HAZARD ABATEMENT DISTRICT
FROM: J. MICHAEL WALFORD, PUBLIC WORKS DIRECTOR
DATE: APRIL 7, 1992
SUBJECT: AUTHORIZE$70,000 FOR SOIL STABILIZATION AT 2372 SADDLEBACK DRIVE, LOT 54,
SUBDIVISION 5024, BLACKHAWK GEOLOGIC HAZARD ABATEMENT DISTRICT
SPECIFIC REQUEST(S) OR RECOMMENDATION(S) &BACKGROUND AND JUSTIFICATION
I. Recommended Action:
AUTHORIZE an allocation of $70,000 for construction of soil stabilization at 2372 Saddleback
Drive, Blackhawk.
II. Financial Impact:
None.
III. Reasons for Recommendations and Background:
One of the properties in the Blackhawk development, 2372 Saddleback Drive, has experienced
some subsidence of the house over the past several years, and this has resulted in some
distress cracks within the house itself. The District Geologist and consulting geologists have
reviewed the original grading construction plans and have been monitoring the movement of the
house for more than one year. A solution to stop the soil movement, as well as the movement
of the house, includes the construction of a "pinwale' along the back slope of the property. This
pinwall could be approximately 180 lineal feet long, with approximately 30 drilled piers at a depth
of approximately 30 feet each. The estimated budget for this project could total $70,000. Since
the GHAD regulations require that any construction project over $20,000 must be submitted to
the Board of Directors for prior approval, this request for authorization of the $70,000 is being
submitted.
