Designated Erosion Control Inspector Program (DECI)

2020 DECI Re-Listing is Now Open!

The 2020 Designated Erosion Control Inspector (DECI) re-listing is now available for online applications. We created a step-by-step tutorial on how to re-list. Please read the following instructions carefully before proceeding.

The deadline for the DECI re-listing is Nov. 30!

Disclaimer! The re-listing is done under a “License” module in our online system. Please note that DECIs are not licensed but the module is being used to facilitate the online re-listing process.


  1. All DECIs that want to keep their status active must re-list and pay their fee, regardless of the year they became a DECI (even if you became a DECI last week).
  2. Education requirements are based on the year you became a DECI (please see the tutorial for required hours).
  3. If you are a County employee, you cannot use your County email address to create an account online, please use a different email address.
  4. If you previously created a Citizen Self Service Portal Account, you do not need to create another one, just login with your previous credentials.
  5. Gather all your education documents and form of payment (credit card or e-check) before you start the process and have them ready to go through the entire process in one sitting.
  6. Do not use any education credits from before the previous re-listing which was in March 2017 (any education hours prior to that date will not count for this cycle).
  7. If you have to stop before completing the re-listing, do not start a new application, use the Dashboard to resume your previous session.

If you have any questions, please contact Mea Blauer at or (847) 377-7701.

On Tuesday, Oct. 13, the Lake County Board approved the revised version of the Watershed Development Ordinance, which includes an amendment to the DECI education requirements. 

The listing of the Designated Erosion Control Inspectors shall be officially updated every three (3) years by the SMC. Continuing education requirements shall be as follows:
1. Attendance at each annual DECI training seminars shall be sufficient for the three-year listing period. 

2. Alternatively, DECIs must attend twenty-four (24) hours of work-related professional development hours within the three-year period for relisting.  

What is a DECI? 

DECIs are trained and qualified soil erosion and sediment control inspectors. They improve communication and act as a liaison between an applicant/developer and enforcement officers (EO) for regulated development in Lake County. DECIs, who are the boots, eyes, and experience on the ground, are employed by the applicant and not the permitting agency. Only DECIs can inspect projects where the permitting agency requires one.
