3.4.1 General

The applicable seed shall be sown at the rate and time as indicated in the table below, unless otherwise specified in the approved Turf Establishment Plan. A method of sowing shall be employed; using approved mechanical power-drawn seeders, mechanical hand- seeders, broadcast-seeders, or other approved methods. When delays in operations extend the work beyond the most favorable planting season for the species designated, or when conditions are such by reason of drought, high winds, excessive moisture, or other factors that satisfactory results are not likely to be obtained, work shall be stopped as directed by the Contracting Officer's Representative and resumed only when conditions are favorable for turf establishment or when approved alternative or corrective measures and procedures have been completed. If inspection during or after seeding operations indicates that areas have been left unplanted or other areas have not been adequately addressed, additional seed shall be applied.

March 1 to September 1 hulled common Bermuda grass - 150 lbs (min) of PLS/acre or bermuda grass/seashore paspalum mix or bermuda grass/bahiagrass mix - 150 lbs (min) of PLS / acre

September 1 to March 1 Step 1 - annual, intermediate or perennial ryegrass-50 lbs (min) of PLS / acre to provide coverage during months when environmental conditions are not suitable for common bermuda grass establishment.

Step 2 - between March 1 and September 1 - hulled common bermuda grass - 150 lbs (min) of PLS/acre or bermuda grass/seashore paspalum mix or bermuda grass/bahiagrass mix- 150 lbs (min) of PLS / acre

SECTION 32 92 19.04 12 Page 10

Hulled Bermuda grass may be planted in the month of February if soil temperatures are in excess of 65 F for a minimum of 7 consecutive days.

PLS (Pure Live Seed) = (label germination rate x label purity) x

Example of how to calculate PLS PLS = (0.95 germination rate x 0.85 purity) x 100

PLS = 81 %

Therefore 1 lb PLS requires 1/0.81 = 1.23 lbs of seed

3.4.2 Broadcast Seeding

Seed shall be broadcast with approved sowing equipment and distributed uniformly over designated areas at the appropriate seeding rates. After broadcast seeding, seed shall be covered to an average depth of 1/4-inch using a brush, harrow, spike-tooth harrow, chain harrow, cultipacker, or other approved devices. In addition, after soil amending and seeding, the soil shall be compacted using a tractor drawn pull behind smooth drum roller or other approved equipment necessary to compact the soil to prevent erosion prior to mulching. Seed shall not be broadcast during windy or inclement weather.

3.4.3 Damage to Established Seeding Area

The Contractor shall be fully responsible for any damage to the establishment areas caused by his/her operations. Areas that become damaged as a result of poor workmanship or failure to meet the requirements of the specifications will be ordered repaired and reseeded to specification requirements, without any additional cost to the Government.

3.5 APPLYING AND ANCHORING MULCH

Application of mulch shall follow these guidelines unless otherwise specified in the approved Turf Establishment Plan. The mulch shall be vegetative non-asphalt mulch consisting of grain straw (oats, wheat, or rice) wood fiber or grass hay. Dry broadcast type mulch, as specified in paragraph "Mulch", shall be applied uniformly on the soil surface at the minimum rate of 2 tons (approximately 80 bales) per acre.

Hydrologically-placed mulch (applied at the rate specified in the Turf Establishment Plan but no less than 3,500 pounds per acre on levee slopes and crown and 2,000 pounds per acre on berms) shall be done immediately after seeding. Hydromulching will include an improved tackifier applied at the rate recommended by the manufacturer. Dry broadcast type mulch shall be tacked by spraying with emulsified tackifier at the rate of 150 gallons per ton of mulch, crimped or as recommended in the Turf Establishment Plan. The mulch and tackifier shall be applied by means of approved equipment.

3.6 WATER APPLICATION DURING TURF ESTABLISHMENT

Unless the Contracting Officer's Representative concurs that acceptable levels from precipitation have occurred to support grass establishment, watering operations will be conducted one to two days after seeding. Water shall be applied at least 2 times per week for a period of 28 days unless otherwise directed by the Contracting Officer's Representative. The application of water shall sufficiently moisten at least the top 2 inches of soil with each irrigation event. The application of water in excess, so that surface runoff occurs, is prohibited. The Contractor shall repair all

SECTION 32 92 19.04 12 Page 11 damaged areas, including tire ruts and repairs to seeded and mulched areas, caused by watering at no additional cost to the Government.

3.7 MOWING

3.7.1 New Turf Establishment Areas

Turf areas established under this contract shall be mowed with approved mowing equipment to a height of 3 to 4-inches whenever the height of the vegetation is in excess of 8 inches. Grass clippings created from mowing that will inhibit turf establishment shall be removed from the site. The Contractor shall perform periodic and final grass mowing within the limits of Right of Way until final inspection and acceptance.

3.7.2 Existing Turf Maintenance

For the duration of the contract, the Contractor shall maintain established turf within the limits of the work as shown on the drawings. Same requirements as paragraph New Turf Establishment Areas apply.

3.8 INSPECTIONS AND REPORTS

After initial planting, the Contractor shall inspect newly turfed areas at least once every two weeks. For each inspection conducted, the Contractor shall prepare a report summarizing the scope of the inspection, names of personnel making the inspection, inspection date, height of vegetation, observations and conclusions, maintenance performed, and corrective actions, if required. The report shall be furnished to the Contracting Officer's Representative within 24 hours of the inspection as a part of the Contractor's daily QC Report.

3.9 REPLANTING

The Contractor shall restore/repair any eroded areas or bare spots along the alignment in accordance with the requirements of this specification, all at no additional cost to the Government.

3.10 POST-PLANTING FERTILIZER APPLICATION

For those areas that do not require replanting, approximately one month after the initial planting, fertilizer shall be applied at the minimum rate of 50 lbs per acre using a slow-release nitrogen fertilizer formula, or at a rate as recommended in the Turf Establishment Plan. The fertilizer shall be applied with irrigation or rainfall occurring within 24 hours.

3.11 ESTABLISHMENT

Turf will be considered established and completed when the areas to be turfed have produced the required grass species, either Bermuda, Bahia or Seashore Paspalum, over a minimum of 75 percent of the entire area as determined by the Contracting Officer's Representative by random sampling.

Seventy-five percent coverage shall be confirmed by the use a 1 meter square constructed from PVC with 100 blocks of 100cm2 (10 cm grid).

Measurements shall be made on both sides of the levee every 100 to 250 feet. If 25 blocks of the 1-meter square are not filled with the intended vegetative species; that section of the levee shall be deemed unacceptable. Bare areas with diameters larger than 24 inches are to be considered unacceptable and shall be noted for repairs.

SECTION 32 92 19.04 12 Page 12

3.12 INSPECTION AND ACCEPTANCE

Acceptance inspections of the entire turfed area shall be performed by the Contracting Officer's Representative by random sampling and supplemented by visual inspections. If inspection determines that turf establishment is not complete, the Contractor shall meet with the Contracting Officer's Representative at the job site to identify bare spots, eroded areas and rutting damage and to discuss the Contractor's plan of operation for completing new turf establishment. Prior to acceptance of turfed areas by the Contracting Officer's Representative, the Contractor shall restore any damaged areas resulting from the Contractor's operations or by natural forces at no additional cost to the Government. Partial reaches will not be accepted unless determined by the Contracting Officer's Representative to be in the best interest of the Government.

3.13 INITIAL SEEDING AND FERTILIZING ACCEPTANCE

Provided all other features of work have been accepted and completed, and provided all work within the project limits have had initial seed, mulch, and fertilizer accepted, no liquidated damages will be assessed after acceptable completion of initial seeding, mulching and fertilization. The remainder of turf establishment requirements remain in force.
