PROJECT DESCRIPTION

TITLE: EMBANKMENT ROCK RECONSTRUCTION

REFERENCE: 113

LOCATION: BOAT BASIN ROAD

TAX LOT(S): 1400, 1300, 401

NATURAL FEATURES

EXISTING NATURAL RESOURCES OR NATURAL HAZARDS ON THE SUBJECT

PROPERTY, INCLUDING WETLANDS, STREAMS, RIPARIAN AREAS, FLOOD PLAINS, OR

FLOODWAYS TO BE DETERMINED BY ENGINEER

EXISTING TREE CANOPY

THERE IS LOW STORY SHRUBBERY/VEGETATION ON THE SUBJECT PROPERTY

CULTURAL RESOURCES

ON THE SITE OR ON ADJACENT PARCELS TO BE DETERMINED BY ENGINEER.

PUBLIC SERVICES

PUBLIC UTILITY SERVICES, INCLUDING WATER, SEWER, STORM DRAINAGE, POWER,

TELEPHONE, CABLE INTERNET, AND GAS ARE AVAILABLE TO THE SUBJECT

PROPERTY.

UTILITY STATEMENT

EXISTING UNDERGROUND UTILITIES ILLUSTRATED IN THESE PLANS ARE

APPROXIMATED BASED ON MAPS OBTAINED FROM CURRY COUNTY GIS ELEVATIONS

ESTIMATES, OR HAVE BEEN LOCATED BY A UTILITY LOCATE COMPANY. LAYOUT

INDICATED IS NOT TO BE RELIED ON AS BEING EXACT OR COMPLETE. ALL LINES

WITHIN PROJECTED WORK ZONE SHALL BE FIELD VERIFIED AS REQUIRED PRIOR TO

CONSTRUCTION.

1. DEQ 1200-C PERMIT IS NOT REQUIRED.

2. UNLESS DIRECTED OTHERWISE, REMOVE CLEARED AND GRUBBED MATERIAL FROM

THE SITE AND DISPOSE AT AN APPROVED LOCATION.

3. PRIOR TO THE START OF CONSTRUCTION, VERIFY GRADES AT SAWCUT LOCATIONS

AND MATCHING OF EXISTING GRADE LOCATIONS.

4. MINIMIZE TRAFFIC ON SOIL AREAS DURING WET WEATHER. IF THE SITE SOILS ARE

EXPOSED DURING WET WEATHER, THE USE OF CRUSHED ROCK PLACED AS

ENGINEERED FILL IN THE BOTTOM OF THE EXCAVATIONS MAY BE NECESSARY TO

PROTECT THE SUBGRADE. TAKE ALL PRECAUTIONS TO LIMIT SURFACE

DISTURBANCE AND PROTECT THE SITE GRADING AREA FROM EROSION AND

RUNOFF. AVOID DISTURBANCE OF EXISTING SOIL STRUCTURE.

5. UNLESS OTHERWISE NOTED, THE SAMPLING AND TESTING OF MATERIALS FOR USE

ON THE JOBSITE SHALL BE AT THE EXPENSE OF THE CONTRACTOR. ALL TESTING OF

MATERIALS AND WORKMANSHIP SHALL BE PERFORMED BY A CERTIFIED

INDEPENDENT TESTER. RESULTS OF THE TESTS SHALL BE SENT DIRECTLY TO THE

PROJECT ENGINEER AS WELL AS THE CONTRACTOR, BY THE LABORATORY.

LOCATION AND FREQUENCY OF TESTS SHALL BE DESIGNATED BY THE GENERAL

CONTRACTOR.

6. ALL CUT AND FILL SLOPES SHALL BE MAXIMUM OF 1.5:1.

DESIGN SPECIFICS OF ROCK & CONSTRUCTION

THE ROCK USED FOR THIS PROJECT WILL BE SPECIFIED TO FOLLOW TEST REQUIREMENTS FOUND

WITHIN AASHTO 85 (APPARENT SPECIFIC GRAVITY, PERCENT ABSORPTION); ODOT TM 208A

(DEGRADATION); AND AASHTO T 104 (SOUNDNESS). ALL ROCK SPECIFIED IN THIS PROJECT MUST BE ANGULAR IN SHAPE, AND THE THICKNESS OF ANY SINGLE ROCK SHALL NOT BE LESS THAN ONE THIRD OF ITS LENGTH. ROUND ROCK WILL NOT BE ACCEPTED UNLESS AUTHORIZED BY EMC. THE

ROCK MUST MEET THE GRADATION REQUIREMENTS FOR THE CLASS SPECIFIED, BE FREE FROM

OVERBURDEN, SPOILED, SHALE AND ORGANIC MATERIAL. NON-DURABLE ROCK, SHALE OR ROCK

WITH SHALE SEAMS IS NOT ACCEPTABLE. CLASS 2000 RIP RAP IS BY DEFINITION COMPRISED OF ROCKS THAT ARE 20% BY WEIGHT OF 1400 POUNDS TO 2000 POUNDS, 30% BY WEIGHT OF 700 TO 1400 POUNDS, 40% BY WEIGHT 40 TO 700 POUNDS AND 0 TO 10% 0 TO 40 POUNDS. EITHER A FILTER BLANKET OF 16 INCH LAYER OF CLASS 50, OR SPECIFIED FILTER FABRIC WILL BE LAID BENEATH THE

ROCK.

A CLAMSHELL, ORANGE PEEL BUCKET, SKIP OR SIMILAR APPROVED DEVICE WILL BE USED WHICH WILL TRANSPORT THE RIPRAP MATERIAL TO ITS FINAL DESTINATION. THIS REVETMENT REPAIR IS FOR FLOW ASSUMED TO GENERALLY BE UNIFORM, STEADY AND SUBCRITICAL. HOWEVER, RAPIDLY

VARYING, UNSTEADY FLOW CONDITIONS OCCUR OCCASIONALLY, AND EXCESSIVE WAVE ACTION,

HYDRAULIC JUMPS AND EXTREME FLOW TURBULENCE CAN OCCUR AT THIS LOCATION. THESE

CONDITIONS ARE AMONG THE REASONS FOR THE EXTENT OF PROTECTION PROPOSED. THE

LONGITUDINAL EXTENT OF THIS REPAIR SHOULD BE CONTINUOUS FOR A DISTANCE GREATER THAN

THE LENGTH THAT IS IMPACTED. THE VERTICAL EXTENT OF PROTECTION REQUIRED FOR THIS

REVETMENT INCLUDES DESIGN HEIGHT AND FOUNDATION OR TOE DEPTH. THE DESIGN HEIGHT OF THE RIP RAP INSTALLATION IS TO BE EQUAL TO THE DESIGN HIGH WATER ELEVATION (KING TIDE

PLUS STORM SURGE) WITH ADEQUATE FREEBOARD TO ACCOMMODATE WAVE ACTION, SUPER

ELEVATION FROM THE CHANNEL BEND, HYDRAULIC JUMP, AND FLOW IRREGULARITIES, PLUS

ERRATIC PHENOMENA SUCH AS UNFORESEEN EMBANKMENT SETTLEMENT, ACCUMULATION OF

TRASH AND DEBRIS FROM THE RIVER.

SCOUR DEPTH IS ESTIMATED AT ABOUT 4 FEET FROM THE LOWEST ELEVATION IN THE

CROSS-SECTION OF THE BASIN AT THIS POINT, UTILIZING THE CONSERVATIVE ASSUMPTION OF A MEDIAN DIAMETER OF BED MATERIAL TO BE ABOUT 0.15 M. RIPRAP THICKNESS FOR CLASS 2000 IS

SPECIFIED TO BE AT LEAST A 4 FOOT LAYER.

THE FILTER BENEATH THE RIPRAP AND OVERLYING THE STRUCTURAL FILL IS TO PREVENT THE

MIGRATION OF FINE SOIL PARTICLES THROUGH STRUCTURAL VOIDS AND TO DISTRIBUTE THE

WEIGHT OF THE ARMORING UNITS (RIPRAP) TO PROVIDE MORE UNIFORM SETTLEMENT, AND ALSO

PERMITS RELIEF OF HYDROSTATIC PRESSURES WITHIN THE SOILS.

FOR THE AREAS ABOVE THE WATERLINE AT ANY GIVEN TIME THE FABRIC OR GEOTEXTILE ALSO PREVENTS SURFACE WATER FROM CAUSING EROSION BENEATH THE RIP RAP. IN ADDITION TO TOE CONSIDERATIONS WITH RESPECT TO SCOUR THE FLANKS OF THIS REVETMENT ARE DESIGNED FOR

UPSTREAM AND DOWNSTREAM CONDITIONS

GENERAL CONSTRUCTION, EROSION & CONTROL NOTES

FINAL BANK SLOPE WILL BE NOT GREATER THAN 1V:1.5H. BANK PREPARATION WILL CONSIST OF CLEARING DEBRIS AND MINOR GRADING. RIPRAP PLACEMENT WILL BE BY MACHINE PLACING AND

HAND PLACING. HAND PLACING WILL BE PERFORMED AS SPECIFIED BY EMC ON STEEPER SIDE

SLOPES.

RE-HANDLING OR DRAGGING TO SMOOTH REVETMENT SERVICES TEND TO RESULT IN SEGREGATION

AND BREAKAGE OF STONE AND ARE TO BE AVOIDED. STONE WILL NOT BE DROPPED FROM AN

EXCESSIVE HEIGHT.

ACTIONS THAT WILL REQUIRE THE USE OF MATERIALS THAT ARE HAZARDOUS OR TOXIC TO AQUATIC LIFE (SUCH AS MOTOR FUEL, OIL, OR DRILLING FLUID), ARE INCLUDED WITHIN THE POLLUTION AND EROSION CONTROL PLAN SECTIONS OF THIS NARRATIVE, TO BE MANAGED BY EMC AND ENFORCED BY THE PORT OF BROOKINGS-HARBOR. THE PLAN INCLUDES PRACTICES TO MINIMIZE EROSION AND

SEDIMENTATION ASSOCIATED WITH ALL ASPECTS OF THE PROJECT (E.G., STAGING AREAS,

STOCKPILES, GRADING); TO PREVENT DEBRIS FROM DROPPING OR OTHERWISE ENTERING ANY

STREAM OR WATERBODY; AND TO PREVENT AND CONTROL HAZARDOUS MATERIAL SPILLS.

EROSION CONTROLS WILL BE MONITORED AND MAINTAINED DAILY DURING THE RAINY SEASON AND

WEEKLY DURING THE DRY SEASON AS NECESSARY TO ENSURE CONTROLS ARE PROPERLY

FUNCTIONING. IF MONITORING SHOWS THAT THE EROSION CONTROLS ARE INEFFECTIVE AT

PREVENTING VISIBLE SEDIMENT DISCHARGE, THE PROJECT WILL STOP TO EVALUATE EROSION

CONTROL MEASURES. REPAIRS, REPLACEMENTS OR THE INSTALLATION OF ADDITIONAL EROSION

CONTROL MEASURES WILL BE COMPLETED BEFORE THE PROJECT RESUMES.

IF APPLICABLE, MAINTENANCE WILL INCLUDE REMOVAL OF SEDIMENT AND DEBRIS FROM EROSION CONTROLS LIKE SILT FENCES OR HAY BALES AND TURBIDITY CURTAINS ONCE IT HAS REACHED ONE-THIRD OF THE EXPOSED HEIGHT OF THE CONTROL. WHENEVER PRACTICAL, NATIVE MATERIALS ARE TO BE LEFT WHERE THEY ARE FOUND AND IN AREAS TO BE CLEARED, VEGETATION IS TO BE

CLIPPED AT GROUND LEVEL TO RETAIN ROOT MASS AND ENCOURAGE REESTABLISHMENT OF

NATIVE VEGETATION.

HEAVY EQUIPMENT WILL BE SELECTED AND OPERATED AS NECESSARY TO MINIMIZE ADVERSE

EFFECTS ON THE ENVIRONMENT (E.G., MINIMALLY-SIZED, LOW PRESSURE TIRES, MINIMAL HARD

TURN PATHS FOR TRACKED VEHICLES, TEMPORARY MATS OR PLATES WITHIN WET AREAS OR

SENSITIVE SOILS); AND ALL VEHICLES AND OTHER HEAVY EQUIPMENT WILL BE USED AS FOLLOWS:

1) STORED, FUELED AND MAINTAINED IN A VEHICLE STAGING AREA PLACED 150 FEET OR MORE

FROM ANY WATERBODY, OR IN AN ISOLATED HARD ZONE SUCH AS A PAVED PARKING LOT, OR

LINED SURFACE;

2) INSPECTED DAILY FOR FLUID LEAKS BEFORE LEAVING THE VEHICLE STAGING AREA FOR

OPERATION WITHIN 50 FEET OF ANY WATERBODY;

3) STEAM-CLEANED BEFORE OPERATION BELOW ORDINARY HIGH WATER, AND AS OFTEN AS

NECESSARY DURING OPERATION TO REMAIN FREE OF ALL EXTERNAL OIL, GREASE, MUD, SEEDS, ORGANISMS AND OTHER VISIBLE CONTAMINANTS AND

4) GENERATORS, CRANES AND ANY OTHER STATIONARY EQUIPMENT OPERATED WITHIN 150 FEET

OF ANY WATERBODY WILL BE MAINTAINED AND PROTECTED AS NECESSARY TO PREVENT LEAKS

AND SPILLS FROM ENTERING THE WATER.
