In general, the site is developed with an existing two story commercial building with associated parking and landscaped grounds bounded by a ' forested coniferous/deciduous hillside to the west. Topography is generally rolling with an overall slope to the east. The wetland is comprised of an intermittent swale located to the west and southwest of the proposed addition. This channel originates at a groundwater seep and flows ' northerly, through a red maple shrub swamp and ultimately dispersing into a red maple swale which discharges surface flow to the east. This swale extends to the east, towards the intersection of Willow Street South Extension and Flagship Drive and continues off-site to the east beneath Willow Street South Extension. Fugro utilized a multiparameter methodology to confirm the state and federal jurisdictional ' wetlands, and reviewed soil characteristics in the field as well as literature review of the Soil Conservation Service maps. Soil characteristics were examined in the wetlands and adjacent uplands. Field evaluations were utilized in conjunction with the Soil Conservation Service Soil ' Survey of Essex County,Northern Part published in February, 1981 (SCS Survey). According to Sheet 36 of the SCS Survey, the soils within the aforementioned wetland are classified as ' Whitman and as very poorly drained. Upland soils were mapped by SCS as Montauk-well drained and Woodbridge-moderately well drained. Field evaluations confirmed the SCS Survey findings within the wetlands and the adjacent upland. ' As defined under the Massachusetts Wetlands Protection Act (MWPA) (MGL Ch. 131, s.40), its Regulations (310 CMR 10.00), and the North Andover Wetlands Protection Bylaw and Wetlands ' Regulations two resource areas are present: Bank (310 CMR 10.54), and Bordering Vegetated Wetlands (BVW) (310 CMR 10.55). According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map for North Andover, Panel # 250098 0006C and 0008C, no ' portion of the 100 year flood plain is located within or adjacent to the site. The Massachusetts Natural Heritage and Endangered Species Program's (Program) Atlas of Estimated Habitats of Rare Wetland Wildlife (1995/96 Edition) has not mapped any known rare wetland wildlife habitat on this parcel. Fugro sent a letter (November 14, 1996) to the Program ' requesting a review of their records.for the entire site (i.e., upland and wetlands) for the presence of protected (i.e., rare, threatened, endangered, special concern) wildlife and plant species and/or critical habitats (See Appendices). According to the Massachusetts Natural Heritage Estimated ' Habitats for Rare Wetlands Wildlife, 1995-1996 Edition, South Groveland Quadrant there are no rare wetlands wildlife estimated habitats documented on the site. ' S-1 Notice of Intent• 165 Flagship Drive, North Andover,MA•November 18, 1996 5.2 Wetland Delineation Jurisdictional resource areas were delineated by a wetland scientist from Fugro in October 1996. ' The wetland boundaries were reviewed in accordance with Section 404 of the Clean Water Act, Massachusetts Wetland Protection Act (MGL Ch. 131, s. 40), its Regulations (310 CMR 10.00), ' and the North Andover Wetlands Protection Bylaw and Wetlands Regulations. The edges of freshwater vegetated wetland were flagged in the field using pink plastic surveyors tape labeled numerically. Wetland flags were subsequently surveyed as shown on the site plan depicting wetland resource areas (see Grading and Utilities Plan). Vegetated wetland delineations were also reviewed pursuant to Section 404 of the Clean Water Act in accordance with the Corps of Engineers Wetland Delineation Manual (1987) and relevant Corps of Engineers-New England Division wetland delineation policies. 5.3 Wetland Resource Areas The BVW associated with the intermittent stream and red maple swamp are dominated by a mature canopy and shrub species. The intermittent stream channel discharges flow to the north. ' A mosaic of braided stream channels and sheet flow discharge into a broad swale that conveys flow to the east, towards the intersection of Flagship Drive and Willow Street South Extension, and along the northern property boundary. The canopy is dominated by red maple (Ater rubrum) with swamp white oak (Quercus bicolor), ' red oak (Quercus rubra), and eastern white pine (Pinus strobus) co-dominating. The shrub layer is well established. Dominant shrubs include, northern arrowwood (Viburnum recognitum), highbush blueberry (Vaccinium corymbosum), sweet pepperbush (Clethra alnifolia), and swamp ' azalea (Rhododendron viscosum). Herbaceous species include cinnamon fern (Osmunda cinnamomea), jewelweed (Impatiens capensis), poison ivy (Toxicodendron radicans), and sphagnum moss (Sphagnum sp.). ' 5.3.1 Jurisdictional Wetland Resource Areas ' Jurisdictional resource areas were identified and demarcated in the selected portion of the site in accordance with the Massachusetts Wetlands Protection Act (M.G.L. c. 131, s. 40) and its Regulations promulgated at 310 CMR 10.00, and the North Andover Wetlands Bylaw. As ' indicated previously, the edge of the BVW(310 CMR 10.55) was demarcated by pink surveyor's flagging tape numerically labeled 1-9. The eastern boundary was demarcated from the southwestern corner of the existing building to the southwest. The wetland is located just above ' the top of the slope which coincides with the edge of the maintained lawn hillside. The boundary parallels a stone wall between flags 4 and 6 then diverges to the southwest, along the toe of a ' moderate slope, to Flag 9 "End". Wetland flags are illustrated on the "Grading and Utilities Plan" prepared by MHF Design Consultants, Inc., dated October 29, 1996. ' S-2 Notice ojlntent•165 Flagship Drive,North Andover,MA•November 18, 1996 ' According to a letter prepared for Channel Building Company from H.W. Moore Associates,Inc. (dated June 24, 1986) the 100 year flood elevation was determined as 237, Mean Sea Level ;see Appendix B). This elevation was determined as a component of the Willow Street Extension ' Notice of Intent hydrologic evaluation and does not extend into the site. Therefore, the site does not contain any Bordering Land Subject to Flooding (BLSF) which is protected as a resource area. ' S-3 . 1 Proposed Activitiesand Mitigating Measures ' Notice of Intent• 165 Flagship Drive,North Andover, MA•November 18, 1996 6.0 PROPOSED ACTIVITIES AND MITIGATING MEASURES 6.1 Proposed Activities Relative to Jurisdictional Wetland Areas ' N w wetlands. in 0 work is proposed wrtlun any local, state, or federal jurisdictional elands. Also, compliance with the North Andover Wetlands Bylaw and its regulations, no work is proposed within 25 feet of the wetland boundary. - 6.1.1 Compliance Evaluation As indicated previously, all proposed activities on the site meet the performance standards for Wetland Resource Areas of the Act and Regulations. No BVW, Land Under Watervay (LUWW), BLSF, Isolated Land Subject to Flooding (ILSF) or Bank will be directly altered for the proposed construction on the site. ' 6.2 Proposed Activities Within the Buffer Zone of Wetlands ' Work within 100-foot buffer zone of BVW includes a portion of the building and associated parking, drainage swales, portions of the access roadway, grading, and BMPs. As required by the North Andover Wetlands Bylaw, the project has been designed to provide a 50-foot no- construction setback and a 25-foot no disturbance setback along the entire wetland boundary. In accordance with the local by-law, no structures are proposed within 50 feet of the edge of wetlands. 6.3 Stormwater Runoff Water Quality ' Construction methodology and sequence is proposed to address water quality, erosion protection, and sediment control issues. The design of the proposed drainage system will tie into and utilize the existing stormwater system to insure that the minimum surface water quality standards are met. The existing system of catch basins, manholes, swales, and pipes will direct runoff from the site to the existing outlet in the northeastern corner of the site. Sediment barriers will be installed ' at this outlet prior to any construction activities. Since the proposed site layout will remain below the build out capacity of the parcel, the existing stormwater treatment system for the commercial subdivision will provide sufficient treatment for the additional runoff(see Drainage Analyses and Design submitted under separate cover prepared by MHF). 6.4 Proposed Activities Beyond the 100-foot Buffer Zone Proposed activities beyond the 100 foot buffer zone, include portions of the 19,000 s.f. office ' building addition, associated paved parking, a parking lot runoff drainage ditch, grading, landscaping, and subsurface utilities. The area surrounding the building will be graded and 6-1 ' Notice of Intent• 165 Flagship Drive, North Andover, MA•November 18, 1996 landscaped. A siltation fence and haybale barrier will be installed approximately 25 feet from the wetland boundary which will also act as a visual barrier for the limit of work (see Grading and Utilities Plan). The site layout has been designed to allow for the 50-foot no construction set-back required by the North Andover Wetlands Bylaw. 6.5 Erosion and Sedimentation Control ' Prior to the start of construction, standard erosion and sedimentation controls will be installed between all proposed activities and adjacent wetland resource areas (see Grading and Utilities ' Plan). These controls will be inspected and maintained throughout the duration of construction and site disturbance. Any controls which are not performing as intended will be replaced and/or removed, and any other areas of the site which require additional controls will be addressed. No ' erosion control measures will be removed until all areas are mechanically or vegetatively stabilized. For additional details please see the report entitled"Drainage Analysis and Design for Proposed Addition", dated October 7, 1996 prepared by MHF Design Consultants, Inc.

The proposed project is located in the North Andover Business Park Expansion at 165 Flagship Drive North Andover, Massachusetts. The property, Assessors Map 25 Lot 85, also known as Lot 3 North Andover Business Park Extension, consists of approximately 5.192 acres and contains an existing 2 story metal and masonry building with associated site utilities and structures. ' This project proposes an addition of a±19,295 s.f building and associated site improvements to the existing±31,690 s.f. building. Improvements include access improvements, additional parking, drainage ' and associated grading for the proposed addition. This property is part of the previously approved"Definitive Subdivision Plan, North Andover Business ' Park Extension, Willow Street-Flagship Drive", prepared by Thomas E. Neeve Associates, Inc. Dated December 1, 1989. Part of this plan included an overall, master hydrologic and hydraulic analysis, a stormwater management plan for the development of the park. This analysis confirms that the original master plan of stormwater management is adhered to for the ' proposed addition to the existing building and development of Lot 3. That is to say that the flows and drainage patterns for the proposed development of Lot 3 meet the requirements of the master plan. Drainage patterns are similar and flows are less than anticipated in the master plan of stormwater 1 management for this site and drainage areas. This proposed stormwater management plan utilizes the same methodology as the original master plan of stormwater management in order to develop peak flow rates for design of the proposed drainage system. The design standards of the North Andover Site Plan Regulations require the determination of the 2-yr, 10-yr and 100-yr peak flows for comparison to the master plan, design of the interior site drainage is based on the Rational Method for the 10-yr design storm while the intercepting g-ass lined swales are I desigr_ed to handle the 100-yr peak flows based on the peak flow as developed by the use of the USDA- SCS TR20 computer software. B. Hydrology. The approved original master plan of stormwater management for the "Definitive Subdivision Plan, North Andover Business Park Extension, Willow Street-Flagship Drive" assumed that the proposed lots within ' the development would be significantly developed. The master plan's site area drainage plan indicated. the division of Lots for the business park and the extent of impervious land (buildings, drives and parking areas) associated with each lot. This was done to develop proposed peak flows. Development of the business park is occurring with significantly less area becoming impervious land and 1 thus resulting in lower peak rates of runoff, and therefore, in general compliance with the stormwater management master plan. The direct comparison of the master plan and the Lot 3 as shown in the Definitive Subdivision Plan to the current configuration of Lot 3 and it's actual development is ' somewhat complicated by revisions to lot lines. Lot line revisions were due in part to wetland areas encountered during construction and development of other adjacent properties. This has resulted in the current configuration of Lot 3. The current configuration of Lot 3 is comprised partly of both th-_ ' Difinitive Subdivision Plan's Lot 2 and 3. This can be easily seen by overlaying the current configuration of Lot 3 on the Difinitive Subdivision Plan. Likewise, the following comparision of the current Lot 3 to the Definitive Subdivision Plan can be made by overlaying the current Lot 3 layout and proposed development on the Definitive Subdivision Plan, master plan's site drainage map. Given the preceeding, the following may be determined by this overlay of lot configurations and land uses: Impervious Land Overlay No. Lot 2 and Lot 3 of Definitive Subd. Plan. (Area within Lot 3 145,701 s.f. A with revised property lines) Lot 3 with existing and proposed addition 131,441 s.f. B Net Change (A decrease in the proposed impervious land area): 14,260 s.f. Given the net decrease in impervious land proposed for the same area, the resulting lower weighted runoff curve number, slightly longer times of concentration (due to less flow over paved surfaces and closed drainage systems), it follows that the resultant peak rates of runoff will be lower than those originally approved for the same area. The proposed Lot 3 addition along with the existing development will result in lower peak rates of runoff P P g g P than that which was approved in the Definitive Subdivisions stormwater management master plan. Further, it can be seen that drainage patterns of the stormwater management master plan are retained with the intended flow to the"Central Detention Basin". See Overlay plans A& B, 1"=100'. ' In summary, the proposed peak rates of runoff will be less for Lot 3 with the proposed addition, than to those determined and approved in the "Definitive Subdivision Plan, North Andover Business Park Extension, Willow Street-Flagship Drive". This is due to a net reduction in the proposed impervious land area and the retention of the proposed drainage patterns. 1 C. Hydraulics. The proposed interior drainage system is proposed to connect to the existing drainage system. Design is in accordance with the Drainage Design Criteria and Standards of the Town of North Andover. The 2- yr, 10-yr and 100-yr design storms were utilized to determine the peak rates of runoff for the sizir_g of drainage structures and the analysis of existing structures to determine adequacy. ' Drainage Design Basis: Drainage Design for Interior Site is based on the Rational Method, Q=CIA. ' The following coefficients of runoff are used: Undeveloped Woodland, rolling slope 5-10%, using soil texture clay for a factory of safety, ' C=0.50. Lawn areas, sandy loam, 0-5% slope, C=0.3. Pavements, roof areas or other impervious land, C=0.7-0.95 use C=0.9. Time of Concentration: ' Time of Conc. For swales developed utilizing the USDA-SCS TR55 methods. Time of Conc. For interior drainage system developed utilizing the Seelye Chart (see appendices). Minimum Time of Conc. Is 5 minutes. ' Travel time in the pipe is accounted for in the storm drainage design chart. Rainfa_l Intensity from the Intensity Duration Frequency curves for Boston, Ma. (See appendices). ' Design storm for interior drainage is the 10-yr. Reccurrence interval. Exterior drainage analysis and design utilized the 2, 10 and 100-yr. Reccurrence intervals with the swales designed for the I00-yr.

The May 14, 1997' inspection was conducted in the early growing season„ thnrus the woody vegetation was only partially leafed out and not all the herbaceous species had sprouted. The mature tree canopy along the fringe of the replacement area and those trees saved within the replacement area appeared to all be in good condition, except one white oak ( uercus alba) which had broken off approximately 30 feet high. Since the tree damage is at 30 feet„ ENSR does not believe the damage is associated with the excavation of the replacement area. This damage may have occurred during a winter storm, possibly the April 1 1997 blizzard. Sr aril- n i t >ogra nt �de s pans f6A.,1 ' t w r rnera4tymoist,on the %trface and saturated in the, ,1 a, 'goody wetland vegetation was inventoried and the overall physical condition was documented. A total of twenty-three shrubs and saplings were observed including six red maples ( cer- rubrur ), eight northern arrow-wood (Viburnrnurn reco rniturrr), four highbush blieberry (Vacciniurn cor rrubo, ur ), and five swamp azalea (Rhododendron visceosum). All shrubs and saplings were in good condition at the time of the monitoring evaluation.

In addition„ cinnamon fern (C srr unda cinl7arnomea) fiddle-heads were common throughout the replacement area.. Other herbaceous species including skunk cabbage ( ymplocatpu foetldus), marsh fern (Thelypteris t elypterolde,$), wood anemone (Anemone cone uinquef lia) , and Canada mayflower ( alanther3"/u/"/"d canadense) were scattered along the fringe of the replacement area and characterized as occasional.

An additional monitoring evaluation will be conducted later in the 1997 growing season and a report will be issued to the Conservation Commission at that time, This replacement area complements the adjacent forested wetland habitat and, as it matu9res„ is expected to be a valuable edge habitat component of the overall wetland system.

Andover, NIA Sub: Engineering Review Dear John: Attached for your review are revised site plans and drainage calculations for the above referenced project. These revisions incorporate your review continents :Dated November 27, 1996. The following is our response to your comments which are numbered to corresponc with Your review letter: I. No response required. 2. The soil types on the data sheets have been changed to reflect the appropriate soil type, but the original runoff value used (70) in the calculation was for a soil with HSG C. 3. The sheet flow length has been changed to 100 feet and the.rougluiess coefficient has been revised to 0.40 which reflects a "light woods" condition. The adjustment of these two numbers has increased the peak rate of runoff for the 2, 10 and 100 year storm events. These peak flows were recalculated using the computer program "Plydraflow Hydrographs for Windows" by Intelisolve. Hydrographs for the peak flows for the 2, 10 and 100 year storm event were plotted and are located in the Appendix to the report. 4. The design of the drainage swales utilizes the peak flow rate generated for the 100 year storm event by the SCS method. Peak flow hydrographs of the tributary areas to the two drainage swale areas are located in the Appendix of -he report. • SURVEYORS MHF Des�go CO"Isuftan1s, nc Mr, John Chessia, RE D cember t2, 1996 Page 2 of 3 The storm sewer design tables have been revised and we have included both the proposed Storm drainage system as well as the existing system i�. the ¢aj.)je�j, pj�, design tables are located iri Section L.) of dyeApperidix A 10 year design storm was., utilized arid the computer prognam "Stonnead" was used for the analysis.
