Hello LEED User ND forum,

I am preparing my Stage 1 LEED ND project for the SLL Prerequisite Review. In doing so, I noticed that Project Information From (PIF) 3 requires a map specifying the construction impact zone. This zone is described pretty clearly in the definitions in the LEED ND Reference Guide. However, I'm having trouble finding any specific ND requirements that refer back to the construction impact zone.

So, my questions are the following:

1. What, if any, are the requirements for the construction impact zone? Do these requirements go beyond 'stay out of any wetlands, water bodies, or areas with imperiled species and ecological communities'?

2. At this early stage in my project, I cannot know very precisely what the construction impact zone will be. Because this is a greenfield project and it involves a lot of landscape restoration and park development, the impact zone is likely to go a far beyond the development footprint. The safest assumption, although clearly an overestimation, is that nearly everywhere will at some point be subject to some work, even if that is just digging and planting. Is there any reason to think this would be a problem with regards to LEED ND, so long as areas protected by LEED ND prerequisites are kept out of the impact zone and no work happens within them?

Thanks again,

Daniel
