The latest version of the LEED template for this credit (v5.0) has a change regarding how the compliance is demonstrated when the projects are outside U.S. Now we have to demonstrate compliance via a local equivalent to the U.S. codes. Regarding the 100-year flood requirement, when we tick the requirement we have to demonstrate compliance using an "equivalent local regulatory agency" or a "professional hydrologist". However, once this requirement only applies to previously undeveloped land I don't know how we can demonstrate compliance if our site is previously developed. In these cases it should be enough that the site is previously developed, don't you agree?

Yes, there are two criteria in the flood plain requirement - previously undeveloped and lower than 5-feet above the 100-year flood plain. Though I see how this form is confusing. I would submit a question to GBCI through the contact us avenue to get specific guidance on this. Hopefully, that will also ping the appropriate parties to make a universal correction.

Hello, did you obtain a reply from GBCI confirming that when the site is previously developed, we don't need a professional hydrologist report for the 100-year flood requirement? Many thanks
