c. Perform sprigging a maximum of 24 hours after initial harvesting

PART 2 PRODUCTS

2.1 HYDROSEED

Seed mix must be native and tolerant of existing conditions. Protect seed from heating, drying, and contamination during transport, storage and handling on-site. Store seed in a cool, dry location.

a. All seed must be of western Washington or western Oregon genetic source. Submit proposed seed source(s) prior to the start of construction for approval by the CO. Commercially-grown seed used on this project must be in conformance with the Washington State Seed regulations (15.49 RCW, WAC 16-301). Provide State-certified endophyte-enhanced seed of the latest season's crop delivered in original sealed packages, bearing producer's guaranteed, analysis for percentages of mixtures, purity, germination, weed seed content, and inert material. Wet, moldy, or otherwise damaged seed will be rejected.

b. For collected seed, or other non-commercially grown seed, provide the name of the seed collector, location of collection, and the dates of collection. Field mixes will be acceptable when field mix is performed on site in the presence of the CO.

2.2 WATER

Submit proposed water source for approval by the CO, and be of suitable quality for irrigation. Use collected stormwater or graywater when available.

2.3 BONDED FIBER MATRIX (BFM)

BFM will be "SoilGuard", "EcoAegis", "HydroBlanket", or approved equivalent and contain all ingredients including tackifier, crosslinkers and other proprietary ingredients.

2.4 TACKIFIER

Use Stockpam, SoilBinder or approved equivalent as tackifier for hydroseeding. For the PAM use a long chain, water-soluble or linear, SECTION 32 90 00.00 25 Page 6 non-crosslinked, anionic (>20 percent hydrolysis) or nonionic. PAM tackifier will be certified for compliance with ANSI/NSF Standard 60 for drinking water treatment and have a 0.05 percent maximum and an average

0.02 percent AMD concentration. The PAM anionic charge density may vary from 2-30 percent; a value of 18 percent is typical.

2.5 DUNE GRASS SPRIGS

Sprigs must be healthy living stems, stolons, or rhizomes and attached roots of locally adapted grass without adhering soil, including two to three nodes and from 4 to 6 inches long. Obtain sprigs from a local source.

Provide sprigs which have been grown under climatic conditions similar to those in the locality of the project. Coordinate harvesting and planting operations to prevent exposure of sprigs to the sun for more than 30 minutes before covering and moistening. Sprigs containing weeds or other detrimental material or that are heat damaged will be rejected.

PART 3 EXECUTION

3.1 EXTENT OF WORK

Provide landscape construction maintenance to include a water tank truck with pump, irrigation equipment, hoses, nozzles, cleaning and adjustments, watering, weeding, pruning, stake and guy adjusting and other tools and equipment for all landscape areas and existing plant material, unless indicated otherwise, and at all areas inside or outside the limits of the construction that are disturbed by the Contractor's operations.

3.2 JETTY TREE REMOVAL

Trees removed from the jetty must be stored on-site and placed along the foredune escarpment and along the jetty root upon completion of the work as shown on the drawings. Place trees prior to any hydromulching or plantings.

3.3 SITE PREPARATION

3.3.1 Soil Preparation

a. Areas to be seeded will be considered a satisfactory seedbed without additional treatment if it has recently been thoroughly loosened and worked to a depth of not less than 6 inches as a result of grading operations and, if immediately prior to hydroseeding, the top 3 inches of soils is loose, friable, and is shaped to the required grade.

b. Clear areas to be seeded and planted of gravel, stones, clods, rocks, roots, or other undesirable matter larger than 6 inches as a result of grading and staging operations. Place a maximum of 50 single pieces of woody debris throughout staging area to provide diversity to the landscape. Place prior to hydroseeding and a minimum of 100 feet apart and as approved by the CO.

SECTION 32 90 00.00 25 Page 7

c. Roughen all areas to be hydroseeded with equipment tracks, disc, ripper tooth, or other means approved by the CO before application of hydroseed.

d. Repair damage caused by erosion or other means after initial site preparation. This may include filling gullies, smoothing irregularities and repairing other incidental damage.

e. Seeding and hydromulching must not be done in the presence of free surface water resulting from rains, melting snow, tidal influence or other causes.

3.3.2 Woody Debris Areas

Place woody debris scattered across site as shown on drawings and directed by Contractor's licensed landscape architect and approved by CO.

3.4 SPRIGGING INSTALLATION

The sprigging method shall be Row Sprigging or other approved method.

Sprigging procedure must ensure even coverage. Dune Grass Sprigs must be planted in 18 inches on center triangular spacing and a minimum 2 inch depth, with mechanical sprig planter or other methods.

3.5 HYDROSEEDING

3.5.1 Hydroseeding Dates

Revegetation must be installed within 14 days of completion of site work as indicated on drawings, or as directed by CO.

3.5.2 Hydroseeding Process

Hydroseeding will be accomplished as a two-stage process. Apply the seed in the first step with a light layer of wood fiber hydromulch consisting of a minimum of 500 lbs per acre (and no greater than 700 lbs per acre) of wood fiber mulch plus tackifier (5-10 percent of mulch, according to manufacturer's specification) and dye. A full layer of wood fiber hydromulch consisting of a minimum of 1,500 lbs per acre plus tackifier and dye will be applied in the second step. Do not use fertilizer for the native seed mix hydroseeding. Do not use cellulose mulch.

3.5.3 Application

Apply the hydromulch slurry with or without seeds by aiming the nozzle upward rather than directly at the soil, so that the slurry does not hit the soil surface with full force. Maintain a continuous agitator action, that keeps the mulching material and tackifier in uniform suspension, throughout the distribution cycle. The pump pressure must be capable of maintaining a continuous non-fluctuating stream of slurry. The slurry distribution lines must be large enough to prevent stoppage and the discharge line must be equipped with a set of hydraulic spray nozzles that must provide an even distribution of the mulch slurry to the seedbed.

Ensure the application is uniform and at the prescribed rate, free of misses and overlapped areas. Cover a minimum of 95 percent of the soil surface area with hydromulch. Cure a minimum of 24 hours before rain events or irrigation and install per manufacturer's instructions, modified to incorporate the above-noted requirement of two separate application
