CITY COUNCIL AGENDA ITEM NO. 17
Meeting Date: April 24, 2001
Subject/Title: Notice of declaration that the sewage collection system for Assessors Parcel Number 016-010-016 (Davis Camp) is an eminent threat to public health and intent to remediate with the City and effected property owner sharing expenses
Submitted by: Thom Head, Public Works Department
Approved by: Jon Elam, City Manager
Accept this notice of intent to repair the Davis Camp sewer lateral.
The property identified as APN 016-010-016 (commonly known as Davis Camp) includes 17 residential units and a small neighborhood market. Wastewater from these units is collected in a substandard, privately owned and maintained (Section 13.04.090 of the Municipal Code), house sewer system and is conveyed to the City maintained main sewer collection system via a privately owned bridge across Marsh Creek. Although it has not been physically confirmed, the Cityís Water Treatment Plant is also connected to this system.
On February 2, 2001, a break in the pipe crossing the bridge resulted in a discharge of untreated sewage into Marsh Creek. City crews performed emergency repairs to the system and billed the property owner. Subsequent to the repair, the City was contacted by the State of California Regional Water Quality Control Board, and put on notice that even though the leak into Marsh Creek resulted from the failure of a private system, the City would be liable for penalties (which could be as much as $10,000 per day) associated with any future discharge of untreated sewage into Marsh Creek.
Staff met with a representative of the property owner and discussed repair options. The lowest cost option for repair was to line the existing pipe crossing the creek with new resin based materials. The estimated cost for this type of repair was from $20 - 25,000. Complete replacement of the sewer pipe and upstream manhole with new materials was estimated at $40,000. Subsequent inspections indicated the condition of the existing crossing precluded the lining of the existing pipe, leaving complete replacement as the only option.
Staff has contacted the property owner and offered to immediately proceed with the repairs and to assume responsibility for 50 per cent of the repair cost based on the probability of the Cityís connection to the system.
Staff will proceed with an immediate repair of this system based on the direct threat to the publicís health from a direct discharge of sewage into Marsh Creek, with subsequent invoicing of the property owner for one half the repair costs.
