To assist with initial site assessment, a brownfield runoff tool with printable reporting for the chosen rainfall events would be useful in the Preliminary sizing ribbon to allow analysis of brownfield and greenfield runoff rates from the same location. This tool is already implemented by competitors such as Causeway and is a very helpful feature.

I totally agree, having a calculator where you can perform these napkin calcs from the outset could be helpful. I will move the status of this to "Gathering Support" and will engage in consultations with a wider array of stakeholders to gauge their interest and gather additional perspectives on the proposed feature.
Should we observe a substantial level of enthusiasm and demand from our customers, we will be inclined to advance the status of this suggestion to "Under Consideration."
This stage will involve a more detailed analysis, including a feasibility study, resource allocation assessment, and preliminary planning to understand how this feature could be seamlessly integrated into InfoDrainage.
Thank you for the suggestion and thanks to those who voted.
The brownfield runoff calculator already exists within the design wizard report, users can add an impermeable area, run a wizard and it will give them the brownfield runoff under Flow attribute - there is more flexibility here to switch between the Rational Method, Modified Rational Method and a French method called (Methode de Caquot).
