THE STORMWATER POND AND DAM SHOWN ON THIS PLAN SATISFIES REQUIREMENTS OF THE NORTH CAROLINA STATE DAM SAFETY LAW 1967 (AS
AMENDED THROUGH 1995) AND THE RULES AND REGULATIONS AS PRESENTED IN THE NORTH CAROLINA ADMINISTRATIVE CODE TITLE 15A,
SUBCHAPTER 2K - DAM SAFETY. EVEN IN THE CASE WHERE THE DAM SHOWN ON THIS PLAN IS DETERMINED BY THE STATE TO BE EXEMPT FROM
THE ABOVE NOTED DAM SAFETY REQUIREMENTS, I, AS THE QUALIFIED DESIGN ENGINEER, STATE THAT THE POND AND DAM ARE DESIGNED TO BE
SAFE AND ADEQUATE FOR THE PROTECTION OF PUBLIC HEALTH, SAFETY, WELFARE AND DOWNSTREAM PROPERTY. I UNDERSTAND THAT THIS
STATEMENT AS THE DESIGN ENGINEER SHALL NOT RELIEVE THE OWNER OR OPERATOR OF THE POND AND DAM FROM THE LEGAL DUTIES,
OBLIGATIONS, AND LIABILITIES ARISING FROM SUCH OWNERSHIP OR OPERATION.
1. ALL FILL SOILS FOR BERM /DAM SECTION SHALL BE CLEAN, IMPERMEABLE MATERIAL AND COMPACTED TO AT LEAST 98% STANDARD
PROCTOR MAXIMUM DRY DENSITY, AT OPTIMUM MOISTURE CONTENT. NO BLASTED MATERIALS SHALL BE USED IN THE EMBANKMENT
CONSTRUCTION. SOILS SHALL NOT EXHIBIT SIGNIFICANT SHRINK /SWELL OR DISPERSIVE CHARACTERISTICS. ON -SITE GEOTECHNICAL
ENGINEER SHALL APPROVE THE SOILS FOR PLACEMENT WITHIN THE BERM /DAM SECTION. THE GEOTECHNICAL ENGINEER SHALL ALSO
SPECIFY THE METHODS TO BE USED FOR PLACEMENT OF FILL.
2. IN ALL FILL AREAS OF THE BERM /DAM, A SOILS COMPACTION TEST SHALL BE CONDUCTED EACH 2500 SQUARE FEET PER VERTICAL FOOT OF
FILL.
3. A KEY TRENCH IS TO BE PROVIDED IN ALL FILL AREAS. TRENCH TO EXTEND A MINIMUM OF FIVE FEET BELOW EXISTING GRADE. SOILS AND
COMPACTION FOR KEY TRENCH SHALL MEET ALL REQUIREMENT OF #1 ABOVE.
4. NO WOODY VEGETATION OF ANY TYPE MAY BE LOCATED WITHIN 7' OF THE TOE OF THE BERM /DAM SLOPE.
5. FILL PLACEMENT SHALL NOT EXCEED A MAXIMUM 8" LIFT. EACH LIFT SHALL BE CONTINUOUS FOR THE ENTIRE LENGTH OF EMBANKMENT.
BEFORE PLACEMENT OF FILL FOR THE BERM /DAM SECTION, ALL UNSUITABLE MATERIAL SHALL BE REMOVED AND THE SURFACE PROPERLY
PREPARED FOR FILL PLACEMENT.
6. AN ADDITIONAL FIVE PERCENT (5 %) OF THE DESIGN HEIGHT OF AN EARTHEN EMBANKMENT DAM SHALL BE ADDED TO THE TOP OF DAM
ELEVATION DURING FILL PLACEMENT TO NEGATE FUTURE SETTLEMENT.
7. TO HELP ENSURE THE STORMWATER BMP BERM /DAMS HAVE MET THE STATE DAM SAFETY REGULATIONS AND THAT THE BERMS /DAMS
HAVE BEEN DESIGNED WITH PUBLIC HEALTH, SAFETY, AND WELFARE IN MIND THE ENGINEER'S STATEMENT OF POND AND DAM SAFETY IS
REQUIRED FOR BERMS /DAMS PROPOSED TO BE CONSTRUCT FOR STORMWATER BMPS THAT TEMPORARILY OR PERMANENTLY STORE
WATER.
8. CONCRETE DAMS AND SPILLWAY STRUCTURES SHALL BE DESIGNED AND BUILT IN ACCORDANCE WITH THE AMERICAN CONCRETE
INSTITUTE'S (All LATEST GUIDELINES. PARTICULAR ATTENTION SHALL BE PAID TO DESIGN AND ANALYSIS, WATER TIGHTNESS, CONCRETE
QUALITY AND CONSTRUCTION PRACTICES. STRUCTURES SHALL BE DESIGNED AND CONSTRUCTED TO MAINTAIN WATER TIGHTNESS BY
CONTROLLING AND LIMITING CRACKING WITH THE PROPER JOINT DESIGN AND SPACING. DOCUMENTATION IS TO BE SUBMITTED WITH
POND CERTIFICATION.
9. IF BLASTING IS USED TO REMOVE ROCK FROM THE POOL AREA, THE BLASTED AREA SHOULD BE OVER EXCAVATED TO A SUFFICIENT DEPTH
BELOW FINISH GRADE AND BROUGHT BACK TO FINISH GRADE WITH IMPERVIOUS SOIL MATERIAL COMPACTED IN PLACE OR AN ALTERNATE
METHOD CAN BE SUBMITTED FOR APPROVAL. DOCUMENTATION IS TO BE SUBMITTED WITH POND CERTIFICATION.

PLAN TING NO TE:
1. CONTRACTOR TO ENSURE THAT ALL BASIN AREAS ARE IN COMPLIANCE WITH EROSION CONTROL PLAN.
SEE EROSION CONTROL PLANS AND DETAILS FOR STABILIZATION SPECIFICATIONS.
2. CONTRACTOR SHALL NOTIFY LANDSCAPE ARCHITECT BEFORE INSTALLATION OF PLANT MATERIAL
AND /OR APPLICATION OF SEED MIXTURES.
3. GRASSES SPECIFIED TO BE SEEDED, SHALL BE HYDRO - SEEDED AT THE RATES AND PERCENTAGES AS
SPECIFIED IN THE ABOVE CHART, CONTRACTOR SHALL SUBMIT FINAL SEED MIXTURE TO
LANDSCAPE ARCHITECT FOR APPROVAL.
4. ANY SUBSTITUTION OF PLANT SIZES, QUANTITIES AND /OR SEEDING MIXTURES MUST BE APPROVED BY
LANDSCAPE ARCHITECT.
5. IN AREAS NORMALLY COVERED BY WATER, PLANTS ARE TO BE INSTALLED BETWEEN APRIL 1 AND
AUGUST 31.
6. THE TOP SIX (6) TO EIGHT (8) INCHES AQUATIC SHELF SHALL BE TILLED AND THE SOIL MUST ADHERE AS
FOLLOWS TO ENSURE SUCCESSFUL ESTABLISHMENT OF VEGETATION.
6.1. THE SOIL MUST BE UNIFORM AND FREE OF STONES, STUMPS, ROOTS OR OTHER SIMILAR MATERIAL
GREATER THAN 2 INCHES IN DIAMETER
6.2. THE pH SHOULD BE BETWEEN 4.5 AND 7.0. IF THE pH FALLS OUTSIDE OF THIS RANGE, IT MA BE
MODIFIED WITH LIME TO INCREASE THE pH OR IRON SULFATE AND SULFUR TO LOWER THE pH. THE
LIME OR IRON SULFATE MUST BE MIXED UNIFORMLY INTO THE SOIL PRIOR TO USE.
7. BEFORE PLANTING ADD 6 INCHES OF CERTIFIED COMPOST AND TILL INTO THE TOP 5 INCHES OF SOIL FOR
ALL TREE AND SHRUB PLANTINGS.
8. THE SOIL SHALL BE KEPT MOIST FOR ALL SOD AND PLANTED AREAS UNTIL ALL PLANTINGS ARE

PLAN TING NO TE:
1. CONTRACTOR TO ENSURE THAT ALL BASIN AREAS ARE IN COMPLIANCE WITH EROSION CONTROL PLAN.
SEE EROSION CONTROL PLANS AND DETAILS FOR STABILIZATION SPECIFICATIONS.
2. CONTRACTOR SHALL NOTIFY LANDSCAPE ARCHITECT BEFORE INSTALLATION OF PLANT MATERIAL
AND /OR APPLICATION OF SEED MIXTURES.
3. GRASSES SPECIFIED TO BE SEEDED, SHALL BE HYDRO - SEEDED AT THE RATES AND PERCENTAGES AS
SPECIFIED IN THE ABOVE CHART, CONTRACTOR SHALL SUBMIT FINAL SEED MIXTURE TO
LANDSCAPE ARCHITECT FOR APPROVAL.
4. ANY SUBSTITUTION OF PLANT SIZES, QUANTITIES AND /OR SEEDING MIXTURES MUST BE APPROVED BY
LANDSCAPE ARCHITECT.
5. IN AREAS NORMALLY COVERED BY WATER, PLANTS ARE TO BE INSTALLED BETWEEN APRIL 1 AND
AUGUST 31.
6. THE TOP SIX (6) TO EIGHT (8) INCHES AQUATIC SHELF SHALL BE TILLED AND THE SOIL MUST ADHERE AS
FOLLOWS TO ENSURE SUCCESSFUL ESTABLISHMENT OF VEGETATION.
6.1. THE SOIL MUST BE UNIFORM AND FREE OF STONES, STUMPS, ROOTS OR OTHER SIMILAR MATERIAL
GREATER THAN 2 INCHES IN DIAMETER
6.2. THE pH SHOULD BE BETWEEN 4.5 AND 7.0. IF THE pH FALLS OUTSIDE OF THIS RANGE, IT MA BE
MODIFIED WITH LIME TO INCREASE THE pH OR IRON SULFATE AND SULFUR TO LOWER THE pH. THE
LIME OR IRON SULFATE MUST BE MIXED UNIFORMLY INTO THE SOIL PRIOR TO USE.
7. BEFORE PLANTING ADD 6 INCHES OF CERTIFIED COMPOST AND TILL INTO THE TOP 5 INCHES OF SOIL FOR
ALL TREE AND SHRUB PLANTINGS.
8. THE SOIL SHALL BE KEPT MOIST FOR ALL SOD AND PLANTED AREAS UNTIL ALL PLANTINGS ARE
ESTABLISHED. THIS SHALL BE FOR A MINIMUM PERIOD OF SIX (6) WEEKS FROM THE COMPLETION OF
INSTALLATION OF ALL BMP PLANTINGS.
9. ZONE A AND ZONE B INDIVIDUAL PLANT TYPES SHALL BE RANDOMLY GROUPED INTO IRREGULAR SIZED
AND SHAPED MONOCULTURES. THESE MONOCULTURES ARE NOT TO EXCEED 60 SQUARE FEET IN SIZE.
10. PLANTING HOLES OR SLITS OF HERBACEOUS SPECIES INSTALLED ABOVE NORMAL WATER LEVEL SHALL
BE DEEP ENOUGH TO ALLOW THE CROWN OF THE PLANT TO BE AT GRADE LEVEL, WHILE THE ROOTS
EXTEND VERTICALLY INTO THE SUBSTRATE WITHOUT KINKING.
11. ALL RIPARIAN BUFFER TREES AND SHRUBS SHALL RECEIVE MULCH AS SPECIFIED PER SHEET L2.00.
12. NETTING MAY BE REQUIRED FOR PROPER PLANT ESTABLISHMENT IF GEESE AND / OR DUCKS ARE
PRESENT.
