Phase II Construction

Construction of Phase II of the Cullinan Ranch Restoration Project began in August, 2012 and was completed in January, 2013. Objectives of this phase are to complete the construction of the highway protection levee, improve the levee forming the western boundary of the site, and install public access infrastructure at the Pond 1 Parking Lot. At the parking lot there will be a USFWS Kiosk with a viewing area, interpretive panels and benches as well as a 1.5 mile trail out to another viewing area on South Slough. In addition, a state of the art, universally accessible fishing pier and kayak launching facility will be constructed a short distance from the parking lot.
