Rief Property, Seasonal Creek Improvement
NOE - Notice of Exemption
The project will include the installation of a culvert under a section of roadway that has been operating as a wet-ford area. Three 18-inch diameter culverts, approximately 18 feet in length, will be placed using a backhoe or excavator and a soil compactor, the inlet and outlet of the culvert will be armored with rock. An unnamed tributary to Matanzas Creek enters the western boundary of the Rief property via an under road drainage culvert from an upland property. Shortly after the point of entry the creek abruptly turns; it is in this area that the creek bank is eroding and delievering sediment to the stream.
