NEVE y °f �°� d r s bN�iL ' ' ROCKY BROOK ESTATES STATEMENT OF ENVIRONMENTAL IMPACT ' Please refer to the Definitive Subdivision Plans and the Hydrological Analysis Plans attached to aid in the review of ' this statement: A. Plan Information ' 1 . Present and proposed topography are shown at a two foot contour interval. A graphic drainage configuration is shown on Hydrologic Drawings H-1 through H-4 attached with an associated Hydrologic Report. 2 . The site is completely moderately wooded with little ' underbrush. The surface of the ground is sloping from north to south down to the watershed of Mosquito Brook. There are no outstanding tree groupings on the site which should be preserved. The wetland associated with Mosquito ' Brook is significant and does contain botanical features and wildlife habitat potential which should be protected during construction. All wetlands have been delineated ' by I .E.P. Environmental Scientists and located and plotted on Plans by Neve Associates. ' 3 . Most of the soil in the area being subdivided has been observed by digging several deep holes to identify the soil structure and permability. See Perc Test results attached. All tests were witnessed by the North Andover ' Board of Health agent. 4 . Soil types and Hydrologic Soil Groups are shown on ' the Hydrologic Drawings and included in the report. B. Physical Environment ' The general characteristic of the site is ' rural. The abutting land to the south and east is undeveloped. The land to the north along Tanglewood Lane, part of Wintergreen ' Estates Subdivision, will contain single family homes. The site is physically comprised of gentle sloping land ' to a moderate bank leading down to the wetlands associated with Mosquito Brook. The upland is a very suitable candidate for single family development. C. Surface, Water and Soils 1 . There are wetlands to the south and southeast of the ' proposed development. The rear of Lots 12, 14 , 18 and 19 contain wetlands which will not be disturbed for the construction of the dwellings. The wetland between Lots ' 15 and 16 shall be used as a Detention Basin to control the peak rate of runoff leaving the site. The surface runoff characteristics are shown on Sheet H-1 through H- 4 . The wetlands shown will be the receiving bodies for ' pre and post development runoff. With the use of the Detention Basin there will be no increase in the peakrate of runoff leaving the site. ' 2 . During the construction the developer will install a row of staked hay bales in the location as shown on Sheet H-1 and H-2 to control sedimentation and erosion from entering the wetlands . A triple row of staked hay bales backed up by a filter fabric fence shall be installed perpendicular to the inlet outfill of the Detention Basin t as shown and at all cross culverts. This system shall be maintained throughout the duration of construction. As a secondary provision to control sediments from entering ' the significant wetlands associated with Mosquito Brook an inverted elbow shall be installed at the inlet of the outlet pipe leaving the Basin. This elbow shall be made of 12" diameter corrugated metal pipe with 4 one inch ' diameter holes drilled at elevation 112 and 114 respectively with a baffled top at elevation equal to 116 .00 . ' 3 . The detention basin has been designed to detain the increase in the rate of runoff during a 10 year and 100 year, type II, storm event. The basin shall be a permanent mitigation device. The basic should not require regular ' annual maintenance since we do not anticipate the post development sedimentation to be of significant volume. After several years, however, the basin will require a surface cleaning. The proposed grading is shown on Sheets 4 and 5 in order ' to construct the roadway and appurtenances . Approximately 50% of the lot areas will be disturbed to construct the homes, drives and install proper landscaping features. No large cuts or fills are required to develop the site. ' No waivers for the construction of the roadway is required, i.e. , slope, grade. ' 4 . Sewage Disposal shall be provided by conventional subsurface means. Each dwelling shall have its own septic system. Each system shall be designed in strict accordance ' with the State Environmental Code (Title V) and the local Board of Health Regulations. No system shall have an impact on any surface water, soils, or vegetation existing on the site. ' D. Subsurface Conditions ' The soils on the site are considered moderately well drained. ( See Soil portion of Hydrology Report) . The ground where tested was comprised of sandy-glacial soils. Groundwater will not pose a limitation during construction. Since all sewage disposal systems will be desgined in strict accordance with the health regulations, the impact on the ' quality of subsurface water is minimized. ' E. Town Services ' Rocky Brook shall be about 1975 feet in length and will access and engress onto Tanglewood Lane to the north of the site. We propose 19 additional lots which will generate 228 vehicle trips per day. This quantity will pose no ' impact on Tanglewood Lane. ultimately, the land to the east, currently owned by Farr, shall be developed extending Rocky Brook Road to Main Street in the Town of Boxford. ' The road will have town water and town drainage. Water will temporarily dead end. Drainage all flows into the ' brook watershed. The drainage system is typical of Town roads, and will be maintained by the Highway Department. t The subdivision will impact the DPW and Highway Department work load and maintenance requirements. There is no unusual service or maintenance problems associated with the proposed new roadway. ' The subdivision has the potential of generating 38 children which primarily will attend public schools. No indication ' was made by the School officials whether this ,number will pose a significant problem to the school system. General Impact We feel that this subdivision has been intelligently designed. Provisions for future extension to Main Street ' in Boxford have been made. The wetlands on the property have been protected by this design. The development has been designed to .have no increase in the peak rate of runoff leaving the site, post development.• The soils are suitable for disposal of sanitary wastes and all dwellings will be served by Town water. 1 ' ROCKY BROOK ESTATES Perc Test September 3, 41 & 9, 1986 ' 1 .

The site drains in a southerly and westerly direction to the ' wetlands adjoining Mosquito Brook. The site is comprised of forest areas and shrub areas with poorly drained soils. Classification of soils were determined by the Soil Conservation Soil Survey Maps of 1981. The purpose of this analysis has been to design structural ' onsite drainage which complies with Planning Board criteria while limiting off-site runoff discharge to below existing rates . The DRAINCALC Computer Model, an intensive flood routing program which incorporates SCS methods and standard hydraulic ' relationships, has been used to model existing and post-development hydrology and to size and design the storm drain system. The model develops hydrographs for each ' subcatchment area within the watersheds, routes them through channel reaches, pipes and detention areas with controlled outlets and integrates them to generate composite hydrographs . The model also prints out summaries of -subcatchment input data ' and tabulations of detention (storage) pond inflow, stage and storage volume at small time increments during the modelled storms . The storm drainage pipe network was designed for a 10 year storm event. The culverts carrying existing water courses under proposed roadways were designed for a 100 year storm event. This criteria is required according to the Town ' of North Andover Subdivision Rules and Regulations. This hydrologic analysis is based on the combined run-off leaving the site and draining towards the wetlands to the south and west of the property. The following table shows a comparison of the existing and post-development discharge rates. The increase in run-off has been mitigated with a detention pond.

The length of the dead end roadway exceeds the maximum allowed under the rules and regulations of the Planning Board and no provision is allowed for roadway continuity to other land that will permit the extension of the roadway to connect to other streets and roadway. Because the proposed dead end road is so long (about 2000 ft. ) and is situated at the very edge of Town, the Planning Board has concerns regarding traffic flow, serviceability and emergency access. Accordingly, no construction shall commence on this project until the applicant provides sufficient documentation concerning alternatives to the current road layout and the likelihood of the extension of the roadway to the abutting property within a reasonable time. When this information is received, the Planning Board will make a final determination whether to grant a waiver regarding the dead end roadway and/or establish additional conditions regarding the length of the dead end and the possible extension of the roadway to abutting property. 36 . The Planning Board is of the opinion that many of the lots specifically 18 , 19 and 14 are not buildable lots either because of extensive wetland and floodplain areas, Board of Health restrictions or zoning violations. It is the developers responsibility to demonstrate otherwise on the plans, or through a site plan where necessary. 37 . Plans for water main looping shall be provided to the Planning Board for approval prior to endorsement. 38 . The insertion of a new roadway across lot 22 of Wintergreen Estates will require a Modification (under Chapter 41, Sec. 81W) of the Wintergreen Estates subdivision. This modification will entail a new (i.e. revised) application and Public Hearing for the Wintergreen Estates subdivision. Consequently, no construction will be allowed on the Rocky Brook subdivision until the modification of the Wintergreen Estates subdivision has been approved by the Planning Board. 39 . In order to provide for the common welfare, convenience and safety of future inhabitants of the subdivision, and to preserve important site features, the applicant shall submit to the Planning Board for its approval an appropriate plan which provides for open space for parks and/or recreation. 40 . The applicant shall submit an appropriate plan to the Planning Board to preserve (through a conservation easement or other development restriction) the existing walking path that extends through the subdivision. 41. Prior to endorsement, the applicant shall submit to the Planning Board for its approval an appropriate plan for phasing the construction of the subdivision. 42. The developer will provide written documentation to the Planning Board and staff that he has permission, without liability to the Town of North Andover , to cross the subdivision known as Wintergreen Estates in order to gain access/egress from the proposed Rocky Brook Subdivision. 43. In the event Cluster zoning is passed at the Annual Town Meeting this parcel would become eligible and the Planning Board would encourage such application. cc: Highway Surveyor Board of Public Works Tree Department NACC Building Inspector Health Department Assessor Police Chief Fire Chief Applicant Engineer File RECEIVED DANIEL LONG TOWN CLERK WORTH Awp0VER FORM B APR Z5 APPLICAT�ION�FOR APPROVAL OF A PRELIMINARY PLAN i2JG �S , 19A To the Planning Board of the Town-of North Andover: i The undersigned, being the applicant as defined under Chapter lulu Section 81—L9 for approval of a proposed subdivision shown on a plan entitled IMAsAy C;f;ZWv/C,(4 a4,v Ree4e Ssr 7Zs By .tom d &jadated 4PX&- Z3 , 19 _ being land bounded as follows: mac% F hereby subunits said plan as a PRELIMINARY subdivision plan in accordance with the Rules and Regulations of the North Andover Planning Board and makes application to the Board for approval of said plan. ew-2411 Rf 2�7 X&- 2aa e Title reference: North Essex Deeds, Book&//, PageM; or Certificate of Title No, Registration Book j Per.; or Others Applicant's signature.
