The Applicant hopes to expand opportunities for local businesses and service providers to maintain a presence in North Andover by providing small office space with potential garage bay for storage for use by various businesses such as engineers, surveyors, appraisers, etc. Existing infrastructure is installed to the site for water, sewer,drainage, electric, and telecommunications, The Project will provide office space for businesses with an expected occupancy of 12-15 employees that will contribute to local spending on goods, as well as provide opportunities for increased real estate tax and excise tax from real properties associated with the businesses. The Project as a whole is anticipated to increase revenue to the Town rather than be a burden on public services. The Project is buffered from adjacent residential properties on Bucklin Road by approximately 450 feet of wooded property. Adjacent properties to the south and east are commercial in nature.

Grasso,hereinafter the"Applicant,""Owner," and/or the"Proponent," seeks to construct a commercial building for use as a business office, associated parking, landscaping, utilities and stormwater management appurtenances (the Project or the Work). The work is proposed within the buffer zone to a bordering vegetated wetland (BVW), within the isolated vegetated wetland (IVW) of local jurisdiction, and adjacent to bordering land subject to flooding (BLSF). The Project will require relief to the local No Disturbance Zone (NDZ) and No Build Zone (NBZ). This Notice of Intent is filed for the proposed work within jurisdictional resource areas and/or their buffer zones protected under the 11fassachuselts Wellandls Protection Acl (MGL c. 131, Sec. 40; the Acl) and its implementing Regulations (310 CMR 10.00, et seq.; the Regulcrlions) and lands protected by the Town of North Andover Wetlands By-Law and its regulations. The work involves both temporary and permanent disturbances to these protected areas or their buffer zones, The following narrative provides a description of the site,associated resource areas, proposed activities and mitigation measures. Specific Project details are depicted on the accompanying Site Plan--189 Willott>Street in North Andover, Allcissaehusetls (6 sheets) prepared by Hayes Engineering, Inc. and dated November 21, 2022. Site Descri tian i The Project Site, located at 189 Willow Street is located within an existing commercial area to the west of Turnpike Street(Route 114) and along the easterly sideline of Willow Street. The site was previously permitted with an Order of Conditions issuing on May 4, 2005, for the construction of a commercial building and parking tinder DEP File No. 242-1279. The work proceeded with tree clearing, stripping of soil and installation of a box culvert to across the BVW resource area adjacent Willow Street. Tile building and parking were never constructed. A Certificate of Compliance was issues on September 14, 2009,for the work performed. The site is now revegetated with white pine saplings and opportunistic, hydrophytic vegetation in the areas of previous disturbance. The general location of the project is depicted oil Figure I -- USGS Location Map. The Project site includes the following jurisdictional resource areas and buffer zones: Jurisdictional Resource Arecrs Bordering Vegetated Wetlands Bordering Vegetated Wetlands (BVW) are freshwater wetlands which border on creeks, rivers, streams,ponds and lakes. The types of freshwater wetlands are wet meadows, marshes, swamps and bogs. BVW are areas where the soils are saturated and/or Notice of Intent 189 Willow Street North Andover,MA Page 23 inundated such that they support a predominance of wettand indicator plants. The ground and surface water regime and the vegetational community which occur in each type of freshwater wetland are specified in M.G.L. c. 131, § 40. The BVW associated with the Site surrounds the upland areas to the North, West, South and East, A previously installed box culvert spanning the southerly portion of the BVW was previously installed. BVW is represented by the "A"Flag Series on the accompanying plans. BVW is jurisdictional under the WPA and the Town of North Andover Wetland Bylaw. Isolated Vegetated Wetlands Isolated Vegetated Wetlands protected under the North Andover Wetlands Bylaw are freshwater wetlands, of at least 1,000 sq. ft. in surface area, that do not border on creeks, rivers, streams,ponds, or takes. The types of Isolated Vegetated Wetlands may include wet meadows, Inarshes, swamps, and bogs. The IVW associated with the Site is located within the center upland areas. The area has expanded since the 2005 Order of Conditions (OOC) as the topsoil was stripped and grading had commenced under the permit. The work remained unfinished and opportunistic, hydrophytic vegetation has taken root within the area indicated on the plans. The extent of the IVW is identified by the `B"Flag Series. Bordering Land Subject to Flooding Bordering Land Subject to Flooding is an area with low, flat topography adjacent to and inundated by flood waters rising from creeks, rivers, streams,ponds or lakes. It extends front the banks of these waterways and water bodies; where a bordering vegetated wetland occurs, it extends from said wetland. The extent of the resource area was determined through inforrnation provided by the National Flood Insurance Program (NFIP) Flood Insurance Rate Map (FIRM), Map 25009 CO236F (see Figure 2 -FIRM), revised through July 3, 2012. The NFIP issued two (2) letters of map amendment (LOMA) for properties immediately upstream and downstream of the Project. Because the flood elevation was not established the higher of the LOMA elevations (NAVD Elevation 236.5)was used as the extent of this resource area. Natural Heritage and Endangered Species Program The site does not contain any Priority or Estimated Habitat Areas, nor does it contain any Certified or Potential Vernal Pools as depicted on Figure 3 —NHESP Map. Ru fer Zones A 100-foot buffer to the BVW and IVW is depicted on the accompanying plans. The proposed Work is wholly within the 100-foot buffer zones under state and/or local jurisdiction. Notice of Intent 189 Willow Street North Andover,MA Page 24 1, 1 The local 25-foot No Disturbance Zone(NDZ) is depicted on the accompanying plans, an alternatives analysis and waiver request accompany this application. The local 50-foot No Build Zone is depicted on the accompanying, an alternatives analysis and waiver request accompany this application. i Work Description The Project consists of the construction of a 7,776-sf. business office building, associated i parking, utilities, and stormwater management appurtenances. The Project is located wholly within the 1.00-foot buffer zone with portions located within tre 25-foot no disturbance zone and 50-foot no build zone, Honoring these zones would render any project on the site unfeasible and result in the Proponents inability to use the Property. As indicated previously a waiver request and alternatives analysis for this work is included as Appendix E. These proposed activities are further detailed oil the accompanying Ph-in to Acconipany Notice of Intent in North Andover, Alfcissochuyetts (attached). Although construction timing and construction"means and method"sequencing is subject to change, it is anticipated that the following general sequence will be followed: 1. Prior to construction the Applicant will install erosion and sedimentation controls on the site. 2. Upon installation of erosion controls and inspection, a pre construction conference with project stakeholders will be held to further discuss project timing and reporting. 3. While tie work is ongoing the contractor will follow the continued monitoring and repair of erosion and sedimentation controls as detailed in the accompanying Construction Period Pollution Prevention Plan. 4. Tree clearing and removal of topsoil will commence. 5. Foundation installation and preparation of the proposed driveway will commence. 6. Construction of the site drive,parking,utilities, and drainage. 7. Installation of landscaping. 8. As-built survey documenting compliance and request for Certificate of Compliance. T,Vork in Resource Areas The Project proposes minor disturbances to the state and local jurisdictional bordering land subject to flooding. The proposed work will result in 217 square feet(73.3 cubic i Notice of Intent ]89 wi I low Street North Andover,MA Page 25 i E feet) of disturbance to the BLSF resource area. The Proponent will create 936 square feet (312 cubic feet) of compensatory storage as a result of the proposed disturbance. The Project will result in the loss of 4,705 square feet of impacts to the local jurisdictional 1VW and result in 1,197 square feet of replicated IVW and a total of 1,623 square feet of IV W remaining at the Site. Mork in Buffet-Zone s Work within the area 100-feet landward from the top of Coastal Bank consists of approximately 52-square feet of the southeastern corner of the proposed accessory structure. It is anticipated that temporary disturbances of the adjacent work area within the limits of the erosion controls depicted on the accompanying plans will also occur. No work is proposed within 50-feet of the Coastal Batik or within the local Mitigation and No Disturbance Zones. The closest point for any erosion control or construction access is 58-feet from the Coastal Bank. Because the Coastal Bank is coincident with an existing retaining wall with a gentle slope above, and the work is located greater than 50-feet from same, the work will not result in an adverse effect to the Coastal Bank due to wave action on the movement of sediment from the coastal bank to coastal beaches or land subject to tidal action. Mitigation Measures Construction activities, including foundation excavation and grading will create erodible surfaces and should be limited to those areas necessary to safely operate equipment and conduct the proposed work. A construction period pollution prevention plan accompanies this report detailing construction best practices. Erosion and Sedinnenotion Controls An erosion and sedimentation control program will be implemented to protect resource areas from sedimentation due to the proposed construction activities. Work and stockpile areas are to be protected by an erosion control barrier prior to construction and erosion controls shall remain in place until all disturbed areas are stabilized. Erosion and sedimentation controls proposed are indicated on the accompanying Plan to Accompany,Notice of Intent on Sheet 3 of G. Erosion and sedimentation controls proposed for the Project include the following: Erosion Control Barriers Prior to any construction activities on the site, a barrier of staked straw wattles will be installed in accordance with the accompanying plans. As construction progresses, additional rows of wattles will be installed around the base of stockpiles and other erosion prone areas. Notice of Intent 189 Willow Street North Andover,MA Page 26 i Wattle installation should be inspected weekly, at a mininium, during construction activities and after significant rainfall events. If sediment has accumulated to a depth impairing the prober function of the wattle barrier, it will be removed and reused on-site or disposed of at a suitable offsite location. Any damaged section of wattle shall be repaired or replaced immediately upon discovery. Catch Basin Inlet Protection All existing and proposed catch basins on-site and within 200-feet of the work area, shall be fitted with Siltsacic tz, or equivalent, catch basin filters. Catch basin filters should be inspected weekly, at a minimum, during construction activities and after significant rainfall events. If sediment has accumulated to a depth impairing the proper function of the filter, the sediment Mill be removed and reused on-site or disposed of at a suitable offsite location. Any damaged catch basin filters shall be repaired or replaced immediately upon discovery. Stabilized Construction Entrance A stabilized construction entrance/tracking pad should be provided in locations where construction vehicles will transition from pervious (grass, dirt, etc) surfaces onto paved surfaces to mitigate the tracking of sediment onto adjacent public rights of way. The construction entrance shall consist of 1-'/2-inch crushed stone placed 12-inches deep. The construction entrance should be a minimum of 10-feet in width and 50-feet in length. The entrance should he maintained in a condition that will prevent tracking or flowing of sediment onto public rights-of-way. This may require the periodic topdressing with additional stone. The entrance should be inspected weekly and after significant rainfall events, Any thud or sediment tracked onto adjacent roadways should be removed immediate]),. Non-structural Practices Non-structural best management practices to be used during construction include pavement sweeping, dust control, temporary stabilization, and temporary seeding. These practices should be applied as applicable during construction activities. Pavement Sweepm On-site driveways, parking areas an([ adjacent roadways should be swept as necessary during construction activities. Sweeping may be done by hand or mechanically. Notice of Intent 189 willow Street North Andover,MA Page 27 Dust Control Dust control should be Provided by soil wetting only,the use of calcium chloride or other chemical means of dust Prevention shall not be used on the Project. When necessary, exposed surfaces should be wetted to Prevent wind-borne transport of sediment(dust). Water should be applied in a volume equivalent to %2-inch over the exposed areas. The water should be applied in a manner that minimizes erosion, such as a mechanical sprayer mounted to a water truck. Tempor�arytabilization Any areas of exposed soil or soil stockpiles that will remain inactive for more than 14- days shall be covered with a layer of straw mulch applied at a rate of 90 pounds per 1,000 sf. The mulch should be anchored with a tacking coat, applied by hydra seeder. Steep slopes (greater than 15%) should be covered with fiber mats and anchored with photodegradable staples at a density in accordance with the manufacturer's specifications. Temporary Seeding If conditions allow, temporary vegetative cover should be established on areas of exposed soil (including soil stockpiles)that remain inactive for more than 60-days. Tire seed mixture should be applied by a hydro-seeder with a tacking coat and should include a mixture of rapid germinating grasses that are indigenous to New England. Stornntpater Controls The Project is subject to the requirements of the Massachusetts Stormwater Handbook and the Town of North Andover Stormwater Standards. Please refer to Appendix D— Stormwater Management Report for detailed hydrologic calculations and analysis. Regulatory Com.pliance The Regulations under the Act identify several Performance Standards for proposed work activities within jurisdictional resource areas and buffer zones. Borclerin Ye etcrted Wetleinds BVW No work is proposed within this resource area. The Project is wholly located within the 100-foot buffer zone to a BVW. The Project, as designed, minin-rizes impacts to the BVW to tine maximum extent practicable and provides requisite stornrwater management and erosion controls such that the Project will have no adverse effect to this resource area. Notice of Intent 189 willow Street North Andover,MA Page 28 i Isolated Vegetaled Wellands (IEff'Z i IVW is a resource area under local jurisdiction only. The 1VW areas at the site have j expanded due to incomplete site grading associated with the previous OOC issued for the Site. The Applicant proposes to construct over portions of this IVW area and provide replication to the maximum extent practicable. The Project would not be able to be constructed without this disturbance. Bordering Land Sul ecl to Floocin BLSF BLSF is both a resource area under both state and local jurisdiction. Minimal intrusion into this resource area is proposed.

Grasso, hereinafter the"Applicant...cc Owner," and/or the "Proponent,"seeks to construct a commercial building for use as a business office, associated parking, landscaping, utilities and stormwater management appurtenances (the Project or the Work). The work is proposed within the buffer zone to a bordering vegetated wetland (BVW), within the isolated vegetated wetland (IVW) of local jurisdiction, and adjacent to bordering land subject to flooding (BLSF). The Project will require relief to the local No Disturbance Zone (NDZ)and No Build Zone (NBZ). 1.1 Pre-Development Conditions The Project Site, located at 189 Willow Street is located within an existing commercial area to the west of Turnpike Street(Route 114)and along the easterly sideline of Willow Street. The site was previously permitted with an Order of Conditions issuing on May 4, 2005, for the construction of a commercial building and parking under DEP File No, 242- 1279. The work proceeded with tree clearing, stripping of soil and installation of a box culvert to across the BVW resource area adjacent Willow Street. The building and parking were never constructed. A Certificate of Compliance was issues on September 14,2009, for the work performed, Tile site is now revegetated with white pine saplings and opportunistic, hydrophytic vegetation in the areas of previous disturbance. The United States Department of Agriculture Natural Resource Conservation Service (MRCS) Soil Survey mapping indicates that soils on site are representative of Hydrologic Soil Group (I-ISG) D. NRCS Soil Survey Mapping and Soil Data accompany this report as Appendix A. 1.2 Post--Development Conditions The Project consists of the construction of a 7,776-sf. business office building, associated parking, utilities, and stormwater management appurtenances. Proposed stormwater management for the Project consists of the Construction of a sediment forebay, treatment swale and extended detention basin to provide TSS removal and mitigation of peals flows. Because of the highwater table and presence of poorly drained HSG D soils no recharge is proposed with the project. 2.0 Stormwater Management 2.1 Pre-Development Conditions 2.1.1 Drainage 5yslein The Project Site in the pre-development conditions drains to the bordering vegetated wetlands that surrounds the site. Portions of the site to the west are Siornmater Management Report 189 Willow street North Andover,MA Page 5 associated with the Bordering Land Subject to Flooding(BLS>?) for Mosquito Brook. 2.1.2 Watersheds Under existing conditions, the site wholly drains to the adjacent BVW. The Site has been modelled using a single sub-eatchment tributary to the design point of comparison at the edge of the BVW associated with wetland flag series A. 2.1.3 Ramoff Calculations Runoff calculations were performed in accordance with the methodology outlined in the NRCS Soil Conservation Service (SCS)methods as defined in Technical Release 55 (TR-55) and Technical Release 20 (TR-20)which are the basis for they HydroCADO hydrologic model. Existing cover conditions and times of concentrations were used to generate runoff hydrographs for the sub-catchment in each of the Type III design storms in accordance with NOAA Atlas 14, as identified in Table 1.

Newly created impervious surfaces are routed through a treatment system consisting of a sediment forebay, water treatment swale, and extended detention basin prior to discharge at a terminal level spreader, 2.1.2 T47atenyheds Under the proposed conditions, the site wholly drains to the adjacent BVW. The Site has been modelled using three sub-catchment tributary to the design point of comparison at the edge of the BVW associated with wetland flag series-A. Theses sub-catchment areas are: P.I the areas tributary to the proposed IVW replication area; P.2 the developed portion of the site tributary to the proposed stormwater management system; and P.3 the pervious areas directly tributary to the BVW. 2.1.3 Runoff Calculalions Similar to the pre-development conditions runoff calculations were performed in accordance with the methodology outlined in the NRCS Soil Conservation Service (SCS) methods as defined in Technical Release 55 (TR-55) and Technical Release 20 (TR-20) which are the basis for they I IydroCADOO hydrologic model. Existing cover conditions and times of concentrations were used to generate runoff hydrographs for the sub-catchment in each of the Type III design storms in accordance with NOAA Atlas 14, as identified previoulsy in Table 1. Post-development pear rates of runoff to the Study Point of Comparison are summarized in Table 3, below.

Each of the standards and the extent of Project compliance are summarized below, Please refer to Appendix D for the completed MassDEP Storm Water Checklist. 3.1 Standard 1 —No New Untreated,Discharges No ne1N storm water conveyances (e.g our falls) may discharge untreated storm>rater directly to or cause erosion in jvetknrds or tvatens of the Conrrnonfveafth. The Project does not discharge any storm water from newly created impervious surfaces directly to a wetland or water of the Commonwealth. Storm water quality controls are proposed including a sediment forebay,water quality treatment swale, and extended detention basin. Treated stormwater enters the BVW via the culvert discharge from RESO1, the extended detention basin. The 2-year, 24-hour storm velocity identified in the HydroCAD model is 2.57 feet per second (fps)prior to entering the proposed level spreader. Table 2.3.1 of Volume 3, Chapter l of the Massachusetts Department of Environmental Protection's (MaDEPS) stormwater Handbook(provided below)provides permissible velocities for channels using the maximum velocity for the 2-year, 24-hour storm, The maximum velocity in the 2-year, 24-hour storin (2,57 fps) is below the permissible velocity for a grass having a channel slope between 0 and 5-percent.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups(A, B, C, and D) and three dual classes (AID, BID, and CID). The groups are defined as follows: Group A. Soils having a high infiltration rate(low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate(high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, BID, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Areas that are barren and/or showing signs of erosion should be stabilized through immediate re-vegetation. Debris and Litter Removal E Litter and other debris may collect in storm water best management practices (BMPs), potentially causing clogging of facilities, All debris and litter shall be removed as necessary, at a minimum of four(4) times per year in the spring, summer, fall and winter. Debris and litter should be removed from the wetland resource areas (bordering and isolated vegetated wetlands)on a weekly basis. The dumpster area, and dumpsters, should remain closed and contained at all tunes. Bio-Filter Swale Mulch the swale annually in the spring. Dead vegetation should be removed twice annually in the early spring and late fall. Sparsely vegetated areas should be raked and re-seeded at this time. Clean swale of litter, debris, and sediment at a minimum four(4)times per year. Sediment Forebay Jn accordance 10th Volume 2, Chapter 2 of the AllassDEP Storm Water Hcmclbook as summarized below: Sediments and associated pollutants are removed only when sediment forebays are actually cleaned out, so regular maintenance is essential. Frequently removing accumulated sediments will make it less likely that sediments will be resuspended. At a minimum, inspect sediment forebays monthly and clean them out at least four times per year. Stabilize the floor and sidewalls of the sediment forebay before making it operational, otherwise the practice will discharge excess amounts of suspended sediments. When mowing grasses, keep the grass height no greater than 6 inches. Set mower blades no lower than 3 to 4 inches. Check for signs of Tilling and gullying and repair as needed. After removing the sediment, replace any vegetation damaged during the clean-out by either reseeding or resodding. When reseeding, incorporate practices such as hydroseeding with a tackifier, blanket, or similar practice to ensure that no scour occurs in the forebay, while the seeds germinate and develop roots. Extended Detention Basin Ii1 Accordance ivith Volmne 2, Clicipter 2 of the MassDEP Storin Writer Handbook Cold -llanufaclurer's reconnnendations cis sununcirized belori,: Inspect the basin at least twice per year including the outlet structure. Remove any debris that inight clog the system. Inspect level of sediment and remove at least once every 5-years. Mow the side slopes, upper stage and embankment at least twice per year. Good Housekeeping Practices: Provisions for storing paints, cleaners, automotive waste and other potentially hazardous household waste products inside or under cover: • All materials stored on-site shall be in a neat, orderly manner in their appropriate containers with original manufacturer's label(s); • Only store enough material as needed; whenever possible, all of a product shall be used prior to disposing of container; • Manufacturer,federal, state and local recommendations for proper use and disposal shall be followed. f Vehicle Washing Controls: • Use commercial car washes whenever possible. Car washes treat and/or recycle wash water; • There shall be no on-site washing of vehicles. Routine Inspection and Maintenance of Storn3 Water BMPs • Previously addressed. Spill Prevention and Response Plans • Spill control practices shall be in conformance with the guidelines set forth in the National Pollutant Discharge Elimination System (NPDES) Storm Water Pollution Prevention Plan (SWPPP). Maintenance of Lawns, Gardens and Other Landscaped Areas: • Grass shall not be cut shorter than two (2)to three (3) inches and mulch clipping should be left on lawns as a natural fertilizer; 1 i • Use low volume water approaches for irrigation such as drip-type or sprinkler systems, Water plants only when needed to enhance root growth and avoid runoff problems; • Mulch shall be used wherever practicable, Mulch helps retain water and prevents erosion. Storage and Use of Fertilizers,Herbicides and Pesticides: • fertilizers shall be applied in the minimum amounts recommended by the manufacturer. Once applied, fertilizer shall be worked into the soil to limit exposure to storm water. Storage will be in covered areas only. Contents of partially used bags sliall be transferred into scalable plastic containers to avoid spills; • Do not fertilize before or during rain events; • Consider the use of organic fertilizers; • Pesticides shall be applied only when necessary and only in the minimum amounts recommended by the manufacturer.
