ARIA COUI 716 to 61171
The City of Ontario Planning Department would like tv protest the proposed do=
volopment or a calcium rarbonato (limestone) plant on thn south aide of Eighth
Street between Milliken Avenue and Rochester Avenue.
The Planning Department docu not think it is in the beat interests of both
Ontario and Rancho Cucamonga to allow a use ouch as has been proposed which
will be vioable to the travelers and local residents alike from the eluvoted
Dovore Freeway.
Both cities are attempting to draw industrial uses of high qunlity nonpolluting
types which will increase the job inventory and increase the real propocty
valuation. It is not apparent to the City of Ontario how these goals can be
reachad with a limestone processing plant which has inherent in its process the
crushing and grinding of limestone. Particulate matter must rise in the air,
due to the processing, which will further obscure the visibility of the area.
We urge you to select another site if this type of use is allowed in Rancho
Cucamonga. Ontario's ordinances prohibit such uses in the industrial zones.
We than). you for your consideration of our comments.
Very truly yours,

CERTIF'ICt :' ION OF A FINAL EIR
0
Ilia following discussion is provided to inform the Commission on the procedures
and issues related to certification of a final EIR.
The provisions of tl:e California Environmental Quality Act (CEQA) require the
decision- making body to certify that the final EIR has boon completed in compliance
with CEQA and the State EIR guidelines. In addition, the certification shall certify
that the decision- making body having final approval authority over the project Ilan
reviewed and considered the information contained in the EIR prior to the approval
of the project.
The major finding of such a certification is that the final E1R adequately addresses
the environmental consequences of the project. The State EIR guidelines state that
the EIR should be prepared with a sufficient degree of analysis to provide decision -
makers with enough information which enables them to make a decision. An evaluation
of the environmental effects of a proposed project need not be exhaustive, but the
sufficiency of an EIR is to be reviewed in the light of what is reasonably feasible.
Disagreement among experts does not make an EIR inadequate. The courts have not
looked for perfection but for adequacy, completeness, and a good faith effort at
full disclosure.
If the Commission feeln that the information contained in the EIR in sufficient
to allow a decision to be made on thopproject, then the Commission can make the
necessary findings to certify the final EIR.
Respectfully submitted.

STAFF REPORT
Date: November 199 1979
To: Planaing Commission
From: Jack Lam, Director of Community Development
Subject: FINAL EIR FOR THE PLUESS- STAUFEIt FACILITY
DACRGROUND: The Final EIR has been completed for the Pluess- Staufor Project
and is enclosed for your review. Responses and comments on the draft EIR
ware received from six agencies:
.City of Ontario
.California Regional Water Quality Control Board - Santa Ana Region
.Chino Basin Municipal Water District
.Foothill Fire District
.South Coast Air Quality Management District
.California Air Resources Board
The significant issues addressed in the EIR focused upon circulation, drainage,
public facilities and services, air quality, and aesthetics. As a result of
the comments received from the above agencies, the project has been modified
to further mitigate the impacts of the proposed project. ,
EVALUATION: Following is a summary of the analysis and conclusions of the
Sections within the EIR.
*Circulation: The major concern wan whether Seventh Street, could be deleted
from the General Plan and an additional east /west adequate thoroughfare provided
through the industrial area. Upon completion of a traf£icway study by the City,
the General Plan was amended to delete Seventh Street and upgrade Sixth Street
as a secondary and special boulevard. Therefore, the circulation issues have been
resolved.
*Drainage: The subject site is not subject to major flood problems. Ordinance
No. 24 which establishes regulations in accordance with the Department of Housing
and Urban Development Flood Insurance Program will be complied with.
*Public Facilities and Services: Utility Services do not anticipate problems
with providing adequate service to this project. The mitigation measures proposed
should be adopted as conditirns of approval. The Fire District has stated that
there is minimal impact on fAre protection for the proposed development. However,
because of extended response times, medical emergency services are impacted as
outlined in the Fire District letter dated April 24, 1979.
® *Air Quality: Because of the present air quality problems of this basin, air
quality is one of the major issues of this project. The original impact calculated
as a result of this project would have increased total pollutants to less than six
tenths of a percent for the Pomona- Walnut Valley area and less than two hundreths of
l'f�M A
a percent increnao over the County. Since the writing of the Draft EIR, the
project linn been revived to down -nird the, fuel fired proccquen which resulted "
in a decrenno to 45 percent of the iritinl qunntity of all air pollutants combined.
The total pollutants produced comprise a 0.034 percent increana over the present
eminnionn inventory.
++Aeathotices Because of the type of equipment m,ed for thin operation, it is
difficult to provide complete acreening for such operations. However, the acatho-
ties can be substantially increased by use of earth berme and landscaping.
The final EIR has addressed all the significant issues relative to thin project
and it complies with the provisions of CEQA and the Sbate EIR Guidelines. All
comments received on the Draft EIR have been adequately addressed in the Final EIR.
RECCMMENDATIONi It in recommended that the Comminsion adopt Resolution No.79 -69
which certifies the Final EIR.
Respectfully submitted,

STAFF REPORT

To: Planning Commission
Prom: Jack Lam, Director of Community Development
Subject: DIRECTOR REVIEW NO. 79 -32 - PLUESS- STAUFFIt - The development of a
limestone grinding and processing plant located on 00 acres of lend
in the M -2 zone, on the north aide of Sixth Street, 1,20' went of
Rochester
DACKGROUNDt Pluess- Staufer, Inc. is requesting approval to develop a limestone
processing facility located between Eighth and Sixth Streets and Milliken and
Rochester (Exhibit "A"). An EIR Iwo been prepared for thin project which fully
outlines the details of such facility. Prior to reviewing the site for final
approval, the Commission will first have to certify that the final EIR adequately
covers all possible significant adverse impacts on the environment.
EVALUATION: The mitigation measures outlined in the Final EIR have been incor-
porated as conditions of approval for thin project to insure that potential
significant impacts are reduced to an acceptable level.
Approval of thin project will require full dedication and constructiun of Sixth
Street in front of the subject property. In addition, 40' of dedication and 26'
of paving for Sixth Street will be required from the east property line to Rochester
Avenue. This is in accordance with the Planning Coemission access policy. I:, addi-
tion, the applicantu will be responsible for one -half the cost of an irrigated
landscaped median down Sixth Street.
In addition to the mitigation measures, Staff recommends that six (6) foot high
landscaped earth berme be used along the cast and went property lines, along the
north aide of the facilities, and alc,ng the Sixth Street frontage. The landscaped
earth berms are recommonded in order to mitigate wind currents and turbulances
caused by normal afternoon winds and Santa Ana conditions. In addition to miti-
gating wind conditiono, the berms can act no visual screens for the project.
The landscaped berms will help screen outdoor storage and machinery. Refor to
Exhibit "E" for recvmmended locations of earth berms. Therefore, the berme will
provide both visual and wind barriers. In accordance with Special Boulevard land-
scape standards, the development will require a 35' deep landscaped and irrigated
strip across the entire Sixth Street frontage. All landscaping and earth berms
shall be provided throughout the project with the first phase construction.
Exhibit "C" displays the proposed grading plan. Exhibits "D -?" are enlargement
details of the site and proposed a^t,slopment. Exhibits "G -11" display elevations
of buildings and ailos.

FINAL ADDENDUM SUMMARY
y
Other environmental concerns included aesthetics. traffic
and fire protection.
The agency letters followed by the Responses to Comments
are presented following this Summary. The Draft EIR text
follows the Responses to Comments for reference.
This Final Addendum to the Environmental Impact Report for
the Pluess- Staufer Calcium Carbonito Processing facility
has boon prepared to respond to comments by various public
agencies concerning the proposed project and the !craft
EIR. Those agencies are as follows:
City of Ontario
California Regional Water quality Control Donrd - Santa
Ana Region
Chino Basin Municipal Water District
Foothill Fire District
South Coast Air quality Management District
California Air Resources Board
The environmental issues raised by these agencies pri-
marily centered upon air quality and water quality. As a
result of these comments, the proposed project hos been
modified to further mitigate the proposed project. For
oxampla, the production capacity of the plant has been
•
reduced which decreases air pollutants. ilia air quality
analysis has been revised to include 1978 data and on -site
emissions have been down - graded. In addition. emissions
from rail operation3 have been calculated. The water
quality analysis now includes types and volumes of waste -
water effluents.

Comment 5
Tile efficiency and roliability of dust collectors and dust
suppression systems should be provided.
Response 5
The project engineer has indicated that the reliability of
both the wet dust suppression system and the bag house
dust collector should be considered excellent. The ox-
pected bag house dust collector efficiency �s 99.99X. The
expected wet dust suppression system overall efficiency is
99.99 %. This efficiency has been calculatou from tiie sup -
of becoming

revisions have eliminated the electrostatic Recant process
The expected fan collectors' precipitators%
to 95 %. Every cyclone is backed cup with o of bag houses dust
collector with 99.99% efficiency.
Comment G
Stationary on-site emissions will affect Ontario due to
Santa Ana wind conditions.
Response G
Santa Ana wind conditions are experienced in the project
area intermittently, generally between November and March.
Wind direction is from the northeast and east, usually
accompanied by high velocities and turbulence at ground
levels. The effects of Santa Ana wind conditions on the
project area would be to create short -term high particu-
late emissions (primarily fugitive dust on -site) with
highest concentrations immeaiately down wind of the pro -
ject site. Due to turbulent mixing, concentration of the
particulate plume decreases as the pollutants travel
southwestward. The impacted. areas are those areas of
Rancho Cucamonga, Ontario and Upland near the site. The
degree of impact is considered significant, however, due
to the short -term, intermittent nature of these condi-
tions, the overall impact is minor.
Comment 7
Transportation systems should be enclosed to reduce fugi-
tive dust.
Response 7
The project engineer has indicated that the transportation
systems such as belt and screw conveyors will be enclosed.

SUBJECT: GENERAL PLAN AMENDMENT - CIRCULATION ELEMENT INDUSTRIAL AREA
As a result of development in the industrial area bounded by Haven Avenue and
Rochester Avenue and Fourth and Eighth Street. The City requested that the
Industrial Area Specific Plan consultants study a potential General Plan
Amendment to the Circulation Element that dealt with the following issues:
1. The elimination of the Seventh Street precise alignment.
2. Abandonment of Eighth Street.
3. Reclassification of Sixth Street from a Collector to a
Secondary Highway.
The report concludes, based on a capacity balance analysis for a long range of
proposed uses:
1. Seventh Street can be eliminated.
2. Eighth Street can be abandoned.
3. Sixth Street should be reclassified.

The Board staff has reviewed this DEIR for a proposed
calcium carbonate processing facility in the City of
Rancho Cucamonga. The DEIR should state the estimated
volumes and types of wastes that are proposed to be
discharged to both the Cucamonga County 4iater District
sewer and the lined settling ponds.
As stated in the DEIR, the settling ponds will require
waste discharge requirements (i.e., a permit) from this
Board. An application for these requirements must be
submitted to th,s Board at least 120 days prior to the
initiation of tF,e proposed discharge.

Comment 1
What are the estimated volumes and types of wastes that
are proposed to be discharged to the Cucamonga County
Water District sower and settling ponds.
Response 1
Three waste effluents will be associated with the proposed
protect. The first affluent is waste treatment effluent
from the settling ponds. This discharge involves 15,000
gallons per day (ppd) with a composition of 200 mg /l (mil-
1 igrams per 11 ter) of total suspended sol ids (calcium car-
bonate and silicatas).
The second affluent is cooling tower blowdown. This
involves 3000 gpd of typical cooling tower treatment chein-
,icals. (no' chromates). The third effluent is typical sani-
tary wastes. The estimated volume is 3000 gpd.
It is expected that all effluent can be discharged to the
Cucamonga County Water District sower.

As the Draft EIR indicated, Chino Basin Municipal Water District
could be involved in the project as it relates to the handling
of wastewaters produced with respect to both the quantity and
the quality of wastewater. Since excessive amounts of limo and /or
salts would preclude discharge to the domestic system, use of
the non- raclaimable waste system may be necessary. Chino Basin MWD
would therefore like to emphasize the need for review of the quality
and quantity factors of the wastewater well in advance or Pluess-
Staufer proceeding with construction. This prior review 1�rill enable
the District to determine sewer availability and the condition
under which the sewer service would be extended.

RE: ENVIROMIENTAL ItIPACT /TIRE PROTECTION
PLUESS— STAUrER (CALIFORNIA), INCORPORATED
LIMESTONE PROCESSING FACILITY
Dear Mr. Vairin:
With the present information available and submitted, we
are unable to determine the true environmental impact on
fire protection for the above proposed facility. To assist
this agency in making nn int311igent determination on the
environmental itopact, it will be necessary to have addi-
tional quontions answered.
A letter
containing the following information should be
■1
submitted
as soon as Possible, and must be detailed - not
general
statomonts.
1.
Type of machinery and equipment used.
2.
Are hazardous chemicals used in conjunction with
any of the operations? IL so, what type?
3.
Are cryogenic fluids used in conjunction with any
4.
of the operations? If so, what type?
Are flammable gases usedin conjunction with any
of the operations? If so, what type and what
are the flash points?
5.
Ara flammable or combustible liouidn used in con -
junction with any of the operations? If so,
provide the following information:
a. Flash and boiling points.
b. flow dispenned.
c. flow stored (inside or outside).
d. Amounts stored, size of containers.

It is our feeling, based only on the limited information
{� submitted to d.zte, that there would be a minimum impact on
�! fire protection for Lire proponed development. However, there
could possibly be an ineroase on the emergency medical demand
to serve the project.
Our abilities to service the proposed project would be
greatly enhanced if the proposed station waa built and
manned. If the project is approved, they will have to

materialss
a. What is the commodity stored?
(1) How is it packagol?
b. Method of storage
0
(1) Racks, pnllotn or solid piles.
(2) Height of storage.
(3) Width of racks or storage.
(4) W1,dth of nislos.
At the pretseut time, our Station 03 would be the first -in
fire company to servo the proposed project. Their ronponse
time would be between 4 -5 minutes, with a total t_avol
distance of approximately 3 miles.
The necond -in fire company would be Station A2. Their response
time would be between 5 -6 minutes, with a total travel distance
of approximately 4 miles.
The third -in fire company would be Station Olt with a responso
time of 7 -0 minutes and a total travel distance of approxi-
mately 6 tnsless.
ror a "stoppage of breathing" incident (due to the response
time of 4 -5 minuton), there would be minimal chance of a
"nave" or survival unless artifieal rospiratiou or cardio-
pulmonary resuscitation was commenced prior to cur arrival.
This
district does have plans for nn additional station to be
located within one mile of the proposed facility; however,
due to the passage of Proposition 13, it will be quite some
time before this will be built or manned.
It is our feeling, based only on the limited information
{� submitted to d.zte, that there would be a minimum impact on

could possibly be an ineroase on the emergency medical demand

riode, with appropriate mitigation
Natural gas fired processes were rodesA gned after the ini-
tial preparat`en of this environmenta't impnct report. The
type of flash dryer initially specified was changed to a
down - sized, more efficient model with approximately 12„ of
the heat (and therefore, fuel) required. There was also a
change in the proportions of materials requiring drying,
such that the quantity ;,f materials processed through
these dryers is only 20% of the initial amount. Addition-
ally, the exhaust gasses from the dryers and heaters will
be filtered through a bughouse so that the estimated natu-
ral gas -fired emissions will be as follows:*
NOx - 1.04 lb /hr (25 ib /day)
Sox - 0.0063 lb /hr (0.15 lb /day)
CO - 0.167 tb /hr (4.0 lb /day)
Particulates - 0.00008 lb /day (0.002 lb /day)
as compared to the previous emissions of:
NOx - 6 lb /hr (144 lb /day)
Sox- 0.05 lb /hr (1.2 lb /day)
CO - 1.0 lb /hr (24 lb /day)
Particulates - 0.6 lb /hr (14.4 lb /day)

With regard to fuel oil firing during natural gas curtail-
ment, the proposed Nroco'ssing facility will �e subject to

month of the year except Janu:.,,. January's curtailment
is oxpectod to include 36% of the month. Thls amounts to
eleven days per year of natural gas curtailment.
Emissions in the fuel -oil fired mude (i.e., during cur -
tailmont) would be as follows for Number 2 fuel oil: **
NOx - 1.75 lb/hr (42 lb/day)
bOx - 2.9 lb /hr (69 lb /da
CO - 0.4 lb /nr (10 lb /day
HC - 0.08 lb /hr (2 lb/day
Particulates - 0.00017 lb/hr (0.004 ib /day)
These emissions are expected to occur only eleven days per
year.

Page 40 refers to mitigation measures which may be incor-
porated, They should be, espe4ially
those which will re-
duce NO;► and pa- i'cuTate emissiuns.
Response 3
Additional mitigation measures could be incorporated into
the project; however
some would require significant
changes in the processes with accompanying high mitigation
costs. The project is expected to have an AQMD permit re-
quired for operation and additional mitigative measures
may be required at a later date prior to permit issuance.

Subject Draft Environmental Impact
Report for the Proposed
Pluess- Staufar Calciur:
Carbonate Processing Plant
in the City of Rancho
Cucamonga SCH #79090518
Pluess-Staufer, Inc. proposes to construct and operate a calcium carbonate
crushing, grinding and processing plant on 00 acres in the City of Rancho
Cucamonga. Precrushed rock will be received from remote quarry operations
in ra +1 hopper cars, unloaded and conveyed to a large outside storage pile.
Once processed, the finished product will be shipped in bags, bulk and bulk
slurry in rail cars and trucks.
Recomnendations
The Draft Environmental Impact Ri
revised to include:
1. An estimate of the emissions
21 An estimate of the potential
Heatc -s and the Flash Dryers
!port (DEIR) is deficient and should be
from the locomotives serving the facility;
emissions from firing the Roller Mill Air
with No. 2 fuel oil; and,
4 3. A recalculation of the particulate emissions attrib•Ited to wind erosion.

Discussion
The rucomendatinn3 were made pursuant to S12ction 15113 (a) of the state
EIR guidelines. This section requires that each EIR include a discussion
of the significant environmental effects of the proposed project.
Emissions from locomotivescan represent a substantial portion of the emissions
from the project and such emissions should be addressed in the DEIR. In fact,
such emissions are also requirid to be identified and mitigated under the
South Coast Air quality Management Districts Rule 213 (Ibiw Source Review).
Since worse case conditions should be con= idered while performing an air
quality analysis, the notential impart of burning Mo. 2 fuel oil as backup
to natural gas should also be considered. In the calculation ')f wind blown
dust, it was assumed that wind blows a total of only three months during
the year. This assumption does not seem realistic. Unless the assumption
can be suppnrted with factual data, another estimate should be computed
to reflect a more realistic assumption.

In addition, thr comparison of the emissions from the proposed project to
the total emissions from the Pomona- Ualnut Valley are Vary misleading.
Since a serious air quality problem already exists in this area of ti►e
South Coast Air Basin, any increase in emissions could exacerbate a health
hazard to residents or this area. Tile comparison made in the OEIR tands
to give the false impression that the emissions from this project are
so minor that the decision makers and the public need not consider them
potentially harmful.

RESPONSES TO COMMENTS
Comment 1:
The Draft Environmental Impact Report (DEIR) is deficient and
should be revised to include: an estimate of the emissions
from the locomotives the facility.
Response 1:
According to information supplied by the project sponsor,
approximately 609000 tons per year of 500 rail cars per year
will be shipped an average distance of sixty miles one way to
serve the facility. Assuming a total haul and return distance
of 120 miles, the total tonnage shipped per year is 7,950,000
ton - miles. From fuel consumption rates 1/ this equates to
36,130 gallons of diesal fuel per year.
I
From Table 3.2.2 -1 Average Locomotive Emission Factors Based
on Nationwide Statistics, AP -42 the omissions ncurring offsite
for locomotives will be as follows:
Pollutant Emission Factor quantity Produced
Particulates 25 lb /1000 gal 900 lb /year
Sulfur Oxides 57 lb /1000 gal 2050 lb /year
CO 130 lb /1000 gal 4,690 lb /year
HC 94 lb /1000 gal 30390 lb /year
NOx 370 lb /1000 gal 13,300 lb /year
Aldehydes 5.5 lb /1000 gal 190 lb /year
Organic Acids 7.0 lb /1000 gal 250 lb /year
Total of all air pollutants a 67.9 lb /day from locomotives
Comment 2:

I. SUMMARY
This Uraft EIR has boon. proua red .to analyzu' the potantial
iinpacts of the construction and operation of a calcium car -
bonato crushing, grinding and procassin )last in the City
of Rancho Cucamonga. This facility w 1� be built on an
00 -acre parcel but w111 only utilize approximately GO
acre r•. Tire proposed facility will operate 7 days a weak,
24 hLurs a day.
Tho project impacts are briefly summarized below. The com-
plate analysts may be found in Section III.
The proposed project will alter the planned circulation
m
system for the industrial area of the Cit;1. The project
ICI
Sponsor has requested the deletion of Seventh Street
through the site and the closure of Eighth Street. A traf-
fic study prepared for the site has indicated that this
should not result in adverse traffic conditions if another
east -west thoroughfare (preferably 5Ivtlr Street) is
provided.
The project site is not sub 'lect to mejor flood problems.
The site does experience sheet flow flooding and 1s a des-
ignated floodplain. This will be mitigated by conformance
with City Ordinance No. 24.
The proposed project will utilize tiro following public
facilities and services: water, wastewater, electricity,
gas and telephone. These utiIitias have indicated they do
not anticipate any service problems.
The project site and surrounding region experience f, iquent•
high levels of air pollutants. The implementation of the
proposed project will impact air quality in three ways.
First, there wilt be an incremental increase in motor
vehicle ,related pollutants. Second, there will be emis-
sions from on -site stationary sources. The third type of
emission is off -site indirect stationary sources. The pro-
posed project incorporates design features to mitigate air
quality Impacts
The
overall impact to air quality amounts to less than six
tenths c,t' a percent increase for the Pomona.-Walnut Valley
area and less than two hundredths of a percent increase for
the County.
Aesthetically, the majority of facility operations are en-
closed in ' uildings and will not be viewed by the public.
With the closure of Eighth Street, the only public view
will be from the proposed Sixth Street. The primary view
from this location will be the office building, processing rA1
buildings and landscaping.

The City of Ontario Planning Department would like to protest the proposed do-
volopment of a calcium carbonate (limestone) plant on the south side of Eighth
Street between Milliken Avenue and Rochester Avenue.
The Planning Department does not think it is in the beat interc,ste of both
Ontario and Rancho Cucamonga to allow a use such an hue boon proposed which
will be vinoble to the travelers and local residents alike from the elevated
Dovore Freeway.
Both cl.ties are attempting to draw industrial uses of high quality nonpolluting
typen which will increase the job inventory and increaso the real propnrty
valuation. It is not apparent to the City of Ontario how tllena goals can be
reached with a limentonu processing plant which has inherent in its process the
crushing and grinding of limestone. Particulate matter must riao in tho ai.r,
due to the processing, which will further obscure the visability of the urea.
We urge you to select another site if this type of use in allowed in Rancho
Cucamonga. Ontario's ordinances prohibit such uses in the industrial zones.
We thank you for your consideration of our comments.
Very truly yours,

supply the size reduction equipment. Depending on the
desired final product, the rock will be processed through
two or more size reduction operations. The resulting
powders will be segregated by particle size in classifica-
tion equipment and stored in large product silos. Proces-
sing equipment will be enclosed in buildings.
Some rock will have naturally occurring im�rurities removed
by a beneficiation process prior to the final size reduc.•
tion steps. Finished products will be shipped in bulk and
bags by rail cars and trucks and also as bulk slurry.
Particulate emission control will be by wet suppression in
the rock receiving and storage pile areas and by bag house
dust collectors in all other areas. Waste from the bene-
ficiation process will be settled in ponds and the efflu-
ent discharged to sewers.

The finished product will be shipped via rail and truck.
The site is crossed by a 40 foot wide easement to the
Metropolitan Water District. The construction of a rail-
way spur track over the pipeline located in the easement
may require a protective slab. This issue is currently
under investigation by the Metropolitan Water District of
Southern California.

CIRCULATION
Environmental Satting
An Industrial Areas Specific Plan is being prepared for
the City of Rancho Cucamonga under the sponsorship of the
Industrial Committee of the Chamber of Commerce. A major
portion of the Industrial Areas Specific Plan is being
devoted to circulation issues. The Industrial Areas
Specific Plan is schodulod for completion approximately
July, 1979.
As part of the Industrial Areas Specific Plan, a Priority
Trafficways Study has been prepared for the Pluess- Staufor
industrial facility by DeLeuw, Cather and Company, the
traffic consultants for the Industrial Areas Specific
Plan. A complete version of this Priority Trafficw
Study may be found in Appendix C. ays
Figure 10 portrays the City's proposed General Plan and
circulation system. The proposed General Plan portrays
the extension of Seventh Street.
The project proponent has requested that tine planned ux-
tension of Seventh Street through the site be deleted. In
addition, the project proponent has requested. that Eighth
Street be closed adjoining the site.

site. The street is two lanes wide and generally is in
Poor condition. It is three to five feet belotr the grade
of the railroad track, thus forming humps at every inter-
section with cross streets. At several of these inter-
sections, sight distance is severely restricted for
vehicles on Eighth Street and for northbound vehicles on
the cross streets attempting to turn left onto Eighth
Street. Eighth Street. also has several flood control
channel crossings at grade. Spur tracks cross Eighth
Street to serve industries to the south.
Seventh Street is constructed east of Rochester and has an
undercrossing at the Devore Freeway.
Sixth Street presently terminates at Haven.

2. Sixth Street proposed to be upgraded to a special
boulevard, designed as a secondary highway (88' RW)
from the west City 1lmits to Haven a rid ,'daslgned as a
major divided highway (120' RW) betweon ilaven and
Rochester. It will go through to Rochester and also
curve northward to connect with Seventh Street.
Project impact
The potential impact of the pro j ect proponents' request to
extension
W
W
Street will beetoi limit through east -wostn circulation
the industrial area between Arrow Highway and Fourth
Street.
To determine
this impact, the priority Trafficways Study
focussed on five
questions followed by their analysis:
1. Can Eighth Street be closed without causing congestion
or disturbing network continuity?
Thera are no apparent reasons why Eighth Street
shouldn't be closed and there
appears to be general
concensus that it should be. However, the needs of
property fronting Eighth Street tn
studied furherbefore h be
segments losedca
be determined and the timing of the closures can be
recommended.
To act as an east -west thoroughfare, Eighth Street
would have to be brought up to
standard. This would
involve raising its grade three to five feet, signal-
izing all intersections with major cross streets
(including railroad
pre -empt at $10,000 to 3200000
cost penalty), installation of flashing lights and
possibly location gates si each
) and building several t l
bridges�0o0vert flood
control channels. Such a costly project is not
war-
ranted because equivalent, if not better, east -west
traffic service can be
provided by Sixth or Seventh
Streets. Continuity at the east end is not an issue
because Eighth Street does not cross the Oevore Free-
way. Continuity at the west end can easily be pro-
vided by a connector
ruad parallel to Cucamonga Wash,
between Sixth or Seventh Street and Eighth Street.
If Eighth is closed and Sixth or Seventh Streets do
1
not run through, east -west continuity will be im-
paired, leavin no through streets between Fourth and
Arrow
Highway about 8,000 feet).
2. Can ,;eventh Street be deleted without causing conges-
tion or disturbing network continuity?
With the closure of Eighth Sti -eet, Seventh Street
would be the logical alternative for an east -west
through street because it has
an undercrossing at the
i8
.
Devore Freeway and 1s approximately halfwa;, between
Fourth Street and Arrow Highway. A Precise plan for
Seventh Street between Vineyard and Etiwandi Avenues
was prepared in 1972 and has been adoptoi by the
County and the City. It would be logical, bit not es-
sontial, to extend Seventh Street east to Milliken, if
l o
throuilh street,Sev nth would e
uld function as acollector
street in place of Eighth Street.
3. Now should Sixth Street be developed in too event that
all or portions of both Seventh and Eighth Streets are
abandoned?
If' both Seventh and Eighth Streets are closed, Sixth
Strl:ot becomes tiie only potential through east -west
arterial connection. If Seventh is not bui 't, Sixth
should extend at least to Rochester. Three alterna-
tives for a through connection warrant consid•iration:
a. A "T" intersection with Rochester reyuirii'g a left
and right turn to jog up to the Sevent i Street
alignment and the Devore Freeway Undercrossing.
To provide additional capacity on Rochester to
handle the offset intersections, Rocheste, should
be widened to 64 feet curb -to -curb between Sixth
and Seventh Streets, with transition a6eas at
either end.
b. Build a ' "West Rochester" parallel to Rochester
between Sixth and Seventh Streets, but ab tut 800
feet to the west. Rochester would not need to be
widened.
c. Build a curved road connecting Sixth Street to the
Seventh Street undercrossing, eliminating turning
movements and allowing 40 mph traffic flow. This
shaped the sizes, butacould cutworketing
e
tlittl
disruption if property owners are willing t�
cider trades. + cone
•
4. What provisions are needed for truck access to the
regional freeway system?
Industrial development in the area will generate truck
trips mainly to the San Be!nardino Freeway. Truce ac-
cess to the Pluess- Staufer site can be via Rochester
from the cloverleaf at Fourth Street and Devore i'ree-
;•, way, but trucks destined to the San Bernardin) or
Pomona freeway probably will not use the Devore 1'ree
way. When Milliken Avenue is extended north to Sixth

-- Eighth Street can be abandoned.

Seventh Street should be extended westerly to connect
to the new connector, which should
be built to Second-
ary Thoroughfare standards.
If the connection is not built, Hellman would carry
the through traffic between Sixth
and Eighth Streets.
This would exacerbate the already dangerous sight dis-
tanco problem
at Eightil Street and Hellman especially
for left turning vehicles. With the
connector road in
Place, :ighth Street could be abandoned east of tiro
connector and the

In summary, the Priority Traffict+ays Study for the
Piuess- Staufev site concluded the following:
-- Seventh Street need not be continuous through tine
Pluess- Staufer site.
-- Eighth Street can be abandoned.
- -An additional east -west roadway is necessary between
Arror Route and Fourth Street.

r fe+e�sie ®�
-Sixth Street is the most logical oast -west con -
noctor. It should be connected to Eighth Street at
the west and and to Seventh Street at Rochester at
the east end. Until the traffic model for the
Industrial Area Specific Plan is in operation and
available for more precise analysis, any development
approvals should provide for dedication of a 116
foot right -of -way allowing six moving lanes (includ-
Ing 16 foot lanes adjoining the curbs) and a contin-
uous turn lano. If the model indicates that no more
than four lanes are likely to be needed, the right -
of -way could be narrowed to 92 feet. Additional
right -of -way should be provided It intersections
with major north -south streets to allow for future
double turn lanes that may be needed.
- -Throe alternative connector alignments are possible
at the east end of Sixth Street. A direct connec-
tion or a . "West Rochester" are preforrable to a
widened Rochester for access, traffic operations,
capacity and safety reasons.
The
Planning Commission has concurred with these findings
and
has recommended to the City Council that:
1.
Seventh Street to be deleted between Turner and
Rochester.
2.
Sixth Street proposed to be upgraded to a special
■
boulevard, designed as a secondary highway (88' RW)
from the west City limits to Haven and designed as a
major divided highway (120' RW) between Haven and
Rochester. it will go through to Rochester and also
curve northward to connect with Seventh Street.

DRAINAGE/FLOODING
Environm -ntal Setting
Figure 11 portrays the 1969 flood ovorflow map for the
City, the industrial area
and the project site. Tile 1969
flood overflow limits indicate the major flood problems in
the
area. the project situ does not have a major flood
problem according to a flood study
performed for the
Industrial Areas Specific Plan (see Appendix D).
11owever, the project site and the entire industrial area
is subject to sheet flow flooding is
and a designated
floodplaln by the U.S. Department of Housing and Urban
Development. The
potential exists for a one -foot inunda-
tion for a 100 -year flood as designated on the 11U1)
flood
map. The railroad tracks on the northern boundary of the
project site
act as a dam for Sheet flooding.
Project Impact•
I
The flood problem study prepared for the Industrial Areas
Specific Plan (Appendix U) indicates
the project site does
not have a major flood problem and the deletion of Sixth.
Seventh or Eighth Streets
would not have any significant
affect on drainage. Because of the north -south flow
of
drainage and until such time as a storm drain system for
the area is provided, the north -south
street system is
important and necessary for conducting both on -site and
off -site drainage flows
southerly.
In addition, Cit Ordinance No. 24 establishes regulations
in accordance w th the Development
of Housing and Urban
Development Flood Insurance Program. This ordinance
re-
quires development to incorporate flood contral protection
measures into development
plans.
There may or may not be local drainage problems associated
with development runoff and
Str at drainage in the indus-
trial area. This type of drainage problem can only be
mitigated by the development
of an adequate storm drain
system in conjunction with drainage flows
carried in
streets, according to the flood problem study (Appendix
Mitigation Measures
Conformance of the proposed project with City Ordinance
No. 24 Establishing Regulations In
Accordance With The

Water and Wastewater
Water and sewer service to the site will be provided by
the Cucamonga County Water District. Wastewater disposal
may 'also be provided by the Chino Basin Muncipal Water
District. There is no existing service to the site.

Southern California Go Company and General Telephone
Company of California, respectfully.
Project Impact
Water and Wastewater
Water service to the project site will require the exten-
sion of an existing transmission main in Sixth Street from
Cleveland Avenue to Rochester Avenue. Both the project
sponsor and the Cucamonga County Water District will par-
ticipate in funding the installation of the water main.
Sewer service is available at either Milliken and Sixth
Street or Rochester and Sixth Street with the probable ex-
tension to the east toward Rochester. The cost of this
installation will be paid by the project sponsor.
a
The installation of the water and sewer systems will re-
quire the obtainment of a street might -of -way in Sixth
Street from Cleveland Avenue to Rochester Avenue. Without
this right -of -way, easements will have to be obtained to
allow the line installations.
The quality of wastewater that will be discharged from the
site is unknown at this time. The only Pluess Staufer
plant with a similar
wastewater stream has just begun ini-
tial operation in Vermont. Wastewater samples from this
plant will be furnished to the Cucamonga County Water
District as soon as operations are adequately stabilized
for samples to be representative. General agreement has
been
reached in verbal discussions with Lloyd Michael that
the Cucamonga County Water District will accept the Pluess
Staufer wastewater stream based on their assurance that
additional on -site treatment facilities will be added, if
needed, to meet the standards of the Cucamonga County
Water District. However, if by some unforeseen develop-
ment the discharged wastewater is not acceptable to the
Cucamonga County Water District, there is the option of
discharging to the Chino Basin Municipal Water District's
Non - Reclaimable
Line, located in Eighth Street.

The Southern California Edison Company will provide and
install electrical distribution facilities to serve the
proposed project in accordance with the applicable tariff
schedules and subject to receipt of such charges and per -
mits or other authorizations as may be required for such
installation. Any relocation or rearrangement of Edison
facilities will be at the project sponsor's expense.
The Southern California Gas Company has facilities in the
project area at the intersection of Eighth Street and
Rochester Avenue. Gas service could be provided without
any significant impact on the environment. The service
would be in accordance with the Company's policies and ex-
tension rules on file with the California Public Utilities
Commission at the time contractual arrangements are made.

The Chino Basin Municipal Water District has expressed
concern about the type of settling ponds to be used (lined
or percolating ponds) and tiro peak amount and complete
analysis of effluent to be discharged. The project spon-
nor has indicated the settling pond for solids will be
lined. It is anticipated that all wastes can be accorted
that the C�rino

Basin lion- Raclaimable line will not be utilized. An
analysis of wastewater effluent will be provided to both
districts when available.
The settling ppends will require a waste discharge permit
from the California Regional Water quality Control Board -
Santa Ana Region. This permit will ensure that the lined
settling ponds are imperreable and that there will riot be
overflow. The Water quality Control Board is not con-
cerned with the water quality of the wastewater as it is
being discharged to a sewering agency.
The Chino Basin Municipal Water District has asked if the

will also be used for miscellaneous water requirements
such as area wash downs, etc. A small ovbrflow from the
ponds will be necessary, however, and this is the waste-
water stream that is planned to bet routed to the Cucamonga
County Water District sewer.

AIR QUALITY
Environmental Setting
The climate in the West Valley area of San 9ernardino
County is classified as Mediterranean, characterized by
mild winters and hot, dry summers. Annual precipitation
averages about 20 inches, the majority of which occurs
from December through March.
Air quality in the Rancho Cucamonga area, as well as in
the South Coast Air Basin in general, is affected by cer-
tain meteorological conditions through most of the year.
Prevailing westerly winds as shown in Figure 12, bring in
polluted air from Los Angeles and Orange Counties, com-
p
pounded by the stable air conditions and inversion layer
I@/
common to the area. The in -flow of polluted air and the
concentrating effects of tho local mountains results in
one of the worst ozone problems in the South Coast Air
Basin. Santa Ana wind conditions occur between November
<'
and April with intermittent high winds and resulting dust
P
storms.
Rancho Cucamonga is located in the San Bernardino County
Area, South Coast Air Quality Management District. 1976
air quality information for Upland, four miles to the west
and Fontana less than four miles to the oast are presented
In Tables 1, 2, 3 and 4. The air quality data indicates
that the region around the project site is heavily im-
pacted by photochemical oxidants (ozone), non - mothane
hydrocarbons
and suspended particulates. Air pollutants
encountered in this area are both natural and man -made in
origin. Natural sources are organic gasses (hydrocarbons)
from underground sources, dust and other particulates from
wind activity and photochemical aerosols and chemicals
from reactions between natu -ally- produced ozone and hydro-
;.,
carbons. Man -made sources are primarily automobile re-
lated, generated in the Los Angeles and Orange County
areas. Additionally, this area is impacted by oxidant and
particu'late pollution produced at the Kaiser Steel Facil-
ity and Southern California Edison - Etiwanda complex.
These industrial sources have a localized effect on oxi-
dant, sulfur oxides, nitrogen oxides and particulates.
Other sources include various industrial
sources, agri-
cultural activity, construction and commercial sources.
The recorded air quality data indicates high levels of
pollutants encountered at both monitoring stations and the
number of days in which the state and federal standards
were exceeded.

Notes:
°National Air quality Standards as presented in the Coda
of Federal Regulations, 40, Protection of Environment,
Part 50 Sec. 50.4 to SUM, July 1, 19749 U.S. Govern-
ment Printing OfficU, Washington, DC, 1974.
Primary Standard: Necessary to protect the public health
(Sec. 50.2).
Secondary Standard, -Necessary to protect the' pub is wal-
fare and the environment from known or anticipated adverse
effects of a pollutant (Sec. 50.2).
bNot to be exceoded more than once per year.
°Annual arithmetic mean.
dAnnual geometric mean.
°Photochemical oxidants, corrected for NO2 and S02 interference.
fStandard has two short - period requirements, both of which must
be met.
gTot•al hydrocarbons rcrrected for methane; i.e., total hydro-
carbons minus methane.

Project Impact
Implementation of the proposed project will impact air
quality in throe ways. First, thorn will be an inera-
mental increase in motor vehicle related pollutants from
the vehicles of approximately 70 day -shift and 40 remain -
ing shift employees and from the small amount of truck
trips generated. There will be a few utility vehicles on-
site, most of them intermittent use or electric powered.
Raw materials and a portion of the finished products will
be transported by rail car.
An estimate of the motur vehicle related emissions is con-
tained in Table 5, including a comparison of these pol-
lutants to the area -wide emissions inventory. The amounts
of pollutants resulting from mobile sources will be mini-
mal and the impact is considered small. This impact will
be expected to d3erease as automobile emissions improve.
TABLE 5
Estimate of Pollutants from Employee Vehicles
Total number of employees: 110 (ultimate daily)
Assumed average trip length(a): 7 miles one -way
Total vehicle miles travelled ■ 1,540 milos /day
Applying the above total to the AP -42 methodology, the
following emission rates were calculated for an average
vehicle in the South Coast Air Basin(b).
At project onset (1980)
CO 16.8 g /mi x 1540 miles ■ 56.9 ib /day
NOx 1.9 g /mi x 1540 miles - 6.4 lb /day
SO 0.1 g /mi x 1540 miles ■ 0.3 lb /day
TSP 0.3 g /mi x 1540 miles ■ 1.0 lb /day
HCO 1.1 g /mi x 1540 miles ■ 3.7 lb /day

particulates created by wind emission of the site area.
The principle potential source of fugitive dust is the rock
storage pile. Since rock as received will have been
screened and washed prior to shipping to Rancho Cucamonga,
the only potential particulates for becoming airborne will
be those created during shipment and stacking. Based on
factors in AP -42, the estimated fugitive dust emissions

Dust emissions, due to wind erosion, are estimated to be
about 0.46 lb /hour from AP -42 factors. Assuming windy con-
ditions 24 hours a day for three months of the year, the
average annual dust emissions from storage pile wind ero-
sion is 2.8 lb /day average.
Fugitive dust from process buildings is expected to be neg-
ligible due to extensive use of dust collectors and dust
supression systems in all process steps.

tion of the suspended particulates found in this area.
Air impacts
quality from this project are small and of min -
final impact for all pollutants. Particulates are the nost
significant type of emission due to the relatively high
level (although still well below the 250 lb /day maximum)
and due to the high ambient levels presently being exper1-
enced iii this area. Oxides of nitrogen, the next largest
emission quantity, still represents only a third of a per-
cent increase over the area of the Pomona- Walnut valley
airshed.
The remaining pollutants comprise less than six tenths of
a percent increase over t:ie present emissions inventory
for the area for mobile and stationary sources combined.
The overall air uality impact is considered incremental
with those qualifiqcations previously mentioned.
The third type of emission source is that of off -site in-
direct stationary sources. These include air pollutants
created in supplying the proposed project with energy dur-
ing operation. The primary source of these emissions is
from fuel -fired generations of electricity. Estimates of
these pollutants are as follows:

Mitigation Measures
Because
of the serious existing air pollution problem in
the Rancho Cucamonga area, careful employment of mitiga-
tion measures is a necessity. The project, as proposed,
employs a range of mitigation measures which strongly re-
duce the amounts of pollutants released into the air.
They are as follows:
1. Rock
as received is pre - washod and screened to olimi-
nate particles of 310" size and smaller. This strong-
ly limits particulate emissions occurring in transit
to the project site and greatly lessens the potential
for fugitive dust from receiving, unloading and stock-
piling operations.
2. Wat dust supression equipment is employed in the rock
unloading area, roil car area and on the reclaim sys-
tem for the on-site stockpiles leading to the crusher
house.
3. All crushing and dust creating processes are enclosed
in buildings to greatly enhance dust control and fa-
cilitate collection of airborne and process particu-
lates.
4. Dust collection!; and dust bag filtration will be em-
ployed in all'processas from the primary crushing step
through the final steps of warehousing and loading at
finished- hagged products. A combination of fan col-
lectors, pulse -jet type baghouses and electrostatic
precipitators will be used.
S. On -site roads, especially those with truck traffic,
will be paved to lessen dust created from vehicular
activity.
6. Truck on -site haul distances are,limited to short dis-
tances and on -site circulation is in a loop which al-
lows efficient traffic patterns.
Other mitigation measures which could be employed to re-
duce emissions include:
I. Decreasing pollutants produced in natural gas combus-
tion procession (140x, SOx, CO, Particulates) by:
Down
a. - sizing the processes and plant capacity
b. Additional pollution control devices
c. Employing an alternative process design which uses
fewer combustion processes.

2.
Use of wind fences to roduco ground level air turbu-

3.
Employing truck speed limits on -site to reduce dust by
decreasing air turbulance near ground levels.
4.
Dust control maintenance and treatment of paved and
unpaved areas which contribute to dust.
S.
Landscaping and ground cover of all graded or cleared
areas to reduce airborne dust.
G.
Offering employee incentives for carpooling by such
7.
methods as preferential parking.
Providing bus
a shclter on Arrow Highway at Rochester
Avenue and provide bus scheduling information to em-
ployees.

Encouraging private park and ride services.
9.
Decreasing electrical demand by modification of energy
consuming processes.
10.
Control of dust from grading and construction by com-
plying with regulations of the Agriculture Department
which include:
a. Establishing ground cover by November 1st to pro-
tect against Santa Ana wind conditions.
b. Use of oil sprays and /or watering.

AESTHETICS
rnv'iromnental Settl'ng
The project site is curronLly under cultivation with grape
vines. Surrounding properties are either in agricultural
use or dovoloyad as heavy industrial as shown on the
aerial photo, Figure 4.
Project Impact
The proposed project, involves the construction of a cal-
cium carbonate crushing, grinding and processing plant.
Placement of plant facilities is shown on Figure , the
Si to Plot Plan. Implementation of the project will
involve the removal of all grape vines with the exception
of those on the northern third of the property which will
remain in open space.
Aesthetically, tiie majority of facility operations are
enclosed in buildings and will not be viewed by the pub-
lic- With the closure of Eighth Street, the only oublic
view will be from the proposed Sixth Street. The primary
view from this location will be the office building, pro-
cessing buildings and landscaping. The office parking
area will be separated from the processing facilities by
fencing which completely surrounds the processing area.
Building elevations are shown on Figures 7 and 8. Due to
the industrial nature of these buildings, the elevations
appear quite plain.
The proposed project is located in an industrial area and
will not aesthetically impart any residential areas.
Mitigation Measures
The proposed project should provide landscaped areas
adjacent to the proposed Sixth Street, the office building
and the parking areas.
4
4�
Landscaping which will not interfere with plant operation
should be placed adjacent to processing buildings to pro-
vide visual relief.
Landscaping should comply with landscape standards estab-
lished by the City.
All landscaping should be provided with a permanent under-
ground watering system and should be maintained free of
weeds, debris and litter. All landscaping should be

IV. ADVERSE. ENVIRONidENTAL EFFECTS
The conversion of undove lope d land to industrial use will
result in certain unavoidable adverse impacts which cannot
be completely mitigated though some of the impacts can be
�I••.
reduced to an insignificant degree.
44
The proposed project will alter planned circulation in the
area and result in an incremental increase in traffic.
This impact is lessened by circulation changes to the
Circulation Element of the General Plan which have boon
recommended by the Planning Commission as discussed in
Section III. Circulation.
The proposed project will result in increased runoff due
to the introduction of impergicable surfacus. This impact
will be lessened upon enforcement of City Ordinance 24.
The proposed project will utilize pubic services and
facilities. The sort ices and facilities have indicated
they do not anticipate any service Froblems.
Loss of open space will be lessened by the retention of
the northern portion of the site in grape vines and the
provision of landscaping.
Decreased air quality is lessened by implementation of air
r
pollution control measures in plat design.
The project impacts can primarily be reduced to an insig-
nificant degree. The impacts remaining are those impacts
which occur with all development of this nature. This is
why the project is proposed in spite of these impacts.

avoided. It would also retain the site in a non - productive
state.
ALTERNATIVE INDUSTRIAL PROJECT'
The project site is within the industrial area of the City
of Rancho Cucamonga. Therefore, if the proposed project is
not implemented, another industrial project by another pro-
ject sponsor could be proposed for the site. This alter-
native industrial project would have similar impacts to the
proposed project though possibly to differing degrees.

A smaller fac111t,y with less capacity could also be con-
structed on the project site. The only impact which would
be lessened would be air quality though to an undetermined
amount. This 'alternative was rejected by the project
sponsor because the economic viability of the project is
directly in proportion to plant size.
ALTERNATIVE LOCATION
The proposed facility could be located on another site in
the industrial area or outside of the City's boundaries.
Several sites were investigated by the project sponsor.
While other sites were adequate, the project site was
chosen because it offered the best combination of railroad
access and public services and facilities.
An alternative location would not alleviate project impacts
but just relocate them to another site.

Vi. 011014TH INDUCING IMPACT
46
Almost all urban growth and concomitantly the demand for
goods and services, is
predicated on employment expansion.
An increase in jobs means manpower expansiono which in turn
adds more people to the population, greater buying power
due to payroll enlargement and higher levels
of consumption
culminating in the rising demand for -now housing, retail
goods, services and all other activities nocessary to sup-
port dwa111ngs. The
process of growth is highly dependent
on the introduction into an economy of basic industries
which produce goods or services that are exported for the
most part beyond the boundaries of the local region. This
Is the only way any continuing amount of now money can be
Put into circulation giving life to
expanded economic
activity. If the only money in circulation were that pro-
duced from sales to persons living within the local economy
instead of any flows from without, the supply would never
increase and there would be no potential fcr expanding the
existing level of economic acttvity.
The proposed industrial facility will employ approximately
100
persons. Assuming an average household size of 2.43
persons *, tills would amount to a population gain of approx-
imately 243, if all employeas were
new and moved to the
City. These new employees /residents will require housing
in the City or surrounding areas.
New development in the industrial area of the City may
stimulate other industrial development due to the expansion
of public facilities and services to the area.

III, DETEtuIiNATION
On the basic of thin initinl wsluntion:
I' rind the proposed project COULD NOT have a nigcifiennt affect
on the anvironmunt, and a NEOA:1VK DECLARATION will be prepared.
I find that although the proposed project could have a significant
affect on the onviroument, there will not be n significant affect
In thin Cana becauna the mitigation manures described on an
attaciiod shoat have boon nddad to the project, A NEGATIVE
DECLAhATION WILL BE PREPARED.
I find the proposed project MAY liavu a significant effaet on the
onvirnmant, and an ENVIRONMENT IMPACT REPORT is required.

extraction of m1nornl resources will be required. ,A dos -
cription and inalyole
of this process in necannory to dater -
mine any significant effects an a ruuult
of extraction.
2. 11Ydrolo$y: This project and ita ultimata improvements will
change absorption drainage
rates, patterns and increase
the amount of surface
water runoff, In addition, this
site may be subject to flooding. Drainage studios
are
needed to determine the extent of possible flooding or
dralange
problems and the mitigation measure" accessory to
solve those problems.
3. Air puaLit - 'Ellis project will most likely utilize heavy
equipment and machinery, Mnissions Zrom either stationary

to the local air quality. In addition, stock piling of raw
material could cause deterioration
of the ambient air quality

Pleuss- Stnufer, a manufacturing firm, ties requested that ilia plannad extension of 701
Street through Its property be deleted. Pleoss- Stnufer also has requested that Eighth
Street be closed :djolning Its site. This memorandum analyzes the impacts of these
proposals.
31to and Plant Description
1'leuM- Stnufer proposes to construct a plant on an 80 acre parcal shown on Exhibit 1.
The plant will front on Gth Street (riot presently constructed), with both employee
parking and truck access provided from a single entrance on Gth Street. 'rite entrance
will be approximately in the middle of the site.
The plant will pulver lzu rock which will arrive vin the Santa Fe rail lino adjoining 8th
Street. 'rhe finished product will be transported by truck. Hail movements will consist
of two 15 -2p car trains cacti day. Truck movements will include 20 -25 trucks at the
plant per day. The plant is a scvei; day /wock, 24- hour /day operation. Fewer than 100
employees via be bused at the plant. Approximately 00 will be on the day shift, inclu-
ding 20 -25 office /manngerial workers. Skclutor� crews will man tiro plant at night.
'Grip Generation In Area "C"
Rancho Cucamongn's industrial area has been divided Into three segments for Planning
purposes. Area A is west of Haven Avenue; D extends from Haven to the Devore Free-
way and Area C is east of the freeway. Trip ;enerr'ton in Industtial Area C iz critical in
determining whethe- a through east -west street Is needed between Arrow Route and 4th
Street.
Area C includes approximately 1,500 acres. Projections of future employment densities
range from a lots of four employees /acre to n high of 12 employees /acre or 6,0100 to
18,000 employees at full development. The lower end of this range is more likely than
the higher end.

For land use typo 140 (mnnufaoturina;), the 11T Trip Gcneration Mnnu01 spuclflas a mlail-
mum of 1.30 trips /employee /day (TED), with an avorni {c of 2.17 TEN). A maximum rato
of 5.4 Tub was used In a study of the Irvine ]nj,istrinl Parl(. Using; a pent( hour fnotor of
30 percent, genic hour trip generation Is eomliuted all follows:
Daily'Trlp -L'nds In Area
Peale !lour Trip Productions
Trip l7anerntion Assumption
Low Median High
8,340 201040 07,200
1,334 49155 150552
Tho prlmory users of the existing 7th Street Undercrossing of the Dovoro Freowny would
tie work(eas Rv:ng In the western portion of Rancho Cucamonga. A trip - length distri-
bution curve (sae pogo 3) which ussumes an average trip length of six miles, serves as tlae
basis for •a preliminary estimate that between 5 and 12 percent of those working in Area
C will live In west Rancho Cucamonga. These workers will find three surface traffic-
ways -- FoothW, Base Line, or tlae lath /7th continuation — faster than using either the
San Bernardino Freeway or ttae r-oposed Foothill brttoway.
Using the snedlan trip generation assumption, 1,300 to 3,100 trips would he added to the
ADT of these through east -west trafflewcys (200 to 500 trips (luring the pent( hour). At
the maximum loud point (Haven Avenue), the San Bernardino County Public works
Department 1070 study projected a 1005 ADT of 27,000 on Foothill and 24,000 on Base
Lino. An April, 1070, study by Weston Pringl,a and Associates that nssume3 major
shopping center development In two quadrants of the Haven- Footnill Intarsection pro-
jects ADT of nearly 400000 on Foothill cast of llaven.
Without a through route on 8th or 7th Streets, the additional 1,300 -31100 trips would be
distributed bet,vicen FoothW and Base Line. While the through route Is not absolutely
necessary to serve Area C, deletion would cause servico levels on enst -west routes to
decline unless a lane In each direction could be added to Foothill or Buse Line.
Trip Generation in Area "B ".
'rhe industrial area between Haven and tiro Devorc Freeway Includns about 2,300 acres.
Assuming 600 acres Is most easily accesslWo from the , 9rimotcr streets (Ilnven, Foothill,
Rochester, and 4th), 1,500 acres would ha served mainly by Milliken Avenue and 6th, 7th
or 8th. Because tills acreage is the same as In Area C, the same density assumptions
prodace the same numGer of trip ends as In the table above — 8,340 to 97,.'00. Assumgn-
an equal division of this traffic between Milliken and tlae cast -west route volume could
approach 30,000 ADT o'.: `ho cast -west route, Including the 1,300 -3,100 trips destined for
area C. It is more likely that volumes will be less than 25,000. 'fhe traffic model now
being prepared will narrow the range of uncertainty by more carefully documented
projections of future employment densities and by more accurate trip assignment to
specific streets.
In order to handle a volume approaching or exceeding 25,000 AD'r, the enst -west street
will need to be continuous between Haven and fiochestcr even [f no through trips were
projected. Attempts to serve Area B with cul -de -sacs or loops would overload the peri-
meter thoroughfares by forcing knta -zonal trips to use them. Any unforseen concentra-
tions of empi -jymcnt that substantially exceeds the density assumption would throw such
a system out of balance because adjustments In routes to increase capacity would not be
possible.

AnalysIH ,
rive questions must be answered bafore the City can rospo:Id to plouss- Staufor's
requests.
1. Can 8th Street be closed without causing congestion or disturbing network
continuity?
There are no apparent reasons why 8th Streat can't be closed, and,, in fact, there nrpears
to be a general consensus that It should bn, although needs of owners fronting on 8th
must be studied further before the segments to be closed can be determined and the
timing of'tha closures recommended. But, if dill Is closed end 0th and 7th Streets do not
run through, east -avast continuity will be Impaired, leaving no through streets between
4th and Arrow Route (about 8,000 fact).
0th Strout Is Immediately adjacent to the Santa re mainline track. The street is two
lanes wide and generally Is In poor condition. Decatise It is three to five fact boow the
grade of the ra8road truck, there are humps at every intersection with cross streets. At
several of these, eight distance is severely restricted for vchleies on 0th Street and for
northbound ve41cle8 on the cross streets attempting to turn left onto 8th Street.
CSeveral flood control channel crossings are at- grndr. Spur tracks cross 8th Street to
serve industries to the south. in the future, more crossings will be needed, Each must be
protected by flashing lights and possibly by gates. 'rho cost could rnn;e up to $100,000 at
each location.
Bringing 8th Street up to standard would require raising its grade three to five feet,
1 signalizing all Intersections with major cross streets, (Including rnilroud pre -empt at
$10,000 to $20,000 cost penalty), and building several bridges over flood control
channels. Such a costly project is not wntranted because equivalent, if not better, east-
, west traffic service can be provided by 8th or 7th Street. Continuity nt the east end Is
not an Issue, since 0th Street does not cross the Devore Freeway. Continuity at the west
end can easily be provided by a connector road parallel to Cucamonga Wash, between
or 7th Street and 8th Street. (See Exhibit 4) 0th
2. Can 7th Street be deleted without causing congestion or distuubing network
continuity?
With 8th Street abandoned, 7th Street would be the logical alternative for a through
street,
half way between t4th Street dand rArrow Route. DA precise plan for d 71:11 Street betwleen
Vineyard Avenue and Etiwanda Avenue was prepared in 1972 end has been oJopted by the
Milliken, If not to tile DevorcdrreewayalEven if ite ere not a through street, 7th would
function as a collector street in plcca of 8th Street.
-4-
a
0. li7w should 0th Strcct be developed In the ovent that all or portlons of both 7th and
8th Stroota ate abnndoned?
If both 7th and,8th Streets nro :locod, Gth Street becomes the only potential through
Oust -west neterlal connection, 0th Street: presently terminates at Pot n. If 7th (s not
built, 0th should extend at least to Rochester. Three udlernutivea for a through con-
nection warrant consideratian
(a) A "T" intersection with Rochester requiring a left and right turn to jg up to the
7th Streit alignment and the Davore Freeway Undercrossin ,
additional capacity ()a llochastur to handle the offset Intersections, Rooh'eaprrovWo
should be widened to 04 feat curb -to -curb between Gth and 7th Strocts, with.transl-
ilon areas at either and. Exhibit 0 shows a possible lane arrangement.
(b) Bulld a "West Rochester" parnii.el to ROuhestcr between oth and 7th Strocts, but
nbout 88o feet to the west. Rochester would not need to be 'widened,
(c) Build a curved road connecting Gth Street to the 7th Street undercrossing, ollml-
natinte, turning movements and allowing 40 mph traffic flow. (Exhibit 1) 'Ch ha
ia s
tiro disadvantego of cutting parcels Into odd - shaped sizes, but could be worked out
with little disruption If property owners are willing to consider trades.
4. What provisions are neoded for truck access to the regional freeway system?
industrial development in the area will generate truck trips mainly to the San Bernardino
Freeway, Truck access to the Plcuss- Staufer site can be via Rochester from the clover-
leaf at 4th Street and Devore Freeway, but trucks destined to the San Bernardino or
Pomona probably will not use the Devore Freeway. When Milliker, Avenuo is
extended north to 0th Strant, most truck trips may divert to Milliken to tench the Sari
Bernardino Frcoway because the uistance Is shorter for the predominant westbound
destinations.
5- Shiuld cast -west continuity Into Ontario be provided via Gth or 8th Street?
Last -west continuity Into Ontario can be provided e't_her to Gth Street or to 8th Street.
tharn Street Is 6th Street. One solut
ion would be to buldaidiagonal roadway along ts,a nannower
east bank
Of Cucamonga Wash between 6th and 8th Streets. Exhibit 4 shows that a 40 mph align-
ment is achievable. Gth Street could be turned to intersect the connector road at 90 1
degrees or the connector road could Inters ^ct 6th Street at 90 degrees. The choice of
designs,wOUld depend on which street would carry more traffic la Ontario — 8th or Gth.
The decision should be made jointly by the !•:vo cities.
built to Secondary Thorou;7th Street should be extended westerly to connect to th -, new connector, which should be
hfare standards.
If the connection is not bunt, Hellman would carry the through traffic between Gth and
8th Streets. This would exacerbate the already dangerous sight distance problem at 8th
place, Gth Street could especially
e abandonedfe stror the the connector road In Hellman /8th Street
intersection need not be rebuilt. i

The feasibility of constructing the oonnoator will dopend, In pru't, on the pluns of
affected landowners who can dovolop whon Cucamonga wash improvements arc eorn-
plcta. A doaislen need not be made before, the question of deletlna 7t1: Strout coat a[
linvan Is resolved.
Summary of Concluslorw
— 7th Street noad not be continuous through the Picuss- Staufer site.
— 0th Street can be abandoned.
— An additlor +al cast -west roadway Is necessary between Arrow Route and 4th Street,
— 0th Street Is the most logival cast -west connector. It should be connected to 0th
Stroat at the west and and to 7th Strout at Rochester at the onst end. Until the
traffic model for tho Industrial Area Specific Plan Is In operation and available for
more precise analysis, any development approvals should provide for dediention of a
110 foot right -of -way allowing six movinV limos (Includ!ng 10 foot lanes adjoining
tho curbs) and a continuous turn lane. if the model Indicates flint no more than four
lanes are likely to on needed, the right -of -way could be narrowed to 92 feat.
Additlonol right -of -way should be provided at intersections with major north -south
streets to allow for future double turn lanes that may be needed,
-- Three Mornative connentor alignments aro possible nt the east end of 0th Street.
A direct uonnection (Exhibit 1) or a "west Rochester" are preferable to a widened
Rochester ONlilbits 2 and 0) for access, traffic operations, capacity, and safety
reasons.

Enclosed herein are two prints of the 1969 flood overflow map wil:h tite industrial
area of the City of Rancho Cucamonga platted thereon. It is understood our work
(L. D. KING) in Phase I of the specific plan project is primarily cursory !n nature.
However, there is inrormation included herein that may bt of liilue at this time in
your initial planning and traffic studies. Additionally, we will review those
existing storm drain plans and drainage problems in the industrial z "2a to the
extent our budget constraints will allow, during Phase I. We will also review the
Planning and traffic plans for drainage and flood problems as necessary.
As I Indicated earlier, the deletion or alignment of streets in an east -west direc-
tion (6th, 7th and 8th Streets) will not materially affect drainage as long as
adequate structures are provided to pass draintlge through the area in a north -
south direction. The Pleuss - Staufer parcel doer, not have a major flood problem,
and the deletion of 6th, 7th or 8th Street would not have any significant affect
on drainage Because of the north -south flow of draip ?ge and until such time as
a storm drain system for the area is provided, the not•th -south street system is
important and necessary for conducting both onsite and offsite drainage flows
southerly. Enclosed i5 copy of a report on the Pleuss- Staufer parc,.;l for your
information.
The 1969 flood overflow limits indicate the major flood problems in �:he area. Al-
though the 1969 flood was not a 100 -year event in the Dcer -Day Creek area, it has
been used as a major focal point for flood hazard reporting and protection.
In the "A" and "B" areas, the major flood problems are due to overflow from Cuca-
monga Creek along the westerly part of the City and from Deer Creek through the
middle part ut the City. These two major flood' sources will be eliminated by the
completion of the Cucamonga Creek Improvement Project, presently under construction
by the U. S. Corps of Engineers. There dre other flood problems to areas "A" and
"B", but these two are the major problems.

The westerly part of area "A" is subject to overflow from Cucamonga Creek. This
area was subjected to overflow during the 1938 and 1969 floods, particularly the
area between Cucamonga Creek and Hellman Avenue. During the 1969 floods, several
of the existing industrial developments along Arrow Route and Hellman Avenue were
damaged. After the flood, several businesses constructed low.block walls to pro-
tect the buildings by diverting future flews around the building sites. Subsequent
to the 1969 flood, several new industrial complexes have used a combination of low
block walls, parking areas, and site grading to mitigate potential flood hazards.
Although those mothods will not provide comp at protection, they do assist in re-
ducing flood problems due to overflow.
The Cucamonga Channel is due to be completed up to Foothill Bouelvard by March of
1980. The reach of the Cucamonga Channel from the Ontario Airport to .Foothill
Bouelvard, along with the Cucamonga Debris Basin, is due to be advertised this
1
month. The reach from Foothill Boulevard to the mouth of the canyon is scheduled
for advertisement in March of 11710 with completion in March of 1981. The major
breakout point on Cucamonga Crcak is just north of Foothill Boulevard. When this
reach of Cucamonga Creek is completed, it will remove practically all of the major
flood problems from area "A" due to canyon flows. There will still be a major
problem along Hellman Avenue until the Demens Channel project is complete, How•
ever, flood flows along Hellman Avenue have been mitigated to a reasonable degree
in the past by the construction of a block wall along Hellman Avenue. The Demens
Channel and Debris Basin is scheduled for completion in March of 1981.
As mentioned above, Deer Creek overflow affects the westerly portion of area "B"
primarily, and the entire area (area "B ") to some extent. Please refer to the over-
flow map and to the report "Drainage Study and Design Concepts, R. C. LAND COMPAiiY ".
The Deer Creek Channel and Debris Basin is scheduled for completion by January,
a
1982. The completion of the Deer Creek Channel will remove the major flood problem
due to canyon flows from area "B" However, there will still, be a potential flood
problem to the area from Day Creek to the east. The Day Creek problem can be
mitigated to a large degree by the improvement of the Day -Deer Creek Separation
Levee. Please refer to the above referenced report, "Drainage Study and Design
Concepts, R. C. LAND COMPANY ", for details. In the interim period, reasonable
flood protection can be provided along the area adjacent to Milliken Avenue with
the utilization of low block walls, landscaped berms, site grading, or a combina-
tion of methods.
The above discussion has been primarily on major flood problems and not storm
drain problems. Even with the completion of the Federal f eject, there will still
be major, local drainage problems associated with development runoff and street
drainage. This type of drainage problem can only be mitigated with the develop -
ment of an adequate storm drain system in conjunction with drainage flows carried
in streets. As you are aware, the existing Comprehensive Storm Drain Plan was
�`
completed in 1969 and is to a degree outdated and should be revised.
