NOE - Notice of Exemption
Document Description
The project is limited to the construction of a 12-foot-wide and 40-foot-long free-span vehicular bridge. Bridge construction will include installation of associated drilled piers and wing walls outside of the top of bank of Matanzas Creek. The abutments, wing walls, and bridge deck will cause a permanent impact to the riparian habitat of approximately 680 square feet and 25 linear feet. Grading and installation of the bridge will cause a temporary impact to the riparian habitat of approximately 2,700 square feet. Access will occur via existing vineyard roads. As part of the project, six oak (Quercus. sp.) trees will be removed from the riparian habitat. The project will also include the installation of two four-inch high-density polyethylene (HDPE) pipes for utilities across the creek, approximately 100 feet northwest (downstream) of the new bridge location. The pipes will be installed at least 10 feet below the creek bed using a jack and bore method, and drilling fluids will not be used therefore there is no potential for a frac-out. Bore pits on either side of the creek will be outside of the riparian habitat and will not cause any impacts.
