"Dr. Miles Kenney on the development of the western Hollywood Basin and Cheviot Hills,
and newly identified blind thrust in Santa Monica Bay"
Speaker: Dr. Miles Kenney, PhD, PG
Conclusions will be presented for a local to regional
seismic hazard evaluation for the Beverly Hills Unified
School District (BHUSD) conducted by the author
from 2011 to 2016. This study was primarily
motivated for health and safety concerns due to the
antiquity of many of the existing structures at various
campuses in addition to METRO deciding to divert a
proposed subway tunnel from Santa Monica BLVD to
Constellation BLVD. The diversion placed the top of
the proposed tunnel ~50-feet beneath Beverly Hills
High School. BHUSD had valid concerns about a
potential sinkhole during construction and future
campus developments, some of which proposed to
extend underground due to limited campus aerial
extent.
Another seismic hazard arose for BHUSD from
geologic-fault studies associated with the proposed
METRO subway and their well-known retained
paleoseismologist consultants. These studies
proposed a previously unrecognized north-south
trending fault zone associated with north-south
trending geomorphic Cheviot Hills Lineament. They
mapped the proposed Cheviot Hills fault zone through
the entirety of the Beverly Hills High School campus.
However, published geologic map and local
stratigraphic and structural studies conducted by oil
companies had long mapped the east-west trending
Santa Monica fault zone in the vicinity of the northern
portion of Beverly Hills High School. Thus, at the time
of this study, there were two
"published" orthogonal fault zones potentially
intersecting in the Beverly Hills High School campus!
An important regulatory aspect of evaluating seismic
hazards at the time was that the California Geological
Survey was actively working on creating AP-Zone fault
hazard maps for the Santa Monica and Hollywood fault
zones during the time. Thus, METRO geotechnical
studies, the Kenney GeoScience study, and many fault
investigations for many properties in the BHUSD
vicinity occurred without the aid of regulatory fault
hazard maps.
The Kenney GeoScience study involved evaluating
local data to better understand the local stratigraphy
and structure in the vicinity of BHUSD, and regional
data across the entire northwestern Los Angeles basin
that included offshore and onshore geologic
publications. My presentation will provide a summary
of findings that occur within the Beverly Hills High
School campus, in the vicinity of the campus including
the Cheviot Hills and western Hollywood basin, and
more regionally focused on the east-west trending
Santa Monica to Hollywood fault zones.
Dr. Kenney has over 30 years professional experience in the
Geologic and Geotechnical industry with an emphasis on evaluating
aeolian (dune) systems, seismic hazards, fault activity and
structure, Geomorphology, kinematics, structural geology,
stratigraphy and enough knowledge about soil development to get
into trouble. He was also a college lecturer years at many colleges in
southern California. Dr. Kenney has shown the ability within
complex geologic areas to provide reasonable hypothesis and
geologic solutions using geologic fundamentals. He is currently
working as an independent contracting geologist via Kenney
GeoScience.
