SUBJECT: ACCEPT and APPROVE the Fiscal Year 2006/2007 Program Budget for the Hillcrest Heights Geologic Hazard Abatement District, as recommended by the Hillcrest Heights Geologic Hazard Abatement District General Manager, William B. Wiggington, GEOLEX, Inc., El Sobrante area. (Hillcrest Heights GHAD Funds) (District I) Project No. 7756-6X5396 DATE: December 12, 2006 PAGE: 2 REASONS FOR RECOMMENDATIONS AND BACKGROUND: On July 23, 1996 the Contra Costa County Board of Supervisors adopted Resolution 96/329 approving the formation of the Hillcrest Heights Geologic Hazard Abatement District (Hillcrest Heights GHAD). The Board at that time appointed itself as the Board of Directors for the Hillcrest Heights GHAD. Resolution 97/178 adopted on April 1, 1997 by the Board of Supervisors, acting as the Hillcrest Heights Board, confirmed the assessments for the District and ordered the collection of the amounts called for in the Assessment Report. The initial fiscal year for-the district was established as 1997-1998. William B. Wiggington of GEOLEX Inc., was contracted by the Contra Costa County Public Works effective July 1, 1997 to assume the role as District Manager/Geologist for the Hillcrest Heights GHAD. Mr. Wiggington continues to serve in that capacity under a contract that has a completion date of July 31, 2008. The Program Budget anticipates the salaries of the General Manager/Geologist as well as those of hired consultants and support services. Legal fees, accounting and insurance, County Staff services, and GHAD association membership are included. The annual repair, maintenance, and improvement program is essential to keep Hillcrest Heights GHAD assets in operation including, general maintenance, erosion control measures, and mitigation measures (sandbagging and hydroseeding). On a periodic basis each year, the Hillcrest Heights GHAD will also monitor and maintain the following items: inceptor ditches, piezometers and hydraugers, survey points and benchmarks, and subdrains. The Hillcrest Heights GHAD Draft Program Budget table is intended to summarize the approved budget. The attached report detailing the various programs and activities of the Hillcrest Heights GHAD is provided for the information of the Board of Directors. The General Manager may reallocate funds within each of the above major categories without prior approval of the Board. GEOLEX Inc. is proposing that the Board accept and approve the attached proposed Program Budget. CONSEQUENCES OF NEGATIVE ACTION: Without the Board of Supervisors' approval, the GHAD will not have an approved budget as required by the original formation of the GHAD. Consequently, repairs will be delayed and potentially result in increased costs due to enlargement of the slide areas. 11/20/2006 16: 18 8316620609 GEOLEX INC PAGE 01 Project Number 0917 November 20,2006 TOi GRAD Board of.Directors(CC Co.
