SITE DATA Land Use Designation: Services and Manufacturing Zone: Service Commercial Zone with Planned Development Overlay (C-S-PD) Site Area: Approximately 3.5 acres Environmental Status: Categorically exempt from environmental review under CEQA Guidelines Section 15332 (Class 32 – In-Fill Development Projects) 1.0 PROJECT DESCRIPTION San Luis Obispo Classical Academy (SLOCA, Applicant) has applied for a Tree Removal Application (TRA, TREE-0033-2025) to remove 20 existing trees and provide 45 compensatory tree plantings at 3450 Broad Street (Attachment A – SLOCA Tree Removal Application, Attachment C – SLOCA Arborist Report). The TRA is associated with the Applicant’s Moderate Development Review (ARCH-0672-2024), Planned Development Amendment (PDEV-0673-2024), and Conditional Use Permit (USE-0674-2024) applications to establish and operate a private school with daycare services (i.e., infant childcare through eighth grade), including various building and site improvements, at the existing development (Attachment B – SLOCA Project Plans). Proposed building improvements include (a) an approximate 4,300 square foot addition (i.e., enclose loading dock to accommodate gymnasium, second floor offices, and library mezzanine) to the existing approximate 50,800 square foot building (to result in an approximate 55,100 square foot building); (b) tenant improvements to create classrooms, offices, library, gymnasium, etc.; (c) façade upgrades, including new exterior colors and Meeting Date: 03/24/2025 Item Number: 4a Time Estimate: 30 minutes Page 9 of 65 Item 4a TREE-0033-2025 (ARCH-0672-2024, PDEV-0673-2024, USE-0674-2024) Tree Committee Report – March 24, 2025 finishes; and (d) establishment of a sign program. Proposed site improvements include (a) removal of the north parking lot and replacement with an outdoor field and various activity areas; (b) design revisions to the south parking lot to accommodate new access and circulation improvements; and (c) landscape upgrades, which include the 20 tree removals and 45 compensatory tree plantings. In addition to the Tree Committee’s (TC) review, the overall project scope requires a review and recommendation by the Architectural Review Commission (ARC) for the various proposed building and site improvements, and a final review and decision by the Planning Commission (PC) to allow the private school and daycare services along with all associated building and site improvements. The project is tentatively scheduled for the ARC’s review on Monday, April 7, 2025, and for the PC’s review and final decision on Wednesday, May 14, 2025. Tree Removals The project site includes a total of 40 trees, which consist primarily of Callery pear trees (Pyrus calleryana) with three (3) Australian willows (Geijera parviflora), three (3) coast live oaks (Quercus agrifolia), one (1) Western Sycamore (Platanus racemosa), and one (1) cut tree (currently a stump and may have been a plum tree) (Attachment B – Sheet L1.2A of Project Plans). To facilitate the project, the Applicant is requesting the removal of 20 trees as follows:  To accommodate a new outdoor field and various recreational a ctivity areas, nine (9) trees located in the north parking lot (identified as Trees #2 -6, 8, 30-31) would be removed; o Note – Tree #8 has been cut (may have previously been a plum tree), and its stump is to be removed as part of the project.  To accommodate new decks for outdoor classroom areas and a seating area, ten (10) trees located in the side yard along Sacramento Drive (identified as Trees #9- 16, 32, 36) would be removed; and  To accommodate a new parking design, one (1) tree located in the south parki ng lot (identified as Tree #37) would be removed. Compensatory Plantings As proposed, the project includes 45 compensatory plantings consisting of Chitalpas (Chitalpa tashkentensis), Brisbane box trees (Lophostemon confertus), coast live oaks (Quercus agrifolia), Engelmann oaks (Quercus engelmannii), island oaks (Quercus tomentella), water gum (Tristaniopsis laurina), and Chinese elms (Ulmus parvifolia) (Attachment B – Sheet L1.2C of Project Plans). These compensatory trees would (a) range from 24-inch to 60-inch box replacements; (b) be planted on the perimeter of the outdoor field, along Sacramento Drive, and throughout the south parking area; (c) be native or native-adjacent trees; and (d) result in larger and more visually prominent trees at maturity for a majority of the selected species. In addition, the 20 existing trees to remain would be protected during project construction. Page 10 of 65 Item 4a TREE-0033-2025 (ARCH-0672-2024, PDEV-0673-2024, USE-0674-2024) Tree Committee Report – March 24, 2025 2.0 COMMITTEE PURVIEW Per Section 12.24.090(F)(4) (Process for Tree Removals Related to Ministerial or Discretionary Property Development Permits), the TC is to review a TRA related to Planning Applications (i.e., Moderate Development Review, Planned Development Amendment, and Conditional Use Permit) that require final approval by the PC and provide a recommendation to the PC as the approving authority. The TC’s review and recommendation for the project would be based on consistency with the policies and standards set forth in San Luis Obispo Municipal Code (SLOMC) Chapter 12.24 (Tree Regulations). 3.0 TREE REGULATIONS Per SLOMC Chapter 12.24 (Tree Regulations), the purpose of the Tree Regulations is to establish a comprehensive program for installing, maintaining, and preserving trees within the City. This Chapter establishes policies, regulations, and specifications necessary to govern installation, maintenance, removal, and preservation of trees to beautify the city; purify the air; provide shade and wind protection; add environmental and economic value; and preserve trees with historic or unusual value. Criteria for Construction Related Tree Removal Recommendations Per SLOMC Section 12.24.090(F)(4), the TC shall review and make a recommendation on the tree removal request to the authorized approving authority (i.e., PC) based on the criteria set forth in SLOMC Section 12.24.090(G)(1-7):  Size of Tree – Per Subsection (G)(1), the scale of the tree shall be considered, as well as the size of the tree’s canopy. Larger, more visually prominent trees may have a higher preservation priority than smaller, less visually prominent trees. The trees proposed for removal are fairly small in scale, ranging from 3 to 11- inches in diameter at breast height (DBH), with limited to moderate canopy sizes.  Location of Tree on Private Property – Per Subsection (G)(2), the location of the tree on private property shall be considered. Trees located in a private rear yard, which are not highly visible from the public right-of-way, may have a lower preservation priority than trees with a high visual impact to the neighborhood . The locations of the trees proposed for removal are visible from the public right-of- way because they are primarily located in the north parking lot and side yard area along Sacramento Drive. However, these trees may carry a lower preservation priority because they do not have a high visual impact to the neighborhood based on their fairly small scales.  Species of Tree – Per Subsection (G)(3), native trees shall have a higher preservation priority than non-native trees. The pear trees proposed for removal are non-native. Page 11 of 65 Item 4a TREE-0033-2025 (ARCH-0672-2024, PDEV-0673-2024, USE-0674-2024) Tree Committee Report – March 24, 2025  Forestry Best Practice – Per Subsection (G)(4), the number of healthy trees that a given parcel of land will support shall be considered, and whether removal would enhance the health or survival of remaining tr ees. Applications that increase biodiversity of native trees and tree age distribution within a given area are preferred. Of the 20 trees to be removed, 13 are in poor condition, six (6) are in fair condition, and one (1) has been cut and is a stump. The remaining 20 trees would be protected on site. As proposed, the 45 compensatory trees would provide a range of young native and native-adjacent trees that would increase the biodiversity and tree age distribution of the project site. The majority of the species selected are expected to result in larger and more visually prominent trees at maturity.  Public Right-of-Way Obstruction or Displacement – Per Subsection (G)(5), street trees requested for removal due to obstruction of vision, access, mobility of public traffic or sidewalk infrastructure repair or replacement shall have a lower preservation priority when the tree species is known to have invasive root structure or other characteristics that increase the likelihood that damage is likely to reoccur if not authorized for removal. Trees adjacent to sidewalks with a high volume of pedestrian use with large vertical or slope displacements may have a lower preservation priority. The trees proposed for removal are not due to obstruction of vision, access, mobility of public traffic or sidewalk infrastructure repair or replacement but are requested to accommodate new site improvements for a proposed school use.  Compliance with Subsection J of This Section Regarding Compensatory Plantings – Per Subsection (G)(6), the approving authority may consider an application proposal to provide compensatory plantings in excess of required minimums in evaluating this criterion. Per Section 12.24.090(J) (Compensatory Tree Planting), onsite tree removals require a minimum of one (1) new tree for each tree authorized for removal (1:1 replacement ratio). As proposed, the 20 tree removals and 45 compensatory plantings would result in a replacement ratio of 2.25:1, which significantly exceeds the minimum 1:1 requirement. All compensatory plantings will range from 24-inch to 60-inch box, exceeding the minimum 15-gallon size requirement.  Heritage Trees – Per Subsection (G)(7), heritage trees have the highest preservation priority. None of the trees onsite, or proposed for removal, are designated as heritage trees.

Recommend findings of consistency with the Tree Regulations. An action recommending approval of the application based on consistency with the SLOMC Chapter 12.24 (Tree Regulations) will be forwarded to the Planning Commission for final action. This action may include recommendations for conditions to address consistency with the Tree Regulations. 2. Continue the review of the project to a certain, or uncertain, hearing date. An action continuing the application should include direction to the applicant and staff on pertinent issues. 3. Recommend findings of inconsistency with the Tree Regulations. An action recommending denial of the application should include findings that cite the basis for denial and should reference inconsistency with the General Plan, Tree Regulations, or other policy documents. 5.0 ATTACHMENTS A - SLOCA Tree Removal Application B - SLOCA Project Plans C - SLOCA Arborist Report Page 13 of 65 Page 14 of 65 ' ' '"# "! &&$%& % % TREE REMOVAL APPLICATION For all Non-Construction and Construction related tree removals Owner Name: Applicant Name: Address:Address: City:Zip:City:Zip: Phone:Phone: Email:Email: Address of Tree(s): Number of trees applying to remove: Tree Species: Reason for Removal: Is this removal a City Tree?YES NO DON’T KNOW Dog in yard?

This report was prepared for a total of forty (40) trees, located on the site at 3450 Broad Street as required by the City of Sa n Luis Obispo (Fig. 1). The owner of 3450 Broad Street in San Luis Obispo, California, is preparing to renovate the existing commercial building and perform capital improvements to the landscape . There are twenty (20) trees on the property to be protected during the project and twenty (20) will require removal. The trees that are to be preserved may be impacted by the proposed development. Specifically, a group of three (3) Quercus agrifolia. (Coast Live Oaks; Trees 28, 29 & 33) in the rear parking lot, a Platanus racimosa (California Sycamore; Tree 34), and various small Pyrus ssp. (Pear) and Geijera sp. (Australian Willow) located along the property frontage may be impacted by the renovation. To what extent cannot be specifically determined, but by implementing the following Tree Protection Plan, impacts may be mitigated to a degree that the trees will survive and thrive . No trees on neighboring properties will be subjected to potential impacts to the project. This document estimates the proposed impacts and provides mitigation. It also serves as a tree protection plan to avoid damage during the construction. Project Description The commercial structure is to be converted to a school and landscaping upgraded with sports facilities. Tree Inventory Site evaluation was conducted on January 24, 2025, to include all trees 3-inches diameter or greater measured at 4.5-feet above grade, located within or directly adjacent to the property. The field analysis was conducted to document the following: • Unique identifying tree number consistent with numbering shown on the tree site plan/map ; • Tree species; • Trunk diameter/ DBH; • Health and structural condition with brief description of relevant characteristics ; • Suitability for preservation based on existing conditions and reason for removal (when recommended); ATTACHMENT C Page 45 of 65 Page 4 of 23 During the site visits, a visual inspection of the Roots, Trunk, Scaffold (Large) Branches, Small Branches & Twigs as well as Foliage & Buds was conducted using the following health, structure, and form determinations: Scoring System: 1. Poor: Extreme problems, decay and/or structural defects present, potential for future removal 2. Fair: Minor to Major problems present; Problems treatable and/or correctable 3. Good: No apparent problems, tree is in overall good health and vigor Inventory Map Figure 1: the existing structure and trees at 3450 Broad Street with tree locations numbered 1 through 40. ATTACHMENT C Page 46 of 65 Page 5 of 23 Inventory Data Table 1: the tree information for the existing trees at 3450 Broad Street. ATTACHMENT C Page 47 of 65 Page 6 of 23 Site Description 3450 Broad Street is an occupied, single-level commercial property. The southern parking lot along the frontage contains many ornamental trees. There is a steep berm up to Sacramento Drive . The northern parking lot has several sitting areas and is bounded by a creek . Site Plan Review The landscape design plans A1.0-4.0, dated 12/20/24, showing the proposed building footprint and landscape upgrades were issued to me. Impacts to Trees The following are potential impacts to trees from the proposed construction activities: Trees 1, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 36, 38, 39, & 40 – The existing root zone and canopy footprint will be protected with tree protection fencing (see Size and Type of Fence section). Impacts are not likely to the critical root zone and pruning is not anticipated. Existing ground cover should be removed and replaced with mulch. Any work performed within proximity to these trees will need to be done so under the supervision of the Project Arborist. Trees 28, 28, & 33 – The existing root zone and canopy footprint will be protected with tree protection fencing (see Size and Type of Fence section). There may be impacts to the critical root zone with the construction of raised wood decks. Pruning may be needed (Fig. 3). Existing ground cover should be removed and replaced with mulch. Any work performed within proximity to these trees will need to be done so under the supervision of the Project Arborist. Trees 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 30, 31, 32, 35, & 37 – these trees will be removed based as will be close to footprint of the proposed construction. Tree 34 —I do not foresee any impacts to this tree from any proposed construction activities including grading, excavation for utility installation, retaining walls, drainage, landscaping, or any other aspects of the project so long as construction activities remain out of their tree protection zones Replacement Trees The proposed removals are proposed to be replaced with the following quantities, species, and sizes: Four (4) 24-inch box Angophora costata (Sydney Red Gum) Two (2) 24-inch box Chitalpa taskentensis (Chitalpa) Six (6) 36-inch box Quercus agrifolia (Coast Live Oak) Four (4) 60-inch box Quercus engelmannii (Engelman Oak) Fourteen (14) 24-inch box Quercus tomentella (Island Oak) ATTACHMENT C Page 48 of 65 Page 7 of 23 Ten (10) 24-inch box Tristaniopsis laurina (Swamp Myrtle) Two (2) 48-inch box Ulmus parvifolia (Chinese Elm) Tree Protection Guidelines The objective of this section is to reduce the negative impacts of construction on trees to a less than significant level. Trees vary in their ability to adapt to altered growing conditions, while mature trees have established stable biological systems in the preexisting physical environment. Disruption of this environment by construction activities interrupts the tree’s physiological processes, causing depletion of energy reserves and a decline in vigor. This sometime is exhibited as death. Typically, this reaction may develop several years or more after disruption. The tree protection regulations are intended to guide a construction project to ensure that appropriate practices will be implemented in the field to eliminate undesirable consequences that may result from uninformed or careless acts and preserve both tree s and property values. The following a required to be implemented along with the TPP: The project arborist or contractor shall verify, in writing, that all preconstruction conditions have been met (tree fencing, erosion control, pruning, etc.) The demolition, grading and underground contractors, construction superintendent and other pertinent personnel are required to meet with the project arborist at the site prior to beginning work to review procedures, tree protection measures and to establish haul routes, staging, areas, contacts, watering, etc. Tree Protection shall be erected around trees to be protected to achieve three primary goals: To keep the foliage crowns and branching structure of the trees to be preserved clear from contact by equipment, materials, and activities; Preserve roots intact and maintain proper soil conditions in a non -compacted state and; To identify the tree protection zone (TPZ) in which no soil disturbance is permitted, and activities are restricted. Tree Protection Zone (TPZ) Each tree to be preserved shall have a designated TPZ identifying the area sufficiently large enough to protect the tree and roots from disturbance. Activities prohibited within the TPZ include: Storage or parking vehicles, building materials, refuse, excavated spoils or dumping of poisonous materials on or around trees and roots. Poisonous materials include, but are not limited to, paint, petroleum products, concrete or stucco mix, dirty water or any other material which may be deleterious to tree health. The use of tree trunks as a winch support, anchorage, as a temporary power pole, signposts, or other similar function. ATTACHMENT C Page 49 of 65 Page 8 of 23 Cutting of tree roots by utility trenching, foundation digging, placement of curbs and trenches and other miscellaneous excavation without prior approval of the project arborist. Activities Allowed Activities allowed or required within the TPZ include: Mulching: During construction, wood chips shall be spread within the TPZ to a six (6) inch depth, leaving the trunk clear of mulch to help inadvertent compaction and moisture loss from occurring. The mulch may be removed if improvements or other landscaping is required. Mulch material shall be two (2) inch unpainted, untreated wood chip mulch or approved equal. Root Buffer: When areas under the tree canopy cannot be fenced, a temporary buffer is required and shall cover the root zone and remain in place at the specified thickness until final grading stage. Irrigation, aeration, fertilizing or other beneficial practices that have been specifically approved for use within the TPZ. Size and type of fence Trees shall be protected with the following specifications: Six (6)-foot-tall chain link fencing shall be installed around the landscaped dripline of the trees. Fence posts shall be 1.5 inches in diameter, driven 2 feet into the ground, at most 10 feet apart . Signage (in both English and Spanish) should be printed on an 11” x 17” yellow -colored paper and secured in a prominent location on each protection fence. Signage shall include the Project Arborist’s contact information. Fencing may only be moved to within the TPZ if authorized by the Project Arborist and City Arborist. The fence must remain at least 1.5 times the diameter of the tree from its trunk (i.e. The fence must remain at least 30 - inches from the trunk of a 20-inch tree). The builder may not move the fence without authorization from the Project Arborist or City Arborist. ATTACHMENT C Page 50 of 65 Page 9 of 23 Duration of Tree Protection Fencing Tree fencing shall be erected prior to demolition, grading or construction and remain in place until final inspection or under the direction of the Project Arborist. Tree protection fencing, if required to be moved, must be moved under the direction of the Project Arborist. All tree protection zones need to be clear of debris and construction materials and cleared of weeds regardless of if fencing is present or not. “Warning” Signage Warning signs a minimum of 8.5x11-inches shall be prominently displayed on each fence. The sign shall clearly state the following in both English and Spanish: ATTACHMENT C Page 51 of 65 Page 10 of 23 Pruning, Surgery& Removal Any pruning shall occur prior to construction, pruning to clear from structures, activities, building encroachment or may need to be strengthened by means of mechanical support (cabling) or surgery. Such pruning, surgery or the removal of trees shall adhere to the following standards: Pruning limitations: • Minimum Pruning: If the project arborist recommends that trees be pruned, and the type of pruning is left unspecified, the standard pruning shall consist of ‘crown cleaning’ as defined by ISA Pruning Guidelines. Trees shall be pruned to reduce hazards and develop a strong, safe framework. • Maximum Pruning: Maximum pruning should only occur in the rarest situation approved by the project arborist. No more than one-fourth (1/4) of the functioning leaf and stem area may be removed within one (1) calendar year of any tree, or removal of foliage to cause the unbalancing of the tree. It must be recognized that trees are individual in form and structure, and that pruning needs may not always fit strict rules. The project arborist shall assume all responsibility for special pruning practices that vary from the standards outlined in this TPP. Tree Workers: Pruning shall not be attempted by construction or contractor personnel but shall be performed by a qualified tree care specialist or certified tree worker. The Project Arborist shall provide a follow-up letter documenting the pruning has been completed to specification. Activities During Construction & Demolition Near Trees Soil disturbance or other injurious and detrimental activity within the TPZ is prohibited unless approved by the project arborist. If an injurious event inadvertently occurs, or soil disturbance has been specifically conditioned for project approval, then the following mitigation is required: Soil Compaction: If compaction of the soil occurs, it shall be mitigated as outlined in Soil Compaction Damage, and/or Soil Improvement. Grading Limitations within the Tree Protection Zone: • Grade changes outside of the TPZ shall not significantly alter drainage to the tree. • Grade changes within the TPZ are not permitted. • Grade changes under specifically approved circumstances shall not allow more than six (6) inches of fill soil added or allow more than four (4) inches of existing soil to be removed from natural grade unless mitigated. Trenching, Excavation & Equipment Use No trenching, excavation, and heavy equipment used is permitted for this project unless specifically approved by the Project Arborist. ATTACHMENT C Page 52 of 65 Page 11 of 23 Root Severance No cutting and removal of roots is permitted for this project unless specifically approved by the Project Arborist. Irrigation Program Irrigate to wet the soil within the TPZ to a depth of twenty -four to thirty (24-30) inches at least once a month, preferably twice a month. Ten (10) gallons per inch DBH is enough. Begin irrigating immediately prior to any construction activity. Alternatively, sub -surface irrigation may be used at regular specified intervals by injecting on approximate three (3) foot centers, ten (10) gallons of water per inch trunk diameter within the TPZ. Duration shall be until project completion plus monthly until se asonal rainfall totals at least eight (8) inches of rain, unless specified otherwise by the project arborist. Damage to Trees - Reporting Any damage or injury to trees shall be reported within 6-hours to the project arborist and job superintendent or City Arborist so that mitigation can take place. Remedial action should be taken within 48-hours. All mechanical or chemical injury to branches, trunk or to roots over two (2) inches in diameter shall be reported in the monthly inspection report. In the event of injury, the following mitigation and damage control measures shall apply: Root injury: If trenches are cut and tree roots two (2) inches or larger are encountered they must be cleanly cut back to a sound wood lateral root. The end of the root shall be covered with either a plastic bag and secured with tape or rubber band or be coated with latex paint. All exposed root areas within the TPZ shall be backfilled or covered within one (1) hour. Exposed roots may be kept from drying out by temporarily covering the roots and draping layered burlap or carpeting over the upper three (3) feet of trench walls. The materials must be kept wet until backfilled to reduce evaporation from the trench walls. Bark or trunk wounding: Current bark tracing and treatment methods shall be performed by a qualified tree care specialist within two (2) days. Scaffold branch or leaf canopy injury: Remove broken or torn branches back to an appropriate branch capable of resuming terminal growth within five (5) days. If leaves are heat scorched from equipment exhaust pipes, consult the project arborist within six (6) hours. Any damage any tree’s canopy will need to be restoratively pruned effective immediately after the damage occurs and no later than 48 hours after the damage occurs. Any tree on-site protected by the City’s Municipal Code will require replacement according to its appraised value if it is damaged beyond repair because of construction activities. The Project Arborist shall provide a follow -up letter documenting the mitigation has been completed to specification. ATTACHMENT C Page 53 of 65 Page 12 of 23 Inspection Schedule The project arborist retained by the applicant shall conduct the following required inspections of the construction site: At least once every four (4) weeks; Monitor the effectiveness of the Tree Protection Plan; Provide recommendations for any necessary additional care or treatment; and Will be followed by monthly construction monitoring reports emailed directly to the City Arborist. The Project Arborist shall provide a follow-up letter documenting any mitigation has been completed to specification. A required final inspection is to be completed by the City Arborist at the end of the project. This is to be done before the tree protection fencing is taken down. Replacement trees should be planted at this time as well (before the tree protection fencing is taken down). Maintenance of Trees After Construction All trees to remain will need to be irrigated post-construction. Each tree should be inspected annually to monitor for disease or external stress and treated accordingly. Conclusion It is the nature of trees exposed to construction that some do not survive, and mortality cannot be predicted. If due care is exercised, all the trees on the project are expected to remain healthy and alive.
