Manage stormwater with 'sheet flows'
Disperse water runoff gently
To reduce downstream flooding and keep pollutants out of local waterways, try not to direct stormwater into concentrated channels. It's better to design the edges of impermeable areas so water can disperse broadly, known as a sheet flow. Water can be directed into infiltration basins, vegetated swales, or vegetated filter strips. The idea is not to send streams of runoff across vegetated areas.
