Hello, I am making the map of our anticpated construction impact zone, and I am wondering about development that is taking place outside of our LEED Boundary. My project is a small development that takes up about 2 city blocks, and will be surrounded by roads that are being built as a separate project (they are outside of the LEED ND Boundary). I have included these features on our maps before in order to give USGBC a sense of what the end development will look like, but am not counting them as part of the LEED ND zone. In calculating the construction impact zone, do I need to take these additional improvements into account? Or can I extend the impact zone from around my buildings as per the construction documents, and count the land impacted by the Non-LEED portion as a separate project.

Sam, the ND definition of 'construction impact zone' includes the project's development footprint (i.e. all impervious surfaces), "plus areas around the improvements" impacted by project construction, so it's conceivable that your impact zone could extend beyond the project boundary in cases where a project improvement is close to the boundary. On the other hand, you don't need to account for the external street improvements since they're outside your boundary to begin with and aren't part of your project. Eliot

Eliot, I think that since we're drawing the project boudnary close to the buildings, I will call the impact zone the boundary plus a buffer around the buildings that has been called out in the construction documents. Thanks for your advice. Sam
