This is the tribe's 12,300 residential unit project that has been on hold since early 2008:

SPECIFIC PLAN NO. SP00375 (Travertine Point Specific Plan) The
Travertine Point Specific Plan is proposed by Black Emerald, LLC in
consultation with the Torres Martinez Desert Cahuilla Indians. The
Specific Plan area currently consists of approximately 5,131 acres of
land of which 4,148 acres (approximately 81 percent) is within
Riverside County, and 983 acres (approximately 19 percent) is within
Imperial County. Approximately 1,419 acres (approximately 28 percent)
of the total Specific Plan area consists of land located within the
reservation of the Torres Martinez Desert Cahuilla Indians; 785 acres
within Riverside County and 643 acres within Imperial County. The
portions of the Specific Plan controlled by the Torres-Martinez will
be processed under the requirements of the tribe and, as appropriate,
will be subject to additional environmental reviews under the
National Environmental Protection Act (NEPA) per 40 CFR 1501.5
because the Torres Martinez Desert Cahuilla Indians are designated a
sovereign nation. The proposed project consists of a Specific Plan
that would master-plan approximately 5,130 acres as a residential
mixed-use community. This specific plan includes several residential
or mixed-use colonies, each with its own mix of land uses. The
colonies included in the specific plan consist of (1) the Town
Center, (2) the Resort and Marina, and (3) the Residential Colonies
(Golf, East, and West). The Travertine Point Specific Plan envisions
98 acres of commercial use including 100 residential units, 87 acres
of mixed use development including 700 residential units, a 34 acre
Business Park, 127 acres of resort and marina activities, 2,239 acres
of residential uses containing 11,500 units representing various
densities, styles and concepts, 276 acre golf course, 2,061 acres of
open space, and 208 acres of roads. The total specific plan will
contain 12,300 residential units when completed. The plan will also
contain a Cultural Resource Preserve which will celebrate the unique
culture of the Torres-Martinez Desert Cahuilla Indians and their use
of ancient Lake Cahuilla, as well as a Living Desert that will
exhibit the unique flora and fauna that make up the lower Colorado
desert and the Salton Sea.
