2. Under turf or unpaved areas, scarify and recompact top 6 inches below subgrade and compact each layer of backfill or fill soil material at 85 percent.

3. For general utility trenches, compact each layer of backfill soil material at 85 percent.

4. For utility trenches under roadways (and utility patches), compact all backfill material in 6” loose lifts to 95 percent of the standard proctor per ASTM D698. Provide compaction testing documentation with at least 2 tests per layer.

3.12 SUBBASE AND BASE COURSES UNDER PAVEMENTS AND WALKS

A. Place backfill on subgrades free of mud, frost, snow, or ice.

B. On prepared subgrade, place subbase course and base course under pavements and walks as follows:

1. Place material that exceeds 6 inches in compacted thickness in layers of equal thickness, with no compacted layer more than 6 inches thick or less than 3 inches thick.

2. Compact material at optimum moisture content to required grades, lines, cross sections, and thickness to not less than 95 percent of maximum dry unit weight.

3.13 DRAINAGE COURSE UNDER CONCRETE SLABS-ON-GRADE

A. Place drainage course on subgrades free of mud, frost, snow, or ice.

3.14 FIELD QUALITY CONTROL

A. Testing Agency: Owner reserves the right to engage a qualified testing agency to perform tests and inspections.

B. Allow testing agency to inspect and test subgrades and each fill or backfill layer if applicable. Government may reject work found to not comply with contract requirements.

3.15 PROTECTION

A. Protecting Graded Areas: Protect newly graded areas from traffic, freezing, and erosion. Keep free of trash and debris.

B. Repair and reestablish grades to specified tolerances where completed or partially completed surfaces become eroded, rutted, settled, or where they lose compaction due to subsequent construction operations or weather conditions.

C. Where settling occurs before Project correction period elapses, remove finished surfacing, backfill with additional soil material, compact, and reconstruct surfacing.

1.5 METHOD OF MEASUREMENT

A. Seeding and Mulching is incidental to the project work unless otherwise specified.

PART 2 – PRODUCTS

2.1 PLANTING MATERIALS

A. Topsoil Source: Reuse surface soil on-site or import where not available on site. Topsoil source must be approved by COR. B. Seed Mix:

1. Spring & Fall Planting:

Roundstone Native Seed - Mix 208 - Southern Quick Erosion Control Cover Mix Or COR Approved Equivalent

2. Summer Planting:

Roundstone Native Seed - Mix 209 - Southern Quick Erosion Control Cover Mix Or COR Approved Equivalent C. Mulches:

1. Straw Mulch: Provide air-dry, clean, mildew- and weed-free, threshed straw of wheat, rye, oats, or barley.

A. Finish Grading: Grade planting areas to a smooth, uniform surface plane with loose, uniformly fine texture. Grade to within plus or minus 1/2 inch of finish elevation.

Roll and rake, remove ridges, and fill depressions to meet finish grades. Limit fine grading to areas that can be planted in the immediate future.

B. Restore areas if eroded or otherwise disturbed after finish grading and before planting.

3.2 SEEDING

A. Sow seed at the rate of 15lb/acre. Apply Fertilizer at rate required by contract documents, if required by contract documents.

B. Rake seed lightly into top 1/8 inch of topsoil, roll lightly, and water with fine spray.

C. Protect seeded areas by spreading straw mulch. Spread uniformly at a minimum rate of 2 tons/acre to form a continuous blanket 1-1/2 inches in loose depth over seeded areas. Spread by hand, blower, or other suitable equipment. Straw mat netting shall be installed according to manufacturer’s recommendations. D. Hydro-seeding using the above seeding rates is also acceptable method of seeding.

E. Seeding shall be completed between April 1-June 1 for spring plantings and Sept.1- October 15 for fall planting.

F. Temporary seeding during winter months may be required and shall consist of winter wheat at 30lb/acre and straw mulch at one ton per acre.
