Van Nort, City Manager FROM: James DeStefano, Community Development Director VIA: Ann J. Lungu, Planning Technician SUBJECT: Tree Preservation Ordinance (Zoning Ordinance Amendment No. 91-5) DATE: March 2, 1992 BACKGROUND• In preparing this preliminary draft tree preservation ordinance, research was done using ordinances which are in effect at other cities. Sections were taken from these ordinances which seem compatible with our community for our purpose and intent. The following cities' tree preservation ordinances were used: Thousand Oaks, Rancho Cucamonga, LaVerne, San Marino, San Dimas, and Los Angeles. An ordinance prepared by Don Schad for the City of Diamond Bar was also used in the research. A pamphlet prepared by the Los Angeles County Department of Forester and Fire Warden was used. The Commission met on June 24, 1991, August 12, 1991, and October 14, 1991 to discuss the issues surrounding a tree preservation ordinance. At the October 14,1991 meeting, the Commission decided the ordinance would be preserving not only species of oak trees but also species of walnut, sycamore and pepper trees. On December 9, 1991, staff presented the City's draft regulations concerning tree preservation in ordinance formate to the Planning Commission. Another public hearing was held on January 13, 1992 and the Commission adopted a resolution recommending approval of a Tree Preservation Ordinance to City Council. Attached to this memorandum is that Tree Preservation Ordinance. DISCUSSION: The purpose and intent of the Los Angeles County Oak Tree Ordinance and the proposed Tree Preservation Ordinance are similar. They indicate the importance and significance of trees to society and to our environment. The three major differences between the Los Angeles County Oak Tree Ordinance and the City's proposed Tree Preservation Ordinance are the type of trees which are protected, the replacement ratio, and the size criteria for trees which are preserved. The type of tree the Los Angeles County Oak Tree Ordinance protects are species of oak trees. The City's proposed Tree Preservation Ordinance will protect all genus and species of oak trees, walnut trees, sycamore trees, and pepper trees on all public and private property within the City. The tree replacement ratio of the Los Angeles County Oak Tree Ordinance is two to one (2:1) . The ratio for the propose Tree Preservation Ordinance is four to one (4:1). Lots less than one (1) acre with existing improvements are exempt for the 4:1 ratio unless the Director of Community Development determines that there are overriding considerations. The replacement ration for these lots are 1:1. For lots that are one (1) acre or more shall be replaced as in the scheduled found in Chapter 22.56, Section 2160.G. (Pg -9) of the proposed ordinance. The size criteria for tree preservation is drastically different in the ordinances. The Los Angeles County Oak Tree Ordinance states that a person shall not cut, destroy, remove, relocate, otherwise inflict damage or encroach into a protected zone of any tree of the oak genus which is as follows: 1. 25 inches or more in circumference (8 inches in diameter) as measured 4h feet above mean natural grade; 2. In the case of an oak tree with more than one trunk, whose combined circumference of any 2 trunks is at least 38 inches (12 inches in diameter) as measured 4h feet above mean natural grade, on any lot or parcel of land within the unincorporated area of Los Angeles County, or any tree that has been provided as a replacement tree, pursuant to Section 22.56.2180, on any lot or parcel of land within the unincorporated area of Los Angeles County, unless and oak tree permit is first obtained as provided by this part 16. In the City's proposed Tree Preservation Ordinance, the following standards apply: 1. All oak, walnut, sycamore, and pepper trees in excess of 15 feet in height or having a minimum single trunk circumference of 15 inches measured 4 feet form lowest ground level; 2. Multitrunked tree with a division of its trunk having a total circumference of a minimum of 30 inches measured 4 feet from lowest ground level 3. A stand of trees which are dependent on each other for survival or dominance. The importance of having a tree preservation is evident. Today, trees are recognized for their tremendous value to our Communities. Trees add beauty to our landscape, add value to our home, protect our wild life, and add to our well being. la 010161aa 0 a 114V 0 CUM The Planning Commission recommends Preservation Ordinance.

Mayor I, LYNDA BURGESS, City Clerk of the City of Diamond Bar, do hereby certify that the foregoing Ordinance was introduced at a regular meeting of the City Council of the City of Diamond Bar held on the 11 rcvised 12/26/91 day of , 1992, and was finally passed at a regular meeting of the City Council of the City of Diamond held on the day of , 1992 by the following vote: revised 12126191 12 RESOLUTION NO. 92-2 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF DIAMOND BAR RECOMMENDING THAT THE COUNCIL OF THE CITY OF DIAMOND BAR APPROVE THE REPEAL OF THE OAR TREE PERMIT PROCESS AND THE REPLACEMENT OF SUCH WITH A TREE PRESERVATION ORDINANCE. A. Recitals. (i) The City of Diamond Bar is recognized for its unique and distinguished natural and improved physical environment. A major element of such physical environment is the varieties of trees, including naturally occurring stands of oak, walnut, scyamore and pepper trees. These trees value to the community is such that all reasonable efforts should be. undertaken to preserve and enhance them. Such measures must also be balanced against the circumstances which may require the removal, relocation or maintenance of such trees. (ii) The City of Diamond Bar presently is without adequate regulations which serve to foster the preservation of such trees while responding to the needs of owners of the properties on which such trees may be sited. (iii) The Planning Commission has extensively considered the issues related to a balanced tree preservation ordinance, and has, with the benefit of public input, developed a proposed tree preservation ordinance which it hereby recommends to the City Council for its review and adoption. (iv) All legal prerequisites to the adoption of this Resolution have occurred. 1 B. Resolution. NOW, THEREFORE, the Planning Commission of the City of Diamond Bar, California finds and resolves as follows: SECTION 1. In all respects as set forth in the Recitals, Part A, hereinabove. SECTION 2. That the Diamond Bar Planning Commission recommends that the Council of the City of Diamond Bar approve and adopt the proposed tree preservation ordinance attached hereto as Exhibit 11111. SECTION 3. That the City of Diamond Bar is in the process of finalizing its draft General Plan and that, on the basis of such draft plan there is a reasonable probability that the intent of this Ordinance will be consistent with the goals, e`s policies and objectives of the ultimate General Plan. Further, there is little or no probability of substantial detriment to or interference with the ultimately adopted general plan if inconsistencies are ultimately present because the preservation of both the naturally occurring and introduced trees.will enhance the City and the environment which will be of benefit to the present and future community. Finally, this action is undertaken in conformance with all applicable laws. SECTION 4. The Planning Commission finds and determines that the ordinance proposed by this Resolution is categorically exempt from the requirements of the California Environmental Quality Act of 1970, as amended, and the Guidelines promulgated thereunder pursuant to Section 15307 of Division 6 of f 2 s> Title 14 of the California Code of Regulations. �,tyd SECTION 5. That the Secretary to the Planning Commission deliver this resolution to the City Clerk. ADOPTED AND APPROVED this 13th day of January, 1992. Chairman I, JAMES DESTEFANO, Secretary of the Planning Commission of the City of Diamond Bar, do hereby certify that the foregoing Resolution was introduced at a regular meeting of the Planning Commission of the City of Diamond Bar held on the 13th s �a day of January, 1992, and was finally passed at a regular meeting of the Planning Commission of the City of Diamond Bar held on the 13th day of January, 1992, by the following vote: AYES: COUNCIL MEMBERS: GROTHE, HARMONY, FLAMENBAUM and SCHEY NOES: COUNCIL MEMBERS: None ABSENT: COUNCIL MEMBERS: MCBRIDE ABSTAINED: COUNCIL MEMBERS: None ATTEST: Secretary L�1011%USOTREE%DB 6.7 3 MINUTES OF PLANNING COMMISSION MEETING JUNE 24, 1991 Draft Tree Preservation Ordinance PT/Ann Lungu addressed the Commission regarding a draft Tree Preservation Ordinance. The primary need is to determine to what extent the Commission would like this ordinance to establish the policies for the City of Diamond Bar's tree preservation. Staff would appreciate comments and suggestions on the ordinance. VC/Harmony made the following suggestions for the Ordinance: the definition of multitrunk trees is unclear; there should be some special leeway to allow closer buildings within the drip line; nurseries should be included; the City should be involved in the certification of the diseased tree; the City Engineer should have to process a request at some level; Public Utility should not be given authority over Oak Tree/Heritage Tree without some review; the pruning % of the whole tree may be a more appropriate approach to regulating trimming; there should be a provision for allowing instances to chop tree tops, as well as trimming and pruning; the concepts of item G & H, under the Oak Tree/Heritage Tree Permit Application, needs clarification; there should be a longer time period to allow for an appeal; change "dangerous condition" to "eminent danger", under Emergency Waiver; clarify the difference between a horticulturist and an arborist; the responsibility for maintaining replacement trees should be 5 years; broaden the definition concerning the replacement of trees with the largest available tree; the Protection of Existing Trees during construction should include maintenance; and the Enforcement Officer should have code enforcement authority. Chair/Schey questioned the appropriateness of a blanket statement requiring Oak Trees/Heritage Trees to be replaced by the largest available tree. There needs to be more flexibility to deal with particular situations. C/MacBride would like to include, in the list of exceptions, a consideration for trees on private property that require topping to prevent damage to the existing structures to the property. He suggested being more selective on the definition of a Heritage Tree, with consideration of historic inferences. C/Lin stated that fencing, for the Protection of Trees, may not always be warranted. She suggested the statement should include "where necessary and feasible". STUDY SESSION: October 14, 1991 Zoning Code Amendment 91-5 (tree preservation) PT/Lunge addressed the Commission regarding the proposal to amend certain provisions of the Los Angeles County Code, as adopted by Diamond Bar, pertaining to Tree Preservation. In preparing the various drafts for the tree ordinance, research was done using sections of ordinances from the cities, indicated in the staff report, that seemed compatible with our community for our purpose and intent. It is suggested that the Commission address the following four main issues regarding the tree ordinance: the criteria to be used to identify trees to be preserved; the minimum lot size standards for activation of a tree preservation ordinance; the replacement ratio and size of replacement tree that would be appropriate for the City's tree preservation ordinance; and the City's desire to insure that a replacement tree will receive the proper care and maintenance for a designated period of time. It is recommended that the Commission direct staff to prepare a "final" ordinance with the conditions listed by staff. CD/DeStefano stated that DCA/Curley has suggested some clarifications of items in the tree ordinance. Staff will review these at the end of discussion on the four main issues. He suggested that the Commission begin discussion regarding the criteria to be utilized. Chair/Grothe indicated that the criteria, for the replacement of trees on single family properties, should not be such that it is difficult to enforce. C/Schey suggested that a 1:1 replacement ratio is sufficient on a single family residential lot. Chair/Grothe concurred that a 1:1 replacement ratio is adequate, as long as it pertains to only the trees in the preservation list, and not all types of trees. CD/DeStefano inquired if a 1:1 replacement ratio would be adequate in a situation where the tree removed was quite old. C/Schey responded that, in that situation, no tree could adequately replace it. Chair/Grothe stated that the 4:1 replacement ratio for the removal of a Heritage tree makes sense on a hillside development, but not within a single family residential yard. C/Harmony stated that the Pepper Tree should be added to the Heritage Tree list. VC/MacBride indicated the following concerns: the definition of a Heritage tree is much too broad; the problem of a developer choosing to pay the fine, rather than leave a cluster of trees, must be addressed; and the issue regarding public safety vs. the preservation of a tree included in the protective category, need be addressed. C/Schey suggested differentiating between a Heritage tree and a Significant tree. Heritage trees are indigenous trees like the Oak, Sycamore, Walnut, and Pepper. The Significant trees are those that have reached some significance due to maturity or historical value. Short of public safety, there should be absolute preservation for Heritage trees. CD/DeStefano stated he has suggested to Staff eliminating the term "Heritage Tree" because he felt the ordinance was simply a tree preservation ordinance beginning with whatever size, species or combination we choose to establish as the minimum tree which we desire to protect. During Staff's research it became apparent that there is no common definition as to what the term "heritage tree" or "significant tree" means. Chair/Grothe pointed out that the original intention of this ordinance was to try to save the majority of the tree groves mostly located in the undeveloped areas of town. Therefore, the care of trees, located on lots under a specified size, should be left to the discretion of the homeowner. The Public Hearing was declared open. Dan Buffington, residing at 2605 Indian Creek, emphasized the importance of preserving trees now for the future. Don Schad, residing at 1824 Shady Wood Rd., suggested that the concern for tree size, per lot, and tree types should be carefully considered by a group of arborists, perhaps from a local college. He explained that a Heritage tree is a tree that has been able to sustain itself through it's own natural environment. He also suggested that all the species be protected that have a uniqueness to them. C/Schey suggested that the general tree population should not be preserved until there's some reason to believe that it is being threatened. The native tree should be established as protected. CD/DeStefano reminded the Commission that staff needs specific direction regarding the four major criteria issues previously indicated by staff. VC/MacBride suggested defining Heritage trees and Significant trees separately. Heritage trees would include Oak, Sycamore, California Pepper, and Black Walnut. Significant trees are trees that have a definitive historical significance, have a factor of age, and are outstanding in it's own individual growth, per species. PD/DeStefano stated that the Commission needs to be more specific with their definition of a Significant tree. If the Commission is unable to define it now, staff can, with the Commission's approval, attempt to come up with a differentiation between Heritage trees and Significant trees, and return it back to the Commission in an ordinance format. He then suggested that the Commission discuss if they want to differentiate any replacement value to the Heritage tree, the Significant tree, and all others trees. C/Harmony inquired if the Commission is in concurrence that single family residential lots are exempt. VC/MacBride suggested that the four stated categories of a Heritage tree, plus the historic attributes of a given tree, as well as significant trees be placed in one category called "Heritage Trees", and exempting those problems which arise on single family residential lots of a certain size. Chair/Grothe suggested, and the Commission concurred on, the following: the four types of Heritage trees, Oak, California Pepper, Walnut, and Sycamore, are protected everywhere and can be removed only by permit; all other trees that exceed the 15' height, and 15" circumference criteria fall in the Significant tree category and require a permit if they are on nonresidential or undeveloped residential property; trees with documented historic significance require a permit; there is a 1:1 replacement ratio, for Heritage trees, on existing developed residential properties; there is a 4:1 replacement ratio for Significant trees on non residential or undeveloped properties; the replacement tree should be of an in-kind species; there should be a steep penalty for trees removed without a permit; the size of the replacement tree is to be determined per the City of La Verne graph; and anyone removing a tree should be required to place a bond for insuring maintenance of the replacement tree. CD/DeStefano pointed out those items in the draft tree ordinance that will need further clarification: the definition of a Heritage tree will be expanded, and the definition of "multi-trunk" and "stand" needs further clarification; the verbiage regarding "Routine Maintenance" will be moved to the Exception clause; verbiage will be added to the Exception clause requiring that a damaged tree, or diseased tree, be verified by a certified arborist; in the Tree Permit Application, we must assure that the plans indicate the existing and the proposed structures; the amount of photographs required must be clarified in the Tree Permit Application; the verbiage, of item F of the Tree Permit Application, will be changed to indicate that "the applicant may be required to provide..."; add in the Tree Permit Application a specified time period in which the director will give a forthcoming decision; there also needs to be a time period indicating when the Director's decision will be received regarding the Tree Pruning Permit, item B; the issue regarding public safety vs. convenience will be addressed in the pruning of a tree section; the word "unbalanced", written on page 6, will be better defined; under Emergency Waiver, defining the proper contacts will be better stated; the word "acceptable" will be changed to "approved" in the section Protection of Existing Trees, section A & B; the phrase "unless otherwise approved by the Director" will be added to subsection E, of Protecting Existing Trees; and the last paragraph of the section Enforcement, will be removed. VC/MacBride, concerned with developers that may inadvertently or intentionally remove trees, suggested that instead of imposing a penalty, require that the trees be replaced in-kind and maintained. DCA/Curley stated that if a tree is removed, accidently or otherwise, the developer could be asked to stop the project, or meet the conditions that have been established. There are ways to reach the developer. Don Schad suggested that the required period of maintenance be extended from three years to five years. The Commission concurred with Don Schad's suggestion to extend the period of maintenance to five years. Chair/Grothe, concerned with the administrative burden on staff for enforcement, suggested that the bond requirement for a single tree on a single residence be excluded. DCA/Curley suggested, and the Commission concurred, to use a lien process rather than requesting a deposit or bond up front. The Public Hearing was declared closed. As directed by the Commission staff will renotice the Public Hearing when the ordinance is ready to be brought back to the Commission. Motion was made by VC/MacBride, seconded by C/Harmony and CARRIED UNANIMOUSLY to request staff to bring the ordinance back to the Commission the first meeting in December of 1991. Minutes of Planning Commission Meeting August 12, 1992 Preliminary Draft Tree Preservation Ordinance ZCA 91-3 PT/Lungu addressed the Commission regarding the second draft of the tree preservation ordinance. Comments from the Commission are requested. The next time the Commission meets to discuss this topic, it will be in ordinance form, and a public hearing. VC/MacBride made the following comments: Under Purpose, amend the phrase "as well as defined" to "definitive of"; under Intent and Applicability, the ordinance should pertain to both public and private property; and page 3, under Exception C, include shrubs, and add the wording "... necessary to keep street and sidewalk easements clear of obstruction..." C/Schey requested that the syntax "shall mean", "mean", etc. be eliminated from the Definition section. He also stated that defining a Heritage Tree, simply by size, seems to be an overly broad definition. VC/MacBride requested staff to review the item, possibly with Don Schad, and reword it. Following discussion, C/Schey suggested that the Significant Tree and the Heritage Tree be differentiated. The Heritage Tree can have the full review it is warranted, and the Significant Tree have at least some review. C/Harmony made the following comments: Under Diseased Trees, staff should include some reference to insect infestation, as well as wording indicating "and others inflicted by, but not limited to."; he indicated concern regarding the 2 inch guideline referred to in the Routine Maintenance section and Pruning Permit section; in reference to the removal or relocation of oak trees or heritage trees, some significant tree removal should remain in the purview of the Planning Commission and the Council; and on page 7, item E, replacement trees should be maintained for a period of five years. C/Schey discussed item E, page 5, regarding the enforcement of replacement trees. A warranty period of 3 to 5 years is a long time, and often the developer has become unavailable. He suggested that language be included in the context that the applicant, permittee, or successor, whoever is responsible for that property when the tree is removed, is responsible for the replacement trees. C/Harmony suggested that a provision for paying the City the appraised value of the lost tree, if it cannot be replaced, be included with the tree replacement clause. C/Schey, noting that often times developers view the fines as a more desirable option, requested staff to review the provision in Claremont, which carries a heavier penalty. C/Lin inquired how the capabilities of tree specialists are differentiated. PT/Lunge stated that they must have proof of qualifications and references of past work. VC/MacBride requested staff to determine if there is a California requirement that establishes standards which indicates that the specialist is licensed, bonded, or certified. Chair/Grothe noted that, in the replacement of trees, quantity is not discussed. Understanding that tree sizes and types must be varied, he cautioned that unless there is a minimum replacement number indicated, some developers will manage to elude the specifications. PD/DeStefano stated that a section will be added pertaining to the replacement ratio, and the issues pertaining to the size of the replacement trees. He then stated that, with the Commission's comments, staff will prepare the document in full ordinance format, and establish a public hearing process for the Commission's recommendation to the City Council. MINUTES OF PLANNING COMMISSION MEETING DECEMBER 9, 1992 PUBLIC HEARING: Zoning Code Amendment 91-5 PT/Lungu reported that the Commission, at the October 14th meeting, directed staff to have the draft tree preservation ordinance reformatted for the December 9th meeting. Staff recommended that the Commission adopt a Resolution recommending that the City Council approve the Tree Preservation Ordinance. VC/MacBride, concerned that a situation may arise whereas a developer may choose to pay the fine for destroying a forest of trees rather than hold up development, requested that' there be definitive language in the ordinance indicating that there is an enormous penalty for such a situation. The intent of such language would be to influence the developers to think long and hard before cutting down a forest of trees. C/Flamenbaum noted that section 5, of the ordinance, under Tagging, already indicates that the City would have a Civil right to sue for abatement of a nuisance, and damages that result. C/Harmony, concurring with VC/MacBride, stated that additional language, emphasizing the desires of the Commission, helps establish policy for future administrations and city attorneys to pursue these cases when they happen. DCA/Curley stated that provisions in nuisance abatement type ordinance is already structured, in essence, to say: "The City Attorney's office is hereby directed to institute proceedings." Wording to the effect, "... and shall seek to obtain remedial measures, including restitution or tree replacement.", could be added to the provision and could be appropriately placed in Section 5, of the ordinance, to amplify the intent. However, the overall legal impact may not be effective. He reminded the Commission that, procedurally, the Council must first authorize, and direct any and all litigation to proceed. C/Schey suggested, and DCA/Curley concurred, that it may be more appropriate to place a policy statement, in the beginning of the Ordinance, under the Purpose and Intent Section, indicating that it is the intent of the City to preserve these trees, and we will pursue to the greatest extent. VC/MacBride, in reference to the tree guidelines manual, inquired if a statement could be incorporated into the ordinance stating that each applicant, under this section, shall be furnished, by the City, with a copy of the guidelines. DCA/Curley stated that, since the City does not have certified arborists that can examine each individual tree and give instructions as to it's proper care, it is strongly advised that these guidelines are eliminated to avoid future potential liability. C/Schey inquired if it is the City Attorney's recommendation that the City leave the care and feeding of the trees as the responsibility of the owners, or responsible party, to keep them alive. The City would then intervene if the trees should die. DCA/Curley concurred. Chair/Grothe questioned why a disclaimer could not be placed in the ordinance, stating that the guidelines is just information gathered to help in caring fora tree, and is not the full direction of the City. CD/DeStefano suggested that the Commission may opt to send the guidelines to the City Council, with the understanding of the City Attorney's office's concerns, and including the Commission's comments, but ultimately letting the City Council decide whether or not the guidelines are an appropriate attachment to the ordinance. The Commission concurred. C/Schey, concerned with section 22.56.2080 Definition (J) of the ordinance, stated that, to his recollection, it was the Commission's intent to establish an ordinance that preserves all Oak, Sycamore, Walnut, and Pepper trees, regardless of size. There seems to be an inconsistency. Chair/Grothe stated that he was under the impression that there would be a provision exempting residential homeowners from the preservation provision. CD/DeStefano reminded the Commission that they had developed the criteria for the size of the tree appropriate for preservation, after discussion on the matrix presented by staff, which included information as to what some other cities in the immediate area were doing. The Public Hearing was declared open. Don Schad made the following comments: There are other significant trees based upon size and heritage, other than the four indicated trees, that should be considered for preservation; the height and circumference limit is bearable as stated in the Definition section (J).1, but he suggested adding the word "dominance" after the word "survival" to (J)3., page 3; a relocated tree should be given the same care and consideration as a brand new tree; there is not a specific chart on tree sizes; and pages 1 through 11, of the ordinance, does not identify dimensional sizes for tree replacement. The Public Hearing was declared closed. Chair/Grothe stated that he was under the impression that the draft tree ordinance referred to a chart of sizes and quantities regarding tree replacement. DCA/Curley suggested that there should be flexibility on tree replacement ratios because site sizes may vary, and the trees may or may not fit as directed. The replacement ratio is currently at the Director's discretion, so that he may analyze the site and either determine the rational replacement ratio, or refer it to the Commission. C/Flamenbaum suggested that section 22.56.2160 Tree Replacement Standards item A, should read, "... on the basis of the Tree Report.". Chair/Grothe stated that he would prefer the ordinance to include specific replacement quantities or sizes so that when the developer pulls a permit he is immediately made aware of the guidelines he must follow. C/Schey stated his concern that, the way the ordinance is written, all tree removal permits would come before the Director and would not come before the Commission unless it is under appeal. CD/DeStefano recommended that, in order to clarify that the Planning Commission should review not only the tree removal, but all other environmental aspects of a project at the time that they are reviewing the specific project, subsection E. should be added to section 22.56.2100 Permit Required, stating that, "The Director, in his/or her discretion, shall refer the decision to the Planning Commission in the event that such application is in conjunction with the discretionary approval over which the Planning Commission has jurisdiction.". C/Schey, regarding the drafting of the tree report, noted that a situation could arise whereas the impartiality of the arborist could be questioned. He suggested that the arborist be employed by the City to ensure that he/she has the City's, and the tree's, best interest at heart. DCA/Curley concurred that the present structure of the ordinance looks to the applicant to employ the arborist. It could be modified whereas the applicant up fronts the cost, and the City would then employ the arborist who would analyze the situation impartially. C/Harmony noted that there is no provision in the ordinance protecting heritage trees that are significant because of size, age, or historical event, other than the four trees indicated. DCA/Curley suggested that the Commission may consider separating cultural significant attributes, versus the broader environmental significance, and designating those attributes within a separate culturally significant ordinance. CD/DeStefano indicated that, at this point and time, staff needs specific direction from the Commission as to how the Commission wishes staff to proceed on this issue. It is difficult for staff to determine historical events recognized by the City. C/Harmony stated that the historical value can be certified by the Planning Commission and/or the City Council, or the historical committee being formed. He would like heritage trees protected in the ordinance. C/Flamenbaum suggested that the ordinance be approved, with the recommendations and corrections made. If the Commission desires historical items to be preserved, then a separate ordinance should be created. The Commission concurred. C/Harmony stated, for the record, omitting reference to heritage trees, within the tree ordinance, limits the scope of the ordinance, and is therefore, not a complete ordinance that way. C/Harmony, referring to the civil remedies, section 22.56.2180 Tagging subsection 5., stated that it is not clear what kind of civil remedy the City would receive if the developer destroyed, for example, a 600 year old tree. There should be a clearly stated penalty that the developer will be responsible for replacing the tree, and that a neutral arbitrator will be utilized to appraise the tree, if needed. DCA/Curley recommended that the wording of subsection E not be altered. The provision gives full flexibility to pursue whatever remedy is deemed appropriate by the City Council. It is understood that the City would seek replacement or replacement costs. CD/DeStefano suggested that the Chair may wish to appoint a sub- committee, of the Commission, to work out the specific details and assist staff in bringing the matter back to the full Commission in January of 1992. C/Schey recommended that the subcommittee limit their discussion on the following two issues that remain unresolved: the delineations of the penalties; and the minimum replacement standard. C/Schey and VC/MacBride volunteered to be on the subcommittee. C/Schey recommended that the matter be continued to January 13th, with the subcommittee working with staff to reconcile these matters, and bringing it back to the Commission in final form on that date. The Commission concurred. VC/MacBride requested staff to appropriately revise section 22.56.2090 Exemptions subsection D. so that it is more clearly stated. Chair/Grothe called a recess at 9:35 p.m. The meeting was called back to order at 9:44 p.m. C/Flamenbaum suggested that the Commission recommend to the City Council to consider the establishment of an ordinance taking into account all historical items within the City confines. The Commission concurred. MINUTES OF PLANNING COMMISSION MEETING JANUARY 13, 1992 PT/Lungu reported that on December 9, 1991, at a noticed public hearing, staff presented a final draft tree preservation ordinance to the Commission for review. A subcommittee of two Planning Commissioners, C/Schey and VC/MacBride, were selected to deal with the issues of heritage trees, replacement standards, and civil remedies. PT/Lungu reviewed the decisions made by the subcommittee regarding the three issues, as indicated in the staff report. Staff recommended that the Commission adopt a Resolution, with additions resulting from the subcommittee meeting, recommending that the City Council approve the Tree Preservation Ordinance. Furthermore, it is recommended that the language, "The Director, in his/or her discretion, shall refer the decision to the Planning Commission in the event that such application is in conjunction with the discretionary approval over which the Planning Commission has jurisdiction.", should be inserted to subsection 22.56.2110 as a new addition after subsection H. CD/DeStefano explained that this addition would allow the Director to forward the application to the City Planning Commission for review. It is staff's opinion that applications for discretionary approval involving the removal of trees, should be reviewed by the Commission, including the removal of any Oak, Walnut, Sycamore, or Pepper trees. The Public Hearing was declared open. Don Schad complimented the Commission and staff on their job in developing the Tree Ordinance. The Public Hearing was declared closed. Motion was made by C/Schey, seconded by C/Harmony and CARRIED UNANIMOUSLY to approve the Ordinance as drafted, with the inclusion of the Director's discretion to send nondevelopment related permits to the Commission for their review, and the inclusion of provision mandating that tree removal permit that relate to development permits, under the Commission's discretion, be mandatorily brought with the balance of the package. Chair/Grothe called a recess at 9:25 p.m. The meeting was called back to order at 9:42 p.m. 1111/;'Ut; PART 16 - CHAPTER 22.56 OAK TREE PERMITS 22.56.2050 ESTABLISHED - PURPOSE. The oak tree permit is established (a) to recognize oak trees as significant historical, aesthetic and valuable ecological resources, and as one of the most picturesque trees in Los Angeles County, lending beauty and charm to the natural and man-made landscape, enhancing the value of property, and the character of the communities in which they exist; and (b) to create favorable conditions for the preservation and propagation of this unique, threatened plant. heritage,.particularly those trees classified as "heritage oak" trees, for the benefit of current and future residents of Los Angeles County. It is the intent of the oak tree permit to maintain and enhance the general health, safety and welfare by assisting in counteracting air pollution and in minimizing soil erosion and other related environ- mental damage. The oak tree permit is also intended to preserve and enhance property values by conserving and adding to the distinctive and unique aesthetic character of many areas of Los Angeles County, in which oak trees are indigenous. The stated objective of the Oak Tree Permit is to preserve and maintain as many healthy Oak trees in the development process. 22.56.2060 DAMAGING OR REMOVING OAK TREES PROHIBITED - PERMIT REQUIREMENTS.

Van Nort, City Manager FROM: James DeStefano, Community Development Di VIA: Ann J. Lungu, Planning Technician l SUBJECT: Tree Preservation Ordinance (Zoning Ordinance Amendment No. 91-5) DATE: March 2, 1992 BACKGROUND• In preparing this preliminary draft tree preservation ordinance, research was done using ordinances which are in effect at other cities. Sections were taken from these ordinances which seem compatible with our community for our purpose and intent. The following cities' tree preservation ordinances were used: Thousand Oaks, Rancho Cucamonga, LaVerne, San Marino, San Dimas, and Los Angeles. An ordinance prepared by Don Schad for the City of Diamond Bar was also used in the research. A pamphlet prepared by the Los Angeles County Department of Forester and Fire Warden was used. The Commission met on June 24, 1991, August 12, 1991, and October 14, 1991 to discuss the issues surrounding a tree preservation ordinance. At the October 14,1991 meeting, the Commission decided the ordinance would be preserving not only species of oak trees but also species of walnut, sycamore and pepper trees. On December 9, 1991, staff presented the City's draft regulations concerning tree preservation in ordinance formate to the Planning Commission. Another public hearing was held on January 13, 1992 and the Commission adopted a resolution recommending approval of a Tree Preservation Ordinance to City Council. Attached to this memorandum is that Tree Preservation Ordinance. DISCUSSION• The purpose and intent of the Los Angeles County Oak Tree Ordinance and the proposed Tree Preservation Ordinance are similar. They indicate the importance and significance of trees to society and to our environment. The three major differences between the Los Angeles County Oak Tree Ordinance and the City's proposed Tree Preservation Ordinance Tree Ordinance and the City's proposed Tree Preservation Ordinance are the type of trees which are protected, the replacement ratio, and the size criteria for trees which are preserved. The type of tree the Los Angeles County Oak Tree Ordinance protects are species of oak trees. The City's proposed Tree Preservation Ordinance will protect all genus and species of oak trees, walnut trees, sycamore trees, and pepper trees on all public and private property within the City. The tree replacement ratio of the Los Angeles County Oak Tree Ordinance is two to one (2:1) . The ratio for the propose Tree Preservation Ordinance is four to one (4:1). Lots less than one (1) acre with existing improvements are exempt for the 4:1 ratio unless the Director of Community Development determines that there are overriding considerations. The replacement ration for these lots are 1:1. For lots that are one (1) acre or more shall be replaced as in the scheduled found in Chapter 22.560, Section 2160.G. (Pg -9) of the proposed ordinance. The size criteria for tree preservation is drastically different in the ordinances. The Los Angeles County Oak Tree Ordinance states that a person shall not cut, destroy, remove, relocate, otherwise inflict damage or encroach into a protected zone of any tree of the oak genus which is as follows: 1. 25 inches or more in circumference (8 inches in diameter) as measured 4'h feet above mean natural grade; 2. In the case of an oak tree with more than one trunk, whose combined circumference of any 2 trunks is at least 38 inches (12 inches in diameter) as measured 4'h feet above mean natural grade, on any lot or parcel of land within the unincorporated area of Los Angeles County, or any tree that has been provided as a replacement tree, pursuant to Section 22.56.2180, on any lot or parcel of land within the unincorporated area of Los Angeles County, unless and oak tree permit is first obtained as provided by this part 16. In the City's proposed Tree Preservation Ordinance, the following standards apply: 1. All oak, walnut, sycamore, and pepper trees in excess of 15 feet in height or having a minimum single trunk circumference of 15 inches measured 4 feet form lowest ground level; 2. Multitrunked tree with a division of its trunk having a total circumference of a minimum of 30 inches measured 4 feet from lowest ground level 3. A stand of trees which are dependent on each other for survival or dominance. The importance of having a tree preservation is evident. Today, trees are recognized for their tremendous value to our Communities. Trees add beauty to our landscape, add value to our home, protect our wild life, and add to our well being. RECOMMENDATION• The Planning Commission recommends approval of the Tree Preservation Ordinance.

The City Council declares that, should any provision, section, paragraph, sentence, or word of this Ordinance be rendered or declared invalid by any final court action in a court of competent jurisdiction, or by reason of any preemptive legislation, the remaining provision, sections, paragraphs, sentences, and words of this Ordinance shall remain in full force and effect. Section 7. The City Clerk shall certify to the adoption of this Ordinance and shall cause the same to be posted in three (3) public places within the City of Diamond Bar within fifteen (15) days after its passage in the manner prescribed by Resolution NO. 89-6. ADOPTED AND APPROVED THIS day of , 1992. Mayor I, LYNDA BURGESS, City Clerk of the City of Diamond Bar, do hereby certify that the foregoing Ordinance was introduced at a regular meeting of the City Council of the City of Diamond Bar held on the revised 12/26/91 11 day of meeting of the City of , 1992, and was finally passed at a regular Council of the City of Diamond held on the day 1992 by the following vote: reviscd 12/26/91 12 r RESOLUTION NO. 92-2 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF DIAMOND BAR RECOMMENDING THAT THE COUNCIL OF THE CITY OF DIAMOND BAR APPROVE THE REPEAL OF THE OAK TREE PERMIT PROCESS AND THE REPLACEMENT OF SUCH WITH A TREE PRESERVATION ORDINANCE. A. Recitals. (i) The City of Diamond Bar is recognized for its unique and distinguished natural and improved physical environment. A major element of such physical environment is the varieties of trees, including naturally occurring stands of oak, walnut, scyamore and pepper trees. These trees value to the community is such that all reasonable efforts should be. undertaken to preserve and enhance them. Such measures must also Y be balanced against the circumstances which may require the removal, relocation or maintenance of such trees. (ii) The City of Diamond Bar presently is without adequate regulations which serve to foster the preservation of such trees while responding to the needs of owners of the properties on which such trees may be sited. (iii) The Planning Commission has extensively considered the issues related to a balanced tree preservation ordinance, and has, with the benefit of public input, developed a proposed tree preservation ordinance which it hereby recommends to the City Council for its review and adoption. (iv) All legal prerequisites to the adoption of this Resolution have occurred. 1 r f`' B. Resolution. NOW, THEREFORE, the Planning Commission of the City of Diamond Bar, California finds and resolves as follows: SECTION 1. In all respects as set forth in the Recitals, Part A, hereinabove. SECTION 2. That the Diamond Bar Planning Commission recommends that the Council of the City of Diamond Bar approve and adopt the proposed tree preservation ordinance attached hereto as Exhibit "1". SECTION 3. That the City of Diamond Bar is in the process of finalizing its draft General Plan and that, on the basis of such draft plan there is a reasonable probability that «:f the intent of this Ordinance will be consistent with the goals, policies and objectives of the ultimate General Plan. Further, there is little or no probability of substantial detriment to or interference with the ultimately adopted general plan if inconsistencies are ultimately present because the preservation of both the naturally occurring and introduced trees -will enhance the City and the environment which will be of benefit to the present and future community. Finally, this action is undertaken in conformance with all applicable laws. SECTION 4. The Planning Commission finds and determines that the ordinance proposed by this Resolution is categorically exempt from the requirements of the California Environmental Quality Act of 1970, as amended, and the Guidelines thereunder - promulgated pursuant to Section 15307 of Division 6 of 2 Title 14 of the California Code of Regulations. I, SECTION A. That the Secretary to the Planning Commission deliver this resolution to the City Clerk. ADOPTED AND APPROVED this 13th day of January, 1992. Chairman I, JAMES DESTEFANO, Secretary of the Planning Commission of the City of Diamond Bar, do hereby certify that the foregoing Resolution was introduced at a regular meeting of the Planning Commission of the City of Diamond Bar held on the 13th day of January, 1992, and was finally passed at a regular meeting of the Planning Commission of the City of Diamond Bar held on the 13th day of January, 1992, by the following vote: AYES: COUNCIL MEMBERS: GROTHE, HARMONY, FLAMENBAUM and SCHEY NOES: COUNCIL MEMBERS: None ABSENT: COUNCIL MEMBERS: MCBRIDE ABSTAINED: COUNCIL MEMBERS: None ATTEST: Secretary L\1011\RESOTREE\DB 6.7 3 MINUTES OF PLANNING COMMISSION MEETING JUNE 24, 1991 Draft Tree Preservation Ordinance PT/Ann Lungu addressed the Commission regarding a draft Tree Preservation Ordinance. The primary need is to determine to what extent the Commission would like this ordinance to establish the Policies for the City of Diamond Bar's tree preservation. Staff would appreciate comments and suggestions on the ordinance. VC/Harmony made the following suggestions for the Ordinance: the definition of multitrunk trees is unclear; there should be some special leeway to allow closer buildings within the drip line; nurseries should be included; the City should be involved in the certification of the diseased tree; the City Engineer should have to process a request at some level; Public Utility should not be given authority over Oak Tree/Heritage Tree without some review; the pruning % of the whole tree may be a more appropriate approach to regulating trimming; there should be a provision for allowing instances to chop tree tops, as well as trimming and pruning; the concepts of item G & H, under the Oak Tree/Heritage Tree Permit Application, needs clarification; there should be a longer time period to allow for an appeal; change "dangerous condition" to "eminent danger", under Emergency Waiver; clarify the difference between a horticulturist and an arborist; the responsibility for maintaining replacement trees should be 5 years; broaden the definition concerning the replacement of trees with the largest available tree; the Protection of Existing Trees during construction should include maintenance; and the Enforcement Officer should have code enforcement authority. Chair/Schey questioned the appropriateness of a blanket statement requiring Oak Trees/Heritage Trees to be replaced by the largest available tree. There needs to be more flexibility to deal with particular situations. C/MacBride would like to include, in the list of exceptions, a consideration for trees on private property that require topping to prevent damage to the existing structures to the property. He suggested being more selective on the definition of a Heritage Tree, with consideration of historic inferences. C/Lin stated that fencing, for the Protection of Trees, may not always be warranted. She suggested the statement should include "where necessary and feasible". STUDY SESSION: October 14, 1991 Zoning Code Amendment 91-5 (tree preservation) PT/Lungu addressed the Commission regarding the proposal to amend certain provisions of the Los Angeles County Code, as adopted by Diamond Bar, pertaining to Tree Preservation. In preparing the various drafts for the tree ordinance, research was done using sections of ordinances from the cities, indicated in the staff report, that seemed compatible with our community for our purpose and intent. It is suggested that the Commission address the following four main issues regarding the tree ordinance: the criteria to be used to identify trees to be preserved; the minimum lot size standards for activation of a tree preservation ordinance; the replacement ratio and size of replacement tree that would be appropriate for the City's tree preservation ordinance; and the City's desire to insure that a replacement tree will receive the proper care and maintenance for a designated period of time. It is recommended that the Commission direct staff to prepare a "final" ordinance with the conditions listed by staff. CD/DeStefano stated that DCA/Curley has suggested some clarifications of items in the tree ordinance. Staff will review these at the end of discussion on the four main issues. He suggested that the Commission begin discussion regarding the criteria to be utilized. Chair/Grothe indicated that the criteria, for the replacement of trees on single family properties, should not be such that it is difficult to enforce. C/Schey suggested that a 1:1 replacement ratio is sufficient on a single family residential lot. Chair/Grothe concurred that a 1:1 replacement ratio is adequate, as long as it pertains to only the trees in the preservation list, and not all types of trees. CD/DeStefano inquired if a 1:1 replacement ratio would be adequate in a situation where the tree removed was quite old. C/Schey responded that, in that situation, no tree could adequately replace it. Chair/Grothe stated that the 4:1 replacement ratio for the removal of a Heritage tree makes sense on a hillside development, but not within a single family residential yard. C/Harmony stated that the Pepper Tree should be added to the Heritage Tree list. VC/MacBride indicated the following concerns: the definition of a Heritage tree is much too broad; the problem of a developer choosing to pay the fine, rather than leave a cluster of trees, must be addressed; and the issue regarding public safety vs. the preservation of a tree included in the protective category, need be addressed. C/Schey suggested differentiating between a Heritage tree and a Significant tree. Heritage trees are indigenous trees like the Oak, Sycamore, Walnut, and Pepper. The Significant trees are those that have reached some significance due to maturity or historical value. Short of public safety, there should be absolute preservation for Heritage trees. CD/DeStefano stated he has suggested to Staff eliminating the term "Heritage Tree" because he felt the ordinance was simply a tree preservation ordinance beginning with whatever size, species or combination we choose to establish as the minimum tree which we desire to protect. During Staff's research it became apparent that there is no common definition as to what the term "heritage tree" or "significant tree" means. Chair/Grothe pointed out that the original intention of this ordinance was to try to save the majority of the tree groves mostly located in the undeveloped areas of town. Therefore, the care of trees, located on lots under a specified size, should be left to the discretion of the homeowner. The Public Hearing was declared open. Dan Buffington, residing at 2605 Indian Creek, emphasized the importance of preserving trees now for the future. Don Schad, residing at 1824 Shady Wood Rd., suggested that the concern for tree size, per lot, and tree types should be carefully considered by a group of arborists, perhaps from a local college. He explained that a Heritage tree is a tree that has been able to sustain itself through it's own natural environment. He also suggested that all the species be protected that have a uniqueness to them. C/Schey suggested that the general tree population should not be preserved until there's some reason to believe that it is being threatened. The native tree should be established as protected. CD/DeStefano reminded the Commission that staff needs specific direction regarding the four major criteria issues previously indicated by staff. VC/MacBride suggested defining Heritage trees and Significant trees separately. Heritage trees would include Oak, Sycamore, California Pepper, and Black Walnut. Significant trees are trees that have a definitive historical significance, have a factor of age, and are outstanding in it's own individual growth, per species. PD/DeStefano stated that the Commission needs to be more specific with their definition of a Significant tree. If the Commission is unable to define it now, staff can, with the Commission's approval, attempt to come up with a differentiation between Heritage trees and Significant trees, and return it back to the Commission in an ordinance format. He then suggested that the Commission discuss if they want to differentiate any replacement value to the Heritage tree, the Significant tree, and all others trees. C/Harmony inquired if the Commission is in concurrence that single family residential lots are exempt. VC/MacBride suggested that the four stated categories of a Heritage tree, plus the historic attributes of a given tree, as well as significant trees be placed in one category called "Heritage Trees", and exempting those problems which arise on single family residential lots of a certain size. Chair/Grothe suggested, and the Commission concurred on, the following: the four types of Heritage trees, Oak, California Pepper, Walnut, and Sycamore, are protected everywhere and can be removed only by permit; all other trees that exceed the 15' height, and 15" circumference criteria fall in the Significant tree category and require a permit if they are on nonresidential or undeveloped residential property; trees with documented historic significance require a permit; there is a 1:1 replacement ratio, for Heritage trees, on existing developed residential properties; there is a 4:1 replacement ratio for Significant trees on non residential or undeveloped properties; the replacement tree should be of an in-kind species; there should be a steep penalty for trees removed without a permit; the size of the replacement tree is to be determined per the City of La Verne graph; and anyone removing a tree should be required to place a bond for insuring maintenance of the replacement tree. CD/DeStefano pointed out those items in the draft tree ordinance that will need further clarification: the definition of a Heritage tree will be expanded, and the definition of "multi-trunk" and "stand" needs further clarification; the verbiage regarding "Routine Maintenance" will be moved to the Exception clause; verbiage will be added to the Exception clause requiring that a damaged tree, or diseased tree, be verified by a certified arborist; in the Tree Permit Application, we must assure that the plans indicate the existing and the proposed structures; the amount of photographs required must be clarified in the Tree Permit Application; the verbiage, of item F of the Tree Permit Application, will be changed to indicate that "the applicant may be required to provide..."; add in the Tree Permit Application a specified time period in which the director will give a forthcoming decision; there also needs to be a time period indicating when the Director's decision will be received regarding the Tree Pruning Permit, item B; the issue regarding public safety vs. convenience will be addressed in the pruning of a tree section; the word "unbalanced", written on page 6, will be better defined; under Emergency Waiver, defining the proper contacts will be better stated; the word "acceptable" will be changed to "approved" in the section Protection of Existing Trees, section A & B; the phrase "unless otherwise approved by the Director" will be added to subsection E, of Protecting Existing Trees; and the last paragraph of the section Enforcement, will be removed. VC/MacBride, concerned with developers that may inadvertently or intentionally remove trees, suggested that instead of imposing a penalty, require that the trees be replaced in-kind and maintained. DCA/Curley stated that if a tree is removed, accidently or otherwise, the developer could be asked to stop the project, or meet the conditions that have been established. There are ways to reach the developer. Don Schad suggested that the required period of maintenance be extended from three years to five years. The Commission concurred with Don Schad's suggestion to extend the period of maintenance to five years. Chair/Grothe, concerned with the administrative burden on staff for enforcement, suggested that the bond requirement for a single tree on a single residence be excluded. DCA/Curley suggested, and the Commission concurred, to use a lien process rather than requesting a deposit or bond up front. The Public Hearing was declared closed. As directed by the Commission staff will renotice the Public Hearing when the ordinance is ready to be brought back to the Commission. Motion was made by VC/MacBride, seconded by C/Harmony and CARRIED UNANIMOUSLY to request staff to bring the ordinance back to the Commission the first meeting in December of 1991. Minutes of Planning Commission Meeting August 12, 1992 Preliminary Draft Tree Preservation Ordinance ZCA 91-3 PT/Lungu addressed the Commission regarding the second draft of the tree preservation ordinance. Comments from the Commission are requested. The next time the Commission meets to discuss this topic, it will be in ordinance form, and a public hearing. VC/MacBride made the following comments: Under Purpose, amend the phrase "as well as defined" to "definitive of"; under Intent and Applicability, the ordinance should pertain to both public and private property; and page 3, under Exception C, include shrubs, and add the wording "... necessary to keep street and sidewalk easements clear of obstruction..." C/Schey requested that the syntax "shall mean", "mean", etc. be eliminated from the Definition section. He also stated that defining a Heritage Tree, simply by size, seems to be an overly broad definition. VC/MacBride requested staff to review the item, possibly with Don Schad, and reword it. Following discussion, C/Schey suggested that the Significant Tree and the Heritage Tree be differentiated. The Heritage Tree can have the full review it is warranted, and the Significant Tree have at least some review. C/Harmony made the following comments: Under Diseased Trees, staff should include some reference to insect infestation, as well as wording indicating "and others inflicted by, but not limited to."; he indicated concern regarding the 2 inch guideline referred to in the Routine Maintenance section and Pruning Permit section; in reference to the removal or relocation of oak trees or heritage trees, some significant tree removal should remain in the purview of the Planning Commission and the Council; and on page 7, item E, replacement trees should be maintained for a period of five years. C/Schey discussed item E, page 5, regarding the enforcement of replacement trees. A warranty period of 3 to 5 years is a long time, and often the developer has become unavailable. He suggested that language be included in the content that the applicant, permittee, or successor, whoever is responsible for that property when the tree is removed, is responsible for the replacement trees. C/Harmony suggested that a provision for paying the City the appraised value of the lost tree, if it cannot be replaced, be included with the tree replacement clause. C/Schey, noting that often times developers view the fines as a more desirable option, requested staff to review the provision in Claremont, which carries a heavier penalty. C/Lin inquired how the capabilities of tree specialists are differentiated. PT/Lungu stated that they must have proof of qualifications and references of past work. VC/MacBride requested staff to determine if there is a California requirement that establishes standards which indicates that the specialist is licensed, bonded, or certified. Chair/Grothe noted that, in the replacement of trees, quantity is not discussed. Understanding that tree sizes and types must be varied, he cautioned that unless there is a minimum replacement number indicated, some developers will manage to elude the specifications. PD/DeStefano stated that a section will be added pertaining to the replacement ratio, and the issues pertaining to the size of the replacement trees. He then stated that, with the Commission's comments, staff will prepare the document in full ordinance format, and establish a public hearing process for the Commission's recommendation to the City Council. MINUTES OF PLANNING COMMISSION MEETING DECEMBER 9, 1992 PUBLIC HEARING: Zoning Code Amendment 91-5 PT/Lungu reported that the Commission, at the October 14th meeting, directed staff to have the draft tree preservation ordinance reformatted for the December 9th meeting. Staff recommended that the Commission adopt a Resolution recommending that the City Council approve the Tree Preservation Ordinance. VC/MacBride, concerned that a situation may arise whereas a developer may choose to pay the fine for destroying a forest of trees rather than hold up development, requested that there be definitive language in the ordinance indicating that there is an enormous penalty for such a situation. The intent of such language would be to influence the developers to think long and hard before cutting down a forest of trees. C/Flamenbaum noted that section 5, of the ordinance, under Tagging, already indicates that the City would have a Civil right to sue for abatement of a nuisance, and damages that result. C/Harmony, concurring with VC/MacBride, stated that additional language, emphasizing the desires of the Commission, helps establish policy for future administrations and city attorneys to pursue these cases when they happen. DCA/Curley stated that provisions in nuisance abatement type ordinance is already structured, in essence, to say: "The City Attorney's office is hereby directed to institute proceedings." Wording to the effect, "... and shall seek to obtain remedial measures, including restitution or tree replacement.", could be added to the provision and could be appropriately placed in Section 5, of the ordinance, to amplify the intent. However, the overall legal impact may not be effective. He reminded the Commission that, procedurally, the Council must first authorize, and direct any and all litigation to proceed. C/Schey suggested, and DCA/Curley concurred, that it may be more appropriate to place a policy statement, in the beginning of the Ordinance, under the Purpose and Intent Section, indicating that it is the intent of the City to preserve these trees, and we will pursue to the greatest extent. VC/MacBride, in reference to the tree guidelines manual, inquired if a statement could be incorporated into the ordinance stating that each applicant, under this section, shall be furnished, by the City, with a copy of the guidelines. DCA/Curley stated that, since the City does not have certified arborists that can examine each individual tree and give instructions as to it's proper care, it is strongly advised that these guidelines are eliminated to avoid future potential liability. C/Schey inquired if it is the City Attorney's recommendation that the City leave the care and feeding of the trees as the responsibility of the owners, or responsible party, to keep them alive. The City would then intervene if the trees should die. DCA/Curley concurred. Chair/Grothe questioned why a disclaimer could not be placed in the ordinance, stating that the guidelines is just information gathered to help in caring fora tree, and is not the full direction of the City. CD/DeStefano suggested that the Commission may opt to send the guidelines to the City Council, with the understanding of the City Attorney's office's concerns, and including the Commission's comments, but ultimately letting the City Council decide whether or not the guidelines are an appropriate attachment to the ordinance. The Commission concurred. C/Schey, concerned with section 22.56.2080 Definition (J) of the ordinance, stated that, to his recollection, it was the Commission's intent to establish an ordinance that preserves all Oak, Sycamore, Walnut, and Pepper trees, regardless of size. There seems to be an inconsistency. Chair/Grothe stated that he was under the impression that there would be a provision exempting residential homeowners from the preservation provision. CD/DeStefano reminded the Commission that they had developed the criteria for the size of the tree appropriate for preservation, after discussion on the matrix presented by staff, which included information as to what some other cities in the immediate area were doing. The Public Hearing was declared open. Don Schad made the following comments: There are other significant trees based upon size and heritage, other than the four indicated trees, that should be considered for preservation; the height and circumference limit is bearable as stated in the Definition section (J).1, but he suggested adding the word "dominance" after the word "survival" to (J)3., page 3; a relocated tree should be given the same care and consideration as a brand new tree; there is not a specific chart on tree sizes; and pages 1 through 11, of the ordinance, does not identify dimensional sizes for tree replacement. The Public Hearing was declared closed. Chair/Grothe stated that he was under the impression that the draft tree ordinance referred to a chart of sizes and quantities regarding tree replacement. DCA/Curley suggested that there should be flexibility on tree replacement ratios because site sizes may vary, and the trees may or may not fit as directed. The replacement ratio is currently at the Director's discretion, so that he may analyze the site and either determine the rational replacement ratio, or refer it to the Commission. C/Flamenbaum suggested that section 22.56.2160 Tree Replacement Standards item A, should read, "... on the basis of the Tree Report.". Chair/Grothe stated that he would prefer the ordinance to include specific replacement quantities or sizes so that when the developer pulls a permit he is immediately made aware of the guidelines he must follow. C/Schey stated his concern that, the way the ordinance is written, all tree removal permits would come before the Director and would not come before the Commission unless it is under appeal. CD/DeStefano recommended that, in order to clarify that the Planning Commission should review not only the tree removal, but all other environmental aspects of a project at the time that they are reviewing the specific project, subsection E. should be added to section 22.56.2100 Permit Required, stating that, "The Director, in his/or her discretion, shall refer the decision to the Planning Commission in the event that such application is in conjunction with the discretionary approval over which the Planning Commission has jurisdiction.". C/Schey, regarding the drafting of the tree report, noted that a situation could arise whereas the impartiality of the arborist could be questioned. He suggested that the arborist be employed by the City to ensure that he/she has the City's, and the tree's, best interest at heart. DCA/Curley concurred that the present structure of the ordinance looks to the applicant to employ the arborist. It could be modified whereas the applicant up fronts the cost, and the City would then employ the arborist who would analyze the situation impartially. C/Harmony noted that there is no provision in the ordinance protecting heritage trees that are significant because of size, age, or historical event, other than the four trees indicated. DCA/Curley suggested that the Commission may consider separating cultural significant attributes, versus the broader environmental significance, and designating those attributes within a separate culturally significant ordinance. CD/DeStefano indicated that, at this point and time, staff needs specific direction from the Commission as to how the Commission wishes staff to proceed on this issue. It is difficult for staff to determine historical events recognized by the City. C/Harmony stated that the historical value can be certified by the Planning Commission and/or the City Council, or the historical committee being formed. He would like heritage trees protected in the ordinance. C/Flamenbaum suggested that the ordinance be approved, with the recommendations and corrections made. If the Commission desires historical items to be preserved, then a separate ordinance should be created. The Commission concurred. C/Harmony stated, for the record, omitting reference to heritage trees, within the tree ordinance, limits the scope of the ordinance, and is therefore, not a complete ordinance that way. C/Harmony, referring to the civil remedies, section 22.56.2180 Tagging subsection 5. , stated that it is not clear what kind of civil remedy the City would receive if the developer destroyed, for example, a 600 year old tree. There should be a clearly stated penalty that the developer will be responsible for replacing the tree, and that a neutral arbitrator will be utilized to appraise the tree, if needed. DCA/Curley recommended that the wording of subsection E not be altered. The provision gives full flexibility to pursue whatever remedy is deemed appropriate by the City Council. It is understood that the City would seek replacement or replacement costs. CD/DeStefano suggested that the Chair may wish to appoint a sub- committee, of the Commission, to work out the specific details and assist staff in bringing the matter back to the full Commission in January of 1992. C/Schey recommended that the subcommittee limit their discussion on the following two issues that remain unresolved: the delineations of the penalties; and the minimum replacement standard. C/Schey and VC/MacBride volunteered to be on the subcommittee. C/Schey recommended that the matter be continued to January 13th, with the subcommittee working with staff to reconcile these matters, and bringing it back to the Commission in final form on that date. The Commission concurred. VC/MacBride requested staff to appropriately revise section 22.56.2090 Exemptions subsection D. so that it is more clearly stated. Chair/Grothe called a recess at 9:35 P.M. The meeting was called back to order at 9:44 p.m. C/Flamenbaum suggested that the Commission recommend to the City Council to consider the establishment of an ordinance taking into account all historical items within the City confines. The Commission concurred. MINUTES OF PLANNING COMMISSION MEETING JANUARY 13, 1992 PT/Lungu reported that on December 9, 1991, at a noticed public hearing, staff presented a final draft tree preservation ordinance to the Commission for review. A subcommittee of two Planning Commissioners, C/Schey and VC/MacBride, were selected to deal with the issues of heritage trees, replacement standards, and civil remedies. PT/Lungu reviewed the decisions made by the subcommittee regarding the three issues, as indicated in the staff report. Staff recommended that the Commission adopt a Resolution, with additions resulting from the subcommittee meeting, recommending that the City Council approve the Tree Preservation Ordinance. Furthermore, it is recommended that the language, "The Director, in his/or her discretion, shall refer the decision to the Planning Commission in the event that such application is in conjunction with the discretionary approval over which the Planning Commission has jurisdiction.", should be inserted to subsection 22.56.2110 as a new addition after subsection H. CD/DeStefano explained that this addition would allow the Director to forward the application to the City Planning Commission for review. It is staff's opinion that applications for discretionary approval involving the removal of trees, should be reviewed by the Commission, including the removal of any Oak, Walnut, Sycamore, or Pepper trees. The Public Hearing was declared open. Don Schad complimented the Commission and staff on their job in developing the Tree Ordinance. The Public Hearing was declared closed. Motion was made by C/Schey, seconded by C/Harmony and CARRIED UNANIMOUSLY to approve the Ordinance as drafted, with the inclusion of the Director's discretion to send nondevelopment related permits to the Commission for their review, and the inclusion of provision mandating that tree removal permit that relate to development permits, under the Commission's discretion, be mandatorily brought with the balance of the package. Chair/Grothe called a recess at 9:25 p.m. The meeting was called back to order at 9:42 p.m. 8.7-035-u1 ilj 17; u); PART 16 - CHAPTER 22.56 OAK TREE PERMITS 22.56.2050 ESTABLISHED - PURPOSE. The oak tree permit is established (a) to recognize oak trees as significant historical, aesthetic and valuable ecological resources, and as one of the most picturesque trees in Los Angeles County, lending beauty and charm to the naturaland man-made landscape, enhancing the value of property, and the character of the communities in which they exist; and (b) to create favorable conditions for the preservation and propagation of this unique, threatened plant heritage,. particularly those trees classified as "heritage oak" trees, for the benefit of current and future residents of Los Angeles County. It is the intent of the oak tree permit to maintain and enhance the general health, safety and welfare by assisting in counteracting air pollution and in minimizing soil erosion and other related environ- mental damage. The oak tree permit is also intended to preserve and enhance property values by conserving and adding to the distinctive and unique aesthetic character of many areas of Los Angeles County, in which oak trees are indigenous. The stated objective of the Oak Tree Permit is to preserve and maintain as many healthy Oak trees in the development process. 22.56.2060 DAMAGING OR REMOVING OAK TREES PROHIBITED - PERMIT REQUIREMENTS.
