TREE PROTECTION

PART 1 GENERAL

1.01 RELATED DOCUMENTS: The General Contract Conditions, Drawings, and Division - 1

Specification sections apply to Work of this section.

1.02 SUMMARY: The work of this section consists of retention and protection of trees during the construction of the project.

1.03 GENERAL REQUIREMENTS:

A. There should be daily supervision of field crews by the City Forestry Staff or Project Consulting Arborist during the critical phases of the project: for example, demolition of existing concrete; root pruning; construction of retaining walls and construction of new curb or sidewalk in tree protection areas. Cheyenne Botanic Garden Staff may require a consulting arborist be hired to oversee the project.

B. If it appears that the completion of the construction may cause damage to the branches of any tree, the Contractor shall contact the Cheyenne Botanic Garden Staff. The Cheyenne Botanic Garden Staff will make a determination as to whether such damage is eminent.

C. To prevent or minimize soil compaction, designated routes for equipment and foot traffic by work crews shall be determined prior to commencing construction activities, and shall be indicated in the tree protection plan to be submitted by Contractor. These routes shall be marked at the site, prior to commencement of construction, with tree protection fencing and signage as specified in Paragraphs 3.6 and 3.7 of this section. A Tree Protection Plan shall be submitted and approved.

D. Motorized equipment and trailers, including tractors, bobcats, bulldozers, trackhoes, trucks, cars, and carts shall not be allowed access within tree protection areas. Should access be necessary within designated tree protection areas, the existing grade shall be covered with six (6) to eight (8) inches of wood mulch to help distribute the weight of equipment and to minimize soil compaction and rutting. Plywood and/or mulch is not acceptable bridging material for driving over exposed tree roots. Exposed tree roots shall not be driven over. Cheyenne Botanic Garden Staff or Project Consulting Arborist shall be notified and shall approve of the access and driving surface prior to its use.

E. Materials and supplies shall not be stockpiled or stored within the tree protection area.

Should temporary storage be necessary within designated tree protection areas, the existing grade shall be covered with double, overlapping sheets of ¾ inch thick plywood, or six (6) to eight (8) inches of wood mulch to help distribute the weight of materials or supplies and to minimize soil compaction.

F. Under no circumstances shall any objects or materials be leaned against or supported by a tree's trunk, branches, or exposed roots. The attachment or installation to trees of any sign, cable, wire, nail, swing, or any other material that is not needed to help support the natural structure of the tree is prohibited. Standard arboricultural techniques such as bracing or cabling that are performed by professional arborists are acceptable upon approval by the Cheyenne Botanic Garden Staff or Project Consulting Arborist.

G. Appropriate tree pruning and/or removal permits must be secured prior to beginning work.

1.04 DEFINITIONS:

A. TREE PROTECTION AREA: Generally, a tree protection area should consist of the ground encompassing from 1.5 (minimum) to 2.0 times the distance between the trunk and dripline, or one linear foot away from the trunk base for every inch diameter of the trunk, whichever is greater. (See section below). Areas of ground covered by pavement, buildings, or other permanent structures where the presence of roots is minimal or negligible, are excluded. The area under or within the tree's dripline is also referred to as the "Critical Root Zone" (see below).

1. With groups of trees or where an array effect is present, there may be discontinuous (non-overlapping) perimeters of tree protection areas, which result in difficult to maintain or ineffective tree protection fencing. In these cases, even though tree protection areas do not overlap, they should be treated as though they do if the distance between the perimeters of such areas is less than thirty

(30) feet. In effect, this will artificially enlarge the area of tree protection, but will result in a more clearly defined, manageable area.

B. DRIPLINE: The outermost edge of the tree's canopy or branch spread. The area within a tree's dripline is all the ground under the total branch spread.

C. CRITICAL ROOT ZONE: Generally, all of the ground area included in the dripline.

D. DIAMETER (CALIPER): The size (in inches) of a tree's trunk is measured at:

1. six (6) inches above grade for trunk diameters up to and including four (4) inches;

2. twelve (12) inches above grade for trunk diameters from four (4) inches up to and including eight (8) inches; and

3. four and a half (4½) feet above grade for trunk diameters greater than eight (8) inches; in accordance with guidelines established in the "Guide for Plant Appraisal". All measurements should be rounded to the nearest inch.

E. HIGH-VALUE SHRUB: Any specimen shrub with an appraised value of $100.00 or more.

F. PROJECT CONSULTING ARBORIST: An independent consultant with a degree in a field related to arboriculture, and at least five years field experience in tree preservation or on-site monitoring of public works or construction projects involving tree retention and protection. The Consultant should be an active member in the American Society of Consulting Arborists and International Society of Arboriculture.

1.05 REFERENCE STANDARDS AND GUIDELINES:

A. Contractor shall comply with applicable requirements and recommendations of the most current versions of the following standards and guidelines. Where these conflict with other specified requirements, the more restrictive requirements shall govern.

PART 3 EXECUTION

3.01 CONSTRUCTION REQUIREMENTS: This section provides standards and guidelines for the retention and protection of trees and high-value shrubs for any proposed public works or construction project.

3.02 DEMOLITION OF EXISTING CONCRETE: Caution should be used during removal of existing street, curb, gutter, sidewalk, drain inlets, and other concrete and asphalt demolition, to minimize injury to tree root systems. The following procedures should be used when removing existing concrete.

A. Breaking of the existing concrete and asphalt for removal should be done in a manner that will minimize ground disturbance and vibration.

B. Curbs and sidewalks within designated tree protection areas and critical root zones shall be removed by hand. When removing existing sidewalks and curbs, care should be taken to avoid injury to roots located under, over, or adjacent to paved surfaces.

C. Roots and root-trunk flares growing over curbs should not be injured during breaking of curbs and removal of debris. Wood and bark tissues shall not be injured by striking tissues with equipment.

D. During the removal of concrete, all root systems and soil areas exposed shall not be disturbed.

E. Motorized equipment and trailers, including tractors, Bobcats, bulldozers, trackhoes, trucks, cars, and carts are to be limited to access on the existing paved street only.

Access is not allowed behind the curb within tree protection areas.

F. Should access be necessary within designated tree protection areas, the existing grade shall be covered with double, overlapping sheets of ¾ inch thick plywood, or six (6) to eight (8) inches of wood mulch to help distribute the weight of equipment and to minimize soil compaction and rutting. Plywood and/or mulch is not acceptable bridging material for driving over exposed tree roots. Exposed tree roots shall not be driven over. The Cheyenne Botanic Garden Staff or Project Consulting Arborist shall be notified and shall approve of the access and driving surface prior to its use.

3.03 CONSTRUCTION OF SIDEWALKS, CURBS, CONCRETE, ASPHALT PAVING AND

DRAINAGE INLETS: The following procedures shall be used when constructing sidewalks, curbs, concrete, asphalt paving, and drainage inlets.

A. Keep all materials and equipment within the street bounded by existing curbs.

B. Protect exposed roots from contamination by stabilization materials and concrete.

C. Locate concrete washout areas away from roots and tree protection areas.

D. When excavating for the construction of inlets, excavated soil shall be deposited in trucks and hauled off or deposited temporarily on ¾ inch thick plywood outside the critical root zone. Excavated and fill soil shall not be deposited, even temporarily, on unprotected natural grade.

E. After proper pruning, as needed, cover exposed roots within thirty (30) minutes to minimize desiccation. Roots may be covered with soil, mulch, or moistened burlap (7 ounce or equivalent), and shall be kept moist during the period until the final grade is established.

F. Where possible, sidewalks should be raised, narrowed, curbed, or relocated to prevent cutting and removing major roots (e.g. roots greater than three inches in diameter).

G. Place a sheet of six (6) mil or thicker plastic over the grade within affected portions of tree protection areas prior to pouring concrete sidewalks, curbs, inlets, ramps, and driveway approaches. The plastic will assist in providing a non-leaching barrier between the concrete, soil and roots.

H. Construct new sidewalks on, or above, the existing grade instead of excavating into root zones. The new grade shall not interfere with sheet-flow drainage.

I. Limit grading to a maximum of two (2) inches of fill over natural grade within critical root zones. Fill should consist of sandy loam topsoil. Clay soils shall not be used as fill.

When using fill soil, the existing surface to receive fill should be scarified prior to filling.

Any filling operation should not occur during water saturated soil conditions.

J. Existing soil may be used as a form for back of curb and gutter, with or without the use of a thin masonite-type form, although a masonite form is preferred. This will minimize excavation in the critical root zone and prevent undue injury to the roots. This method is unnecessary in areas outside the critical root zone. Place a layer of Typar BioBarrier between the curb and tree roots to help inhibit root growth that may exploit small cracks in the curb. Where appropriate, use curbs with discontinuous footings to maintain natural grade near the base of trees adjacent to the curbing, and to minimize injury to roots and root flares.

K. Provide for easy concrete removal and replacement where an obvious raised root may cause sidewalk cracking in the future. This can be accomplished by installing an expansion joint on either side of the root or by etching the concrete on either side of the root to allow that particular section to be broken out and replaced. Compaction rating for the replacement walkway should not exceed 80% Proctor density. Tree roots will continue to slowly add girth every year; therefore, the base material needs to be malleable (e.g. suitable subgrade aggregates, crushed granite, or compacted sand) to prevent a fulcrum or pressure point which can crack or heave the walkway.

L. Where appropriate, and under the direction of the Cheyenne Botanic Garden Staff or

Project Consulting Arborist, root restricting barriers can be installed with a minimal amount of disturbance. There are several promising landscape related materials used as barriers to root growth, especially away from sidewalks, curbs and streets. Three such materials are:

1. a stiff nylon woven fabric (Q899 nylon fabric with extra firm finish from Jason

Mills, Westwood, NJ);

2. 14-mesh or smaller copper wire screen; and

3. Typar BioBarrier (REEMAY, Inc., Old Hickory, TN). The nylon fabric has holes approximately 1/26th-inch square separated by strands approximately 1/26th-

CHEYENNE, WY

TREE PROTECTION

32 93 03 - 5 inch thick, with strands fused together. Copper screen has been shown to be effective in controlling seedling root growth. Typar BioBarrier is a commercial product developed specifically to control roots of trees, and consists of a felt-like spun-bounded polypropylene fabric to which polyethylene pellets are attached at one and a half (1½) by one and a half (1½) inch spacing. The pellets are impregnated with the herbicide Trifluralin and release it slowly over time (many years). After a two (2) foot deep, narrow trench is dug adjacent to the curb, sidewalk, or other structure involved, and after any affected roots are properly pruned, the material of choice should be placed against the side of the wall closest to the roots that were severed (side of the wall farthest from the structure being protected). Note: This procedure should not be used if large, existing roots (four (4) inches or larger in diameter) will be severed. The nylon fabric and copper screen will constrict roots to the size of the openings in the material;

beyond the constrictions, roots will be greatly stunted except for knobs that form against the barriers. The barrier should be installed at least eighteen (18) to twenty-four (24) inches deep (in a vertical plane).

M. In areas where roots have to be removed for construction of drain inlets, roots shall be severed prior to excavation to eliminate unnecessary tearing of roots by equipment.

1. Excavate soil by hand at the construction cut limit to a depth of thirty (30) inches or to the depth of the required root cut, whichever is less.

2. Prune roots as specified in Paragraph 3.5 of this section.

3. Protect exposed roots as specified in Subparagraph 3.3E of this section.

N. Concrete or chemicals spilled within tree protection areas should be completely removed.

Contamination soil shall be completely removed at the time of the spill and removed by hand without disturbance to root systems. Appropriate soil should be added as necessary to restore the grade.

3.04 IRRIGATION OR UTILITY INSTALLATION:

A. PROTECTION OF TREES AND HIGH-VALUE SHRUBS: Contractor shall protect all trees and high-value shrubs from injury due to irrigation related work. All injuries to trees and high-value shrubs shall be mitigated to the satisfaction of the Owner, and, if appropriate in accordance with guidelines established in the "Guide for Plant Appraisal".

All costs of such mitigating shall be charged to and paid by the Contractor. See Paragraph 3.9 of this section for definition of high value.

1. All irrigation lines shall be indicated on construction plans and pre-approved by the Cheyenne Botanic Garden Staff or Project Consulting Arborist.
