Zoning: R-1-10000-One-family Residential Zone 2. The project requires the following permits: a. Grading Permit (see Land Development Engineering item 3 below) b. Building Permit 3. 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 Community Development Department Planning Division I 1635 Faraday Avenue Carlsbad, CA 92008-7314 I 442-339-2600 www.carlsbadca.gov PRE 2022-0035 (DEV2022-0121) -3229 HIGHLAND DRIVE September 22, 2022 Page 2 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/car1sbad/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. 4. Building Height. The maximum building height for a roof pitch greater than 3:12 is 30 feet. Preliminarily, it appears the project complies; however, compliance with the building height will be verified once the clarifying information is provided. 5. Basement Calculation/Buried Perimeter. On Sheet A3.01, please provide the percentages of the perimeter walls to show that at a minimum of seventy-five percent of the perimeter of the basement qualify. Based on a review of the basement appear to be incompliance however, percentages of each wall will be required at formal submittal. 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.

Land Development Engineering: 1. Complete a Stormwater Standards Questionnaire Form E-34. This questionnaire will guide you and the City in determining what type of reports and storm water mitigation must be completed to satisfy state and City storm water quality requirements. The questionnaire is located on the City of Carlsbad website. If the project is determined to be a priority development project (PDP) it will be subject to the post construction stormwater treatment BMPs designed per the City of Carlsbad BMP Manual. The grading plans will be required to detail the stormwater treatment facilities. Additionally, the preparation of a Storm Water Management Plan utilizing the stormwater template E-35 on the City of Carlsbad website will be required with the initial grading plan submittal. 2.
