Perocci 394 Boston Street North Andover, MA 01845 Commonwealth of' Massachusetts Division of Land Management Boston, MA MERWMACK ENGINEERING SERVICES, INC. • 66 PARK STREET • ANDOVER, MASSACHUSETTS 01810 STATEMENT OF ENVIRONMENTAL IMPACT TEOMA ESTATES NORTH ANDOVER, MASSACHC3SETTS SUBMITTED BY: MERRIMACK ENGINEERING SERVICES 66 PARK STREET ANDOVER, MA MERRIMACK ENGINEERING SERVICES INC • 66 PARK STREET • ANDOVER MASSACHUSETTS O1810 STATEMENT OF ENVIRONMENTAL IMPACT TEOMA ESTATES PURPOSE The purpose of this report is to satisfy the Town of North Andover Subdivision Regulations which require that the applicant for subdivision approval submit a Statement of Environmental Impact to the Planning Board. In addition to this report, a set of definitive subdivision plans, 24" x 36" in size, which show the lot layout, plan and profile, construction details, and also the topography and grading, are included, The Lot Grading and Topographic Plans show the existing and proposed' topography at two foot contour intervals, along with the location of existing structures, fences, and walls. In addtion, the plan shows the existing vegetative cover, as well as all major tree groupings and other botanical features which are of importance which might exist on the site. Important wild life habitats, as well as areas which will not be disturbed by construction are shown on the plan. The plan shows the location of test pits and percolation tests which were taken on the site, as well as 'the soil types based 'on the-United States 'Department of Agriculture Soil Study. The location of these test pits designate the areas in which ground water table elevations were recorded, and these are contained on the enclosed perc test and test pit report enclosed with this statement. The seasonal high ground water mark can then be determined through a review of these reports and the plans together. In addition, the wetland elevation is shown on the plan. Plans which show the drainage area watershed are delineated separately but enclosed within this report for use and consideration. PHYSICAL ENVIRONMENT The site consists of approximately ll+ acres, located on the Easterly side of Boston Street in North Andover, P .A. The entire site is wooded with trees which include hardwood and pine. These trees are mixed throughout the site, depending on the soils which exist on each individual section of the site. In addition, a wetland area exists on the site, in the front area of the parcel, as well as immediately adjacent to the two streams which traverse the site. The topography is generally varied, and slopes from the East in the rear of the site, down to Boston Street, the Western boundary of the parcel. A series of small, hills and valleys exist on the premises. Some ledge outcrops are on the site, as well as many large boulders scattered throughout the premises. Other than a large boulder existing in the Easterly portion of the site, there are no special or unusual geological features which are not indigenous to New England, and North Andover. There are no specific scenic areas, TZ) our knowledge there is no record of any special historical features, except that .the appearance of an old foundation does exist on the site, on lot 1. Trails exist on the site, in the form of MERRIMACK ENGINEERING SERVICES. IN( • 66 PARK STREET 0 ANDOVER, MASSACHUSETTS 01810 2 . gravel cart roads or woods roads, which run from one parcel to the other adjacent parcel in a random fashion, through the site. These appear to be old logging roads which provided access from Boston Street into some back land parcels. These probably were put into exist anae when all of the land was under common ownership. Adjacent.to the premises is land owned by the Commonwealth of Massachusetts , Division of Land Management. This land is part of the Harold Parker State Forest System, and is not to be developed by the Commonwealth, but held in reserve for open space. At na tiXe was any endangered wildlife observed on the premises. Wildlife which is 'indigenous to this area include waterborne creatures which normally exist in and around wetlands, as well as indigenous wild life to wooded areas. These include chipmunks and squirrels as well as various types of birds. The proposed development will not impact any of the features.:mentioned above in a negative fashion. The proposal calls for the development of nine lots,' all of which can accommodate the construction of a single family home. All of the Lots will be a minimum of one acre in size. All of the lots will be serviced with a roadway approximately 850 feet in length. The roadway has been laved out to minimize negative impact upon the site, but does in fact cross two different streams at one point. The first roadway crossing is through and across a main brook which is culverted at the woods road previously described. This culvert will be removed, and replaced with a new pipe line which is the full width of the right of way. In addition, a secondary stream will be crossed by the roadway, by means of a culvert placed thereunder. The culverts have been designed to accommodate the flow for a 100 year storm. Only those trees which must be removed to accommodate construction of the roadway will be lost or removed for construction of this project. In addition, trees which are located in the areas of subsurface disposal systems and proposed houses, including areas of regrading will be removed from the site. It is not proposed to remove any other trees fromm the site, but to maintain as many of the trees on the premises as possible. None of the gravel cart paths or roads will be removed from the site but in fact will disappear in places , due to the construction of the houses and leach fields on the site, The construction of the major roadway into the site will cause the disruption of some of those cart paths. A title search by the attorney for the subdivider did not turn up any prescriptive rights in the roadways , and therefore, the integrity of the cart paths need not be maintained by the subdivider. All of the stone walls which exist around the perimeter of the site will be maintained by the developer, and wherever possible, the stone walls which transect the site will be maintained on the premises. As few wetlands as possible will be disturbed, and in fact , the roadway and drainage system has been layed out so as to provide a minimul disruption of the wetlands by the construction. In order to minimize the impacts of this construction on the site, hay bales and other erosion control devices will be placed in critical areas of the site. This project will not impact in a negative fashion any special historical features, or displace any endangered wild life , as none has been identified on the premises. Any soil which i;: diLrupted, will be graded properly so MERRIMA(K I H 11+I I R1IU ','it A' I" u+ • h5 P�-RK SIREET • ANDOVER MASSACHUSEITS 01810 3 as not to allow the ponding of surface water. The resulting surface will be foamed and seeded or treated with bark mulch until' a permanent vegetative cover is put in place. The land use within the development will consist of single family homes , ' serviced with municipal water. Subsurface disposal systems (septic systems) "will'be Gonsti^ucted on each lotto service each of the homes. The water main will be extended by the developer down Boston Street, from Grey Street, as no municipal water main currently exists within Boston Street at this time. The roadway, approximately 850 feet long, will contain storm drainage and water mains as all designed and layed out in full accordance with the Town of North Andover Subdivision Regulations. The roadway will, consist of a 26 feet wide bituminous concrete road, with a closed cul-de-sac at the end. A Cape Cod type berm will be constructed on each side of the roadway to direct water in the gutter to the catch basin, storm drainage system. The area behind the bituminous concrete curb will consist of loam and seed, as no sidewalks are proposed to service the development at this time, since none exist on Boston Street. The proposed land use is compatable with the existing land use in the neighborhood, since all single family homes and public open space exist within area adjacent to this project. No pollution of ground water is "'anticipated since all of the 'septic systems will be designed in accordance with the State Sanitary Code. No harmful pollutants'Mill be generated from the residential site development. Since erosion control and sedimentation control will be put in place during construction of the roadway and other improvements, no other negative impact upon the neighborhood will be generated. SURFACE WATER AND SOILS Within the development , a wetland area exists in the front of the site , adjacent to Boston Street. This wetland is fed by an intermittant brook which runs from the North of the site, into the wetland, towards the South portion of the site. A smaller strewn runs from the land of the Commonwealth of Massachusetts , in the Southeast quadrant of the site, Northwesterly toy. this large brook. The outlet from the wetlands is controlled by a 12" x 2411 oval corrugated metal pipe which passes under Boston Street. The land uses to the South of the site, specifically two single family dwellings as well as a portion of the open space from the land of the Commonwealth of Massachusetts , all drain onto a portion of the site. In addition, the land to the North of this site also drains into the brook which traverses this property. All of this drainage enters the wetland area in the Boston Street portion of the site. The wetland in this area, consists of a wooded vegetative wetland which has skunk cabbage, some blueberries, red maple, and few cedar therein. A portion of the site drains to the east property line, onto land owned by Brown and the Commonwealth of Massachusetts. This separate and distinct watershed does not have any defined channel leading from it. Only a small amount of overland flow leaves the premises to the neighbors lands in this area. Attention is called to the watershed plan for 'a• more definitive description of this area. MERRIMACK ENGINEERING SERVI(15 IN( • ec PARK STREET • ANDOVER. MASSACNUSETTS 01810 4 Luring construction, as much of the wetland and stream areas which can be protected, will be protected. Hay bales and siltation fences will be placed where shown on the plan in a protective radius around these wetlands and streams, to prohibit surface and sediment pollution' of these watercourses. These siltation fences and hay bales are devices approved by the United States Soil Conservation Service for protecting such sensitive areas. It will not be necessary to provide temporary siltation ponds or sediment basins, as the degree of erosion from the site will be minimized by the maintenance of the existing vegetative cover wherever possible on the site. The trees and matting which exist will reduce the runoff of soil from the site into these regions. The maximum amount of vegetation removal which will occur at any time, will be at the time the roadway is first cut into the site. At this time, it will be necessary to remove 1.3 acres of tree cover in order to accommodate the slopes and the roadway construction called for on this plan. No other tree clearing will be done during this time. This vegetation will be removed only after the erosion control devices have been put in place by the developer. All of the brush will be chipped on the side, and stored for reuse as mulch and erosion control. The logs will be removed from the site using standard logging methods. " The 'right 'of way will b6`''g�.,,., .,.. grub.bed' and`c eared in preparation f excavation. The stumps will the removed from the premises anod put into an approved dumping ground, or buried along a-property line in an approved area. Loam will be stipped and stockpiled in an area which is at least 100 feet away from all of the streams and brooks on the site. This loam will be reused as part of the road construction, and lot finish grading. The subgrade will then be prepared with excavation using a large bulldozer. Any fill which is necessary to be brought onto :;he site will be done so at this time, where as any excess material will be stockpiled in an area more than 100 feet away from any of the wetland area or water courses. Util- ities will then be constructed within the roadway, and upon completion of these utilities the gravel subgrades will be installed. The road will be finish graded, paved, and the side slope loam and seeded. It is anticipated that no longer than six months of actual construction time will be necessary to build the entire roadway as described above. The maximum length of time for loam to be stockpiled on the site would then be five months , and which if maintained for any longer period, would be covered with a matting for other erosion control devices such as seed or hay. Lots shall be cleared only after the roadway has been grubbed and cleared and erosion control devices of an appropriate nature have been put in place. Stockpiling of soil will be done' '.in the same fashion as. specified for the roadway, and all site contrucion on each lot shall be completed within six months from its commencement. Approximately 1.5 acres of trees and vegetation must be cleared and removed to accommodate construction of the septic system the house and driveway on each lot. The areas in which the vegetation is removed, will be replaced with loam and seed and therefore a grass lawn. This will occur even in the area of septic systems, but will not occur in the area of driveways which will be paved. The maximum amount of time that any lot will be disrupted would be approximately six months, since this is all of the time which is necessary for the developer to clear the lot , constuct the home, MERRIMACK ENGINEERING SERVICES INC • 66 PARK STREET • ANDOVER, MASSACHUSETTS 01810 5 and then complete the site landscaping. No negative impacts upon any adjacent properties are expected by utilizing the above schedule and procedure, and no negative impacts are expected to 'occur to any of the streams or wetlands by use of this procedure. Methods to control erosion and sedimentation include the provision of catch basins with sumps - according to Town standard, which will trap sediment before it can enter any stream or wetland area. The surface drainage system will be piped from catch basin into manholes, to allow access into the pipe lines for cleaning purposes. Land around the outlet of pipes as well as inlets of cross culverts will be maintained in place with the use of flared concrete bipe ends; e4ith' rip-rOp so as to not _allow any erosiorCafter the_ improvements which are proposed . have been placeil. The land will be graded to a maximum slope of 3 to 1, and therefore will be a stable slope which will not allow any erosion or sedimentation to occur within the waterways. All of the disturbed and graded areas will be affixed with a permanent vegetative cover in the form of grass or other approved legumes. The existing vegetation within the wetlands will be protected with the erosion control devices that have described above. Trees will not be disrupted when adjacent to construction but will be protected so as to 'maximize the value of the site. The development will blend with the topography, as no major regrading is taking place except to accommodate septic systems, the roadway on a minimul basis, and the homes as might be necessary to accommodate the septic system tie-ins. No marshes will be disrupted with this project, and the only shore line and seasonal wet area which will be affected will be the crossing of the streams with the roadway, which is necessary to access land which would otherwise not be accessible from a public way. There are no existing flood control or wetland easements on the site , but drainage easements are proposed in areas which will contain permanent drainage devices , and which be accessed for maintenance of the storm drainage system. Increases in the peak rate of runoff caused by the altered surface conditions will be mitigated through the use of storage within the existing wetland area on lot #9. The outlet from lot 9 doer control the inflow from the major brook previously described. This control structure will continue to control the flow from the site so that a 0% increase in the rate of runoff from the premises will result. Modification to the inlet in the form of a control structure to be built around it will be provided by the developer. Wherever possible, ground water recharge is being utilized, and in this case , in the large wetland and retention area on lot #9. All of the lots will be serviced with septic systems which will be constructed in accordance with the Town of Worth Andover and State Sanitary Code, Since these are constructed according to the codes, no negative impact on the ground water or soils will result. The soils are conducive to the construction of the septic systems, as the percolation tests indicate relatively permeable soil well within the cut off limits for the installation of subsurface disposal systems. In .addition, the ground water table in all cases is low enough to accommodate the construction of the septic systems with minimal. MERRIMACK ENGINEERING SERVICES INC 0 66 PARK STREET 0 ANDOVER, MASSACHUSETTS 01810 6 regrading required. Because these septic systems will be regraded in accordance with the State Sanitary Code, no ponding of surface water on the premises shall occur. SUBSURFACE CONDITIONS The test pit and percolation test results which have been taken in the presence of the Town of North Andover, Bozrd of Health Inspector in the Spring of 1984, indicate that the septic systems can be constructed in accordance with Town and State regulations on each lot. There are few, if any, limitations to the proposed project caused by subsurface soil and water conditions. In some locations, ledge and bedrock was found at elevations less that 4 feet from the surface. In these areas of the site, no septic systems can be constructed. In addition, septic systems will not be constructed in wetlands, or within 100 feet from them. In all cases, the lot lines have been layed out to allow the construction of subsurface disposal systems on each lot. In particular, lot 9 provides a configuration of lot layout which is not considered rectangular or normal, but one which is specifically set up to allow for the construction of subsurface disposal systems to service a home on lot #9, in addition of the propoaed flood storage pond. The percolation tests were done in accordance with`the State Sanitary Code, in the presence of the Town of North Andover Board of Health Inspector. The procedure involved excavation of the top soil and subsoil with a backhoe to an approved depth which is at least 36" below the surface and in other instances as deep as 5 feet below the surface. A 12" hole was excavated into this receiving material, the water poured in, and the test run in accordance with the State Standards. The findings indicate that subsurface disposal systems can be constructed on each lot. Since all of the septic systems will be constructed in accordance with the State Sanitary Code, there shall be no negative impact from these . systems on the ground water or the surface water. The States Sanitary Code that no pollution will occur as long as the design and construction is done witin their standards. Subsurface water quality will thus not be negatively affected by this development. TOWN SERVICES It is anticipated that 18 cars will be owned within this project, as 9 single family homes are proposed to be constructed within the development. The circulation flow is straight forward, with access to Boston Street being only through the one means of egress, available from the new roadway, onto Boston Street. Because of the location of the homes within the development , the driveways from the two lots with fronts on Boston Street will access the proposed roadway, rather that directly onto Boston Street itself. The intersection is very close to Sao, and is considered safely designed with plenty of sight distance'in the North and South'direetions. In fact , the location of the roadway as it enters onto Boston Street was set with the Town; Highway Surveyor, to insure a maximum amount of visibility to the North. This was even done with the consideration that a roadway placed further South on the property would allow for the construction of a Form A lot MERRIMACX ENGINEERING, 5ERVICES INC • 66 PARK STREET • ANDOVER, MASSACHUSETTS 01810 7 immediately, rather than when the roadway servicing the subdivision was under construction. Based on national studies, and information available from the Institute of Traffic Engineers, approximately 8 trips per day per household can be expected in a single family type development. Thetefore, it is anticipated that 72 trips will be generated at the intersection of Boston 'Street and the proposed roadway from this development. An additional 72 trips will most likely occur down Boston Street to Route 114, as that is the principal service road to Boston Street. Route 114 is a major arterial collector, and is also known as Salem Turnpike. Currently, Route 114 has excess capacity to handle additional flows placed by feeder roads to it. The capacity of Boston Street will not be impaired by the construction of this development, as the traffic flow on Boston Street is relatively light. All of the vehicles which will be in and out of the development will be serviced, with either garages or driveways which will be constructed on each lot. No on street parking is anticipated for this project, nor' shall be provided by the developer. The roadway will be fully accessible to police and fire vehicles. The cul-de-sac at the end of the roadway has been designed to allow a fire truck to turn a�rouhd. ' Th ifM* 'oT"the street will be such that It vi-11 not conflict with any streets which are currently named within the Town of North Andover. The street name is subject to approval of the Police and Fire Chief. During construction of the subdivision and the roadway the Police Department and Fire Department will be fully briefed on the activity taking place so as to provide emergency access at all times to the development while under construction. The roadway design has been done in full accordance with the Town of North Andover, Department of Public Works requirement. Included within these specifications are design of a closed drainage system which includes catch basins that have sumps which must be maintained on a periodic basis by the Public Works Department. In addition, pipe lines which carry the drainage flow from the catch basin to the drain man holes and ultimately the streams msut be cleaned and maintained periodically by the Public Works Department. Further, since the Town will have constructed within the roadway a public water main system, it will be necessary for the Public Works Department and the Water Department to maintain this water system. At the same time, it will become necessary for the developer to construct a water main system on Boston Street onto Grey Street. The Department of Public 'Works will maintain this portion of the water system. The developer will be paving Boston Street in the area of water main construction, and therefore, the Public Works Department will monitor this construction and ultimately maintain the pavement which is put in place. Apparently, the Town maintains a public grammar school and high school system, and the maximum amount of children which will be generated by this development should not exceed 1 child per household, or 9 children in total. Since the population of students within the community is declining on a per capita basis , it is the opinion of the developer that any additional children generated by this development can be absorbed by the school system. Further, it should be pointed out that in many cases residents of this development will be residents that were transplanted from one section of the community to this MERRIMACK ENGINEERING SERVICES IN( • 66 PARK STREET 0 ANDOVER. MA55ACHUSETTS 01810 8 section of the community. Therefore, it might be that no new citizens who were not already citizens of the Town will reside in this development. Therefore, it is possible that no impact upon the school system will be felt with this project. Since Town water will be supplied to this development, there will be &-minor"impaat on the maintenance budget of the Water Department itself as it must service the pipe line contained within the project. In addition, it will be necessary for the Water Department to maintain and service the water main which is extended down Boston Street to service the project. Further, since ample supply exists within the Town itself, and the demand from these homes will be only 3,000 gallons of water per day, no negative impacts upon the Town water system should be generated. Further, the Town will receive an increase revenue to the Water Department budget as a result of sales of water to other homes located along Boston Street which will have a distribution system constructed in front of them, by the developer, at no cost to the community. Since septic systems are being provided on each of the lots, no impact on the Town sewer system is anticipated to occur from this project. GEMRAL 1 lPi4CT No negative impacts from this development are anticipated onto the Town of North Andover. Any impacts which in the judgment of Town Officials might be considered negative would certainly be offset by the amount of tax revenue which will be generated by this development to the Town. Currently, the parcel is taxed as vacant unimproved land and after development this will be taxed as individual house lots. Further, all of the homes will have a value in excess of $150,000, based upon the standard type of construction which has taken place in the Town to date. Since the brook does not run into the water supply of the Town of North Andover, no negative impact upon the watershed area is anticipated. Since this area is not significant for flood control to the overall Town area, no negative impacts are expected to result to flood Control in this area of the community. Additionally, construction of this development will not impair the integrity of any existing streets or ways , or the health, safety or welfare of any of the abutters.
