GENERAL NOTES
DESIGN: THIS STRUCTURE IS DESIGNED FOR HL-93 LIVE LOADING IN
ACCORDANCE WITH AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS, 7TH
EDITION.
HYDROLOGY AND HYDRAULICS: THIS STRUCTURE HAS BEEN DESIGNED TO
PASS A Q100 FLOOD EVENT WITH A HEADWATER DEPTH TO CULVERT RISE
RATIO LESS THAN 0.8. FLOW DATA IS PROVIDED ON SHEET 5.
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

2. 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.
STRUCTURE BACKFILL NOTES:
1. PLACE BACKFILL IN ACCORDANCE WITH FP-14 SECTION 209 WITH MATERIAL
MEETING THE REQUIREMENTS OF SECTION 704.03. SUITABLE MATERIAL
SALVAGED FROM THE EXCAVATION MAY BE USED TO BACKFILL THE CULVERT.
HAUL AND DISPOSE UNSUITABLE MATERIAL TO THE DESIGNATED WASTE SITE.
HAUL AND DISPOSAL OF UNSUITABLE MATERIAL AND IMPORTING REPLACEMENT
MATERIAL IS PAID WITH ITEM 20411.
2. BACKFILL LIMITS SHOWN HERE ARE THE MINIMUM REQUIREMENTS.
3. COMPACT BACKFILL MATERIAL IN ACCORDANCE WITH FP-14 SECTION 209.10.
DEWATERING AND SOIL EROSION CONTROL NOTES:
1. PROTECT AGAINST SOIL EROSION AND SEDIMENTATION DURING CONSTRUCTION IN
ACCORDANCE WITH FP-14 SECTION 157 AND THE PROJECT PERMITS. 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 9.
3. CONTRACTOR SHOULD ANTICIPATE WATER INFILTRATING THE EXCAVATIONS.
4. CULVERT EXCAVATION, RIPRAP AND ROCK WEIR 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 9 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 9 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.

RESPONSIBLE TO ENSURE THAT THE STREAM FLOW DOES NOT GO

NOTES:
1. DESIGN DEWATERING FLOW FOR CONSTRUCTION IS 38 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.
