HomeMy WebLinkAbout77-47B 8(BEDROCK & GROUND) - The forces resulting from
ACC1JLeseismicswaves traveling through the crust of the earth
measured as a fraction times the force of gravity
(example 0.15g). Maximum accelerations are generally
higher for large magnitude earthquakes and for any given
earthquake the acceleration forces deorease with it -
creased distance from the epicenter or fault break.
ACTH,_., FAULT A :fault that has moved in recent geologic time
and which is Likely to move again in the relatively near
future. (For geologic purposes, there are no precise
limits to recency of movement or probable future movement
that define an "active fault." Definitions for planning
Purposes extend on the order of 10,000 years or more back
and 100 years or more forward. The exact time limits for
planning purposes are usually defined in relation to con-
templated uses and strictures,)
ALLUV_. L -Pertaining to or composed of alluvium, or deposited

et, al.). p (from Gilluly,
DISPLACEMENT (Geological.') - The relative movement of the two
sides of a fault, measured in any chosen direction; also,
the specific amount of such movement. Displacement in an

in recent geologic time and no evidence of potential move-
ment in the relatively near future.
INTENSITY (earthquake) A measure of the effects of an earth-
quake at a particular place on humans and/or structures
The intensity -at a point depends not only upon the strength
of the earthquake, or the earthquake magnitude, but also
upon the distance from the point to the epicenter and the
local geology at the point (AGI, 1972) .
isbSETSMAL LINE - A line connecting points on the earth's sur-
face at which earthquake intensity is the same, it is
ii.sually a closed curve around the epicenter. Syn; iso

is the logarithm, to the: base 10, of the amplitude in
microns of the largest trace deflection that would be ob-
served on a standard torsion seismograph (static magnifi-
cation = 2800 period = 0.8 sec; ;damping constant = 0.8)

occurring is great enough to be of concern. It is con-
oei.vs.ble that the maximum credible earthquake might be
approached more frequently iiz one geologic environment than
in another.

DATA INVBSTIGATION
LIMITATIONS
The seismic analysis for •the Seismic Safety Element is based
upon data obtained from geologic and seismic research. The
analysis was prepared by C'H2D4 HILL to aid in the Seismic
Safety Element evaluation. by Butte County and to assist in
the planning for that County. The mapping is intended to
indicate only general conditions and docs not depict specific
conditions at any particular site. The maps represent the
opinions of the geologist as to the presence and character
of -iaterials and the possibility of hazards, The analysis
was conducted in accordance with generally accepted engineering
geology practices and makes no warranty either expressed
or implied as to material. -,included in the report,
Theanalysisof expected. ground shaking was one of the primary
objectives of this study. The extreme variation in geologic
conditions and the lack of historical seismic information
relating to ground shaking made the ana,l.ysis extremely difficult.
The Crpville earthquake of 1 August 1954 surprised the public
and a majority of scientists, It was similar to the 1952
Bakersfield -Tehachapi earthquake and the 1971 San Fernando
earthquake: in that faults not then recognized as potentially
active were, in fact, active and p--oduced significant earthquakes.
It is a general assumption made in the selection of a design
earthquake for an area that: -the seismic history of the area
gives a reliable indication of future earthquake activity.
Because the earthquake history of the western United States
covers no more than 2uO years and because the geologic processes
that ultimately produce earthquakes cover a much longer period
of timer it is apparent that there is insufficient data to
make reliable estimates. Therefore, geologic data is used
as well as seismic history in arrivi►ag at more realistic,
predictions of future seismic activity.
GENFBAL METHOD
The investigation', conducted in November and December 1976,
consisted primarily of:.

LAND1,31LIDE, CLASSIFICATION
DEBRIS SLIDE
Debris slides or slumps are incoherent or broken masses of
rock and other debris that move downslope by sliding on a
surface that underlies the deposit. This type of :failure is
sometimes termed "arcuate" and is most common in massive;,
weak, saturated material which includes thick sections of
clay soil and poorly compacted artificial, fil7,s. The movement
of the landslide is partly rotational with the failure zone
typically described as an arc,
BLOCK GLIDE
A block glide is a landslide which has failed along an
unsupported or weak plane. The plane of weakness is usually
a bedding plane, joint plane, fault plane, erosional plane,
or formation contact. Block glides typically occur in
highly metamorphorsed igneous and sedimentary rocks which
have undergone intensive deformation and contain well-
defined joint surfaces or sheat` zones. Block gli. ies also
include layered rock of sedimentary or igneous origin which
has been dissected by stream erosion with resulting deep
canyons,
MUDVLOW9 OR EARTHFLOWS
Mudflows or earthflows consist of saturated soil mass and/or
weathered rock moving on an underlying surface of more
competent soil or bedrock. This type of Flow generally
involves rapid downslope movement of saturated weak materials
on competent bedrock. They typically originate on moderately
steep hillsides where tl^ �urface soils are well developed
and overlie poorly dra rock or soil. Mudflows are
common in areas of ip, infall, steep slopes, and
little vegetation or e vegetation has been removed
by maze or fire. Boc lows move for long distances,
they can result in cc,, damage to developments along
streams and canyons.
ROCKFALLS
Rockfalls involve the free fall of weathered rock downa,
steep slope. They sometimes form as avalanches of Loose
rock on very steep slopes with little or no vegetation.
Rockfalls are most common on slopes with gradients greater
than 50 percent and where natural weathering has produced
fractured rock with little soil cover.

11 CLASSIFICATION PR0C4DUjjBS
Fire hazard Classes were identified by combining maps of the
critical. fuel, Weather, and slope factors and using the Severity
Scale shown below. .Fuel classes were identified using'4
Department of Water Resources 'vegetation map from an Unpublished
1971 study on Butte County's economic resources and a 1976
field survey of the Paradise area. Critical. Fire Weather
Frequency classifications were determined from the Division
of Forestry report. Slopes were plotted from U.S. Geological
Survey quadrangle maps. These maps are on file at the Butte
County Planning Department.
According to the Division of Forestry report, vegetation,
weather, and ground slope are the most significant factors
which determine the intensity of a fire and the severity
of the hazard. The typeof vegetation, its density,
its condition (moisture content, size, etc.) largey determine
fire intensity and rate of ,spread. Conditions contributing
to a high intensity fire include a high fuel density, low
moisture cax�tent, incl a high proportion of large-sized wood.
Critical. weather factors invade Wind, temperature, relative
humidity, and precipitation. Wind has the greatest effect
on the rate of fire spread. Generally fires burn more rapidly
upslope than downslrope, and the rate of spread increases
with an increase in slope. Steep slopesalsorestrict accessi-
bility, increase travel time to fires, and limit the type
of equipment that can be used to control the fire

The Division of Forestry procedure shown in Figure c�j above
divides fuel, (vegetation), weather, and slope into three
classes, tach claS8 is assigned a severity factor. Multiplying
the severity factors in matrix form results in a range o
values from 1 (l;Lght grass, mildest weather, 0-40 percent
supe) to 256 (hsavy woods, most severe weather, over 60
petoent slope). These values are divided into three fire
hazard classes .. moderate, high, and extreme, As stated
in the Divigion of Forestry report, "The resulting class
designation is Logical in relation to expected fire behavior
and potential f;Ure damages. 'Three classes were also a. practical
number from the standpoint of specifying different conditions
under which Land use and development should take place in
the wildland8.11

--WEIGHTED N14TWORX, dB (A') - The sound pressures heard by the
human ear vary over a wide range, To maks this range
easier to study, sound pressures are converted into
units called decibels W), The range than groes ,from
Or the threshold of hearing, to beyond 140 dS, at the
threshold of pain.
Because the human ear does, not react to sound at low
frequencies in the same way as sounds at high frequencies,
,the quality of sound, must also be evaluated, An "A. -
Weighting Network" is provided in sound level meters
to simulate the human ear-. A -weighting sound levels
are expressed in units of dE (A) ,
.ABSORPTION - Absorption is a property of materials that
reduces the amount of sound energy reflected. Thus,
the introduction of an "absoxbent" into the surfaces
of a room will reduce the sound pressure level in that
room by virtue of the fact that sound energy striking
the room zurf'aceswill not be totally reflected. It
should be; mentioned that this is an entirely different,
process from that of transmission loss through a material,
which determines how much sound gots into the room via
the walls, ceiling, and floor. The effect of absorption
me:roly reduces the resultant sound level in the room
produco.d by energy which has already entered the room.
AIRBORNE SOUND - Sound that reaches the receptor by propoga-
tion through air.
AMBIENTe OR, BACKGROUND SOUND -- Ambient or background sound
is all encompassing sound associated with a given environ-
,ment, being usually a composite of sounds from many
sources near and far without inclusion of noise from
isolated identigiable sources.
COMMUNITY NOISE EQUIVALENT LEVEL, (CNEL) - CNEL is a scale
which takes into account all the A- Weiyi�ted acoustic
energy received at a point, from all noise events causing
noise levels above some prescribed value, Weighting
factors are i.ziclu ed which place greater importance
upon noise events occurring' during the evening hours

METHOD Off' INVESTIGATION
`n
Public agency reports and interviews with public officials
were the }primary sources of the information for the Noise
Element,. Report data were supplemented by a limited monitoring'
program in selected locations in the County to establish
approximate background noise levels.
Noise complaints were reviewed by contacting the County
zoning .i.nvestigator, the County sanitarian,'s office, the
Stat: Department of Parks and Recreation, and the City of
Chico Planning Department.
Traffic counts were obtained from the State Department of
Transportation (CALTRANS) in the form of 1975 traffic figures
and estimated annual growth rates. Traffic figures for
County roads were obtained from -the Butte County Public
Works Department traffic count maps. Noise data to comply
with the 1975 Noise Element Guidelines for State Highways
were requested but not made available.
Railroad traffic information was obtained from Western
Pacific Railroad in Crovill,e and from previous information
on the Southern Pacific Lines obtained by the Butte County
Planning Department. Measurements Caere taken of ambient
noise levels near the western Pacific maintenance and cldssi-
fication yards south of groville.
Data for the Chico Municipal Airport was obtained from the
City of Chico General Plan and from discussions with City of
Chaco staff.. 915ort noise data for the Oroville Municipal
Airport was requested but not made available. Only preliminary
projections of future noise levels were possible because of

PROCEDURES FOR 0PVIC1Ai, STA'.1ai'
DESIGNATION Or SCENIC HIGHWAYS
Y*
ELIGIBILITY
To be designated as an Official State Scenic Highway; a
State highway must be shown on the Master Paan of Scenic
Highways and listed in Section 263 of the Streets and Highways
Code. Highway 70 north of Highway 149 is the only State
highway in Butte County indicated on the State's Master'
Plan. Routes were originally included in the Master Plan as
a result of public hearings held throughout the State. New
routes can be added only by action of the State Legislature.
The State Scenic Highway Advisory Committee should be first
requested to review proposed additions and .to recommend
their inclusion into the Master Plan.. Any count=y road
classified as a scenic highway by the County's Scenic Highway
Element is similarly eligible for State designation as an
Official County Scenic Highway,
Action, The County of Butte requests their legislative
representatives and the State Scenic Highway Advisory
Committee to consider the inclusiop of all State highway
sectors proposed in the Scenic Highways Element into
the Master Paan of Sc=enic Highways.
STUDIES
The legislative body having jurisdiction over lands adjacent
to eligible State and County Highways has the responsibility
for initiation of corridor studies leading to official.
designation. For a State highway, the Board =of Supervisors
of a county muse request by resolution to the District
Director of Transportation that a corridor survey and a
highway facility study be made. The State Scenic Highway
Advisory Committee will then review the natural scenic merit
of the proposed highway sector. If the Advisory 'Committee
determines that the route has good potential for official
designation, the District Scenic Highway Coordinator of the
Department of Transportation will be so 'advised and will
survey the study. The results of the corridor
survey e
eyandhighway facility study will be summarized by
District :staff in a single Scenic Highway report. The
report will contain maps, photographs, and other necessary
documentation showings
E-1
Sugqusted sconic highway corridor 'boundaries
Sc eni.c elements within the suggested corridor
The relationship of the roadway to its surrounding
environment
* Proposed re l;ignme ,ts or improvement.s of the route
* Potential locations of roadside rests, vista
points, and areas for public or commercial infor-
mation sites
The report will be prepared in cooperation with local govern-
ment. staff. As early as possible, the local jurisdiction
should solicit the help and advice of local citizens' corn-
mitte0s, affected property owners, conservation groups and
anyone else who might be interested in `the proposed designation.
Early involvement of citizens and ample time for review and
comment will result in corridor .boundaries which reflect
local desires and reduce the possibility of last minute
controversy.
The procedure for Stat,;: designation of official al County
scenic highways requires that the local government initiate
and conduct the corridor survey and highway facility study
and propane the Scenic Highway Report.,
Action. The Board of Supervisors requests that a
Scenic Highway Report be prepared for each eligible
State and County highway in Butte County. County staff
assists in the preparation of reportsand solicits the
assistance of all interested parties
CORRIDOR PROTECTION PROGRAM
Upon completion and approval by involved parties, the Scenic
Highway Report is used by the local jurisdiction in the pre
paration of a local scenic corridor protection and enhancement
plan and program. The local program should provide for the
protection and enhancement of the existing natural and man
made scenic resources that helped qualify the highway as
eligible for designation and that are described in the
Scenic Highway Report. Thth,minimum requirements which must
be met by the local jurisdiction include:
Regulation of land use which may include density
and/or the intensity of development
Detailed land and site planning
B-
a control of outdoor advertising
Careful attention to and control of earthmoviAq
`+ and landscaping
Design and appearance of structures and equipment
Action. The County adopts a program of regulations and
standards as a "Corridor Protection Program".
STATE APPROVAL
The local scenic corridor protection program should be
reviewed by the District; Scenic highway Coordinator during
Preparation for its fulfillment of State guidelines. Upon
adoption, the local Program should be sent to the District
Coordinator along with a written request for official desig-
nation. He Will then forward to the Department Of Transpor-
tation Headquarters the program and roquest along with his
comments and the Scenic Highway Deport. Headquarters staff
next reviews the written materials and calls a meeting of
the Scenic highway AdvS scary Committee.
The CQi' mit:tee. consists of seven members appointed by the
Governor from among local officials, persons competent: in
landscape architecture, scenic conservation .and planning,
and park problems.. Their: duties are to counsel the Transpor-
tation Department concerning standards for scenic highways
and the actual designation of Official State and County
Scenic Highways. After review of the proposed designation,
the Committee sends their: findings and recommendation to the
Department Director, if and when the Director determines
that: the local corridor protection program has been implemented
by local government: agencies, he declares State highways to
be Official State -Scenic Highways and authorizes loca],
officials to declare County roads as Official County Scenic
Highways.
Action, The County requests review by CALTRANS during
preparation of the corridor protection programAfter
adoption of measures to implement the Corridor*.protection,
Program, the County requests State approval of the
program and official state designation.
BENEFITS
The State Transportation, Department must indicate designated
scenic highways in any documents: or maps issued to -the
public.. Maps distributed by the California State Automobile
Association and some oil companies also show designated
scenic highways
