− | These include intermittent and ephemeral channels. Buffers provide filtration, infiltration, flood management, and bank stability benefits. Unlike stormwater ponds and other structural infrastructure, buffers are essentially a no capital cost and low maintenance form of infrastructure. In general, the literature recommends stream buffers for pollutant removal and support of aquatic and terrestrial riparian habitat <ref>Wenger, S.

The benefits of buffers diminish when slopes are greater than 25%; steep slopes should not be counted as buffer <ref>Scheuleer, T (1995) The Architecture of Urban Stream Buffers.
