RTI Manchester, Inc. Manchester Subsea Cables Project
Document Type
MND - Mitigated Negative Declaration

Document Description
https://www.slc.ca.gov/ceqa/. The Project would install subsea fiber optic cables for telecommunication services connecting California to four different locations in Asia and Australia. The Project includes installation of structures on land (terrestrial) and in ocean (marine) just north of unincorporated town of Manchester, Mendocino County. The Project involves installing four 5- to 6-inch-diameter steel conduits offshore, primarily through horizontal directional drilling extending approximately 0.6 miles offshore from an onshore landing site and installing approximately 1 O miles of underground conduits onshore on both sides of the State Route 1 and other public roads to one of three cable landing stations in Manchester. The cables would be pulled from offshore through these conduits and, once connected, would transmit signals to the technical hubs in Silicon Valley.
