landscapes throughout the country were acquired by families to save and enjoy. Many of these authentic and protected places are highly sought-after today because they are timeless and irreplaceable. Palmetto Bluff is one such place. 7 VISION 7 1.1 Palmetto Bluff Major Components t • The Maritime Forest: The landscape zone on the perimeter of the island along the river’s edge is a distinctive mix of ancient live oaks, hardwoods, palmetto and pine, which thrive in higher, sandy, well drained soils. This zone was the prime area during both the pre-historic and historic plantation years at Palmetto Bluff. • The Managed Forest: The interior of the island consists of lands that had been cleared for cotton farming and later managed as pine plantations. Comprised of some 6,700 acres, the Managed Forest is now protected by a development agreement with the Town of Bluffton. This area forms a large “wedge” of open space to be managed for its habitat value. This forest also incorporates undeveloped land to create a link from the New River on the west end of the island to May River Forest at the east end. • Wilson Village: At the heart of Palmetto Bluff, along the deep water of the May River and near the historic sites of the Octagon Plantation and the Wilson Mansion a traditional coastal village, a “gathering place” for all island residents, has been established. The Wilson Village is designed based on principles found in historic coastal towns, such as Beaufort, Charleston and Savannah. It includes a luxury Inn, boutique retail, a boat yard, and a range of traditional residences patterned around a new meandering inland waterway. Small, pedestrian scale blocks lead to a park and esplanade at the edge of May River Forest. • Moreland Village: Located along the deep waters of Cauley Creek, Moreland was originally a part of a 12,000 acre barony purchased in 1730. Planned as the second major Village for Palmetto Bluff, Moreland takes on a more relaxed character and celebrates the outdoors and the casual lowcountry lifestyle. With several amenities planned, Moreland will have many activities for social interaction and connection to the beautiful outdoor surroundings. The architecture and landscape is slightly more informal and relaxed as well, capturing and blurring that connection between the indoors and out. • “Town” & “Country” Neighborhoods: The “Town” Neighborhoods reflect the “civilized” and/or more “urbanized” settlements of the Lowcountry. Included as distinct neighborhoods within the “Town” are The Point, West Wilson, South Wilson, Wilson-Hayfields and River Road.
