You may need to set up a temporary irrigation system for a vegetation establishment period of up to one year (going beyond one year would conflict with the intent of this credit, and WEc1: Water Efficient Landscaping). The system should be designed for easy removal.

Case 2: Previously Developed Sites

Any project with vegetated landscaping, including exterior planter boxes, must establish a plan for minimizing the use of chemical fertilizers. Strategies include:

landscaping with native or adapted plants,
using organic or natural fertilizers,
fertilizing based on need, rather than on a pre-determined schedule,
and maintaining soil health to limit the need for chemical fertilizers.

Installing signage to educate users about the value of protected land helps ensure that natural areas remain respected and protected. 

Work with the management team to ensure that continued protection protocols are put in place for the buffered areas, to help preserve them and the natural areas beyond. 

Case 1: Greenfield Sites

Provide the total site area restored or protected, total site area (including the building footprint), the building footprint, a site plan showing all natural areas contributing to credit compliance and, if you are providing full documentation (not attempting the streamlined LPE path), a list of the native and adapted vegetation that contributes to credit compliance. If you are providing documentation through the streamlined LPE path, a Registered Landscape Architect needs to sign off stating that the requirements for native or adapted plantings have been achieved. 

Upload documentation to LEED Online after construction activities have ended.
