(#7782) Runoff coefficient for grass pavers


What should be the runoff coefficient in case of grass pavers? Should it be taken the same as turf or brick paving? Also, area to be considered for the grass pavers is equal to the total grass paving area or does it have to be separately considered as vegetated area?
Request you to please clarify.


The run-off coefficient for grass pavers is considered based on the percentage of grass area in the paver block. Run-off coefficient of turf should be considered for the percentage of paver block that contains grass while run-off coefficient of concrete/kota paving should be considered for the remaining void area.
