Erosion and sediment control report and drawings: Submission requirements

Project sites with an area equal to, or greater than, 0.4 hectares (ha) will require the submission of an Erosion Sediment Control (ESC) Plan. The ESC Plan must consist of an application, drawings, and supporting documents. These documents are meant to provide a comprehensive plan for ESC implementation, inspection, and maintenance practitioner(s) to follow during construction.

Project sites with an area less than 0.4 ha, and where there are no site characteristics that indicate greater than normal ESC concerns, must adhere to Specifications as outlined in the Development Permit (ESC Good housekeeping practices). These sites do not generally require submission of an ESC plan. The City reserves the right to request an ESC Plan on any site that is less than 0.4 ha if it is believed there is potential of an adverse effect to property, infrastructure, health, safety or the environment.

Here you will find information on the requirements, specifications and tools as well as the application process for submitting Erosion and Sediment Control Plans to The City as a part of construction and development projects.

  • Application:
    • The application is a fillable pdf form that is required for all ESC Plans. Filling the application out will inform the drawings that will be required for your Plan. Note: For best functionality of this application, it's recommended that the form be downloaded to a computer and opened with Adobe Acrobat Reader.
  • Application Instructions:
    • The application instructions provide a detailed explanation of what is required for each section and sub-section of the Application.
  • Specifications:
    • Specifications define the general ESC requirements and design, installation, maintenance and removal for standard ESC practices.
  • ESC Guidelines:
    • The guidelines provide an introduction to ESC principles, regulatory requirements, ESC Plan design requirements and considerations.

Temporary digital submissions:

To help limit the spread of COVID-19, you will temporarily able to submit ESC applications digitally, and/or via hard copy delivery.

Digital submissions can be sent to ESC@calgary.ca or your respective reviewer. Please note the following:

  1. This is a temporary service and will be discontinued when we return to normal operations.
  2. We are working towards developing a permanent process for digital submissions, but are not there yet. We will keep you posted on progress for digital submissions in the future.
  3. All submissions will require a FINAL physical copy for our official records. We will arrange this with you once we return to normal operations.

Hardcopy delivery:

Shipping and receiving will continue to accept submissions; however it may take a couple attempts for someone to open the door. Please contact Denise Nogueira at 403-554-3167 if you are unable to deliver your submission.

Please note: you may experience a delay in receiving an email confirmation of your application and the expected review date. Contact Denise Nogueira at 403-554-3167 if you have not heard from us within five business days.

This delay will not impact your review timeline. All submissions will be addressed on a first-come first-serve basis and we are still working within our expected 14-business day review timelines.

Request a reduction in winter inspection frequency before November 30

Your site must meet the following requirements:

  1. There will be little, to no activity, on site throughout winter.
  2. Your site matches an approved ESC drawing.
  3. There is no evidence of non-compliance (dirt ramp, release, socks and donuts, missing mandatory cover).

To apply:

  1. Implement your winterization plan onsite (Section 6 of your ESC plan).
  2. Download and fill out the ESC Winter Inspections Frequency Reduction Request form.
  3. Submit your last three ESC inspection reports along with the request form.

Frequently Asked Questions

LS3 Calculator

To make calculating LS values for your site more streamlined and consistent, The City has created a LS3 Calculator. This calculator uses the LS3 table from Agriculture and Agri-Food Canada’s RUSLEFAC Revised Universal Soil Loss Equation for Application in Canada (2002) to determine an LS value from a given slope grade (%) and length (meters). The LS3 table was used as it is the Topographic Factor table that is recommended by Agriculture and Agri-Food Canada for use on construction projects that have a high ratio of rill: inter-rill erosion.
