The State of California Department of Transportation (Caltrans) is currently constructing
additional freeway lanes along Interstate 805 within National City, which will require the
relocation of an eight inch (8") sewer main which crosses under the freeway between
Grove Street and Newell Street.
This sewer main was originally installed in about 1958 and services approximately
twenty homes. The main runs from Grove Street down an embankment on the easterly
side of the freeway at approximately 66% slope, bends forty-five degrees at the edge of
the existing pavement where the slope becomes 3%, and then runs westerly under the
freeway to Newell Street.
Caltrans plans call for construction of a gravity wall along the edge of the freeway at the
foot of the embankment. The depth of the wall footing will require relocation of the
sewer main to provide appropriate clearance from the footing.
Caltrans is requesting that the City enter into a Utility Agreement in order to allow
Caltrans to perform the work necessary to relocate the sewer main, consistent with the
attached sewer relocation plans. Caltrans will reimburse the City, on a time and
materials basis, for plan reviews and inspections. The existing facilities are lawfully
maintained in their present location and qualify for relocation at the State's expense
under the provisions of Section 703 of the Streets and Highways Code.
The construction period for the widening project through National City is estimated for
July 2014 through June 2015. The sewer relocation will occur within this time period
and residents will be notified well in advance via door hangers. Once the sewer has
been relocated, service will be impacted for a period of up to 8 hours in order to
complete the transfer.
