SHRUB SPECIES SUITED TOR VARYING MOISTURE CONDITIONS &m0®t MANUFACTURED PERMEABLE SOIL PERFORATED PVC PIPE GRAVEL LAYER WRAPPED IN FILTER FABRIC FIGURE 25. Typical bioretention basin for stormwater infiltration and water quality treatment. 4. Realign the stream channel and alter cross sections to achieve a more bal- anced sediment transport regime. 5. Decrease sedimentation in streams and ponds by stabilizing eroded banks with bioengineering techniques. 6. Improve water quality by enhancing buffer areas, especially using native herbaceous plant communities on stream banks and pond edges. 7. Incorporate innovative stormwa- ter management techniques such as biofiltration basins and stormwater wetlands to improve water quality and decrease water quantity entering the stream system during storm events. These actions must be combined with similar efforts in the entire watershed if a measurable improvement is de- sired. 8. Achieve a water quality of Class B or better within the Alewife watershed to expand the possible uses of the water bodies to fishing and contact recre- ation. This effort requires regional planning efforts that focus on the entire watershed (see Section 4B, Rec- ommendations Beyond Study Area). Currently the Little River and Alewife Brook are classified as Class B (swim- mable, fishable) streams, but the cur- rent water quality does not fulfill the parameters set for a Class B stream and the official process for downgrading the status to the subcategory Class B, CSO is currently underway. C3. Habitat Restoration and Enhancement Despite the currently impaired habitat qual- ity, a variety of wildlife is commonly found in the project area and has been identified in recent studies and through observations. However, the remaining habitats are in need of protection and improvements to strengthen
