,. POTENTIAL SEISMIC HAZARD AT TyF_ RATLIFF PROPERTY
SOUTH OF PALERMO, BUTTE COUNTY
CONCLUSIONS
Although no fault, was directly observed on the Ratliff
parcels, significant topographic, geologic, and seismic
evidence, drawn from north and south of the area, indicates
that fault zones belonging to the broader, active Prairie
Creek lineament fault zone are present,. Magnetometer
traverses reveal areas of anomalously -low magnetism in the
middle and eastern portions of the property; these are
assumed to "have been caused by fault activity, and to
indicate the locations of faults on the property. � Although
trenching is the only qday to be certain of the identity and
location of faults, avoidance (by means of setbacks for
construc'tich of dwellings) is probably a Cheaper alternative
for mitigating any potential hazard.
Besides ground ruptur& from fault movement$ the only
other si.ghif i;cant pL-ttnti al seismic hatza -d" is that o f ground
shaki rig, which can be mitigated by fol l owing the
requia Ombnts of the Uniform 8Uildiog Code. If mobile Hornet
are to be, placed on tho property, the set-up Should include
prbvisioh for resistance to lateral fdreesk

Features similar to these are 4,unund in that portion of the
Prairie Creek i.ineament fault `one mapped by Department of plater
Resources. Especially notable are the strong changes in topography
that tat^e place north and south of the Ratliff property.
The two fault maps attached to this report, shots this topographic
difference. In deciding where to position interpreted faint
locations on .a :map,, criteria that must be followed include:
placement In a manner that is justified in terms of the known
differences in topography; agreement with data from magnetometer
traverses on the Ratliff property; and agroement with geological
mapping done and interpretations made both inside and outside the
area of the map,, unless some spccifi:c evidence not to d'o so e, ists,.

the Ratliff pr OPerwty. Because the fault zone consists of
"'di scont.i nl.ious intertwined" faults, the possibility that more than
one -fault might be present at any ane location within the band must
be kept in mind. Later mapping by Busacca ( 1'90 ) shoaled the
lineament -fault zone as a line rather than a 'band, east of the
location given by Department of `Water Resources and 200 feet east of
the east bacrndary of the Ratliff property. We stated (p. 165) that
the Prairie Creek zone is Well e ---pressed and easily tra-ced" in the

might continue trending to the northwest, as is suggested by
alignment of a series of law saddles: since its e;isteice is
irrelevant to the Ratliff property, it is not analyzed -further.

Three parallel, east -trending magnetometer= traverses were made
across the property, in an effort to locate evidence of one or more
fault zones. The theory behind this approach is that repeated
movement along one or more adjacent!, parallel =Faults grinds up the
rocs; through which they pass. This granulation, sometimes coupled
with ,later near -surface weathering of the rock, produces a clay sono
that can be many feet or even tens of feet. wide. Small amounts of

The alternative to avoidance is trenching. Trenches would have
I
to he dug a few feet into the greenstone (car less if refusal is
encountered before that depth is reached). in order to be sure of
seeing the cause of the magnetic anomalies. The depth to gr-eenstone
within the anomalies is not known. but is greater than •4 feet (the
depth of the soil test pits), doep trenches would have to be shored
in order to meet worker -safety requirements. Between a.30 and 900
feet of trench would be required
,BEWRAL SEiSHIC HAZARD
Besides eupture of the around surface -from movement Altanct one of
the -faults inferred to pass thrpu4h Hif-z jWoperty, the principal
seismic hazard is from around shAkiinq from an earthquake rpt~ipinating
in the general area.

Numerous etudies (summarized by Division of Mines and (:ieology
Staff IL979) indicate that as earthquake of magnitude b..`'.i should be
considered possible anywhere in the Fobthx l l s Fault V!--LOm,-

Fal l oWi na the 1.975 earthquake, a, Consulting 8oard for Larthquake
Analysis recommended that the maximum credible e-irthquake in the
Oroville area should be considered to have a maanitudt, of 6.5 and a
peak horizontal ground acceleration of 0.6 94 This would be a
signi-ficL�►tly stronger earthquake than that of 1975. This is in
general agreement with the Seismic Element of
the General !""1 an, which
states that a maximum i n't-ensi ty of VI I I+ should be anticipated for
s=uture earthquakes in eastern Butte County. CSuch damage could range
from -Fallen chimneys or damage to loose panel, Walls in 'ordinary
masonry housing to "serious damage" to well-constructed. rei.nTbrced

SUBJECT, REPORT on Martin C, ;Ratliff, Tentative Parcel. Map on AP# 027-230-028
DATE: August 15, 1990'
`t'ktis is a proposal to divide 20,3 acres into 3 parcels, one of 10 acres and two of'
proximately 5 acres each. The ,present zoning is A-5 (Agricultural - 5 acre parcels).
Land Use Plan Map of the Butte County General Plan designates The
this area as Agricultural
Residential. There are no specific or community plans for, the area:
tlti(e the proposal appears to meet the requirements of the existing zone, the County
Subdivision Ordinance and the California Su'tydivision Map Act require that the project be
found in conformity with the County General Plan. The initial conformity report prepared:
in January, 1990, indicated that the project does not conform to the Plan, The non-
conformity was, discussed in the environmental checklistitem 8
� ).prepared. in .April; 1990,
-- Suggested mitigation measures included redesigning the project to yield two parcels of 10
acres each. This mitigation was specifically rejected by the applicant. No other mitigation
measure was offered. (The applicant did agree to two other mitigation measures and had'
I geological survey performed which was delivered to the Planning Department later),
Options at this time are to either mitigate the identified growth inducing and cumulative
impacts, redesign the project to yield two parcels of 10 acres each or prepare an EI:R that
would either identify mitigation treasures or provide the information necessary} to make a
finding of overriding concerns ,pursuant to the California Environmental Quality Act.
Preparing an 81R would probably cost several thousand dollars and take .it least an
additional 9 months;
Recommendations
Either
I. Deny the project
2, Continue the project .in order try brepare an E,I,R, _
or 3, Approve the project to result in two parcels of 10 acres each subject to the

in January, 1990, indicated that the project doesnot conform to the Plan. The non-
conformity was discussed in the environmental checklist (item 8) prepared in April, 1990.
Suggested mitigation ,measures included redesigning the project to yield. twoparcelsof 10
acres each. This mitigation was specifically rejected by the applicant, No other ynitigation
measure was offered. (Tiie applicant did agree to two other mitigation measures and had
a geological survey performed which was delivered to the Planning Department later)'.
Options at this time are to either mitigate the identified growth inducing and cumulative
impact3, redesign the project to yield two parcels of 10 acres each or prepate an EM that
would either identify mitigation measures or provide the information necessary to make a
finding of overriding concerns pursuant "to the California Environmental Quality Act:
Preparing an EiR would probably cost several thousand dollars and take at least an
additional 9 months.
Recommendation:
Either
1 Deny the project
2. Continue the project in order to prepare an 8J.1k.
or 3 Approve the project to result in two parcels of 10 acres each subjoct to the
following mitigations measures:
1i
1. Place a note 'on the final map stating; "Automatic ire Suppression
sprinkler systems shall be installed in all residential structures in
accordance- with the National, Fire Protection. Association Standard for
'tile installation .uf sprinkler systems in one and two family dwellings
and mobile homes. NFPA Standard 13D.. The purpose of the
instaXiation of sprinkler systems is for additional safety and property
protection in the event of residential fires. This installation will reduce
the demand for structural fireprotection services in those instances
where they are installed.
2. No mitigation measure is recot�irmended at this time regarding seismic
impacts. A geological survey of the property is necessary in order to
precisely located; the Prairie Creek Fault Lineament and develop
appropriate mitigation measures.
3.
Show on the fugal map no building areas as recommended. by the
geological survey:
4.a?lace a note on the Cnal m;ap stating,"Any mobile,honles on-site to be
tied down, braced; or oifionvise treated so as to resist 'lateral forces
from ground shaking.

Dear Mr„ Hronmusz
In response to
p your letter requesting that mitigation measures be
taken to reduce impacts on the aba•re referenced tentative parcel
map the owner has authorized Barnhart"ttown & Associates t0'
accept the suggested mitigation measures L and 2 as produced by
your office. However, it is felt that item one (1) is somewhat
unusual as most single family residences are not equipped with
automatic sprinkler systems,
We have also beendirected to not accept. item 3 as a mitigation
measure as this parcel does conf;pr;a to current zoning ol.P_- ar.3;
general Plan
the g P designation of Agricultural Residential, (AR),
A geologic report is currently underway at this time anfl" shall be
forwarded to your office at the time of completion.
Thank you for your time and coriiideration

Dear Mr. Ratliff.
Ari initial study of your proposed, project, a Tentative Parcel Map,
Xndittcates potentially adverse impacts to the environment (refer to the
60closed environmental Checklist). To reduce or eliminate these impacts,
suitable mitigation measures are required as part of the project
athen-vise, an 37invironmental Impact', Report (EIR) 'is required pursuant to
the California Environmental Quality Act,
An early response to this notification, sent to the Planning Department;
will expedite the scheduling of your project. Please forward your written
response within 15 days from the date of this letter.
` tants is included, These persons can determ ane: the
i
need list
for local
�tlby conducting a records search conduct geological
s subsequent tete for such surveys. In, the event of an EIR. requirement,
serve s or arran
ter will be sent outltnrig i!iie procedure for the County
to select the con-s-tltant to prepare the VEIR.

The alternative 'to avoidance is trenching. Trenches Would have
I
to "e dug a few feet into the greenstone (or less if refr.rsal is
I' :er countered before that depth is reached) in order to be sure of
seeing the cause of the magnetic anomalies. The depth to green5tone
within the anomalies is not known, but is greater than 3 Meet (the
depth of the sail, test pits). Deep trenches would haves to be shared
in order to meet wnrl>er—safety requirements. Between ciQu and 900
feet of trench would be required.
