SECTION 01 56 40 – TREE PROTECTION AND TREE SAFETY STANDARDS

PART 1 – GENERAL

Trees are critical green infrastructure with qualitative and quantitative benefits. The preservation and protection of existing trees in and around construction sites is imperative during the planning, execution, and post-construction phases of development. Contractor is required to work with and notify Tree Warden of any planned or unforeseen tree impacts.

SAFETY STANDARDS

A. All equipment to be used and all work to be performed must be in full compliance with the most current revision of American National Standards Institute Z133 Safety Requirements for Arboricultural Operations. These standards are made part of this contract by this reference.

B. Personal Protective Equipment (PPE) is required by all in all circumstances.

C. The Contractor shall be solely responsible for pedestrian and vehicular safety and control within the work site and shall provide the necessary warning devices, barricades, and ground personnel needed to give safety, protection, and warning to persons and vehicular traffic within the area.

D. Blocking of public streets shall not be permitted unless prior arrangements have been made with the City of New Haven and is coordinated with appropriate departments. Traffic control and any additional costs incurred on the contractor’s behalf is the responsibility of the Contractor unless arrangements are made with the Tree System Coordinator/Tree Warden.

LIABILITY FOR DAMAGE TO PROPERTY AND/OR PLANT MATERIAL

Any tree damage caused by the Contractor should be repaired immediately at no additional expense and to the satisfaction of the City of New Haven. Trees damaged beyond repair, as judged by a qualified arborist acceptable to the City of New Haven and the Contractor, whose expenses shall be jointly covered by both parties, are to be removed at no expense to the City, and replaced according to the Tree Fund Policy. The Tree Fund exists to incentivize the preservation of existing street trees and to provide compensation for lost ecosystem benefits when the impacts on a street tree are significant enough to warrant removal or when a tree is illegally removed or damaged. The money paid into the Tree Fund is used to support urban forest management city-wide. Payments into the tree fund are calculated at a rate of $250/inch of DBH, diameter at breast height (4.5’), for each tree removed. The payment can be adjusted on a 1:1 basis for caliper inches of new trees replanted.

Replacement tree plantings must be warrantied for 3 years from the date of planting and the contractor is responsible for watering the new trees at a rate of 25 gallons/week from April through October. Contractor will be responsible for all costs associated with removing the trees and replanting. Including, but not limited to, the removal of trees, stumps, hauling of all debris, traffic control, and replanting costs. Damage to other plant material, such as shrubs and perennials, is calculated at the reproduction replacement value and subject to the same establishment protocol.

Funds invoiced for damage to trees and plants will be deducted from moneys owed the contractor.

UNCLASSIFIED EXCAVATION

20.01.01 DESCRIPTION

Unclassified excavation shall consist of the removal and satisfactory disposal, in the manner herein required, of all material other than water taken from within the limits of the work contracted for, the removal of which is necessary for the construction of the embankment, subgrade, shoulders, slopes, entrances, gutters and other miscellaneous construction, to the dimensions and limits shown on the plans or as ordered by the Engineer. It shall also include the disposal of surplus or unsuitable material.

20.08.2 MATERIALS

NOT APPLICABLE

20.08.3 CONSTRUCTION METHODS

Unclassified excavation shall be made in conformity with the requirements of the plans. The slopes of earth cuts shall be smooth, neat and true to the lines given or as directed.

Stumps, trees, sod, weeds and material that will not compact under rolling shall not be placed in embankments, but shall be disposed of as directed by the Engineer.

Placement of Excavated Material: Except as specifically provided elsewhere herein, suitable material removed from the excavation shall be used as directed in the formation of embankments, subgrade, shoulders, etc., and at such other places as may be required.

When embankments are to be constructed on existing slopes steeper than 1 vertical to 3 horizontal, the slope of the existing ground on which the embankment is to be placed shall be plowed deeply or cut into steps before the filling is begun.

Embankments are to be constructed of earth, rock or a mixture of earth and rocks, deposited in successive layers for the full width of the embankment. Except, as herein after permitted, the depth of each layer shall not be more than 12 inches before compaction. Each layer shall be leveled off by the use of blade graders or bulldozers with adequate power for the work involved. The entire area of each layer shall be compacted by distributing the hauling over the area, by the use of tread type equipment, by power rollers weighing not less than 10 tons, or by other mechanical means satisfactory to the Engineer.

Compactions shall be continued until each layer is thoroughly consolidated for its full width. The dry density of each layer after compaction shall not be less than 90 percent of the dry density achieved by the A.A.S.H.O. Method T-99 for that soil. Depending on the material and weather conditions, it may be necessary to supplement mechanical compaction methods by control of moisture in the material.

No stone over 5 inches in its greatest dimensions shall be placed within 12 inches of the subgrade. The subgrade shall be the bottom of the pavement base course.

Surplus Excavated Material: All surplus excavated material shall be used as required to uniformly widen embankments, to flatten slopes, to fill low places in the right-of-way, or for such other purposes as the Engineer may direct. Any surplus or unsuitable material not required, or permitted to be used for such purposes shall be removed from the limits of the work and deposited at such point or points as the Engineer may direct on other property owned by the City of New Haven or disposed of in a manner approved by the Engineer. Material shall be deposited and spread uniformly as directed by the Engineer, within the limits of the area designated by him to receive the surplus material.

20.08.4 METHOD OF MEASUREMENT

Payment lines for "Unclassified Excavation" shall coincide with the slope and subgrade lines as shown on the plans or as ordered.

The amount of unclassified excavation will be determined by the method of average end areas.

20.08.5 BASIS OF PAYMENT

Botanical Name Common Name %Purity %Germination %by weight

Festuca ruba Creeping Red or

Chewing's Fescue 98 90 50

Poa pratensis Kentucky Bluegrass 85 75 25

Poa pratensis merion merion Kentucky Bluegrass 85 75 25

Seed shall be delivered pre-mixed to the Site in standard size sealed containers bearing the vendor's guaranteed statement attesting to the composition of the mixture and to the percentages of purity and germination of each variety. Seed shall be stored in such manner that its effectiveness is not impaired.

Samples of seed shall be taken as directed by the Engineer, and shall be submitted to the State Agricultural Station for analysis.

Sod: All sod shall be well-established, good quality, permanent lawn grass, grown on open ground in an approved area. It shall be strongly rooted, containing seventy-five (75) percent Merion Bluegrass (Poa pratensis merion) and twenty-five (25) percent Pennlawn Fescue, free of pernicious weeds and coarse, burned or bare spots.

The sod shall be in rectangular sections varying in length between 3 feet and 6 feet and shall be of uniform width not to exceed 18 inches. Sod shall have a uniform soil thickness of one and one-half (1-1/2) inches.

Grass shall have been mowed to a height of two (2) inches before lifting. Sections shall be of such size as to be lifted without breaking, tearing, or loss of soil.

The Contractor shall furnish the Engineer with an adequate sample for inspection and approval before any sod is delivered to the site.

Loam: The Contractor shall furnish soil samples to the Engineer as requested at no additional cost to the City. Generally, the Engineer shall submit a sample of loam material proposed to be used on the project to a U.S. State or Agricultural Station for analysis and corrective recommendations if necessary. The Engineer shall advise the Contractor as to the corrective recommendations required to make the loam acceptable for use on the project.

Loam material furnished from sources outside of the project limits shall consist of loose, friable, sandy loam or loam topsoil free of admixture of subsoil, refuse stumps, roots, rock, brush, weeds, and other material which will prevent the formulation of a suitable sod or seed bed. Loam shall be that portion of the soil profile defined technically as the "A" horizon by the Soil Science Society of America. It shall contain not less than 6 percent nor more than 20 percent organic matter as determined by loss-on-ignition of oven dried samples drawn by the Engineer. Loam shall be free of stone 1-1/4 inches and larger in over-all dimensions. The Contractor shall notify the Engineer of the location from which he proposes to furnish loam at least 15 calendar days prior to delivery of loam to the project site from that location.

The loam and its source shall be inspected and approved by the Engineer prior to delivery to the project site. Any loam delivered to the project which does not meet the above requirements will be rejected and shall be immediately removed from the project site and replaced by the Contractor with acceptable material at no additional cost to the City.

When loam is not furnished from outside sources, the material used shall be the loam stripped during the course of excavation on the project site. All roots, stumps, debris, pavement, brush sods and other objectionable materials shall be removed by the Contractor prior to its use.

Chlordane: Chlordane shall be a commercial product in dry powder form, of recent manufacture, delivered to the Site in original unopened containers bearing the manufacturer's guaranteed statement of analysis giving the percent of active ingredient.
