OLIVE CHURCH ROAD DAM REPLACEMENT PROJECT FOR DATE PROJECT NUMBER REVISIONS MAY 3RD 2023 GORDON COUNTY 116 PUBLIC SAFETY DR CALHOUN, GA 30701 SHEET TITLE SHEET NUMBER MT. OLIVE CHURCH RD. GORDON COUNTY, GA N GRADING & DRAINAGE PLAN EARTH EMBANKMENT CONSTRUCTION: (PER GEOTECHNICAL REPORT PREPARED BY GEOHYDRO ENGINEERS, DATED MARCH 24TH, 2004) · DAM EMBANKMENT: A TYPICAL MAXIMUM SLOPE GRADIENT FOR EARTHEN DAMS 3H:1V. STEEPER SLOPES MAY RESULT IN STABILITY PROBLEMS AND CAN BE DIFFICULT TO MAINTAIN. · DAM VEGETATION: VEGETATION ACCEPTABLE FOR A DAM SHOULD CONSIST OF GRASS COVER SUCH AS FESCUE OR BERMUDA. THE PRESENCE OF UNDERBRUSH AND TREES IMPEDE THE PROPER PERIODIC EVALUATION OF THE DAM FOR SEEPAGE, STRUCTURAL DAMAGE, OR ANIMAL BURROWS WHICH CAN LEAD TO THE DEGRADATION OF THE DAM. IN ADDITION, TREES SHOULD NOT BE ALLOWED TO GROW WITHIN THE EMBANKMENTS. SUCH PLANT GROWTH CAN LEAD TO STRUCTURAL STABILITY CONCERNS. · EROSION CONTROL: EROSION CONTROL MEASURES ALONG THE UPSTREAM EMBANKMENT AND EMBANKMENTS SHOULD CONSIST OF GRASS, RIP RAP, OR OTHER EROSION CONTROL MEASURES. PROPER EROSION CONTROL AT THE OUTLET STRUCTURE IN THE FORM OF A PLUNGE POOL LINED WITH RIP RAP WILL NEED TO BE INSTALLED TO ENSURE THE STRUCTURAL INTEGRITY OF THE OUTLET PIPE AND EMBANKMENT. · SPILLWAYS: THE PRINCIPAL SPILLWAY SHOULD BE DESIGNED TO MOVE WATER THROUGH THE DAM TO AN OUTLET AT THE BASE OF THE DAM DURING NORMAL FLOW CONDITIONS. THE OUTFLOW SHOULD BE RELEASED INTO A PLUNGE POOL. GRATES AND GUARDS SHOULD BE USED TO KEEP DEBRIS FROM ENTERING AND CLOGGING THE PIPES IN ADDITION TO KEEPING ANIMALS OUT. TYPICALLY, EMERGENCY SPILLWAYS ARE DESIGNED TO PASS FLOOD FLOW WITHIN A CONTROLLED AREA TO PREVENT OVERTOPPING. EARTH EMBANKMENT CONSTRUCTION -PAVEMENTS, TREES, UNDERBRUSH, TOPSOIL, ROOTS, AND OTHER DELETERIOUS MATERIALS SHOULD BE REMOVED FROM THE PROPOSED CONSTRICTION AREA. THE UPPER LAKE SHOULD BE DRAINED, AND THE STREAM CHANNEL SHOULD BE DIVERTED TO ALLOW DEMOLITION OF THE ROAD EMBANKMENT AND CONSTRUCTION OF THE NEW EMBANKMENT. TEMPORARY DEWATERING WILL BE NECESSARY TO MANAGE GROUNDWATER WITHIN THE NEW EMBANKMENT FOOTPRINT. DEWATERING REQUIREMENTS WILL BE DETERMINED BY SITE CONDITIONS AT THE TIME OF NEW CONSTRUCTION. GROUNDWATER LEVELS SHOULD BE MAINTAINED AT LEAST 3 FEET BELOW PREVAILING EXCAVATION LEVELS. WE EXPECT THAT DIRECT PUMPING FROM TEMPORARY TRENCHES AND SUMPS WILL SUFFICE TO MAINTAIN TEMPORARY CONTROL OF THE GROUNDWATER. THE COST AND TIME REQUIRED FOR TEMPORARY GROUNDWATER CONTROL MUST BE CONSIDERED FOR BUDGETING PURPOSES. THE CONTRACTOR MUST BE PREPARED TO IMPLEMENT TEMPORARY DEWATERING AS NECESSARY TO ALLOW WORK IN EXCAVATION. WE RECOMMEND THAT THE CONSTRUCTION DOCUMENTS INCLUDE A MINIMUM PERFORMANCE SPECIFICATION FOR DEWATERING. THIS SPECIFICATION SHOULD REQUIRE SPECIFIC RESULTS FROM DEWATERING RATHER THAN DICTATE A DEWATERING METHOD. A SAMPLE GUIDE SPECIFICATION IS INCLUDED IN THE APPENDIX AS EXHIBIT IN GENERAL, WE FEEL THAT EXHIBIT REPRESENTS THE MINIMUM SPECIFICATION FOR A PROJECT OF THIS SCOPE. -BASED ON OUR EXPERIENCE, WE EXPECT AREAS OF SOFT SOILS WITHIN THE FOUNDATION AREAS FOR THE NEW EMBANKMENT. AFTER EXPOSURE OF THE FOUNDATION FOR THE NEW EMBANKMENT, THE FOUNDATION AREA SHOULD BE OBSERVED GEO- HYDRO. ANY EXCESSIVELY SOFT FOUNDATION MATERIAL SHOULD BE REMOVED AND REPLACED WITH SUITABLE, WELL COMPACTED STRUCTURAL FILL. -TO REDUCE SEEPAGE ALONG THE PRINCIPAL SPILLWAY PIPE, THE TRENCH FOR THE PIPE MUST BE BACKFILLED WITH CONCRETE UP TO THE SPRINGLINE. THE TRENCH EXCAVATION SHOULD BE THOROUGHLY CLEANED TO AVOID LOOSE MATERIALS WHICH COULD CREATE VOIDS OR CONDUITS BETWEEN THE CONCRETE AND THE TRENCH SIDES AND BOTTOM. -ABOVE THE SPRINGLINE, THE BACKFILL SOILS OVER THE PRINCIPAL SPILLWAY PIPE SHOULD BE CAREFULLY COMPACTED WITH HAND OPERATED EQUIPMENT UNTIL ENOUGH COVER HAS BEEN PLACED TO ALLOW THE OPERATION OF CONVENTIONAL SELF-PROPELLED COMPACTION EQUIPMENT. -IN ADDITION TO PROPER BACKFILLING ALONG THE PRINCIPAL SPILLWAY TRENCH, WE RECOMMEND THAT ANTI SEEP COLLARS BE INSTALLED. ANTI SEEP COLLARS SHOULD FURTHER REDUCE SEEPAGE ALONG THE PRINCIPAL SPILLWAY PIPE TRENCH. CONSTRUCTION OF ANTI SEEP COLLARS AND BACKFILLING AROUND THE COLLARS IS OFTEN DIFFICULT AND LABOR INTENSIVE. SPECIAL ATTENTION SHOULD BE PAID TO PROPER BACKFILLING TO AVOID AREAS OF LOOSE SOIL WHICH MAY CREATE VOIDS OR CONDUITS. HAND OPERATED COMPACTION EQUIPMENT WILL BE REQUIRED FOR BACKFILLING AROUND ANTI SEEP COLLARS. -TYPICAL EARTHEN EMBANKMENT DAMS ARE CONSTRUCTED OF MATERIALS WITH HYDRAULIC CONDUCTIVITY ON THE ORDER OF 1 X 10^-6 CM/SEC OR LOWER. SOME DESIGNS MAY INCLUDE A CORE OF LESSER HYDRAULIC CONDUCTIVITY MATERIALS PROTECTED BY CONVENTIONAL FILL MATERIALS. ALTERNATELY, THE EMBANKMENT MAY BE CONSTRUCTED AS A HOMOGENEOUS MASS WITH SOILS THROUGHOUT THE EMBANKMENT HAVING THE SAME HYDRAULIC CONDUCTIVITY. -MATERIALS SELECTED FOR USE AS STRUCTURAL FILL SHOULD BE FREE OF ORGANIC MATTER AND OTHER DELETERIOUS MATERIALS. THE MATERIAL SHOULD NOT CONTAIN ROCKS HAVING DIAMETER OVER 3 INCHES. THE MOISTURE CONTENT OF SUITABLE BURROW SOILS SHOULD BE WET OPTIMUM FOR CONSTRUCTION OF THE EARTH EMBANKMENT. TYPICALLY, MOISTURE CONTENTS UP TO ABOUT 4 PERCENT POINTS ABOVE OPTIMUM WILL BE ADEQUATE FOR THIS APPLICATION. TIGHTER MOISTURE LIMITS MAY BE NECESSARY WITH CERTAIN SOILS. USE OF SOILS HAVING MOISTURE CONTENT DRY OF OPTIMUM IS NOT ACCEPTABLE. -SUITABLE FILL MATERIAL SHOULD BE PLACED IN THIN LIFTS (LIFT THICKNESS DEPENDS ON TYPE OF COMPACTION EQUIPMENT, BUT IN GENERAL, LIFTS OF 8 INCHES LOOSE MEASUREMENT ARE RECOMMENDED.) THE SOILS SHOULD BE COMPACTED BY HEAVY COMPACTION EQUIPMENT SUCH AS A CATERPILLAR 815 SHEEPSFOOT ROLLER. FILL MATERIALS SHOULD BE PLACED OVER AS LARGE AS AN AREA OF THE EMBANKMENT FOOTPRINT AS POSSIBLE AT ANY GIVEN TIME TO MINIMIZE VERTICALLY ORIENTED INTERFACES BETWEEN ZONES OF FILL PLACED AT DIFFERENT TIMES. AS THE EMBANKMENT IS CONSTRUCTED, FILL ON THE FACE OF THE SLOPES SHOULD BE COMPACTED BY OPERATING TRACK MOUNTED EQUIPMENT UP AND DOWN THE SLOPES. -AS THE EARTH EMBANKMENT IS CONSTRUCTED, NO PREVIOUS FILL LIFT SHOULD BE LEFT IN A SMOOTH CONDITION. SHOULD A SMOOTH CONDITION DEVELOP, SUCH AS RESULTS FROM THE RUBBER TIRED ROLLING, IT WILL BE NECESSARY TO SCARIFY THE EMBANKMENT SURFACE TO ASSURE ADEQUATE BONDING WITH THE NEXT LIFT OF FILL MATERIAL. ADDITIONALLY, DURING BREAKS IN CONSTRUCTION ACTIVITIES, SHOULD EXPOSED SUBGRADE BECOME OVERLY WET OR DRY, IT WILL BE NECESSARY TO BLADE THESE SOILS OFF, OR SCARIFY AND RECOMPACT THESE SOILS IN PLACE PRIOR TO PLACEMENT OF SUBSEQUENT FILL LAYERS. FILL PLACED ON THE FACE OF THE EXISTING SLOPES SHOULD BE ADEQUATELY BENCHED INTO THE EXISTING SLOPE TO PROVIDE A HORIZONTAL SURFACE FOR COMPACTION AND MINIMIZE THE CHANGES OF SLIPPAGE AT THE CUT/FILL INTERFACE. -WE RECOMMEND THAT STRUCTURAL FILL BE COMPACTED TO AT LEAST 95 PERCENT OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY (ASTM D-698.) GEO- HYDRO SHOULD OBSERVE PLACEMENT OF STRUCTURAL FILL ON A FULL-TIME BASIS AND PERFORM DENSITY TEST. NOTE: 98% STANDARD PROCTOR COMPACTION IS REQUIRED IN ALL AREAS OF FILL. GEOTECHNICAL ENGINEER TO OBSERVE PLACEMENT OF FILL DURING CONSTRUCTION. LAKE POND PIPE TRENCH TO BE FILLED WILL CONCRETE UP TO THE SPRINGLINE. NO TREE GROWTH ON DAMS. DAM IS TO MAINTAIN A GOOD STAND OF GRASS, AND TO BE MAINTAINED BY GORDON COUNTY TO PREVENT BRUSH AND TREE GROWTH. ---PAGE BREAK--- F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F BP: 0+00.00 PC: 0+75.74 PT: 1+07.66 PC: 1+47.53 PT: 2+49.11 PC: 3+96.77 PT: 4+07.14 PC: 5+49.42 PT: 6+10.16 40' 18.3' F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F F FLOATING TURBIDITY CURTAIN FLOATING TURBIDITY CURTAIN FLOATING TURBIDITY CURTAIN FLOATING TURBIDITY CURTAIN 25' 25' ANCHOR ON LAND ANCHOR ON LAND ANCHOR ON LAND ANCHOR ON LAND 25' 25' Ss Su Ds1 Ds2 Du Ds3 Ss Su Ds1 Ds2 Du Ds3 Ss Su Ds1 Ds2 Du Ds3 Ss Su Ds1 Ds2 Du Ds3 Ss Su Ds1 Ds2 Du Ds3 Ss Su Ds1 Ds2 Du Ds3 Sd1-S Sd1-S Sd1-S Sd1-S Sd1-S DOUBLE ROW DOUBLE ROW DOUBLE ROW DOUBLE ROW DOUBLE ROW LIMITS OF DISTURBANCE LIMITS OF DISTURBANCE LIMITS OF DISTURBANCE LIMITS OF DISTURBANCE Ds1 Ds2 Ds1 Ds2 Ds1 Ds2 Ds1 Ds2 Ds1 Ds2 Ds1 Ds2 St CONCRETE WASHOUT SAMPLING LOCATION SAMPLING LOCATION UPSTREAM Co 0+00 1+00 2+00 3+00 4+00 5+00 6+00 748 750 752 750 750 754 754 754 754 754 754 TOE OF PROPOSED SLOPE LIMITS OF FILL TOE OF PROPOSED SLOPE LIMITS OF FILL CONTRACTOR TO USE A SIPHON OR PUMP TO DRAW DOWN THE UPPER LAKE WATER LEVEL TO BELOW THE PROPOSED FILL LINE CONTRACTOR TO CONSTRUCT A COFFERDAM FOR FILL PLACEMENT IN THE LOWER LAKE.

THE DAM IS IN NEED OF REPAIR DUE TO INADEQUATE SIDE SLOPES. THE ROAD DAM AND THE EXISTING OUTLET PIPES WILL BE REMOVED. THE EXISTING LAKE WILL NEED TO BE DRAINED IN ORDER TO PLACE FILL FOR THE PROPOSED DAM RESTORATION. FILL WILL BE PLACED WITHIN THE EXISTING LAKE OPEN WATERS, THEREFORE A CORP OF ENGINEERS PERMIT WILL BE REQUIRED ALONG WITH AN EPD BUFFER VARIANCE. CURRENTLY THE ROAD DAM CONSIST OF TREES AND SHRUBS WITH STEEP SIDE SLOPES. THE PROPOSED DAM WILL CONSIST OF A GOOD STAND OF GRASS WITH 2:1 SIDE SLOPES. A NEW LAKE OUTLET WILL BE INSTALLED. THE POLLUTANT SOURCES WILL BE SILT, SEDIMENT, AND OTHER SUSPENDED SOLIDS DURING THE CONSTRUCTION PROCESS. THE PROJECT'S INITIAL RECEIVING WATER IS AN UN-NAMED TRIBUTARY TO PINE LOG CREEK A WARM WATER STREAM. IT IS NOT AN IMPAIRED STREAM SEGMENT. THERE ARE SENSITIVE AREAS ON SITE, INCLUDING LAKES, RESIDENTIAL AREAS, WETLANDS, ETC. A CORP OF ENGINEERS AND EPD BUFFER VARIANCE ARE REQUIRED PRIOR TO CONSTRUCTION. THE DESIGN PROFESSIONAL WHO PREPARED THE ES&PC PLAN IS TO INSPECT THE INSTALLATION OF INITIAL SEDIMENT STORAGE REQUIREMENTS, PERIMETER CONTROL BMPs, AND SEDIMENT BASINS IN ACCORDANCE WITH PART IV.A.5.
