Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 1 Introduction and Overview Park Forestry was one of the components of the 2008 Clean and Safe Neighborhood Parks Bond program. Tree risk assessment was part of the Park Forestry effort. Glen Canyon Park was identified as having a high priority for tree risk assessment. In addition, one of the capital projects associated with the Bond was renovation of the Recreation Center and tennis courts at Glen Canyon. The City of San Francisco Recreation and Park Department requested that HortScience, Inc. assess the health and structural condition of trees, evaluate the risk posed by the trees, review proposed project plans and provide recommendations for tree preservation. This report represents next phase of assessment and presents the following information for trees #2468 – 3105.

1. Evaluation of tree health and structural condition. 2. Assessment of the risk of tree failure. 3. Evaluation of impacts from the proposed bond project. 4. Recommendations for action. 5. Guidelines for tree preservation.

Survey Methods Trees were surveyed in January 2012. Each tree was visually assessed from the ground. Trees with significant defects in structure and were considered a risk of falling into a use area were evaluated as follows:

1. Identifying the tree as to species. 2. Attaching a numerically coded metal tag on the trunk of each tree. 3. Recording the tree’s location on a map. 4. Measuring the trunk diameter at a point 54” above grade. 5. Evaluating the health and structural condition using a scale of 0 – 5:

5 - A healthy, vigorous tree, reasonably free of signs and symptoms of disease, with good structure and form typical of the species.

4 - Tree with slight decline in vigor, small amount of twig dieback, or minor structural defects that could be corrected.

3 - Tree with moderate vigor, moderate twig and small branch dieback, thinning of crown, poor leaf color, moderate structural defects that might be mitigated with regular care.

2 - Tree in decline, epicormic growth, extensive dieback of medium to large branches, significant structural defects that cannot be abated.

1 - Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage from epicormic shoots (secondary shoots that arise along the trunk and branches); extensive structural defects that cannot be abated.

0 – Tree is dead. 5. Comment on presence of defects in structure, insects or diseases and other

aspects of development. 6. Assess tree suitability for preservation as good, moderate or poor. 7. For trees that possessed a significant structural defect and were in proximity to a

use area: a. Identify the part of the tree most likely to fail and hit a target within the

next year. b. Identify the target(s) that would be impacted by that failure (e.g. street,

sidewalk, landscaping). c. Rate the potential risk using the method described in A Photographic

Guide to the Evaluation of Hazard Trees in Urban Areas. d. Identify arboricultural treatments to reduce the likelihood of failure and

improve tree health, structure, stability and longevity.

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 2 The scope of the survey was limited to trees in the following locations:

Adjacent to city streets. Adjacent to private property. Within and immediately adjacent to the proposed bond project area.

Description of Trees Six hundred twenty-seven (627) trees were evaluated, representing 15 species (Table 1). Essentially all of the surveyed trees had been planted as part of landscape development. Only the willow (#626) was native to the San Francisco area and appeared to be indigenous to the site.

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 3 Blue gum eucalyptus was the most frequently encountered species. With 423 trees, blue gum represented 67% of all trees evaluation. Blue gums were particularly dominant in the south and west sides of Glen Canyon and along O-Shaughnessy Blvd. As a general rule, blue gums were found in dense plantings (Photo 1). Photo 1. Blue gums #600 to 623 were part of a dense planting along O’Shaughnessy Blvd. Note extensive growth of vines along the trunks.

Condition of blue gums ranged from poor (215) to fair (145) to good (57) and excellent (6) (Photo 2). Trees varied from young and semi-mature in development. Trunk diameters ranged from 6” to 90”. Tree #625 was 90” in diameter; #1 was 89”. Twenty-two (22) blue gums were 50” or larger. In general, tree condition improved with trunk diameter. This is not surprising as small diameter trees were more likely to have been overtopped and suppressed. Photo 2. Located in the center of the park, near the pre-school facility, blue gum #625 was 90” in diameter and in fair condition.

Seventy-five (75) Monterey pines were present, located primarily on the east side of the property. Pines were mature in development with trunk diameters ranging from 8: to 42” (tree #44). Three Monterey pines (#41, 539 and 555) were dead. Overall condition was poor with 43 of 75 trees in that group (Photo 3). Only two pines, #501 and 502, were in excellent condition. Both were located at the end of Crags Court. Photo 3. Pines #41 – 57 were generally in poor condition with small high crowns and leaning trunks.

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 4 Forty-six (46) blackwood acacias were evaluated. This species was often found in conjunction with blue gum, particularly at the Bosworth St. parking area. Trunk diameters ranged from 6” to 31” (#516). Overall condition was poor (34 of 46 trees). Twenty-eight (28) Monterey cypresses were present, ranging in trunk diameter from 8” to 78” (#545). Condition varied widely from poor to excellent. Cypresses #113 and 599 were semi-mature in development and in excellent condition. There was also 18 Bailey’s acacia, 15 of which were in poor condition. Trunk diameters ranged from 7” to 14”. Almost all trees of this species were immediately adjacent to the Recreation Center. No other species was represented by more than 8 trees. Included in this group were:

8 river red gums were mature in development and in poor condition. 8 silver dollar gums ranging from 9” to 19” were present, concentrated in 7 Siberian elms in the southeast corner of the park, near Elk Street. 4 coast redwoods located behind residences on Turquoise Way. Trees were 21”

to 27” in diameter and in generally good condition. 3 Lawson’s cypress located on the south side of the Recreation Center. Tree

#69 was in excellent condition. 3 eucalyptus (species unknown) were present. Tree #3 and 594 were mature but

in poor condition. Tree #596 was in fair condition. Sydney golden wattle #60 was in fair condition and mature in development. Olive #70 was in fair condition and mature in development. Plum #74 was in poor condition.

Suitability for Preservation Trees that are preserved on development sites must be carefully selected to make sure that they may survive development impacts, adapt to a new environment and perform well in the landscape. Our goal is to identify trees that have the potential for long-term health, structural stability and longevity. Evaluation of suitability for preservation considers several factors:

Tree health Healthy, vigorous trees are better able to tolerate impacts such as root injury,

demolition of existing structures, changes in soil grade and moisture, and soil compaction than are non-vigorous trees.

Structural integrity

Trees with significant amounts of wood decay and other structural defects that cannot be corrected are likely to fail. Such trees should not be preserved in areas where damage to people or property is likely.

Species response

There is a wide variation in the response of individual species to construction impacts and changes in the environment. For example, olive and elm are relatively tolerant of construction impacts while eucalyptus and pines are sensitive.

Tree age and longevity

Old trees, while having significant emotional and aesthetic appeal, have limited physiological capacity to adjust to an altered environment. Young trees are better able to generate new tissue and respond to change.

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 5

Species invasiveness Species which spread across a site and displace desired vegetation are not always appropriate for retention. This is particularly true when indigenous species are displaced. Blackwood acacia, Bailey’s acacia, Sydney golden wattle and blue gum are considered invasive.

Each tree was rated for suitability for preservation based upon its age, health, structural condition and ability to safely coexist within a development environment (Table 2).

Table 2. Tree suitability for preservation. Glen Canyon Park. SF Recreation & Park Department. San Francisco CA.

Good Trees with good health and structural stability that have the potential for longevity at the site. Twelve (12) trees had good suitability for preservation including blue gums #18, 251, 299, 374, 422 and 565; coast redwood #544, Lawson’s cypress #69, Monterey cypress #113 and 599; and Monterey pine #501 and 502.

Moderate Trees in fair health and/or possessing structural defects that may be

abated with treatment. Trees in this category require more intense management and monitoring, and may have shorter life-spans than those in the “good” category. One hundred eight (108) trees were rated as having moderate suitability for preservation including 86 blue gums, 10 Monterey cypresses, 3 Monterey pines, 3 Siberian elms, Bailey’s acacia #567, blackwood acacia #237 and olive #70.

Poor Trees in poor health or possessing significant defects in structure

that cannot be abated with treatment. These trees can be expected to decline regardless of management. The species or individual tree may possess either characteristics that are undesirable in landscape settings or be unsuited for use areas. Five hundred four (504) trees were rated as having poor suitability for preservation including 331 blue gums, 67 Monterey pines, 45 blackwood acacias, 17 Bailey’s acacias, 16 Monterey cypresses, 8 river red gums and 8 silver dollar gums.

We consider trees with good suitability for preservation to be the best candidates for preservation. We do not recommend retention of trees with low suitability for preservation in areas where people or property will be present. Retention of trees with moderate suitability for preservation depends upon the intensity of proposed site changes.

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 6 Tree Risk Assessment Tree risk assessment is the systematic process of evaluating the potential for a tree or one of its parts to fail and, in so doing, injure people or damage property. All trees have the potential to fail. The degree of risk will vary with the size of the tree, type and location of the defect, tree species, and the nature of the target. Tree risk assessment involves three components:

1. a tree with the potential to fail, 2. an environment that may contribute to that failure, and 3. a person or object that would be injured or damaged (i.e. the target).

Tree Risk Rating System All of the surveyed trees were assessed using the procedure outlined in A Photographic Guide to the Evaluation of Hazard Trees in Urban Areas (N. Matheny & J. Clark 1994 (2nd edition. International Society of Arboriculture. Champaign IL). Following a visual inspection of tree health and structural condition, the part of the tree most likely fail within the next year was identified (e.g. branch, stem, or whole tree). The target that would be impacted by this part of the tree was then identified. The risk associated with the tree was evaluated using the following components:

Failure potential (4 points) - identifies the most likely failure and rates the likelihood that the structural defect(s) will result in failure within the next year. The part of the tree most likely to fail was assessed using the following scale:

1 - low - defects are minor (e.g. dieback of twigs, small wounds with good woundwood development)

2 - medium - defects are present and obvious (e.g. lean or bow that has developed over time, cavity encompassing 10-25% of the circumference of the stem, codominant stems without included bark)

3 - high - compounding and/or significant defects present (e.g. severe lean, cavity encompassing 30-50% of the circumference of the stem, multiple pruning wounds with decay along a branch)

4 - severe - defects are very severe (e.g. partial uprooting of leaning tree, decay conks along the main stem, cavity encompassing more than 50% of the stem)

Size of defective part (4 points) - rates the size of the part most likely to fail. Larger parts present a greater potential for damage. Therefore, the size of the failure affects the potential for injury or damage. The scoring system was as follows:

1 - most likely failure less than 6" in diameter 2 - most likely failure 6 - 18" in diameter 3 - most likely failure 18 - 30" in diameter 4 - most likely failure greater than 30" in diameter

Target rating (4 points) - rates the use and occupancy of the area that would be struck by the defective part. For the project areas, the following scoring was employed:

1 - occasional use (e.g. lawn or landscaped area) 2 - intermittent use (e.g. sidewalk, paths or sport facilities) 3 - frequent use (e.g. street parking) 4 - constant use (e.g. playground structure, high volume streets).

Page 9: Tree Assessment & Preservation Plan Glen Canyon Park · PDF fileone of the capital projects associated with the Bond was renovation of the Recreation ... Silver dollar gum Eucalyptus

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 7 The points in each category were added to obtain the overall hazard rating, with 3 being the minimum and 12 being the maximum value. Risk ranking = failure potential + size of defective part + target rating Among trees at Glen Canyon Park, the most likely failure included branch (318 trees), one stem (103) and the whole tree (206). Among potential targets were residences, 24), parking areas (38), sidewalks (99), city streets (53), and the ball field area (21). Two hundred fifty-six (256) trees had no specific target. Risk rankings of the surveyed trees ranged from 3 to 12 (see Attachments). Under a normal management regime, trees with the highest ranking would be abated first, followed in order of decreasing ratings. The City of San Francisco Recreation and Park Department abates risk for trees ranked 9 or greater, a total of 24 trees. Evaluation of Project Impacts Appropriate tree retention develops a practical match between the location and intensity of construction activities and the quality and health of trees. The results of the general and individual tree surveys were the reference points for tree condition and quality. Impacts from the proposed project were assessed using conceptual site plans. Plans depicted the general location and extent of proposed work. Grading, drainage, landscape and irrigation plans have not been finalized. The proposed project includes renovation of the Recreation Center, enlargement of children’s play area, repair and replacement of existing paving and general improvements to the landscape. The tennis courts would be relocated north of the current location. Impacts to trees could occur in a variety of ways. The staging area on Bosworth Street will be enlarged. The path from Bosworth Street to the Recreation Center will be enlarged and improved in order accommodate fire engines. First, demolition of existing infrastructure such as pavement may directly damage tree roots and crowns. Grading and other construction activities may also damage trees, through both direct mechanical injury and indirectly by altering drainage. Second, removal of trees in dense woodlands exposes those that remain to new conditions which may not be suitable for future growth. Based on my assessment of the proposed plan and evaluation of the trees, I estimate that approximately 250 of the 627 trees evaluated are either within or immediately adjacent to the proposed project area. Of this group, I recommend preservation of 60 trees and removal of 190 (Table 3):

3 trees noted as “preserve?” (#69, 192, 194) and 5 trees noted as “remove?” (#62, 63, 64, 65, 68). For these 8 trees, additional information on proposed site activities such as grading is needed in order to make final recommendation.

Among trees recommended for removal, 176 have poor suitability for

preservation. Near the Bosworth Street entrance, trees with poor suitability are largely blue gums. Around the Recreation Center are a number of blue gums and other species. North of the tennis courts, Monterey pines are in poor condition.

7 trees in good or fair (blue gum #30, 149, 156, 233), Siberian elm (#32, 34) and olive #70) are recommended for removal due to impacts from the proposed project.

17 trees recommended for preservation require specific pruning treatment.

Almost all trees are located along Bosworth St.

Blue gums #9 and 168 are recommended for removal as they have risk ratings of 9 or greater.

Based on my observations, the key elements of successful tree preservation during renovation of the park include:

1. Protect trees during all phases, from demolition and site clearing through landscape installation. Tree protection fencing should not be relocated, disturbed, or taken down without consulting the Project Arborist.

2. Review more detailed grading, drainage, construction and landscape plans so

that impacts from development activities can be evaluated in more detail.

3. Prepare irrigation plans to that impacts to trees are minimized. Tree Preservation Guidelines Glen Canyon Park will undergo a series of landscape improvements. Additional changes may be planned for the future. The following are recommendations for design and construction phases that will assist in successful tree preservation. Design recommendations

1. Verify the location and tag numbers of all trees within 25’ of the proposal construction areas. Include trunk locations and tag numbers on all plans.

2. Allow the Consulting Arborist to review all future project submittals including

grading, utility, drainage, irrigation, and landscape plans.

3. Prepare a site work plan which identifies access and haul routes, construction trailer and storage areas, etc.

4. Establish a TREE PROTECTION ZONE around each tree to be preserved. For

design purposes, the TREE PROTECTION ZONE shall be either the dripline or 1/3rd the tree height, whichever is greater. No grading, excavation, construction or storage of materials shall occur within that zone.

5. Install protection around all trees to be preserved. Where construction will be within 4’ of tree trunks, use hay bales instead of fencing. Any fencing shall be 6’ chain link with posts sunk into the ground. No entry is permitted into a tree protection zone without permission of the City’s project manager.

6. Route underground services including utilities, sub-drains, water or sewer around the TREE PROTECTION ZONE. Where encroachment cannot be avoided, special construction techniques such as hand digging or tunneling under roots shall be employed where necessary to minimize root injury.

7. Use only herbicides safe for use around trees and labeled for that use, even below pavement.

8. Design irrigation systems so that no trenching will occur within the TREE PROTECTION ZONE.

Page 20: Tree Assessment & Preservation Plan Glen Canyon Park · PDF fileone of the capital projects associated with the Bond was renovation of the Recreation ... Silver dollar gum Eucalyptus

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 18 Pre-construction and demolition treatments and recommendations

1. The demolition contractor shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection.

2. Trees to be removed shall be felled so as to fall away from TREE PROTECTION

ZONE and avoid pulling and breaking of roots of trees to remain. If roots are entwined, the consultant may require first severing the major woody root mass before extracting the trees, or grinding the stump below ground.

3. Trees to be retained may require pruning to provide clearance and/or correct

defects in structure. All pruning is to be performed by an ISA Certified Arborist or Certified Tree Worker and shall adhere to the latest editions of the ANSI Z133 and A300 standards as well as the ISA Best Management Practices for Tree Pruning. Pruning contractor shall have the C25/D61 license specification.

Tree protection during construction

1. Prior to beginning work, the contractors working in the vicinity of trees to be preserved are required to meet with the Consulting Arborist at the site to review all work procedures, access routes, storage areas and tree protection measures.

2. Any grading, construction, demolition or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist.

3. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied.

4. Fences have been erected to protect trees to be preserved. Fences are to remain until all site work has been completed. Fences may not be relocated or removed without permission of the City’s Project Manager.

5. Construction trailers, traffic and storage areas must remain outside fenced areas at all times.

6. No materials, equipment, spoil, waste or wash-out water may be deposited, stored, or parked within the TREE PROTECTION ZONE (fenced area).

7. Any additional tree pruning needed for clearance during construction must be performed by a qualified arborist and not by construction personnel.

8. All trees shall be irrigated on a schedule to be determined by the Consulting Arborist. Each irrigation shall wet the soil within the TREE PROTECTION ZONE to a depth of 30”.

9. Any roots damaged during grading or construction shall be exposed to sound

Tree Assessment & Preservation Plan HortScience, Inc. Glen Canyon Park, SF Recreation & Park Department Page 19 Summary and Recommendations The primary management challenges for the surveyed areas of Glen Canyon Park are related to mature trees located in dense plantings. Tree age is particularly problematic for Monterey pines which are largely at the end of their anticipated life-span of 80 to 100 years. As they age, pines become increasingly susceptible to insects like red turpentine beetle and diseases such as pine pitch canker. Species such as blackwood and Bailey’s acacia are likely to either die or fail as the age. In contrast, tree age is less critical in blue gum where growing conditions have stratified the population by size and condition. Blue gums in the area of the Recreation Center and along O’Shaughnessy Blvd. have been topped in the past, resulting in resprouts that are now large and often poorly attached to the trunk. Based on my observations, I recommend the following:

1. For the 250 trees in the area of the Recreation Center/tennis courts project, preserve 60 and remove 190 (Table 3).

2. For the 377 trees located elsewhere in the park:

a. Remove 12 trees with risk ratings of 9 or greater. b. Remove 25 trees that are in poor condition. c. Remove approximately 20 trees in the area of blue gum #592, located on

a very steep slope on the west side of O’Shaughnessy Blvd. d. Prune 9 trees with a risk rating of 9 or greater. e. Prune tress #292 and 441.

3. The Recreation & Park Department’s Trail Improvement project for Glen Canyon

Park will address pruning of blue gums #1 and 625.

4. Accelerate Park’s reforestation program. There are several opportunities for reforestation particularly near the Recreation Center.

In summary, the proposed project presents an opportunity to enhance the existing landscape by removing those trees which are either declining and/or at risk of falling, and replacing them with new trees that will benefit park users in the future. HortScience, Inc.
