Green Area Ratio Overview

GAR overview

What is GAR?

The Green Area Ratio is an environmental sustainability zoning regulation that sets standards for landscape and site design to help reduce stormwater runoff, improve air quality, and keep the city cooler.

GAR Checklists May Now be Signed Electronically

Online approval of the GAR Landscape Checklist is now available through the DOEE Surface and Groundwater System. Certified Landscape Experts (CLEs) should coordinate with the DOEE inspector for their project to verify if they will attend the final inspection, or if the CLE will have a representative at the construction site. CLEs should follow the instructions below to receive final GAR construction approval as expediently as possible.

  1. Before the CLE can sign the GAR Checklist statements, they must create a DOEE Surface and Groundwater System account if they do not have one already. The CLE must go to the through the DOEE Surface and Groundwater System to create an account. The email entered in the CLE information section of the project must match the email associated with the CLE’s account. Creating an account does not automatically grant the CLE access to projects they are working on in the system (see Step 2).
  2. Before signing the checklist statement, the CLE must have their contact information and licensing credentials which meet GAR requirements entered in the DOEE Surface and Groundwater System. Only the project owner/agent and those granted access may make changes to a project. Either the CLE must request access to the project from the owner/agent, or the owner/agent may make the changes for the CLE.

     a. During plan review, the project owner/agent enters the CLE information in the associated table. If the construction CLE is unknown at the time, then the design CLE's information will automatically populate the construction section. A database error will appear during plan review if the credentials are not provided.

     b. If the project was approved prior to May 5, 2020, then the CLE's credential information must be entered in the database before signing the GAR checklist. On the project page, click the "Add/edit CLE information" button to add the required information before signing the GAR Checklist.
  3. When DOEE's inspector completes the final GAR inspection, the CLE will receive an email requesting their signature on the landscape checklist. The CLE will click the link in the email and enter their login credentials.
  4. On the page that opens, click the “Edit” button at the top of the page, then complete all required questions on the landscape checklist. The database will automatically fill the credential information into the GAR Checklist. When the form is saved the CLE's electronic signature will be applied.
  5. Once the CLE saves the form the DOEE inspector will then sign the landscape checklist. After this is done the CLE will receive a completed copy of the GAR Landscape Checklist via email.
