4. JUSTIFICATION FOR SPECIFIED PLANTS:
—ALL SPECIES EASILY OBTAINABLE
—PLANTS MAINTAIN LOW GROWTH HEIGHT, IDEAL FOR RESIDENTIAL SETTING
—PLANTS PRODUCE RELATIVELY FAST GROUND COVERAGE
—LOW VEGETATIVE MAINTANENCE
5. ALL SLOPES ABOVE TEMPORARY POOL ELEVATION, ON OUTSIDE OF CONTAINMENT BERMS, AND
SURROUNDING AREAS TO BE PLANTED WITH TURF GRASS. (CENTIPEDE GRASS IS RECOMMENDED
BY DWQ)
6. DEVELOPER MAY ADD ADDITIONAL PLANTING TO BASE PLANTINGS FOR AESTHETIC PURPOSES
SO LONG AS PLANTS ARE ON THE APPROVED LIST OF SPECIES SPECIFIED IN THE BMP MANUAL
FOR WETLANDS.
SOIL MEDIA NOTES:
1. THE SOILS USED FOR THE DESIGN AND CONSTRUCTION OF A WET DETENTION BASIN MUST
HAVE A LOW PERMEABILITY. IF THIS IS NOT THE CASE THEN A LINER (CLAY OR MANUFACTURED
MATERIALS) WILL BE REQUIRED TO MAINTAIN THE LEVEL OF WATER NECESSARY IN THE
PERMANENT POOL, SPECIFICATIONS AS PROVIDED BY LICENSED GEOTECHNICAL ENGINEER.
2. IF "IN SITU" SOILS ARE TO BE USED THEN A SOIL ANALYSIS WILL NEED TO BE CONDUCTED
BY A LICENSED GEOTECHNICAL ENGINEER TO VERIFY THAT THE ONSITE SOIL IS ADEQUATE TO
ENSURE HEALTHY PLANT GROWTH AND PROPER INFILTRATION THROUGH THE SOIL. THE FOLLOWING
ITEMS SHOULD BE CHECK AND INCLUDED IN A SOIL ANALYSIS:
—SOIL pH
—SOIL TEXTURE
—SOILT TEST NCDA & CS
—CONTENT
—HYDRAULIC CONDUCTIVITY & INFILTRATION RATE (HIGHLY RECOMMENDED)
3, ANY SOILS THAT ARE USED IN THE CONSTRUCTION OF THE BMP MUST MEET THE FOLLOWING
REQUIREMENTS:
—MIX MUST BE UNIFORM AND FREE OF MATERIAL GREATER THEN 2" (STONES, STUMPS, ROOTS,
ETC.)
TEXTURE SHOULD BE LOAMY SAND, WITH NO MORE THEN 10% CLAY
—MIN. ORGANIC CONTENT OF 10% BY DRY WEIGHT (WOODY SPECIES) AND 5% (TURF AREAS)

GENERAL NOTES ® WET PON
1. THE INSIDE AND OUTSIDE OF THE WET DETENTION BASIN BERMS SHALL BE A MAX. 3:1 SLOPE AND
STABILIZED WITH PERMANENT APPROVED SEEDING. THE INSIDE OF THE FOREBAY BELOW PERMANENT
POOL DEPTH SHALL BE A MAX. 2:1 SLOPE.
2. RIPRAP APRONS SHALL BE CONSTRUCTED AT ALL STORM DRAIN INLET LOCATIONS PER APRON SIZING
CHART. APRONS SHALL EXTEND DOWN SLOPE OF BERM FROM PIPE OUTLET TO FOREBAY BOTTOM.
RIPRAP SHALL BE INSTALLED AT OUTLET OF POND DISCHARGE PIPE PER APRON SIZING CHART.
3. TOP OF FOREBAY BERM SHALL BE CONSTRUCTED TO ELEVATION OF 3' ABOVE BOTTOM OF POND AND BE
A MINIMUM 4' IN WIDTH.
4. LOW FLOW ORIFICE SHALL BE CONSTRUCTED OF PVC WITH 90 DEGREE ELBOW THAT EXTENDS TO A
DEPTH OF 12" BELOW THE PERMANENT POOL ELEVATION. ANY ADDITIONAL ORIFICES SHALL UTILIZE
SOME FORM OF TRASH GUARD.
5. INCLUDE ADDITIONAL ORIFICES IN THE OUTLET STRUCTURE PER THE DETAILS TO RELEASE FLOWS FROM
LARGER STORM EVENTS.
6. CONSTRUCT OUTLET STRUCTURE ON CONCRETE BALLAST PAD PER DESIGN SPECIFICATIONS. IF
BALLAST PAD IS NOT REQUIRED, ADD 12" MIN. STONE BEDDING.
7. EMERGENCY SPILLWAY SHALL BE CONSTRUCTED OF CLASS 1 RIPRAP. GEOTEXTILE FABRIC SHALL BE
PLACED UNDER STONE. RIPRAP SHALL EXTEND DOWN THE OUTSIDE OF THE BERM TO NATURAL GRADE.
8. BOTTOM OF BASIN TO BE GRADED TO ALLOW MIN. 0.50% SLOPE TOWARD OUTLET STRUCTURE.
9. DUE TO THE DIFFERENCE IN THE DISCHARGE PIPE INVERT VERSUS THE BOTTOM OF POND ELEVATION,
THE OUTLET STRUCTURE IS TO BE FILLED WITH CONCRETE TO AN ELEVATION EQUAL WITH THE
PERMANENT POOL.
10. THE WET POND MUST BE CONSTRUCTED OF LOW PERMEABILITY SOILS TO MAINTAIN THE PERMANENT
POOL ELEVATION. THE USE OF A CLAY LINER, GEOMEMBRANE OR GEOSYNTHETIC CLAY LINER WILL BE
REQUIRED SHOULD THE NATIVE SOILS (IN-SITU MATERIALS) DEMONSTRATE THE INABILITY TO MEET THE
REQUIRED LINER PARAMETERS -NATIVE SOILS AS TESTED BY A LICENSED GEOTECHNICAL ENGINEER.
ALTERNATIVE LINERS SHALL BE APPROVED ON A CASE-BY-CASE. LINER SHALL BE CONSTRUCTED OR
COMPACTED SUCH THAT THE INFILTRATION RATE IS NO MORE THAN 0.01 IN/HR
11. IF "IN-SITU" SOILS ARE TO BE USED, THEN A SOIL ANALYSIS SHALL BE CONDUCTED BY A LICENSED
GEOTECHNICAL ENGINEER TO VERIFY THAT THE ONSITE SOILS (RESIDUAL AND FILL) CONTAIN LOW
PERMEABILITY PROPERTIES SUFFICIENT TO RETAIN WATER WITHIN THE STRUCTURE. IT IS HIGHLY
RECOMMENDED THAT THE IN-SITU SOILS BE TESTED FOR HYDRAULIC CONDUCTIVITY & INFILTRATION
RATE.
12. ANY SOILS THAT ARE USED IN THE CONSTRUCTION OF THE BMP MUST MEET THE FOLLOWING
REQUIREMENTS: -MIX MUST BE UNIFORM AND FREE OF MATERIAL GREATER THAN 2" (STONES. STUMPS,
ROOTS, ETC.) -TEXTURE SHOULD BE LOAMY SAND, WITH NO MORE THAN 10% CLAY (EXCEPT LINER WHEN
REQUIRED) -MINIMUM ORGANIC CONTENT OF 10% BY DRY WEIGHT (WOODY SPECIES) AND 5% (TURF

4. POND SHALL BE MAINTAINED AS SPECIFIED AND MAINTENANCE IS THE RESPONSIBILITY OF THE
OWNER.
5. THE PROPERTY OWNER AND/OR HOA WILL BE RESPONSIBLE FOR THE ANNUAL INSPECTION OF
STORMWATER BMP'S.
6. THE GRASS SIDE SLOPES SHALL BE MOWED MONTHLY, OR AS NEEDED.
7. TREES AND INVASIVE SPECIES SHALL BE REMOVED FROM WITHIN THE POND AND ON THE
EMBANKMENTS ON A SEMI-ANNUAL BASIS.
8. TRASH SHALL BE REMOVED FROM THE INSIDE OF, AND AROUND THE POND OUTLET STRUCTURE AND
THE STRUCTURE SHALL BE EXAMINED FOR DAMAGES ANNUALLY.
9. THE OUTLET STRUCTURE ORIFICES ARE TO BE CLEANED AND UNCLOGGED MONTHLY, OR
IMMEDIATELY FOLLOWING LARGER STORM EVENTS.
10. THE OUTLET PIPE IS TO BE INSPECTED, CLEANED, AND REPAIRED AS NEEDED ON AN ANNUAL BASIS.
11. MONITOR THE ACCUMULATION OF SEDIMENTATION ANNUALLY. SEDIMENT IS TO BE REMOVED FROM
THE PERMANENT POOL WHEN THE VOLUME HAS BEEN REDUCED BY 25%. SIMILARLY, SEDIMENT IS TO
BE REMOVED FROM THE FOREBAY WHEN THE VOLUME HAS BEEN REDUCED BY 50%.
12. THE POND BOTTOM SHALL BE MAINTAINED TO PROVIDE PROPER DRAINAGE TOWARDS OUTLET
STRUCTURE. (0.5% MIN BOTTOM SLOPE).
13. ENERGY DISSIPATORS ARE TO BE INSPECTED, CLEANED, AND REPAIRED AS NEEDED.
14. REPAIRS TO THE POND BERMS, SIDE SLOPES, OR ANY ERODED AREAS SHALL BE ADDRESSED
ANNUALLY OR AS NEEDED.
15. MANAGEMENT OF ALL VEGETATION SHOULD BE MONITORED ON AN ANNUAL BASIS TO ENSURE
PROPER PLANT LIFE IS MAINTAINED AT ALL TIMES.
16. CITY OF STATESVILLE MUST BE NOTIFIED IN WRITING OF ANY CHANGES IN MAINTENANCE

FOR WETLANDS.
SOIL MEDIA NOTES:
1. THE SOILS USED FOR THE DESIGN AND CONSTRUCTION OF A WET DETENTION BASIN MUST
HAVE A LOW PERMEABILITY. IF THIS IS NOT THE CASE THEN A LINER (CLAY OR MANUFACTURED
MATERIALS) WILL BE REQUIRED TO MAINTAIN THE LEVEL OF WATER NECESSARY IN THE
PERMANENT POOL, SPECIFICATIONS AS PROVIDED BY LICENSED GEOTECHNICAL ENGINEER,
2. IF "IN SITU" SOILS ARE TO BE USED THEN A SOIL ANALYSIS WILL NEED TO BE CONDUCTED
BY A LICENSED GEOTECHNICAL ENGINEER TO VERIFY THAT THE ONSITE SOIL IS ADEQUATE TO
ENSURE HEALTHY PLANT GROWTH AND PROPER INFILTRATION THROUGH THE SOIL. THE FOLLOWING
ITEMS SHOULD BE CHECK AND INCLUDED IN A SOIL ANALYSIS:
-SOIL pH
-SOIL TEXTURE
-SOILT TEST NCDA & CS
-CONTENT
-HYDRAULIC CONDUCTIVITY & INFILTRATION RATE (HIGHLY RECOMMENDED)
3. ANY SOILS THAT ARE USED IN THE CONSTRUCTION OF THE BMP MUST MEET THE FOLLOWING
REQUIREMENTS:
-MIX MUST BE UNIFORM AND FREE OF MATERIAL GREATER THEN 2" (STONES, STUMPS, ROOTS,
ETC.)
-TEXTURE SHOULD BE LOAMY SAND, WITH NO MORE THEN 10% CLAY

Weeding
Weeding is often necessary in the first growing season, particularly if herbaceous grasses are outcompeting the young woody

Disease Control
Based on monitoring observations, either insecticides or (preferably) organic means of pest and fungal control should be used.
Mowing
Mowing of perennial herbaceous grasses and wildflowers, especially once seed heads have set, promotes redistribution of seed
