Erosion and Sediment Control Plan checklist for plan reviewers
Updated 1 Dec 2014
An erosion and sediment control plan is a document which illustrates the measures used to control erosion
and sedimentation during construction. All measures follow the Virginia Erosions and Sediment Control

[Square Brackets] are County Code references, (Curved Brackets; are policy references, and (regular
parenthesis) are explanatory. Links to reference documents are provided where possible.

cation information:
Completed WPO application and fees, with owners signature [County Code ]-3 �.4.3.2,
_�
18=32.3.9, 17 ;lrticle H] Erosion Control plans require a Water Protection Ordinance
WPO application and original owner's siaiature. No review is provided without
application, owner signature and fees. This is true even for revisions. It is important that
�n the owner be aware of comments and re -submittals, and this is the county assurance.
l" �" Copies of federal and state permits for any wetland or stream disturbance. (Army Corps,
VDEQ, etc) [ 17-604, 18-3 2.1.2, 14-3 11 ]
V#�S/P:
SWPPP, PPP, SWMP approvals obtained where necessary. In most cases, the erosion
control plan will not be submitted independently, but will be part of a Stormwater
Pollution Prevention Plan (SWPPP). Unless exempt, it will be approved with the
SWPPP.
Title information:
./ Project title. Titles should be appropriate. It should be an erosion control plan, not a
stormwater plan, or site plan, etc. In some cases a WPO package will contain a
stormwater plan and a mitigation plan, but they should be on separate sheets with keys
and page titles.
,-�?rofessional seal, with original signature and date for professionally prepared plans.
Content: The erosion control plan must not contain information regarding permanent
improvements that do not also appear on other plans. Erosion control plans are
temporary documents that are discarded after projects are complete.
EX titi tg conditions plan view information:
accurate current existing topography at the time of submittal, including all existing site
features, and any recent disturbances, all at a legible scale
date and source of the topographic information: All topography should be at least visually
field verified by the designer within the last year. Adequate erosion control cannot be
/ designed without accurate topography and drainage areas.
WPO buffer limits; 100' from stream or wetland bank, 200' from reservoirs, or
floodplain limit if greater.
No buffer disturbances without WPO Program Authority approval and a mitigation plan.
floodplain limits, including 100yr flood limits for any channel with a drainage area of
50+ acres.

inlet protection on proposed drainage systems, which are only possible to install upon
completion of grading, may be denied without further review.
no erosion control neasures in the wat• of construction access or grading. Diversion
dikes or silt fence are not placed in the middle of the site, or through access or grading.
Sediment traps are not under or on top of fill material or held up by retaining walls.
Construction entrances are not on fill, etc. If the concept for site protection is not
adequate in this regard, further review of the plan may not be possible.
existing soil boundaries are shown with labels. Areas already disturbed are indicated,
with constructed fill depth or cut noted.
c itical erosion areas are identified, areas of constructed slopes, areas near property lines
djacent off -site disturbances are shown with erosion control facilities
a stockpile location.
where cur or fill balances have a 10,000 cubic yard deficit or more, plans should not be
approved without a waste area identified. This must be on -site, or on another approved
and permitted site. (Don't make the inspectors chase trucks to find the dump site
f violation.)
a staging and parking area, or other construction related areas
diversion dikes are used to direct drainage to traps and basins
z- silt fence is not used across contours in place of diversion dikes.
silt fence is limited to areas of sheet flow with'/4 acre per 100ft of level on -grade silt
fence. Plans showing only silt fence, without sediment trapping measures, should not be
approved unless they meet this criteria and fill dirt is minimal.
all su ales and low points at the perinieter o 'the site have a sediment trap or basin. Silt
fence in swales is typically not adequate. Check dams do not substitute for traps.
Diversions which travel more than 100ft, or go in and out of swales, are usually not
/- maintainable in the field. If the concept_for site protection is not adequate in this regard,
/ further review of the plan may not be possible.
✓✓✓ temporary slope drains (TSD) or diversions are provided to prevent discharge over

inlet protection (IP) on all inlets
culvert inlet protection (CIP) on all culvert inlets
outlet protection (OP) on all outlets
all watercourses are protected and encroachments minimized
stream crossing (USC,SC) and diversions are provided at all stream crossings.
r adequate channels (MS-19) provided for each outfall (see Design Manual for minimum

/ all traps and basins are shown with proposed contours. Simple boxes or symbols are not
sufficient, in most cases, to determine layout or bond amounts.
