DATE; October 18, 1977 City Atty DEPARTMENT: planning City Mgr. 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. EXHIBITS Resolution No. 1405 Memorandum to City Council from Planning Director dated September 30, 1977 Staff Report dated September 28, 1977 Exhibit "A" dated 9/1/77 tilK Mitigating Measures Location Map RECOMMENDATION It is recommended that the City Council deny the appeal and direct City Attorney to prepare documents as per Planning Commission Resolution 1405. If the City Council action is contrary to this recommendation, it is recommended that City Council accept report dated September 30, 1977 and take final action at this hearing. Council Action: 10-18-77 Council granted the appeal and directed the City Attorney to prepare the documents necessary approving CUP-140, with modifications to Conditions 3, 4, 6, 23, 26 and 27 as discussed by Council; as well as adding a condition re takina measures to reduce visibility of site to west.

HAGAMAN, Secretary .2 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.

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.

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: At the time when the City a General Plan (October 1974) subject property. The site parcel which was purchased landing system for Palomar the airport approach area ( designated the remainder of Land Use Map. The Planning 58 acres of the open space of the solid waste shredder corporation yard (central 1 maintenance services.) pproved the amended Land Use Element of the , the County had no intended use for the is, in fact, a portion of a larger 230 acre by the County to provide an instrument Airport. Consequently, the City designated 58 acres) as G (Governmental Facility) and the site (172 acres) as Open Space on the Commission is considering the request that area be designated G to allow for construction 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. ATTACHMENTS Exhibit A, dated 9/1/77 Location Maps CUP-140 EIR Mitigation Measure DHW:TH:BP:jp 9/22/77 -9- ENCLOSURE A 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.

E. Conduct a rectilinear post-hole series'to the satisfaction of the Environmental Analysis Division on each site that will be impacted by grading or project related activities to test for potentially buried cultural strata and map the location of all post-holes on a scaled nap with contours and a north arrow. F. All results of the post-hole series, the items specified in measures ARCHAEOLOGY (C) and (D) , and evidence that measures ARCHAEOLOGY (A) and (B) have been accomplished should be submitted in report form to the satisfaction of the Environmental Analysis 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. ENCLOSURE A-4 1. Arctostaphylos glandulosa Eastw. ssp. crassifolia (Jeps.) Wells. Thickleaf manza'nita This species is known only from San Diego County: along the coastal areas, in and around the Del Mar and Encinitas areas. This species is considered to be endangered as of 1974 (CNPS), and of declining population vigor. k \ A total of 11 individuals occur on the property. Federal R/E Status: Proposed as an Endangered species (both 1975 and 1976). 2. Adolphia californica Wats. Adolphia This species is known from southwestern San Diego County and ' northern Lower California: along dry canyons and washes within Chaparral and Coastal Sage Scrub plant communities (as defined by Hunz and Keck, 1949; 1950). This species is considered as of 1974 to be a .species of limited distribution, but not rare and/or endangered. Its population vigor is stable or increasing. A census of individuals was not conducted, however, estimates indicate that approximately 200 individuals on the property. Federal R/E Status: Not proposed as a threatened or an endangered species (1975 or 1976). 3. Selaginella cinerascens A.A. Eat. Spike-Moss This species is known from southwestern San Diego County and adjacent Lower California. Found on dry slopes and mesas within- Coastal Sage Scrub and Chaparral plant communities (as defined by Munz and Keck, 1949; 1950), this species is considered as of 1974 to be a species of limited distribution, but not rare and/or endangered. Its population vigor, relative endangerment, and rarity are not known with any degree of certainty, and its general population distribution is only poorly known. Several excellent mats of this species occur throughout the prop- erty in the areas dominated by native vegetation. Federal R/E Status: Not proposed as a threatened or an endangered species (1975 or 1976). ENCLOSURE A-5 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.
