3.4 SODDING

A. Place sod according to TPI Guideline Specifications for sodding. Lay sod at right angles to slope or the flow of water. On slope areas, start at bottom of slope.

B. Finishing: After sodding, blend edges of sod smoothly into surrounding area. Roll with lightweight roller to eliminate air spaces between sod and firmed soil.

3.5 WATERING

A. Watering: Start watering turfgrass areas immediately after installation at sufficient rate to ensure thorough wetting of soil to minimum 50 mm

(2 inches) deep. Supervise watering operation to prevent run-off.

Supply necessary pumps, hoses, pipelines, and sprinkling equipment.

Repair all areas damaged by water operations. Keep soil surface constantly moist, not wet, until turfgrass plants are well established.

3.6 EROSION CONTROL MATERIAL

A. Install and maintain erosion control material on designated areas as shown on drawings. Prepare, fertilize and vegetate areas to be covered, before erosion material is placed. Immediately following planting operations, lay erosion control material evenly and smoothly and in contact with soil throughout. Omit straw mulch from all seeded areas receiving erosion control material.

B. For waterways, unroll erosion control material in direction of water flow. When two or more strips are required to cover ditch area, overlap strips minimum 100 mm (4 inches). For strips to be spliced lengthwise, overlap ends minimum 150 mm (6 inches) with upgrade section on top.

C. On slopes, place erosion control material either horizontally or vertically to slope with edges and ends of adjacent strips butted tightly against each other.

D. Staple each erosion control strip in three rows (each edge and center with center row alternately spaced) with staples spaced maximum 1200 mm

(4 feet) longitudinally. For two or more strips side by side on slopes, install common row of staples on adjoining strips. Staple all end

32 90 00 - 6 strips at 300 mm (12 inch) intervals at end. Firmly embed staples in underlying soil.

E. Provide erosion control maintenance to repair damage by erosion, wind, or any other cause. Maintain, protect, repair, or replace erosion control material until Termination of the Plant and Warranty Period.

3.7 LANDSCAPE PLANT AND TURFGRASS ESTABLISHMENT PERIOD

A. Landscape Plant and Turfgrass Establishment Period: Begins immediately after installation, with COR's approval, and continues through growing season sufficiently long for turfgrass and landscape plant materials to become establish and provide satisfactory to District Agronomist and

NCA. Conditions and appearance are as follows:

1. Turfgrass has obtained minimum of 98 percent generally weed-free surface cover.

2. Maintain plant and turfgrass during establishment period.

3. Plants and turfgrass will not be accepted until completion of acceptable establishment period.

4. During Landscape Plant and Turfgrass Establishment Period complete the following:

a. Water plants and turfgrass to maintain moist soil surface until plants and turfgrass are well established.

b. Provide the following during turfgrass establishment:

1) Eradicate weeds. Water, fertilize, overseed, and perform other operation necessary to promote growth of turfgrass.

2) Mow turfgrasses as often as necessary to maintain

NCA specified mowing height for each type of turfgrass before final acceptance. Begin mowing when cool season turfgrass is

100 mm (4 inches) high.

c. Sod will be evaluated for species and health thirty (30) days after laying last piece and reevaluated each 15 days during the establishment period. A satisfactory stand of grass plants from sod operation will be living sod, uniform in color and leaf texture. Bare spots to be maximum 1250 sq. mm (2 sq. inches).

Joints between sod pieces to be tight and free of weeds and other undesirable growth.

d. Repair damage caused while making plant or turfgrass replacements.

32 90 00 - 7

3.8 LANDSCAPE PLANT AND TURFGRASS ACCEPTANCE

A. Criteria for Acceptance of Turfgrass:

1. Sod: Living sod grass plants uniform in color and leaf texture and well rooted into soil below so that gentle pulling of turfgrass leaves by hand does not dislodge sod. Bare spots to be maximum

1250 sq. mm (2 sq. inches). Joints between sod pieces shall be tight and free from weeds and other undesirable growth.

3.9 CLEANING

A. Remove and legally dispose of all debris, rubbish, and excess material from project site.
