By GRAD File&Clerical Binder � £Deputy R.Short,Kleinfelder,Inc. t 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.
