The 0.93-acre parcel is currently vacant. 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: Residential, 0-4 dwelling units per acre (R-4); b. Zoning: One-Family Residential (R-1) Zone; and c. The project is located within the Appeal Jurisdiction and the Mello II segment of the Coastal Zone. The Coastal land use designation and zone are the same as the General Plan and Zoning referenced above. 2. The project requires the following permits, which require approval from the Planning Commission: a. Coastal Development Permit (CDP) for the development of two single-family homes and a minor subdivision. b. Minor Subdivision (MS) to subdivide the parcel into two or three lots; or, for a one-lot, air- space condominium project. It is not clear what will be proposed. c. Planned Development Permit (PD) will be required if small lots or condominiums are proposed pursuant to Carlsbad Municipal Code (CMC) Chapter 21.45. Pursuant to CMC Section 21.45.040, Table A, a one-family subdivision on small lots can be proposed in the R- 1 zone if the project site is contiguous to a higher intensity land use designation or zone, or Community Development Department Planning Division I 1635 Faraday Avenue Carlsbad, CA 92008-7314 I 760-602-4600 I 760-602-8560 f I www.carlsbadca.gov PRE 2020-0016 (DEV2020-0141) -GLAZEBROOK July 14, 2020 Pa e 2 3. 4. ~~~"f~_-:1_-I. ;:_ ,_;:, . .,,i:•J ____ , • •< ,. ' ii __ ,;,,, ,·,· :: ~1 ,:,;,•\""' ~ an existing project of comparable.. hipeh c{ensit)'il. Based on a review of the Assessor Parcel Map for the adjacent subdivision to the east, the density for the five adjacent lots is approximately 5.2 dwelling units per acre (du/ac). As the project proposes a density of 2.1 du/ac for two lots or 3.2 du/ac for three lots (see No. 5 below for density discussion), a small lot subdivision could be supported. Please confirm the density of the adjacent lots to the east and include this information on the project plans with the formal application submittal. The Housing Crisis Act of 2019 (SB 330) established a preliminary streamline application process for housing projects. It is not mandatory unless applicants seek the vesting and processing benefits offered under SB 330. Participation in the SB 330 streamline process would occur first, followed by the formal development application process required under Government Code (Gov. Code) §§ 65940, 65941, 65941.5, and Carlsbad Municipal Code (CMC) § 21.42.050. Acceptance by the city of a complete SB 330 Streamline Application (Form P-32) and fee will vest the project for 180 days in accordance with the ordinances, policies and standards in effect at the time the SB 330 Application is accepted. The city is finalizing the application form and process for SB 330 Streamline Applications. Please contact planning@carlsbadca.gov for more information. New requirements related to the city's goals to reduce greenhouse gas (GHG) emissions will likely 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. New GHG reduction requirements are related to energy efficiency, photovoltaic, electric vehicle charging, water heating and traffic demand management requirements, as set forth in the California Green Building Standards Code and in Carlsbad Municipal Code Chapters 18.21, 18.30 and 18.51 which is available on the city's website at the following address: http://www.qcode.us/codes/carlsbad/view.php?topic-18&frames-on To the extent that new GHG reduction requirements 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. 5. Project yield and density: The density range for the R-4 General Plan Land Use designation is Oto 4 dwelling units per acre (du/ac). Pursuant to the General Plan, the Growth Management Control Point (GMCP) for the R-4 General Plan Land Use designation is 3.2 du/ac. Based on a gross/net lot size of 0.93 acres, the proposed density is 2.1 du/ac and the allowable yield at the GMCP is 2.9 units (0.93 x 3.2 units= 2.9 units). Therefore, the proposed density is within the range for the R- 4 General Plan Land Use designation, but below the Growth Management Control Point of 3.2 du/ac. As the proposal to construct two (2) units falls below the GMCP by 0.9 units, one (1) dwelling unit will be deposited into the city's Excess Dwelling Unit Bank (EDUB). However, you are strongly encouraged to add one additional home to the project design as the density for three units is 3.2 du/ac. The goal is to increase housing units and develop at the GMCP if feasible. PRE 2020-0016 (DEV2020-0141) -GLAZEBROOK July 14, 2020 Pa e 3 6. Lot area. If a standard minor subdivision is proposed (i.e., not a small lot or condominium project), the minimum lot area when the zone implements the R-4 designation is 7,500 square feet. If a small lot subdivision is proposed pursuant to CMC Chapter 21.45, the minimum lot size is 5,000 square feet. 7. Lot width. Lots required to have an area of up to 10,000 square feet shall have a minimum width of 60 feet. If one or two panhandle lots are proposed, the parcel fronting Chinquapin Avenue would meet this requirement. If a small lot subdivision is proposed, the minimum lot width is 50 feet. 8. Panhandle lot. If one or more panhandle lots are proposed, the following requirements apply. Please see CMC Section 21.10.100 for additional information. a. If a two-lot subdivision is proposed with a panhandle lot, the buildable portion of the lot (i.e., exclusive of the panhandle) shall be a minimum of 10,000 square feet, or no less than 8,000 square feet if sufficient evidence to support such size is provided to the city. b.

B and C as shown on the red-lined plan . .. ··•---·-····--- PRE 2020-0016 (DEV2020-0141) -GLAZEBROOK July 14, 2020 Pa e 6 4. Show and label on the site plan and tentative map a 10 feet wide covenant of private cross-lot drainage easement over lots A and B for the benefit of lots Band C, as shown on the red-lined site plan. 5. Show and label on the site plan and tentative map a covenant of private stormwater BMP easement over lots A for the benefit of lots A, Band C, as shown on the red-lined site plan 6. Complete a Storm Water Standards Questionnaire Form E-34 to determine storm water quality requirements for this project. The questionnaire is available in the City website at: http:ljwww.carlsbadca.gov/services/depts/landev/engineering.asp 7. Based on the preliminary plans, staff determined the project qualifies as a Priority Development Project (PDP) and will be required to submit a preliminary Storm Water Quality Management Plan (SWQMP) with any discretionary application. The SWQMP shall be prepared in accordance with the City of Carlsbad BMP Manual (latest version). Use the City of Carlsbad SWQMP template for priority development project (Form E-35) available in the City website. The project SWQMP will determine the pollutant control BMP requirements. Note that this project is exempt from hydromodification requirements based on the exemption criteria provided in section 5.3 of Carlsbad WMAA. Provide BMP cross-sections and details on the preliminary site plan. 8. Identify the type of finish surfaces to determine the total impervious area and indicate on the site plan. Clarify if the project is proposing to use pervious pavers for the proposed drive aisle. If the project uses pervious pave rs, the pervious pavers shall be designed in accordance with SD-6B fact sheet, Appendix E.5 of the City of Carlsbad BMP Manual. Pervious pavers are considered site design BMP, designed as self-retaining BMP, primarily for direct rainfall only (not designed to treat additional impervious area). The use of pervious pavement results in the reduction of the impervious area, reduces the DCVand consequently reduces the footprint of the pollutant control BMP required for this project. 9. Submit a preliminary geotechnical investigation to determine feasibility of the proposed project. The study shall include design recommendation for any proposed pollutant control BMPs such as biofiltration basins, etc. Evaluation of the soil infiltration rates will be required at the proposed BMP locations. The study shall also include design recommendations for any proposed site design BMPs, such as permeable pavement adjacent to building structures to avoid negative impact to building foundation. 10.
