Adding to the foot- print of the building is a family room of 18'x 26' with deck; and razing of the existing garage to construct on the same foot-print new garage and bedrooms above. Portion of construction is within the 100 feet buffer zone of the delineated wetland based on hydric soil. The proposed construction is 93 feet from the flagged wetland (BVW—Bordering Vegetated Wetland). The land area of the site is about an acre. JURISDICTION: The subject property is approximately 2000 feet from the Lake Cochichewick, and is within the delineated watershed boundary of the lake. This lake is the Town's sole source of public drinking water supply. Therefore, the property comes under the jurisdiction of Watershed Protection Division of the North Andover Zoning By- Law; Section 4.136 (2) B. (i) "General Zone". Exhibit A presents the property and the Watershed boundary. In addition, the property is within the 100 feet zone on the water resources area protected under the Wetland Protection Act, MGL Ch. 131, Section 40. Due to wetlands, the property comes within the "4.136 (3)Zone (c): Non-Disturbance Buffer Zone"; and this requires a Special Permit by the Special Permit Granting Authority (SPGA), this authority under Zoning Bylaw is the Town's Planning Board. This application for Special Permit is being submitted to be in Compliance with the "Non-Disturbance Buffer Zone". The following presents the Written Documentation needed to obtaining a Watershed Special Permit (the numbered items refer to the sequence of items in the instructions given in the application package): 1. Encouraging the most appropriate use of land; The site is in a residential zone, and the proposed project is in accordance with the typical requirements of a residential area, and is designed in such way the project will have minimum disturbance to the existing site, the neighborhood and the water resources area. 2. Prevent Over-crowding of land; The proposed addition is within the percentage of gross floor area allowed under the "Non-Disturbance Buffer Zone" special Permit guidelines, and the designed project will result in good appearance, and will not over-crowd the land. 3. Conserving the value of land and buildings; Because of the monetary value added to the property, this will enhance the value of the property and the surrounding buildings and land, and also diligent up-keep of the property and yard will provide an aesthetically pleasing environment. 4. Lessening congestion of traffic; This project will not increase traffic congestion, since there will be no increase in the number of vehicle or vehicle trips due to the proposed building expansion. 5. Preventing undue concentration of population; The existing building will still remain a single-family residence and there will be no increase in the population except an addition of one person, that is, petitioner's aged mother who needs help. 6. Providing adequate light and air; There will be no adverse impact to current background of air and light for all level of the building. 7. Reducing the hazards from fire and other danger, There will be no increase in hazard levels from fire or other dangers. The proposed garage will have 5/8" one hour fire rated gypsum board on ceiling and on all sides. In addition, the building is readily accessible to the Town's fire fighting equipments, and additions will comply with the smoke detectors and carbon-monoxide alarms. 8. Assisting in the economical provision of transportation, water, seiverage, schools,parks, and other public facilities; This project will not impact on the above noted public facilities or utilities. The project will connect the building sewer to the Town sewer, and there will be positive economic benefit to the Town by paying sewer use charges. 9. Controlling the use of bodies of water, including watercourses; This project will not have a negative impact on present uses of the Lake or tributaries. Roof runoff from the proposed structures is discharged into the ground, that is, clean roof runoff is not mixed with the surface and the groundwater quality is not impacted. 10. Reducing the probability of losses resulting from floods; and The applicant is proposing to install,a drywell for the proposed construction, that is, for the garage and family room. A 100 year storm event is considered for the calculating roof runoff volume, resulting in a storage volume of 1274 gallons. And the site is not in the 100-year flood plain. 11. Reserving and increasing the amenities of the Tmvn; This project will increase the amenities of the town through an improvement to the property and additional tax revenue due to new construction assessment. Additional Documentation A. Written certification by a registered Professional Engineer, or other scientist educated in and possessing extensive experience in the science of hydrology and hydrogeology, stating that there will not be any significant of the quality or quantity of water in or entering Lake Cochichewick. The proposed site work presented to the Board will not have a negative impact to the Lake Cochichewick's watershed area. There will be an improvement in the groundwater entering the lake due to sewer connection and decommissioning the septic system; and also roof runoff is made to enter the groundwater directly, designed for 100-year storm event. There is no change in the site grading, and existing conditions will be retained. See enclosed computations. A report from EcoTec is enclosed which presents the wetland delineation work. B. Proof that there is no reasonable alternative location outside the Non- Disturbance Buffer Zones,for any discharge, structure, or activity, associated with the proposed use to occur. Due to the configuration of the existing, new family is in the best location in the back, and the garage will be rebuilt at the same location. This also helps to retain the present set back distances. C. Evidence of approval by the Mass. DEP of any industrial wastewater treatment or disposal system or any wastewater treatment of system fifteen (15,000) gallons per day. This item is not applicable to this site. D. Evidence that all on-site operations including, but not limited to, construction, waste water disposal,fertilizer applications and septic systems will not create concentrations of Nitrogen in groundwater, greater than the Federal limit at the down gradient property boundary. Existing building is on septic system, and this system abandoned by connecting the building to the Town sewer system, and there will be a decrease in nitrogen, loading to the groundwater, a beneficial impact. There will not be any increase in the application of fertilizer, if fertilizer applied at all. E. Projections of down gradient concentrations of nitrogen,phosphorus and other chemicals at property boundaries and other locations deemed pertinent by the .SPCA. There will be no down-gradient concentration of nitrogen and phosphorus due to the proposed site work.

ENVIRONMENTAL CONSULTING SERVICES 102 Grove Street Worcester, MA 01605-2629 508-752-9666 -Fax: 508-752-9494 June 11, 2010 Mrs. Gretchen Trafton 137 Salem Street North Andover, MA 01845 RE: Wetland Resource Evaluation, 137 Salem Street, North Andover, Massachusetts Dear Mrs. Trafton: On June 11, 2010, EcoTec, Inc. inspected the above-referenced property for the presence of wetland resources as defined by: (1) the Massachusetts Wetlands Protection Act (M.G.L. Ch. 131, § 40; the "Act") and its implementing regulations (310 CMR 10.00 et seq.; the "Regulations"); (2) the Town of North Andover Wetlands Protection Bylaw (the "Bylaw") and the Town of North Andover Wetlands Protection Regulations (the"Bylaw Regulations"); and (3) the U.S. Clean Water Act (i.e., Section 404 and 401 wetlands). John P. Rockwood, Ph.D., PWS conducted the inspection. The subject site consists of an approximately one acre parcel of land located to the southwest of Salem Street in central North Andover, Massachusetts. The site is largely developed with a single-family house with a deck, paved driveway, patio, wooden retaining walls, post and rail and metal fencing, a play house, swing set, sand box, trampoline, and associated lawn and landscaping. The site slopes gradually to moderately to the southwest. The wetland resources observed on and near the site are described below. Methodology The site was inspected, and areas suspected to qualify as wetland resources were identified. The boundary of Bordering Vegetated Wetlands was delineated in the field in accordance with the definition set forth in the regulations at 310 CMR 10.55(2)(c). Section 10.55(2)(c) states that "The boundary of Bordering Vegetated Wetlands is the line within which 50% or more of the vegetational community consists of wetland indicator plants and saturated or inundated conditions exist." The methodology used to delineate Bordering Vegetated Wetlands is further described in: (1) the BVW Policy "BVW- Bordering Vegetated Wetlands Delineation Criteria and Methodology," issued March 1, 1995; and (2) "Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act: A Handbook," produced by the Massachusetts Department of Environmental Protection, dated March 1995. Bylaw and federal wetlands were presumed to have boundaries conterminous with the delineated Bordering Vegetated Wetlands. One set of DEP Bordering Vegetated Wetland Delineation Field Data Forms completed for observation plots located in the wetlands and uplands at flag A6 is attached. As the entire wetland boundary is located within a recently mowed lawn area, the wetland boundary was based largely upon the extent of saturated hydric soils. It should be noted that the Mrs. Gretchen Trafton June 11, 2009 Page 2. mowing of lawns is not subject to jurisdiction under 310 CMR 10.00. The table below provides the Flag Numbers, Flag Type, and Wetland Types and Locations for the delineated wetland resources. Flag Numbers Flag Ty e Wetland Types and Locations Start A I to A 14 Stop Blue Pin Flags Northeastern boundary of Bordering Vegetated Wetlands located within the maintained lawn in the southwestern portion of the site and off-site to the southwest that is associated with a small "pond" and intermittent stream located off-site to the southwest. Findings Wetland A (i.e., flags Al to A14) consists of wetland lawn and forested swamp located in the southwestern portion of the site and off-site to the southwest that is associated with a small "pond" and an intermittent stream located off-site to the southwest. An approximately five- to 20-foot-wide band of lawn with saturated hydric soils was included within the wetland that was delineated under this evaluation. Plant species observed within the forested swamp include red maple (Ater rubrum), willow (Salix sp.), white ash (Fraxinus americana), and American elm (Ulnms amefzcana) trees and/or saplings; poison ivy (Toxicodendron radicans) climbing woody vines; multiflora rose (Rosa nurltiflora) and arrow-wood (Viburnum dentatunu) shrubs; and bristly blackberry (Rebus hispidns), cinnamon fern (Osnnanda cinnamomea), royal fern (Osmuinda regalis), sensitive fern (Onoclea sensibilis), spinulose woodfern (Dryopteris spinulosa), skunk-cabbage (Symplocarpus foetidus), spotted touch-me-not (Impatiens capensis), grasses (Gramineae sp.), purple loosestrife (Lythrum salicaria), golden-rods (Solidago sp.), spotted Joe-pye-weed (Eupatoriadelphus maculates), and sphagnum moss (sphagnum sp.) ground cover. Evidence of wetland hydrology, including hydric soils, high groundwater, saturated soils, and pore linings, was observed within the delineated wetland. This vegetated wetland borders an intermittent stream; accordingly, the vegetated wetlands would be regulated as Bordering Vegetated Wetlands under the Regulations and Bylaw/Bylaw Regulations. The small "pond" could be regulated as an Ephemeral Pool (assuming it meets the requisite biological criteria which were not assessed during this evaluation) under the Bylaw/Bylaw Regulations. A 100-foot Buffer Zone extends horizontally outward from the edge of Bordering Vegetated Wetlands under the Regulations and Bylaw/Bylaw Regulations. Bordering Land Subject to Flooding is an area that floods due to a rise in floodwaters from a bordering waterway or water body. Where flood studies have been completed, the boundary of Bordering Land Subject to Flooding is based upon flood profile data prepared by the National Flood Insurance Program. Section 10.57(2)(a)3. states that "The boundary of Bordering Land Subject to Flooding is the estimated maximum lateral extent of flood water which will theoretically result from the statistical 100-year frequency storm." Based upon a review of the Flood Insurance Rate Map ("FIRM"), Community Panel 250098 0006 C, dated June 2, 1993 (attached), the site is located within Other Areas: Zone X, which is defined as areas located outside of the 500-year floodplain. Given the lack of a nearby mapped Zone A (i.e., 100-year floodplain) or a significant water body or waterway, Bordering Land Subject to Flooding would EcoTec, Inc Mrs. Gretchen Trafton June 11, 2009 Page 3. not occur on the site. Bordering Land Subject to Flooding does not have a 100-foot Buffer Zone under the Regulations or Bylaw/Bylaw Regulations. The Massachusetts Rivers Protection Act amended the Act to establish an additional wetland resource area: Riverfront Area. Based upon a review of the current USGS Map (i.e., Lawrence Quadrangle, dated 1987, attached) and observations made during the site inspection, a stream that is shown as intermittent on the USGS Map is located off-site to the southwest. Based upon StreamStats, the watershed area for this stream to a point over 200 feet downstream of the site was determined to be 0.045 square miles (see attached Massachusetts StreamStats Basin Characteristics Report). As such, the stream would be designated intermittent under the Regulations. Furthermore, based upon a review of the current USGS Map and observations made during the site inspection, there are no other mapped or significant unmapped streams located within 200 feet of the site. The intermittent stream to the southwest of the site is not one of the streams listed in the Bylaw Regulations as having an associated Riverfront Area under the Bylaw/Bylaw Regulations. Accordingly, based upon the above, Riverfront Area under the Act/Regulations and Bylaw/Bylaw Regulations would not occur on the site. Riverfront Area does not have a Buffer Zone under the Act/Regulations or Bylaw/Bylaw Regulations. The Regulations require that no project may be permitted that will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified by procedures set forth at 310 CMR 10.59. Based upon a review of the Massachusetts Natural Heritage Atlas, 13`h edition, Priority Habitats and Estimated Habitats, South Groveland Quadrangle, valid from October 1, 2008, there are no Estimated Habitats [for use with the Act and Regulations (3 10 CMR 10.00 et seq.)], Priority Habitats [for use with Massachusetts Endangered Species Act (M.G.L. Ch. 131A; "MESA") and MESA Regulations (321 CMR 10.00 et seq.)], or Certified Vernal Pools on or in the immediate vicinity of the site. A copy of this map is attached. The reader should be aware that the regulatory authority for determining wetland jurisdiction rests with local, state, and federal authorities.

Rockwood has been a Senior Environmental Scientist with Eco Tec, Inc since October 1999. Prior to joining EcoTcc, Dr. Rockwood was a Chief Environmental Scientist at Sanford Ecological Services, Inc. of Southborough, MA from September 1990 to October 1999. Dr. Rockwood was certified in August 2002 and recertified in March 2008 as a Professional Wetland Scientist (PWS) by the Society of Wetland Scientists, the leading professional organization in the field. His project experience includes wetland resource evaluation, delineation, and permitting at the local, state, and federal levels; wildlife habitat evaluation; pond and stream evaluation; vernal pool evaluation, certification, construction/replication, and monitoring; endangered species habitat and impact assessment; wetland replacement, replication, and restoration area design, construction, and monitoring; and expert testimony preparation. He has served as a consultant to municipalities, conservation commissions, the development community, engineering and survey firms, industry, and citizen's groups. He has managed and participated in a variety of wetlands related projects ranging in scope from single-family house lots to subdivisions, commercial developments,golf courses,a water park, and regional malls. He has assessed the potential impacts of stormwater runoff, landfill leachate, and hazardous waste sites on endangered vertebrate and/or invertebrate species, including the spotted turtle, marbled salamander, wood turtle, tri angle floater mussel, and squawfoot mussel, and has conducted and/or directed surveys, delineated actual habitat, and/or developed mitigation strategies necessary to protect endangered vertebrate, invertebrate, and plant species, including the spotted turtle, eastern box turtle, wood turtle, marbled salamander, four-toed salamander, ringed boghaunter dragonfly, eastern elderberry long-horned beetle, Mystic Valley amphipod, and threadfoot, and their habitats from proposed development related impacts. He has participated in preconstruction sweeps for spotted turtle, wood turtle, and eastern box turtle. He has conducted environmental impact assessments, and has prepared MEPA documentation related to an office park,a train station,a water park,a residential subdivision,a landfill,and a regional mall.Dr. Rockwood also has extensive experience in the area of environmental site assessment related to possible oil and/or hazardous material contamination. He has conducted numerous environmental assessments, several including subsurface investigations, for sites located in Massachusetts,and has conducted preliminary environmental assessments for properties located in New York,New Hampshire,and Rhode Island. He has conducted ecological risk assessments (i.e., Stage I Environmental Screenings and Stage II Environmental Risk Characterizations)for a number of disposal sites in Massachusetts under the MCP,including several disposal sites that had the potential to affect state listed vertebrate and invertebrate species, and has utilized the EPA Rapid Bioassessment Protocol for macroinvertebrates to assess potential impacts of disposal sites on streams and rivers. He has served as the environmental contractor to the Franklin Consolidated Office of the Federal Deposit Insurance Corporation (FDIC-FCO) for 16 months. At the FDIC,he reviewed environmental reports,prepared scopes-of-work for site assessments,and provided technical advice to FDIC employees related to environmentally compromised assets. Dr. Rockwood has designed,conducted, and evaluated numerous surface water and groundwater monitoring programs. His prior research includes a laboratory study of the effects of low pH and aluminum on dragonfly nymphs and a field survey of the impact of chlorinated sewerage effluent of algal periphyton community dynamics. Dr. Rockwood is the co-author of a text book in aquatic biology,and is the principal author of three peer-reviewed research publications in the Geld of aquatic toxicology that address the effect of low pl-1 and aluminum on nymphs of the dragonfly Libellula julia. Dr. Rockwood has served as the Assistant Editor of the AMWS Newsletter from May 2003 to November 2004,and as the Editor of the AMWS Newsletter from November 2004 to the present.
