Increased impervious surface increases runoff, decreases evapotranspiration, and decreases infiltration
Percentage of Impervious Surfaces

Stormwater: The Conveyance Approach
Stormwater conveyance is the rapid removal of stormwater from impervious surfaces to receiving streams by way of engineered
drainage systems (e.g. culverts, stormdrains, and channelized streams and rivers).
“water is a problem. Its the enemy. Get itaway from here.
NOW!”
![Page 10: Geography.hydrology](https://reader033.vdocuments.us/reader033/viewer/2022051609/545e932bb1af9f0e598b4892/html5/thumbnails/10.jpg)
Stormwater: The Infiltration ApproachInfiltration is the the retention of stormwater as close as possible to its originating source(s), and infiltrating as much as possible into the soil through the implementation of best management practices and strategies.
“water is a precious resource, keep it here, clean it, save it for later - we need it, and our local our ecosystems need it too!”

Guidelines:1. Start at the source2. Integrate the solutions3. Maximize permeability4. Minimize directly
connected impervious areas5. Use drainage as a designelement
