Dehaesus FROM: Costa, Director of Community Development DATE: June 20, 1985 ..County SUBJECT: Blakemont Geologic Hazard Abatement District SPECIFIC REQUEST(S) OR RECOMMENDATIONS) & BACKGROUND AND JUSTIFICATION The Issue At the June 11, 1985 meeting of the Board of Supervisors, the Blakemont Property Owners Association (BPOA) requested the County's financial support to develop a Plan of Control for a Geologic Hazard Abatement Di'strict.(GHAP) in the Kensington area. The area has become known as the Blakemorit slide. Background The Blakemont slide is a complex of small landslides and" broken utility lines in Kensington below Arlington Boulevard and west-to C'olusa*Avenue to withiri'the City i0f El Cerrito. It has affected land, structures And underground erground' lines. ' The boundaries of the landslide are not yet known but include between 100 and,150 homesites and some larger parcels, probably'including part of the.Blake Estate of the University of California'. The 'area is estimated at 19 acres. Damage has been reported since the area was first subdivided in the_ e 19301s, and was aggravated during severe 1981-82-83 winters. Ageology and soils consultant to the BPOA has been selected to prepare a'Plan of Control., The cost estimate to the BPOA is $62,100. However, the estimate will be raised to account for inflation and other factors on July 1st, At 'a meeting on March 21, 1985 between the County Public Works Department, Community Development Department, the BPOA and utility districts (EBMUD, -PG&E*, Stege Sanitary) the consultant, and Supervisor Powers,. it was suggested that the County could support what*would be in effect, a non- guaranteed loan',or "front money"'. Support was 'also indicated by the" utility districts; however, owever, leadership support from. the County, as. the lead jurisdiction; was requested by the others-as a pre-condition. Some assurance was requested indicating that most pro' y pert owners of this area are in support,of the studies, knowing that as a result of the formation of a CHAD, assessments would be added to. their property tax bills. BPOA obtained support of 103 owners, a large majority of-the affected owners. About half would commit $360 to $600 for 15 years, and over one-third would commit $600 to $900 per year.

SUPERVISORS AND COUNTY ADMINISTRATOR M302/7-63 5c BY DEPUTY Board of Supervisors Page Two Blakemont GHAD Once the Plan of Control has been prepared with a stabilization cost estimate, a GHAD could be formed in 30 to 60 days. The cost would be borne by all owners of property including the County and the City of El Cerrito, based on a formula to be presented with the Plan of Control. Bond sales would raise the needed revenue. If a GHAD is formed, front monies would be credited against actual assessments. If a GHAD were not formed, the County's contribution would not be reimbursed. Milton Kubicek of the County Flood Control District has evaulated the benefits of supporting the preparation of the Plan of Control. Briefly, they include the following: 1) Information from the geology, soil and drainage studies for the Plan of Control will help the community and the County staff to better understand the causes of instability and to more carefully watch identified critical areas. It would thereby enable reduced response time to many citizen complaints on problems in the area. 2) The geotechnical report would be obtained by the County for its use as well as use for the homeowners association. Positive action supporting the studies would indicate the County's desire to obtain information necessary to guide its actions to control local movement and drainage problems. 3) With County participation, community interest in controlling the slides should increase. In two ways this attitude enhancement would benefit the community. Favorable reaction to formation of a GHAD and self-assessment should increase, and the individual homeowners would receive information on controlling runoff and local movement on their individual properties. Proper individual actions would benefit the whole community. Financial Impact County participation amounting to $30,000 to $35,000 has been tentatively agreed to be appropriate. The estimated total costs will probably reach nearly $80,000 by fiscal year 1985-86. Recommendation It is recommended that the Board consider, for the 1985-86 fiscal year, a budget item of a maximum of $35,000 for County support for preparation of a Plan of Control for the Blakemont landslide. This matter is scheduled before the Board of Supervisors on June 25th.
