The project site is currently vacant and undeveloped but was previously approved for 35 air-space residential condominium units (CT 15-01/PUD 15-03/SDP 15-02/HDP 15-02/HMP 16-02 - CASCADA VERDE). 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 Division: 1. General Plan and zoning designations for the property are as follows: a. General Plan Land Use Designation: R-15, Residential (8-15 du/acre) b. Zoning: Residential Density-Multiple (RD-M) Zone 2. The project requires the following permits: a. Site Development Plan (SOP) b. Hillside Development Permit (HOP) c. Habitat Management Permit (HMP) 3. Pursuant to CMC Section 21.53.120(A), no building permit or other entitlement shall be issued for any multi-family residential development having more than four (4) dwelling units or an affordable housing project of any size unless a Site Development Plan (SOP) has been approved for the project. Therefore, as noted in Comment No. 2 above, an SOP is required and shall be processed pursuant to the provisions of CMC Chapter 21.06. 4. Unless exempt pursuant to CMC Section 21.95.040, no person shall grade, erect, or construct into or on top of a slope which has a gradient of fifteen percent or more and an elevation differential Community Development Department Planning Division I 1635 Faraday Avenue Carlsbad, CA 92008-7314 I 442-339-2600 www.carlsbadca.gov PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 2 greater than fifteen feet without first obtaining a hillside development permit (HOP) pursuant to CMC Chapter 21.95. The project is proposing to grade into a continuous slope along Alicante Road and Altisma Way consisting of approximately 460 linear feet. The Slope Analysis Exhibit, Sheet C2, submitted with the preliminary review application describes the slope as manufactured. This slope includes a gradient of greater than 40% an elevation differential exceeding 15 feet. No record of a previous authorized grading permit for these manufactured slopes has been presented. Therefore, the project is not exempted under CMC Section 21.95.040; and an HOP is required as noted in Comment No. 2 above. As such, a formal submittal of the project will need to demonstrate conformance with the Hillside Development Regulations and Hillside Development & Design Guidelines. As part of any formal submittal, please be sure that project exhibits address all requirements listed under CMC Section 21.95.130 -Hillside Mapping Procedures and CMC Section 21.95.140-Hillside Development and Design Standards. The Hillside Development & Design Guidelines may be reviewed online at: https://www.carlsbadca.gov/home/showpublisheddocument/270/637425976541270000 5. The Slope Analysis Exhibit (Sheet C2) that was submitted with the preliminary review application does not follow proper Hillside Mapping Procedures as outlined in CMC Section 21.95.130. Namely, the slope range that is presented overlaps categories and therefore the analysis is determined to be inaccurate at this time and cannot be used for providing accurate responses to requests within this application. A formal submittal will be required to adhere to the requirements of this chapter. 6. The "net area for density calculations" column that is presented within the Slope Analysis Exhibit, Slope Analysis and Density Calculations (Sheet C2) does not comply with CMC Section 21.53.230(d), where it is stated that no more than 50% of the portion of a site containing 25% to 40% slopes may be utilized for calculating allowable residential density. Instead, this column states that the entire 3.677 gross acres is fully developable and qualifies for unit yield purposes. 7. On the Slope Analysis Exhibit, Sheet C2, the area of slopes with corresponding Exclusion Notes 1 and 2 labeled on the map appears logical and accurately depicted with exception to any changes that may occur because of Comment 5 above. As part of the required Slope Analysis Exhibit, please be sure to reference CMC Section 21.95.140(8) next to these Exclusion Notes. 8. As it relates to the proposed number of residential units yielded for this site and residential types, please see the Housing & Homeless Services Departments comments below. Where they defer to Planning Staff regarding confirmation of acreage and density calculations, Planning Division staff cannot provide until Comments 5-6 above have been more fully addressed. Also, the California Housing and Community Development Housing Accountability Division is available for inquires on interpretation of state law. If this is an area of disagreement, that is a potential venue to get clarification on this section. The following link to Informational Bulletin IB-110 also offers access to another venue for addressing disagreements or conflicts: https:ljwww.carlsbadca.gov/home/showpublisheddocument/10544/638252682072000000 PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Pa e 3 9. The preliminary review application materials discuss a decomposed granite trail extending north in a linear spur running parallel to the rear yards of existing residential units and ending at a small seating area located within proposed open space area. This amenity presents a potential attractive nuisance that could cause indirect or direct impacts into the habitat areas. Consider removing from the project design. We recommend as part of the Enhanced Stakeholder Outreach process (discussed below) that this be exhaustively discussed with interested parties. 10. The parking garage, as depicted in the preliminary review application materials, does not appear to meet the definition of a basement, and thus would need to be included as part of overall building height of the structure and would also need to meet building setbacks. As part of the state density bonus discussion, and use of requested incentives, this feature of the building would also need to be included for setback deviation. 11. State density bonus parking standards must be requested to be used. As part of formal application submittal, Density Bonus Supplemental Checklist, Form P-l(H) is required to be completed. As part of that completeness submittal item, please be sure to include this request pursuant to Gov. Code §65915. 12. Development Project Public Involvement Policy (Form P-21). As part of any formal application submittal, please note that this project as proposed will be subject to both: Part A -Notice of Project Application Process and Part B -Enhanced Stakeholder Outreach, in that the project requires (1) a Site Development Plan, and (2) is proposing residential development consisting of 50 or more residential units. The Development Project Public Involvement Policy (Form P-21) may be found on the city's website at: https://www.carlsbadca.gov/home/showpublisheddocument/452/637843403622900000 Please be aware that Part A of this requirement is intended to be completed within the first 30 days of application submittal. 13. For Parking Garage Standards, please see CMC Section 21.44.060(A)(3)-Table D "Enclosed Parking Garage with Multiple, Open Parking Spaces. 14. For any architectural elevations and section details, these items shall indicate compliance with Carlsbad building height definition as defined in Section 21.04.065 of the Carlsbad Municipal Code. We understand building height maximums are being exceeded and are listed as a requested incentive under state density bonus law. However, these architectural items on the plans will still need to depict building height accurately according to city zoning regulations. For addition assistance and understanding, please review the Guide to Measuring Building Height, which can be found on the Planning Division's website at: https://www .ca rlsbadca .gov /home/showpubl isheddocu ment/268/637 425976538130000 PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page4 15. On page 15 of 23, Section 4(e) of the Cascada Redesign letter, it references relaxation of standards pursuant to CMC Sections 21.53.120(A) and (B). Please note this section of code was recently amended by Ordinance CS-422 dated May 10, 2022. Enclosed is a copy of the amended ordinance. 16. The AO prepared architectural sheets, submitted on 8.5"xll" reduced sheets with the preliminary review application materials, are too small to read or analyze. Therefore, no comments as it relates to these architectural exhibits has been prepared. 17. California Environmental Quality Act. A new CEQA evaluation will be required for a new project. Applicant requests that the "Project Alternatives" assessment consider the prior approval of Cascada Verde. Project Alternatives are only required if an Environmental Impact Report (EIR) is required. After there is receipt of a proposed project, an initial study will be required to determine potentially significant impacts and mitigation. This can review previous environmental documents and will determine the appropriate CEQA process for the proposed project. It is recommended that specific review and evaluation of habitat impacts and consultation with other agencies occur at this time. If it is determined an EIR is required, the procedures outlined in Carlsbad Municipal Code Section 19.04.120 will apply to preparation of the EIR. 18. Cultural Resources Report. The development of the proposed project will require excavation in an area of the city known to have a moderate sensitivity as it relates to archeological resources. Please direct your consultant to the city's Tribal, Cultural and Paleontological Resources Guidelines. These guidelines were adopted after the previous project approvals. Please note that any archeological pedestrian survey of the site for the cultural resources study shall also include a Native American monitor during the survey. The city's Tribal, Cultural and Paleontological Resources Guidelines may be found on the city's website at: https://www.carlsbadca.gov/home/showpublisheddocument/254/637425976516870000 These guidelines were adopted after the previous project approvals. An updated report will need to be submitted demonstrating compliance. 19. Paleontological Resources Report. The development of the proposed project will require excavation in an area of the city known to have a high sensitivity as it relates to paleontological resources. Please direct your consultant to the city's Tribal, Cultural and Paleontological Resources Guidelines. The city's Tribal, Cultural and Paleontological Resources Guidelines may be found on the city's website at: https:ijwww.carlsbadca.gov/home/showpublisheddocument/254/637425976516870000 These guidelines were adopted after the previous project approvals. An updated report will need to be submitted demonstrating compliance. 20. Noise Study. It is acknowledged from the preliminary review application materials that a new noise study will be completed. PHE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Pa e 5 Land Development Engineering Division: 1. Contact Nick Gorman in the Traffic Division via email at Nick.Gorman@carlsbadca.gov, a division of the Public Works Department, to determine if a Scoping Agreement is required. Scoping Agreements are used to determine if a Local Mobility Analysis is required and the scope of analysis. Submit either an approved Scoping Agreement or correspondence from the Traffic Division indicating one is not required. Provide ADT and peak hour trips per generation rates from SAN DAG Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region on the site plan/tentative map. 2. If a Local Mobility Analysis is required, refer to the Transportation Impact Analysis Guidelines at: https://www.carlsbadca.gov/home/showpublisheddocument/328/637425982502330000 3. Depending on the CEQA determination, which is determined after the application for discretionary permits is submitted, a Vehicle Miles Traveled (VMT) analysis may be required per the Vehicles Miles Traveled Analysis Guidelines available at: https://www.carlsbadca.gov/home/showdocument?id=312. Preliminary analysis suggests that a VMT analysis will be required since the VMT/capita percentage of mean is 99.5%. The percentage must be below 85% to be exempt. 4. 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. 5. Based on a preliminary analysis it appears that this project is a Priority Development Project (PDP). All impervious surfaces being created or replaced (onsite and offsite) shall be included for treatment. Submit a Storm Water Quality Management Plan. Review the Hydromodification Exemption Map and Potential Critical Coarse Sediment Yield Area Map on the City website to determine if this criterion applies to your project. Based on our preliminary analysis, hydromodification appears to be applicable but the site does not appear to have any critical coarse sediment. The post construction stormwater treatment BMPs shall be shown on a conceptual grading and drainage plan with the discretionary application. 6. Based on this project's general land use of R-15, this project is NOT subject to the City of Carlsbad trash capture requirements. 7. Provide a Preliminary Title Report (current within the last six (6) months). 8. Annotate and delineate all existing easements and encumbrances listed in the Preliminary Title Report on the site plan. If any vacations or quitclaims are planned with this development annotate on the site plan. The drainage easement and water easement that traverses the location of the proposed building shall be abandoned by either separate instrument via application for city plan PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 6 check or if a subdivision map is processed on the property, abandonment via the map. 9. A Preliminary Hydrology Study including map and calculations is required to demonstrate capacity/sizing of proposed and existing storm drain infrastructure, including the new storm drain discharging from Altisma Way and the existing storm drain discharging from Altiva Place. Impacts to the 72-inch storm drain channeling flow under Alicante Road will also require analysis since the proposed development will increase flow to the channel. Show 100-year storm hydrologic calculations before and after development for each drainage basin. Although the property is not located within a FEMA designated flood plain, the development is located adjacent to a creek subject to variation in elevation flows that would appear to potentially extend into the building footprint during larger storm events. Therefore, analyze the pre and post development flood plain and floodway elevations and boundaries for a 100-year storm event. The results could have a significant impact on the building location and design since the building is currently proposed near the elevation of the creek channel. The lowest floor elevation shall be located above the flood plain elevation. Refer to Section 21.110.160 of the Carlsbad Municipal Code for additional guidance on construction in a flood plain and demonstrate compliance on the preliminary grading plan. 10. A preliminary geotechnical report is required to evaluate the feasibility of the project. Please submit a current geotechnical report with description and evaluation of the proposed project with your application for discretionary permits. Guidelines for preliminary geotechnical studies are available on the City of Carlsbad Engineering website. Based on previous reports prepared for the proposed 35-unit condominium development, alluvium up to 10 feet in depth was recommended for removal and recompaction as well as caissons embedded in bedrock or terrace deposits for the proposed building at the southwest corner of the project site. Shallow groundwater was also encountered. Given the location of the proposed apartment building being within the vicinity of the aforementioned condominium from the previous project, many of these recommendations or variations of these recommendations should be anticipated for the proposed apartment building. 11. Per CMC Section 15.16.060 this project will require a grading permit and grading plan. Shoring will be required to construct the building as shown. Plot proposed shoring on the conceptual grading plan and cross sections with the discretionary permits. Where shoring is not proposed, plot temporary vertical and 1:1 back-cuts consistent with the recommendations from the geotechnical engineer. A detailed shoring design shall be included with the construction grading plans processed after discretionary plans are approved. 12. A separate improvement plan for work within the right-of-way is required for this project. New sidewalk and a driveway approach will be required on Altisma Way. New ADA compliant pedestrian ramps will be required wherever compliance is needed along the property street frontage. At final design, design of the public improvements shall be reviewed by a Certified Accessibility Specialist person (CASp) for compliance with current ADA requirements. Street pavement shall be restored with grind and overlay where conditions warrant. Currently there is cracking on Altisma Way and Alicante Street that would warrant grind and overlay for half the street fronting the property. PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Pa e 7 13. Add an access ramp from Alicante Road to the basin of the creek channel equivalent to the design proposed with the previously approved 35-unit condominium project under CT 15-01. 14. This project shall utilize City of Carlsbad Survey Control Network established on Record of Survey Map 17271, NAD83, Zone VI, 1991.35 Epoch for horizontal control and NGVD 29 datum for vertical control per City Engineering Standards Volume 1, Chapter 2. 15. Indicate the earthwork quantities (cut, fill, import, export, remedial) proposed for the project in cubic yards. Include remedial grading quantities on the plan which may be extensive given the depth of alluvium soils needing removal and recompaction as identified in previous geotechnical reports. 16. Include a separate civil plan with only existing features (topography, utilities, easements, infrastructure, etc.) shown on the property with your plan set submitted as part of your application for discretionary permits. 17. Provide the method of draining each lot. Unless otherwise specified by a geotechnical engineer, method of drainage shall comply with California Building Code (latest version) section 1804.4. 18. Delineate all retaining walls that will be utilized on the project site and show top of wall and bottom of wall elevations, including at the highest and lowest points. Indicate maximum height of retaining wall measured from bottom of footing to top of wall and maximum height measured from finish surface to top of wall. 19. Trees along the Altisma Way frontage are included in the city's street tree inventory. Plot the trees and indicate on the site plan which trees would remain or be removed. Proposed removal of street trees will require approval per CMC Section 11.12.090. Coordinate with the Parks & Recreation Department for additional information. 20. Show existing lot line bearing and distance. 21. Show location and dimensions of all accessways and pathways as required for compliance with Title 24 -State Accessibility Requirements. 22. Provide typical street cross sections for existing frontage streets. Provide existing right-of-way width and existing improvements and proposed improvements. 23. Delineate and annotate all proposed driveways and driveway widths. Construct driveway to San Diego Regional Standards Drawing (SDRSD) G-14A and City of Carlsbad Standard Drawing GS-12. 24. Include parking garage design with your site plan. If the project is planning to connect a storm drain to the sanitary sewer for emergency and incidental flows in the underground parking garage, the developer shall apply for a provisional source control permit with Encinas Wastewater District. Discharges cannot flow to a BMP unless the BMP completely contains the flow. This flow cann~t enter the public drainage system (MS4) since the flow would be an illegal discharge as a non- storm water discharge. PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 8 25. Show all existing utilities and callout size for: water, sewer, storm drain, underground dry utilities, overhead lines, traffic signals, street lights and any other pertinent utility in Alicante Road, Altisma Way and Altiva Place that affects the property. 26. All transformers and electrical facilities solely serving this project site shall be located on site and outside of the public right-of-way. Plot the location of the transformer serving the project. 27. Project property is located within the jurisdiction of the Leucadia Wastewater District (LWD). Submit the Sewer Study to the LWD for review and provide letter from LWD verifying acceptable options for connecting to their public mains as outlined in the study. 28. Public potable water mains along project frontages must meet minimum design diameter and material as specified in City of Carlsbad Engineering Standard Vol. 2 Section 3.2.2 for water and Volume 1 Section 6.2 for sewer. Utility replacement and/or upsizing may be required as a condition of development. 29. The property is located within the Carlsbad Municipal Water District. Locate fire service, backflows, potable and recycled water services, meters, landscape irrigation services for the new development in compliance with 2022 Carlsbad Engineering Design Standards requirements. 30. Identify the location of the trash enclosure. The trash enclosure shall be designed to the City of Carlsbad standard drawing GS-16 to the greatest extent possible. Any deviation from the City of Carlsbad standard may require approval from Republic Services to ensure that the trash enclosure is serviceable. 31. Meet with the Fire Department to identify the necessary fire protection measures required for this project (access, fire hydrants, sprinkler system, on-site circulation, emergency access, etc.) 32. Plot stopping sight distance at all driveways and corner sight distance at all street intersections. 33. Address the comments on the attached redlined plan. 34. Please be advised that a more in-depth review of the proposed development will occur with the discretionary permit application when a more complete design of the project is provided. Housing and Homeless Services Department: Housing & Homeless Services staff have completed a review of the above-referenced project for pre- application completeness. The Housing & Homeless Services finds that the project as proposed does not demonstrate compliance with State law and City codes. The applicant should submit an application and address the following: 1. Total Units & Affordability -Applicant is applying for additional units, incentives, and waivers in accordance with density bonus provisions found in Government Code §65915 and Carlsbad PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 9 Municipal Code Chapter 21.86. Based on projected gross acreage (Planning needs to confirm acreage and density calculations) and project as proposed, the following are HHS calculations. A Acreage 3.677 B Max Density per Acre 15 C Base Units (Ax B) 3.67 X 15 = 55.2 rounds up to 56 units D Requested Bonus (C x 50%) Base Units x 50% 28 units E Total Units (C + D) Base Units+ Bonus 84 units F Required Affordable Units 56 X 15% = 8.4, rounds up to 9 very per GC 65915 (C x 15%) low-income units G Required Affordable Units 84 X 12.5%= 10.5 units, rounds up to 11 Per CMC 21.85 (Ex 12.5%) very-low-income units H Total Affordable Unit Count 9 affordable units (F) count toward required units (G), so (The higher of For G) total affordable unit count is 11 I Accessory Dwelling Units See discussion below. A maximum of two (2) detached (per GC 65852.2 (e)(l)(D)(i)) AD Us permitted for this project. J Total Unit Count (E + I) 84+2 = 86 units 2. lnclusionary Requirement -Project is also subject to Carlsbad Municipal Code Chapter 21.85, requiring fifteen percent of the total residential units be affordable for lower income households. Carlsbad Municipal Code (CMC) Section 21.85.070 provides alternatives to construction of inclusionary units, including reducing the required number of inclusionary units to twelve and a half (12.5%) percent for projects that restrict all affordable units to extremely low or very-low- income households. Under this alternative, this project is providing very-low-income units pursuant to Government Code §65915, and therefore, the very-low-income inclusionary units shall be twelve and a half (12.5%) percent of the total residential units approved by the final decision-making authority, including density bonus units. Therefore, the affordable units required by this code section is 11 units (84 x 0.125 = 10.5 rounded up to 11). The project would be required to provide 11 very-low-income units based on Carlsbad Municipal Code Chapter 21.85. The project is required to provide 11 affordable units, and per CMC Section 21.85.030, a minimum of 10 percent of the affordable units shall have three or more bedrooms. The project is required to provide 11 inclusionary units x 10% = 1.1 or one, three-bedroom unit is required. Additionally, per CMC Section 21.85.040(G) -inclusionary units shall be reasonably consistent or compatible with the design of the total project in terms of appearance, materials, and finished quality. 3. Accessory Dwelling Units -There are two ways in which State law permits AD Us with multi-family residential projects: detached AD Us and conversion ADUs. A detached ADU is a completely free- standing structure that is unattached to the main multi-family structure; a conversion ADU converts existing "non-livable space" in the main multi-family structure into a new ADU (e.g., a storage room, boiler room, passageway, attic, basement, or garage). The maximum number of conversions AD Us depend on how many units are already on the property. At least one conversion ADU is permitted, and beyond that, the number of allowed conversion AD Us is up to 25% of the number of existing units already on the property. State law also allows for a maximum of two (2) PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 10 detached ADUs for a proposed (new) multi-family residential project, subject to height, setbacks and other requirements. The applicant has misinterpreted the State law regarding AD Us on multi- family residential projects. The project as proposed, does not allow for conversion of existing space to create new ADUs, as this site is undeveloped. Therefore, under State law, Government Code 65852.2 (e)(l)(D)(i), the project is permitted a maximum of two (2) detached ADUs on a proposed multifamily residential project. Government Code 65852.2 (e)(1) citation: (e) (1) Notwithstanding subdivisions (a) to (d), inclusive, a local agency shall ministerially approve an application for a building permit within a residential or mixed-use zone to create any of the following: (D) (i) Not more than two (2) accessory dwelling units that are located on a lot that has an existing or proposed multifamily dwelling but are detached from that multifamily dwelling and are subject to a height Hmitation in clause (i), (ii), or (iii), as applicable, of subparagraph (D) of paragraph (2) of subdivision (c) and rear yard and side setbacks of no more than four feet. (A, B related to single family, C related to existing multifamily) (C) (i) Multiple accessory dwelling units within the portions of existing multifamily dwelling structures that are not used as livable space, including, but not limited to, storage rooms, boiler rooms, passageways, attics, basements, or garages, if each unit complies with state building standards for dwellings. (ii) A local agency shall allow at least one accessory dwelling unit within an existing multifamily dwelling and shall allow up to 25 percent of the existing multifamily dwelling units. 4. Affordable Unit Distribution -Applicant should be aware that State law (Health and Safety Code Section 17929 ("AB 491")) requires the affordable units to be distributed equitability throughout the project. Health and Safety Code Section 17929 (a)(2} citation: (a) (1) For a mixed-income multifamily structure, both of the following shall apply: (A) The occupants of the affordable housing units within the mixed-income multifamily structure shall have the same access to the common entrances to that structure as the occupants of the market-rate housing units. (B) The occupants of the affordable housing units within the mixed-income multifamily structure shall have the same access to the common areas and amenities of that structure as the occupants of the market-rate housing units. PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 11 (2) A mixed-income multifamily structure shall not isolate the affordable housing units within that structure to a specific floor or an area on a specific floor.

The planting palette shall include: a. Common and botanical plant names. b. Tree types and quantities. c. Shrub types and spacing with general layout. d. Ground cover types and spacing. e. Proposed plant sizes (either by number or percentage(%) of total quantity). 8. Please note that Trees shall not be planted within a public utility easement unless otherwise approved by the City. 9. Please specify/label on the landscape plans each specific BMP design for all bio-retention areas as one of the following (per attached Appendix E: BMP Design Fact Sheet): a. Section A PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 12 b. Section B c. Section C d. Section D For each basin clarify on the plans if to be lined or not and indicate if each section is bio-retention only or a flow through planter. All plantings within the basin perimeter must be plants selected from Appendix E: BMP Design Fact Sheet (attached) and appropriate for basin bottoms, side slopes, and each of the four Sections as defined in Appendix E. 10. Please provide a Maintenance Responsibility Exhibit in conjunction with the required Landscape Concept Plans. The Maintenance Responsibility Exhibit shall be prepared at a scale and size (preferably one sheet) that provides an overall view of the project and shall clearly identify the various areas of landscape maintenance responsibilities (private, common area/homeowners" association (HOA), City, etc.). 11. The Landscape Manual indicates that landscape plans are to feature ground cover, shrubs, and trees to screen elements of unsightliness and screen/soften new improvements. The Landscape Manual also indicates that landscaping shall be used to accentuate and enhance architecture. 12. Plants in a transitional area (adjacent to native vegetation) shall consist of a combination of site adaptive and compatible native and/or non-native species and shall conform to the Landscape Manual requirements in Section 5 -Fire Protection Requirements. 13. Please add a note to the plan to indicate that all utilities are to be screened. Landscape construction drawings will be required to show and label all utilities and provide appropriate screening. 14.

PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 15 Fire Department: 1. The proposed submittal did not include a site plan that showed buildings, fire access lanes, proposed elevation drawings, etc. To provide accurate fire comments on the proposed development, these shall be provided. Please be aware that pending changes to fire hazard severity zones at the state level could impact building construction requirements for this project. Public Works Department, Transportation: 1. Transportation Impact Analysis (TIA) Scoping Agreement: Due to the proposed changes in the project's site plan and number of dwelling units it appears a TIA report may be required. Please submit a TIA scoping agreement as provided in Appendix A of the City's Transportation Impact Analysis Guidelines (attached). Public Works Department, Utilities-Design: 1. Submit a Water Study, analyzing existing and proposed demands for the public water distribution system. The required water study shall include domestic meter and fire sizing criteria, as well as modeling of public distribution system in response to on-site water demands per the CMWD 2019 Potable Water Master Plan and fire flow requirements per CFC Table B105.1 as modified by the City of Carlsbad fire department. 2. The project proposes to remove on-site public 14-inch diameter water main. This water main is necessary to support the public water distribution system. If the 14-inch water main is removed, it must be replaced outside of the proposed building footprint. A new watermain in Altiva Place and new connections in Alicante Road may be required. 3. Show proposed fire, water, and irrigation connections with meter and backflow sizing. 4. Please note that the sewer study was not reviewed as the project is located within the Leucadia Wastewater District. All public sewer improvements and studies should be routed to Leucadia for review. Habitat Management: 1. The Cascada Verde Project has received permits and approvals from the City of Carlsbad and wetland permitting agencies. These permits and approvals are still active. Due to changes in financial and real estate conditions, the applicant has chosen to redesign this project; therefore, this project is being evaluated as a redesign of an existing approved project rather than as a new project. The focus of this HMP review is whether the redesigned project is a biologically superior alternative to the original project. 2. The applicant must submit a revised biological technical report consistent with the most current Guidelines for Biological Studies. This report must include the following: impact acreage by habitat type, mitigation details, including wetland creation component; impact map showing project impacts and fuel modification zone boundaries overlaid onto newly mapped vegetation PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 16 communities; results of surveys for least Bell's vireo and coastal California gnatcatcher. Explain that fuel mod zones will be revegetated with low fuel native species and be maintained as habitat that will meet Fire Dept FMZ Condition B standards (Natural Slopes with Native Vegetation; See Chapter 5 of city's Landscape Manual). 3. Describe and justify results of remapped vegetation and jurisdictional delineation. Explain why there is no mapped native grassland. 4. Impacts: Include all areas within limits of grading and vegetation removal, including FMZ 1 and 2, decomposed granite walkway, trail, any sewer-related structures, etc. 5. Provide tables comparing the impacts and mitigation of the original design vs. the redesign. IMPACTS (source: adopted MNO) MITIGATION Project Impacts {AE ..

The comparison table in the submittal states that CDFW jurisdictional impact was reduced 44%, but shows original plan impacts of 0.54 acre and revised design impacts of 0.97 acre, which is an increase not a decrease. 7. Fuel modification zones a. FMZ 1-The planting palette appears to be more native landscaping than habitat. Revise plant palette and clarify that there will be no permanent irrigation (keep existing irrigation note). b. FMZ 2 seeds, if added, should be sourced locally (within 25 miles). Name the habitat type you are restoring to. 8. Describe all the ways in which this redesign is a biologically superior design. For example: clustered development near roadway; no creek crossing; less impacts to habitat and wetland resources; more buffer function for creek; more preserved habitat onsite; may be completely mitigated onsite; some enhancement of the site by removal of non-native trees and planting with native species; etc. 9. Project includes a trail on the north side, and a five (5) foot-wide decomposed granite walking path on the south side of the building. It seems like this could invite people to go into the adjacent habitat to hang out. Describe how this will be avoided. 10. Address HMP adjacency standards Building Division: The Building Division has no comments to provide regarding this PRE submittal for conceptual plan review. However, the following comments are being provided courtesy of the Building Division and will need to be clearly detailed in a final design prior to submitting for building permit construction plan review: PRE 2023-0019 (DEV14027) -CASCADA VERDE REDESIGN July 25, 2023 Page 17 Carlsbad requirements: CLIMATE ZONE 7 SEISMIC (R=6.5) = .12 W; SDC = D; SDS.:: .75, :51.00; Dl/D2 RAINFALL ("/hr.): 3.7" WIND VELOCITY: 96mph 1. This project consists of building with more than two dwelling units and may be subject to CBC Chapter 11A and/or 11B accessibility requirements and other/ Federal accessibility requirements depending on the funding source(s). New apartments of three or more dwellings per building and new condominiums of four or more dwellings per building are defined as covered multifamily dwellings subject to CBC Chapter 11A accessibility requirements for accessible/ adaptable units. 2. Funding sources such as CTAC may trigger additional accessibility requirements above the minimum amounts required by the California Building Code. If applicable, please list those additional requirements, if applicable, in chart form on the cover sheet and provide details on the plans. 3. Is the project constructed by, for, or on behalf of a Title II entity or part of a Title II entities program that provides housing? If yes, then the 2010 ADAS applies. 4. Is the project receiving Federal financial assistance, and if so, is it coming from HUD? If it's a Home Key Project, then the answer to that is yes. Therefore, it must comply with HUD 504 regulations with the options of either using UFAS or the HUD Deeming Notice that allows the use of the 2010 ADAS with certain exceptions. 5. Property line between each dwelling: The occupancy would be defined as R-3. R-3 occupancies must be separated by (2) one-hour walls or (1) two-hour wall for CRC 302. 6. Property line around the perimeter of the entire property: The occupancy will be defined as R-2 requiring a one-hour separation between dwellings with separate utilities Carlsbad Climate Action Plan. This project will trigger Carlsbad Climate Action Plan compliance for the following: 7. New residential construction is required to comply with CAP sections 2A, 3A and 4A for solar, water heating and EV charging. (each new dwelling requires an EV charger installed). 8. The Carlsbad form B-55 will be required to be imprinted onto the plans to be approved for a permit. 9. 2022 CRC also requires ESS ready provisions to be designed into new residential construction. 10.
