The applicant would like to remove the trees and replace them with five (5) 15-gallon box trees onsite, including Trumpet Trees, Ginkgo or other species to the satisfaction of the City Arborist. 2.0 COMMITTEE PURVIEW The Tree Committee’s role is to review the removal request in accordance with the process set forth in San Luis Obispo Municipal Code (SLOMC) Chapter 12.24, specifically Section 12.24.090(E)(3). This code section utilizes the process set forth in subsection F(2), the relevant additional application requirements in subsection (D)(2) and the criteria set forth in subsection (G). Figure 2: Site of the proposed tree removal Page 10 of 35 Item 4a TREE-0805-2024 Tree Committee Report – February 24, 2025 3.0 TREE REGULATIONS Criteria for Convenience Tree Removal Applications. SLOMC §12.24.090 subsection (E)(3) requires review by the Tree Committee using the criteria set for in SLOMC §12.24.090(G). Applicable criteria are provided in italics below and followed by a description of the proposed tree removals as it relates to that criterion.  (G)(1). Size of Tree. 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 large and visually prominent in the neighborhood.  (G)(2). Location of Tree on Private Property. 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 tree proposed for removal is located in the backyard, but it is also highly visible from the public right of way.  (G)(3). Species of Tree. Native trees shall have a higher preservation priority than non-native trees. The trees proposed for removal are non-native.  (G)(4). Forestry Best Practice. 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 trees. Applications that increase biodive rsity of native trees and tree age distribution within a given area are preferred. The removal and replanting plan would increase the biodiversity of the urban forest and tree age distribution.  (G)(6). Compliance with Subsection J of This Section Regarding Compensatory Plantings. The approving authority may consider an application proposal to provide compensatory plantings in excess of required minimums in evaluating this criterion. The applicant is proposing to replant five (5) trees in place of two tree removals.  (G)(7). Heritage Trees. Heritage trees have the highest preservation priority. Trees are not heritage trees.

It is the owners, applicants’, and adjacent neighbors’ opinion that these trees are too large and burdensome for the current setting of being in a smaller sized rear yard within proximity to two residential houses (Primary resident address 2475 and the adjacent neighbor’s residence is 2493 Meadow St). Background: The property was purchased by the current owner in January 2016 and the current tenants have been living there since. Both trees were existing at the time of purchase and have continued to grow over the past 8 years. Pruning maintenance has been performed on both trees as well as installing a cable anchor to support a large section of Tree ID #2’s upper canopy. Even with this effort, limbs have fallen on the rear yard annually and the potential for large limbs to fall persists. The trees are located on a 2:1 sloped area of the yard that increases the potential that if these trees were to fall, they would land over the top of the 2475 residential structure. In addition, the trees both litter leaves and seeds year around that collect on the resident’s roof and yard space. To manage the litter from the trees the owners employ a landscape contractor to perform routine maintenance on the property twice a month. The oil from the leaves does not allow other landscaping to survive. The tenants also regularly remove leaf piles from the roof and rain gutters to prevent risk of property damage that would occur otherwise. Factoring regular clean up, pruning, and anchoring of these trees the cost has been upward of $10,000 in total over the past 8 years. The property contains 2 other large sycamore trees in the front yard that also pose maintenance challenges however the owners support keeping and caring for these trees. Lastly, the adjacent neighbors (2445 Meadow St and 497 Woodbridge St) rear yards have 5 redwood trees that are large and growing. This information is intended to convey that there is substantial other large trees in close proximity to the 2 requested to be reomved. Conclusion: The owner and tenants would request the city grant a tree removal permit due to the justification provided in this letter and application. The size and scale of these trees is a risk to both dwellings if/when limbs and/or the entire trees were to fall. The owner and applicant have made significant efforts to manage and maintain the trees over the past 8 years. However, the burden and cost of managing these trees has become overwhelming and no longer feels sustainable. We look forward to working together to come to a resolution. Please reach out if there are any questions related to processing this application and request.

These documents shall specify the species of trees suitable and desirable for planting in certain areas in order to establish a diverse urban forest. 3.0 DISCUSSION The City is updating its Engineering Standards in 2025. Updates to the City’s Master Tree List (Attachment A) that were reviewed by the Tree Committee in October 2022 but have yet to be reflected in the Street Trees Major List (Attachment B). Staff is proposing the changes proposed to the Street Trees Major List below (and highlighted in Attachment C) to correct errors on the document, update cultivars to reflect nursery availability , and make some minor revisions based on staff observations. Additionally, some species on the Street Trees Major Lists are either no longer available or are no longer suitable for the City’s climate or urban environment. Below is a list of the recommended changes proposed by staff. Links are provided that give more detailed information about the tree species discussed below. Replace Platanus x hispanica  It’s widely used on the list, but it is no longer in nursery production  Replace with Platanus x acerifolia ‘Columbia’, a more anthracnose resistant cultivar than ‘Bloodgood’  At creek crossings use Platanus racemosa Meeting Date: 2/24/2025 Item Number: 5a Time Estimate: 30 minutes Page 25 of 35 Item 5a Remove Lagerstroemia (Crape Myrtle)  No longer on the Street Tree Master List Update Ginkgo references  Ginkgo is utilized as a specific ‘Fairmont’ cultivar and then broadly  Adjust all to be Ginko biloba ‘Princeton Sentry’, a faster growing cultivar Remove Metrosideros excelsa  Not a performer in SLO’s climate  Remove it from Downtown accent trees list Remove Magnolia grandifolia ‘little gem’ and Magnolia ‘Majestic Beauty’ for all entries  Not a suitable street tree due to root damage  Susceptible to aphids and scale  Consider replacing ‘Little Gem” with Michelia doltsopa, a similar looking species with low root damage potential. Remove Fagus sylvatica (European Beech)  High water use, not suitable for climate Remove Pinus canariensis (Canary Island Pine) and Hesperocyparis macropcarpa (Monterey Cypress)  Not desirable as street trees Adjust Quercus (oak) entries to be broader (e.g. Quercus sp. “evergreen”)  Quercus ilex (Holm Oak) is susceptible to sooty mold on its leaves and has epicormic sprouts along trunk  Quercus rubra (Red Oak) and palustris (Pin Oak) are eastern oak species 4.0 ACTIONS 4.1 Recommend support of the proposed updates to the Street Trees Major Streets List (Engineering Standard 8020) and propose adjustments. This action may include recommendations to modify the proposed updates. 4.2 Continue the review to a hearing date certain, or uncertain. An action continuing review of the updates to the Street Trees Major Streets List (Engineering Standard 8020) should include direction to staff on pertinent issues. 5.0 ATTACHMENTS A - Updated Proposed Master Tree List B - Street Trees Major Streets Engineering Standard 8020 C - Engineering Standard 8020 Highlighted Page 26 of 35 All Trees for San Luis Obispo Botanical Name Existing City Tree New Addition City Tree Private yard ok MULGA Acacia aneura x BAILEY ACACIA Acacia baileyana x BLACKWOOD ACACIA Acacia melanoxylon x WEEPING ACACIA Acacia pendula x SHOESTRING ACACIA Acacia stenophylla x PINEAPPLE GUAVA Acca sellowiana x BIGLEAF MAPLE Acer macrophyllum x (native) BOX ELDER Acer negundo x EVERGREEN MAPLE Acer paxii x CALIFORNIA BUCKEYE Aesculus californica x AFRICAN FERN PINE Afrocarpus falcatus x PEPPERMINT TREE Agonis flexuosa x SILK TREE Albizia julibrissin x SYDNEY RED GUM Angophora costata x MARINA MADRONE Arbutus 'Marina'x KING PALM Archontophoenix cunninghamiana TC ?
