• Permeable Pavement

1. Allows Runoff to infiltrate surface

2. Water is filtered as it flows through porous material

3. Pollutants are adsorbed onto subsurface sediments

4. Allows water to slowly flow into groundwater

• Installation1. Rubber grid installed over

surface2. Soil medium placed in grid

cells3. Grass planted in soil medium

• Install Rain Garden• Install Impervious

Wall• Add wetland plants

• Basic Rain Garden Design1. Hole dug using backhoe2. Course soil medium is placed in hole to hold water

runoff3. Wetland plant species planted at surface4. Water joins groundwater and slowly joins creek at
