1 to 3 points (1 to 2 Healthcare); applies to all eight BD+C adaptations. Retain on site, through low-impact development and green infrastructure (infiltration, evapotranspiration or capture and reuse), the runoff from the 80th, 85th or 90th percentile rainfall event (70th, 75th, 80th for zero lot line projects); or retain the increase in runoff over the site's natural land cover condition for the full points.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
