1. See Section 01 31 00 “Project Management and Coordination” for requirements on using the Project Website.

B. San Juan Island National Historical Park (SAJH) contains areas of significant natural and cultural resources that shall be protected during construction of improvements within the park boundary.

The Contractor shall conform to the requirements set forth in these specifications to protect identified, suspected, or discovered natural and archeological resources within the project limits.

Additional requirements may be described in other specification sections.

C. Orientation Training: All Contractor and subcontractor employees shall receive a brief orientation about working in San Juan Island National Historical Park prior to actually performing work. The orientation will describe the efforts to be taken by the Contractor and subcontractor employees to protect the natural, archeological and physical resources of SAJH while working on this and other projects. This orientation will also describe mitigation and other environmental protection measures that must be adhered to at all times while in the Park. The Contractor shall maintain a manifest tracking all contractor personnel, when they received their orientation training, and when they started work. Contractor personnel shall be field identifiable as having received their orientation training by means of a readily visible sticker on their hard hat. Orientation training shall be coordinated with the Contracting Officer.

D. The Contractor shall minimize environmental pollution and damage that may occur as the result of construction operations. The environmental resources, including natural, cultural and physical resources, within the project boundaries and those affected outside the limits of permanent work shall be protected during the entire duration of this contract. The Contractor shall comply with all applicable environmental Federal, State, and local laws and regulations. The Contractor shall be responsible for compliance with this section by its employees and its subcontractor employees.

The Contractor shall be responsible for any delays resulting from failure to comply with environmental laws and regulations.

E. The Contractor shall ensure those involved with the project act positively to protect the environment, both on-site and off-site, during all construction operations. All activities and requirements of a general nature described in this section are applicable to all areas within the San Juan Island National Historical Park boundary.

F. Natural Resource Protection

1. Plant Condition Inventory: The Contractor and the CO shall perform an on-site inventory of trees and other overall vegetation features within or near to the work limits. A print of the contract drawings showing tree locations and a photo record will be used to note

SAJH - 152762 01 11 00 - 5

condition of trees and vegetation. This annotated drawing will be retained by the CO for use during the final walk-through and tree/vegetation assessment. This walk through shall be a part of the project closeout requirements (see Section 01 77 00, Closeout Procedures).

2. On-site inventory shall be scheduled in coordination with the pre-construction conference.

3. Provide temporary barriers (e.g., orange construction fence) to protect existing trees, plants and critical root zones that are designated to remain, but are: (1) within the construction limits; 2) on or just outside the construction limits; (3) within the clearing limits (i.e., the zone extending 5 feet beyond the staked construction limits); or (4) on, or just outside the clearing limit line. Barriers shall be in place before construction begins.

4. Trees, shrubs, vines, grasses, and other vegetative features indicated and defined on the Drawings to be preserved shall be clearly identified by marking, fencing, or any other approved techniques. The Contractor shall restore vegetative features damaged or destroyed during construction operations outside the limits of the approved work area.

5. Except in areas indicated on the drawings or specified to be cleared, the Contractor shall not remove, cut, deface, injure, or destroy resources including trees, shrubs, vines, grasses, topsoil, and landforms without approval. No ropes, cables, or guys shall be fastened to or attached to any trees for anchorage unless specifically authorized.

6. Should removal of additional trees or tree roots be requested, Contractor shall notify the CO who will coordinate an inspection and determination by the appropriate authorities whether to remove the tree or not.

7. After tree removal, large roots may remain in the ground. Contractor shall be responsible for carefully removing in-ground tree roots of removed trees to permit excavation, drilling, or other ground penetrating construction activities. During tree root removal, do not use backhoes, chains, or other equipment in a manner that will harm roots of adjacent trees.

8. Minimize disturbance to tree trunks and root zones to prevent damage to trees.

9. Adjust trenches and other excavations to keep them beyond the drip line wherever possible.

10. Steps to Mitigate Damage to Roots Due to Excavation:

a. Take steps (as called for below) to mitigate damage to tree roots during excavation, wherever excavation must take place within the drip line of trees of all trees 12 inches or larger in diameter.

b. Trees which are anticipated to meet these criteria and therefore require steps to mitigate damage to roots due to excavation are shown on the drawings. Adjustments in trench alignment or other factors may result in variations in which trees are affected. The Contractor shall accommodate these variations at no additional expense to the Government.

c. Following are the steps which are required to mitigate damage to roots due to excavation:

1) Excavate carefully where tree roots might be encountered. Where roots 2 inches and larger are encountered, hand excavate as required to prevent damage to roots. Tunnel under roots to be saved, hand excavating as necessary.

2) Do not cut roots over 2-inch-in-diameter without approval of CO.

3) Cleanly saw-cut roots between 1-inch and 2-inch-in-diameter where they interfere with work; do not cut roots except as necessary. Roots between 1-inch and 2-inch-in-diameter which must be cut shall be cleanly saw-cut near the edge of trench closest to the tree to prevent roots from being dislodged from soil by equipment.

SAJH - 152762 01 11 00 - 6

d. If trenching will occur within 18" of the trunk of trees that do not meet the criteria under paragraph 1.8.F.10 above, the tree/shrub shall be removed from the construction area and replanted in its original location. Plants shall be removed by certified nursery personnel or arborist, with their roots pruned and balled as appropriate for their size.

11. Avoid soil compaction within plant root zones with heavy equipment and vehicles within the project work limits.

12. Do not cut wheels or make sharp turns with wheeled or tracked equipment in root zones.

13. Do not pile excavated soil against tree trunks.

14. Do not mechanically compact soils in undeveloped areas except to meet minimum compaction requirements as approved by the CO.

15. Maintain original soil topography in plant root zones whenever possible.

16. Preserve tree snags where feasible as potential bat or bird habitat.

G. Plant Appraisal

1. If the Contractor destroys or injures trees and vegetation designated for protection or outside the work limits, the Contractor will be assessed damages prior to final progress payment.

2. Replacement costs for damaged vegetation will be computed according to the method described in the International Society of Arborculture’s 1992 Guide for Plant Appraisal.

This method is based on the cost of the largest commonly available tree or shrub, with modifications based on species value, condition, and location. A trained arborist or professional plant appraiser from the Washington region will be hired by the NPS to make the damage appraisal. The arborist’s fees will be included in the damage assessment.

3. This damage appraisal process will be triggered by any of the following types of damage to vegetation outside the work limits or unauthorized disturbance of vegetation within the work limits.

a. Removal of any tree or shrub.

b. Pruning or removal of more than 30 percent of a tree or shrub canopy.

H. Protection from Exotic Plant Species

1. Measures shall be taken to prevent the introduction of exotic species in the project area and staging areas. All earth moving equipment must enter the Park free of dirt, dust, mud, seeds, or other potential contaminant. Equipment exhibiting any dirt or other material attached to frame, tires, wheels, or other parts shall be thoroughly cleaned by the Contractor before entering the Park per Section 01 50 00 3.4.B. All equipment shall be inspected prior to moving onto Park property per Section 01 50 00 3.4.B. Areas inspected shall include, but not be limited to, tracks, track guard/housings, belly pans/under covers, buckets, rippers, and other attachments. Equipment that does not pass inspection will be turned around to the nearest cleaning facility outside the park. If vehicles are unable to drive to the inspection location due to size or load restrictions, vehicles will be inspected at a mutually agreed site by the CO prior to entering the Park. The Contractor shall notify the Construction manager at least two work days (not including weekends) prior to bringing any equipment into the Park. Equipment found to have entered the Park with potential contaminants will be removed from the Park at the direction of the CO at Contractor’s sole expense.

2. Minimize ground disturbance to the greatest extent possible.

SAJH - 152762 01 11 00 - 7

3. The contractor shall get approval in writing from the CO for fill material that must be used in a way or stored in a location not clearly specified in the contract.

4. Fill materials used within the top 12 inches of finished grade are required to be free of exotic and noxious weed species and shall have the source locations approved by the CO.

The Contractor shall submit to the CO a list of proposed sources for imported fill materials requiring certification 30 calendar days in advance of importing material. The presence of noxious weed species is grounds for rejection of the source. If exotic weed species are found or suspected, the Contractor may be required to strip the top 12 inches of source material and only import sub-surface material and/or sterilize the material, at the CO’s discretion. The presence of the following particularly noxious weed species are grounds for rejection of the source: spotted knapweed, yellow star-thistle, perennial pepperweed, broom species, and other species on the Washington State List of Noxious Weeds. If spraying is required, the Contractor shall provide a licensed operator to spray according to applicable state regulations. The Contractor shall not spray any herbicides until approved in writing by the CO.

5. Drain and flush all pumps, tanks, live wells, buckets and other containers that might carry water contaminated with exotic plants and animals, such as the zebra mussel, prior to bringing equipment into the park. Thoroughly wash all hauling tanks and equipment using a hard spray from a garden hose. If equipment was used in infested waters, use the following steps to clean the equipment:

a. Wash with hot water (140 F or 40 C) or a high pressure washer (250 pounds per square inch). Remove all aquatic weeds – they can carry zebra mussels.

I. Wetlands Protection

1. The Contractor shall fence construction areas adjacent to aquatic habitats to prohibit the movement of aquatic species into the construction area and to control siltation and disturbance in aquatic habitats.

2. The Contractor shall salvage and reuse wetland soils as fill to the maximum extent possible.

3. The Contractor shall use trench plugs where designated on the drawings in wetland areas to prevent changes to natural flow patterns.

4. During dewatering, intakes shall be completely screened with wire mesh not larger than 5 millimeters to prevent aquatic species from entering the pump system.

5. Access routes to and through work locations in the meadows and wetlands shall be planked with 1 1/8" plywood, stabilization mats or other method approved by the CO.

J. Fish and Wildlife Protection

1. The Contractor and Contractor’s employees shall not feed any animals within San Juan Island National Historical Park.

2. The Contractor shall make all reasonable efforts in accordance with the plans and specifications for the protection of threatened or endangered or candidate species including their habitat in accordance with Federal, State, Regional, and local laws and regulations.

3. Contractor shall maintain routes of escape from excavated pits and trenches for animals that might fall in. During construction activities, Contractor personnel shall maintain vigilance for animals caught in excavations and take appropriate action to free them.

Excavation pits shall have a ramp or incline at either end to allow for human and wildlife escape.

4. Bald Eagle Mitigation

SAJH - 152762 01 11 00 - 8

a. Keep a distance between the project activity and the nest: the existing buffer distance between the nest and the new visitor center facilities would be maintained, and the construction staging area would be located at the far eastern side of the parking area, in order to be as far away from the nest as possible.

b. Maintain preferably forested (or natural) areas between the project activity and around nest trees: as few mature trees as possible, including existing trees that provide screening between the nest and visitor center, would be removed. The nest tree and immediately adjacent trees that provide existing canopy coverage would be protected.

c. Avoid certain activities during the breeding season: the loudest activities (excavation, tree removal, demolition, and construction) and those activities taking place closest to the nest would be initiated in the late summer or early fall, thus avoiding the nesting season (January through mid-August).

5. Migratory Birds Mitigation

a. Vegetation removal shall occur outside of the nesting season for migratory birds, typically early April through mid-July.

K. New Utility Services to Site

1. Contractor shall coordinate the installation of a new power service onto the site with Orcas Power & Light Co-Op (OPALCO), Glen Brozio, 360-376-3500. OPALCO will install a new 1 phase power service onto the site. Contractor shall coordinate work schedule with OPALCO to prevent delay to Contractor work tasks.

2. Contractor shall coordinate the installation of new communication services onto the site with Rock Island Communications, 360-378-5884 and Century Link. Contractor shall coordinate work schedule with Rock Island Communications and Century Link to prevent delay to Contractor work tasks.
