No stock piling of material on the roadway, within tree protection zones (TPZ), or on the sidewalk is allowed.

All extra dirt and/or debris must be removed daily as part of the daily clean-up process. The roadway and the sidewalks must be swept daily. All costs associated with daily clean-up process and sweeping must be included in the Lump Sum bid for Clearing and Grubbing. All buildings, structures, utilities, and other obstructions indicated on the plans to remain, must be carefully protected against displacement or damage.

Where possible, all trenching or excavation within tree protection zones (TPZ) shall be done by hand or an air spade. After excavation, all tree roots greater than one inch (1”) in diameter must be cleanly pruned or saw cut, not crushed or torn. Where it is not possible to hand trench, mechanical excavation may be approved by the Engineer.

Cutting tree roots greater than 3” in diameter in the critical root zone (CRZ) or tree roots greater than six inches (6”) in diameter within the TPZ shall be reviewed by a County Arborist to determine if a tree designated to remain may need to be removed to prevent future liability.

The Contractor must make his own inspection to determine the character, density and extent of trees, vegetation, and other items subject to removal and disposal under these provisions. The attention of the Contractor is directed to the fact that the burning of debris resulting from clearing and grubbing operations will not be permitted within County-owned lands or rights-of-way. Nothing in these provisions must be construed to authorize the removal or disturbance of any tree or other form of vegetation, or any marine, land or air creatures’ natural habitat, which may be subject to the jurisdiction of regulatory agencies. This Section must also include the cost for trimming of trees and disposal of the trimmings, as shown on the plans and/or required for construction of project.

Description: The work consists of furnishing all labor and materials required to install the TRM with proper anchoring and toe-ins to existing ground as shown in the plans. The contractor shall install the TRM per the details in the plans.

Turf reinforcement mat (TRM) shall be a machine-produced mat of 100% UV-stabilized, high denier polypropylene monofilament yarns woven into permanent, high-strength, three-dimensional turf reinforcement matting. Available in either a green/black or a tan/black coloring, the mat shall be composed of polypropylene yarns woven into a uniform configuration of resilient, pyramid-like projections. The mat provides sufficient thickness, optimum open area, and three dimensionalities for effective erosion control and vegetation reinforcement against high flow induced shear forces. The mat has high tensile strength for excellent damage resistance and for increasing the bearing capacity of vegetated soils subject to heavy loads from maintenance equipment and other vehicular traffic. The material has very high interlock and reinforcement capacities with both soil and root systems and is designed for erosion control applications on steep slopes and vegetated waterways.

Materials

Properties

Performance Full-Scale laboratory testing performed by an independent 3rd party testing facility with associated engineered calculations certifying the hydraulic capacity of the proposed Tied-Concrete Block Erosion Control Mat meets the following requirements:

Equipment Provide the proper equipment to place the mat that will not damage the mat material or disturb the top soil subgrade and seed bed.

Construction Prior to installing TRM, prepare the subgrade in accordance with manufacturer specifications. All subgrade surfaces to be smooth and free of all rocks, stones, sticks, roots, and other protrusions or debris of any kind.

PAY ITEM NO. 571-1-13 CONCRETE MATTING

Description: This work shall consist of furnishing all labor, materials, equipment, loading, transporting and installation of the concrete matting in accordance with this specification.

Concrete matting is manufactured from individual concrete blocks tied together with high strength polypropylene biaxial geogrid. Each block is tapered, beveled and interlocked and includes connections that prevent lateral displacement of the blocks within the mats when they are lifted for placement.

Tied Concrete Block Mats shall be Flexamat, manufactured by Motz Enterprises, Inc. or approved equal (See Alternative Products).

Blocks. Furnish blocks manufactured with concrete conforming to the cement requirements of ASTM C150 and to the aggregate requirements of ASTM C33. Meet a minimum compressive strength of 5,000 psi at 28 days. Furnish blocks that have a minimum weight of 3 lb. per block and placed no further than 2 in. apart.

Polypropylene Bi-Axial Geogrid. The geogrid will be composed of Polypropylene multifilament yarns coated with an acrylic based coating which is designed to resist degradation in environments with exposure to water and low pH (,4 pH) and high pH (>9 pH). When combined with the revetment mat this will yield a high tenacity, low elongating, and continuous filament polypropylene fibers that is securely cast into and embedded within the base of the concrete blocks and obtains connection strength greater than that of the geogrid. Ensure the geogrid meets the requirements of Table 1:

Underlayment Materials. Includes 5-Pick Leno Weave Fabric, Curlex® II and Recyclex TRM-V, or approved equivalent. The backing material shall be packaged within the roll of the concrete matting.

Leno Weave Five-Pick Netting: This is a woven, white polypropylene netting that provide added strength and support to the underlayments.

Curlex® II erosion control blanket (ECB) consists of a specific cut of…
