OverviewA major focus of the Buzzards Bay NEP remains the protection and restoration of coastal and inland wetlands and habitat in the Buzzards Bay watershed. In the map below of core wetlands, it is clear how important wetlands are in the Buzzards Bay watershed.
The interactive map files below show DEP core wetlands evident from aerial photographs, at a much higher resolution than the map at the top of this page. Actual jurisdictional wetland areas generally exceed the aerial mapped wetland areas, but these maps are very useful for planning, evaluating wetlands on undeveloped parcels, and for documenting legal and illegal wetland destruction. These files are quite large so we recommend downloading them to a specific directory on your computer (right click on the link, then save to a new directory e.g. "googleearth"), then opening them with Google Earth.
If you do not have Google earth downloaded on your computer, we recommend you install this free program is you want to use some of the geographic data sets we provide on our site.

BackgroundMarine and freshwater wetlands are some of the world's most naturally productive areas, and they perform many functions that are useful to man. The Massachusetts Wetlands Protection Act, Massachusetts G.L. Chapter 131, section 40, officially recognizes that wetlands are crucial to the following interests:
- Protection of public and private water supply
- Protection of groundwater supply
- Flood control
- Prevention of storm damage
- Prevention of pollution
- Protection of land containing shellfish
- Protection of fisheries
- Protection of wildlife habitat.
In Massachusetts, 4050% of the wetlands base has been lost, and wetlands continue to be destroyed and degraded at an unacceptable rate. A recent study conducted in the southeastern part of the state indicated that between 1977 and 1986 alone, over 1300 acres of freshwater wetlands were lost. Although the passage of the inland wetland protection regulations in 1983 improved this situation considerably, these wetlands are still being lost, and the current regulations for freshwater wetlands fall short of full protection.
Massachusetts provides a higher level of protection for its coastal salt marshes through the Wetlands Protection Act Regulations and the Wetlands Restriction Program. The regulations are less protective of subtidal wetlands and habitat. Although the Wetlands Protection Act offers some protection for these areas, they nonetheless are being altered by increased in boat activity, and declines in water quality from nonpoint source pollution and nitrogen loading. Bordering vegetated wetlands are provided an intermediate level of protection, but state rules for "limited projects" allow for up to 5,000 square feet of wetlands to be altered or filled for a number of reasons. State and federal regulations offer virtually no protection to isolated wetlands.
In general, cumulative impacts from many small projects are a major threat to all types of wetlands and are often the most significant cause of wetland degradation and habitat decline. This is because the existing management framework for wetland protection is inadequate for assessing and protecting against cumulative impacts.
An important part of the problem in protecting wetlands is that some Conservation Commissions may not be using existing state regulations as effectively as possible to protect wetlands and marine habitat. The present regulatory process seems to be inadequate to deal with the growth that is fueling the continuous loss of wetlands. Because the Wetlands Protection Act provides what many consider only a statewide minimum level of protection, many communities have adopted zoning or non-zoning bylaws to further protect the interests of the Massachusetts Wetlands Protection Act. Sometimes these local measures add additional wetland resource values of sedimentation control, recreation, agricultural and historical values, aesthetics, and aquaculture. These local efforts provided an enhanced layer of regulatory oversight and protection to wetland resources.
Wetland Protection StrategyIn the 1992 Buzzards Bay CCMP Wetlands Action Plan, the Buzzards Bay NEP identified as its principal goal of the "Long-term increase of high-quality wetlands and coastal habitat in Buzzards Bay." This concept was well ahead of its time, because the federal government and Commonwealth were just beginning to embrace a "No Net Loss" policy. This goal also flew in the face of the reality that at least 40% of Massachusetts' original wetlands had already been lost.
In order to achieve the CCMPs goal, the following objectives have to be achieved. We must:
- Protect existing wetlands.
- Encourage restoration of wetlands (and allow replication as a last resort).
- Improve enforcement of wetlands laws.
- Upgrade the capability of local conservation commissions.
- Encourage non-permitting options as a supplement to the issuance of permits whenever possible.
- Protect and restore habitat used by threatened, rare and endangered coastal species and anadromous and catadromous fish.
Buzzards Bay municipalities often request technical support from the Buzzards Bay NEP for a wide range of wetland issues to achieve these objectives including review of wetlands delineations, review of permits and engineering designs, preparation of local bylaws, training on wetland boundary identification, and local decision making procedures. We also have provided grants to towns for a wide range of projects.
In the sections below are some resources that can help municipalities and citizens protect and restore wetlands.
An important focus of the BBNEP has also been to encourage the adoption of local wetland buffer regulations. A good general reference on the importance of wetland buffers, and regulatory language that can be used as the basis of local regulations can be found in the document Planner's Guide to Wetland Buffers for Local Governments (677 kb pdf) by the Environmental Law Institute.

Falmouth Wetland Regulations.
In Massachusetts, implementation of the state wetland regulations is delegated to municipal Conservation Commissions. These Conservation Commissions, generally made up of 5 or 7 volunteer members, are appointed by Town Boards of Selectmen or City Councils. Under Massachusetts Home Rule legislation, municipalities may also adopt local bylaws that are more stringent or better reflect local needs than regulations under the state's Wetlands Protection Act. Most Buzzards Bay municipalities have adopted these local bylaws. On this page you will find new revised wetland regulations that the Town of Falmouth is about to adopt. In 1987, the Town of Falmouth adopted through Town Meeting its current wetland bylaw and regulations. In 1997, the Buzzards Bay NEP is helping the town rewrite these regulations to bring them up to date and to be more consistent with the State's Wetland Protection Act regulations."
Falmouth Black Beach and Sippewisset DCPC Regulations.
On Cape Cod Massachusetts, a county government body known as the Cape Cod Commission has established a process where towns on Cape Cod can designate so-called "Districts of Critical Planning Concern" ("DCPCs"). Such a designation enables better protection of living resources, habitat, water quality or other interests identified in a DCPC designation. In DCPCs, the Cape Cod Commission would provide an additional level of regulatory oversight on development and other activities within the DCPC boundary. For a DCPC designation to be accepted by the Cape Cod Commission, towns must adopt local regulations applying to the DCPC.
In the Town of Falmouth, the Falmouth Conservation Commission developed these regulations for an area known as Black Beach and Sippewisset Marsh with technical and administrative support from the Buzzards Bay NEP. The Project worked with the town to ensure that these DCPC regulations with Commonwealth of Massachusetts Conservation Commission authorities and met the technical requirements of the DCPC regulation. The page above is the complete DCPC regulations that the Town of Falmouth adopted. These regulations are enforceable both under the Town's local wetland bylaws and the County's DCPC regulatory oversight.

Two Early Landmark Wetland Interventions by the Buzzards Bay NEPPage about the BBNEP's involvement in the Acushnet Conservation Commission abandoning a town wetland form
This correspondence on the page above is notable because in 1992, Acushnet was one of several Commonwealth communities that created their own wetland permit form and application process. The Buzzards Bay NEP felt that the town's application process did not provide adequate public notice, due process, or state review. In 1992, the town of Acushnet filed only 3 wetland permits with DEP, whereas 200 "in-house" wetland permits were issued without review. As a result of this letter, and an appeal by the Buzzards Bay NEP of a town-accepted wetland boundary in a particular case, the Town of Acushnet abandoned their in-house wetland permit application form by the following year. The town also later agreed to hire a Conservation agent as part of a tri-town district with Marion and Rochester.
The Mattapoisett Holly Woods Road Subdivision Case page
This letter (the first of nine pieces of correspondence by the Buzzards Bay NEP), and a wetlands appeal by the Buzzards Bay NEP, eventually led to a series of actions that resulted in a developer of a residential subdivision agreeing to re-delineate the wetlands on a 90+ acre subdivision. It turned out that 60+ acres of wetland were overlooked in the original wetland permit filing with the Town of Mattapoisett, and under an agreement with DEP, fill was removed from wetlands.
