My jurisdiction's Master Plan calls for residential density to be calculated using the net density, rather than gross density, of a site or development. However, we have no formal policy of how to determine net density.
Typically, areas to be dedicated to parks or roads, or undevelopable areas such as wetlands, are removed from the net density calculations.
My question is quite simple. How do other communities calculate net residential density? Or, how should net residential density be calculated?
