If your site has been previously developed, you can skip the floodplain requirement. However, it’s still good practice to consider site development and design strategies to mitigate your project’s risk from flooding.
Document the status of your site, using information from whatever source you find most useful. You will not need to submit this documentation for LEED, but it’s worth having on file.
Not all farmland is considered “prime”—dry, western ranges, for example, are typically excluded. Even if a site is being farmed, check whether it is prime according to USDA definitions.
