Query
As a SUDS(strategy)- For hardscape areas of roadways & pathways we will be using porous asphalt. What can be the runoff coefficient for these pervious asphalt areas.
Solution
1. Using porous asphalt is not a SUDS strategy. However it will contribute to run off reduction. For claiming percolation through asphalt you need to submit a third party test report for considering percolation rate.
