9.2 Mulching

When mulching is called for, approximately two (2) inches, loose thickness, of the mulch material shall then be applied uniformly over the seeded area, and the mulch material cut into the soil with the specified equipment, so as to produce a loose-mulched thickness of three (3) to four (4) inches. Care shall be exercised that the materials are not cut too deeply into the soil. When green mulch is used the green mulch shall be incorporated into the soil not later than two (2) days after being cut and no artificial watering of mulch shall be done before it is applied.

The mulch material used shall normally be dry mulch. Dry mulch shall be straw or hay, consisting of oats, rye, or wheat straw, or of pangola, peanut, coastal Bermuda or Bahia grass hay; and shall be free of noxious weeds and undesirable grasses and plants. Any plant officially listed as being noxious or undesirable by any Federal Agency and Agency of the State of Florida or a local jurisdiction in which the project is being constructed shall not be used. Only undeteriorated mulch, which can be readily cut into the soil, shall be used. Green mulch shall consist of live coastal Bermuda, or other approved type of grass, and shall be free from weeds and obnoxious or undesirable grasses. No green mulch which, in the County’s representative’s or designee’s opinion, has been allowed to become sufficiently dry as to lose its growth-producing benefits will be allowed to be used. In the event that the subsequent stand of grass is found to be contaminated with weeds or other obnoxious or undesirable growth, and it can be determined that such growth was introduced with the green mulch, the Contractor shall be required to effectively eliminate such undesirable growth, at his own expense. When specified or permitted by the County’s Representative, manufactured mulches may be allowed. Such mulches may consist of jute, cotton, or other fiber materials, plastic sheeting, netting, chemical adhesive soil stabilizers, or their approved coverings

9.3 Source Requirement for Seed and Mulch

The Contractor shall comply with all current restrictions regarding the movement of seed and mulch material, into or within areas which are outside of quarantine boundaries for the white fringed beetle, witchweed, and West Indian sugar cane borer weevil, as issued by the Division of Plant Industry, Florida Department of Agriculture and the Animal and Plant Health Inspection Services, U.S. Department of Agriculture.

9.4 Rolling Immediately after completion of seeding, the entire grassed or mulched area shall be rolled thoroughly with the equipment specified in Section 1.2. At least two trips over the entire area will be required.

9.5 Watering

Newly seeded areas are not to be watered to force the seed germination but only to sustain grass growth.

9.6 Operations on Steep Slopes

On steep slopes, where the use of a machine for the cutting-in process described in Section 2.2 is not practicable, the construction operations shall be modified as follows:

The fertilizer shall be applied uniformly, at the rate specified, and shall be raked in and thoroughly mixed with the soil to a depth of approximately two (2) inches. The seeding operations shall follow the fertilization.

When mulching is called for, the mulch material, in lieu of being cut into the soil, may be anchored down. Anchoring shall be done by either of the following methods:

9.6.1 Placing a layer of soil, approximately two (2) inches thick by nine (9) inches wide at the limits of the mulch, and spotting soil piles over the rest of the area at a maximum spacing of four (4) feet.

9.6.2 Spreading a string net over the mulch, using stakes driven flush with the top of the mulch, at six (6) foot centers, and stringing parallel and perpendicular, with diagonals on both directions.

9.7 Materials

The materials used in this work (seed, mulch, fertilizer and water shall conform to the requirements as indicated in Section 10.

9.8 Equipment

Equipment includes a fertilizer spreader, seed spreader, equipment for cutting mulch into soil and rollers. The fertilizer spreader, the device for spreading fertilizer, shall be capable of uniformly distributing the material at the specified rate. The seed spreader shall be an approved mechanical hand spreader or other approved type of spreader. The mulching equipment shall be of a type capable of cutting the specified materials uniformly into the soil and at the required depth. Harrows will not be allowed. A cultipacker, traffic roller, or other suitable equipment will be required for rolling the grass areas.

9.9 Construction Methods

Fertilizing, seeding and mulching will not be permitted when wind velocities exceed fifteen (15) miles per hour. Seed shall be sown only when the soil is moist and in proper condition to induce growth. No seeding shall be done when the ground is frozen, unduly wet or otherwise not in a tillable condition.

9.10 General

Whenever a suitable length of roadway, slopes, or adjacent areas has been graded and is ready for seeding and a delivery order has been issued requiring seeding, the Contractor shall proceed at once with the grassing of available areas. Prior to the issuing of said delivery order, work must be coordinated with the Contractor.

9.11 Sequence of Operations

The operations involved in this work shall proceed in the following sequence: ground preparation, fertilizing, seed spreading and cutting in mulch with follow-up maintenance and watering as required.

9.12 Ground Preparation: See ground preparation under SODDING section

The square feet unit price for seeding and mulching shall be inclusive of labor, materials, erosion control, grading, compaction, watering and any other incidentals needed to complete the work.

10. HYDRO SEEDING (without Bonded Fiber Matrix (BFM))

Hydro seeding: The Contractor shall use equipment specifically designed for mixing the wood fiber, seed, fertilizer, tackifier and dye, and applying the slurry uniformly over the areas to be hydro seeded. Wood fiber shall be used that is made of one hundred percent (100%) hardwood or softwood and does not contain reprocessed wood or paper fibers. The Contractor shall ensure that a minimum of fifty percent (50%) of the fibers are equal to or greater than fifteen hundredths (0.15) inch in length and a minimum of fifty percent (50%) of the fibers will be retained on a twenty-five-mesh screen. Mix fertilizer shall be used as required into the hydro seeding slurry, Mixing seed into the slurry at rates in accordance with Design Standards, Index 104 of FDOT’s Standard Specifications for Road & Bridge Construction. The Contractor shall ensure that the dye does not contain growth or germination inhibiting chemicals. When polyacrylamide is used as part of hydro seeding mix, only anionic polymer formulation with free acrylamide monomer residual content of less than five (5%) shall be used. Cationic polyacrylamide shall not be used in any concentration. The spraying of polyacrylamide containing mixtures onto pavement is absolutely prohibited as they may include tackifiers, flocculants or moisture-holding compounds.

The contract price per square feet for hydro seeding (without bonded fiber matrix) shall be full compensation for all work required in the preparing of ground, furnishing and placing the hydro seeding, watering and maintaining the hydro seeded areas to ensure a thick, healthy established stand of grass and root system for thirty (30) calendar days after the final inspection. However, if the hydro seeding has not produced a healthy established stand of grass and root system, the hydro seeding shall be reapplied at no additional cost to the County, following all sequence of operations as outlined within the contract.
