The project site, an approximately 198.11-acre lot, is currently an existing operating disposal facility. In response to your application, the Planning Division has prepared this comment letter. Please note that the purpose of a preliminary review is to provide you with direction and comments on the overall concept of your project. This preliminary review does not represent an in-depth analysis of your project. It is intended to give you feedback on critical issues based upon the information provided in your submittal. This review is based upon the plans, policies. and standards in effect as of the date of this review. Please be aware that at the time of a formal application submittal, new plans, policies. and standards may be in effect and additional issues of concern may be raised through a more specific and detailed review. Planning: General 1. General Plan and zoning designations for the property are as follows: a. General Plan: Planned Industrial/Open Space (Pl/OS). b. Zoning: The parcel is within the following zones, Industrial -Industrial/Open Space (M/P-M/OS), but the project site is specifically within the Industrial (M) zone. 2. The project requires the following permits: a. Consistency Determination (CD). The project would install equipment to improve the quality of the water running off from the facility operations, it would not change the existing land use and would not expand the existing facility. Therefore, a Consistency Determination application would be adequate to review this project. Community Development Planning Division I 1635 Faraday Avenue Carlsbad, CA 92008-7314 I 760-602-4600 I 760-602-8560 f I www.carlsbadca.gov PRE 2021-0020 (DEV2021-0093) -PALOMAR TRANSFER STATION STORMWATER TREATMENT DESIGN June 24, 2021 Pa e 2 b. Environmental Review. As part of the existing Palomar Transfer Station facility the Planning Commission adopted a Resolution 5799 certifying Environmental Impact Report EIR 03-04 (SCH . . 2003071175) and adopting Findings of Fact, and a Mitigation Monitoring and Reporting Program. --' '•'Bas'ed bn .the information submitted, the proposed project is within the scope of that prior environmental document and no further environmental documentation is required per CEQA Guidelines Section 15162. The Application should show that this is consistent and that the application will continue to comply with all mitigation measures in the Certified EIR. 3. Staff has completed site visits in the past and it seemed much of the site was being fully utilized by operations of the facility. What functions, operations or features would be removed from the site in order to accommodate this new equipment? If there are operations that would be removed, if needed, where would they be re-located? 4. Would this water quality treatment system generate any new vehicle trips? 5. Would services from this facility be temporarily reduced, stopped or relocated for the interim during construction? If so, how would this be accommodated, and does it affect any of the property owners or tenants within the City of Carlsbad? 6. Development Standards. The project shall comply with the development standards of the Industrial (M) zoning designation and municipal code, including but not limited to the following: a. Industrial (Ml Ordinance. Show that the proposed project will not conflict with the development standards of the prescribed zone. Please refer to Carlsbad Municipal Code (CMC) Chapter 21.32 to ensure the project complies. 7. Parking. The parking requirements for industrial uses can be found in Carlsbad Municipal Code (CMC) Chapter 21.44. The conditional use permit for the transfer station may also establish specific parking requirements. From the current set of plans the new equipment does not appear to impact the existing site capacity for parking, but please note that the project would need to demonstrate that the required number of parking is provided consistent with the ratios in the municipal code and the conditional use permit, as appropriate. 8. Landscape. The project will need to maintain a quality landscaped appearance along Orion Road as well as screening of equipment from the street. Submittal of a landscape plan showing how this will be accomplished may be necessary. If 2,500 square feet or more of landscape area is disturbed as a result of this project, a formal submittal will need to include concept landscape and irrigation plans. The concept plans shall be designed in accordance with both the City of Carlsbad's Landscape Manual Policies and Requirements. The City of Carlsbad's Landscape Manual document can be found on the. Planning Division's web page at the _following address: https://www.carlsbadca.gov/home/showdocument?id=234 9. Climate Action Plan. New requirements related to the city's goals to reduce greenhouse gas (GHG) emissions may impact development requirements of this project. A formal application submittal will need to include a completed Climate Action Plan Checklist (Form P-30) to determine what requirements will apply to the project as set forth in the California Green Building Standards Code and in CMC Chapters 18.21, 18.30 and 18.51 which is available on the city's website at the following address: https://www.carlsbadca.gov/home/showdocument?id=3714 http://www.gcode.us/codes/carlsbad/view.php?topic-18 PRE 2021-0020 (DEV2021-0093)-PALOMAR TRANSFER STATION STORMWATER TREATMENT DESIGN June 24, 2021 Pa e 3 To the extent that new GHG reduction requirem.ents are in effect at the time of application for grading or building permits, the project will be required to comply with the effective requirements even if different than what is proposed in the project's planning approvals. GHG reduction requirements may impact, but are not limited to, site design and local building code requirements. If incorporating new GHG reduction requirements results in substantial modifications to the project after planning approvals are obtained, then prior to issuance of grading or building permits, the applicant may be required to submit and receive approval of a Consistency Determination or an Amendment application for the project through the Planning Division. Cultural Resources Assessment. If the project would disturb native soil, please submit a cultural resources assessment prepared by a qualified professional. The study shall comply with the city's Tribal, Cultural and Paleontological Resources Guidelines. Please be advised the Guidelines require a Luiseno Native American monitor to be present for any field survey or work conducted by an archaeologist. Further, a mitigation measure from the Certified EIR requires Native American monitoring of all grading activities. Please see the link below for additional information. https://www.carlsbadca.gov/home/showdocument?id-254 10. Noise Analysis. Because this is a new system added to the facility that could intensify the noise emitted from the site, a noise analysis analyzing the project's consistency with the General Plan and Noise Guidelines Manual may be necessary. The Noise Guidelines Manual can be found online at: https:ljwww.carlsbadca.gov/home/showdocument?id-238 https:ljwww.carlsbadca.gov/home/showpublisheddocument/4S2/637571085919570000 11. This preliminary review does not constitute a complete review of the proposed project and additional items of concern may be identified upon formal project application submittal. Please refer to the Development Permits P-2 checklist for all of the necessary required items prior to formal submittal, which is available on the city's website at the following address: https://www.carlsbadca.gov/home/showpublisheddocument/3760/637571045027400000 All necessary application forms, submittal requirements, and fee information are available at the Planning counter located in the Faraday Building at 1635 Faraday Avenue or online at https://www.carlsbadca.gov/departments/community-development/planning/planning-applications- forms. You may also access the General Plan Land Use Element and the Zoning Ordinance online at the website address shown; select Department Listing; select Planning Home Page. Please review all information carefully before submitting. Engineering: 1. Complete a Stormwater Standards Questionnaire. This questionnaire will guide you and the City in determining what type of reports and storm water mitigation must be completed to satisfy state arid City storm water quality requirements. The questionnaire can be printed from the following website link: https://www.carlsbadca.gov/home/showpublisheddocument/604/637426047018270000 Be aware that the project site is located within 200 feet of and drains to an Environmentally Sensitive Area (ESA). The Carlsbad Oaks North Habitat Conservation south of the subject site is designated an ESA and existing and proposed drainage discharges into this area. Per question 7 in step 3 of the PRE 2021-0020 (DEV2021-0093) -PALOMAR TRANSFER STATION STORMWATER TREATMENT DESIGN June 24, 2021 Pa e4 questionnaire, the criteria is 2,500 square feet of created or replaced impervious area draining to an ESA compared to several other questions using a 5,000 square foot threshold. This ESA criteria will likely be the most stringent criteria. If the project is still determined to be below this threshold, preliminary analysis suggests that the project would likely be a Standard Project and subject to installing site design and source control BMPs per Chapter 4 of the Carlsbad BMP Design Manual and per the Standard Project Requirement Checklist (E36) that will also need to be completed. The link to the form is at: http://www.carlsbadca.gov/civicax/filebank/blobdload.aspx?Blob1D=30141 Otherwise, the project will be defined as a Priority Development Project (PDP) and subject to submitting a Storm Water Quality Management Plan (SWQMP). Hydromodification requirements will also apply if a PDP. 2. Although the 130 cubic yards of grading does not exceed the threshold for requiring a grading permit, the rerouting of drainage does warrant a grading permit per section 15.16.020(6) and 15.16.060(6) of the Carlsbad Municipal Code since the drainage patterns are changing on site and because of potential increas.e in flow quantities and velocities at the points of discharge onto the conservation area. Please include a hydrology study with your application for grading plan check. 3. Clearly identify the right-of-way boundary on Orion Road, especially as it relates to the proposed basins at the southwest corner of the property. The plans shall clearly show that the basins and any other private facilities do not encroach into the public right. 4. Provide profiles of the proposed basins. Refer to Appendix E of the Carlsbad BMP Design Manual for design guidance. Basins shall percolate such that maximum drawdown times required per the Manual are not exceeded. Survey and identify the size of the existing basin overflow discharge pipe, flow line elevations, point of discharge, energy dissipators, etc. 5. Submit a title report with the application for grading plan check and list/plot all easements appearing in said report.
