the exist<strong>in</strong>g development; e.g. exist<strong>in</strong>g l<strong>and</strong>scaped areas adjacent to exist<strong>in</strong>g build<strong>in</strong>gs orpark<strong>in</strong>g may be excluded from the “greenfield,” or development area.Where l<strong>and</strong> is be<strong>in</strong>g subdivided <strong>for</strong> the purpose <strong>of</strong> residential lot development, theDeveloped Area <strong>in</strong>cludes the total upl<strong>and</strong> area <strong>of</strong> the lots, road layouts, stormwatersystems, etc. (exclusive <strong>of</strong> the open space lot as may be provided to meet therequirement). Where l<strong>and</strong> is be<strong>in</strong>g subdivided solely <strong>for</strong> the purpose <strong>of</strong> <strong>in</strong>dustrial orcommercial lot development, the Developed Area <strong>in</strong>cludes the total upl<strong>and</strong> area <strong>of</strong> theselots, road layouts, stormwater systems, etc., (aga<strong>in</strong>, exclusive <strong>of</strong> an open space lot).As an example, a large commercial build<strong>in</strong>g proposed on a ten acre parcel <strong>in</strong> a SignificantNatural Resource Area, which results <strong>in</strong> grad<strong>in</strong>g <strong>and</strong>/or clear<strong>in</strong>g <strong>of</strong> five (5) acres <strong>for</strong> thebuild<strong>in</strong>g, site drive, park<strong>in</strong>g, stormwater <strong>and</strong> septic facilities, l<strong>and</strong>scaped areas, etc.,should calculate the 1:2 development to open space requirement as 5 acres x 2 = 10 acresopen space.Redevelopment RequirementsUnder the 2009 RPP, redevelopment <strong>of</strong> exist<strong>in</strong>g developed properties does not require theprovision <strong>of</strong> open space. A redevelopment project’s expansion <strong>in</strong>to “greenfield,” orundisturbed sites is further encouraged <strong>in</strong> Economic Centers; open space is required onlyafter the greenfield expansion portion <strong>of</strong> a redevelopment project exceeds 50% <strong>of</strong> theexist<strong>in</strong>g developed area on a site (MPS OS1.3). For example, an exist<strong>in</strong>g developmentwith a development area <strong>of</strong> 1 acre may exp<strong>and</strong> to a total development area <strong>of</strong> 1.5 acreswith no open space required <strong>in</strong> Economic Centers. Outside <strong>of</strong> Economic Centers,greenfield development associated with a redevelopment project is expected to meet thesame open space requirements as any other greenfield, or new development.Previously Permitted DRIsIf a project, previously permitted through the DRI process <strong>and</strong> required to provide openspace, returns <strong>for</strong> additional DRI review (expansion or redevelopment), only the area <strong>of</strong>the expansion or new disturbance should be used to calculate any additional open spacerequirements. The Commission may allow <strong>for</strong> a credit <strong>for</strong> open space provided <strong>for</strong>projects permitted, constructed, <strong>and</strong> <strong>in</strong> compliance with the requirements <strong>of</strong> the 1996 RPP(65% <strong>of</strong> a project property <strong>for</strong> SNRA, <strong>and</strong> 50% <strong>of</strong> a property <strong>for</strong> projects outside <strong>of</strong>SNRA).<strong>Open</strong> <strong>Space</strong> Technical Bullet<strong>in</strong>, 94-001, as Amended 5/14/09 7
