PERIOD, A TEMPORARY VEHICULAR STREAM CROSSING CONSTRUCTED OF NONERODIBLE MATERIAL SHALL BE PROVIDED.
ES-19: THE BED AND BANKS OF A WATERCOURSE SHALL BE STABILIZED IMMEDIATELY AFTER WORK IN THE WATERCOURSE
IS COMPLETE.
ES-20: TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT
FINAL GRADE BUT WILL REMAIN DORMANT FOR LONGER THAN 14 DAYS.
ES-21: UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING STANDARDS IN ADDITION
TO OTHER APPLICABLE CRITERIA:
A. NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME.
B.EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES.
C.EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN APPROVED SEDIMENT TRAPPING
DEVICE OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OF
OFF -SITE PROPERTY.
D. MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO MINIMIZE EROSION AND
PROMOTE STABILIZATION.
E. RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THESE REGULATIONS.
F. APPLICABLE SAFETY REGULATIONS SHALL BE COMPLIED WITH.
ES-22: WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED OR PUBLIC ROADS, PROVISIONS SHALL BE
MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT
IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF
EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROAD BY SHOVELING OR SWEEPING AND TRANSPORTED TO A
SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS
MANNER.
ES-23: ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL
SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY
THE LOCAL PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE
DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND
SEDIMENTATION.
ES-24: ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT
RAINFALL. THEY WILL BE INSPECTED FOR UNDERMINING, DETERIORATION, EROSION, AND EXCESS DEPOSITED MATERIAL. ALL
DEFICIENCIES WILL BE CORRECTED IMMEDIATELY. EXCESS MATERIAL WILL BE SPREAD ON THE SITE IN A MANNER WHICH
WILL NOT LEAD TO FURTHER EROSION POTENTIAL.
ALL AREAS DISTURBED BY CONSTRUCTION SHALL BE STABILIZED WITH TEMPORARY OR PERMANENT
SEEDING WITHIN 7 DAYS FOLLOWING FINISH GRADING. SEEDING SHALL BE DONE ACCORDING TO
STANDARD & SPECIFICATION 3.31 TEMPORARY OR 3.32 PERMANENT SEEDING, OF THE VIRGINIA
EROSION AND SEDIMENT CONTROL HANDBOOK AND DCR TECHNICAL BULLETIN #4. APPLICATION

MINIMUM STANDARDS
1. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final
grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to
denuded areas that may not be at final grade but will remain dormant for longer than 14 days. Permanent
stabilization shall be applied to areas that are to be left dormant for more than one year.
PP Y
2. During construction of the project, soil stock piles and borrow areas shall be stabilized or protected with
sediment trapping measures. The applicant is responsible for the temporary protection and permanent
stabilization of all soil stockpiles on site as well as borrow areas and soil intentionally transported from the
project site.
3. A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized.
Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform,
mature enough to survive and will inhibit erosion.
4. Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap
sediment shall be constructed as a first step in any land -disturbing activity and shall be made functional
before upslope land disturbance takes place.
5. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions
immediately after installation.
6. Sediment traps and sediment basins shall be designed and constructed based upon the total drainage area
to be served by the trap or basin.
a. The minimum storage capacity of a sediment trap shall be 134 cubic yards per acre of drainage area and
the trap shall only control drainage areas less than three acres.
b. Surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal
to three acres shall be controlled by a sediment basin. The minimum storage capacity of a sediment basin
shall be 134 cubic yards per acre of drainage area. The outfall system shall, at a minimum, maintain the
structural integrity of the basin during a 25-year storm of 24-hour duration. Runoff coefficients used in
runoff calculations shall correspond to a bare earth condition or those conditions expected to exist while the
sediment basin is utilized.
7. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that
are found to be eroding excessively within one year of permanent stabilization shall be provided with additional
slope stabilizing measures until the problem is corrected.
8. Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or
permanent channel, flume or slope drain structure.
9. Whenever water seeps from a slope face, adequate drainage or other protection shall be provided.
10. All storm sewer inlets that are made operable durin construction shall be protected so that
P 9
sediment -laden water cannot enter the conveyance system without first being filtered or otherwise treated to
remove sediment.
11. Before newly constructed stormwater conveyance channels or pipes are made operational, adequate outlet
protection and any required temporary or permanent channel lining shall be installed in both the conveyance
channel and receiving channel.
12. When work in a live watercourse is performed, precautions shall be taken to minimize encroachment,
control sediment transport and stabilize the work area to the greatest extent possible during construction.
Nonerodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be
used for these structures if armored by nonerodible cover materials.
13. When a live watercourse must be crossed by construction vehicles more than twice in any six-month
period, a temporary vehicular stream crossing constructed of nonerodible material shall be provided.
14. All applicable federal, state and local requirements pertaining to working in or crossing live watercourses
shall be met.
15. The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is
completed.
16. Underground utility lines shall be installed in accordance with the following standards in addition to other
applicable criteria:
a. No more than 500 linear feet of trench may be opened at one time.
b. Excavated material shall be placed on the uphill side of trenches.
c. Effluent from dewatering operations shall be filtered or passed through an approved sediment trapping
device, or both, and discharged in a manner that does not adversely affect flowing streams or off -site
property.
d. Material used for backfilling trenches shall be properly compacted in order to minimize erosion and promote
stabilization.
e. Restabilization shall be accomplished in accordance with this chapter.
f. Applicable safety requirements shall be complied with.
17. Where construction vehicle access routes intersect paved or public roads, provisions shall be made to
minimize the transport of sediment by vehicular tracking onto the paved surface. Where sediment is
transported onto a paved or public road surface, the road surface shall be cleaned thoroughly at the end of
each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment
control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This
provision shall apply to individual development lots as well as to larger land -disturbing activities.
18. All temporary erosion and sediment control measures shall be removed within 30 days after final site
stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the VESCP
authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures
shall be permanently stabilized to prevent further erosion and sedimentation.
19. Properties and waterways downstream from development sites shall be protected from sediment deposition,
erosion and damage due to increases in volume, velocity and peak flow rate of stormwater runoff for the
stated frequency storm of 24-hour duration in accordance with the following standards and criteria. Stream
restoration and relocation projects that incorporate natural channel design concepts are not man-made
channels and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made
channels:
a. Concentrated stormwater runoff leaving a development site shall be discharged directly into an adequate
natural or man-made receiving channel, pipe or storm sewer system. For those sites where runoff is
discharged into a pipe or pipe system, downstream stability analyses at the outfall of the pipe or pipe system
shall be performed.
b. Adequacy of all channels and pipes shall be verified in the following manner:
(1) The applicant shall demonstrate that the total drainage area to the point of analysis within the channel is
100 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 10-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 10-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 10-year storm will not overtop the banks and a two-year
storm will not cause erosion to the channel, the bed, or the banks;
(2) Improve the pipe or pipe system to a condition where the 10-year storm is contained within the
appurtenances;
(3) Develop a site design that will not cause the pre -development peak runoff rate from a two-year storm
to increase when runoff outfalls into a natural channel or will not cause the pre -development peak runoff
rate from a 10-year storm to increase when runoff outfalls into a man-made 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.
I. 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 § 62.1-44.15:54 or 62.1-44.15:65 of the Act.
m. For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements of §
62.1-44.15:52 A of the Act and this subsection shall be satisfied by compliance with water quantity
requirements in the Stormwater Management Act 62.1-44.15:24 et se . of the Code of Virginia) and
q 9 (§ q 9 )
attendant regulations, unless such land -disturbing activities (i) are in accordance with provisions for time
limits on applicability of approved design criteria in 9VAC25-870-47 or grandfathering in 9VAC25-870-48 of
the Virginia Stormwater Management Program (VSMP) Regulation, in which case the flow rate capacity and
velocity requirements of § 62.1-44.15:52 A of the Act shall apply, or (ii) are exempt pursuant to §
62.1-44.15:34 C 7 of the Act.
n. Compliance with the water quantity minimum standards set out in 9VAC25-870-66 of the Virginia
Stormwater Management Program (VSMP) Regulation shall be deemed to satisfy the requirements of this
subdivision 19.
