STORMWATER MANAGEMENT:
WATER QUALITY:
TO ADDRESS RUNOFF QUALITY REQUIREMENTS SET FORTH IN 9VAC25-870-65, THE VRRM
SPREADSHEET, SHOWED THAT THE PROJECT REQUIRES A TOTAL PHOSPHOROUS (TP) REDUCTION
OF 2.07 LB/YR.
TO ACHIEVE THE REQUIRED TP REDUCTION, A STORMTECH BMP WITH TWO ISOLATOR ROWS,
THAT ACHIEVES 40% TP REMOVAL, WAS SELECTED TO TREAT A 1.14LB/YR OF RUNOFF WHICH
FLOWS THROUGH THE SITE (55.07% OF SITE). THE REMAINING 0.93 LB/YR TP REDUCTION WILL
BE MET WITH A PURCHASE OF PHOSPHOROUS CREDITS FOR THAT AMOUNT. THUS, ALL RUNOFF
QUALITY REQUIREMENTS FOR THIS DEVELOPMENT ARE ACHIEVED.
WATER QUANTITY:
SWM QUANTITY IS SATISFIED BY ANALYZING CONCENTRATED RUNOFF FROM THE
DEVELOPMENT AT A POINT OF ANALYSIS (PDA) AT THE WESTERN CORNER OF THE
DEVELOPMENT PROPERTY. 9VAC25-870-66-B(3) REQUIRES THAT CONCENTRATED RUNOFF FROM
DEVELOPMENT AT THE POA MEET THE ENERGY BALANCE EQUATION. TO ACHIEVE THIS, ALL
CONCENTRATED RUNOFF FROM THE SITE WILL BE ROUTED TO TWO UNDERGROUND DETENTION
FACILITIES (STORMTECH MC-3500 & STORMTECH SC-310).
THE SITE WAS DIVIDED INTO TWO DRAINAGE AREAS, EACH DRAINAGE AREA FLOWS INTO A
DETENTION SYSTEM. THE FIRST DRAINAGE AREA IS 1.849 ACRES WHICH FLOWS INTO STORMTECH
MC-3500. THE SECOND DRAINAGE AREA IS 0.169 ACRES FLOWS INTO STORMTECH SC-310.
BOTH DRAINAGE AREA 1 & 2 RUNOFF FROM THE DEVELOPMENT AT A POINT OF ANALYSIS
(POA) AT THE WESTERN CORNER OF THE DEVELOPMENT PROPERTY.
THE RUNOFF FROM THE DETENTION SYSTEMS MEETS THE ENERGY BALANCE EQUATION.
9VAC25-870-66-C REQUIRES THAT THE POST-DEV 10-YEAR RUNOFF IS CONTAINED WITHIN
THE SYSTEM AT THE POINT OF OUTFALL, THIS CONDITION HAS ALSO BEEN SATISFIED.

THE APPLICANT SHALL:
1) IMPROVE THE CHANNELS TO A CONDITION WHERE A TEN-YEAR STORM WILL NOT
OVERTOP THE BANKS AND A TWO-YEAR
STORM WILL NOT CAUSE EROSION TO CHANNEL THE BED OR BANKS; OR
2) IMPROVE THE PIPE OR PIPE SYSTEM TO A CONDITION WHERE THE TEN-YEAR STORM
IS CONTAINED WITHIN THE
APPURTENANCES;
3) DEVELOP A SITE DESIGN THAT WILL NOT CAUSE THE PRE -DEVELOPMENT PEAK
RUNOFF RATE FROM A TWOYEAR STORM TO
INCREASE WHEN RUNOFF OUTFALLS INTO A NATURAL CHANNEL OR WILL NOT CAUSE
THE PREDEVELOPMENT PEAK RUNOFF RATE
FROM A TEN-YEAR STORM TO INCREASE WHEN RUNOFF OUTFALLS INTO A MANMADE
CHANNEL; OR
4) PROVIDE A COMBINATION OF CHANNEL IMPROVEMENT, STORMWATER DETENTION OR
OTHER MEASURES WHICH IS
SATISFACTORY TO THE VESCP AUTHORITY TO PREVENT DOWNSTREAM EROSION.
D. THE APPLICANT SHALL PROVIDE EVIDENCE OF PERMISSION TO MAKE THE
IMPROVEMENTS.
E. ALL HYDROLOGIC ANALYSES SHALL BE BASED ON THE EXISTING WATERSHED
CHARACTERISTICS AND THE ULTIMATE DEVELOPMENT
CONDITION OF THE SUBJECT PROJECT.
F. IF THE APPLICANT CHOOSES AN OPTION THAT INCLUDES STORMWATER DETENTION,
HE SHALL OBTAIN APPROVAL FROM THE VESCP
OF A PLAN FOR MAINTENANCE OF THE DETENTION FACILITIES. THE PLAN SHALL SET
FORTH THE MAINTENANCE REQUIREMENTS OF THE
FACILITY AND THE PERSON RESPONSIBLE FOR PERFORMING THE MAINTENANCE.
G. OUTFALL FROM A DETENTION FACILITY SHALL BE DISCHARGED TO A RECEIVING
CHANNEL, AND ENERGY DISSIPATORS SHALL BE
PLACED AT THE OUTFALL OF ALL DETENTION FACILITIES AS NECESSARY TO PROVIDE A
STABILIZED TRANSITION FROM THE FACILITY TO THE
RECEIVING CHANNEL.
H. ALL ON -SITE CHANNELS MUST BE VERIFIED TO BE ADEQUATE.
I. INCREASED VOLUMES OF SHEET FLOWS THAT MAY CAUSE EROSION OR
SEDIMENTATION ON ADJACENT PROPERTY SHALL BE
DIVERTED TO A STABLE OUTLET, ADEQUATE CHANNEL, PIPE OR PIPE SYSTEM, OR TO A
DETENTION FACILITY.
J. IN APPLYING THESE STORMWATER MANAGEMENT CRITERIA, INDIVIDUAL LOTS OR
PARCELS IN A RESIDENTIAL, COMMERCIAL OR
INDUSTRIAL DEVELOPMENT SHALL NOT BE CONSIDERED TO BE SEPARATE DEVELOPMENT
PROJECTS. INSTEAD, THE DEVELOPMENT, AS A
WHOLE, SHALL BE CONSIDERED TO BE A SINGLE DEVELOPMENT PROJECT. HYDROLOGIC
PARAMETERS THAT REFLECT THE ULTIMATE
DEVELOPMENT CONDITION SHALL BE USED IN ALL ENGINEERING CALCULATIONS.
K. ALL MEASURES USED TO PROTECT PROPERTIES AND WATERWAYS SHALL BE
EMPLOYED IN A MANNER WHICH MINIMIZES
IMPACTS ON THE PHYSICAL, CHEMICAL AND BIOLOGICAL INTEGRITY OF RIVERS, STREAMS
AND OTHER WATERS OF THE STATE.
L. ANY PLAN APPROVED PRIOR TO JULY 1, 2014, THAT PROVIDES FOR STORMWATER
MANAGEMENT THAT ADDRESSES ANY FLOW
RATE CAPACITY AND VELOCITY REQUIREMENTS FOR NATURAL OR MAN-MADE CHANNELS
SHALL SATISFY THE FLOW RATE CAPACITY AND
VELOCITY REQUIREMENTS FOR NATURAL OR MAN-MADE CHANNELS IF THE PRACTICES
ARE DESIGNED TO
I. DETAIN THE WATER QUALITY VOLUME AND TO RELEASE IT OVER 48 HOURS;
II. DETAIN AND RELEASE OVER A 24-HOUR PERIOD THE EXPECTED RAINFALL RESULTING
FROM THE ONE YEAR, 24- HOUR
STORM; AND
III. REDUCE THE ALLOWABLE PEAK FLOW RATE RESULTING FROM THE 1.5, 2, AND
10-YEAR, 24-HOUR STORMS TO A LEVEL THAT
IS LESS THAN OR EQUAL TO THE PEAK FLOW RATE FROM THE SITE ASSUMING IT WAS
IN A GOOD FORESTED CONDITION, ACHIEVED
THROUGH MULTIPLICATION OF THE FORESTED PEAK FLOW RATE BY A REDUCTION
FACTOR THAT IS EQUAL TO THE RUNOFF VOLUME
FROM THE SITE WHEN IT WAS IN A GOOD FORESTED CONDITION DIVIDED BY THE
RUNOFF VOLUME FROM THE SITE IN ITS
PROPOSED CONDITION, AND SHALL BE EXEMPT FROM ANY FLOW RATE CAPACITY AND
VELOCITY REQUIREMENTS FOR NATURAL OR
MAN-MADE CHANNELS AS DEFINED IN ANY REGULATIONS PROMULGATED PURSUANT TO
§ 10.1-562 OR 10.1-570 OF THE ACT.
M. FOR PLANS APPROVED ON AND AFTER JULY 1, 2014, THE FLOW RATE CAPACITY
AND VELOCITY REQUIREMENTS OF § 10.1-561 A
OF THE ACT AND THIS SUBSECTION SHALL BE SATISFIED BY COMPLIANCE WITH WATER
QUANTITY REQUIREMENTS IN THE STORMWATER
MANAGEMENT ACT (§ 10.1-603.2 ET SEC. OF THE CODE OF VIRGINIA) AND ATTENDANT
REGULATIONS, UNLESS SUCH LANDDISTURBING ACTIVITIES ARE IN ACCORDANCE WITH
4VAC50-60-48 OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM (VSMP)
PERMIT REGULATIONS.
N. COMPLIANCE WITH THE WATER QUANTITY MINIMUM STANDARDS SET OUT IN
4VAC50-60-66 OF THE VIRGINIA STORMWATER
