YCCD Standard Erosion
& Sediment (E&S) Control Plan Format
Background &
Introduction
The York
County Conservation District (YCCD) E&S staff met with our E&S
Stakeholder Taskforce on
The YCCD has
found that the majority of plan review comments listed in our technical
deficiency letters are related to missing standard notes, construction details,
and design information as well as incorrect and out-of-date notes.
The District has also found that many notes provided by plan preparers
are inconsistent with the District’s standard notes, have been duplicated on
the plans, and in many cases are simply not applicable to the project at hand.
It appears that unnecessary information is placed on plans due to
out-of-date plan templates and to err on the “safe” side to avoid missing
required information. Placing such
information on the plans effectively slows down the plan review process and
confuses contractors in the field. In
addition to the issues above, it is often difficult to locate standard
information on the plans as each individual plan preparer has a different idea
of where the information should be placed on the plans.
The intent of the standard plan format is to encourage the use of
standard information (ex. standard notes, construction details, and worksheets)
provided in the April 15, 2000 E&S Program Manual and to organize and locate
the required information in a more predictable, consistent, and easier-to-read
manner. While DEP does not
require or allow the YCCD to require a specific plan format, it is widely agreed
that voluntarily utilizing such a format would be in the interest of permit
applicants as it would significantly reduce the time required for District staff
to review and approve E&S plans and process NPDES permits.
In addition to improving plan review and permit processing times, the
benefits of standardizing the format include:
● the time saved providing correct details and notes
will allow plan preparer additional time to focus on providing more effective
and practical conceptual designs while at the same time ensuring that critical
details and information required to
construct BMPs in the field are not overlooked.
● contractors will become more familiar with
regulatory requirements as construction
details, standard notes, etc. become more consistent and predictable
● will conserve paper and limited District file
space,
● and most importantly will allow contractors and
District staff to locate information on
plans more efficiently in the field so that they can focus their limited time
and resources on making sure the Best Management Practices (BMPs) outlined in
the E&S plans are implemented on the ground.
Plan
Drawings
1)
First sheet in set to include (with
original plan date or most recent revision date consistent with narrative title
sheet):
▪ Location map –
Locate on first sheet in upper right hand corner.
Fold plans to expose location map.
- erosion
and sediment control legend
▪ Standard erosion and sediment
control note section
- List Standard
notes
# 1, 2, 7, 23-27
- All notes not applicable to the project at hand should be removed from the plan drawings.
- Refer to the District’s standard
note list and technical
plan review checklist for recommended locations of all other
standard notes.
▪ Site-specific construction
sequence. Left side of sheet.
- Standard
notes # 3 & 4
should be listed as stages 1 & 2 of the construction sequence
respectively.
-
Standard BMP installation & maintenance notes should not be
placed within the construction sequence.
▪ Resolutions to the identified site-specific soil limitations.
▪ Stabilization specifications
-
standard
stabilization notes #
17-19
-
topsoil replacement instructions
-
surface roughening instructions
-
straw mulch anchoring instructions
-
permanent seed, lime, fertilizer,
and mulching (include seeding dates and seed mixes for varying site conditions
– ex. wet areas, steep slopes, etc.)
-
temporary seed, lime, fertilizer,
and mulching
▪ PA One Call Decal and phone
number
▪ DEP Approval Stamp – leave
at least 3” by 4” space in lower right corner for placement of approval
stamp. Fold plans to expose stamp.
2)
Second sheet to serve as an overview sheet of
the existing conditions of the entire project shown with 1” = 100’
mapping scale to include: (overview
sheets are not necessary for smaller projects which can be shown on one 1”=
50’ or larger scale sheet and in which all the below information can be shown
on the same sheet without producing too much clutter)
▪ Existing contours and land use (ex.
woods, fields, etc.)
▪ All existing
improvements
▪ NPDES permit
boundary – includes entire parcel and any offsite right-of-
ways
▪ All
Waters of the Commonwealth including 100 yr. floodway boundary.
▪ North arrow (upper left corner)
3) Third sheet to serve as an overview sheet with proposed improvements and maximum during construction BMP drainage areas to include 1”=100’ scale or larger with
▪
Soils legend
▪
All proposed improvements, proposed contours, and BMPs.
▪
Phase boundaries
▪
BMP maximum during construction drainage areas for all BMPs (ex. basins, traps,
channels/berms, inlets requiring inlet protection).
▪
Color-coded (preferred) drainage area boundaries with the respective BMP clearly
labeled.
▪
Drainage area acreage is identified
with the BMP labeling or in a BMP drainage area table.
▪
Pre-development and post-development BMP drainage areas are unnecessary unless
they represent the maximum during construction BMP drainage areas.
▪
Drainage areas may be located on the larger 1”=50’ scale drawings if
drawings do not become too busy.
4)
Fourth sheet + to include 1”=50’ scale or larger scale drawings with:
▪ Sheet matchlines with
adjoining sheet numbers
▪
Existing and proposed contours with maximum 2’ contour interval
▪
All proposed improvements and BMP locations
▪
All waters of the Commonwealth
▪
North arrow (upper left corner)
▪
Limits of disturbance,
5)
Clearly label the plan drawings as “Erosion and Sediment Control.”
6)
Construction details should be placed after the 1”= 50’ scale or larger plan
drawings.
7) Use the standard E&S construction details provided in the E&S Program Manual (with site-specific modification(s) as necessary). The basin, trap, and channel standard construction details utilize tables for the elevations, dimensions and type of materials necessary to construct each BMP thereby eliminating the need for multiple redundant construction details.
8)
Do not place PCSM construction details on the E&S plans.
The E&S plan and the PCSM
plan must be separate stand-alone plans.
9)
Place all standard BMP installation and maintenance notes with the relevant BMP
standard construction detail. See
standard notes #10-16.
Avoid placing notes in long lists separate from the standard construction
details.
10)
Keep all BMP construction details grouped together and on the same sheet when
possible. For
example, a sediment basin requires an outlet structure detail #4, berm
construction detail #3, emergency spillway detail #8, baffle detail #9, clean
out stake detail , dewatering facility detail #10, trash rack detail and
anti-seep collar detail which should all be grouped together so the contractor
can more easily locate the information.
11) Place all construction details necessary for the builder on one sheet or grouped together on one sheet. These details include:
▪
Typical on-lot details showing the required BMPs for each lot
layout (ex. sloping to front, sloping to back, sloping to corner, etc.)
▪
Rock construction entrance (RCE)
▪
Broad-based dip
▪
Pumped water filter bag
▪
Silt fence detail with the rock filter outlet repair detail
▪
Compost filter sock
▪
Inlet protection and inlet berm
▪
Erosion control blanket slope installation detail
12)
Avoid using all capital letters on the plan drawings
which are difficult to read and give the appearance of “shouting” at the
contractor.
13)
Utilize Arial
font for easier to read text. Make
sure the font is large enough to easily read in the field.
14)
Avoid use of excessive “flags” that clutter the plan drawings.
15)
Avoid the use of cross-hatching to
represent the application of an erosion control blanket on steep slopes.
Recommend that a light shading be used in lieu of cross-hatching on
slopes and the use of station numbers or channel breaks to indicate the types of
channel lining(s) to be used.
16)
Avoid overlaying three layers of contours on the drawings (ex.
existing, temporary, and final contours of basins).
17)
Utilize “blow-ups” of critical areas such as stream crossings and
other heavily detailed areas that are difficult to read.
Plan
Narrative
1)
Organize the plan narrative in order with the YCCD’s
Technical Plan Review Checklist
(11 required items). The
narrative should be composed of the below 10 bulleted items and little else.
▪
Title Sheet with original plan
date or most recent revision date consistent with drawing sheets
▪
Plan preparer’s name,
contact information, and qualifications (click
for sample
in word format)
▪
Introduction/Summary
-
Discuss project location and
nature of project i.e. proposed land use
-
Brief summary of the BMPs to be
utilized so an untrained third party
-
Existing land use.
-
Past land use (at least past 50
years, discuss any soil contamination/potential pollution issues as a result of
past land use(s)).
-
Discuss receiving watercourse(s)
and the Chapter 93 and/or existing use designation.
▪
USGS Topographic Map with
project boundaries clearly outlined and
offsite drainage areas clearly delineated and identified.
▪
List of all soil types
occurring on the project site with site-specific soil
▪
Channel design information.
-
Standard Worksheet #18 information for all channels (or) all
standard worksheets required for channel design methodology (ex.
- Standard worksheet #21
for all channels for both temporary and permanent
channel lining condition. Channel
design software output/spreadsheets
are unnecessary.
- Channel lining
manufacturers’ specifications including permissible
velocity or shear stress.
▪
Sediment basin design information.
- Copies of offsite
stormwater easements.
- Standard Worksheets
12, 13, 14, 15, & 16 with complete principal
(including skimmers with manufacturer’s specs.) and emergency
spillway discharge calculations.
▪
Sediment trap design information.
- Copies of offsite
stormwater easements.
- Standard Worksheets
#8 & 14 with complete principal discharge
calculations.
- Include a discharge analysis and photos for any concentrated
flows
- Copies of offsite stormwater easements.
▪
Alternative BMP design information.
2)
Use the standard worksheets for sediment
basins, traps, channels, and outlet protection provided in the E&S Program
Manual. This ensures all the
required information is provided and is familiar to the plan reviewer which
speeds up the plan review process.
3)
Standard notes, standard construction details, the construction sequence,
drainage areas, and stabilization specifications are not needed in the
plan narrative given this information
is already provided on the plan drawings.
4)
PCSM operation and maintenance notes, hydrographs, and design calculations
should not be included in the E&S plan narrative.
The E&S plan and the PCSM plan
must be separate stand-alone plans.
5)
Avoid placing and binding the NOI, PNDI, Act 14 notifications, GIF forms, and
other NPDES permit information in the E&S plan narrative.
6)
Make double-sided pages to conserve paper and file space.
7)
Avoid using 3-ring binders which use up valuable file space.
8)
Utilize Arial font for easier to read text.
9)
Wetland determination letters, delineation reports, DEP permits or completed
permit applications, and US Army Corp of Engineers Jurisdictional Determination
letters should be submitted as separate documents not
bound in the E&S plan narrative.
Other Recommendations
1) Submit only folded plan
drawings (due to District’s filing system and limited file space).
Avoid folding each sheet separately.
2) Avoid submitting the
entire land development set of drawings and details (ex. landscaping plans,
grading plans, sanitary sewer profiles, lighting plans, etc.).
Only the E&S drawings and details are necessary and should be
separate stand-alone plans.
4) Provide specific page
numbers and locations of information on the NOI checklist.
5) Use the most current NOI
form and District plan review application forms.
6) Use the YCCD/DEP
E&S Control Plan Technical Review Checklist dated
7) When re-submitting
revised plans, highlight the revisions/additions on the District’s copy and
provide an item-by-item detailed response letter.
Also highlight any other revisions made that were not requested by the
District.
8) Submit half-size plan drawings (as long as legible) upon plan approval for larger projects. Half-size plans take up less file space, conserve paper, and are easier to handle in the field.

Disclaimer: The standard plan format recommendations and the accompanying Delta Ridge E&S plan are in no way intended to address the Best Management Practice (BMP) design of the project. Using the standard plan format recommendations is not intended to encourage or necessitate a “cookie cutter” or a “one size fits all” plan. Every site is unique (as can be observed on the Delta Ridge E&S plan) and will require a site-specific plan dependent on a variety of factors including but not limited to the nature and complexity of the project, soil types, topography, cut/fill, proximity to streams and wetlands, and the duration and extent of the earth disturbance.
