HELIX Environmental Planning (HELIX) conducted environmental consulting and cultural resource management services for the Lake Wohlford Dam expansion project for the City of Escondido. The City proposes to raise the current water level by reconditioning the dam and other related components to allow a larger capacity of water to be contained. HELIX conducted cultural resources surveys of the area of potential effect surrounding the lake, recording eight previously undocumented sites and five isolates, as well as updating 14 previously recorded sites. HELIX also prepared archaeological reports and maps, and conducted Native American outreach.
