Planting Operations. Plant using the method called for on the details and plan sheets. Before beginning planting of each area, have available the necessary materials including prepared plant topsoil (see Subsection 893.2.07), water, stakes, and mulch. Plants shall be installed as straight/upright as possible. Any plants found to be leaning or broken will not be accepted or paid for by the engineer. When seasonal limitations and weather conditions permit, continuously water, mulch, guy, provide tree guards, and stake as indicated on the plans and details until completing the last operation. After completing planting, provide a method for retaining water adjacent to the plant according to the details shown on the Plans or as directed by the Engineer. Protect xxxxx restoration areas from vehicles and machinery. Typical protective barriers are not to be used in tidal areas. Stakes that remain secure and are taller than the highest tide, flagged with highly visible flagging tape, are required to mark the area to be protected and off-limits for vehicles and machinery. 1. Planting By the Pit Method a. Placing Bare-Rooted Plants Plant bare-rooted plants delivered to the pit area. Protect roots from drying out until placing them in the pit. 1. Center plants in pits and spread roots as they originally grew. 2. Cover and prepare the topsoil according to details shown on the Plans. b. Placing Balled and Burlapped Plants Immediately plant these plants after they are delivered to the pit site. 1. The pit diameter shall be a minimum of 3 times the diameter of the rootball. Center the ball in the prepared pit, leaving the top of the ball 1 in (25 mm) above the top of the ground for settlement. 2. Cut away and remove the top 1/3 of burlap from the rootball. Cut all ropes and twine, pull the nails, and drop the remaining burlap to the bottom of the hole. Cut away and remove all wire from the root ball. 3. Partially fill the pit with prepared plant topsoil and compact the soil enough to hold the ball firmly. Add mycorrhizal innoculant to plant topsoil if specified in plans. c. Placing Container-Grown Plants When the container is delivered to the pit site, split the container from top to bottom and carefully remove the plant. 1. The pit diameter shall be a minimum of 3 times the diameter of the rootball. Spread into the hole any major roots growing around the container or prune them to remove any circular growth. 2. Place the ball in the center of the prepared pit, leaving the top of the ball 1 in (25 mm) above the top of the ground for settlement. 3. Partially fill the pit with prepared plant topsoil and compact the soil enough to hold the ball firmly. Add mycorrhizal innoculant to plant topsoil if specified in plans. d. Completing Pit Plantings After placing pit plantings, water plants thoroughly the same day regardless of weather or soil moisture conditions. 1. After the water has soaked in, add prepared plant topsoil and compact firmly up to 2 in (50mm) below the adjacent ground. 2. Stop compacting when the compacted prepared topsoil is 2 in (50 mm) below the adjacent ground. 3. Fill the remainder of each pit with loose, prepared plant topsoil according to the details shown on the Plans. 4. Prepare the loose topsoil to retain water adjacent to the plant according to the Plans or as directed by the Engineer.

d. Completing Pit Plantings After placing pit plantings, water plants thoroughly the same day regardless of weather or soil moisture conditions.
1. After the water has soaked in, add prepared plant topsoil and compact firmly up to 2 in (50mm) below the adjacent ground.
2. Stop compacting when the compacted prepared topsoil is 2 in (50 mm) below the adjacent ground.
3. Fill the remainder of each pit with loose, prepared plant topsoil according to the details shown on the Plans.
4. Prepare the loose topsoil to retain water adjacent to the plant according to the Plans or as directed by the Engineer.
e. Live Stake Plantings
1. Plant live willow stakes at four (4) –foot (1.2m) intervals or as indicated on the drawings with the buds facing upward.
2. Eighty (80) percent of the stake shall be installed below ground, leaving twenty (20) percent extending above ground.
3. Stakes shall be placed deep enough to reach the water table during the dry season at an angle perpendicular to the slope.
4. Pack soil firmly around the hole after installation.
5. Install live willow (Salix spp.) stakes only in the dormant season, according to the planting details and landscape plan notes.
6. Replace any live stakes that split during installation.
2. Planting using a Xxxxxx, Hoedad, or Reinforced Planting Shovel for Bare Root Seedlings or wet- swale plants. Planting shall only be done when there is adequate moisture in the ground and when the ground is not frozen. Provide proper root positioning and contact with the soil, and eliminate all air pockets around roots. Roots of seedlings shall not be pinched or bent in a sideways or upturned direction. Each tree or wet-swale plant shall be inserted into the hole such that the root collar of the tree will be at ground level after backfilling is complete. Allowance for burying the root collar below ground level shall not exceed one-half inch in depth. In no case shall planting result in the root collar remaining above ground level. The soil back-filled around the root system shall be compacted sufficiently to support the sapling or wet-swale plant. Mow or use a string trimmer to a height of 1 in (25 mm) in the area designated for restoration. Do not mow wet swale in areas where standing water is present. Grass the area designated for a riparian seed mix and apply wheat straw mulch to the area before planting seedlings. Do not apply mulch to the wet-swale area. Plant within 48 hours after mowing or string trimming the site.
3. Restoration and enhancement of tidal xxxxx areas are subject to possible wave energy, requiring the use of a plant anchor for each plant. See planting plan sheets and details for plant anchor and anchoring descriptions.
