GENERAL NOTES

DESIGN: This structure is designed for HL-93 live loading in accordance with AASHTO LRFD Bridge Design Specifications, 8th Edition.

HYDROLOGY AND HYDRAULICS: This structure has been designed to pass a Q100 flood event with more than 5' of freeboard from upstream side of bridge. Flow data is provided on Sheet 6.

SPECIFICATIONS: Construct the project in compliance with Federal Highway Administration Standard Specifications for Construction of Road and Bridges on Federal Highway Projects (FP-14) and applicable Forest Service Supplemental Specifications.

ROAD WORK: Depths of all materials are given as final compacted depths. Remove all berms, existing or created, unless designated to remain, to allow drainage of water from the traveled way.

DEWATERING & EROSION CONTROL PLAN: Submit a dewatering and soil erosion and sediment control plan to the contracting officer for approval at least fifteen (15) days prior to beginning work. See Section 157 of the Supplemental Specifications, the notes on Sheet 7, and the general requirements shown on Sheet 13. Construct temporary means to divert the flow of the live stream as necessary to perform work.

Do not pump water from excavations directly into the live stream.

DISPOSAL: All materials designated for removal become the property of the contractor and are to be disposed of by removing from the forest in an environmentally safe manner in accordance with all local, state and federal requirements. Dispose of excess or unsuitable material at the location designated in FSSS Section 105. Hauling of excess or unsuitable material is incidental to associated work.

TEMPORARY TRAFFIC CONTROL: Submit a temporary traffic control plan to the Contracting Officer for approval at least 30 days prior to intended use.

IN-STREAM WORK: All in-stream work will be done between June 15th and September 1st. Allowance shall be given to the Forest Service to capture and remove fish and other aquatic organisms from within the construction work area prior to and during work activities.

EQUIPMENT STORAGE: Storage of all equipment on government lands will be at a location approved by the CO.

SEEDING: Seed and mulch all disturbed soil that is not within travel way or stream channel. Use Tongass Seed Mix. See FSSS Section 625.

STRUCTURE EXCAVATION NOTES:

1. Complete structure excavation in accordance with FP-14 Section 208.

2. Limits of excavation are shown for information purposes only. The contractor is solely responsible for excavation support and compliance with all applicable OSHA regulations.

3. Notify the CO immediately if bedrock or soft, unsuitable soils are encountered.

4. The estimated volume of structure excavation is based on the excavation limits shown in structure excavation section above. This quantity does not include any streambed simulation of earthwork necessary for stream channel re-grading.

DEWATERING AND SOIL EROSION CONTROL NOTES:

1. Protect against soil erosion and sedimentation during construction in accordance with

FP-14 Section 157, the project permits, Forest Service Handbook (FSH) 2509.22, Region 10 BMPs for Erosion Control, and the Guidance for the Invasive Plant Managment Program (Krosse 2017). Prepare and submit a soil erosion and sediment control plan to the CO for approval.

2. Dewater the excavation in accordance with FP-14 Sections 208 and 157 and the requirements on sheet 13.

3. Contractor should anticipate water infiltrating the excavations.

4. Structure excavation, riprap and rock rib placement, and backfill are to be completed in accordance with the Contract Specifications. Standing or running water in the work area does not relieve the contractor from meeting the specifications.

5. Dewatering is the sole responsibility of the contractor. Develop and submit to the CO a project-specific dewatering and sediment control plan with the excavation plan for approval. Sheet 13 illustrates the general dewatering requirements and possible methods and equipment and is not considered adequate or complete for this project.

Develop and submit a project-specific dewatering plan including drawings and a written outline illustrating and describing proposed layout, methods, and equipment. See sheet 13 for dewatering flows during construction. Approval of the contractor's dewatering plan does not relieve the contractor from completing the work as required. If the contractor's methods are not producing adequate results, the contractor must re-evaluate and submit another dewatering plan. Re-submittal of the dewatering plan, if required, is incidental to the work.

STRUCTURE BACKFILL NOTES:

1. Structural Backfill limits shown here are the minimum requirements. Place

Structural Backfill in accordance with FP-14 Section 208, and as shown on these Plans, with material meeting the requirements of Subsection 704.04.

Compact Structural Backfill material in accordance with FP-14 Subsection

208.10. Any material outside the Structural Backfill limits shown is considered Road Embankment and the material must meet the requirements of FP-14 Subsection 704.06.

2. It is assumed that material conserved from the structure excavation at this site will meet the requirement for Structural Backfill (704.04) or Road Embankment (704.06). Some mixing and sorting may be required to meet the material specification. Haul and dispose unsuitable and excess material to the designated waste site. Haul and disposal of unsuitable and excess material is paid with Item 20806.

FOOTNOTES:

1 The final channel bottom should be a dense, well interlocked streambed with low permeability.

Compact each layer and fill surface voids by washing in fine material. Use water pressure, tamping rods, and similar hand operated equipment to force fine material into all surface voids.

THE CONTRACTOR IS RESPONSIBLE TO ENSURE THAT THE STREAM FLOW DOES NOT GO

SUBSURFACE THROUGH THE CULVERT FOR A 48 HOUR PERIOD AFTER RE-WATERING.

Native material meeting the gradation for the specified Bed Class, and Channel Rock may be salvaged and incorporated into the simulated streambed.

Rock Weir placement is 1'± from designated station shown in profile. The spacing and configuration of rock weirs maybe adjusted in the field by the CO to fit actual streambed conditions.

Bypass pipe

Downstream sump pump place in cutoff trench or sump at depth needed to dewater excavation

NOTES:

1. Design dewatering flow for construction is 130 CFS.

2. The plan shown here is intended to represent the general dewatering requirements and not applicable to a specific site.

submit a plan specific to the site.

3. Contractor to determine the size of the bypass pipe based on the specified flow.

4. Ensure that the bypass pipe and dam are leak-proof. Do not proceed with construction until the implemented dewatering plan has been inspected and accepted by the CO in writing.

5. Ensure pumps are be clean and free of leaks and placed in a containment kit.

6. Excavate draw down pool for sumps a minimum of 2 feet below the bottom of the excavation and a minimum of 5 feet in diameter.

7. Maintain all elements of the operation in order to dewater the foundation, facilitate construction, prevent harm to aquatic organisms (not just fish) and prevent sediment and turbidity from entering the stream. Construct the dewatering system in a manner which enables USFS biologists to collect and transport organisms from the live channel, just before completion of the diversion dam.

8. Operate pumps (preferably electric) downstream of the bypass dam if the dam does not seal thoroughly. Maintain a pump running 24 hours a day in the downstream sediment retention dam to divert water containing sediment to the forest floor where it will be filtered before entering back into the stream.

Leave pumps in position on site even if water discharge drops considerably, to be prepared for storm flows.

Provide ditches and/or sumps as necessary to form channel and place stream features
