Who is responsible for which part

Thousand Oaks draws its line at the main and says so in one sentence. Section 10-1.407 of the municipal code provides that "the installation, maintenance, repair or replacement of service laterals and other facilities beyond the City's public main shall be solely the complete responsibility of the property owner or property owners association", and that "the City's responsibility shall cease at the public main". The code splits the run in two for naming purposes - a "building lateral" is "the pipe on private property connecting a building with the service lateral on public property at the property line", and a "service lateral" is "the pipe designed or intended to convey wastewater from the building lateral to the public wastewater pipeline" - and then puts both of them on the owner.

The property owner
Both halves of the run, which is the point of the two definitions. Section 10-1.407 reaches "service laterals and other facilities beyond the City's public main" and makes them "solely the complete responsibility of the property owner", and section 10-1.907 repeats it where a reader is most likely to look: "in the event there is a blockage in the lateral, no adjustment in billing will be made. It shall be the property owner's responsibility to maintain his own system." The City's own Sewer System Management Plan says the same about its own practice - it "does not own, operate nor maintain any portion of the service laterals connecting to the City's sewer system mainlines".
What else is worth knowing
Nothing splits the pipe between the City and the owner. What the code does split is the naming, and it is worth knowing which word applies where, because the two are governed by different sections: the length on private ground is the "building lateral" and the length from the property line to the main is the "service lateral". Section 10-1.407 covers both by drawing the City's line at the main rather than at the property line. There is also an indemnity attached that a reader should see before it arrives in a dispute: the same section has the customer, "by their application for wastewater service", agree to defend and hold the City harmless "for any and all claims of damage or liability to persons or property arising occurring beyond that point".

What is required

  • When you askPermit

    Two permits and an inspection sequence. Thousand Oaks Municipal Code section 8-4.09 provides that "no building, structure or building service equipment regulated by this code shall be erected, constructed, enlarged, altered, repaired, moved, installed, improved, removed, converted or demolished unless a separate, appropriate application has been made and permit for each ... has first been obtained from the building official". Section 7-2.301 adds the street side: "it shall be unlawful for any person to encroach, or to make or cause to be made any encroachment, or to do any encroachment work upon, over, under, or within any right-of-way in the City without first obtaining a permit from the City Engineer", and encroachment is defined to include "excavating" and "constructing, placing, or maintaining any ... pipe, conduit, or cable on, over, under, or within a right-of-way".

    What to do: Book both permits before work is scheduled - the building official's and the City Engineer's - and confirm with the contractor that the trench will stay open for two separate inspections rather than one. Give Public Works the twenty-four business hours' notice in writing. If the work will change the lateral's size, depth or position rather than replace it as it was, raise that with Public Works early, because section 10-1.410 makes it a separate approval with its own fees. In a genuine emergency section 7-2.609 allows the work to start, with a written permit applied for on the first working day afterwards.

    Why this matters

    The sequence is what catches people, because two departments inspect different parts of the same trench and the pipe cannot be buried until both have been. Section 10-1.408 provides that "the Public Works Department shall inspect and approve the connection of the lateral to the wastewater main line and the Community Development Department shall inspect and approve the service lateral connection to the building lateral prior to the backfill of such lateral installation", and requires the Public Works Department to be "notified at least twenty-four (24) business hours in advance of any connection to the wastewater system". Business hours, not hours - a Friday afternoon call does not buy a Saturday inspection. Changing the pipe rather than replacing it like for like is governed separately: section 10-1.410 requires approval and fees for "all changes to the Public Works Department's wastewater system including changing the size of the service lateral, relocating of any facilities, raising or lowering any facilities".
