Alewife Brook and the Little River are anadromous fish runs. The herring runs have been a major event in the Alewife Reservation area. However, over the past few years, the herring have declined. The Little River has become increasingly shallow and local advocates speculate that the river may be less suitable for herring as a result of stormwater runoff and associated deposition.
The history of the Little River and the associated emergent marshes is typical of urban wetland marshes. However, recent changes in land development patterns and unique opportunities to reverse the historic degradation make this area a prime candidate for the Priority List for Coastal Wetland Restoration program.
Based on an old Sanborn map, it appears that the Little River originally ran through the Central Wetland until the river was relocated to its current location as a result of state-sponsored dredging and widening in the early/mid 1900s. The riverbanks are straight and fairly steep, and until recently, have been largely lined with office buildings.
As a result of recent zoning changes addressing the redevelopment of Acorn Park, many office buildings, as well as a large parking area adjacent to the river and associated wetlands, will be removed over the course of the next 10 years, and the areas returned to a natural state. In addition, the MA Department of Conservation and Recreation (DCR) recently completed a comprehensive Master Plan for the urban wilds of the Alewife Reservation. Locally, a major tri-community effort (Arlington, Belmont, and Cambridge) is in place for finding solutions to the flooding at Alewife. The support of BHX will further foster the collaboration between the three communities and result in measurable improvements to the Little River and Alewife Brook.
The City of Cambridge has proposed a stormwater management basin designed to treat stormwater and improve water quality in the watershed area by upwards of 90 percent. This design is now moving forward through the permitting process. Finally, the Federal Emergency Management Agency (FEMA) is in the process of calculating and updating the 100-year storm event in the area.
Natural Resource Conditions
A large emergent marsh is located on private property, owned by BHX, an affiliate of Bulfinch Companies. This wetland has been called the Central Wetland due to its central location and is approximately 10 acres in area. As such it is the largest wetland area in Cambridge and possibly, in the region. It is now largely stagnant and supports a monoculture of invasive species, including Phragmites and Purple Loosestrife. Historically, even as late as the early 1900’s, this area was a diverse emergent marsh with an unrestricted flow to Boston Harbor, providing food, cover, and breeding habitat to a diverse wildlife community, including anadromous fish. The current Phragmites reed marsh contains vernal pool areas, and has the potential to regain some wildlife diversity, and, in conjunction with protected upland habitat, creating a unique breeding and foraging habitat for the species that have started to repopulate the reservation.
The Central Wetland receives stormwater drainage from Route 2 and from a pipe connecting the wetland to land in Arlington, located to the north of Route 2. The current stagnant conditions have resulted in a general degradation of ecological conditions. One goal of restoration is to improve the hydrologic pulsing to this wetland to encourage a more diverse ecological community and to create a more efficient flood plain for consistent flow to Little River. Other restoration options are being discussed in an effort to manage the invasives, improve stormwater quality, address flooding issues, and improving the quality of the Little River to restore anadromous fish runs.
Overall Restoration Goal
There are several wetland restoration options that will contribute to the local, state, and private restoration efforts. Restoration efforts can include riverbank restoration, emergent marsh restoration, and restoration of wetland wildlife habitat.
A restored wetland of approximately 10 acres will have a positive effect on the entire Alewife Reservation and downstream communities. The restoration of the Central Wetland would work in conjunction with the DCR Master Plan initiatives and the City of Cambridge’s stormwater management improvement plan. By ameliorating upstream conditions at the reed marsh, and improving riparian drainage, an offshoot of the restoration via removal of invasive species, a significant improvement to the ecological conditions of the entire watershed can be expected. The upstream town of Belmont also plans to improve its water quality drainage in the next year, further contributing to the restoration activities.
The following data is currently available for use in restoration planning and design: the wetlands have been flagged and approved by the Cambridge Conservation Commission, some topography is available in the buffer zone to the wetlands and along the banks of the Little River, the stormwater drainage system has been studied and evaluated in terms of pipe sizes, slopes, and inverts, and a preliminary assessment of wetland functions has been conducted. In addition, preliminary research into Phragmites management has been initiated with respect to improving on the stagnant conditions by increasing flow into the wetland.
Development of a better understanding of the 10-acre wetland through restoration planning and design will aid in these efforts. As the entire Little River falls within the 100-year floodplain, a key issue that must be addressed in the restoration of the central wetland is to ensure that floodwaters are not backed up through the pipe(s) beneath Route 2 to exacerbate flooding in Arlington.
Support Requested of the CWRP
There are several areas in which the CWRP could assist in this collaborative effort. Some ideas are listed below, in no order, and are not comprehensive or meant to be limiting:
· Hydrologic analysis of Central Wetland, including evaluation of redirecting flows through wetland
· Invasive species management
· Sediment testing to evaluate dredging potential
· Topographic survey of Central Wetland
· Community education and training
· Wildlife management implementation
· Construction of improved storm drainage structures or new drainage structures
