1.0 General Information

This document contains stormwater calculations demonstrating compliance with
post-construction state and local stormwater regulations for the construction of
an office and warehouse for Makson, Inc. off Speedway Boulevard in Salisbury,
NC. Specifically, regulations for this area require water quality treatment of the
first flush ሺ1"ሻ storm and the attenuation of the 1 year, 24 hour storm to pre-
construction discharge rates. Larger storms are also required to pass the
system. Two above ground sand filters will be utilized to meet these
requirements.
2.0 Methodology

Site topography requires the use of two BMPs to treat the proposed built upon
areas. The water quality volume ሺܹܳ௩ ሻ required to be treated from the first flush
was calculated using the Schueler method outlined in the NCDENR Stormwater
BMP Manual. The Schueler method utilizes the following equations:

ܴ௩ ൌ 0.05 ൅ 0.9ܫ஺
ܹܸܳ ൌ 3630ܴ஽ ܴ௩ ܣ

Where ܫ஺ is the impervious fraction of the drainage area, ܴ௩ is a runoff coefficient,
ܴ஽ is the rainfall depth, ܣ is the drainage area, and ܹܳ௩ is the runoff volume.
The calculated ܹܳ௩ is 8,854 ݂ݐ ଷ for Sand Filter #1 and 2,100 ݂ݐ ଷ for Sand Filter
#2. To route the ܹܳ௩ through the sand filters, it is necessary to calculate a
modified SCS curve number to avoid underrepresenting the first flush. The
modified curve number is calculated as follows:

ܥܰ௠ ൌ 1000/ቂ10 ൅ 5ܴ஽ ൅ 10ܹܳ௩ െ10ඥܹܳ௩ଶ ൅ 1.25ܹܳ௩ ܴ஽ ቃ

The modified curve numbers were used to route the first flush using an SCS 6
hour balanced storm distribution. The 1 year, 24 hour and larger storms were
routed with standard curve numbers and an SCS type II 24 hour storm
distribution.

Two pre-construction drainage areas and eleven post-construction drainage
areas were identified.

*Drainage areas POST-CONSTRUCTION:8 and POST-CONSTRUCTION:10
consist of vegetated areas on the down slope side of the stormwater BMPs;
therefore, they are not routed through the BMPs; however, runoff from these
drainage areas are included in the peak attenuation calculations.

Routing of the required storms through the sand filters was performed using
Autodesk Storm and Sanitary Analysis (SSA) 2015.

CLEAR, GRUB AND STRIP THE AREA UNDER THE EMBANKMENT OF ALL VEGETATION AND ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS OFORGANIC MATTER AND STOCKPILE OR DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE DESIGNATED DISPOSAL AREA. PLACE TEMPORARYSEDIMENT CONTROL MEASURES BELOW BASIN AS NEEDED.2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY, VEGETATION, ORGANIC MATTER AND OTHER OBJECTIONABLE MATERIAL.PLACE THE FILL IN LIFTS NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER THE FILL EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT.3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THESKIMMER OR PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER.4. PLACE THE BARREL *TYPICALLY 4-INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCHAS SAND, GRAVEL OR CRUSHED STONE AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4-INCH LAYERS AND COMPACTIT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT EMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE PIPE FROM THEFIRM CONTACT WITH ITS FOUNDATION WHEN COMPACTING UNDER THE PIPE HAUNCHES.5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURES INSTRUCTIONS OR AS DESIGNED.6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOINT AT THE INLET OF THE BARREL PIPE. ATTACH THE FLEXIBLE JOIN TO THEBARREL PIPE AND POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACHED A ROPE TO THE SKIMMER AND ANCHOR IT TO THESIDE OF THE BASIN. THIS WILL BE USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE.7. EARTHEN SPILLWAYS - INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS,GRADE, DESIGN WIDTH AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF THE SPILLWAY. THE SPILLWAY SHOULDBE LINED WITH LAMINATED PLASTIC OR IMPERMEABLE GEOTEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG ENOUGH TO COVER THE BOTTOM AND SIDESAND EXTEND ONTO THE TOP OF THE DAM FOR ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8-INCH STAPLES OR PINS. THE FABRIC MUST BELONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE ON PIECE, NOT JOINED OR SPLICED;OTHERWISE THE WATER CAN GET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC IS INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLESECTIONS, SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTION(S) SHOULD OVERLAP THE LOWER SECTIONS(S) SO THAT WATER CANNOT FLOWUNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS.8. INLET - DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE TEMPORARY SLOPE DRAINS OR DIVERSION WITH OUTLET PROTECTION TODIVERT SEDIMENT LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP EFFICIENCY.9. EROSION CONTROL - CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMIZED. DIVERT SURFACE WATER AWAY FROM THE BARE AREAS.COMPLETE THE EMBANKMENT BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND ALL OTHER DISTURBED AREAS ABOVETHE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY AFTER CONSTRUCTION.10.

EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUSTAROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.2. REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE-ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR AROUND THEM.3. IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING ON THE WILL MAKE THE SKIMMER BOB UP AND DOWN ANDDISLODGE THE DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSOCHECK THE ORIFICE INSIDE THE SKIMMER TO SEE IF IT IS CLOGGED; IF SO REMOVE THE DEBRIS.4. IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BYFLUSHING WITH WATER. BE SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.5. CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. CHECK THEEMBANKMENT, SPILLWAYS AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRSIMMEDIATELY. REMOVE ALL TRASH AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS.6. FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN.

1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
