GENERAL GRADING NOTES
1.CONTRACTOR SHALL REFER TO THE STORMWATER POLLUTION PREVENTION PLAN AND DETAILS FOR CONSTRUCTION SCHEDULING AND EROSION
CONTROL MEASURES TO BE INSTALLED PRIOR TO EARTHMOVING ACTIVITIES.
2.REFER TO THE INDIANA DEPARTMENT OF TRANSPORTATION (INDOT) STANDARD SPECIFICATIONS, LATEST EDITION, FOR BASIC MATERIALS AND
CONSTRUCTION METHODS. THE SECTIONS BELOW FOR VARIOUS ITEMS ARE TO CLARIFY THE INTENT OF THE REQUIREMENTS FOR THIS PROJECT.
PLEASE NOTE THAT OTHER SECTIONS OF THE INDOT STANDARD SPECIFICATIONS MAY ALSO BE APPLICABLE.
3.TOPSOIL SHALL BE STRIPPED FROM ALL AREAS TO RECEIVE PAVING AND FROM WITHIN THE LIMITS OF PROPOSED BUILDINGS AND STRUCTURES.
TOPSOIL SHALL BE STRIPPED TO THE DEPTH AS NOTED IN THE GEOTECHNICAL REPORT.
4.AFTER STRIPPING TOPSOIL, PROOFROLL AREAS TO BE FILLED WITH A MEDIUM WEIGHT ROLLER TO DETERMINE LOCATIONS OF ANY POCKETS OF
UNSUITABLE MATERIAL. RECOMMENDATIONS FOR DRYING, AMENDING AND/OR REMOVAL OF ANY UNSUITABLE MATERIAL WITHIN THE PROPOSED PAVED
AND/OR BUILDING AREAS WILL BE DETERMINED AT THE TIME OF CONSTRUCTION BY THE OWNER'S GEOTECHNICAL TESTING REPRESENTATIVE.
5.TOPSOIL SHALL BE PLACED IN MOUNDING AREAS, NONSTRUCTURAL FILL AND/OR PLANTING AREAS TO A MINIMUM DEPTH OF 6". EXCESS TOPSOIL SHALL
BE REMOVED FROM THE SITE.
6.WHEN PERFORMING GRADING OPERATIONS DURING PERIODS OF WET WEATHER, PROVIDE ADEQUATE DEWATERING, DRAINAGE AND GROUND WATER
MANAGEMENT TO CONTROL MOISTURE OF SOILS. REFER TO GEOTECHNICAL REPORT AND/OR CONSULT WITH OWNER'S GEOTECHNICAL TESTING
REPRESENTATIVE FOR RECOMMENDATIONS.
7.FILL MATERIAL SHALL CONSIST OF EARTH OBTAINED FROM CUT AREAS, BORROW PITS OR OTHER APPROVED SOURCES. EARTH SHALL BE FREE FROM
ORGANIC MATTER AND OTHER DELETERIOUS SUBSTANCES AND LARGE ROCKS. THE FILL MATERIAL SHALL BE PLACED IN LAYERS NOT TO EXCEED SIX
INCHES FOLLOWING COMPACTION, PROPER MOISTURE CONTENT OF FILL MATERIAL WILL BE SUCH TO ACHIEVE SPECIFIED COMPACTION DENSITY. ALL
FILL BENEATH PAVED AREAS, FLOOR SLABS AND FUTURE BUILDINGS SHALL BE COMPACTED TO AT LEAST 95% OF THE MAXIMUM DRY DENSITY PER ASTM
D-1557. FIELD COMPACTING TEST SHALL BE RUN ON EACH LIFT, IN FILL SECTIONS, AND THE REQUIRED COMPACTION ON EACH LIFT SHALL BE IN
ACCORDANCE WITH INDOT SECTION 211.
8.MAXIMUM LAWN SLOPE IS 3:1.
9.THE PLANS SHOW THE LOCATION OF ALL KNOWN UTILITIES LOCATED WITHIN THE LIMITS OF CONSTRUCTION ACCORDING TO INFORMATION PROVIDED BY
THE VARIOUS UTILITY COMPANIES, PREVIOUS CONSTRUCTION PLANS AND AS EVIDENCED BY OBSERVATION OF ABOVE GROUND CONDITIONS BY THE
SURVEYOR. THE ACCURACY OF THIS INFORMATION IS NOT GUARANTEED.
10.THE CONTRACTOR SHALL CONTACT ALL UTILITY COMPANIES TO LOCATE MAINS, CONDUITS, SERVICE LINES, ETC. WITHIN THE CONSTRUCTION LIMITS.
THE LOCATION AND PROTECTION OF UTILITY STRUCTURES, THEIR SUPPORT AND MAINTENANCE DURING CONSTRUCTION (IN COOPERATION WITH
APPLICABLE UTILITY COMPANY) IS THE EXPRESSED RESPONSIBILITY OF THE CONTRACTOR.
11.ALL SPOT ELEVATIONS ARE TO FINISHED GRADE.
12.COMPACTED "B" BORROW BACK FILL REQ'D. OVER ALL UTILITIES IN PAVED AREAS.
13.ALL GRADES AT BOUNDARY SHALL MEET EXISTING. CONTRACTOR SHALL ADJUST AND/OR CUT EXISTING PAVEMENT AS NECESSARY TO ASSURE A
SMOOTH FIT AND CONTINUOUS GRADE. BUTT JOINTS SHALL BE PROVIDED AT TRANSITIONAL AREAS BETWEEN PROPOSED AND EXISTING PAVEMENT.
14.ANY PART OF SANITARY OR STORM SEWER TRENCHES RUNNING UNDER OR WITHIN 5' OF PAVEMENT TO BE BACKFILLED WITH GRANULAR MATERIAL.
15.ALL CONSTRUCTION ON THIS SITE TO BE PERFORMED IN COMPLIANCE WITH O.S.H.A. STANDARDS FOR WORKER SAFETY.
16.THE CONTRACTOR SHALL CONFIRM ALL EARTHWORK QUANTITIES PRIOR TO THE START OF CONSTRUCTION. IF AN EXCESS OR SHORTAGE OF EARTH IS
ENCOUNTERED, THE CONTRACTOR SHALL CONFIRM WITH THE OWNER AND ENGINEER THE REQUIREMENTS FOR STOCKPILING, REMOVAL OR IMPORTING
OF EARTH.
17.PROVIDE POSITIVE DRAINAGE WITHOUT PONDING IN ALL AREAS AFTER INSTALLATION. CONTRACTOR TO TEST FOR AND CORRECT ANY PONDING
CONDITIONS. ANY AREAS THAT HOLD WATER MORE THAN 1/8" DEEP SHALL BE CUT OUT AND CORRECTED TO POSITIVE DRAINAGE AT NO COST TO THE
OWNER/ DEVELOPER OR ENGINEER.
18.ADA ACCESSIBLE PARKING SPACES, RAMPS, AND ROUTES SHALL BE IN ACCORDANCE WITH THE LATEST ADA STANDARDS FOR ACCESSIBLE DESIGN.
19.VERTICAL CURVES, WITH A MINIMUM LENGTH OF 50', SHALL BE USED WHERE POSSIBLE BETWEEN VERTICAL CHANGES IN DIRECTION (SLOPE) TO ALLOW
FOR POSITIVE DRAINAGE AND SMOOTH TRANSITIONS.
20.CONTRACTOR TO INSTALL CONCRETE CRADLES WHEN THE VERTICAL SEPARATION (AS MEASURED FROM THE EXTERIOR OF THE PIPES) BETWEEN
SANITARY SEWER FACILITIES, WATER MAIN, AND STORM SEWERS IS 18" OR LESS.
21.ALL DISTURBED AREA SHALL BE STABILIZED IN ACCORDANCE TO THE STORM WATER POLLUTION PREVENTION PLAN AND LANDSCAPE PLAN.
22.UTILITY RELOCATIONS REQUIRED BY THE PROJECT SHALL BE THE RESPONSIBILITY OF THE DEVELOPER. UTILITY LINE RELOCATIONS REQUIRED FOR
ROAD PROJECTS THAT RESULT IN A CONFLICT WITH PROPOSED DEVELOPMENT SHALL BE THE RESPONSIBILITY OF THE DEVELOPER TO RESOLVE WITH
THE UTILITY. EXISTING POLE LINES REQUIRED TO BE RELOCATED SHALL BE RELOCATED TO WITHIN ONE FOOT OF PROPOSED RIGHT-OF-WAY LINE.
23.DAMAGE TO THE EXISTING RIGHT-OF-WAY SHALL BE RESTORED / REPAIRED TO THE SATISFACTION OF THE CITY AT THE COMPLETION OF THE PROJECT.
THE CONTRACTOR IS ENCOURAGED TO INSPECT THE RIGHT-OF-WAY WITH THE CITY PRIOR TO THE START OF CONSTRUCTION TO DOCUMENT THE
EXISTING CONDITION OF THE RIGHT-OF-WAY.
24.ALL EXISTING SUMP PUMP DISCHARGE SHALL BE MODIFIED TO DAYLIGHT FROM THE BANK OF THE PROPOSED POND, BE IT LENGTHENED OR
SHORTENED.
25.ONSITE STORM SEWER SHALL BE PRIVATE.
26.DOWNSPOUTS ENCOUNTERED DURING CONSTRUCTION SHALL BE CONNECTED TO PROPOSED DRAINAGE SYSTEM AND ROUTED TO POND. POSITIVE
DRAINAGE SHALL BE MAINTAINED AT ALL POINTS IN ROOF DRAINAGE SYSTEM.
