General recommendations to the design engineer before preparing Erosion Control Materials for review.
A general understanding of EPA’s Clean Water Act and specifically NPDES is helpful to understand where in the big
picture erosion, sediment and pollution control come into play.
Review the State’s Requirements and Guidance for Stormwater Management Plans as many of the requirements
and guidance documents from the State’s Construction Permit and MS4 permit are reflected by what is being
called out in the City’s Criteria.
There are many classes to better understand the overall goal of these materials taking these types of classes can
help in the successful compilation of materials.
These Erosion Control Materials are intended to familiarize anyone with the characteristics of the project. Based
upon the site and the anticipated activities of a project could contain various pollution sources. As a source many
pollutants can be identified prior to a project. Each pollutant identified will need a proposed way of being
controlled from leaving the project. These planning documents are prepared as an honest attempt to prevent and
control these pollutants through the project completion and through full site stabilization to minimize impact of
exposed pollutants.
Please contact or consult with others in your profession who might have already prepared erosion control
materials of finding prior examples that may have been submitted already. These resources can help gain a better
understanding as to what should be incorporated when designing Erosion Control Materials.
These documents should be prepared so that it is clear enough that contractor, engineer, or inspector alike would
easily be able to follow materials.
Each control measure has a designed function and limitation. Knowing these controls, what are their limitations,
how they are to be installed, maintained and removal when sequenced through a project can be the difference
between successful plans and non-compliance for the field application. Selecting the best device or practice, or
latest technology may be for nothing if not applied correctly or not a practical control measure in a specific
application in the field. It is important to get feedback from an experienced contractor or erosion control installer
about these types of devices and what has their experience been with the selected device in varying
circumstances. Their experience will help shape the practicality of that control being used.
Always try to build off and improve upon the prior erosion control materials and use professional experience and
successful contractor feedback from others in the field to improve the controls selected in designing erosion
control materials.
The following is a Check Sheet designed to aid a design engineer to walk through the City of Fort Collin’s
Requirement as well as common questions to try and self-answer before the submittal of erosion control
material to the City. Though this will not eliminate all comments or redlines on a project, using this sheet should
significantly reduce the number of comments and catch frequently seen issues from submitted materials.
Ver 2.0 – 04/2020
Submittal Check lists of Erosion Control Requirements
Please the following questions to determine what requirements are needed for erosion control review.
FCDCM Chapter 2 Section 6.1.1 and 6.1.2
1) Is this project part of Emergency work less than 1 acre of disturbance? Yes No N/A
If question 1 is a “yes”, stop and submit a simple email to erosionreview@fcgov.com stating that, “The proposed
Project A as designed does not require erosion control review as this is an emergency activity that is less than an
acre” and then stop further progression on the checklist. If “no”, continue to question 2.
2) Is this project >8,000 sq. ft.? Yes No N/A
3) Is this project steeper than 4:1 (14°) slope? Yes No N/A
4) Is the project closer than 75 ft. from sensitive area? Yes No N/A
5) Is this project required to pull a CDPHE General Stormwater Discharge permit
associated with Construction Activity? (Including any projects that are a result of a
larger common development)
Yes No N/A
If questions 2, 3, 4, and 5 in this section are all “no”, submit a simple email to erosionreview@fcgov.com stating that,
“The proposed Project A as designed does not require erosion control review based upon the design criteria
thresholds are well below a level that would require a review” and then stop further progression on the checklist. If
any of the questions 2, 3, 4, or 5 is a “yes”, continue to question 6.
6) Is this project > 10,000 sq. ft.? Yes No N/A
7) Is the project steeper than 3:1 (18°) slope? Yes No N/A
8) Is the project 50ft or closer to a sensitive area? Yes No N/A
If questions 6, 7, and 8 are all “no”, then clarification is needed to determine if a project requires a submittal of
erosion control materials in accordance with FCDCM Chapter 2 Section 6.1.2 and skip to question 12 to ensure
adequate information is provided. If question 6, 7, or 8 is a “yes” continue to question 9.
9) Is this project >43,560 sq. ft. (1 acre)? Yes No N/A
If question 5 or 9 is a “yes”, an erosion control report, plan, and escrow will be required of this project.
If question 6, 7, or 8 is a “yes” an erosion control plan and escrow will be required for this project.
Continue to question 10.
10) Is the project <3 acres? Yes No N/A
If question 10 is a “yes” the erosion control plan will need to contain a sequence chart as part of the submittal. If
question 10 is a “no” the erosion control plan will need to contain multiple sequence sheets as part of the submittal.
See FCDCM Ch2 Sec 6.1.3.2 for those requirements and continue to question 11.
11) Is the project > 5 acres? Yes No N/A
If question 11 is a “yes” the erosion control plan and report will need to include discussions about erosion control
phasing and methods to break the project down into phases see FCDCM Ch2 Sec 6.1.5 for those requirements and
move on to the next section. If “no” skip questions 12 – 18 and move on to the next section.
12) Is the project name included on the submittal? Yes No N/A
13) Is the overall site location included in the submittal? Yes No N/A
14) Is contact information included in the submittal? Yes No N/A

If no Erosion Control Report, Plan, or Escrow were supplied, why was it missing?
For projects in the formal Development Review Process, Erosion Control Materials may be submitted at any time
prior to FP in the Development Review Process for review and comments. Erosion Control Materials shall be
submitted no later than FP (FDP) in the formal construction Development Review Process to meet the Erosion
Control Criteria.
For projects, not in the formal Development Review Process, Erosion Control Materials may be submitted at any
time prior to the final acceptance or approval of a project.
For all projects, it is recommended that materials be provided at 75-100% design. Early submission is encouraged
as it allows comments to get resolved in earlier rounds of review and does not delay the approval process.
Any of these materials that are required and were not submitted or were submitted yet were incomplete enough
for an in-depth review comments, may be required to undergo additional rounds of review and may delay final
approvals.

Evaluation of Materials
Unique Conditions To evaluate
Prior Site Contamination
Are there known environmental issues or prior site contamination with the site
that will need to be mitigated for?
(Asbestos in the soil, superfund sites, beet tailings, old landfills, industrial area, old
gas station, old dry cleaners, or other legacy structures that could have produced
chemical contaminations)
Yes No N/A
If this is a “yes” please ensure this information is included in the erosion control report as this is an addition pollutant
source beyond the 16 standard pollutant sources. Please include how to control the contaminated soils and
appropriate methods to handle such materials, if no report is required please include a length page note stating how
to handle the materials. The areas of concern should also be marked on the plans to have a guess as to where they
are located within the disturbed area.
Demo Activities
Are the approximate areas to be exposed from the building and structure removal
easily identified on the plans?
Yes No N/A
Is the estimated length of interim time called out between demo work and site
grading?
Yes No N/A
Will the starting of construction really be immediate? (Asked because only about
5% of the projects start within a month of demo, in all reality and most can take 3-8
months before final approval and permitted construction can begin this is time that
exposed dirt areas are typically not looked after or managed by demo contractors)
Yes No N/A
Are temporary controls called out to be used in the interim to prevent run-off of
the exposed soil between demo and site work?
Yes No N/A
Will site access be limited to prevent vehicles from driving through the exposed
soils?
Yes No N/A
Will temporary seeding and mulching need to happen as the area is exposed for
months?
Yes No N/A
Will the materials remain on site for any length of time? Yes No N/A
Will the structures be fully mitigated for asbestos before any demolition begins? Yes No N/A
Will the materials remain on site for any length of time? Yes No N/A
Will the structures be fully mitigated for asbestos before any demolition begins? Yes No N/A
Will water be used to prevent dust to be suspended during demolition? Yes No N/A
High Ground Water
Does the plan call out for a liner in the concrete wash out? (if a mobile unit is not
being implemented) This liner is needed as there is a significant nexus between
ground water and wash water that could negatively impact and become a source of
contamination to the groundwater.
Yes No N/A
Is there anticipated trenching of subgrade in the high ground water area? This work
will typically encounter water and will need a plan to address the water in the
trench and usually require dewatering activities. (See dewatering for further
questions)
Yes No N/A
Are there areas that will require seeding that may have water inundate for a long
period of time? This might require planning for the optimum time to seed where
the ground water will not choke out the seed and/or selecting the appropriate seed
type that will be able to handle highly saturated ground that serves as a source to
promote seed growth.
Yes No N/A
If no dewatering is anticipated with a project with high water, are their notes about
how handle dewatering if high water is encountered?

source when pumped?
Yes No N/A
Will it be a small enough volume of water that it will not discharged off site? If not
able to contain to site, a State Dewatering permit will be needed.
Yes No N/A

enough power to divert flows the anticipated pumping distance?
Yes No N/A
Does the erosion control plan have a note explaining that a dewatering permit is
needed if water is to be discharged off site?
Yes No N/A
Has the dewatering permit already been applied for? (permit needs to be approved
before dewatering activities are to occur this can be a 45-day lead time at the State)
(Conditions of the dewatering activities should be kept with the erosion control
materials on site, there should also be some description of what frequency samples
are being taken and what the samples are being tested for)
Yes No N/A
Is the dewatering activity near a contaminated location? (if contaminated soils are
present, dewatering activities may require the pulling of a remediation permit)
(Conditions of those remediation activities should be kept with the erosion control
materials on site)
Yes No N/A
Is there a copy of the Dewatering permit? A copy should be placed with the erosion
control materials when that has been approved.
Yes No N/A
Run on Flows
Are the flows identified on the erosion control plans? Yes No N/A
Do those flows identify if they are concentrated of distributed surface flows? Yes No N/A
Do the plans identify how much water will inundate the site? Yes No N/A
How much area will be impacted by these flows? Yes No N/A
Will some, or all, of the work expect to continue if inundated? Yes No N/A
Are there additional structures or pumping activities that will be used and shown
on the plans to divert the flows from encountering the dirt on site, i.e. pump
around the disturbed area?
Yes No N/A
Are there means to control and treat the additional flow once it has encountered
the dirt on site?
Yes No N/A
Is there time delays built into the project due to weather constraints or when work
areas are inundated?
Yes No N/A
Are the stored materials and hazardous materials shown on the plans located away
from the run on flow?
Yes No N/A

upset condition?
Yes No N/A
Working in water way
Have a 404 Permit been issued by the Army Corps of Engineers? Yes No N/A
Have a 401 Water Quality Certification been pulled from the State? Yes No N/A
Have surface flows that would encounter construction soils (such as a bank repair
location, coffer dam installation, or stream crossing) been included in the project
design? If so, the water moving across a property by State definition is considered a
dewatering activity and would require a dewatering permit to be pulled
Yes No N/A
As anticipated surface flows encounter those construction soils, is there an
anticipated water volume that will interact with exposed soils planned for?
Yes No N/A
Ver 2.0 – 04/2020
Are controls selected based upon those volume? Yes No N/A
Will there be hard armoring along the bank for permanent stabilization? (i.e.
riprap)
Yes No N/A
Will there be areas that will have grass or vegetation for permanent stabilization? Yes No N/A
Will those vegetated areas be blanketed or hydro-mulched? Yes No N/A

slopes, run on flows, or concentrated flows?
Yes No N/A
Is the seeding a realistic expectation based upon river flows and the seasonal
constraints?
Yes No N/A
Are the activities going to be conducted in the wintertime to minimize flow contact
with dirt?
Yes No N/A
Will coffer dams be used? If so, is there a liner or impermeable layer to prevent
mixing flowing water from scouring out the coffer dam and making that material
become a pollutant source?
Yes No N/A
Will there be above or in river crossings? Is it adequately sized and armored to
prevent washing out and away of the pipes and materials? Is there a detail showing
how the crossing will be designed and sized? Is the crossing shown on the erosion
control Plan?
Yes No N/A
Ver 2.0 – 04/2020
Minor Amendment Specific Items
Key thing here is that these types of reviews build upon the designs of old plans that were approved prior. On
these projects, it is important to first identify if the proposed changes significantly alter the scope of work in a way
that may require additional Control Measures. Many times, these minor amendments are facades or elevation
changes and do not affect the erosion control or will not disturb enough new area to trigger erosion control
requirements. When the submitted materials for a minor amendment significantly change the area of disturbance,
location of site or the scope of work it may require a reevaluation of the materials and potentially trigger a full
review of the erosion control materials. It is also important to note that if the materials were approved under prior
stormwater criteria, the old project planning materials will need to be brought up and held to the current
standards which many times requires the applicant to (re)produce reports, plans, or escrow calculations (see those
requirements under the full review process) that meet our current standard.
1) Are all the existing site conditions clearly different than the proposed changes? Yes No N/A
2) If these amendments are of an older project, have those previous materials been
updated to fulfill current drainage criteria?
Yes No N/A
