Section Effective Date: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 5 DISEASE AND INSECT CONTROL 2. The Contractor shall exercise extreme care when excavating and working near existing utilities. The Contractor is responsible for correcting any damage to existing utilities for which the Contractor's operation is either the direct or indirect cause. The Contractor is required to call Underground Service Alert (USA) at (800) 227-2600 for marking of underground utilities prior to excavating. 1.04 Submittals The Contractor shall provide a copy of any spray report showing details of areas, times, chemicals, and rates of application. PART 2 MATERIALS 2.01 Chemicals A. Improved horticultural oils (such as Sunspray 6EP, or approved equal) or insecticide soaps (such as SaferpSoap, or approved equal) shall be the first chemicals of choice as they are among the least toxic materials to animals. When using these chemicals, only plants with greater than control threshold levels of pests shall be sprayed. This will avoid eliminating populations of beneficial insects. B. The toxicity of pesticides is expressed as LD50 (Lethal Dose). The lower the LD50, the more toxic the chemical. Generally, chemicals with an LD50 of 500 and above are considered quite safe. C. Highly selective pesticides with minimal residual properties shall be used, and broad-spectrum, long residual materials shall be avoided where possible. D. The noxious weed, disease, and pest control methods may include any combination of the following: 1. Pre-emergent herbicide application 2. Post-emergent herbicide application 3. Mechanical cultivation and disposal 4. Weeding or snowing 5. Chemical growth regulators 6. Tree injection 7. Aquatic herbicide application 8. Trap and release techniques 9. Poison baiting 10. Debris or food source removal Section Effective Date: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 6 DISEASE AND INSECT CONTROL 11. Water jetting 12. Insecticide, fungicide, rodenticide, or other pesticide application 13. Verdant and/or dormant spraying 14. Repeated control methods as necessary 15. Use of insect predators 16. Any other procedure recommended by the arborist, pest control advisor, or required by the County E. Under no circumstances shall agricultural chemicals be allowed to contaminate any open waterways or storm drain networks. The application rates shall not exceed the manufacturer's recommendations or be applied in a manner inconsistent with the label or pest control advisor's written recommendations, and any spilled material shall be cleaned up immedately and completely. 2.02 Tools All tools used in the management of pests and diseases shall be properly cleaned and sterilized to prevent the spreading of any pest or contageous disease. PART 3 EXECUTION 3.01 Monitoring A. Plant materials shall be periodically inspected by personnel trained in host and pest identification, biology, and management so that control actions can be defined. In general, monitoring shall occur monthly through the growing season (March through October). Where key pests are known to be troublesome on specific plant species ("hot spots"), monitoring should be timed according to the biological cycles of the pest. For example, where there is a history of scale infestation, monitor weekly during the late spring for crawler emergence. Key plants,key pests, and treatment options are provided in: Cooperative Extension University of California, Division of Agriculture and Natural Resources, Arthur H. McCain, Foliage and Branch Diseases of Landscape Trees (UC Leaflet 2616). B. During monitoring,the following tasks shall be performed by the Contractor: 1. Identify any pests present. 2. In the absence of pests, note any plant symptoms. 3. Assess pest population and stage of growth. Section Effective Bate: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 7 DISEASE AND INSECT CONTROL 4. Determine which sampling techniques are appropriate for the situation (e.g. trapping devices, pheromones, sticky tape). 5. Note existing or previous environmental conditions that influence pest development. 6. Evaluate degree of existing and potential injury to plant. 7. Evaluate population levels of predators and parasitoids on the pest. 8. Determine frequency of future monitoring needed based on the pest present and stage of development. 3.42 Treatment A. Disease and insect control programs shall follow a "least toxic" treatment plan to minimize negative impacts to the environment and landscape users. B. Pest problems shall be treated by undertaking the following steps: 1. Accurately identify the pest and host. 2. Schedule monitoring to coincide with pest biology. 3. Assess the extent of damage to the plant or degree of nuisance to the public. 4. Evaluate management options. a. Improve cultural conditions for plant. Approaches include irrigating according to plant needs, providing moderate fertilization when needed, mulching, and ensuring adequate soil drainage. b. Evaluate possible mechanical controls. Approaches include pruning, which removes weak and dead wood that are potential brooding sites of boring insects. Thinning out dense crowns can reduce certain leaf diseases such as anthracnose and powdery mildew and increases spray penetration. Plant removal is also an option if the plant is severely damaged. c. Evaluate possible biological controls. Section Effective Date: March 1,2004 r CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 8 DISEASE AND INSECT CONTROL Natural enemies include organisms that feed on pests (predators), parasitic organisms to the pests (parasitoids), or displace the pests with other organisms (competitors). When monitoring, assess present and potential plant pests and their natural enemies. d. Evaluate possible chemical controls. This approach shall only be taken after other options (cultural, mechanical, and biological) have been explored and exasperated. Where pest populations cannot be adequately controlled below threshold levels, targeted single applications of narrow-range chemicals specific to the pest, and with low toxicity to animals, may be applied. 5. Apply appropriate, "least toxic" treatments identified in.Part 2, Materials. 6. Apply all treatments according to the manufacturer's directions. 7. Inspect following a treatment to reassess pest populations. 8. Apply additional treatments if necessary. The timing and method of application shall be designed to maximize pesticide effectiveness and minimize adverse reactions and should take the following into account: a. Chemicals to control disease are usually most effective when applied as protectants before the disease organism invades the plant. b. Contact and systemic herbicides are most effective when applied while weeds are small. c. Pre-emergent herbicides should be applied before weed seeds germinate. d. Insecticide applications shall be timed to coincide with the most vulnerable part of the pest's life cycle. e. Soil, trunk, and root injections rather than spraying shall be done in areas close to homes and in areas used by people and pets. 9. Identify specific plantings as "hot spots" that require monitoring specific to the pest encountered. 10. All tools used in the management of pests and diseases shall be properly cleaned and sterilized to prevent the spreading of any pest or contageous disease.

PART 2 PRODUCTS AND MATERIALS None Specified. PART 3 EXECUTION 3.01 Tree Removal A. The Contractor shall obtain proper authorization and/or permits from the County prior to undertaking any tree removal work. Section Effective: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 5 TREE REMOVAL AND TRANSPLANTING B. The Contractor shall initiate the removal process when a hazardous condition exists due to an old, damaged, or diseased tree. C. In general, trees shall be replaced in-kind, however, the Contractor shall assess the need for removal and replant accordingly. For example, should conditions exist that would prevent the success of an in-kind replacement, a more appropriate species should be planted. The Contractor shall make recommendations for alternative species and shall not make any planting changes prior to County approval. I. Depending on the size of the tree, its relationship to adjacent trees, structures, or overhead lines, and the configuration of branches, the tree may need to be removed in segments. The method of tree removal shall be determined in consultation with the County. 2. Tree stumps shall be removed. In general planting areas, removal may be accomplished by grinding the tree stump to a depth of IS inches below grade. Where a replacement tree is proposed in the same location or a structure or paving is proposed, the tree stump shall be excavated to a minimum depth of 3 feet or as indicated in the geotechnical report for the structure or paving. 3. The Contractor shall remove all debris from site. Disposal of all materials, especially of diseased or infested trees, shall be done in accc►rdance with all applicable laws, codes, and regulations. 4. In the case of disease, the Contractor shall monitor tree disposal to ensure the disease is not spread. All tools in contact with diseased areas shall be sterilized to prevent further outbreaks. 5. The Contractor shall backfill tree stump pits with soil and fine grade the area to match the existing grade. 3.02 Tree Transplanting A.

The Contractor shall contact the County to make alternate arrangements should the Contractor not be able to meet this deadline. D. The Contractor shall avoid undertaking transplants during summer months, except under extraneous circumstances and as directed by the County. 3.03 Selecting Trees for Transplanting A. The Contractor shall determine species and specimens suitable for transplanting in consultation with the County. The following is generally recognized by the County: 1. Trees suitable for transplanting include, but are not limited to: a. Ash (Fraxinus sp.) b. Locust (Robinia sp.) c. Elm(Ulmus sp.) d. Hackberry (Celtis sp.) e. Sycamore, London plane (Plataus sp.) f. Poplar(Populus sp.) g. Willow(Salix sp.) h. Coast live oak(Quercus agrifolia) i. Crabapple (Malus sp.) j. Maple (Acer sp., except A. rubrum)) k. Pear(Pyres calleryana cvs.) 1.

Walnut (Juglans sp.) c. Oaks (Quercus sp., except Q. agrifal ia) d. California bay (Umbellularia calif rnica) e. Magnolia (Magnolia sp.) f. Sweet gum (Liquidambar styraciva) g. Tulip tree (Liriodendron tulipifera) h. Monterey pine (Pinus radiata) Section Effective: March 1, 2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 7 TREE REMOVAL AND TRANSPLANTING B. The Contractor shall ensure the tree size is appropriate for transplanting. Small plants transplant more successfully than large plants, and are significantly less expensive to dig and move. The larger the plant, the larger the root mass that mast be dug. As a general guide, the rootball should be about 10 inch diameter for each inch of trunk diameter. An arborist specializing in transplanting mature trees shall be consulted. C. Only healthy, structurally sound, and attractive plants that are suitable for the new environment shall be transplanted. The Contractor shall only transplant trees that meet the following criteria: 1. Generally symmetric with a well-formed crown. 2. Good foliage size, density, and color for the species. 3. Formal annual growth for species. 4. Central trunk with scaffold branches distributed radially and vertically around trunk. 5. Trunk and major branches free of wounds, decay, and cavities. 6. The plant is free of all significant diseases or pests that cannot be controlled (e.g. borers,bark beetles, psyllids, canker diseases, root rot, fire blight, etc.). D. The Contractor shall avoid transplanting trees exhibiting the following characteristics: 1. Plants with asymmetrical or unattractive crowns. 2. Plants with yellow, small, or sparse foliage for the species. 3. Leaning trees. 4. Plants with dead twigs or branches throughout the crown. 5. Trees with codominant (forked) trunks or with weak attachments of scaffold branches (V-shaped, crowded, etc.). 6. Trees girdled by staking ties or other constrictions. Section Effective: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 8 TREE REMOVAL AND TRANSPLANTING 7. Bark or scaffold branch injuries encompassing more than 25% of circumference. 8. Plants with conks or mushrooms on the trunk, branches, or around the root crown. E. The Contractor shall assess the following site characteristics: 1. Conditions of present tree site. a. Site conditions that affect root development and access to the tree shall be considered. b. Slope generally shall not exceed 10%. If tree is on a slight slope, it shall be planted at the same slope on the new site. c. The site soil shall generally be at least 3 feet deep for trees to have developed a root system that can be adequately dug. Excessively rocky and shallow soils may not allow transplanting. d. Adequate clearance around individual plants to be dug and transported shall be provided to make room for large equipment required for transplanting. 2. Characteristics of the proposed site. a. The conditions at the new site shall be conducive to the species that are being transplanted. b. A plant requiring acidic soils shall not be transplanted into an alkaline or calcareous soil and vice-versa. c. A plant requiring good drainage shall not be transplanted into an area with poorly drained clay soil, or at the toe of a slope or in a Swale in a frequently irrigated planting area. d. A tree grown in a sheltered or partially shaded location shall not be transplanted to an area with exposed, windy, or reflected heat conditions. F. Soil tests shall be performed to assess transplant site conditions. A site survey should evaluate soil depth, slope, aspect, microclimate, and wind and sun exposure. Section Effective: March 1,2004 F-1 AAL CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 9 TREE REMOVAL AND TRANSPLANTING G. Most transplanted trees have large rootballs and canopies and therefore need more planting space. The planting site shall allow for the transplanted rootball plus plenty of room for growth. H. If the new planting site is on a slope, a level area at least the diameter of the rootball shall be created on the slope. A wall may be required at the back of the planting area to retain the slope. I. Those contemplating transplanting a tree shall analyze the value of the tree and its ability to survive and perform well in the newly designated area, versus replacing the tree with younger container grown trees. 3.04 Mechanical Tree Spade Method The mechanical tree spade method is most suitable for transplanting a few trees a short distance, where they can be placed directly in the ground. The following procedures shall be followed when transplanting by the mechanical tree spade method. A. Select the appropriate tree spade according to the size of the tree. B. Prepare the tree for transplanting by irrigating several days before the transplant date to ensure soil is moist but not saturated and prune as needed to provide adequate access for the spade. C. Prepare the transplanting site by clearing 10 feet -15 feet around each tree (depending on the spade size) and a 7 foot-13 foot wide access path. D. Protect any trees that are to remain on the site from inadvertent damage by transplanting operations. Place fencing, barricades, weight dispersing materials, etc. as needed. E. Prepare the planting site by digging a plant pit twice as wide as the rootball and 6 inches deeper than the height of the rootball to allow for any settling. The spade may be used to dig the hole. Rough up the sides of the hole with a shovel to disrupt any glazing. F. Determine transporting route and ensure there is adequate clearance for safe passage past utility lines, overpasses, vegetation, and other possible obstructions. G. Only use sharp tree spade blades. H. Place the spade around the tree and insert each blade in sequence until all blades are fully inserted and completely surround the plant rootball. Section Effective: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Wage 10 TREE REMOVAL AND TRA.NSPLA'tiITING I. Lift the tree out of the ground and tip the tree forward into a transporting position. J. Tie down and tarp the tree crown to protect it from excessive moisture loss. Transport to new location. Ensure protection of the rootball. It may also be necessary to wrap the rootball to prevent excess soil loss. K. Carefully transport the tree to the new site location. L. Protect the surrounding soil from compaction by placing plywood or 6 inches of wood chip mulch beneath the wheels of the equipment. M. Place the tree in the new plant pit. Ensure the trunk is straight and plumb. N. When the blades are extracted, force a slurry mixture of soil and water into the voids around the rootball. U. Do not place site soil on top of the rootball. P. Do not apply vitamin B 1 or other"transplant shock" products. Q. Stake or guy the tree. Build a 6-inch berm to enclose the rootball. R. Apply mulch to the soil surface within the berm and irrigate thoroughly. S. Establish and execute a post-transplanting maintenance program. Refer to 3.06, Maintenance of Transplanted Trees. 3.05 Boxing Method A. Boxing shall be the preferred method of transplanting larger trees when they must be held for several months. B. Prepare the tree for transplanting by irrigating several days before the transplant date to ensure soil is moist but not saturated and prune as needed to provide digging access. C. Identify the location of the temporary nursery to hold the tree until it will be planted. D. Determine transporting route and ensure there is adequate clearance for safe passage past utility lines, overpasses, vegetation, and other possible obstructions. E. Determine if digging should be done in two phases by boxing the sides, waiting 90 days, and then completing the boxing. Section Effective: March i,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 11 TREE REMOVAL AND TRANSPLANTING F. Determine the size of box need for each tree to be transplanted. G. Clear adequate space for digging and moving the tree. Heavy equipment may include a backhoe, crane, and flatbed truck. H. Protect any trees that are to remain on the site from inadvertent damage by transplanting operations. Place fencing, barricades, weight dispersing materials, etc. as needed. I. Excavate the soil from around the tree, cut woody roots cleanly with a saw, and treat any cut roots requiring attention. Shave and shape the soil to conform to sides of the box. Place the box sides around the rootball and secure. Undercut the tree and insert boards to form a bottom. Place two beams at right angles to the bottom boards and two beams across to top. Attach beams together with rods or heavy metal bands. Fill in any gaps between rootball and the box with soil from the removal site. J. Lift the tree out of the ground with a crane or other device and place it on a flatbed truck. K. Tie down and tarp the tree crown to protect it from excessive moisture loss. L. Carefully transport the tree to the temporary nursery or planting site. M. Provide irrigation as needed. N. Protect the surrounding soil from compaction by placing plywood or 6 inches of wood chip mulch beneath the wheels of the equipment. O. Prepare the planting site by digging a plant pit twice as wide as the rootball and 6 inches deeper than the height of the rootball to allow for any settling. Rough up the sides of the hole with a shovel to disrupt any glazing. P. Place the tree in the new plant pit. Ensure the trunk is straight and plumb. Q. Remove the sides and bottom of the box. Backfill with site soil, tamping the soil to eliminate all air pockets. R. Do not place site soil over the top of the rootball. S. Do not apply vitamin B i or other"transplant shock" products. T. Stake or guy the tree. Build a 6-inch berm to enclose the rootball. Section Effective: March 1,2004 CONTRA COSTA COUNTY LANDSCAPE STANDARDS Page 12 TREE REMOVAL AND TRANSPLANTING U.

Refer to 3.06, Maintenance of Transplanted Trees. 3.06 Maintenance of Transplanted Trees A. The condition of transplanted trees must be closely monitored for two years following transplant. B. Until roots develop into the surrounding soil, the tree is dependent on water contained in the rootball itself. Therefore, plants shall be irrigated before the rootball becomes dry, but not so frequently that it remains wet. A sail probe shall be used to check soil moisture and water shall be applied as needed. C. Trees shall be pruned following transplanting to remove any broken or damaged branches. Any torn bark or wood shall be cut off with a knife. Do not shape the wound or apply wound paint.
