Sustainable neighborhood rating systems: An international comparison
Die Bewertungsmatrix
Water
• SLL PRQ: Locate where there is no wetlands
or water bodies, compensate for
impacts to those if the area is highly developed;
if not highly developed, only minimal
impacts are allowed.
• SLL PRQ: If located in a floodplain, use
only previously developed areas and follow
federal recommended standards for
floodplain development.
• SLL CR: Conserve all water bodies, wetlands
and a buffer around them (may substitute
habitat conservation). (1 point)
• Impervious surface change: there is less imper-
vious surface and major impaired or contaminated
areas would be improved (1,0); there is
no impervious surface change and minor contaminated
areas are improved (2,0); 10-50%
more impervious surface is created (3,0-4,0);
over 50% more impervious surface is created
(5,0-6,0). Weight: 2.0%
• Ground absorption of rainwater: will increase
and be cleaned by a filtering process (1,0);
will increase (2,0); does not change (3,0); will
decrease somewhat (4,0); will greatly decrease
(6,0). Weight: 7.0%.
• SLL CR: Restore predevelopment water
bodies or wetlands, in an area equal to
10% of the development footprint (may
substitute native habitat restoration). (1
point)
The nearby surface waters will be: improved
•
(1,0); not changed (2,0); impaired (4,0); significantly
impaired (6,0). Weight: 3.0%.
• SLL CR: Create a management plan and
funding for habitat sites or wetlands and
water bodies for 10 years (may substitute
native habitat site management). (1 point)
• GCT CR: Stormwater treatment should
infiltrate, reuse or evapotranspirate runoff
from 90% of average annual rainfall or 1
inch rainfall. Points awarded by percent of
impervious surface treated, with the lesser
number for previously developed sites: 15-
20% (1 point); 30-40% (2 points); 45-60%
(3 points); 60-80% (4 points); 75-100% (5
points)
