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?

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.

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.

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?

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
