The Subdivision Map Would Facilitate Construction of 321 New Residential Units in One Building (24PLN-00162). CEQA Status: Exempt Pursuant to Assembly Bill 130 (Public Resources Code section 21080.66). Zoning District: CN, CS, RM-30, and RM-40. RECOMMENDATION Staff recommends the Planning and Transportation Commission (PTC) recommend approval of the Vesting Tentative Map to the City Council based on findings and subject to conditions of approval in the Draft Record of Land Use Action (RLUA) in Attachment B. EXECUTIVE SUMMARY The applicant requests approval of a Vesting Tentative Map to merge seven parcels located at 3508, 3516, 3626-3632 El Camino Real, and 524, 528, 530 Kendall Avenue to create one resulting 113,907-square-foot (2.61 acre) parcel. Through a separate Major Architectural Review Application, the applicant is proposing construction of a 321 rental unit project. Thirteen percent of the base units would be provided at a rate affordable to low income. The applicant filed a compliant pre-application in accordance with Senate Bill (SB) 330 on February 15, 2024 (24PLN-00047). Therefore, the project analysis is based on the applicable standards at the time the compliant SB 330 pre-application was submitted. In addition, the associated development project is considered a “builder’s remedy project” as defined in the recently adopted Assembly Bill (AB) 1893. On September 22, 2025, the applicant requested that the project be considered exempt under AB 130 [Public Resources Code section 21080.66]. This State regulation exempts infill housing projects meeting certain criteria from CEQA and sets strict timelines for City review and Item 2 Item 2 Staff Report     Packet Pg. 8     Item No. 2. Page 2 of 8 decision. The City evaluated the request and the project was found to meet the requirements set forth under AB 130 and is therefore exempt from CEQA.

Background. A. On September 9, 2025, Camino Real Development LLC & Kendall Investors, LLC submitted a subdivision map application for a Vesting Tentative Map to merge seven parcels into one resulting parcel for 3606 El Camino Real (“The Project”). The project site is comprised of seven existing lots: APN No. 137-08-088, approximately 10,838 square feet, developed with a commercial use; APN No. 137-08-016, approximately 5,199 square feet, an undeveloped parcel; APN No. 137-08-079, approximately 10,194 square feet, developed with a commercial use; APN No. 137-08-080, approximately 28,350 square feet, an undeveloped parcel; APN No. 137-08-077, approximately 38,058 square feet, developed with a multi-family residential use; APN No. 137-08-070, approximately 5,103 square feet, developed with a multi-family residential use; APN No. 137-08-081, approximately 16,275 square feet, developed with a commercial and residential use. Adjacent uses include a mix of commercial and low-intensity, one-story and two-story buildings, as well as low density residential uses surrounded by surface parking. B. Following staff review, the Planning and Transportation Commission reviewed the project and recommended ____________ on February 11, 2026, subject to conditions of approval. C. On _____________2026, the City Council held a public hearing in accordance with the City Council’s policies and procedures and __________the project subject to conditions of approval. SECTION 2. Environmental Review. The City, as the lead agency for the Project, has determined the project is exempt from California Environmental Quality Act (CEQA) in accordance with AB 130 [Public Resources Code section 21080.66]. Documentation to support the streamlined review is available as part of the public record on file with the Planning and Development Services Division. SECTION 3. Vesting Tentative Map Findings. A legislative body of a city shall deny approval of a Subdivision Map, if it makes any of the following findings (California Government Code Section 66474). The City Council cannot make these findings for the following reasons: Item 2 Attachment B - Draft Record of Land Use Action     Packet Pg. 17     2 1 0 4 0 1 1.That the proposed map is not consistent with applicable general and specific plans as specified in Section 65451: There is no adopted specific plan for this project site. The site is consistent with the Comprehensive Plan as described below. 2.That the design or improvement of the proposed subdivision is not consistent with applicable general and specific plans: There is no adopted specific plan for this project site. The proposed Vesting Tentative Map and related improvements is consistent with the Comprehensive Plan in that it facilitates housing development on a site designated for multi-family use within the urban services area, consistent with Goal 2 of the Housing Element and Goal L1.2 of the Land Use Element. The project includes 321 Units, 37 of which would be provided at a rate affordable to low income. The project improves the city’s jobs housing imbalance, consistent with the Transportation Element’s goals and policies. In addition, the project is proposed pursuant to the “builder’s remedy” of the Housing Accountability Act (Government Code section 65589.5) and is consistent with the standards set forth therein. 3. That the site is not physically suitable for the type of development: The Project site is suitable for multi-family residential development in that the majority of the parcels are identified as Housing Inventory Sites in the Housing Element. The project is also located within the City’s El Camino Real Focus Area, an area identified for high density housing within the City. The proposed parcel meets the minimum code requirements for the CN, CS, RM-30, and RM-40 zone districts with respect to lot area, width, and depth. The proposed number of apartment units created on the resulting parcel complies with the applicable densities set forth in the land use element and zoning code, consistent with the focus area standards. In addition, the project is proposed pursuant to the “builder’s remedy” of the Housing Accountability Act (Government Code section 65589.5) and is consistent with the standards set forth therein. 4.That the site is not physically suitable for the proposed density of development: The proposed improvements include a total of 321 multi-family residential units and results in 128 dwelling units per acre (DU/AC) across the resulting parcel. Because the site area is comprised of several lots, there are varying zoning designations across these lots, including portions zoned CN, CS, RM-30, and RM-40. In December 2023, the City Council adopted the El Camino Real Focus Area which established a local alternative to State Density Bonus Law along four properties on El Camino Real between Page Mill Road and Matadero Avenue. In accordance with the Housing Element Implementation, several additional sites were added to the El Camino Real Focus Area in July 2025, including the subject property. Item 2 Attachment B - Draft Record of Land Use Action     Packet Pg. 18     3 1 0 4 0 1 While the zoning code does not set a maximum density for projects on El Camino Real, the improvements are consistent with the density, floor area, and height allowances for sites within the Focus Area. Therefore, the project is physically suitable for the parcel. In addition, the project is proposed pursuant to the “builder’s remedy” of the Housing Accountability Act (Government Code section 65589.5) and is consistent with the densities permitted therein. 5. That the design of the subdivision or the proposed improvements are likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat: 6. That the design of the subdivision or type of improvements is likely to cause serious public health problems: 7. That the design of the subdivision or the type of improvements will conflict with easements, acquired by the public at large, for access through or use of, property within the proposed subdivision. In this connection, the governing body may approve a map if it finds that alternate easements, for access or for use, will be provided, and that these will be substantially equivalent to ones previously acquired by the public. This subsection shall apply only to easements of record or to easements established by judgment of a court of competent jurisdiction and no authority is hereby granted to a legislative body to determine that the public at large has acquired easements for access through or use of property within the proposed subdivision. Item 2 Attachment B - Draft Record of Land Use Action     Packet Pg. 19     4 1 0 4 0 1 property. New public utility easements will be provided to existing and proposed electrical utilities as part of this subdivision map as required in accordance with City of Palo Alto Utilities standards. New public access easements will be provided to provide the 12-foot effective sidewalk width along El Camino Real, consistent with project plans and City requirements.

A new 16-foot-wide turf-stone permeable paver driveway is proposed for site access. Three covered garage parking spaces are provided, with additional tandem parking available on the driveway in compliance with Zoning Code requirements. Additional improvements include new concrete masonry and iron bar fencing along the front yard and associated site improvements surrounding the residence. The project includes the removal of 15 existing native oak trees, 14 of which are protected. All removed trees would be replaced in accordance with the City’s Tree Technical Manual, with 60 native oak trees proposed. A detailed project description is provided in Attachment D, and project plans are included in Attachment E. Site Context and Background The project site is located near the end of the cul-de-sac of Laurel Glen Drive on an irregularly shaped, 4.23-acre, vacant parcel containing mature existing landscaping. The site is bordered by existing residential uses to the east and southwest. Arastradero Creek and the Arastradero Creek Trail run along the western side of the property, approximately 200 feet from the western property line and more than 500 feet from the proposed residential development. The proposed residence is oriented parallel to Laurel Glen Drive and is set back approximately 74 feet from the front property line, located just outside of an existing 30-foot-wide sewer line easement. The driveway and building placement are designed to follow the site’s natural Downtown Urban Design Guidelines (1993) South El Camino Real Guidelines (2002) Utilizes Chapter 18.24 - Objective Standards Individual Review Guidelines (2005) Within 150 feet of Residential Use or District Context-Based Design Criteria applicable SOFA Phase 1 (2000)Within Airport Influence Area SOFA Phase 2 (2003) Item 3 Item 3 Staff Report     Packet Pg. 31     Item No. 3. Page 4 of 7 topography, concentrating development on the flattest portion of the parcel. This approach minimizes grading and limits impacts to existing vegetation and trees. Site and Design Review: The process for evaluating this type of application is set forth in Palo Alto Municipal Code (PAMC) Chapter 18.30(G). Site and design review is intended to provide a review process for development in environmentally and ecologically sensitive areas, including established community areas which may be sensitive to negative aesthetic factors, excessive noise, increased traffic or other disruptions, in order to assure that use and development will be harmonious with other uses in the general vicinity, will be compatible with environmental and ecological objectives, and will be in accord with the Palo Alto Comprehensive Plan. ANALYSIS 1 The Comprehensive Plan designates the project site as Open Space/Controlled Development. This land use designation allows for limited development on private properties while prioritizing the preservation of open space resources and the natural character of the foothills. Residential densities ranging from 0.1 to 1 dwelling unit per acre are permitted in the Open Space designation, with limited allowances for additional units where secondary units are permitted. 1 The Palo Alto Comprehensive Plan is available online: bit.ly/PACompPlan2030 Item 3 Item 3 Staff Report     Packet Pg. 32     Item No. 3. Page 5 of 7 development of the parcel is consistent with the intent and density limitations of the Open Space / Controlled Development designation. The project is consistent with Policies N-1.1, N-1.2, and N-1.3 because development is clustered on the flattest portion of the site, substantial areas of private open space are retained, and removed trees are replaced with native oak species in accordance with the City’s Tree Technical Manual, supporting habitat value, ecological continuity and wildlife habitat. The project is consistent with Policies N-1.4, N-1.5, and N-1.6, the residence is sited more than 500 feet from Arastradero Creek, outside riparian corridors, and avoids direct disturbance to creek resources and special-status habitats. Project review ensures construction and operation would not adversely affect sensitive biological resources. The project aligns with Policies N-1.8 and N-1.9 addressing the natural character of the foothills. The residence is located away from ridgelines and hilltops, oriented parallel to Laurel Glen Drive, and set back approximately 74 feet from the roadway. Building massing follows natural topography, grading is minimized, and access is provided via a rural-style permeable concrete and concrete driveway, reducing visual prominence and impervious surface area. Exterior materials and colors are subdued, exterior lighting is low-intensity and shielded, and existing vegetation, including protected trees, is retained to the extent feasible to ensure the project visually blends with its surroundings.

BACKGROUND. The City Council of the City of Palo Alto (“City Council”) finds, determines, and declares as follows: A. On January 8, 2025, Daniel Hruby, on behalf of VRchitects, Inc, applied for a Site and Design application to allow construction of a new 6,581-square-foot single-family residence and associated site improvements on a vacant 4.23-acre site. (“The Project”). B. Staff has determined that the proposed project is in compliance with the applicable Open Space development standards per Palo Alto Municipal Code (PAMC) Section 18.28.050. C. Following staff review, the Planning and Transportation Commission (Commission) reviewed the project design on February 11, 2026, and recommended ___________. D. On ____________, the City Council reviewed the project design. After hearing public testimony, the Council voted to approve the project subject to the conditions set forth in Section 4 of this Record of Land Use Action. SECTION 2. ENVIRONMENTAL REVIEW. In conformance with the California Environmental Quality Act (CEQA) Class 3 Categorical Exemption Pursuant to Section 15303, the Project is exempt from CEQA and none of the Exceptions to the Categorical Exemption Listed in CEQA Guidelines Section 15300.2 apply to the proposed project. SECTION 3. SITE AND DESIGN OBJECTIVES. The design and architecture of the proposed improvements, as conditioned, complies with the Site and Design Objectives, as required per PAMC Section 18.30(G).060. A. Objective (a): To ensure construction and operation of the use in a manner that will be orderly, harmonious, and compatible with existing or potential uses of adjoining or nearby sites. The proposed use is a single-family house in the Open Space (OS) zoning district, on a vacant lot adjacent to other existing single-family residential uses. The proposed construction, as conditioned, complies with the development standards of the OS District in addition to all Municipal Code requirements that help to maintain order and compatibility with surrounding uses, including, but not limited to, noise, parking, and fire safety regulations. Therefore, construction and operation of the use will be orderly, harmonious, and Item 3 Attachment C - Draft Record of Land Use Action     Packet Pg. 38     Page 2 compatible with existing or potential uses of adjoining or nearby sites. 1. The development should not be visually intrusive from public roadways and public parklands. As much as possible, development should be sited so it is hidden from view. Item 3 Attachment C - Draft Record of Land Use Action     Packet Pg. 39     Page 3 2. Development should be located away from hilltops and designed to not extend above the nearest ridgeline. The residence is located on a lower portion of the property, away from hilltops, and does not extend above the nearest ridgeline. The design follows the natural slope and, together with existing trees, ensures the building remains visually subordinate to the surrounding topography. 3. Site and structure design should take into consideration impacts on privacy and views of neighboring properties. The residence is designed and sited to minimize impacts on neighboring privacy and preserve views. Upper-level windows and decks are oriented away from adjacent homes, and existing trees and landscaping provide additional screening to reduce potential privacy or view impacts. 4. Development should be clustered, or closely grouped, in relation to the area surrounding it to make it less conspicuous, minimize access roads, and reduce fragmentation of natural habitats. The proposed development is proposed for a small section of the overall 4.23-acre site. One driveway/access road will provide access to the unit located near existing developments on adjacent buildings. The project does not propose multiple buildings and is concentrated to a single area on the site, avoiding densely vegetated areas. 5. Built forms and landscape forms should mimic the natural topography. Building lines should follow the lines of the terrain, and trees and bushes should appear natural from a distance. The residence and hardscape are designed to follow the natural slope of the site, with building lines stepped to align with existing contours. Retained and new trees and landscaping are placed to appear natural from a distance, integrating the development with the surrounding topography. 6. Existing trees with a circumference of 37.5 inches, measured 4.5 feet above the ground level, should be preserved and integrated into the site design. Existing vegetation should be retained as much as possible. The project preserves existing trees wherever feasible, including all trees with a circumference of 37.5 inches or greater that are not proposed for removal to allow for construction on the most suitable development area of the site. The arborist report surveyed 63 trees within the project vicinity. A total of 15 trees are proposed for removal, including 14 protected Coast Live Oaks and Blue Oaks. To offset these removals, 28 replacement Coast Live Oak and Blue Oak trees will be planted on site. All remaining trees within the project area will be protected during construction with tree protection fencing in accordance with City standards, maintaining the natural character of the property. 7. Cut is encouraged when it is necessary for geotechnical stability and to enable the development to blend into the natural topography. Fill is generally discouraged and should never be distributed within the driplines of existing trees. Locate development to minimize the need for grading. The project minimizes grading by following the site’s natural slope and avoiding unnecessary cut or fill. Limited grading is proposed only where needed for geotechnical stability, and no fill will be placed within the driplines of existing trees, allowing the development to blend with the Item 3 Attachment C - Draft Record of Land Use Action     Packet Pg. 40     Page 4 natural topography. 8. To reduce the need for cut and fill and to reduce potential runoff, large, flat expanses of impervious surfaces should be avoided. The project minimizes impervious surfaces by limiting hardscape to essential areas and retaining natural site contours. The design avoids large, flat expanses, reducing grading and potential stormwater runoff while preserving the site’s natural drainage patterns. 9. Buildings should use natural materials and earth tone or subdued colors. The residence uses natural materials, including wood siding and decking, and incorporates earth-toned, subdued colors. These design choices ensure the building blends with the surrounding landscape and minimizes visual impact. 10. Landscaping should be native species that require little or no irrigation. Immediately adjacent to structures, fire retardant plants should be used as a fire prevention technique. Landscaping will consist primarily of native, drought-tolerant species requiring minimal irrigation. No new landscaping is proposed immediately adjacent to the home to reduce wildfire risk. 11. Exterior lighting should be low-intensity and shielded from view so it is not directly visible from off-site. All exterior lighting will be low-intensity, directed downward, and shielded to prevent visibility from off-site. This approach minimizes light spill and preserves the natural character of the surrounding Open Space. 12. Access roads should be of a rural rather than urban character. (Standard curb, gutter, and concrete sidewalk are usually inconsistent with the foothills environment). The new access driveway is designed to follow the natural topography and minimize grading. Permeable pavers and concrete are used to maintain a rural character, reduce runoff, and blend the driveway with the surrounding foothills environment. 13. For development in unincorporated areas, ground coverage should be in general conformance with Palo Alto's Open Space District regulations. The project is within Palo Alto City limits, not in an unincorporated area. SECTION 5. Conditions of Approval. PLANNING DIVISION 1. CONFORMANCE WITH PLANS.

The project consists of a single-family residence designed to preserve the site’s natural hillside character, minimize environmental disturbance, and integrate with the surrounding landscape. Below is a summary demonstrating the project’s consistency with the Palo Alto Comprehensive Plan and the Open Space Development Criteria adopted on October 20, 1986 . 1. Consistency with the Palo Alto Comprehensive Plan The proposed development is consistent with the following goals and policies from the Comprehensive Plan: Land Use Policy L-6.4 (Protection of Open Space Areas): The project is sited and designed to preserve the open hillside setting. In conjunction with the City Arborist and the Fire Marshall, 15 trees (14 protected and 1 unprotected) have been designated as eligible for removal for the building and for thinning cluster trees within 30’ of the building, and the structure is positioned to work with the existing slope to minimize grading and maximize views. Natural Environment Policy N-1.2 (Environmental Stewardship): Native, fire resistant and drought-tolerant landscaping is incorporated to enhance ecological health and reduce water consumption. 60 new replacement trees are proposed in compliance with the Palo Alto tree technical manual. Replacement tree species include Coastal Live Oak, Blue Oak and Valley Oak, all native to the local environment. Design & Built Environment Goal L-6 (Context-Sensitive Design): The home maintains a low profile from the public right-of-way, uses earth-toned materials, and is stepped with the slope, blending with the natural terrain. ATTACHMENT DItem 3 Attachment D - Applicant's Project Description     Packet Pg. 48     908 Industrial Ave, Palo Alto CA 94303 | (833) 262-2208 | dan@spacial.io | www.spacial.io Page | 2  Mobility Goal T-5 (Minimizing Impacts): The driveway utilizes permeable concrete to reduce runoA, and parking is accommodated entirely on-site with no additional demand on local streets. 2. Compliance with the 10 Open Space Development Criteria 1. Preservation of Natural Character: The design minimizes grading by following the natural slope. The lower level is terraced to preserve topography, and mature trees are preserved. Minimal grading outside of the building envelope has been proposed to maintain the natural contours of the site. 2. Views and Vistas: The structure is sited downslope from the street, protecting public view corridors. Upper decks and glazing maximize private enjoyment of views without creating massing impacts from public vantage points. Story poles have been installed on the site to verify and ensure that the building will not disturb the views and vistas of the public and the neighbors. 3. Environmental Quality: Permeable surfaces, drought-resistant planting, and rooftop solar panels are included. Erosion control measures will be implemented during construction in order to prevent any contamination. 4. Use Compatibility: The proposed single-family residential use is consistent with the passive, low-density intent of the OS zone. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 49     908 Industrial Ave, Palo Alto CA 94303 | (833) 262-2208 | dan@spacial.io | www.spacial.io Page | 3 5. Access and Circulation: Site access is via a single, existing driveway. Circulation is limited and unobtrusive. The permeable concrete driveway provides both function and environmental benefit. 6. Facility Design: The architecture is modern and modest in scale, with low pitched roofs and earth-tone materials that recede visually into the landscape. 7. Vegetation and Landscaping: Landscaping uses fire resistant, native species to preserve habitat value and minimize maintenance. No invasive species are proposed. 60 new replacement trees are proposed, in compliance with the Palo Alto tree technical manual. Replacement tree species include Coastal Live Oak, Blue Oak and Valley Oak, all native to the local environment. 8. Public Benefit: While this is a private residence, the design preserves the open character of the land, enhances natural resource protection, and avoids adverse public impacts. 9. Maintenance and Management: As a private residence, all maintenance is the responsibility of the homeowner. Long-term landscape and site maintenance will ensure continued preservation of site character. 10. Mitigation: All development impacts have been minimized through sensitive design and site planning. A construction management plan will mitigate temporary construction e Aects.

This property is considered an oak woodland, as it is dominated by native oak species such as Coast Live Oak (Quercus agrifolia), Valley Oak (Quercus lobata), and Blue Oak (Quercus douglasii). Survey Methods: The tree survey and inventory were conducted by ISA certified arborist W. M. Smith (Certification #WE-13625A), with a focus on assessing all trees with a single main stem diameter at breast height (DBH) of 5 inches or more, or co-dominant stems with a combined DBH of at least 6 inches. This survey included all trees located on the specified parcel, within 100 feet of the proposed development. It was determined that none of the trees in this survey are classified as heritage trees under the City of Palo Alto’s guidelines, nor are they considered orchard trees cultivated for commercial purposes. This assessment provides a comprehensive overview of each tree’s current health, structural condition, and potential impact within the context of the proposed site development. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 54     The following data was collected for each tree: •Trunk Diameter: Measured at 54 inches above grade (DBH). •Tree Species: Identified based on observed characteristics. •Tree Height: Approximate measurements taken visually. •Canopy Spread: Approximate measurements taken visually. •General Condition: Based on a visual assessment - no coring, lab testing, or aerial inspection were employed. Tree Condition and Structure: A visual assessment of health and structure were used to assign a general condition rating for each tree. The evaluation of the trees surveyed in this report was limited to a visual inspection of accessible parts without dissection, excavation, probing, or coring. There is no guarantee that additional problems or defects in the trees may not arise in the future. Refer to the following scale for general condition: Good: 75%-100% healthy foliage, free of major defects, good form and function for the location. Fair: 35-75% healthy foliage, moderate defects that may compromise the function or form of the tree overtime if left un-treated. Poor: Less than 35% of healthy foliage and significant defects resulting in a low life expectancy. This assessment includes 63 trees, with the majority rated in Fair condition due to both health and structural challenges from lack of proper maintenance. Trees in this category generally exhibit some vigor in foliage and growth, though they have minor to moderate defects that impact their structural stability and long term health, such as co-dominant stems, moderate leans, the presence of included bark, or decay cavities. These moderate defects contribute to a reduced suitability for preservation under current site conditions. A smaller subset of trees has been classified in Poor condition, showing significant decline in health and structural integrity, often due to past damage, disease, or inadequate previous maintenance. Only a few trees have received a Good condition rating, distinguished by healthy, dense foliage and an absence of significant structural or health Item 3 Attachment D - Applicant's Project Description     Packet Pg. 55     defects. These trees represent the best preservation candidates, as they are expected to continue thriving with minimal intervention. The findings suggest that, while a number of trees contribute positively to the site, the majority will require management or removal due to their compromised condition. Tree Structure: Good: Minor structural flaws that may be corrected through pruning. Tree has an upright trunk and a single trunk tapering to a single leader at the top. Most scaffold branches are smaller than the leader, attached to the trunk at angles approaching 45 degrees and are spaced apart on the trunk both vertically and radially. Structure does not contain included bark {bark inside the juncture of multiple trunks). No sign of previous branch failures. Foliage is evenly distributed on the limbs. Symmetrical or mostly symmetrical canopy. Fair: Some structural flaws not correctable through pruning. Tree may have more than one trunk or leader, trunk may have a slight lean. Scaffold branches may be attached at angles less than 30 degrees and/or may be crowded on the trunk. Structure may have included bark, previous branch failures or end-heavy limbs. Some asymmetry in the canopy. Poor: Significant structural flaws not correctable through pruning. Significant dead wood or decay. More than one trunk or leader and/or branches crowded together on the trunk. Significantly end-heavy limbs may be present. Structure may contain significant included bark, previous branch failures and/or asymmetry. Precipitous lean may be present. Tree is likely to be hazardous. Inventory Results: Moki Smith Arborist surveyed a total of 63 trees across the parcels that are included in the proposed development project. This tree inventory includes all of the significant trees that are located within 100 feet of the proposed development. All of the trees present within the parameters of this survey are considered indigenous species. The indigenous species includes forty blue oaks (Quercus douglasii), eighteen coast live oaks (Quercus agrifolia), and four valley oaks (Quercus lobata). Protected trees are noted in the inventory tree table. There are no fruit or orchard trees located on the parcel, and none of these trees are used for commercial purposes. Of the trees included in this report 55 are considered protected under Palo Alto City Ordinance. There are no invasive or non- indigenous trees located on the property within the parameters included in this report. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 56     Suitability for Preservation: In assessing the trees’ suitability for preservation, several factors were considered: 1.Health: Healthy trees are better equipped to tolerate development impacts, such as soil compaction and changes in moisture. 2.Structural Integrity: Trees with significant decay or structural defects increase the likelihood of failure, which can increase the possibility that the tree poses a threat or hazard, particularly in areas near people or property. 3.Species Response: Certain species, such as those accustomed to the native environment, are more tolerant of development impacts than non-native species which may require different environmental conditions to prosper ( such as increased irrigation). 4.Age and Longevity: Older trees may be less adaptable to development impacts and root damage/loss, while younger trees have greater capacity for regeneration and adjustment. The suitability for preserving the 63 trees located on this development site in Palo Alto varies due to several factors. While 55 of these trees are considered protected, many of the trees have less preservation value due to structural and health issues. These defects include multiple co-dominant stems that emerge from low or below-ground main crotches, and the presence of included bark, which increases structural risk as the trees mature. This is compounded by poor structure, with many trees leaning toward light sources, which predisposes them to failure under extreme weather conditions such as high winds or heavy rainfall. Additionally, several of the oaks exhibit moderate decay on their main stems, a result of unaddressed damage from lost major limbs or fungal diseases infecting tissue of the main stem. To ensure the longevity and structural integrity of the oak trees slated for preservation, targeted pruning should be undertaken. This includes the removal of large deadwood to minimize potential hazards and promote tree health. Structural pruning is recommended to enhance canopy balance, reduce stress on weak or vulnerable branches, and lower the risk of structural failure, particularly under adverse weather conditions. These efforts not only improve safety but also support the tree's ability to thrive in the landscape while Item 3 Attachment D - Applicant's Project Description     Packet Pg. 57     maintaining its ecological and aesthetic value. Proper pruning should adhere to ANSI A300 standards to minimize damage and promote optimal healing of pruning wounds. Some of the oak trees on the site exhibit signs of fungal diseases affecting their foliage and stems, which could pose a risk to their overall health if not addressed. To mitigate the spread of these fungal pathogens, a proactive treatment plan is recommended, including the application of appropriate fungicides as determined by further diagnostic analysis. Additionally, these trees should be fertilized to optimize soil health and enhance the trees' vigor, increasing their natural resistance to infections and diseases. Improving cultural practices such as proper irrigation and mulch application can further reduce stress on the trees and support their recovery. These measures should be implemented under the guidance of a certified arborist to ensure their effectiveness and adherence to best practices. The majority of the trees located on the subject property are native Coast live oaks (Quercus agrifolia), Blue oaks (Quercus Douglasii), and Valley oaks (Quercus lobata) which show a high potential for successful preservation, due to their native status and natural adaptation to local conditions. These trees are likely to thrive long-term on this site if proper maintenance and cultural care are preformed. Protected Trees: Palo Alto Tree Ordinance 8.10.010 Purpose. The purpose of this chapter is to protect specified trees located on private property within the city, and establish standards for removal, maintenance, and planting of trees and landscaping. In establishing these procedures and standards, the city recognizes that trees and landscaping are an essential part of the city's infrastructure. Their benefits include promoting the health, safety, welfare, and quality of life of the residents of the city; addressing climate change by sequestering carbon and providing a cooling effect; reducing air, water, and noise pollution; preventing soil erosion and stormwater runoff; providing wildlife habitat; and enhancing the aesthetic environment. It is the city's intent to encourage both the preservation of trees and the proactive incorporation of trees and their benefits within development. “Protected” tree includes the three species that were already protected as well as additional native tree species and all trees above specified minimum diameters, except high water users and invasive species. [§8.10.020(l)] Item 3 Attachment D - Applicant's Project Description     Packet Pg. 58     8.10.050 Removal of protected trees. It shall be a violation of this chapter for anyone to remove or cause to be removed a protected tree, except pursuant to a protected tree removal permit issued under Section 8.10.140 consistent with the following: (a)In the absence of proposed development: (1)A protected tree shall not be removed unless the urban forester grants a protected tree removal permit, or on parcels zoned other than single-family (R-1) or low density residential (RE, R-2, or RMD), the director of planning and development services authorizes the removal through staff level architectural review pursuant to Section 18.76.020(b)(3), having determined, on the basis of a tree report prepared by a designated arborist and other relevant information, that treatments or corrective practices are not feasible, and that the tree should be removed because any of the following apply: (i)It is dead, is hazardous, or constitutes a public nuisance under Section 8.04.050 of this code. (ii)It is a detriment to or is crowding an adjacent protected tree. (iii)It is at risk for retrenchment or other tree decline coping processes or does not conform with right tree in the right place principles. (iv)It is impacting the foundation or eaves of a residence, or any covered parking required under Title 18 of this code. (2)In the event a protected tree is removed pursuant to a protected tree removal permit granted under this subsection (a), a temporary moratorium on development of the subject property may be issued by the urban forester for up to twenty-four months or by, the director of planning and development services, in consultation with the urban forester, for up to thirty-six months, from the date the tree removal occurred. Completion of required mitigation measures included in the tree removal permit does not remove or shorten any such moratorium. A moratorium may be terminated early with approval of the urban forester or director of planning, and development services, as applicable, and may require additional mitigation measures. Mitigation measures included in the protected tree removal permit and any additional mitigation measures required to shorten a moratorium shall be imposed as a condition of any subsequent permits for development on the subject property.

(2)Retention of one or more trees would result in reduction of the otherwise-permissible buildable area of the lot by more than twenty-five percent, and there is no financially feasible design alternative that would allow for preservation of the tree(s). For the purposes of this subsection (a)(2), a financially feasible design alternative means a design alternative that preserves the tree(s) and would not increase the project cost by more than twice the reproduction cost of the tree(s) or ten percent of the given project valuation, whichever is greater. All tree protection zones impacting buildable area are included in the reduction of buildable area calculation. (3)The tree could be removed due to the conditions listed in Section 8.10.050(a)(1)(i), (ii), or (iii) and treatments or corrective practices are not feasible. (c)In the case of development involving a proposed subdivision of land into two or more parcels, a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that either of the following apply: (1)Removal is unavoidable due to restricted access to the property or deemed necessary to repair a geologic hazard (landslide, repairs, etc.), in which case only the protected tree or trees necessary to allow access to the property or repair the geologic hazard may be removed. (2)The tree could be removed due to the conditions listed in subsection (a)(1)(i), (ii), or (iii) and treatments or corrective practices are not feasible. (d)In the case of development requiring planning approval under Title 18, and not included under subsections (b) or (c), a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that any of the following apply: (1)Retention of one or more trees would result in reduction of the otherwise-permissible buildable area of the lot by more than twenty-five percent, and there is no financially feasible design alternative that would permit preservation of the tree(s), where financially feasible means an alternative that preserves the tree(s) unless retaining the tree(s) would increase project cost by more than twice the reproduction cost of the tree or ten percent of the given project valuation, whichever is greater. All tree protection zones impacting buildable area are included in the reduction of buildable area calculation. (2)The tree should be removed because it is dead, hazardous, or constitutes a public nuisance under Section 8.04.050. In such cases, the tree protection zone of the removed tree, or an equivalent area on the site, shall be preserved for mitigation purposes from development of any structure. (3)Discretionary development review determines that the final project follows right tree in the right place principles and would result in a net tree canopy increase on the property within fifteen years, and replacement of trees, shrubs, and plants either: (i)Is consistent with Urban Forest Master Plan Goal 2: "Re-generated native woodland and riparian landscapes as the key ecological basis of the urban forest with focus on native species and habitat," or (ii)Uses climate adaptive, drought tolerant species. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 60     (e)In any circumstance other than those described in subsections (a), (b), (c), or (d), a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that the tree is dead, is hazardous, or constitutes a public nuisance under Section 8.04.050. 8.10.055 Tree replacement. (a)In the event a protected tree is removed pursuant to Section 8.10.050(a)(1)(i), mitigation for the removed tree, replacement tree ratio, in lieu fees, or a combination thereof shall be determined by the urban forester, based on factors including but not limited to the species, size, location, and specific reason for removal of the protected tree, in accordance with the standards and specifications in the Tree and Landscape Technical Manual. (b)In the event a protected tree is removed pursuant to Section 8.10.050 (a)(1)(ii), (iii), or (iv), (b), (c), (d), or (e), the tree removed shall be replaced in accordance with the standards and specifications in the Tree and Landscape Technical Manual, including but not limited to prioritization of locally native species, satisfaction of right tree in the right place principles, and incorporation of a secondary goal of net tree canopy increase on the property within fifteen years. The urban forester shall approve the number, species, size, and location of replacement trees. Indigenous species: The following trees are considered indigenous: Coast live oak, Valley oak, Coast redwood, Big leaf maple, Blue oak, California black oak, California incense cedar, and Blue oak. Potential Impacts: The proposed development will necessitate the removal of several oak trees located directly within the construction footprint to accommodate the property structures. For the trees designated for retention, it is critical to implement protective measures to minimize construction-related impacts. Tree protective fencing must be installed around the drip- line of each retained tree to safeguard the main stems, canopies, and critical root zones from damage caused by heavy machinery and soil compaction. The fencing should be robust, highly visible, and remain in place for the duration of the project.

Item 3 Attachment D - Applicant's Project Description     Packet Pg. 72     Site Map Item 3 Attachment D - Applicant's Project Description     Packet Pg. 73     Tree Protection Measures for construction •Avoid root damage through grading, trenching, compaction, etc., at least within an area 1.5 times the ‘drip-line’ area of trees. Where root damage cannot be avoided, roots encountered (over 1" diameter) should be exposed approximately 12" beyond the area to be disturbed (towards tree stem), by hand excavation, or with specialized hydraulic or pneumatic equipment, cut cleanly with hand pruners or power saw, and immediately back-filled with soil. Avoid tearing, or otherwise disturbing that portion of the root(s) to remain. •Construct a temporary fence as far from the tree stem (trunk) as possible, and at least as far as the drip-line of the tree. This fencing should completely surround the tree. Post no parking or storage signs outside / on fencing. Do not attach posting to the main-stem of the tree. •Do not allow vehicles, equipment, pedestrian traffic; building materials or debris storage; or disposal of toxic or other materials inside of the fenced off area. •Trees that will be impacted by construction may benefit from fertilization, ideally performed in the fall, and preferably prior to any construction activities. •Mulch rooting area with an acidic, organic compost or mulch. •Arrange for periodic (Biannual/Quarterly) inspection of tree's condition, and treatment of damaging conditions (insects, diseases, nutrient deficiencies, etc.) as they occur, or as appropriate. •Individual trees likely to suffer significant impacts may require specific, more extensive efforts and/or a more detailed specification than those contained within these general guidelines. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 74     Protective tree fencing shall specify the following: (1)Size and materials. Six (6) foot high chain link fencing, mounted on two-inch diameter galvanized iron posts, shall be driven into the ground to a depth of at least two (2) feet at no more than 10-foot spacing. For paving area that will not be demolished and when stipulated in a tree preservation plan, posts may be supported by a concrete base. (2)Area type to be fenced. Type I: Enclosure with chain link fencing of either the entire drip- line area or at the tree protection zone (TPZ), when specified by a certified or consulting arborist. Type II: Enclosure for street trees located in a planter strip: chain link fence around the entire planter strip to the outer branches. Type III: Protection for a tree located in a small planter cutout only (such as downtown): orange plastic fencing shall be wrapped around the trunk from the ground to the first branch with 2-inch wooden boards bound securely on the outside. Caution shall be used to avoid damaging any bark or branches. (3)Duration of Type I, II, III fencing. Fencing shall be erected before demolition, grading or construction permits are issued and remain in place until the work is completed. Contractor shall Page 14 first obtain the approval of the project arborist on record prior to removing a tree protection fence. (4)Warning sign. Each tree fence shall have prominently displayed an 8.5 x 11-inch sign stating: "Warning—Tree Protection Zone-this fence shall not be removed and is subject to penalty according to Town Code 29.10.1025” (5)Prior to the commencement of construction, install the fence at the drip-line, around any tree and/or vegetation to be retained which could be affected by the construction and prohibit any storage of construction materials or other materials, equipment cleaning, or parking of vehicles within the TPZ. The drip-line shall not be altered in any way so as to increase the encroachment of the construction. (6)Prohibit all construction activities within the TPZ, including but not limited to: excavation, grading, drainage and leveling within the drip-line of the tree unless approved by the Director. (7)Prohibit disposal or depositing of oil, gasoline, chemicals or other harmful materials within the drip-line of or in drainage channels, swales or areas that may lead to the drip-line of a protected tree. (8)Prohibit the attachment of wires, signs or ropes to any protected tree. (9)Design utility services and irrigation lines to be located outside of the drip-line when feasible. (10)Retain the services of a certified or consulting arborist who shall serve as the project arborist for periodic monitoring of the project site and the health of those trees to be preserved. The project arborist shall be present whenever activities occur which may pose a potential threat to the health of the trees to be preserved and shall document all site visits. (11)The Director and project arborist shall be notified of any damage that occurs to a protected tree during construction so that proper treatment may be administered. Item 3 Attachment D - Applicant's Project Description     Packet Pg. 75     Tree Removal Plan Palo Alto Tree Removal and Replacement Ordinances 8.10.050 Removal of protected trees. It shall be a violation of this chapter for anyone to remove or cause to be removed a protected tree, except pursuant to a protected tree removal permit issued under Section 8.10.140 consistent with the following: (a)In the absence of proposed development: (1)A protected tree shall not be removed unless the urban forester grants a protected tree removal permit, or on parcels zoned other than single-family (R-1) or low density residential (RE, R-2, or RMD), the director of planning and development services authorizes the removal through staff level architectural review pursuant to Section 18.76.020(b)(3), having determined, on the basis of a tree report prepared by a designated arborist and other relevant information, that treatments or corrective practices are not feasible, and that the tree should be removed because any of the following apply: (i)It is dead, is hazardous, or constitutes a public nuisance under Section 8.04.050 of this code. (ii)It is a detriment to or is crowding an adjacent protected tree. (iii)It is at risk for retrenchment or other tree decline coping processes or does not conform with right tree in the right place principles. (iv)It is impacting the foundation or eaves of a residence, or any covered parking required under Title 18 of this code. (2)In the event a protected tree is removed pursuant to a protected tree removal permit granted under this subsection (a), a temporary moratorium on development of the subject property may be issued by the urban forester for up to twenty-four months or by, the director of planning and development services, in consultation with the urban forester, for up to thirty-six months, from the date the tree removal occurred. Completion of required mitigation measures included in the tree removal permit does not remove or shorten any such moratorium. A moratorium may be terminated early with approval of the urban forester or director of planning, and development services, as applicable, and may require additional mitigation measures. Mitigation measures included in the protected tree removal permit and any additional mitigation measures required to shorten a moratorium shall be imposed as a condition of any subsequent permits for development on the subject property. (b)In the case of any development on a single-family (R-1) or low density (RE, R-2, or RMD) residential zoned parcel, other than in connection with a subdivision, a protected tree shall not be removed unless the tree is proposed for removal to accommodate an ADU constructed pursuant to Section 18.09.030, or because removal is necessary to allow an ADU constructed pursuant to Section 18.09.040 to achieve the minimum standards set forth in state law, or it is determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that any of the following apply: (1)The tree is so close to the proposed development that construction would result in the death of the tree, and there is no financially feasible design alternative that would permit preservation of the tree, where financially feasible means an alternative that preserves the tree unless retaining the tree would increase project cost by more than twice the reproduction cost of the tree or ten percent of the given project valuation, whichever is greater. (2)Retention of one or more trees would result in reduction of the otherwise-permissible buildable area of the lot by more than twenty-five percent, and there is no financially feasible design alternative that Item 3 Attachment D - Applicant's Project Description     Packet Pg. 76     would allow for preservation of the tree(s). For the purposes of this subsection (a)(2), a financially feasible design alternative means a design alternative that preserves the tree(s) and would not increase the project cost by more than twice the reproduction cost of the tree(s) or ten percent of the given project valuation, whichever is greater. All tree protection zones impacting buildable area are included in the reduction of buildable area calculation. (3)The tree could be removed due to the conditions listed in Section 8.10.050(a)(1)(i), (ii), or (iii) and treatments or corrective practices are not feasible. (c)In the case of development involving a proposed subdivision of land into two or more parcels, a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that either of the following apply: (1)Removal is unavoidable due to restricted access to the property or deemed necessary to repair a geologic hazard (landslide, repairs, etc.), in which case only the protected tree or trees necessary to allow access to the property or repair the geologic hazard may be removed. (2)The tree could be removed due to the conditions listed in subsection (a)(1)(i), (ii), or (iii) and treatments or corrective practices are not feasible. (d)In the case of development requiring planning approval under Title 18, and not included under subsections (b) or (c), a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that any of the following apply: (1)Retention of one or more trees would result in reduction of the otherwise-permissible buildable area of the lot by more than twenty-five percent, and there is no financially feasible design alternative that would permit preservation of the tree(s), where financially feasible means an alternative that preserves the tree(s) unless retaining the tree(s) would increase project cost by more than twice the reproduction cost of the tree or ten percent of the given project valuation, whichever is greater. All tree protection zones impacting buildable area are included in the reduction of buildable area calculation. (2)The tree should be removed because it is dead, hazardous, or constitutes a public nuisance under Section 8.04.050. In such cases, the tree protection zone of the removed tree, or an equivalent area on the site, shall be preserved for mitigation purposes from development of any structure. (3)Discretionary development review determines that the final project follows right tree in the right place principles and would result in a net tree canopy increase on the property within fifteen years, and replacement of trees, shrubs, and plants either: (i)Is consistent with Urban Forest Master Plan Goal 2: "Re-generated native woodland and riparian landscapes as the key ecological basis of the urban forest with focus on native species and habitat," or (ii)Uses climate adaptive, drought tolerant species. (e)In any circumstance other than those described in subsections (a), (b), (c), or (d), a protected tree shall not be removed unless determined by the urban forester, on the basis of a tree report prepared by a designated arborist and other relevant information, that the tree is dead, is hazardous, or constitutes a public nuisance under Section 8.04.050.

PLEASE RETURN COMPLETED WORKSHEET TO THE DEPARTMENT OF PLANNING & DEVELOPMENT SERVICES, DEVELOPMENT CENTER, 285 HAMILTON AVENUE, 1ST FLOOR. A total of 15 oak trees will be removed due to fire department requirements on fire defensible area regulations. (Of these 14 trees are protected.) An on-site meeting was held on 06.12.2025 with representatives of the fire department (Karl Schneider) and the urban forestry division (Uriel Hernandez). A detailed arborist report and tree disclosure statement is attached to this form. The above indicated tree removal has been a consenus agreed by all stakeholders. Due to the large size of the required fire defense zone (30' form the footprint of the building) relocating the building will only result with more trees to be removed. The design has been optimized to remove the least amount of trees. Per Palo Alto requirements 60 new 24" box size replacement trees are proposed (coast live oak, blue oak and valley oak) outside of the fire defense area. A total of 63 trees are present on the site, (specie includes coast live oak and blue oak) During site observation no mammals were present. However squirrels raccoons, coyotes and skunks can be seen in the larger neighborhood. Migratory birds such as robbins and thrush may visit the neighborhood. Dragonflies and butterlies can pass through. Please note that these species are typical in the larger neighborhood throughout, but no evidence of their direct presence in the site was observed. Project site is located in the OS zoning district in a single family residential neighborhood. Both neighboring lots on the Laurel Glen Dr contains existing single family residences. The neighborhood is charaterized with similar scale single family use lots with existing one and two story residences. Farther away downwards to the east is the Palo Alto Hills Golf and Country Club. The opposite side of the Laurel Glen Dr is surrounded by The Pearson-Arastrado preserve in north-westerly direction downwards. Topographically, the Laurel Glen Dr itself is occupies the ridge. 01/30/2026Daniel Hruby Item 3 Attachment D - Applicant's Project Description     Packet Pg. 85     GSPublisherVersion 112.28.86.1 otlA olaP fo ytiC !nalP eht fo traP s’tI - noitcetorP eerT Make sure your crews and subs do the job right!Fenced enclosures around trees are essential to protect them by keeping the foliage canopy and branching structure clear from contact by equipment, materials, and activities,preserving roots and soil conditions in an intact and non-compacted state, and identifying the Tree Protection Zone (TPZ) in which no soil disturbance is permitted and activities are restricted,unless otherwise approved.An approved tree preservation report must be added to this sheet when project activity occurs within the TPZ of a rteted tree.For detailed information on Palo Alto's teted trees and tee protection during development, review the Citys Tree a asae Technical Manual (TTM) found at www.cityofpaloalto.org/trees 1-TteehS noitcurtsnI noitcetorP eerT laicepS otlA olaP fo ytiC Apply Tree Preset Report on sheet(s) T-2 he eed Use ddt “T” sheets as needed ---GNINRAW--- enoZnoitcetorPeerT This fencing shall not be removed without City Arborist approval (650-496-5953) Removal without permission is subject to a $500 fine per day* *Palo Alto Municipal Code Section 8.10.110 1-T Pr o j e c t Da t a All other tree-related reports shall be added to the space provided on this sheet,adding sheets as needed.

APN_______-_______-_________ Lot size (sq. ft.)________________ Title of Dwg. used to calculate revised impervious area_________________________ Dwg. Date____________________ Land Use (Circle one): Residential Commercial Industrial Roadway For residential uses Þ Number of living units (Circle one): 1 2 3 or more Project Type (Circle one): New Development Redevelopment Watershed (Circle one): San Francisquito Matadero Barron Adobe SF Bay (see attached watershed map) Purpose of Worksheet The City of Palo Alto is collecting information on impervious surfaces created by land development projects in order to meet the requirements of its Stormwater Discharge Permit, issued by the San Francisco Bay Regional Water Quality Control Board. In addition, this information is used to calculate the monthly Storm Drainage Fee for non -single -family residential properties (single -family residential properties are assessed a flat monthly Storm Drainage Fee). Every developed land parcel in the City of Palo Alto is assessed a monthly Storm Drainage Fee. The fee is based upon the relative contribution of storm water runoff from each parcel to the City’s storm drainage system. A parcel’s relative contribution of storm water runoff is based upon the amount of “impervious surface” on that parcel. “Impervious surface” means that part of a developed parcel that has been modified to reduce the land’s natural ability to absorb and hold rainfall. It includes hard surfaces which cause water to run off the surface in greater quantit ies or at an increased rate of flow from the flow that existed under natural conditions prior to development. For example, common impervious surfaces include, but are not limited to, rooftops, walkways, patios, courtyards, driveways, parking lots, storage areas, concrete or asphalt paving, gravel roads, or any cleared, graded, graveled, paved, or compacted surfaces, or other surfaces which similarly impede the natural infiltration of surface water into the soil.
