This credit is particularly achievable for projects without wetlands or water bodies present onsite. If your project is locating on previously developed land, Option 1 is straightforward to pursue. 

The requirements get more complex if your project pursues Option 2. Under this option, you’ll need to avoid developing on various sensitive land types as outlined in the credit requirements. However, teams may make some improvements within wetland and water body buffers in order to enhance appreciation and enjoyment by all building users. The credit language includes a list of improvements that are considered minor and acceptable.

What’s New in LEED v4

• USGBC revised the floodplain limitations and now references the “flood hazard area shown on a legally adopted flood hazard map,” rather than the 100-year floodplain. Instead of being at 5 feet or more above the 100-year floodplain, you must now avoid the flood hazard area.
• The required buffer zone around a body of water has increased from 50 feet (15 m) to 100 feet (30 m).
• The wetland buffer has been reduced from 100 feet (30 m) to 50 feet (15 m).
• The requirements for sensitive habitat have been expanded to include species and ecological communities classified by NatureServe, local wildlife agencies, and their equivalents for projects outside the U.S. or outside of areas with NatureServe data.
• The credit now includes a list of permitted minor improvements in wetlands and buffer zones around bodies of water.
