Phase III Construction

Construction of Phase III of the Cullinan Ranch Restoration Project is scheduled to begin in Summer 2014. This phase will include protecting a 3 mile stretch of the Highway 37 emankment from erosion with rock rip rap and ecotone slopes. Additionally, a lane for the safe ingress and egress to the Pond 1 parking lot will be constructed and will involve widening the highway embankment in the vicinity. Phase III is expected to be completed by December, 2014.
