Based on my meetings and telephone conversations with 1) Craig Nealis, Rolling Hills City Manager, 2) Lola Unger, Principal Planner for Rolling Hills, 3) Peggy Minor, Manager for the Community Association, 4) Lata Thakar, Los Angeles County District Manager for the Lomita Office (contract engineer for the City of Rolling Ells), 5) Mike Mongomery, Geologist for Los Angeles County, and 6) Dave Poppler, Chief Geologist for Los Angeles County, none of the agencies want to go on record of approving a plan for remedial grading to improve drainage on and over your property. All parties are willing to admit that storm drainage water from the City streets enters your property and exasperates the situation, but no one, at this point is willing to issue a permit to fill fissures or upgrade the drainage due to the perceived liability. The County has suggested that the property owners in the Flying Triangle Landslide area form a landslide abatement district and address the regional problems as a group. At this point, we feel that we have exhausted the available avenues for obtaining a grading permit. We will therefore stop work on this project until we receive further direction from you. Please feel free to call Dave or myself to discuss the City and County response to our plan submittal. Sincerely, ir1 Gary Wynn, P.E. Project Manager cc: David C.

Th following comments are provided in response to a recent verbal request from Ms. Lata Thakar regarding remedial work proposed on the active Flying Triangle Landslide (see References 1 and 2): 1._ The Reference 1 Report recommends modification of drainage ,.and/or grading of public street areas and.adjacent properties to lessen damage to #2 Ranchero Road, resulting from active landsliding. No plan or engineering geology and geotechnical engineering reports were submitted. 2. An active landslide scarp transects the subject property and has removed support from portions of the garage and deck footings. Comments in our May 20, 1993 memo (copy attached), on the Flying Triangle Landslide, are directly applicable to the modifications proposed for the subject property. 4. Only the geotechnical issues (not drainage) have been considered in our comments. 3.1.

Fssures facilitate the infiltration of rain water into the slide plane which can have the effect of accelerating landslide movement. Filling fissures can also reduce the opportunities for it uries on your property. Please consider filling fissures on your property at the earliest possible = .me.
