ONE HUNDRED TIMES GREATER THAN THE CONTRIBUTING DRAINAGE AREA OF THE
PROJECT IN QUESTION; OR
2) (A) NATURAL CHANNELS SHALL BE ANALYZED BY THE USE OF A TWO-YEAR STORM
TO VERIFY THAT STORMWATER WILL NOT
OVERTOP CHANNEL BANKS NOR CAUSE EROSION OF CHANNEL BED OR BANKS.
(B) ALL PREVIOUSLY CONSTRUCTED MAN-MADE CHANNELS SHALL BE ANALYZED BY
THE USE OF A TEN-YEAR STORM TO VERIFY
THAT STORMWATER WILL NOT OVERTOP ITS BANKS AND BY THE USE OF A TWO-YEAR
STORM TO DEMONSTRATE THAT STORMWATER
WILL NOT CAUSE EROSION OF CHANNEL BED OR BANKS; AND
(C) PIPES AND STORM SEWER SYSTEMS SHALL BE ANALYZED BY THE USE OF A
TEN-YEAR STORM TO VERIFY THAT STORMWATER
WILL BE CONTAINED WITHIN THE PIPE OR SYSTEM.
C. IF EXISTING NATURAL RECEIVING CHANNELS OR PREVIOUSLY CONSTRUCTED
MAN-MADE CHANNELS OR PIPES ARE NOT ADEQUATE,
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 SEQ. 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
MANAGEMENT PROGRAM (VSMP) PERMIT REGULATIONS SHALL BE DEEMED TO SATISFY

Foxtail Millet - 20 lbs/acre. Add 20 lbs/acre Indian grass when slopes
are greater than 3:1.
August 16 through October 31:

greater than 3:1.
November 1 through February 15:
Kentucky 31 Fescue - 128 lbs/acre; Red Top Grass - 2 lbs/acre; Winter
Rye - 20 lbs/acre. Add 20 lbs/acre Indian grass on slopes greater
than 3:1.
MULCHING SPECIFICATIONS:
Straw or hay at a rate of 2 tons/acre. Must be anchored. Spread with
mulch blower or by hand.
LIME AND FERTILIZER SPECIFICATIONS:
Lime and fertilizer needs should be determined by soil tests. Soil tests
may be preformed by the Cooperative Extension Service Soil Testing
Laboratory at VPI&SU, or by a reputable commercial laboratory.
Information concerning the State Soil Testing Laboratory is available from
CITY Extension Agents. Under unusual conditions where it is not possible
to obtain a soil test, the following soil amendments will be applied:
For Permanent Seeding: Seeded areas shall be limed at a rate of 2 tons
per acre, and fertilized at a rate of 1,000 lbs. per acre of 10-20-10 (10
lbs. per 1,000 square feet) or equivalent.
For Temporary Seeding: Seeded areas shall be limed at a rate of 2 tons
per acre, and fertilized at a rate of 600 lbs. per acre of 10-20-10 (10
lbs. per 1,000 square feet) or equivalent.
