..when you build a thing you cannot merely build that thing in isolation, but must also repair the g pworld around it, and within it, so that the larger world at that one place becomes more coherent, and more whole; and the thing which you make

Stormwater BasicsStormwater Basics
• Construction always impacts water runoffConstruction always impacts water runoff• Impervious surfaces (roofs, patios, drives, roads) collect pollutants and speed runoffroads) collect pollutants and speed runoff
• State regulations protect watersheds from ll i i d fl dipollution, erosion and flooding
• PMEV located in University Lake, Jordan Lake and Cape Fear River watersheds
Stormwater Design ConsiderationsStormwater Design Considerations
• Buffer needed on both sides of streams
• Minimize impervious surfacesMinimize impervious surfaces• NCDENR currently does not make allowance for imperviousmake allowance for impervious pavements or green roofs
