DATE: 11/20/00 TITLE : CHARLENE CIRCLE TREE STAFF: CARROLL RECOMMENDED ACTION : Accept the Tree Resource Conservation and Reforestation Plan at Charleen Circle. ITEM EXPLANATION : The over matured Tipuana tipu trees on Charleen Circle are causing infrastructure damages to City property and were scheduled for removal by the City's Tree Maintenance Division. Residents on Charleen Circle expressed their concerns that the arbitrary removal of all these trees at one time will affect their quality of life and the unique characteristics these trees offer to their neighborhood. To resolve this issue, an arborist consultant was retained to conduct a study and develop a tree management plan that requires the cooperation from both the City and residents on Charleen Circle. The end result is a Tree Resource Conservation and Reforestation Plan developed by the consultant (see Exhibit 1). The Plan requires the City to plant twelve 15-gallon Tipuana tipu trees adjacent to the existing over matured trees and three 15-gallon Tipuana tipu trees at three vacant plant sites. One of the helve over matured trees is removed in the year 2000 followed by another tree removed every .;ee years until the last over matured tree is removed in 2043. By 2043, the fifteen trees planted in 2000 will be fully grown. To avoid future infrastructure damages and to ensure the residents continue receiving the benefits of these trees, the Plan will be implemented all over again. Two draft plans were submitted to residents on Charleen Circle for their review and comments. In addition, staff met with residents twice to review the Plan with them. Staff incorporated all the changes made by Charleen residents, and by the second draft, there were no objections to the Pian. Staff is recommending the Commission accept the attached Plan so that staff can begin implementation immediately.

Tree Resource Conservation and Reforestation at CHARLEEN CIRCLE c Prepared for: November 1999 The City of Carisbad Prepared by: Treeco Arborist 729 Oak Knoll Street Brea, CA 92821 714-990-5553 020 EXHIBIT 1 r Introduction Importance of the Community Forest to Charleen Circle Residents Trees are an important component of the Charleen Circle community environment and by extension important to the community forest of the City of Carlsbad. In addition to enhancing the quality of life the community's trees also moderate noise levels, cleanse pollutants from the air, produce oxygen and absorb carbon dioxide and other greenhouse gasses. Trees also provide significant economic benefits. The economic benefits of each tree to a communtty have been quantified at between $431 to $492 per tree, per year.' Real estate appraisers have found that neighborhoods with a healthy street tree population have substantially higher property values than similar neighborhoods without trees. Research by the U.S. Forest Service shows that trees comprise an average of 6 to 12 percent, and in some cases up to 20 percent, of the appraised value of residential property. Properly managed trees return overall benefits and value to the community far in excess of the time and money invested in them for planting, pruning, protection and removal. The residents of Charleen Circle have recognized these benefits and consistent with their strong commitment to conserve the valuable tree resource, they have determined to adopte a comprehensive community tree resource management plan. This plan started in 1999 with an inventory of trees on Charleen Circle, within the city right-of-way. The findings of the inventory establish a benchmark of conditions at a particular point in time. These findings are used to establish objectives for a management plan. Objectives are desires set in a time line. The objectives are placed into a document (a plan). The plan document outlines the ways and means for achieving the objectives by establishing the policies and procedures for planting and maintaining trees. A specific management strategy is suggested in this plan. Successful implementation of the plan requires that City tree managers and residents of Charleen Circle work together to achieve the objectives. A tree maintenance schedule beginning in 2000 has been provided with the suggested plan. This schedule may be modified as the City tree managers and residents reevaluate the objectives of the plan over time. City tree managers and the residents will need to schedule, track and evaluate work information to assure that the objectives are being met. Evaluation of progress is necessary for future planning. The management plan, as designed, is a dynamic document. The intent of this plan is to: 1) sustain a healthy tree resource, 2) increase long-term economic benefits to the residents of Charleen Circle, and 3) improve the health, safety and welfare of the tree resource at Charleen Circle in the present and future. On Balance, Weighmg the Benefits and Costs of Urban Trees, Cheryl Kollins, et.al. 1991 Charleen Circle, City of Carlsbad Community Forest Management Plan I999 page 1 of IO by TreeCo Arborist Inc. Brea, CA - Stephen G. Holcornb ISA#WC-O183 Maior findings of the tree inventorv of 1999: r 0 A listing of trees with their condition rating and contribution to hardscape damages as of September 1999 is found in Table 1, page 6. 0 Based on the findings of the tree resource inventory the current minimum landscape value of the tree resource at Charleen Circle is estimated at $54,000. There is an estimated minimum additional value in annual environmental benefits of $5,000 per year. Currently there are 13 valid tree sites occupied by 12 trees and four (4) vacant planting sites. There are two sites currently occupied by trees, which are not valid planting sites (NVS) where no tree should be planted. These sites have been fragmented by the construction of second driveways at certain residences. However changes can be made to validate these site. Because all existing trees are either mature or over-mature we project a net loss in actual tree value over the next 10 years in both property value and ecological benefits. This loss will be reversed by the year 201 0 when property values will begin to increase as the short term rotation planting begins to show its effects. The value of the community forest will stabilize at an estimated $75,000 (adjusted for inflation) for as long as the plan is implemented or until more tree planting sites can be created (each additional tree site will add approximately $5,000 of tree value for the median age tree). 0 Tree age distribution is very low. All trees are approximately the same age and all are over- mature. Over-mature is defined as a tree which has more static than dynamic wood mass. Over-mature trees tend to reach equilibrium of energy and mass by shedding large parts such as branches. Species diversity distribution is zero because the only species is Tipuana fipu. This species will also be the replacement species in all plantings. 0 Most of the trees are in fair to good condition with the exception of two trees at 2035 Charleen Circle which are in fair-poor condition, These trees have been given the earliest possible removal dates. One tree has a hazardous condition. 0 Trunk Diameter, Tree Heiaht and Tree Canow Spread (shade cover) frequency show that the tree population is dominated by mature and over-mature trees. The current risk caused by this condition is the short term decline of all of the trees during the same decade. This would necessitate clear-cutting and replacement with small trees. This process would rob the residents of the value of the resource during the following decade-and-a-half. 0 Scheduled short-term tree rotation as recommended by this plan is given in Table 2. The implementation phase of the management plan begins by scheduling trees for appropriate planting or multi-sites, followed by tree removals as based on these recommendations and objectives defined by the management plan. The plan contains a recommended short-term tree rotation schedule for the first short-term rotation (45 years) of the plan, Given that there is a maximum of 15 valid tree sites, a 2% short term rotation would be equivalent to removal of one tree every three years (a 45 year short term rotation). If a lesser number of tree sites are approved for this plan the short term rotation will be adjusted by the final number of sites. Charleen Circle, City of Carlsbad Community Forest Management Plan 1999 page 2 of 10 by TreeCo Arborist Inc. Brea, CA-Stephen G. Holcomb ISAMC-0183 022 h Community Tree Resource Management Plan r Goals, objectives, policies and procedures have been established for this plan. "Goals" are defined as general intentions or philosophies that reflect the hope of the community relative to conservation of its tree resources. "Objectives" are specific targets, or measurable timeline events, to achieve stated goals. "Policies" are guidelines for daily operations and procedures are the specifications for maintenance. The Community Tree Resource Management Plan contains objectives consistent with achieving goals and policies consistent with meeting objectives. It is intended that this plan be dynamic and that appropriate revisions be made. Objectives that work should be repeated and objectives that do not work should be eliminated or replaced. Goals The following general goals have been selected for the conservation of the tree resource at Charleen Circle. Establish and maintain optimal tree cover. Maintain trees in a safe and healthy condition through good cultural practices. Conserve the tree canopy by sustaining an optimal tree age diversity. Promote conservation of tree resources at Charleen Circle and assist other areas of the community in the City of Carlsbad to promote conservation of their tree resources both public and private. Select, situate and maintain trees to minimize tree hazards, public nuisance, hardscape damage and maintenance costs. Centralize tree management and authority to assure the enforcement of the tree policies developed for Charleen Circle. Foster resident stewardship of trees on Charleen Circle and encourage proper tree maintenance of privately owned trees. Promote efficient and cost-effective maintenance of the Charleen Circle tree resource. Facilitate the resolution of tree related conflicts between residents. Charleen Circle, City of Carlsbad Community Forest Management Plan 1999 page 3 of 10 by TreeCo Arborist Inc. Brea, CA - Stephen G. Holcomb ISAWC-0183 023 h cc Objectives Objectives (specific targets) for improving the community forest have been selected for time periods up to 45 years. The objectives should be reviewed every five years and adjusted for maximum benefit to achieve the intention of the goal statements. It may be necessary to redefine objectives or to lengthen or shorten their timelines. 0 Population Density: As of September1 999 the Community contained 12 trees, 3 vacant planting sites and 2 non-valid tree sites. One site may be divided into two sites giving a maximum site potential of 15 valid tree sites. We suggest that the management plan establish an optimal minimum population density of 15 tree sites on Charleen Circle. Because there are a total of 11 multi-sites (where an existing tree will be replaced at a new location, allowing for the existing tree to serve as an interim tree while the replacement tree matures) a total of 25 trees will exist for a brief period by 2025 all existing trees will be replaced. Increasing the current population density will begin with the planting of 9 trees at rnulti-sites in the year 2000. 0 Tree Species Diversity: The tree population currently consists of one tree species. The objective of the management plan is to keep this one species as the identifying tree on Charleen Circle. This objective has been achieved. To sustain it all trees planted or replanted as part of this plan will be Tipuana tipu. 0 Tree Age Diversity: Age diversity shall be the primary management strategy used to sustain a high quality tree resource on Charleen Circle in perpetuity. The recommended median tree age is set at 22.5 years and will be achieved by 2024. The oldest tree will be 45 year and the youngest tree will be one (tree age is determined for the date of planting not the physical age of the tree). A large percentage of young trees reduce the value of the landscape. A large percentage of old trees leads to increased maintenance costs and tree related hazards. It is the objective of the management plan to reach an age diversity of 20% (3) young, 67% (1 0) mature and 13% (2) high quality, over-mature trees within 25 years. Begin in the year 2000 and continue thereafter to remove 1 tree every three years (2%), and replant with Tipuana tipu. This will result in a median (half above and half below) tree age of 22.5 years. The oldest tree will be 45 years old and the youngest tree will be one year old. 0 Health: The current tree population is comprised of 10 (83.3%) trees in good condition and two (16.7%) in fair condition. There is one tree with a hazardous condition, which can be removed by pruning. It is the objective of the management plan that there be no dead or poor condition trees. The recommended removal and replacement program will achieve this objective by 2024. (Trees in poor condition will always be given highest priority for removal.) 0 Maintenance Practices: All tree pruning shall conform to the ANZl A-300 standards except where an interim tree is being crown reduced to make room for a young tree growing as a replacement in a multi-site by 2006. Charleen Circle, City of Carlsbad Community Forest Management Plan 1999 page 4 of 30 by TreeCo Arborist Inc. Brea, CA - Stephen G. Holcomb ISA MC-0183 824 r IMPLEMENTING THE PLAN PROCEDURES The condition of the community tree resource on Charleen Circle will be maintained to the highest standard attainable within a budget approved by the City of Carlsbad. The intention of this management plan is to establish, for each individual tree, a Routine Maintenance tree removal and replacement cycle and a tree pruning cycle consistent with street/landscape usage of the trees within the easement of the City of Carlsbad. To achieve these intention the following procedures shall be implemented. Tree Removal: The major problem of the community forest in 1999 is the number of over-mature trees and the lack of young trees. Because tree age diversity has been ignored all the trees are the same age and most of the trees should be removed within 15-21 years. To meet the objective for tree age diversity it will be necessary to remove a significant number of the current trees within 15-21 years. The adverse effect of this number of short-term removal will be off-set by creating multi-tree-sites and planting a large percentage of young trees and maintaining interim trees at all the multi-sites. Beginning in the year 2000 one tree will be scheduled for removal every three years. Priority for removal has been given to the tree with the poorest condition rating. Second priority will be given for other trees in fair condition. Third priority will be given to trees existing at “not-valid” tree sites. This process will continue until all the remove-noheplant trees are removed. Then the remaining “remove and replant” trees will be scheduled for removal and replacement. Tree Pruning: There are 3 tree pruning procedures: 1. 2. For interim trees the objective is to reduce the size of the existing tree to provide light and space for the replacement tree growing within the multi-site. This pruning should conform where practicable to ANSI A-300 “Crown Reduction” or “Crown Restoration” pruning. For permanent trees (trees planted after the year 2000) tree pruning shall conform to ANSI A-300 “Crown Cleaning.” Each tree will be pruned to remove dead or dying branches once every eight years. Due to the short rotation planting crown reduction should not be needed to control tree height. Some “Crown Raising” may be needed to maintain street clearance. Tree Plantinn: Beginning in 2000, 100% of the three (3) vacant planting sites will be planted to fill all the vacant sites. In addition, 13 trees will be planted in the multi-sites. In order to achieve the proper age diversity, some of the trees planted in 2000 will be removed before they reach their maximum age of 45 years. See Table 2 for the tree planting schedule through the first rotation. Younn Tree Maintenance: Young tree maintenance will include the removal of planting stakes and structural pruning to develop proper tree structure. These will be done a minimum of one year and a maximum of one-and-one-half years after planting. Young trees that cannot stand on their own after one-and-one-half years of staking shall be removed and replaced otherwise, they will grow to be large weak trees.

Holcornb ISA WC-0183 025 r Resolvinn Tree Related Issues between Residents of Charleen Circle: Upon adoption of this plan by consensus of the existing residents of Charteen Circle and the City of Carlsbad, tree related the City Parks and Recreation Commission using this plan, as a guide would resolve issues between residents of Charleen Circle. Conditions in 1999: Table 1 will be used as a benchmark to review the conditions existing at the time the plan was formulated. Measurement of success of the plan will be based on this information. In Table 1 Haz = Hazard, DBH = Trunk Diameter at Breast Height (4.5 feet above grade), Ht = Tree Height, C-S = Canopy Spread. Table 1 shows the Condition of the Tree resource as of September 1999. Tree condition is determined by the condition of the Trunk (T), branch structure (S), leaf canopy (C) and the presence of pests (P). The rating are given as a total of points: 13-15 points = good, 11-12 points = fair, 10 points or less = poor. Tree related damage to hardscape is given for the Curb (C), Pavement (P) and Driveway Approach (D). Damage is rated from zero (0) no damage to three (3) significant damage. Trees are listed in the order they appear in the photographic guide to the plan and in the order they would be viewed when walking the street starting from Donna Drive and viewing the trees on the right side first.

Note: The current tree site at 2030 F-I is a multi-site associated with 2034 F-1. There is no valid tree site at 2030 and it will be the only residence without a tree. It is possible to have a site at 2027 in a previously unplanted location. If the driveway approach is realigned at 2031 to give a minimum of 10 feet on each side of the tree-site F-2, to hardscape, site F-2 would become a multi-site.

II Charleen Circle, City of Carlsbad Community Forest Management Plan 1999 bv TreeCo Arborist Inc. Brea. CA - Steohen G. Holcornb ISA WC-0183 page 9 of 10 It h r r‘ To foster resident stewardship of trees on Charleen Circle: 1. No resident of Charleen Circle may appeal the planting of a valid tree site as defined in this plan, to the Parks and Recreation Commission or subsequently to the City Council requesting that such a valid tree site not be replanted. 2. Residents will reimburse the City for the difference in cost of larger replacement trees and any additional costs associated with the planting of a larger tree. 3. Citizens are encouraged to plant a tree of a larger size, within the City right-of-way, at their own expense, as stewards of the community tree resource, as long as the replacement tree conforms to this management plan, its objectives and policies.

Charleen Circle, City of Carlsbad Community Forest Management Plan 1999 page 10 of 10 by TreeCo Arborist Inc. Brea, CA - Stephen G. Holcomb ISA#WC-0183 h 3 r PHOTOGRAPHIC GUIDE TO THE PLAN INTRODUCTION: The photographs begin with the trees on the right as you enter Charleen Circle. The numbers refer to the position of the tree sites as determined by the address. These should conform to the City’s computerized tree inventory. Trees on Charleen Circle but having an identifying address on Donna Drive are side (S) trees. Trees on Charleen Circle having an identifying address on Charleen Circle are front (F) trees, Site numbers go in the direction of the ascending address. F-2 will be closer to Donna Dr. than F-I at a given address regardless of the side of the street it is on. All replacement trees will be replanted as far from the curb and as close to the limit of the City right-of-way as possible, while leaving the center line of the tree trunk within the City right-of-way. 3591 Donna Drive S-3. This is a multiple site, that is the existing site will be used as an interim site and a new tree will be planted near the location marked by the circled “X in the year 2000. Two trees will exist at the site but only one tree, the replacement is the actual Tree Site S-3. The original (interim) tree will be removed in 9 years. The plan schedules its removal in 2009. If the replacement tree does grows faster than expected the existing tree may be removed sooner. The existing tree will also be crown reduced or crown raised on the side of the replacement tree to give the small tree room to grow. This pruning should be done every two years in spring. In addition to planting the new tree and pruning the existing tree, the Mulberry tree on the private property at 3591 Donna Drive, marked with a white “X should be removed. This will give more space for the newly planted replacement tree. 3591 Donna Drive S-2. This is a multiple site. The replacement tree site will be planted in 2012 near the limit of the right of way and about five feet to the right of the present tree. The existing tree is scheduled for removal in 2024. The white line, at the arrow, shows the approximate limit of the City rightaf-way. The present tree will be pruned to reduce its limb structure toward the new tree every two years until its removal in 2024. The replacement tree will be about . e. If re lacement tree rowth is fast the resent tree can be removed sooner. 032 A r 3591 Donna Drive S-1. Road construction near this tree in 2000 did not severely impact roots. Due to the lean of the tree toward the residence, the tree should be inspected annually to determine if the root buttress is solid. This is an interim site. Because this is one of the smallest trees on the street and because of its high condition rating, it will be one of the last trees removed and replaced. This would suggest a planting of the real tree site in 2036 and the removal of the existing tree in 2048. The replant site is approximately indicated by the white arrow. 2034 Charleen Circle F-3. F-3 is a multiple site, that is the existing site will be used as an interim site and a new tree will be planted near the location marked by the "X in the year 2009. Two trees will exist at the site but only one tree, the replacement is the actual Tree Site F-3. The original (interim) tree will be removed in 10-15 years. The plan schedules its removal in 2021. If the replacement tree grows faster than expected the existing tree may be removed at an earlier date. The existing tree will also be crown reduced or crown raised on the side of the planted, to give the small tree r ' replacement tree, beginning at the time the replacement tree is -oom to grow. This pruning should be done every two years in spring. F Charleen Circle Tree Resource Conservation and Reforestation Plan-1999 033 ,,- 2034 Charleen Circle Fl 8 F2. F-2 at 2034 Charleen is not a multiple site. The existing site is vacant. F2 is approximately indicated by the red “X”. Site F1, approximately indicated by the white arrow is a multiple site associated with 2030 Charleen site F1. These vacant planting sites should be planted in 2000. The existing wall is within the easement and the palms will need to be removed as the new trees begin to develop. An alternative is to move the palm further back on the property. A root barrier may be used along the driveway approach to deflect roots and minimize the damage associated with tree roots. The site indicated by the white arrow is F-I at 2034 but it will be treated as a multi=site with F-1 at 2030. The existing tree at 2030 Charleen is scheduled for removal in 2012 and it will not be replaced. The new site at 2034 Charleen - F1 will replace the existing tree at 2030 Charleen - FI. 2034 Charleen F-I will be removed and replaced in the year 2030 and 2034 Charleen F-2 will be removed and replaced in the year 2042. 2030 Charleen Circle F1. This is actually a multiple site associated with site F-I at 2034 Charleen as given above for that address. For the purpose of the plan this site is identified as 2034 Charleen Circle, site FI. The red “X” indicates the approximate site where 2034 Charleen site F1 should be located. This site should be planted as soon as practicable (year 2000). The existing tree at 2034 Charleen F1 has a hazardous condition produced by a large branch that goes toward the property at 2030 Charleen. This branch has a large wound on the upper branch surface. Removal of the branch will eliminate the hazardous condition. The existing tree is scheduled for removal in 2012 with the replacement already growing at 2034 - F1. /c Charleen Circle Tree Resource Conservation and Reforestation Plan-1999 PHOTOGRAPHIC GUIDE Page 3 of 7 034 r 2010 Charleen Circle F1 8 2027 Charleen F-1.

One replacement tree will be planted at each address in 2000. The existing tree will be side trimmed and crown reduced to allow room for the newly planted trees to grow. This pruning will occur approximately every two years, reducing the size of the existing tree to allow space for the replacement tree. The existing tree is scheduled for removal in 2042 or earlier depending on the growth of the replacement trees. 2010 Charleen F-1 is scheduled for its first removal and replacement in the year 2039 with the first removal and replacement of 2027 Charleen F-I scheduled for the year 2045. ,.',. ,," . . . . 2031 Charleen Circle F1.

The original site has been fragmented by the addition of a second driveway at 2035 Charleen seen to the left of the tree. Significant damage has occurred to the driveway approach at 2031 Charleen, as seen to the right of the tree. Currently this site is to be eliminated by the removal of the existing tree in 2003. (Option; If the existing driveway approach can be moved so that the nearest edge is IO- 15 feet from the site, this site could become a multiple site. After the new driveway approach has been installed and new tree could be planted at the new site, in the center between the two driveways and as far from the curb as possible but still within the City's right-of-way. The existing tree would still be removed in 2003.) 2035 Charleen Circle F1. F-I is a multiple site. This tree will be removed and the appropriate site replanted in the year 2000.

Site F-2, is presently vacant. Its approximate location is identified by the red dot to the far left of the photograph. Site F-2 can be planted in the year 2000. This site is also a multi-site with the exception that the proposed planting site is shared with a tree on private property rather than with another street tree. If this site is planted, as the tree grows to maturity, the private tree (Yew Podocarpus) just behind the fence on the far left will have to be removed to give room to the new tree. As with all other tree removals of this type the Podocarpus can be slowly reduced in size while the replacement Tipuana grows to its full size. The existing tree is scheduled for removal in 2036. The existing tree wilt be crown raised and crown reduced to allow space for the replacement tree. This pruning should be scheduled every two years until the tree is removed.
