Should you have any questions or comments regarding this submittal, or if you require any additional information, please contact our office at (978) 465-1428. Sincerely, VINE ASSOCIATES, INC. 11�� Susan St. Pierre Project Manager J CC: J.H. Rockett I / Pond Riverfront Restoration and Planning Plan 96 Swampscott Road Salem, MA The very shrubby woody plants along the slopes of the pond are crabapples (Malus spp.). It is widely planted as an ornamental flowering tree/shrub. The vast majority of these plants are on the previously landscaped slopes of the pond and driveway, and not at the base or within the resource area itself. Very little of its canopy cover extends to the edge of the pond. Therefore, the removal of these plants should have little to no affect on the shading of the pond. Many red maple(Acer rubrum) seedlings were observed along the edge of the pond. Many of these seedlings are at least three to four feet in height. The removal of the crab apples should provide more light to these plants and allow them to grow at a rate faster than their current growth rate. They will eventually grow to a height sufficient to provide additional shade to the pond. Other species observed along the.edge of the pond include various birches (Betula spp.) alder(Alnus spp.), willows (Salix spp.) and buckthorn (Rhamnus frangula). While most of these species are native and should remain, the buckthorn should be removed. The remaining native species will also provide shade to the pond. . The steep slopes along the westerly side of the pond the will be planted with a New England Conservation/Wildlife mix,which would provide a no-maintenance permanent ground cover of grasses, wildflowers and other native species to provide both erosion control and wildlife habitat value. Meadowsweet(Spirea latifolia), a native shrub that grows from 2' to 4' will also be planted in this area. Attachment A (submitted with Request for Amendment to Order of Conditions) Riverfront Area Restoration Plan 96 Swampscott Road Salem, MA The project site at 96 Swampscott Road in Salem, Massachusetts is a previously developed industrial site approximately thirteen acres in size. It currently contains an existing, vacant building and parking areas. The site is bounded on the north and west by two adjacent industrial/commercial sites. A junkyard lies directly south of the site and a commercial fitness center is located southeast of the site. Swampscott Road runs along the.eastem boundary of the site. Forest River, a perennial stream, runs through the eastern portion of the site,directly adjacent to Swampscott Road. An unnamed stream runs through the southern portion of the site, between the existing pavement and bordering junkyard. These streams are shown as being perennial on the United States Geologic Survey topographic map. The unpaved areas within the site are primarily forested and consist of both upland and wetland areas. On-site wetland resource areas include Bordering Vegetated Wetlands(BVW), Inland Bank, Land Under Water, and Riverfront Area. The BVW and a portion of the Land Under Water are located within the Riverfront Area. The Riverfront Area within this site was originally altered during building construction and site development in the early 1980s. Because the site is not currently occupied and in use, large amounts of trash and debris have been dumped at the site, both within the paved and unpaved areas, including the Riverfront Area and other on-site resource areas. The debris includes building materials of various types, metal appliances, tires, aerosol cans, bottles, organic,debris including dumped brush, and other miscellaneous trash. The Riverfront.Area adjacent to the Forest River in the eastern portion of the site extends from the top of the Bank of the Forest River out 200 feet, and includes forested uplands, a Bordering Vegetated Wetland, a man-made pond, and portions of the existing building, driveway and parking lot. The upland section of the Riverfront Area closest to the Forest River is primarily forested with red oak(Quercus rubra) and wild black cherry(Prunus serotina)as the dominant tree species. Sweet pepperbush, buckthorn (Rhamnus cathartica), and bush honeysuckles(Lonicera spp.) are common in the shrub layer. The vine layer is dominated by multiflora rose(Rosa multiflora), Asian bittersweet(Celastrus orbiculata)and poison ivy(Toxicodendron radicans). Catbrier(Smilax spp.) is also common in the vine layer. Multiflora rose(Rosa multiflora)and Japanese knotweed (Polygonum cuspidatum) are also common along the wetland/upland boundary. A large granite outcrop separates the upper portion of the Riverfront Area from the lower portion. The canopy of the BVW in this area is dominated by red maple (Acer rubrum). Green ash (Fraxinus pennsylvanica) is also present. Highbush blueberry(Vaccinium.corymbosum) and sweet pepperbush.(Clethra alnifolia) dominate the shrub layer. A large patch of common reed(Phragmites australis) exists next to the edge of the man-made pond close to Swampscott Road and the Forest River. Japanese knotweed also occurs near the banks of this pond, and cattails(Typha spp.)occur within the pond near the culvert that runs under Swampscott Road. Many of the species that occur on-site, and often dominate an area, are considered to be exotic invasive species. These species include buckthorn,honeysuckle, multiflora rose, Asian bittersweet, Japanese knotweed, and Phragmites. Other exotic invasive species observed on site include Japanese barberry(Berberis thunbergii) and Tree-of-heaven (Ailanthus altissima). Native species can also become invasive at times. These species may include catbrier and poison ivy. The presence of such a largemumber of invasive species throughout the Riverfront Area impacts the area's natural ability to function to its full potential, especially for providing wildlife habitat and maintaining natural diversity. Restoration of the Riverfront Area is proposed for offsetting impacts created through the installation of parking area within a Previously Developed Riverfront Area. A total of 26,800 square feet of Riverfront Area is proposed to be restored. The restoration of the Riverfront Area includes the removal of the large.amount of trash and other debris that is present throughout the Riverfront Area and the BV W. The restoration plan also includes the removal of many of the invasive species previously listed. Woody species to be removed include buckthorn, honeysuckle, Japanese barberry, multifora rose, and Asian bittersweet. Individuals of these species will be be identified and clearly marked by a trained wetland scientist prior to removal. The preferred method of removal for these species is physical removal through hand-pulling or with a grubbing hoe. Physical removal is often highly effective for shallow-rooted plants such as buckthorn and honeysuckle. Cutting is also an effective method for individuals which are too large to remove. If individuals are cut rather than uprooted, the initial cutting will occur in May or June and will be repeated at least two more times during the growing season. In some cases, as determined by the wetland scientist, chemical treatment for larger stumps may be required. In such cases, chemical treatment will be conducted by a licensed professinal using only the minimums( amount of the proper herbicide. Herbaceouse plants, such as Japanese knotweed, Phragmites, and purple loosestrife,tend to be much more difficult to control, and practically impossible to eradicate. Japanese knotweed and Phragmites occur in clumps in several locations in the eastern portion of the site. These species will be cut and removed from the site. The ground surrounding the plants will then be covered with a black plastic bag or shadecloth, to prevent the re- sprouting of these plants. This area will be planted with low-lying native shrub species such as Meadowsweet, Elderberry, Wild Raisin, Bayberry and Highbush blueberry with the shadecloth still in place. These species also respond well to cutting followed by applications of glyphosphate. However, a more natural control of these species is desired above the use of herbicides. In order to restore the Riverfront Area at this location, large amounts of debris will be removed from the site. Invasive species, many of which occur within the shrub and vine layers, will also be removed. The removal of these shrubs and vines will allow for greater natural regeneration of native tree and shrub species, enhancing both wildlife habitat and natural diversity. Any other invasive species listed by the U.S. Army Corps of Engineers and Massachusetts Natural Heritage and Endangered Species Program that are observed on-site will be documented and removed.
