RE: Erosion control, drainage and grading plan for property at # 2 Ranchero Road,
Rolling Hills DCB Job # 94-248E
Dear Al:
Attached you will find the County's response to the plan we prepared and submitted for
grading improvements and drainage upgrades for your property. 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

Inc., to Albert Martin - "Surface Drainage Conditions at
#2 Ranchero Road, Rolling Hills, CA; Job No. 93-038E".
2. March 16, 1993 letter from Alfred A. Martin, resident
of #2 Ranchero Road, to the Rolling Hills Community
Association - Surface Drainage Conditions at #2 Ranchero
Road, Rolling Hills, CA".
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.
If you have any questions, please contact Dave Poppler at

Dear Dr. Frey:
As in past years, with the approach of the rainy winter season, residents in the Flying
Triangle area are urged to fill any ground fissures which may exist on your property.
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. Should you
hzve any questions or require further information, please do not hesitar.c to contact this
office.
Sincerely,
4/44
