SUBJECT:
Case No. CUP-140, County Refuse Shredder
Applicant: County of San Diego
STATEMEWOF THE MATTER
The subject property is situated on the east side of El Camino Real
north of Palomar Airport Road. The site is a 21 acre portion of a
230 acre lot (See Case No. ZC-197 for rezoning).
The Planning Commission heard CUP-140 after approving the rezoning
on the subject site from "O-S"to "M". However, the Planning Commission
denied the CUP for reasons outlined in attached Planning Commission
resolution No. 1405.
Prior to taking action the Planning Commission reviewed the request
in detail and developed conditions of approval if the CUP is appealed
to City Council. (Section 21.50.130 requires that contrary decisions
of the City Council on appeals must be referred back to the Planning
Commission for further report.) This report is attached, dated September
30, 1977 and contains all of the conditions the Planning Commission feels
are necessary for proper operation of the project.

MEMORANDUM
DATE: SEPTEMBER 30, 1977
TO: CITY COUNCIL
FROM: PLANNING COMMISSION
RE: APPEAL CUP-140, COUNTY OF SAN DIEGO
CUP-140 is the county's request for a Refuse Shredder and Transfer
Station at property situated on the east side of El Camino Real,
north of Palomar Airport Road. The Shredder is to be situated on
a 21 acre portion of the 58 acre site that the City Council is
presently processing a request for a change of zone to M (ZC-197).
The Planning Commission heard both ZC-197 and CUP-140. The Plan-
ning Commission recommended approval of ZC-197 but could not reach
a majority vote to approve the Conditional Use Permit. To circum-
vent needless continuance in an attempt to get a majority vote,
two members of the Planning Commission changed their vote to denial
so that the application could be appealed to the City Council.
Prior to making this vote for denial, the Planning Commission ex-
tensively reviewed the CUP request. Every condition was individually
reviewed, many were modified and some conditions added. Although
the action was to deny the CUP, the Planning Commission concurred
that the conditions that they set forth were applicable. To eliminate
the need for a return to the Planning Commission for further report
if the City Council action differs from the Planning Commission
recommendation, the Planning Commission is forwarding to the City
Council the attached conditions. The Planning Commission therefore
considered this report as their final action.
Recommendation
If the City Council wishes to approve CUP-140 on appeal, the Planning
Commission recommends that the conditions as attached, and findings
as contained in the staff report be made part of the approving
City Council Resolution and that no further report be requested
from the Planning Commission.
Attachments
Conditions of Approval, as prepared by Planning Commission 9/28/77.

SECTION II: BACKGROUND
t
Location and Description of Property:
The 21 acre site for the shredder is part of a 230 acre lot that is
partially zoned 0-S (172 acres to the south) and 58 acres being rezoned
to M (ZC-197). The property is located on the northeast side of El
Camino Real between Sunny Creek Road and Palomar Airport Road. The
majority of the 58 acre M zoned portion was previously cultivated,
with the remainder of the site covered with the inland sage scrub
community. A detailed description of the site is contained in the
project EIR.
The Conditional Use Permit applies only to the southerly 21 acres.
The remaining 37 acres of M zone has not been specified for a particular
use, although the possibility of constructing a municipal corporation
yard on that site has been discussed. Any public use built on that
site in the future would be subject to a Conditional Use Permit.
PROJECT DESCRIPTION .
The project involves the construction and operation of a solid waste
shredder, resource recovery and transfer station on a County-owned
site. The shredded waste can be more easily disposed at sanitary
landfill sites without using excessive cover material.
Initially the project will receive and process 166,000 tons of solid
waste per year, increasing to 220,000 tons by 1982. The facility
will shred the waste, separate ferrous (iron-derived) metals for
resale, and compact the waste into large tractor trailers for
efficient transfer to the San Marcos Landfil1. All trash would be
transferred to the landfill on the same day which it arrives, thus
reducing the potential for odor.
The facility will consist of approximately three buildings (1. 6000
square feet and 35 feet high, 2. 2000 square feet and 24 feet high,
3. 3000 square feet and 24 feet high), conveyor belts, shredder
machines, magnetic separators, trailer loaders, pavement, security
fencing, utilities, parking and appurtenant items for complete
operation. All processing operations will be done in enclosed
buildings to reduce noise and odor impacts. Approximately 11,000
square feet of space may be required. Some buildings may be as high
as 35 feet.

Past History and Related Cases:
The Planning Commission approved a General Plan Amendment for the
project on August 24, 1977 and was approved by the City Council on
September 21, 1977. A companion item to this request for Conditional
Use Permit is Zone Change 197 to change from 0-S to M.
Environmental Impact Information:
The County has prepared and certified an EIR for the project. The
County is the "Lead Agency" for the siredder project (i.e., ths agency
responsible for carrying out the project). The City is a "Responsible
Agency" under State law, and must therefore consider the information
contained within the Lead Agency's EIR prior to taking any action on
the project. All mitigation measures which are Carlsbad's responsibility
have been recommended as conditions of approval to the Conditional Use
Permit for the shredder.
General Plan Information:

Commission is considering the request that

and transfer station and a possible municipal
ocation for City police, water, utilities and
-6-
The property is within the Special Treatment designation for the
Palomar Airport influence area. This special treatment designation
indicates that, in addition to the underlying land use designation,
special consideration should be given to the property due to the noise
and safety impacts of Palomar Airport. The proposed shredder is
compatible with the airport influence. According to the County, CPO
(acting as the Airport Land Use Commission) has reviewed the project
and has found that it conforms to the Palomar Airport Land Use Plan.
The Open Space and Conservation Element of the General Plan shows
the canyon east of the subject site as a part of the City-wide open
space linkage. This area is proposed to remain in open space.
PUBLIC FACILITIES:
This application was accepted because the sewer moratorium ordinance
7048 provides for the acceptance of government facilities. However,
there are no assurances that public sewer facilities will be available
to serve any future uses proposed for the site. However, water and
other utilities are available to the site.
The County ordinarily proposed that sewage generated by the use (on
site restrooms only) was to be accommodated by a septic tank system.
Percolation tests conducted by the County have shown that a septic
system is not feasible, however.
The County has presented the alternative of utilizing: 1) chemical
toilets and a sump system for the washdown of equipment and recycling
of water; 2) the cleaning of machinery by seepers and vacuum devices
rather than by a water wash-down method, or 3) other such methods,
such as evapotranspiration, that will avoid Discharge of waste water.
MAJOR PLANNING CONSIDERATIONS:
Will the shredder cause excessive noise, odor, traffic or aesthetic
impacts?
Will the transfer station cause excessive traffic and safety problems?
DISCUSSION
The County has proposed to fund the project with a Federal Economic
Development Act Grant. The contract for design, construction and
operation of the facility is "turn key" (that is, a private contractor
will design, construct and operate the facility to specifications set
by the County.) Consequently there are no building elevations available
at this time. A condition requiring Planning Director review and
approval of building design has been included.
-7-
Staff believes that design parameters set through the conditions of the
CUP and the grading plan provide adequate information to allow the
Commission to approve the facility. Staff's primary concerns are with
the noise, traffic and aesthetic impacts of the project. Mitigation
measures in the EIR (which are also conditions of approval for the CUP)
require that the buildings be constructed with materials which are
aesthetically compatible with the surrounding area and that noise be
limited to 60dB(A) at the operation boundaries. The noise restriction
is within the standards contained in the City's Noise Element. In
addition, the City Engineer has supplied conditions of approval to
ensure that all traffic impacts can be mitigated.
At the City Council hearing on the General -Plan Amendment for this
site (GPA-49), many concerns were voiced on the impacts of this
proposed refuse shredder. The City Council expressed a desire
that where possible these concerns be mitigated through conditions of
the Conditional Use Permit. Following is a synopsis of these concerns:
"Noise be reduced so there be no significant effect on the wildlife
reserve to the west." The condition requiring a maximum of 60dB(A)
at operation limits and enclosure of the shredding operation will meet
this concern.
"The shredded waste has an o'dor - it is localized and cannot be
distinguished 20 yards away." A condition has been include/d that
requires methods to be instituted that prevent odors beyond the
operational boundaries.
"Will there be interference with radio communication?" The applicant
explained that there is no interference with radio communication at a
similar operation in El Cajon, which is also .near an airport. Also
there are conditions requiring method to be instituted to prohibit
electrical and radio interferences to the nearly solar wind antenna
system. This should prevent noise problems at the airport also.
"Beckman Instruments cannot use pesticides to check rodent population.
If the shredder causes an increase in rodents, Beckman may have to
close because of the need for a clean health environment associated
with the Beckman operation." The applicant responded by indicating
that rodents cannot survive on the shredder waste. This has been
tested in previous studies. A condition has been added that requires
a report on the matter and any suggested mitigating method be installed.
"The shredding operation is dusty. There will be dust collecting
equipment on the site as there is in the El Cajon operations." A
condition has been added to insure that this dust reducing equipment
is installed and functions properly.
-8-
"There will be approximately TOO collection trucks and 40 transfer
trucks using the facility a day." Staff believes the road system
with the required participation in signals is satisfactory to handle
this traffic.
"It will take about 4,000 gallons per day of sewer capacity—about
14-15 equivalent dwelling units.". The sewage will have to be
disposed of through on-site methods. Presently the applicant is
proposing an experimental system. The City is very interested in
monitoring this system because if it is workable (and it appears it
will be), the system can then be used for private development. If
however it fails, the project can be hooked to existing lines that
serve Beckman Instruments. The sewer allocation system provides
capacity for government facilities such as this.

ENVIRONMENTAL IMPACT REPORT DISCUSSION
PROJECT: Paloraar Solid Waste Transfer Station, A Public Project, EAD Log #77-7-34*
•' . " / - 'PROJECT DESCRIPTION ; .
The proposed project is to establish a solid waste shredding facility capable
of recovering Ferrous (iron) materials. The shredded waste will be transported
to existing sanitary landfills: either to the Bonsall or San Marcos landfills.
The shredding of waste material will extend the life span of the San Marcos
facility from its present 3 to 5 year life span to an estimated 20 year life
span. The life span extension effect of the operation of the shredder as dis-
cussed in this EIR is not discussed in the EIR for the San Marcos Sanitary
Landfill.
The project site is located northeast of the intersection of Palomar Airport
Road and El Camino Real in the City of Carlsbad: on a County-owned 21 acre
parcel.
•» ••
EXISTING ZONING
• .
The existing zoning is 0-S, Open Space, in the City of Carlsbad, which under
Carlsbad zoning allows agricultural and recreational uses.
MAJOR ISSUES
1. Noise (See the Following Mitigating Measure)
Noise levels estimated to be in the range of 95-100 dB(A) at a dis-
tance of 50-feet from the shredder will be generated by the shredding
operation unless effective noise reduction techniques are employed,
and noise levels at the nearest property line will be in the range
of 83-83 dB(A) and a 60 dB(A) noise level will exist at a distance
of approximately 3,140-feet from the shredding operation. As a result,
without adequate mitigation, the 60 dB(A) noise contour produced by
this project will envelope an area of approximately 690 acres — in
contrast to the 21 acre project site itself. This impact can be miti-
gated.
Mitigating Measure
Construction of the shredder building should utilize materials which
will insure that noise levels produced by project related activities
do not exceed 60 dB(A) in areas outside of the 21 acre project sites
as a result of activities related to this project.
ENCLOSURE A-2
2. Sewage Disposal (No'Mitigating Measure Proposed; See the Following
Applicant proposed project modifications)
* • ,
No sewage facilities will be available in the area during the next
two years as a result of a moratorium by the City of Carlsbad for
this area. - ...
• •>
The proposed project will produce approximately 4,000 gallons of waste
water per day created from approximately 20 employees and periodic
washdown of equipment. Percolation tests indicate that proper sewage
disposal cannot be achieved via a septic tank-leach line system.
The applicant has presented the alternative of utilizing: 1) chemical
toilets and a sump system for the washdown of equipment and recycling
of water; 2) the cleaning of machinery by seepers and vacuum devices
rather than by a water wash-down method, or 3) other such methods, such
as.eyapotranspiration, that will avoid discharge of waste water.
3. Scenic/Visual (See the'Following Mitigating Measure)
The proposed proj-ect will result in a building 36-feet in height which
v/ill visually impact a planned 400-acre development immediately to
the eu.st.
*Mitigating Measure
The building exterior should be of a nature that the building will
blend in with existing color and textures of the area.
4* Archaeology (See the Following Mitigating Measures)
Three archaeological sites are found in or immediately to the project
site. Two Luiseno milling stations were reported in the Archaeological
Survey Report, prepared by the Department of Transportation and a
A third trail camp (SDi-50-92), indicated by Chione sp. shell fragments
littering the rim of an adjacent canyon, was later discovered by the
Environmental Analysis Division. These sites are theorized to have
been marginal elements of a more widespread regional settlement pattern
involving vegetation and animal resources around Agua Hedionda Creek
and its major tributaries. The marine shell species probably were
gathered prehistorically at Agua Hedionda Lagoon and consumed by a
single individual while enroute to some unknown inland destination.
Ecofact residue at these sites could contribute to a better understanding
of dietary habits in specific time periods.

Division. ~~
5. Biology (No Mitigating Measures Proposed)
Implementation of this project will result in the destruction and/or
major reduction of habitat quality of on-site inland sage scrub com-
munity. This vegetation represents the edge of a contiguous belt
of vegetation adjacent to a tributary of Agua. Hedionda Creek and is
utilized extensively by area wildlife.
Three plants considered threatened and/or of limited distribution have
been identified from the property: Adolnhia califomica,
^inerascens, and Thick-leaf Manzanita, Arctostaphyios glandulosa
crassifolia. In addition to the above species, Summer-Holly,
Coma TO st any los diversifolia was found to be common on the property.
This species is a candidate species for the California Native Plant
Society's list of Rare and Endangered Plants of California. Summer-
Holly .occurs on dry slopes at low elevations in chaparral near the
coast and is found only in San Diego County and adjacent Baja California.

6. Disruption of Solar Wind Antennae System (See the Following Mitigating
Measure)
/
Implementation of the project without adequate mitigation will inter-
fere ;with the University of California's Solar Wind Antennae System
operated by the Physics Department of the University of California,
San Diego campus. This antennae system is unique in the United States
and is part of an extensive and complex experiment funded by the
National Foundation. This electrically sensitive antennae system,
.located on the Dawson-Los Monos U. C. Preserve, slightly less than
1 mile from the project site, will be affected by electrical inter-
ference generated by the proposed project if effective mitigation
measures are not implemented.
Mitigating Measures
A. All new electrical lines should be undergrounded to prevent above-
ground level electrical arcing (common to above ground level trans-
mission lines) in the vicinity of the solar wind antenna system
such that electrical interference is minimized.
B. In consideration of'the need of- the University of Califoi-nia for
a radio-quiet environment in the vicinity of the project, the
applicant will consult with the University during project design,
and will work with the University to mitigate any radio interfer-
ence resulting from the project.
7. Grading (No Mitigating Measures Proposed)
Approximately 54,000 cubic yards of earthwork is proposed for 4.5
acres of the site, resulting in grading of 12,000 cubic yards per
acre. The grading will be balanced cut and fill operation with a
maximum cut of 24.5 feet-and minimum fill of 13 feet.
8. Agriculture (No Mitigating Measure Proposed)
Project implementation will have an adverse effect on agriculture
by removing 10 acres of land from agricultural use within the coastal
dependent agriculture zone.Las Flores soils (Class IVe; Storie Index
= 31) are found on approximately 10 acres of the project property.
. Those soils are considered to be valuable for the cultivation of flowers,
range, and truck crops.
