NC-v4 SSc4: Rainwater management

Path 3 states: "manage on site the runoff from the developed site for the 85th percentile ". I guess this requirement was made to exclude the sidewalk from calculations. Am I reading this correctly?

Hi Gustavo,
You will need to manage the runoff from all areas within the LEED project boundary. If the sidewalk is within the project boundary, it needs to be included.

I am working on a project that consists of two office buildings which are tight to the sight boundary but there is some open space between the two buildings. I presume this can't be considered as zero lot line ? For zero lot projects does the buildings need to be tight to the property line. ?

the v4.1 BD+C reference guide defines 'zero lot line' as building footprints that cover 90% or more of the site.

Just one further question. How do you calculate your building footprint when you have 2 levels below grade. For example the basem*nt might take up the whole site but the ground floor footprint will be smaller ? Is there any guidance on this ?

footprint of ground floor should be used.

David,
It looks like thezero lot line definition is removed in the October 2021 version of the reference guide. Has anything changed?

Not to my knowledge.
