Depaving can be a big help when managing stormwater. Many of our properties have paved areas that are hardly used! Every little bit we break away adds up to a big benefit for all of us.
When Is this Practice Used?
Where a paved area is unnecessary
Improves rainwater infiltration
allows rainwater to soak into the ground, rather than becoming stormwater runoff
for Portland's average rainfall of 36 inches per year, one square foot of pavement removed can prevent on average of 22 gallons of runoff year
Pavement's store heat, by removing them you can help reduce the "heat island effect"
How to implement
Identify utilities by calling #811 or http://call811.com/before-you-dig
Investigate the area to ensure that depaving will not have an negative impact to surrounding spaces
Calculate how much material will be removed and how the material will be reused or disposed of
Decide what tools you will use to break up the concrete
Take appropriate safety precautions (eye protection, ear protection, suitable clothing, etc)
Break up the pavement into pieces you can pick up
Amend the soil
Plant Native plants
