Place. The landslide will be repaired by clearing and grubbing; removal of landslide debris; installing a
debris catchment system and installing slope protection materials. The slide left an over-steepened
unstable slope above the subject property. If left unrepaired the slide area is likely to slide again during
the winter and possibly block the driveway at 46 Magnolia.

Without Board approval, the District will not be able to proceed with the repair of the landslide.
Homeowners' property will be threatened with another landslide.

SUBJECT: APPROVE and AUTHORIZE Richard D. Short, Kleinfelder, Inc, General Manager of the
Blackhawk Geologic Hazard Abatement District, to execute a contract with Thomas H. &Peggy
A. Porter, the homeowners of the property located at 917 Eagle Ridge Drive for the repair of a
landslide on said property, Danville area. (District III)Project No. 7760-6X5147
DATE: November 4, 2003
PAGE. 2
III. Reasons for Recommendation and Background.
During the winter of 1998, a shallow landslide occurred on the common slope Behind 923 and 929 Eagle
Ridge, Danville, California. Subsequently, Engeo, Inc. San Ramon, California was retained to observe
the slope failure and make preliminary recommendations. Engeo observed that the slope failure was
actually larger than anticipated involving the upper area of the slope behind 923 and 929 Eagle Ridge.
The unstable area measured 250 wide by 40 feet high. A repair scheme was recommended that included
excavating and rebuilding the slope with a geogrid reinforced fill and a subdrainage system. At the risk
of further slope movement the repair was deferred. Engeo was requested to update their repair
recommendations in February 1999. Again, the CHAD deferred repair. In August 2000, the CHAD
addressed the worsening slope conditions with a request that Engeo prepare detailed slope repair and
keyway construction plans and specifications. The repair was again deferred. By the winter of 2002-
2003 the slope movement had extended further onto the homeowners rear yard area creating a sense of
alarm with the homeowners.
The slope repair project was included in the FY 2003/2004 budget with an estimated cost of repair of
$250,000.00. The delay of the slope repair has caused a deterioration of the slope and created a
condition highly likely to cause severe damage to valuable property consisting of the rear yard area
improvements at 923 and 929 Eagle Ridge unless mitigation measures are taken immediately before the
upcoming rainy season.
Signed License Agreements providing the CHAD with sufficient rights to enter upon and repair the
landslide have been received from the Blackhawk HOA as well as the three affected homeowners. The
License Agreements with the three homeowners provide for the CHAD to partially reimburse the
homeowners the cost of repairing and/or replacing landscaping and other improvements damaged by the
landslide in accordance with the GHAD's interim policy on Funding for the Repair and/or Replacement
of Landscaping and other Improvements Damaged by Landslides.
IV. Consequences of Nezative Action:
Without Board approval, the District will not be able to proceed with the repair of landslide.
