Describe – Arboricultural or Historical Interest: An Environmental Checklist Prepared by Jeff Oliveira of Oliveira Environmental Consulting LLC for a proposed multi-family residential development located at 71 Palomar Ave. stated the following: “No heritage trees or signiﬁcant native vegetation exist on the portion of the site to be developed. Multiple small to fully mature native and non-native landscaping trees would be removed as part of the proposed project development. This includes mulberry trees/ shrubs, pine trees, olive trees, decorative palms, larch or spruce trees, eucalyptus and redwood trees. The proposed project includes a conceptual landscape plan showing the removal of all of the existing vegetation with the exception of a 28-inch diameter eucalyptus tree at the southwest corner of the site and a 74-inch palm tree midway along the east property boundary.” This report neither properly identiﬁes the mature non-native vegetation located on this property nor does it acknowledge the health, rarity or maturity of this vegetation. The proposed project will involve the removal of all of this vegetation with the exception four trees. An Arborist Report for the 71 Palomar Avenue Project for the City of San Luis Obispo prepared by Rincon Consultants Inc. made the following observation: “The majority of the trees are in fair to poor condition. Some of them are stressed due to lack of water, competition with neighboring trees, pests, or have been topped and now have limbs with poor connection to the trunks. Observations of health for each tree are noted in Table 2.” However, among the largest, rarest trees slated for removal, 8 are in good health, 5 are in fair health and one is in poor health. For those trees identiﬁed as being stressed due to lack of water, their health can be restored with little more than the installation of an irrigation system. For it’s conclusion Rincon Consultants states the following: “The City’s Heritage Tree Program is voluntary, and none of the trees at the site are currently so designated. The City’s Heritage Tree webpage provides information about the currently designated heritage trees in the City. Based on the available information from that page, the heritage trees are associated with historic buildings/events/ properties, have unusual character, or are of an unusual size. While several tall healthy trees are present, none of the trees have unusual character nor are they of unusual size for their species. The Norfolk Island pines are approximately 70 feet in height but can reach as high as 160 feet. The healthy Canary Island palm is approximately 50 feet in height but can reach as high as 75 feet. Furthermore, per the Applied Earthworks, Inc. Update to Archaeological Resource Inventory, Signiﬁcance Evaluation, and Design Review (May, 2, 2016) prepared for this project, “the original historical landscape and setting have been materially altered by prior development... As a result, the integrity of the historic landscape and setting have been substantially diminished by prior development.” The City Cultural Heritage Committee during their review of the project did not ﬁnd that the landscaping elements present contributed to the historic nature of the property. Based on these assessments, the trees at the site do not meet the historical context criteria to be classiﬁed as heritage trees. It is our opinion that the proposed tree removals are compliant with the tree ordinance.” Rincon mistakenly states that the City’s Heritage Tree Program is “voluntary”. However, the City Municipal Code clearly states that “voluntary cooperation” applies to “privately owned trees” while “required cooperation” applies to “tree preservation in new developments”. Rincon mistakenly states that while heritage trees are associated with historic buildings/ events/properties, have unusual character, or are of an unusual size, these trees slated for removal have neither unusual character nor unusual size for their species. As clearly illustrated elsewhere, there are at least 14 trees slated for removal which have a strong association with the historic Sandford House and all of them are unusual for their size. Finally, Rincon is mistaken that the cultural landscape has been materially altered as the symmetrical plantings of the two Norfolk Pines and the two Eugenias - appropriate to Italian Renaissance revival architecture - remain in place and tree species typical of Italian Renaissance revival architecture (i.e., Olives, Stone Pines and Frond Palms) are also very much present on this property (in this regard, see the two attached documents). 2 - Araucaria hetrophylla or Norfolk Island Pine (unique specimens & some of the oldest in SLO) 2 - Grumichama Eugenia brasiliensis or Eugenia (2 of the oldest) 1 - Pheonix Canariensis or Frond Palm 1 - Pinus pinea or Italian stone pine 1 - Olea europaea or European olive 18 - Eucalyptus Globulus or blue gum North to South encircling house: Height: ave. 180’ East to West along Luneta 1 - Quercus agrifolia or native coastal oak ! Plot Plan The following (see below) is what the City of San Luis Obispo Municipal Code says about Heritage trees. It does NOT say the owner must sign an application. In fact, it is clear that the public MAY PROPOSE DESIGNATION of ANY healthy tree. The Arborist and Tree Committee will review it. The only place the owner explicitly comes in is when the Council makes the designation. But up to that time -- the investigative phase, the educational phase -- the process is indeed open to anyone pursuing a designation and the Tree Committee must consider this request. Trees That Form A Part Of The Cultural Landscape Like historic buildings and districts, cultural landscapes reveal aspects of our country's origins and development through their form and features and the ways they were used. Cultural landscapes also reveal much about our evolving relationship with the natural world. For example, the Italian Renaissance garden emerged in the late 15th century at villas in Rome and Florence, inspired by classical ideals of order and beauty, and intended for the pleasure of the view of the garden and the landscape beyond. In the late Renaissance, the gardens became more symmetrical. The symmetrical placement of the two Eugenias and the two Norfolk Pines relative to the entrance of the Sandford Residence should be preserved as they complement the Italian Renaissance revival architecture. Olives are natural choices for Italian-style gardens, or planted in formal lines ﬂanking a driveway or walkway. Similarly, the lone Stone Pine and Frond Palm, which were frequently planted within the context of Italian Renaissance gardens, should also be preserved. Trees That Are Either Endangered Or Historically Important Seven trees on the 71 Palomar property should be preserved both for their historical importance and for their rarity. Of the seven trees, two are Norfolk Island Pine, two Eugenia, one Frond Palm, one Italian Stone Pine and one European Olive. The trees are believed to have been planted by the owner, an orchardist, around 1895 when the historic Sandford residence was built. These trees are large and healthy specimens. They add beauty to the north part of San Luis Obispo and are accessible for viewing and enjoyment by the public. The City Arborist remarked recently “I have admired the trees at 71 Palomar for some time now and appreciate you and your group taking the time and effort to take pictures and ﬁll out part of the Heritage Tree Form. Thank you!…Bob and I feel very strongly about preserving canopy and habitat…”. Nevertheless, these trees are scheduled to be cut down for an apartment complex. Timely action by residents and the CHC/ARC may preserve them. Araucaria hetrophylla or Norfolk Island Pine are naturally long-lived and reach a height of 100’, making our local trees at over 65' very large specimens. In modern home landscapes, where frost-free climates or protected locations allow, Norfolks are known to live 150 years or more (see: The California Polytechnic State University SelecTree. "Araucaria Heterophylla Tree Record," 1995-2015). They are particularly tolerant of sandy soils and windy conditions. These pines are cylindrical at maturity. Due to its size, they are seldom seen in home landscapes and their use is limited to parks and botanical gardens. Norfolk Island Pines make spectacular specimen plants when situated on large expanses of lawn. Norfolk Island Pines are endemic to Norfolk Island located between New Zealand and New Caledonia. They were an early introduction into California by William Walker in 1859. These are the largest specimens in San Luis Obispo County having been planted only 25 years after this species was ﬁrst introduced into California. Eugenia brasiliensis, with common names Brazil Cherry and grumichama, is medium sized tree (maximum 65’ height) endemic to Brazil which bears small fruits that are purple to black in color, and have a sweet cherry-like ﬂavor. Its slow growth and low rate of dispersal make it rare, and it's generally considered an endangered species. Although Phoenix canariensis or Frond Palm grows just six inches a year and requires many years to attain full height. But because the tree grows so slowly, needing decades to reach its full height of 60 feet, very few nurseries even try to grow it. Exceptionally tall specimens can be up to 120 feet. The rare full-grown trees can fetch $20,000. While best in full sun and the usual well-drained loamy soil, P. canariensis can tolerate a wide range of exposures, including deep shade, and a wide range of soil types, including sand and heavy clay. It has a unique ability to tolerate both severe drought and ﬂooding very well, which makes them ideal to plant in housing tracts in which the soil was heavily compacted. Frond Palms dating back to the 1880's are middle aged and some live to be over 400 years old. The pinus pinea or Italian Stone Pine is a coniferous evergreen tree that can exceed 82’ in height, but 40’–65’ is more typical. In youth, it is a bushy globe, in mid-age an umbrella canopy on a thick trunk, and, in maturity, a broad and ﬂat crown over 26’ in width. In Italy, the stone pine has been an aesthetic landscape element since the Italian Renaissance garden period and is frequently planted within the context of Italian Renaissance architecture, such as is the case with the Sandford Residence. Britain’s Kew Gardens has records of one of these Mediterranean beauties that attained an age of 300 years. Olea europaea, commonly called Common Olive, is an evergreen tree that is native to the Mediterranean region. It typically grows at a slow rate to 20’-30’ tall with a rounded crown. Common olive trees are drought tolerant once established. The lifespan of the European Olive tree ranges from 300 years to 600 years. The Italian Stone Pine was frequently planted within the context of Italian Renaissance gardens. The Italian Renaissance garden emerged in the late 15th century at villas in Rome and Florence, inspired by classical ideals of order and beauty, and intended for the pleasure of the view of the garden and the landscape beyond. In the late Renaissance, the gardens became more symmetrical. “The upper class, however, wanted European reﬁnement, not rustic gardens. They favored aspects of Italian Renaissance gardens, with axial designs, fountains, and parterres, and the warm climate allowed them to incorporate into this frame a potpourri of exotic ornamental plants that would not grow outdoors in Europe or back east. They enjoyed living and entertaining outdoors here, appreciating the view of well-tended gardens with rose bushes an palm trees…” To: SLO Tree Committee  Re: New Business: Review 71 Palomar Drive Development Plan From: Allan Cooper, San Luis Obispo  Date: December 12, 2016 Honorable Chair Ritter and Committee Members - An Environmental Checklist Prepared by Jeff Oliveira of Oliveira Environmental Consulting LLC for a proposed multi-family residential development located at 71 Palomar Ave. stated the following: “No heritage trees or signiﬁcant native vegetation exist on the portion of the site to be developed.

As for the proposed clear cut of 55 specimen trees at 71 Palomar: Based on my reading of the Heritage Tree Program Of San Luis Obispo Information Packet And Form: http://www.slocity.org/ home/showdocument?id=4743 , I wish to alert you to the following: When and if the City Arborist meets with the ARC he can not unilaterally make a determination which of the 55 trees at Palomar are Heritage Trees. This determination can only be made by you - the Tree Committee - and City Council. All that the Arborist is unilaterally empowered to do is recommend removal of any tree that is deemed sick and/or will present a danger to the public because of imminent structural failure. The Palomar trees fall under the category of “Required cooperation – tree preservation in new developments, etc.” (see above website). In other words, because these trees are part of a new development, voluntary cooperation (presumably on the part of the owner) is not required. A precedent for this was established back in 1986 when a group of citizens undertook to save a mature Torrey Pine proposed to be removed to make way for an apartment complex. 1 The City Arborist previously stated that there are only two trees on the property that qualify as Heritage Trees. This assessment is false for a number of reasons: •These long-lived trees have historical interest because they most likely were planted by the original owner who later happened to be an “orchardist” in Santa Clara, CA. Torrey Pine - 1185 Foothill 1 Pinus torreyana  Dedicated: February 18, 1986 Torrey pines reach a height of 70', making our local tree at over 65' a very large specimen. These pines form a broad, round head at maturity with sparse foliage covering its branches. Its seeds are edible and were used by native Americans for food. Due to its size, it is seldom seen in home landscapes and its use is limited to parks and botanical gardens.    This tree was to be cut down for an apartment complex, but timely action by residents and the City Council preserved it. This tree is the largest specimen of its species in San Luis Obispo County and unique to this area. Torrey Pines are found naturally only on Santa Rosa Island and along the San Diego Coast. They also belong to a “cultural landscape” because of their relevance to the Sandford 2 House architectural style and because of the symmetrical disposition in which they were planted.

Their age could and should be veriﬁed by coring into the bole and counting the rings. •Several of these trees are unusual specimens and because of their size are seldom seen in home landscapes. Rincon Consultants Inc. Recommended Tree Removals3 Removal of Tree #2 (left side of entrance to house): Norfolk Island Pine: 60-65 feet tall: fair health Norfolk Island pines are naturally long-lived. Though not true pines, they're part of a plant family that dates back to prehistoric times. “In modern home landscapes, where frost-free climates or protected locations allow, Norfolks are known to live 150 years or more. Along parts of the California Coast, Norfolk Island pines grow 100 feet or taller, stretching up to 60 feet wide and growing up to 2 feet per year.” (source: The California Polytechnic State University SelecTree. "Araucaria Heterophylla Tree Record," 1995-2015). On their native Norfolk Island, east of Australia, they're known to grow twice as tall. http://www.pennington.com/resources/fertilizer/indoor-gardening/nurturing-norfolk-island-pines-year-round Removal of Trees #3 (to the left of tree #2 when facing entrance to house), #3A & 6 (up against the right front corner of the house): Pittosporum spp.: 20-25 feet tall: good heath “Pittosporum plants tend to live to at least 50 years old and may live as long as 150 years. Pittosporums usually grow to between 20 and 35 feet, though they may be kept smaller with pruning.” http://homeguides.sfgate.com/fast-pittosporum-plant-grow-77521.html Removal of Trees #14 & #15 (along the north property boundary): Canary Island palm: 45-55 feet tall: 1.5 foot trunk diameter: fair-good health “Single-trunked, pinnate palm to 20 m (66 feet) or more tall; exceptionally tall specimens can be up to 40 m (120 feet). The trunk is 60 - 90 cm (2-3 feet) in diameter, often with a much wider base.” http://www.palmpedia.net/wiki/Phoenix_canariensis Removal of Trees #16, #18 & #19 (at the northeast corner of the property boundary): Atlas cedar: 35-45 feet tall: 20-35 feet width canopy: fair-good health “As a youngster the tree is stark…but eventually it grows into a 60-foot tall tree that can be 35-feet across.” http://www.uaex.edu/yard-garden/resource-library/plant-week/blue-atlas-cedar.aspx Removal of Tree #43 (south of trees #2 & #3): Stone pine: 35 feet tall: poor health “Just as its name implies, umbrella pine has a broad, somewhat ﬂattened round canopy, and the tree will ultimately reach 80 to 100 feet in height though it is more often seen at 35 to 45 feet tall and wide.” http://edis.ifas.uﬂ.edu/st472 Removal of Trees #39 (near the garage), #41 (on the southern property boundary) & #44 (due west of tree #39): Olive or Olea Europe: 35 feet tall: 35 feet width canopy: fair-good health “The olive tree can reach up to and sometimes over 40 feet tall at maturity, spreading out with a large rounded crown. The crown of leaves can spread outward as far as 20 feet from the trunk, making the spread of the olive tree as wide as it is tall.” http://homeguides.sfgate.com/olive-tree-growth-rates-56428.html Removal of Tree #48 (on the southern property line): Monterey pine: 35 feet tall: 25 foot wide canopy: good health “It grows from 80 to 100 feet tall and from 25 to 35 feet wide.” http://slobg.org/monterey-pine/ The Tree Committee has the responsibility to inform the ARC and the CHC of these ﬁve following points: condition/health, permanence of site location, visual accessibility, arboricultural interest and historical interest The owner in the sample “Owner Agreement” may say he/she does not want their trees designated as a “Heritage Tree” and/or does not want their trees included on a self-guided Heritage Tree tour. However, this form does not forbid the City, in spite of the owner’s refusal, to see if these trees “qualify” as “Heritage Trees”. Without this determination, the ARC could not, as Michael Codron conﬁrmed, do the following: “The Architectural Review Commission has the authority to require preservation of trees on the project site as a condition of approval, if the appropriate ﬁndings can be made.” Thank you!
