. Alewife Reservation & Alewife Brook master plan. Wetlands; Wetland conservation. Area 5: Alewife Subway Station Existing Conditions and Key Challenges This section of the Alewife Reservation occurs within the 100-year floodplain and is classi- fied as wetland habitat. The Alewife Brook, which emerges from its buried pipe to join the Little River near the Alewife subway station, contributes contaminated stormwater runoff and combined sewer overflows. Portions of the Alewife Brook and Little River near the subway station have been armored to prevent further erosion from the storm runoff surges that occur in the area. Yates Pond is infested by both common reed and Japanese knotweed and is entirely surrounded by transportation infra- structure. Stormwater from the subway station parking garage drains to Yates Pond. The loca- tion of the subway station, Minuteman Bicycle Trail and nearby recreational fields in both Ar- lington and Cambridge make this area the most important access point to the MDC parklands. However, Yates Pond is not accessible by any marked trails. The only landscaped portion is. the small section where the Minuteman Trail passes through the Reservation along the Route 2 access road. A paved sidewalk runs along the edge of the subway station access road that overlooks Yates Pond, a former clay pit that is an important cultural resource in the area. Recommendations 1. Remove invasive species and establish native plantings. (Refer to Section 3F for specific management and mainte- nance recommendations.) Particular attention should be paid to areas along the road so that views of the pond are available year round. Establishing native plant communities, including herbaceous species, can also help to improve the ability of this area to treat stormwater from the Alewife subway station and thus improve water quality. 2. Provide access along Yates Pond with a boardwalk parallel to the sidewalk, pro- viding a safer connection to the Linear Path. 3. Instal
