TREE MANAGEMENT PLAN TREE MANAGEMENT PLAN for LAWRENCE GROVES within the City of Boynton Beach, Fl. Prepared for GNM Associates, Inc. By The Land Stewardship Co. June 23, 1987 LAND STEWARDSHIP COMPANY 1495 Forest Hill Boulevard, West Palm Beach, Florida 33405 . (305) 433-4000 TREE PRESERVATION FORMAT WITH METHODOLOGY Tree Management Plan for Lawrence Groves Lawrence Road, Boynton Beach, Fl. page 1 This proposed development site is a producing citrus grove currently in acceptable health. All trees found on-site are citrus trees. It should be noted that citrus groves usually require a constant, labor intensive maintenance program which only an actively producing grove can afford and effectively undertake. The result of minimal maintenance (or no maintenance as can be reasonably anticipated for private residential lots) can be inducive to any number of health problems affecting the citrus community (adjacent and nearby groves) as well as society. Because of this situation coupled with existing marketing condi- tions and preferred image, the Developer reserves discretion in tree preservation, tree transplanting, and/or tree removal. I. Selective Clearing of Collector Roads A. A survey establishing the centerline of all platted collector roadways shall be prepared prior to commence- ment of any land clearing operations. B. Clearing operations shall commence only within the proposed pavement_ width plus thirteen feet (13') on both sides when a median island is fiQt present. c. Where a median island does occur, clearing operations shall commence only within the proposed pavement width plus four feet (4') on the median side plus thirteen feet (13') on the exterior side. D. The trees remaining undisturbed within the right-of-way shall be inspected by the City Forester and the Land- scape Architect jointly to determine which trees are alive and healthy and which trees are dead or diseased. Such dead or infected trees shall be flagged with ribbon and may be removed and destroyed. E. Upon completion of clearing activity, all area within the right-of-way will be examined for proposed utility entrenching activity and grade changes of plus/minus two inches (2.00") or more. The trees deemed healthy and not subject to such impact will be further identified as: LAND STEWARDSHIP COMPANY 1495 Forest Hill Boulevard, West Palm Beach, Florida 33405 . (305) 433-4000 Tree Management Plan Lawrence Groves page 2 1. Preserve (preserve in situ). The trees deemed healthy but subject to either utility and/or grade change activity will, at the discretion of the Developer, be further identified as: 2. Transplant (elsewhere on-site); 3. Adopt (by any public or private entity); 4. Remove and destroy. Construction of tree wells, either positive or negative in height, will not be considered due to stress to the tree and cost. II. Selective Clearing of Secondary and Minor Roads A. A survey establishing the centerline of all platted secondary and minor roadways shall be prepared prior to commencement of any land clearing operations. B. Clearing operations shall commence only within the easement for a cleared width of not greater than thirty-four feet (34') and shall follow the centerline. III. Preservation of Open Areas A. A survey establishing the boundaries and corners of all open areas shall be prepared prior to commencement of any land development operations. B. All trees existing within the open space areas shall be inspected by the City Forester and the Landscape Archi- tect jointly to determine which trees are alive and healthy and which trees are dead or diseased. Such dead or infected trees shall be flagged with ribbon and may be removed and destroyed. C. All live and healthy trees existing within the open areas shall, at the discretion of the Developer in view of proposed amenity uses therein, be preserved, trans- planted, adopted, or removed. LAND STEWARDSHiP COMPANY 1495 Forest Hill Boulevard, West Palm Beach, Florida 33405 . (305) 433-4000 Tree Management Plan Lawrence Groves page 3 IV. On-Site Trees to be Preserved in Place A. All trees, including trees within residential lot boundaries, not affected by construction activities, will be preserved in place and will be cleared of dead branches and wood. B. Fertilizer in the amount of two ounces per inch of diameter of tree, measured at four feet above grade will be drilled into the soil at a point of circumference equal to the dripline of the tree. The fertilizer will be a slow release or sulphur coated substance with a guaranteed analysis of 6-6-6. c. A barricade, four feet in height, will be constructed at the drip line of the tree. This barricade will con- sist of wood and/or wire fabric and will be constructed to repel the pressures of construction stress to trunk and roots. D. Trees are to be supplemented with additional water in event of drought during construction. Supplemental watering should amount to eighty gallons of potable water per week and be placed by hand inside the drip line. v. Trees Designated to be Transplanted On-Site A. All trees to be transplanted on-site must first be limbed up to six feet (6') of clear trunk. Dead wood and limbs must be pruned from the crown. The crown of the tree must then be reduced by one-third in a manner of uniformity and to represent a crown form indicative of the species. All trimmings are to be removed from the vicinity. B. Root pruning of 240 degrees of the circumference of roots measured a minimum of forty-eight inches (48") from the base of the tree trunk. The root prune ditch will measure at least twelve inches (12") wide and twenty-four inches (24") deep. The ditch will be made with a sharp spade or saw and any root encountered will be cleanly and evenly cut. The pruning ditch will then be backfilled with one-half soil and one-half woodchips. The ditch will then be tamped and thoroughly watered. The balance of the soil will then be dammed around the tree to form a basin for retaining water within the root pruned area.

Maintenance watering of fifty gallons of clean water, applied by hand two times per week, will be applied to the basin. The time of on-going maintenance will be for six (6) consecutive weeks. At six weeks, the root edge will be checked to measure the evidence of newly formed root growth. If an inadequate amount of root growth (to be determined by the City Forester) is found, the maintenance program will continue for another two weeks. D. Transplanting activities with a "Tree Spade" or tree crane will then commence. All transplanting and bracing will be done in accordance with details and diagrams shown on Landscape Plans. Upon transplant, a maintenance period, as described in the General Notes, will be conducted for sixty (60) days. VI. On-Site Trees to be Adopted or Removed A. The City Forester will be contacted to determine if public or private entities are interested in surplus trees from this site. A limitation of time, commen- surate with on-site transplants, will be enforced in order to avoid construction delays. B. Trees that are not claimed and/or removed by interested entities prior to construction within that respective vicinity will be removed by the Developer and destroyed. VII. Common Area Tree Maintenance Program A. During the development process the Developer will main- tain living citrus trees according to the guidelines established above. Upon completion of any phase of the development, the Developer may, at his discretion, assign responsibility of maintaining living citrus trees, as well as all other trees, to an association of homeowners if and when such an association exists. When a homeowners association is given responsibility to maintain all trees within the common areas then that same association shall maintain the trees in accordance with the maintenance plan outlined below. B. It is not reasonable to expect the citrus trees in the common area will be maintained as stringently as citrus trees are in a producing grove. However, some form of LAND STEWARDSHIP COMPANY 1495 Forest Hill Boulevard, West Palm Beach, Florida 33405 . (305) 433-4000 Tree Management Plan Lawrence Groves page 5 maintenance must be continued for the sake of the adjacent and nearby commercial citrus groves. The goal, therefore, is to preserve the general impression and image of a citrus grove, yet, it is not to be expected that the citrus trees will be maintained as normally is the custom. The following maintenance plan is minimal in scope, application, and execution. 1. Irrigation; 2. Fertilization; 3. Spraying; 4. Pruning. c. Irrigation: All trees and particularly the citrus trees shall be irrigated as needed in an appropriate manner. (See IV.-D. above.) D. Fertilization: The citrus trees in particular shall be fertilized four times per year using a prepared fertili- zer with a guaranteed analysis of 6-6-6. This substance shall be applied to the citrus trees in a manner normal- ly implemented within a producing citrus grove. E. Spraying: The citrus trees shall be sprayed a minimum of four (4) times per year and two (2) additional applica- tions may be required during any year. 1. March: use Benelate for citrus scab. 2. June: use Ethion plus citrus oil for rust mite and general appearance. 3. September: use Chlorabenzalate for rust mite. 4. November: use copper or Benelate for citrus greasy spot. The two additional applications could be any of the mentioned chemicals reapplied in the event the initial application failed. Application should be conducted by experienced personnel licensed for such operations. F. Pruning: The preservation of image shall be conducted on a cosmetic approach. Consequently, selective pruning shall be the rule. END LAND STEWARDSHIP COMPANY 1495 Forest Hill Boulevard, West Palm Beach, Florida 33405 . (305) 433-4000
