4        Environmental Inventory and Analysis

4.1       Geology, Soils and Topography

4.1.1      Soils and Topography - Description

Soils in Westborough are varied, although concentrated in three categories.  A good description is found in the "Report on Facilities Planning for Wastewater Collection and Treatment" (1981):

Wet soils are found in the lowlands and wetlands of central Westborough.  The hilly lands of the south and north consist mainly of glacial till where ledge and numerous boulders are common and drainage is well established.  The sandy loam found in these areas was cultivated into numerous apple orchards of Westborough.

According to the US Department of Agriculture "Soil Survey of Worcester County, Massachusetts," Westborough is comprised chiefly of the following soil groups: Merrimac fine sandy loam and Merrimac gravelly sandy loam, Gloucester stony fine sandy loam and stony loam, and Hinckley gravelly sandy loam.  There are also two areas, one at the extreme eastern corner and one at the extreme western boundary line of Westborough that are comprised of rough, stony land.

The topography of Westborough varies from hilly, irregular land in the southern and northeastern sections, to broad flat lowlands in the central and northwestern areas.  Fay Mountain, located in the southern part of the town, is the highest elevation at a peak of 707 feet above mean sea level.  The lowland plains and swamps are at an elevation below 300 feet.

4.1.2      Soils and Topography Impacts on Recreational Opportunities and Development. 

The enclosed map entitled "Special Landscape Features Map - Soils and Topography," highlights the general areas with very poorly drained bog and mineral soils.  It also shows the nonbuildable slopes of 25% and greater, generally avoided by developers.  These poorly draining soils are located in the natural drainage systems of Cedar Swamp, Crane Swamp, the headwaters of the Assabet River, and the SuAsCo flood control project.  The typical gentle slope of the areas are conducive to active recreation, but poor drainage typically prohibits active use.  However, there are opportunities for passive recreation on these soils. 

Topographic features are significant for open space preservation as potential conservation areas and sites for scenic vistas.  Approximately 10% of the town has a slope of 8% or greater.  Presently, most of the areas with steep slopes are forested or are poorly vegetated. 

Removal of vegetation and intensive development on steep slopes will change the "runoff" characteristics of these areas and should be avoided.  The loss of vegetation and of water infiltration into the soil will cause water to concentrate quickly,  resulting in more water reaching the lower elevations at a faster rate.  The streams in these areas will reach peak capacity much faster, and flood conditions will be more frequent.  The retention of vegetation on these critical areas will retard runoff that in turn will decelerate erosion and hold flood peaks at acceptable levels.

Peak elevations also provide the potential recreational asset of scenic views.  These sites will be discussed in the Scenic Resources and Unique Environments section.

4.2      Landscape Character

Historically, Westborough's landscape character consisted of farmlands carved out of the rolling, forested hills with broad expanses of gently sloping wetland area.  Most farming activities have been abandoned with the landscape reverting to old field and secondary forest.  Recently, many of these former agricultural sites have been converted into housing subdivisions.  The most prominent upland feature in town is Fay Mountain, located off Adams Street.  It served as both a directional landmark and observation point for early travelers.  Today, it continues to be a dominant landmark in the landscape and a spectacular town-wide vista and observation site and is being encroached by development.  These large scale landscape features are best viewed at a distance or from the peaks of the hills.  However, it is the smaller scale landscape features which have historically given Westborough its small-town charm:  lazy winding roads, such as Chestnut Street and Mill Road, lined by majestic oaks that meet over the center of the street; the gently rolling fields of raspberry canes, strawberry vines, and pumpkins of Nourse farm or the grazing Belted Gallaways of Glenrock Farm; the acres of apple trees of Arnold’s Orchards; the antique homes and European Beech trees lining West Main Street from the rotary to the rolling greens of the Westborough Country Club; the Country Store, horse pens, giant cow statue, and old orchards that once lined Adams Street; the woods and ancient stone walls lining parts of Ruggles Street and Gilmore Road; the brilliant flower displays outside of Wilkinson’s garden store; the unbroken rows of trees lining the shores of Sandra Pond, Lake Chauncy, and Mill Pond; and Uhlman’s Ice Cream stand on an August day.  These are the everyday images which best describe the character of Westborough.  They are also in danger of disappearing entirely as housing subdivisions, office parks, and shopping malls start to make Westborough look like any other cross section of suburbia.

Lake Chauncy, the SuAsCo flood control pond (Mill Pond), and the Westborough Reservoir are the three prominent water bodies contributing to Westborough's scenic character.  In fact, their natural beauty attracts town residents regularly for hiking, boating and fishing.  The town operates a swimming beach on the shores of Lake Chauncy.  The two large wetland systems of Cedar and Crane Swamps have a more subtle visual impact on the landscape. These ecosystems have played an important role in providing natural open space buffers and are important groundwater recharge areas.

The natural landscape of Westborough is being altered drastically by rapid development.     Poor site selection and design on the developers' part have the biggest impacts on the loss of landscape character. Most developers have the philosophy of bulldozing mature trees and replacing them with formal, uniform, non-indigenous street trees further disrupting the natural character of the area.  Just as there are a variety of housing styles to prevent visual boredom, so too should there be a variety of street trees.  Not only does variety provide visual interest, but would prevent decimation as a result of insects or disease.  Invasive species such as Norway Maple and Burning Bush should be avoided as landscape plants.

Landscape Character Impact on Recreational Opportunities and Development.  Fay Mountain would be a perfect spot to develop physical fitness trails and picnic areas, with its panoramic view of the whole town and much of eastern Massachusetts.  In fact, this mountain has such a unique vantage point that it might be attractive on the regional level as a fitness and observation site.

4.3      Water Resources

4.3.1      Watersheds

 Westborough is laced with numerous streams and water bodies.  Surface waters cover approximately 3 percent of the total land area of Westborough.  The town is divided into two principal watersheds, the Assabet River Drainage Basin and the Sudbury River Drainage Basin (part of the larger Concord River Basin), plus a small portion of the Blackstone River Drainage Basin. The headwaters for the Assabet and Sudbury Rivers are located within Westborough.  The Assabet River begins from the SuAsCo flood control reservoir near the Shrewsbury border.  The Sudbury River begins in Cedar Swamp near the Hopkinton border.

4.3.2      Surface Water.

4.3.2.1     Ponds and Lakes

Major natural water bodies include Lake Chauncy, Hocomonco Pond (Federal Superfund Site), and Cedar Swamp Pond.  The Westborough Reservoir (Sandra Pond) is an important surface water supply source for the town. The SuAsCo (Mill Pond) at the George H. Nichols Dam is a man-made floodwater retention impoundment for water flow augmentation at the headwaters of the Assabet River. Each site is described below, with the exception of Cedar Swamp Pond, which is addressed in 4.3.2.5.

Lake Chauncy  The lake is a natural “Great Pond” covering 185 acres.  It is a popular fishing spot, especially for largemouth bass, panfish, northern pike (stocked) and tiger muskies (stocked). The state maintains a public access boat launch on the west side of the lake.  A town-owned swimming beach is open to the residents of Westborough and Northborough in the summer.  This is a historically significant area because of past use by Native Americans and settlement by the Town's founding families. In addition to the swimming beach, Lake Chauncy has picnic tables, and a parking lot. A state boat ramp is present on the west shore. A trail network runs along the west and north shores of the lake on property belonging to the Massachusetts Fish and Wildlife Management Area (see below) and the Westborough State Hospital.  The trails provide connections to other parts of the Charm Bracelet trail system and to Little Chauncy Pond and Little Crane Swamp in Northborough.

SuAsCo Flood Control Project (Mill Pond/Nichols Dam) and adjacent Andrews-Nourse Property  This 325 acre pond is presently used for boating, fishing, ice fishing, ice skating and as a wildlife habitat. The standing dead trees in the pond provide nest sites for Great Blue Heron, Osprey (one of the few Massachusetts inland nesting sites), and Great Horned Owl.  The shallow pond (15 ft. max. depth) supports eight different fish species and is listed by Mass Wildlife as “one of the most productive largemouth bass waters in the state.”  The land immediately surrounding the pond is managed as an annex to Quinsigamond State Park.  The 83 acre town-owned Andrews-Nourse property (see below) borders the southwestern shores of the pond. Three municipal drinking water wells are located at this site within a few yards of the shoreline.

Westborough Reservoir (Sandra Pond)  The reservoir is a major drinking water supply for the town of Westborough. The man-made reservoir, surrounding Sandra Pond Conservation Area and Minuteman Park provide important fish and wildlife habitat.  Three certified vernal pools are located here.  It has the potential to become part of an open space corridor system in the southern part of town.  Trails around the pond are popular for hiking and nature observation while the pond itself is used for fishing.  Summer nature classes are offered to children by the Westborough Recreation Department. A watershed management plan currently being developed will include a forest cutting plan and a response plan in the event of a toxic spill on the abutting Massachusetts Turnpike.

Hocomonco Pond  In 2000, environmental regulators released this federal Superfund site from active cleanup of hazardous waste giving permission for passive recreation.  A study committee, appointed by the Board of Selectmen, has recommended permanent conservation of the land allowing canoeing, fishing (catch and release) and development of hiking trails, possibly linking to the Charm Bracelet system.   These plans have yet to be implemented.

4.3.2.2     Rivers and Streams

The major rivers and streams flowing through Westborough include the Assabet River, Denny Brook, Jackstraw Brook, Piccadilly Brook, Rutters Brook, headwaters of the Sudbury River, Whitehall Brook and a network of unnamed intermittent streams. Most drain into Cedar Swamp and all are relatively shallow and narrow.  Several historic mills once lined the banks of these water bodies.  The regulations of the Massachusetts Surface Water Quality Standards (314 CMR 4.00) classify the source of the Sudbury River, Denney Brook, Jackstraw Brook, Picadilly Brook, Rutters Brook, and Whitehall Brook as “Outstanding Resource Waters”.  These streams along with the Assabet River are “designated as a habitat for fish, other aquatic life, and wildlife, and for primary and secondary contact recreation” (Class B water quality).  The Assabet River from its source to the Westborough Sewage Treatment Plant is classified as “High Quality Water.”  Rivers and streams are ideal locations along which to site Charm Bracelet hiking trails because of the intrinsic beauty they provide.  Unfortunately, most rivers and wetlands are surrounded by recent and proposed private development, making it difficult to legally traverse via a public trail system.

Jackstraw Brook originates at Gilmore Pond near Fay Mountain and forms a wildlife corridor leading to Cedar Swamp.  Although the town and the Westborough Community Land Trust own some of the stream-front land, four recent developments have destroyed much of the upland surrounding Jackstraw Brook.  Anecdotal accounts suggest that only in recent years has Jackstraw Brook been drying up.  Massachusetts Division of Fish and Wildlife has declared Jackstraw to be an important trout stream.  Hiking trails have recently been constructed along the brook. There is still an opportunity to develop a trail next to Jack Straw Brook, located in the southern part of town.  Although much of the wetlands have been surrounded by development, there are opportunities to develop a trail system around some of these boggy areas.

The Assabet River begins in Westborough, meanders to the Northborough border, and ultimately merges with the Concord River. Starting from the SuAsCo the Assabet River offers great possibilities for hiking trails and a canoe launch because much of the land is town-owned or has been designated as open space by the Planning Board or is owned by the Westborough Community Land Trust.  Treated effluent from the Westborough Wastewater Treatment Plant empties into the Assabet River.

4.3.2.3     Aquifer Recharge Areas

The Comprehensive Wastewater Management Plan and Environmental Impact Report (2001) states that: “The existing water supplies consist of seven active wells, two inactive wells and Sandra Pond, which is a surface water supply.  The active wells are Chauncy Lake No. 2, Andrews No. 1 and 2, Wilkinson, Otis, Hopkinton and Morse.  The inactive wells are Indian Meadows which is under construction and Chauncy Lake No. 1 which is out of service until the pump is upgraded to a larger pump…All wells are gravel packed, range from 1 to 2 feet in diameter and tap unconfined aquifers.  The permitted yields range from 0.35 MGD (millions gallons per day) to 1.13 MGD per well.  The depth to bedrock is greater than 40 feet from the surface for all wells.”  Since this report was published, the Indian Meadows well has been completed and Chauncy Lake No. 1 has been repaired, so all nine wells are currently functioning.  A single water purification facility treats water from three of the wells and the surface water supply.  Locations of municipal drinking water wells and aquifer protection zones I, II, and III are shown on the “Aquifer And Watershed Protection Districts Map”. 

Westborough is currently engaged in an aggressive program of exploratory drilling of test wells in an effort to locate new water supplies.  Recent test wells located adjacent to Cedar Swamp have yielded acceptable levels of water flow, but permitting obstacles associated with the ACEC designation may prevent development of municipal wells at the site.  Future tests will involve both gravel type wells and, for the first time, deeper bedrock wells.  The required 400 foot radius of protected recharge areas surrounding a well head (Zone I) translates into a need for approximately 13 acres of undisturbed land around a well site.  As the town becomes more developed such sites are increasingly more difficult to find, independent of whether or not they yield sufficient flows.

Water use restrictions are imposed most summers, limiting outdoor watering of lawns and gardens.  These restrictions apply only to public water supplies.   Greater controls may need to be placed on water use from private wells, which tap into the same aquifer resources as public water supplies. Development within recharge areas and unregulated pumping of private wells has undoubtedly lowered the water table altering aquifers and drying up streams, vernal pools, and vegetated wetlands.

4.3.2.4     Flood Hazard Areas. 

Flood plains in Westborough generally conform to the pattern of wetlands and streams.  They comprise slightly more than 2,300 acres, or about 17 percent of the town. The 100- and 500-year flood zones are depicted on the “Water Resources Map - Surface Water, Flood Hazard Areas and Wetlands.”

4.3.2.5     Wetlands. 

The three major vegetated wetlands Assabet Swamp, Cedar Swamp and Crane Swamp in Westborough are depicted on the “Water Resources Map - Surface Water, Flood Hazard Areas and Wetlands”.  Vernal pool wetlands are described in section 4.5.2.

Assabet Swamp.  This wetland area starts near the SuAsCo reservoir and proceeds southwest from Arch Street and forms the headwaters of the Assabet River.

Cedar Swamp – The 1650 acre white cedar swamp was the first site in Massachusetts to be declared an Area of Critical Environmental Concern in 1975. Cedar Swamp is bounded by East Main Street (route 30, but also extends to the power lines) to the west, Flanders Road to the north, slightly beyond route 495 to the east, the Massachusetts Turnpike to the southwest, and route 135 to the south (Hopkinton Road) and southeast (South Street).  A railroad line bisects Cedar Swamp from east to west.  Cedar Swamp forms the headwaters for the Sudbury River.  It is an important recharge area for two municipal drinking water wells. This unique wetland area includes many vernal pools and habitat for rare Spotted Turtles and Hessel’s Hairstreak butterfly. Although largely inaccessible and underutilized, it provides opportunities for nature observation and canoeing. The Metropolitan District Commission and Sudbury Valley Trustees own and manage portions of the swamp. Charm Bracelet trails are proposed through portions of the swamp with side trails providing access to many of the upland areas. The potential exists to construct a boardwalk trail, which would provide public access to and increase public awareness of this ecologically and historically important habitat.  Cedar Swamp is also listed on the State Register of Historic Places.

Crane Swamp and adjacent Orchard Swamp are located northeast of Lake Chauncy and extend into Northborough.  This swamp drains via the Wachusett Aqueduct into the Sudbury River. This vast property provides an extensive wildlife habitat.  Large old hemlock and beech trees dominate sections of the forest and numerous depressions support vernal pools.  Much of the land is presently managed by the Metropolitan District Commission.  Trail links from the town’s Storey Fields on Haskell Street lead through the swamp and link to trails in Northborough. A popular trail linking the Sudbury Valley Trustees Sawink Farm and Cedar Hill reservations has been severed by construction of a MWRA water treatment plant, the trail will be rebuilt next in 2004 as part of the completion of the plant.

4.4      Vegetation

4.4.1      General Inventory and Forest Land

A systematic inventory of plant species has not been conducted in Westborough.  Approximately two-thirds of the remaining forested areas are hardwood and one-third coniferous with some mixed forest (figures are taken from the previous Open Space Plan).  A large portion of town was once covered by secondary forest formed after the abandonment of fruit orchards.  Much of these areas have been destroyed by housing developments.  Oak-Hickory forest communities dominate the hardwood areas, especially the Andrews-Nourse and Libby Properties. Most of these appear to have been logged within the past 50 years.  Coniferous vegetation is dominated by Eastern White Pine.  Dense stands of planted Red Pine surround Sandra Pond.  Unusual mixed stands of Eastern Hemlock and American Beech may be found in the uplands of Crane and Orchard Swamps.  Atlantic White Cedar and Red Maple dominate the forested portions of Cedar Swamp.  All three major swamps contain large amounts of Red Maple and various wetland shrubs.

Most of the remaining woodland areas are not conducive to active recreation because of the steepness of slopes. It does however, provide opportunities for trails.  The wetland areas are not conducive to active recreation, however, opportunities for trails are present.

The Massachusetts Wetlands Protection Act keeps the remaining vegetated wetlands safe from development. Trees are viewed by most developers as obstacles that cost money to remove. Although the zoning and subdivision by-laws have wording to minimize the removal of healthy trees within the public right-of-way, it is mostly by chance that trees are saved within subdivision development.  The philosophy to view mature native trees as a marketable amenity should be stressed in new developments.  This would help maintain the natural character that residents are so fearful of losing. As habitat fragmentation increases, so does the ratio of edge to interior habitat leading to increases in invasive plant species such as Common Reed Grass (Phragmites), Purple Loosestrife, Asian honeysuckles, Oriental Bittersweet, Japanese Knotweed, and Multiflora Rose.

4.4.2      Agricultural Land

While Westborough was once a thriving agricultural town, very little farming activity remains.  Nourse Farm and Glenrock Farm on Nourse Street (Route 30) are the only active farms raising fruits, vegetables, and a small number of cattle.  Both of these farms have Agricultural Protection Restrictions.  A small orchard remains active on Spring Road.  Two of the most active agricultural enterprises, Red Berberian’s and Arnold’s Orchard have recently been allowed to go fallow.  These areas have an uncertain future and have enormous potential as town open space, community gardens, athletic fields, housing subdivisions, or, in the case of Reds, as commercial space.  Three commercial nurseries/garden marts operate in town, Wilkinson’s Hi-Hill Farm on West Main Street, Harvey’s on route 135, and Green Thumb on Route 9.

4.4.3      Wetland Vegetation

Wetland vegetation in Westborough is typically shrub-scrub swamp dominated by Red Maple trees and a wide variety of shrubs such as Arrowwood, Spicebush, and Highbush Blueberry.  The most unusual wetland plant community is the extensive Atlantic White Cedar swamp.

4.4.4      Rare Species

The Massachusetts Natural Heritage and Endangered Species Program (NHESP) lists records of four rare plant species in Westborough.  The rare plant records are based on observations between 1931 and 1948. No recent effort has been made to verify their continued existence and they are probably extinct. NHESP ranks rare species based on their likelihood of extinction within the state with “Endangered” as the most threatened, followed by “Threatened”, and “Special Concern” as the least threatened.

Lyre-leaved Rock Cress (Arabis lyrata) is a cruciferous plant listed as Threatened and last seen in Westborough in 1931.  It prefers to grow on calcareous cliffs.  Since 1978 the plant has been documented in only two locations in Massachusetts.

Adders Tongue Fern (Ophioglossum pusillum) is listed as Threatened and was last documented in Westborough in 1948.  It is currently known from only eight locations.

Pale Green Orchis (Platanthera flava var. herbiola) is listed as Threatened and last documented in Westborough in 1934.  It is currently found in only eight Massachusetts towns.

Lion’ Foot (Prenanthes serpentaria), a member of the aster family, is listed as Endangered and was last seen in Westborough in 1935.

4.4.5      Sites having unique natural resources

These sites, which are described elsewhere in Section 4, include Cedar Swamp (Atlantic White Cedar, vernal pools, Spotted Turtle habitat, Hessel’s Hairstreak host plants, designated ACEC), Crane Swamp (old Eastern Hemlock forest), Sandra Pond Conservation Area (vernal pools), and Andrews-Nourse Property (vernal pools, fruiting American Chestnut).

4.4.6      Regional mapping projects

The Sudbury Valley Trustees has prepared the “SuAsCo  (Sudbury, Assabet, and Concord River Watershed) Biodiversity Protection and Stewardship Plan” (available at http://www.sudburyvalleytrustees.org/Biodiversity_Plan/Contents.html), which includes Lake Chauncy and Crane Swamp in its analysis.

4.5      Fisheries and Wildlife

4.5.1      Inventory

With three major ponds, numerous streams, large swamps, open fields, and forests, Westborough is fortunate to embrace a diversity of habitats that support a wide variety of wildlife.  Fauna identified in the 1974 "Natural Resources Inventory" include deer, rabbit, gray and red squirrel, raccoon, opossum, quail, trout, bass, pickerel, walleye, woodcock, skunk, many species of songbirds, birds of prey, waterfowl, reptiles, and small mammals like moles and shrews.  Since this time there have been sightings of beaver, black bear, coyote, fisher, moose, and turkey, all of which are on the increase in Massachusetts.  Raccoon numbers have probably decreased due to the rabies outbreak in the 1990s.  These animals are only as secure as their habitats.  The warning set forth in the 1974 Inventory is still apt: "Westborough is fortunate in having the opportunity to enjoy diverse and populous numbers of wildlife.  It can continue to reap enjoyment from them only if it takes steps to protect them.  For many neighboring towns, it is too late." Regrettably, there has been great decrease in wildlife habitat in Westborough due to rampant development.  As wildlife habitat is converted to suburban developments, some species will disappear while others well adapted to a suburban landscape may flourish.  White-tailed deer, for example, are known to thrive in suburbia where hunting is not allowed and ornamental plantings provide cover and food.  Potential results of continued deer population growth include damage to ornamental plantings, increase encounters between deer and automobiles, an increased host population for Lyme Disease, and in severe cases the deer population may exceed the carrying capacity of the environment leading to starvation.

The protection of the extensive wetlands in Westborough by federal and state legislation, has been the saving grace of much of the wetland habitats in Town.  The same can not be said for upland habitat.  For the most part, these wildlife habitats have lost out to residential and commercial development. Green belt corridors should be created that serve the community and wildlife, linking wetlands to uplands and linking islands of upland habitat.  There is no current plan to achieve this objective.

4.5.2      Vernal Pools

The “Aerial Photo Survey of Potential Vernal Pools” published by the Massachusetts Natural Heritage and Endangered Species Program (NHESP) identifies just over 100 potential vernal pools in Westborough, only a handful of which have been certified.  Potential pools were identified by interpreting color infrared aerial photographs.  The Wheaton College Vernal Pool Research Team under the direction of Dr. Scott Shumway has identified approximately 80 potential pools using the same methodology.  Certification of vernal pools with NHESP is the only way to effectively protect vernal pools in Massachusetts.  The Wheaton College Vernal Pool Research Team has studied and certified approximately twenty pools in Westborough and will continue to study pools for the foreseeable future.  However, the major obstacle to future certification efforts is obtaining permission from private landowners to access their property to study and certify potential pools.  Future protection of Westborough’s vernal pools could be enhanced by increasing public awareness of vernal pool habitat, encouraging private land-owners to allow pools on their property to be studied and certified, and by enacting town bylaws, to protect all vernal pools and at least 100 feet of the surrounding upland from filling or disturbance.

4.5.3      Wildlife Corridors

As woodlands and fields are developed into subdivisions and office parks the once large habitat is fragmented.  The result is a series of smaller habitat islands with an increased proportion of edge habitat.  Species requiring large home ranges are unable to survive in these fragments.  Similarly, as edge habitat increases, nesting birds and other interior forest species decline.  Edge habitat is subject to intense predation by raccoons, skunks, and domestic cats, nest parasitism by cowbirds, and colonization by invasive plant species.  Many species, particularly mammals and amphibians, require the ability to travel among habitat islands.  Regrettably roads and developments, frequently cross these travel routes, or wildlife corridors.  No effort has been made to identify or preserve wildlife corridors within Westborough and recent development has undoubtedly destroyed many important wildlife corridors and habitat islands.  The remaining large habitat islands are mostly wetlands.  Rivers and streams provide the best remaining linkages among these habitat islands (Cedar Swamp, Andrews-Nourse, Westborough Wildlife Management Area, Libbey Property, Sandra Pond Conservation Area, Crane Swamp in Westborough).  The lack of protection afforded upland adjacent to intermittent streams severely jeopardizes these potential corridors.  The Charm Bracelet Trail network, while intended for humans, is an excellent example of greenways linking larger parcels of open space and may serve as a good model for conserving wildlife corridors.  Old rights-of-way, such as the Shell oil pipeline, former trolley line, and power lines may also serve as important wildlife corridors and should be considered as areas worthy of future protection.  The Andrews-Nourse Property and Wildlife Management Area are productive areas for observing migratory songbirds while Lake Chauncy, Sandra Pond, and the SuAsCo (Mill Pond) are good places to observe migratory waterfowl.

4.5.4      Rare Species

The Massachusetts Natural Heritage and Endangered Species Program (NHESP) lists two records of rare vertebrates and two rare invertebrates in Westborough. The animal records are from the 1980’s and should be used to guide preservation of the habitat for these species.  A systematic effort to monitor their populations should be established.  NHESP ranks rare species based on their likelihood of extinction within the state with “Endangered” as the most threatened, followed by “Threatened”, and “Special Concern” as the least threatened.

Blue-spotted Salamander (Ambystoma laterale) is listed as a species of Special Concern and was last documented in 1986.  This species inhabits hardwood/hemlock forests and breeds in vernal pools.  The species is threatened by loss of critical vernal pool habitat.  There are currently 29 known populations in Massachusetts.

Spotted Turtle (Clemmys guttata) is listed as a species of Special Concern and was last documented in 1996.  The species is dependent upon vernal pool breeding grounds as well as the surrounding habitat. Spotted Turtles are threatened by development and fragmentation of wetland habitat, particularly habitats containing clusters of vernal pools. The turtles spend much of their time residing in vernal pools, but will also travel great distances overland. They have been documented in 139 towns with 40% of the records coming from Bristol and Plymouth counties.  Westborough’s Cedar Swamp serves as important habitat for this species.

Mystic Valley Amphipod (Crangonyx aberrans) is a small laterally flattened shrimp-like crustacean listed as a species of Special Concern and was last documented in 1986.  Mystic Valley Amphipod inhabits lowland aquatic habitats characterized by slow moving water.  Red Maple swamps may support populations of this species.  It has been documented in 40 sites in Massachusetts.  The species is threatened by loss of suitable wetland habitat.  Swampland to the south of Lake Chauncy is listed as probable habitat for the Mystic Valley Amphipod.

Hessel’s Hairstreak (Callophrys hesseli) is an inch-long green and brown colored butterfly listed as a species of special concern and last documented in 1988.    The larvae are dependent upon Atlantic White Cedar for a food source.  As a result, Cedar Swamp provides excellent habitat for Hessel’s Hairstreak.

4.6      Scenic Landscapes and Resources

The most recognizable scenic and unique resources in Westborough are shown on the map entitled "Special Features Map - Scenic Resources and Unique Environments." The natural and recreational resources of many of these areas have been described elsewhere in Section 4.

Lake Chauncy – Described in section 4.3.2.1

Crane Swamp and Orchard Swamp - Described in section 4.3.2.5

Newton Hill - Westborough quartzite was mined here by Native Americans.  Although presently an extensive office park, a beautiful vista overlooking Cedar Swamp and most of Westborough can be experienced from a parking lot. 

Cedar Swamp – An Area of Critical Environmental Concern described in section 4.3.2.5

SuAsCo (Mill Pond) and adjacent Andrews-Nourse Property The SuAsCo is described in section Described in section 4.3.2.1.  In 1988 the town of Westborough purchased 83 forested acres, known as the Andrews-Nourse Property, for open space adjacent to the SuAsCo (Mill Pond).  Approximately 20 acres of this property has been used subsequently for the construction of a new elementary school. Recently blazed Charm Bracelet trails cross the Andrews-Nourse property and follow over half the shoreline of the pond.  The Andrews-Nourse trails are popular for hiking, nature observation, and cross-country skiing.  Six vernal pools have been certified on the Andrews-Nourse property. Three municipal drinking water wells are located at this site.  A botanical inventory of the Andrews-Nourse Property was recently commissioned by the Westborough Community Land Trust and should soon be available to the public.

Jackstraw Brook - Described in section 4.3.2.2.

Depres Farm – The site of Eli Whitney’s birthplace, this privately owned parcel has the potential to become part of an historic town-wide open space corridor system and a nature preserve. The “Aerial Photo Survey of Potential Vernal Pools” published by the Massachusetts Natural Heritage and Endangered Species Program (NHESP) shows several potential vernal pools on this site.

Fay Mountain – The highest elevation in Westborough, this site is the critical link if the Town is to have an open space corridor in this southern, developing part of Westborough.  With it, one can traverse through a greenbelt corridor from Grafton all the way to the Westborough Reservoir.  It also provides for an open space link into the Depres farm and has the potential for a fitness trail.  Access is currently restricted as it is privately owned.

Westborough Reservoir (Sandra Pond) – Described in section 4.3.2.1.

Westborough Wildlife Management Area – The Massachusetts Division of Fisheries and Wildlife manages the 428 acre Westborough Wildlife Management Area for pheasant, deer, grouse, woodcock, cottontail rabbit, raccoon, gray squirrel, aquatic fur-bearers, and waterfowl.  The property includes woodland, small ponds, vernal pool habitat, a portion of the Assabet River, and the western shores of Lake Chauncy (section 4.3.2.1) where a boat ramp is maintained.  The land is managed to be an early successional habitat free of exotic species.  In addition to hunting and fishing the areas is used for nature observation, hiking, cross country skiing, snowmobiling, and flying model airplanes.

Scenic Roads – Westborough has a number of scenic roads with vistas, which capture the agricultural, rural woodland, or historic village essence that several decades ago characterized the town.  Because these scenic roads often pass through large tracts of developable land, their scenic quality is under imminent threat from development.  Chestnut Street, Bowman Street, Mill Road, Ruggles Street, and Gilmore Road have scenic vistas while West Main Street passes through the downtown historic district.

The Westborough Charm BraceletIn 2000 under the guidance of the Westborough Open Space Preservation Committee and the Westborough Community Land Trust construction began on a town-wide trail network. Known as the Westborough Charm Bracelet will encompass a 28.5 mile loop around town, side trails reaching most neighborhoods, and links to the neighboring towns.  The network is envisioned in the end to encompass 60 to 70 miles of trails.

4.7      Cultural , Archaeological, and Historic Areas

Founded in 1717, the Town of Westborough has a long and colorful history. The Town’s numerous historic resources are reminders of the various periods in the Town’s past. According to the Massachusetts Historical Commission (MHC), the Town’s inventory of historic resources includes 399 buildings, 37 other structures, 11 historic areas, 3 historic objects, and 1 burial ground. The objects include a fountain and two monuments, while the structures include 15 historic bridges (several of which are railroad bridges), a gate, a powerhouse, and a tower. The following subsections discuss some of the Town’s most noteworthy historic resources as well as mechanisms currently in place to preserve these resources. Current initiatives and needs with regard to historic resources are also discussed.

4.7.1      Westborough Historical Commission

The Westborough Historical Commission (WHC)  has initiated an extensive undertaking to examine and document the Town’s historic resources. As of 2002, 361 historic properties as well as the Lyman School property, Wessonville, and the Westborough State Hospital have been examined. All properties were evaluated through deed search, maps recorded and surveyed since 1795, and assessor's records. Each Survey Form describes the location, age and pertinent historical information and a black and white photograph as a visual affidavit. The surveys are on file at MHC and WHC as legal evidence.

4.7.2      Historic Districts and Multiple Property Listings

West Main Street Historic District

Originally listed in 1987, the boundary of this National Register district was extended further along Main Street in 1990. Roughly bounded by Milk, Main, Blake, and Fay Streets, the district originally comprised of 233 properties on 45 acres; in 1990, another 38 properties were added. The District consists of a well-preserved residential area that developed during the 19th century. Most house lots are regular ¼ acre lots and are uniformly set back from the sidewalk and street. Residences consist of a variety of single-family dwellings constructed between 1795 and 1900 and are of a variety of architectural styles including Federal, Greek Revival, Italianate, Second Empire, Queen Anne, and Colonial Revival. Public and commercial buildings in the District date from the mid-19th century through the early 20th century and are representative of professionally designed Greek Revival, Italianate, Victorian Gothic, and Classical Revival style architecture. The District represents the Town’s evolution from an early agricultural settlement to a diversified manufacturing town.

Massachusetts State Hospitals and State Schools

This National Register Multiple Property Submission (NRMPS), added to the National Register in 1994, includes 14 districts within 19 towns, encompassing 111 properties. Westborough properties in the NRMPS include a portion of the Lyman School for Boys and properties associated with the Westborough State Hospital. The Westborough State Hospital site includes a total of 63 properties, some of which are located in Northborough. The total land area of the campus is 650 acres. The Westborough State Hospital of 1884 was designed to incorporate the original 1848-1876 building of the State Reform School for Boys, and not only represented an early case of adaptive reuse within the institutional system, but also preserved the hospital’s oldest component (the western end of the Main Hospital Building designed in 1848 by Elias Caster and James Savage). During rehabilitation of the old building, the state’s first congregate dining room was constructed to allow patients to interact within an environment similar to that of a “large hotel.” This model, which was designed to heighten the patients’ sense of normalcy, was adopted at most later hospitals. The Westborough Hospital was also unique in that it was the second state hospital in the nation to offer a treatment based on the principles of homeopathy, emphasizing rest, massage, hydrotherapy, and special diet, eschewing hypnotic medications. The hospital was also actively engaged in education, holding clinics for Boston University Medical School students as early as 1887, and establishing a nurses’ training school in 1890.

Lyman School for Boys

Several portions of the Lyman School for Boys, located at Oak and Park Streets and Route 9, have been listed as a National Register District since 1994, as part of a Multiple Property Submission. In 1997, a Preservation Restriction was extended to these six listed properties. The campus, centered on the top of scenic Powder Hill, was the first campus in the state system to adopt the cottage plan, so buildings are dispersed on the south and west hill slopes. This plan avoided a large centralized structure in favor of dispersed “Family Houses” to encourage a more personal atmosphere. Four of the pre-existing dwellings remain on the Lyman School campus, including the individually listed Nathan A. Fisher House and Maples Cottage. In 1846, the General Court appointed a committee to study the need for a state institution for reformation of juvenile offenders after being petitioned by a group of concerned magistrates and citizens. Prior to this, juvenile offenders were generally confined in jails and prisons with hardened criminals. The former Lyman School was established as the Massachusetts State Reform School in 1847, the first state-operated reform school in the country.

National and State Register Historic Archaeological Districts

The Town has many archaeological resources, historical Native American trails, and areas where settlement dates back to the 1600s. Two such areas have been added to the National Register:

·        Cedar Swamp Archaeological District: This district straddles the Town’s border with Hopkinton and was added to the National Register in 1988. It is the second largest such site in the state.

·        Charlestown Meadows Site: A Preservation Restriction was extended to this site in 1995.

4.7.3      National and State Register Individual Properties

Nathan A. Fisher House

This two-story Federal style house of timber-frame construction is located on Turnpike Road. The site was added as an individual listing to the National Register in 1980, protected by a Preservation Restriction in 1990, and included as part of a multiple property submission in 1994. Nathan A. Fisher was an early Westborough merchant. Fisher and his brother in law, Joseph Lothrop, opened the Town’s first store in a section of Fisher’s house by 1826. Fisher and Lothrop later constructed a thread factory on the property, which was the Town’s first steam powered industry. In 1884, the state acquired the house and several adjacent properties to be used as part of the Lyman School, and the house was used for a time as a residence for school staff. This structure is presently being restored and will eventually house the Westborough Heritage Museum.

Maples Cottage

Maples Cottage, located on Oak Street in the original 18th century town center, is a two-story Federal/Greek Revival design. The building has been an individual listing on the National Register since 1980, was part of a Multiple Property Submission adopted in 1994, and was the subject of a 1997 Preservation Restriction. William White, a prosperous farmer, built the structure that presently exists on-site circa 1830, reportedly from materials salvaged from the site’s previous structure, a home built in 1725 by Westborough’s first minister, Ebenezer Parkman. In 1884, the Commonwealth acquired Maples Cottage and surrounding farmlands for the Lyman School. This building was used as a staff residence until farming was phased out of the curriculum of the Lyman School.

Jonah Warren House

This structure, located at 64 Warren Street, was constructed circa 1720-27 and has been listed on the National Register since 1998. The Jonah Warren House is one of the “finest and best-preserved examples of 18th century domestic architecture in Westborough” (MHC inventory form). The house has a long association with a number of prominent citizens in Westborough’s history, including Jonah Warren, Aaron Warren, and Hercules Warren Fay. Jonah played an important role in the Town’s early settlement. Aaron was a cordwainer who shipped his wares to the South, paving the way for Westborough’s second major industry (after straw hat manufacturing). Aaron’s great grandson, Hercules Warren Fay, went on to become Westborough’s most distinguished man of letters, moving in the same literary circle as Henry James and William Dean Howells.

Joseph Lothrop House

This house, at 208 Turnpike Road (Route 9), is a square-plan, Federal style house whose fine detailing represents the area’s major period of significance. The house was added as an individual listing to the National Register in 1980. Located in the original 18th century town center, the building has a significant historical association with the early development of the Town. John Lothrop built the house circa 1825. Lothrop and Nathan Fisher opened Westborough’s first retail store.

4.7.4      Other Historic Resources

The following historic resources were previously deemed eligible for National Register listing, but at present are still not listed or require additional research to evaluate whether or not they are eligible for National Register listing:

·        Rocklawn Historic District (Old Flanders Road)

·        Eliezer Rice House (37 Maynard Street)

·        Conrail over Mill Pond (Boston and Albany Railroad Bridge No. 33.12.)

·        Whipple House (59 Fisher Street)

4.7.5      Existing Protection for Historic and Archaeological Resources

Westborough currently has several provisions in place to preserve historic buildings and structures. These include the Demolition Delay Bylaw, Design Review Board, Sign Bylaw, Open Space Communities Bylaw, and Site Plan Review.

·        Demolition Delay Bylaw: Article 28 of the Town’s Charter and Bylaws establishes a demolition delay process that requires that any building built prior to 1900, listed on the National Register, included in the Historic District, or researched by the WHC and found to be historically significant, is subject to demolition delay of 90 days. During this time, the WHC will try to work with the applicant to find a feasible alternative to demolition, such as preservation or restoration.

·        Design Review Board: A five-person Design Review Board appointed annually by the Planning Board administers design review. Subjects of design review include landscaping, relation to the built environment, materials, textures, color, roof slopes and materials, scale, signage, external lighting, windows, open space, historic resources/heritage, and costs.

·        Signs Bylaw: Article 3337 regulates signage in and near the Town’s Historic District and authorizes the WHC to issue a binding decision on whether or not a sign is appropriate for inclusion in the Historic District. This bylaw requires that all signs erected, altered or relocated within the Historic District or any zoning district within 2500 feet of the downtown rotary must be consistent (in design, materials, lettering and color) with the historic character of that district. The WHC is charged with preparing the sign guidelines while the Planning Board is authorized to approve them. The Building Inspector is responsible for enforcing the Bylaw.

·        Open Space Communities Bylaw: The Open Space Communities Bylaw seeks to preserve, among other features, the Town’s historic sites and vistas.

4.7.6      Future Plans for Historic Preservation

The WHC has recently completed a Historic Preservation Plan for the Town. This document includes historic and archaeological profiles of the Town; a timeline summary of previous historic preservation activities undertaken by the WHC and the Town; a compendium of local, state, and federal regulatory measures and programs available to the Town for historic preservation; and identification of future preservation activities. Some future preservation activities include the adoption of new bylaws, the expansion of existing historic districts, and the creation of new historic districts. Potential bylaws identified in the plan include a Scenic Road Bylaw and a Historic Landmark Bylaw that would protect distinctive structures and landscapes in the Town.

The WHC has initiated a second expansion of the West Main Street Historic District. This expansion includes a section of South Street to School Street as well as Charles, Central, and Cross Streets, Harrison Avenue, and parts of Ruggles Street. The Commission’s future plans include seeking a historic designation for “Vintonville,” an area accessible via South Street and known as the “Tree Streets,” i.e. Pine, Elm, Cedar, Beach, and Green Streets. The houses here were built by Otis Vinton from 1850-1870 for the migrant Irish and Italian workers who came to lay the tracks for the railroad and later the trolley lines. Another area identified for historic district designation is the area surrounding East Main Street, including High, State, Water, Lincoln, and Spring Streets. Nineteenth century merchants and manufacturers built the homes in this part of Town that include a variety of architectural styles.

4.8      Unique Environments

The Cedar Swamp ACEC (Area of Critical Environmental Concern) is described in 4.3.2.5.

4.9      Environmental Problems

4.9.1      Hazardous Waste and Brownfield Sites

The Department of Environmental Protection has classified the majority of gas stations in Westborough as potentially hazardous to the groundwater due to leaking petroleum storage tanks. Efforts are currently under way to replace all leaking petroleum storage tanks.  Appendix E is a list of the current hazardous waste sites in Westborough whose file has not been closed by the Department of Environmental Protection.

Hocomonco Pond is a Federal Super Fund priority site.  Creosote was released at a former industrial site nearby resulting in a release into the soil, groundwater, and surface water. The site is owned by the Town and is currently finishing a cleanup operation.  Currently it cannot be used for recreational purposes but discussions are currently underway to allow a walking trail on an old road in the property.

4.9.2      Landfills

There are no active landfills in town.

There are three landfills in Westborough that are no longer used.  They are at E. L. Harvey and Sons on Hopkinton Road, at the DPW off Oak Street and near the Tyrolit / Bay State Abrasives Industrial site near Cedar Swamp. Contamination to the groundwater or surface water has not been detected.

4.9.3      Erosion

Most of these problems in the Town are sedimentation from development (see below).

Although new subdivision development must provide storm water detention basins to capture and filter run-off, the older subdivisions and Town roads do not have this ability. Creative, natural Town-wide detention basins with man-made wetlands to filter storm water run-off should be considered for implementation prior to release into the surface water.

4.9.4      Chronic Flooding 

The Board of Health keeps the flood insurance maps for the town.  There are no chronic flooding areas to report.

4.9.5      Sedimentation

Most of these problems in the Town are the direct result of developers stripping the land of its vegetative cover.  Proper re-seeding, hay baling, and silt fencing seem to curtail the problem during light rainstorms, but not during the average, and certainly not above average, rainstorms.

4.9.6      Development Impact

Perhaps the greatest environmental challenge that affects open space and recreation planning is the effect of industrial and residential development.  These challenges are well documented elsewhere in this plan.

4.9.7      Ground and Surface Water Pollution

Leaking petroleum tanks are the major known direct potential contaminators of water.  Road water run-off is known to contain salts, oil, gas, rubber, lead, petroleum by-products, dead animals, feces, home fertilizer, etc.  These are significant contributors to pollution and can contribute to the contamination of surface and ground water.

4.9.8      Impaired Water Bodies

Hocomonco Pond will remain a limited use site because of creosote contamination.

4.9.9      Conclusions 

The extensive rolling hills, wetlands, and surface waters give Westborough its overall unique appeal. Westborough has many natural features that safeguard the existence of wildlife and enhance the quality of life of its residents. To ensure this appeal continues for future residents, the current erosion, sedimentation, and re-vegetative practices must be strictly enforced whenever development is taking place.    Not only will this mitigate the negative impacts on wildlife, but it will help to maintain the rural character the residents are so fearful of losing.
