Hi all, Regarding NPD P3, Is it necessary for achieving this prerequisite to include the green open space area into the net area used to calculate the intersections per sp. mi? (equation 1, Intersections per sq. mi. = total intersections/net area) Thank you

Angelica, como estas? The calculation of square mileage excludes, among other things, only parks larger than 1/2 acres, slopes over 15%, and areas nonbuildable under law. If the local code does not specify open space allocation then it is assumed all is buildable and cant be excluded from the net area. Saludos, Gonzalo

Gonzalo is essentially correct, but the exclusion for codified non-buildable areas can be for any purpose, not just open space. The full list of exclusions includes: water bodies, parks over 1/2-acre, public facility campuses (eg schools, hospitals), airports, railyards, slopes over 15%, and areas non-buildable under codified law or the rating system. So if a local code prohibits construction for any reason on land within the connectivity-shed, then it’s excludable.
