Slide 54 of 87
Notes:
When using better site design tools, a watershed manager should be realistic about how much impervious cover can be reduced through better site design in a subwatershed. While better site designs can reduce the impacts of individual development projects, the cumulative impact of too much development can still degrade water resources, no matter how well each site is designed. The value of the site design tool appears to be greatest in those subwatersheds that are approaching their maximum impervious cover limit. Thus, a watershed manager needs to make some careful choices on how to best promote better site designs within a subwatershed.
