− | 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 (Wenger, 1999). The benefits of buffers diminish when slopes are greater than 25%; therefore steep slopes should not be counted as buffer (Schueler, 1995). | + | These include intermittent and ephemeral channels.
