160.1General Description
This work includes reclaiming material pits and waste areas by vegetative planting and applies to areas outside of the right- of-way. The vegetative requirements of this section apply when the Contractor obtains material from a source or wastes material on an area other than within the Right-of -Way. These requirements apply regardless of how the source or area is obtained. Exceptions to the vegetative requirements of this section include: •A material source where the Engineer determines not to drain water that accumulates after the material isremoved. Only the slopes above water will be planted. •An area composed of rock or other materials that the Engineer determines are not satisfactory for per manent v egetative cover. •An area that has been exempted in writing by the Georgia Surface Mined Land Use Board. •An area where the owner or Contractor, (whichever is designated as the Operator) secures a license from the S urface Mined Land Use Board for surface mining. The Operator will be responsible only to the Surface Mined Land Use Board for reclamation of the affected area. 160.1.01 Definitions General Provisions 101 through 150. 160.1.02 Related References A.Standard Specifications

B.Referenced Documents General Provisions 101 through 150. 160.1.03 Submittals The Engineer must: •Approve the planting type if the Contractor furnishes a material pit or waste area that requires vegetatio n u nder the provisions of this specification. •Approve all modified mixtures before planting begins. The property owner may change the plant material types specified in the Plans to a type not shown in the Planting Table in Subsection 160.2, Planting Table , below. If a change is made, the mixture shall cost approximately the same and shall produce an equal amount of protective covering as the mixture contained in this specification. 123 123 123 123 123 123 123 123 123 123
160.2Materials
Materials shall conform to the requirements of Sections 700 and 702 as applicable. If the Plans or the Proposal do not specify the vegetation type to be planted on State -optioned areas, the Engineer will select the type to be used on each area from the Planting Table. The State is divided into planting zones as shown on the Planting Zones Map in Sections 700. Consult the Planting Table when planting and follow these points: • Do not use giant bermuda seed (cynodon species) including NK -37. • Do not use Italian rye grass seed —perennial or annual. • Apply the entire combination of seeds specified for each group in the amounts specified. If the property owner does not make a specific choice, use planting groups A, B, C, G, H, or N- 1. • Increase all seed quantities 50 percent on slopes that ar e too steep for soil preparation and cannot be dug at least 6 in. (150 mm) deep. • Air dry sericea lespedeza seed hay and ensure that it contains mature seed.

3.Harvest sprigs as follows: a.Harvest the sprigs using a sod cutter, turning plow, or other approved equipment so that at least 3 in . ( 75 mm) of the root system is lifted intact. b.Immediately load the harvested sprigs and cover them with wet burlap or canvas to prev ent weather damage. c.Transport the sprigs to where they will be immediately planted or stockpiled. d.Plant sprigs within 48 hours after they are harvested. Never allow spr igs to dry out or freeze. H.Apply Sprigs Apply sprigs using either the broadcast or row method. However, do not perform broadcast sprigging on stee p s lopes or narrow areas where results will not be satisfactory. During sprigging, ensure that the soil moisture content is at least the optimum for soil sprigging. 1.Broadcast Sprigging Perform broadcast sprigging as follows:a.Apply the sprigs mechanically or by hand in a uniform layer over the prepared surface placing at leas t viable sprigs to each square foot (43 viable sprigs to each square meter). b.Place the sprigs 2 to 3 in. (50 to 75 mm) deep by disc harrowing or by other satisfactory means. 2.Row Sprigging 3.Perform row sprigging as follows:a.Open furrows spaced at least 1 ft. (300 mm) apart to at least 4 in. (100 mm) deep. b.Immediately place the sprigs in the furrows by hand or by planting machines and overlap them i n the furrows. c.Do not expose sprigs more than 15 minutes before filling in the furrows. I.Restore Line and Grade, and Roll After the sprigging is done, do the following: 1.Return the impaired sections back to the line and grade as established by the Engineer. 2.Roll the area at right angles to the direction of the slope incline. J.Mulch Spr igged Areas Mulch sprigged areas within the construction limits according to Subsection 700.3.05.G, Mulching . 1.M ulch with Binder When applying mulch with binder, apply immediately after the over -seeding and rolling are complete. 2.Mixed -in-Place Mulch When applying mixed -in-place mulch, apply immediately after sprigging. 160.3.06 Quality Acceptance Before Final Acceptance, each planted area shall meet the requirements for satisfactory growth and development as defined in Subsectio n 160.5.01.A, Plant Establishment . Except as otherwise specified in this specification, all seeding shall conform to Section 700, and pine seedling planting shall conform to Section 702. 160.3.07 Contractor Warranty and Maintenance General Provisions 101 through 150.

B.Pine Tree Seedlings The area covered with pine tree seedlings will not be considered satisfactory until 85 percent or more of the g rowth has survived 90 days after planting with no fail spots exceeding 0.25 acre (0.1 ha). If the survival rate is less than 85 percent, but greater than 75 percent, and fail spots do not exceed 0.25 acre (0.1 ha), the affected area will be measured for payment at half the Contract price unless the Contractor r eplants the deficient area to meet the requirements for full growth and coverage. Areas that do not meet the minimum 75 percent requirement shall be replanted in full at the Contractor’s expense. All replanting shall be done within the allowable planting season for pine seedlings as shown in Subsection 160.2, Planting Table . 130 130 130 130 130 130 130 130 130 130
