HELIX  is preparing technical studies for the 12 Oaks Winery Resort project in the Temecula Wine Country area of unincorporated Riverside County. The resort includes a 35,000-square foot winery, 248-room hotel/conference/event center, and 86 single-family residences, along with vineyards and open space. HELIX is preparing biological resources, cultural resources, air quality, greenhouse gas, and noise technical reports, as well as overseeing preparation of a paleontological resources technical report by a subconsultant and conducting resource agency coordination. As a part of the cultural resources report, five previously recorded archaeological sites were updated to reflect their current condition and newly identified isolates were recorded.
