b) Landslide at 1003 Carol Lane in Lafayette May Threaten
Sewer Main
The District received notification from the property owner of Our saviors Lutheran
Church located at 1003 Carol Lane of a landslide which could potentially affect a
District sewer main. staff performed a site visit on February 7, 2011 and
subsequently hired a geotechnical engineer, GeoEngineers, Inc, to visit the site
and investigate the landslide.
On February 10, 2011, GeoEngineers Inc. report cautioned that the slope is
extremely unstable and could further erode. They recommended the
abandonment of the portion of the surer main in the landslide area and
relocation of it as soon .as possible. There are approximately 50 homes
connected to this surer main. staff is evaluating relocation possibilities, but
such relocation is not trivial and would need to be designed and incorporated into
a capital project and constructed next summer.
In the .interim, due to the possibility of continuing degradation of the slope banks,
Collection System Operations (CSO) has made a temporary bypass system
available and the property owner has been informed that CSO may need
immediate access to the site to install the bypass.
c Results of San Francisco Ba Water R.
Control ; Stormw
Pro in Ma and June of 2010
In May and June. 2010, the RWQCB conducted inspections of the Storrnwater
Programs for the Town of Danville and city of Martinez that included reviewing
the Commercial/industrial Inspection programs of the stormwater permit. since
the District provides stormwater inspection services for both Danville and
Martinez under the county clean water Program, Source control staff was
interviewed, and the files and database were reviewed as part of these
inspections. The RWQCB's findings were sent to Danville and Martinez in a letter
dated January 7,, 2011.
The findings included a Notice of Violation to Danville and Martinez for the
Commercial /Industrial Inspection Program in addition to other elements of the
inspections, and presented required actions and recommended actions to which
Danville and Martinez needed to respond. Staff assisted Danville and Martinez
as they responded to the findings and follow -up actions related to the stormwater
inspection services the District provides.
In general, the findings regarding the District's services related to the tinning of
follow -up inspections and, in some cases, the degree of documentation for the
cases cited. A number of examples cited in the RWQCB report were not factually
accurate and appropriate corrections were made in the response. Adjustments to
the inspection services were initiated to respond to the RWQCB report.
