3.4 SHEET GRADING DETAIL V1SITE GRADING
1. ALL GRADING SHALL BE IN ACCORDANCE WITH THE APPROVED GRADING PLAN
2. A CONSTRUCTION PROJECT SCHEDULE SHALL BE SUBMITTED TO THE ENGINEER FOR APPROVAL AND SHALL BE PERIODICALLY UPDATED IF CONDITIONS OR
SCHEDULES CHANGE. CONSTRUCTION SHALL BE SCHEDULED TO MINIMIZE SOIL DISTURBANCE. ALL DISTURBED SURFACES SHALL BE STABILIZED IN A
TEMPORARY OR PERMANENT MANNER AS APPROPRIATE DURING CONSTRUCTION TO PREVENT SOIL EROSION.
3. THE CONTRACTOR SHALL REVIEW AND FOLLOW ALL RECOMMENDATIONS PROVIDED IN THE GEOTECHNICAL ENGINEERING REPORT PREPARED BY SITE
CONSULTING, LLC DATED 06/05/2014.
4. ORGANIC SOILS SHALL BE REMOVED AS RECOMMENDED IN THE GEOTECHNICAL REPORT AND WASTED OR STOCKPILED FOR USE IN FINE GRADING.
5. PRIOR TO COMMENCING STRUCTURAL FILL, THE EXISTING SITE DEBRIS MUST BE REMOVED, THE NATIVE SOILS STRIPPED OF ALL ORGANIC MATERIAL,
STOCKPILES OF SUITABLE MATERIAL SHALL BE SEGREGATED FROM UNSUITABLE MATERIALS. ALL WASTE AND HIGHLY ORGANIC OR OTHERWISE CONTAMINATED
SOILS SHALL BE REMOVED FROM THE SITE AND NOT STOCKPILED FOR ANY PERIOD OF TIME. WHERE PRACTICAL, STOCKPILES OF MATERIALS TO BE USED
AS STRUCTURAL FILL SHALL BE PLACED ON NATIVE, STRIPPED SOILS TO PREVENT CONTAMINATION.
6. EXACT REMOVAL DEPTHS OF ORGANIC MATERIALS SHALL BE DETERMINED DURING GRADING OPERATIONS BY A QUALIFIED GEOTECHNICAL REPRESENTATIVE
AND/OR THE PROJECT ENGINEER, AND SHALL BE BASED ON SUBGRADE SOIL TYPE, COMPOSITION, AND FIRMNESS OR SOIL STABILITY.
7. ALL MATERIAL USED FOR STRUCTURAL FILL SHALL MEET THE REQUIREMENTS FOR STRUCTURAL FILL AS DESCRIBED IN THE GEOLOGY AND GEOTECHNICAL
REPORT. STRUCTURAL FILL MUST BE USED WHERE FILL HEIGHT EXCEEDS ONE (1) VERTICAL FOOT OR WHERE RECOMMENDED BY REFERENCED GEOTECHNICAL
REPORT.
8. STRUCTURAL FILL SHALL BE PLACED IN ACCORDANCE WITH THE REQUIREMENTS OF THE GEOLOGY AND GEOTECHNICAL REPORT AND COMPACTION SHALL
BE SUPERVISED BY A QUALIFIED GEOTECHNICAL REPRESENTATIVE AND/OR THE PROJECT ENGINEER. MATERIAL SHALL BE PLACED IN 8" LIFTS UNLESS
OTHERWISE APPROVED BY THE GEOTECHNICAL ENGINEER.
9. ALL STRUCTURAL FILL SHALL BE COMPACTED TO A MINIMUM OF 95% OF MAXIMUM DRY DENSITY AS DETERMINED BY ASTM D 1557 FOR BUILDING LOTS
OR D 698 FOR ROAD AREAS. ONE IN —PLACE DENSITY TEST PER LIFT SHALL BE CONDUCTED FOR EVERY 5000 SQUARE FEET OF LIFT AREA FOR BUILDING
STRUCTURES (ONE PER LOT) OR FOR EVERY 100 LINEAR FEET OF LIFT AREA IN PARKING AND DRIVEWAY AREAS.
10. SHALLOW EXCAVATIONS THAT DO NOT EXCEED 4 FEET MAY BE CONSTRUCTED WITH SIDE SLOPES APPROACHING VERTICAL. BELOW THIS DEPTH, SLOPES
SHALL NOT EXCEED 1-1/2 FOOT VERTICAL TO 1 FOOT HORIZONTAL.
11. FINAL SITE GRADES (CUT OR FILL) SHALL NOT EXCEED 1 FOOT VERTICAL TO 2 FEET HORIZONTAL.
12. PRIOR TO PLACEMENT OF STRUCTURAL FILL, THE GROUND SHALL BE PREPARED IN ACCORDANCE WITH APPENDIX J, 'GRADING' OF THE INTERNATIONAL
BUILDING CODE. FIGURE J107.3 AND AS DIRECTED BY THE PROJECT ENGINEER AND/OR THE GEOTECHNICAL ENGINEER.
13. ALL FINAL GRADING SHALL EMPLOY SLOPE ROUNDING AT TOPS OF SLOPES AND AT CHANGES IN HORIZONTAL SLOPE ALIGNMENT TO FACILITATE
REVEGETATION AND PROVIDE AN ASTHETICALLY ACCEPTABLE APPEARANCE.
14. DURING ALL GRADING OPERATIONS AND UNTIL THE ESTABLISHMENT OF PERMANENT REVEGETATION, THE CONTRACTOR SHALL PROVIDE EROSION AND
SEDIMENT CONTROL MEASURES IN ACCORDANCE WITH THE APPROVED STORMWATER PREVENTION PLAN.

NOTES:
1. THE BUILDING ENVELOPES ARE BASED ON CITY OF MERIDIAN SETBACKS
APPROVED WITH THE JUMP CREEK SUBDIVISION DEVELOPMENT.
�-H/5 OR 2' MIN
KEY MUST BE PROVIDED PER IBC
J107.3 IF FILL HEIGHT EXCEEDS 5
VERTICAL FEET.
2. THE MINIMUM TOP OF STEM WALL ELEVATIONS ARE BASED ON A 6" REVEAL, A
6" DROP IN THE FIRST TEN FEET, AND THEN 2% TO THE LOWEST TOP BACK OF
CURB FOR THE LOT OR 1% TO THE TOP OF BACKYARD SWALE (WHICHEVER IS
GREATER). MIN TOP OF STEM WALL IS BASED ON IRC, SECTION R401.3.
3. FOUNDATIONS MAY BE STEPPED A MAXIMUM OF 2 FEET
4. REAR YARD SWALES SHOULD BE NO CLOSER THAN 10 FEET FROM THE
STRUCTURE.
5. THE HOMEBUILDER SHALL REVIEW & FOLLOW ALL RECOMMENDATIONS SET FORTH
FOR THE SUBDIVISION IN THE 'RECOMMENDATIONS FOR HOMEBUILDERS' REPORT BY
SITE CONSULTING, LLC, DATED NOVEMBER 2014.
6. EACH BUILDER SHALL CONTINUE BACKYARD SWALE.
7. EXCEPTIONS TO THIS GRADING PLAN MAY BE APPROVED BY THE CITY OF
MERIDIAN BUILDING OFFICIAL AT ISSUANCE OF BUILDING PERMIT BASED UPON
REVIEW OF AN ENGINEERED INDIVIDUAL LOT GRADING PLAN.
8. QUANTITIES ARE APPROXIMATE RAW VOLUMES WITHOUT ADJUSTMENT FOR
