The Earle Street public right of way is owned by the City of Northampton and is approximately 2,100± linear feet between Prince Street (Route 66) and South Street (Route 10). The Mill River lies east of Earle Street in an area with both industrial and residential properties. The Mill River passes under South Street east of the .Earle Street /South Street intersection. Land owned by the Massachusetts Electric Company, formerly owned by the New York, New Haven, & Hartford Railroad, abuts Earle Street at the intersection of Grove Street and Texas Road. Earle Street is also adjacent to land owned by Hospital Hill Development, LCC, the City of Northampton, and other private landowners. Currently, Earle Street accommodates vehicular traffic, cyclists, and pedestrians within a common 2 -lane bituminous concrete surface that varies in width between 22 and 26 feet. Improvements to Earle Street include widening the shoulders of the right of way to provide bicycle lanes, installing a 6 -foot wide pedestrian sidewalk on one side of the road, and improving the stormwater management system. These improvements will coincide with the upgrading of the Earle Street and Grove Street intersection that is being completed as a separate project. The reconstruction of Earle Street is designed to improve the safety of the traveled right of way for motorists, cyclists, and pedestrians. Additionally, stormwater improvements are proposed to provide improved treatment of stormwater where current stormwater drains are substandard or nonexistent. Grading to support the proposed project will also occur. SEALS AND THOMAS, INC. Project Narrative 1 2.0 EXISTING CONDITIONS Notice of Intent Earle Street Reconstruction Northampton, Massachusetts 170001N1001.doc Site Description The paved portion of the Earle Street right of way includes a 22 to 26 -foot variable width bituminous concrete surface with portions of bituminous concrete curbing within the intersections. Existing impervious area within the work site totals 100,000± square feet and areas on the shoulder of the paved surface are grass or gravel. The majority of the unpaved portion of the Earle Street right of way consists of grass or gravel with small wooded areas located proximate to the intersection of Grove Street and northwest of Earle Street on a portion of the land owned by Hospital Hill Development, LLC. Earle Street is generally flat with elevation changes along the centerline between 134 and 148 feet. High elevations occur along the central portion of the right of way, north of Grove Street, while the lowest elevations are proximate to the intersection of Earle Street and South Street, adjacent to the Mill River. The shoulders adjacent to the Massachusetts Electric Company and the Northampton Gas Light Company properties contain near 2:1 grass slopes. The majority of the Earle Street right of way lies within the 100 -foot buffer zone to BVW. The southern portion of Earle Street between Grove Street and South Street also lies within the 200 - foot Riverfront Area (RFA) to the Mill River. BVWs are located east and west of Earle Street within the southern portion of the work area and east of the portion of Earle Street north of the intersection with Grove Street. The wetlands west of Earle Street located on land owned by the Commonwealth of Massachusetts and the wetlands located north of the Grove Street intersection and east of Earle Street are separated from Earle Street by the former New York, New Haven, and Hartford Railroad (discussed further in the "Wetland Resource Areas" section below). Water, electric, sewer, gas, and communication utilities currently service properties on the northern portion of Earle Street and all of South Street. Several catch basins located at the intersections of South Street and Carl S. Carrado Way convey stormwater to a Bordering Vegetated Wetland (BVW) located east of Earle Street. Catch basins are also located within the intersection of Grove Street and Texas Road, as well as in the northern portion of Earle Street. The City storm drains discharge to a system of drainage swales and wetlands eventually leading to the Mill River. Portions of Earle Street, between Carl S. Carrado Way and Grove Street, which are within Riverfront Area, have no curbing. Water, sediments, and pollutants from the paved surface of Earle Street potentially flow directly to the Mill River with no prior treatment. According to the USDA Soil Conservation Service Soil Survey of Hampshire County Massachusetts, Amostown - Windsor silty substratum -Urban land complex (Au), Belgrade silt loam, 3 to 8 percent slopes (BaB), and Boxford silt loam, 8 to 15 percent slopes (BoC) exist within the Earle Street right of way. The soils consist of deep, nearly level and gently sloping, moderately well drained soils and broad, level areas covered by buildings, sidewalks, parking lots, roads, and railroads. BEALS. AND THOMAS, INC. Project Narrative 2 Wetland Resource Areas The site contains Bordering 'Vegetated Wetland (BVW), Bordering Land Subject to Flooding (BLSF), and Riverfront Area (RFA). BVW is located east and west of Earle Street within the southern portion and east of Earle Street north of the Grove Street intersection. There is a 100 -foot buffer zone associated with BVW. The Mill River is identified on the most recent USGS map as a perennial river and has an r-, associated 200 -foot RFA. Portions of this RFA are currently degraded by existing paved and gravel surfaces. Specifically 17,355 square feet of RFA is degraded within the worksite. The Bank of the Mill River is composed of riprap with some vegetation on the upper portions of Bank. i L J SC D ig iti z ed Check Notice of Intent Earle Street Reconstruction Northam pton, -Massachusetts 170001 N1001.doc Based upon the Natural Heritage and Endangered Species Program (NHESP), 2005 digital data layer from MassGIS the southern portion of Earle Street, proximate to the intersection with South Street, is located within an Estimated Habitat of Rare Wildlife, area WH 228, as well as a Priority Habitat of Rare Species, area PH 44. BEALS AND. THOMAS, INC. Project Narrative 3 Impacts to Resource Areas Portions of work are proposed within RFA, BVW, and the 100 -foot buffer zone thereto, which are associated with the Mill River and wetlands proximate to Earle Street Although the amount of work within RFA totals 52,008 square feet, only 12,754 square feet constitutes new pavement within previously non - degraded RFA. This project is a Limited Project per 310 CMR 10.53(3) and all means to avoid and minimize impact have been taken to impose such conditions as will contribute to the interests identified in M.G.L. c. 131 § 40. 1 LJ 3.0 PROPOSED CONDITIONS Notice of Intent Earle Street Reconstruction Northampton Massachusetts - -- 170001 N1001.doc The proposed project will widen the existing paved traveled way to include bike lanes along the shoulders and the installation of a sidewalk along one side of the road. The sidewalk will be on the western side of Earle Street north of the Grove Street intersection and on the eastern side of Earle Street, south of the Grove Street intersection. Additionally, curbing will be installed and stormwater management structures will be added /upgraded to accommodate the wider roadway. Associated grading and landscaping will be undertaken to stabilize and vegetate disturbed areas during and after construction. Riprap will be installed adjacent to the sidewalk on the eastern side of Earle Street, north of the intersection with South Street, to stabilize the slope, slow the flow of surficial runoff and improve ground water recharge. The curbing and stormwater management system is provided to mitigate the impacts of the increased runoff created by the added impervious surfaces on the site. The drainage system will be integrated with the current storm water drainage infrastructure and upon completion will include deep -sump catch basins with hoods as well as bicycle -safe grates. The design mitigates the net peak rates of runoff for the 2 and 10 -year storm events. Proposed outflows from the catch basins in the southern portion of the work area are directed to the existing outflow points within the adjacent wetland area and above the top of Bank to the Mill River to mimic existing conditions. No adverse flooding or increased erosion associated with the roadway and site runoff is anticipated. For additional information on the stormwater management system see Section 4. At minimum, a 20 -foot wide undisturbed buffer between the work area and the river has been maintained, stormwater management has been unproved, and work will not impair the RFA's 'ability to provide wildlife habitat or protect groundwater /surface water quality. Earle Street is located adjacent to an abandoned railway line and industrial properties, and the majority of work is limited to previously developed /disturbed areas, therefore negative impacts to wildlife are not anticipated. The installation of the stormwater system will improve the quality of runoff prior to discharge. Although work is proposed within BVW, only 315 square feet of the southeastern most BVW will be impacted by fill. Impact to BVW was minimized by locating the improvements at the intersection of Earle and South Streets as distant from the wetland as was possible and still BEALS AND THOMAS, _INC. Project Narrative 4 Notice of Intent Earle Street Reconstruction Northampton, Massachusetts 170001NI001.doc maintain the safety standards required for the intersection and roadway improvements. Increasing the steepness of the slopes alongside Earle Street will minimize impact to BVW and the proposed riprap- stabilized slopes will be further away from BVW than traditional graded and seeded slopes. Portions of Bordering Land Subject to Flooding (BLSF) are located between an elevation of 126 and 127 feet proximate to the intersection of Earle and South Streets. Although work is proposed adjacent to BLSF, no fill is proposed below an elevation of 127 feet. Therefore, there will be no loss of flood storage capacity. The relatively steep off - grading of slopes alongside Earle Street will minimize impact to lands adjacent to BLSF and the proposed 1:1 riprap- stabilized slopes will be further away from BLSF than traditional 2:1 graded and seeded slopes. Alternatives Analysis Per 310 CMR 10.58(4), where a project involves work within RFA, an analysis discussing various alternatives must be provided. The scope of this analysis (provided below) only addresses work within RFA (i.e. the southernmost portion of Earle Street). Additionally, the area within RFA is also proximate to those areas identified as rare species habitat on the Natural Heritage and Endangered Species 2005 digital data layer from MassGIS. Per 310 CMR 10.53(3) alternatives to the proposed activity impacting specified habitat types of rare vertebrate and invertebrate species are also discussed below. Alternative No. 1 Alternative 1 is the "no action" alternative. The no action alternative would have no implementation costs, nor would there be any alteration to RFA. This alternative provides no safety improvements along the roadway for motorists, cyclists, and pedestrians, nor the unproved intersections of Earle and Grove Street or Earle and South Streets. Additionally, leaving existing paved portions of road as they are permits stormwater runoff to reach. the Mill River without passing through drainage structures. Finally, there would be no safe road crossings for a future rail to trail improvement connecting with the Historic Mill River Revitalization Project. This alternative would have no impact on current specified habitat types. Alternative No. 2 Alternative 2 would entail removing Earle Street from RFA and /or reducing its size. This could be accomplished by moving Earle Street west from its existing location. Although such relocation would remove the pavement from RFA, this would result in direct alteration of BVW and a potential loss of 14,000± square feet of wetlands. Furthermore, the alternative would create significantly more impervious surface within unpaved uplands and wetlands. Reducing the roadway width would create a paved surface that is inadequate to public safety objectives. This alternative would nearly remove any proposed alterations from specified priority habitat areas; however, construction of new impervious surface within a previously undisturbed BVW and adjacent uplands could potentially compound adverse affects on rare species inhabiting that wetland, as well as those within the Riverfront Area. BEALS AND THOMAS, .INC. Project Narrative 5 Notice of Intent Earle Street Reconstruction Northampton, Massachusetts 170001 N1001.doc Preferred Alternative Based upon review of the previous two alternatives, a third preferred alternative will be employed. This alternative consists of reconstructing Earle Street as illustrated on the attached plans. Although located within RFA, it is not anticipated that the additional paved area will negatively impact the Mill River or its associated RFA, as the majority of the new pavement is generally located within the route of the present traveled way. The 20 -foot buffer that separates the work area from the Mill River will include a vegetated buffer, riprap Bank, and wetlands adjacent to the Bank. Although the proposed Earle Street reconstruction is within areas identified as estimated habitat for rare or endangered species, the preferred alternative is not anticipated to significantly impact any natural areas as the work area is proximate to degraded Riverfront Area and therefore is not anticipated to have any adverse affects on rare species. Mitigation for Impacts to Resource Areas Paving of existing impervious or otherwise disturbed areas and installation of the associated stormwater management system will provide appropriate treatment for stormwater runoff that currently infiltrates untreated into the ground and the Mill River. Proposed impervious surfaces are located away from the Mill River to the greatest extent practicable. Existing conditions within RFA will be improved, as the installation of curbing and incorporation of the stormwater management system will promote passive treatment of stormwater runoff. Where impervious surfaces are within the buffer zone to the BVW located west of Earle Street, the limit of work is separated from the wetland by the upgradient, abandoned railway right of way. Where paving or sidewalks are proposed north of the intersection with Grove Street, expansion is proposed on the most distal side of Earle Street to preserve the existing buffer between Earle Street and the BVW. The overall magnitude of improvements to Earle Street will be minimized to those components necessary to improve the safety of multi -modal traffic and improve the intersections with South Street and Grove Street.

Protection. of Public and Private Water Supply and Ground Water Supply The site is not located within a Zone II water supply protection area. According to data available through MassGIS the area does not overlay any medium or high yield aquifers. Also, adding curbing and the improvement of the stormwater system will improve the quality of runoff prior to discharge. Therefore the Protection of Public and Private Water Supply and Groundwater Supply interests of the Act and Ordinance have been addressed. Flood Control and Storm Damage Prevention According to FIRM Community Panel # 250167 0002 A, a portion of the work site is located adjacent to the 100 -year floodplain (Bordering Land Subject to Flooding). The curbing and stormwater management system is provided to mitigate the impacts of the increased runoff created by the impervious surfaces on the site. The design mitigates the net peak rates of runoff for the 2 and 10 -year storm events by incorporating a detention basin. The outflow from the drainage system is directed to the existing points of outflow within the adjacent wetland area and above the top of Bank to the Mill River to mimic the runoff under existing conditions. No adverse flooding or erosion impacts associated with the roadway and the site runoff are anticipated. Therefore the flood control and storm damage prevention interests of the Act and Ordinance will be improved. Prevention of Pollution Erosion control barriers will be placed on the eastern edge of the limit of work in order to define the work area and preclude any sediment transport from entering BVW and the Mill River. Once work has been completed, disturbed areas will be re- vegetated and stabilized to prevent erosion. As previously discussed, various measures have been incorporated into the design to further prevent pollution. Such design elements include curbing and deep -sump catch basins with hoods to manage stormwater runoff. Therefore, the pollution interests of the Act and Ordinance will be upheld. Protection of Fisheries, Shellfisheries and Wildlife Habitat According to the Massachusetts Natural Heritage Atlas, 2005 MassGIS digital data layer, the site contains Natural Heritage Endangered Species Program designated areas of priority habitat for rare species and estimated habitat of rare wildlife. It is not anticipated that the proposed project will negatively effect wildlife habitat, as work is relegated to mainly disturbed areas. It is likely that the Mill River contains fish and or shellfish, however the project will not affect water quality or the ecology of the River. Therefore, the fisheries, shellfisheries, and wildlife habitat interests of the Act and Ordinance will be protected. BEALS AND THOMAS, INC. Project Narrative 7 Notice of Intent Earle Street Reconstruction Northam pton, Massachusetts-- 170001 N1001.doc Recreation Earle Street currently does not provide significant recreation opportunities. The proposed project will increase the recreation opportunities within the area of work by adding a sidewalk, bicycle lane, and connection with a proposed rail -to -trail path. Therefore, the recreation interests of the Ordinance will be protected and enhanced. Agriculture Earle Street is a paved public right of way and currently does not provide agricultural uses. Therefore, the agriculture interests of the Ordinance will not be altered. Aesthetic Values Work is within an existing roadway system and is not anticipated to decrease the current aesthetic values of Earle Street. Therefore, the aesthetic values interests of the Ordinance will be protected. BEALS AND THOMAS, INC.

Douglas - _.. — Representative (If any) x /66_ Date S Digitized Checked r' i Stormwater Management Form Summary An upgraded Earle Street was selected as the preferred alternative for improving access from the proposed Hospital Hill Development (IIIID) site to Route 10 during the Environmental review process for the site. The primary reason was minimizing wetland impacts. The Earle Street reconstruction project proposes to widen existing lanes and shoulders, provide a sidewalk on one side of the road, correct a substandard intersection, and will involve repaving and alterations to drainage systems on the existing roadway, therefore this is a redevelopment project as defined in the DEP Stormwater Management Policy and guidelines. A number of constraints exist for providing stormwater controls within the project limits, including, but not limited to: • Limited land availability within the right -of -way and the developed nature of land within and adjacent to the right-of-way; • Use of the existing drainage system for both existing and new paved areas appropriate to the limited size and scope of this project; and • Disturbed and compacted nature of soils providing limited capacity for infiltration. Recognizing these constraints, the proposed project has complied with all of the applicable stormwater performance standards to the maximum extent practicable. The following summarizes the proposed project's compliance with the Performance Standards: Standard #1: Untreated Stormwater: The project does not propose new stormwater outfalls. This project will utilize the existing outfall locations. r ?� 6:13436 Norttamptor'ReportslStomtwater Compliance 0406.dc 7 Standard #2: Post- Development Peak Discharges Rates: Although the impervious area is increasing no net increase in peak rate under the 2- and 10 -year storm events is projected at the Mill River. This is a result of large portions of existing tributary areas contributing directly to the Earle Street system being diverted to a proposed detention basin as part of the proposed improvements on the HHD site. The detention basin reduces the peak flow contributing to the Earle Street drainage system and the overall peak flow contributing to the Mill River. It is also anticipated that the direct discharge of the Earle Street system to the Mill River will have ample time to discharge prior to the peak arriving in the Mill River from upgradient drainage areas. The 100 -year event has been evaluated, and since a reduction in flow is projected no increase in flooding down - gradient of the site is anticipated. No adverse flooding or erosion impacts associated with the roadway and the site runoff are anticipated. Standard #3: Recharge to Groundwater: Recharge has not been provided within the project area due to the limited infiltration capacity of site soils, the potential for adverse impact to roadway substructures, and the potential for increased risk of groundwater contamination. The HHD site, for which the improvements of the roadway is required, more than offsets the minor decrease in recharge associated with this proposed project. Standard #4: 80% TSS Removal: The modified stormwater treatment system will not achieve 80% TSS removal for roadway discharges within the project area. Much of the existing roadway is not curbed and therefore potentially polluted stormwater runoff discharges directly to the resource areas. The proposed project will install curb for the entire length of roadway and along with the proposed street sweeping and the installation of deep -sump catch basins with hoods will provide an improved level of treatment over existing conditions. In addition, the combined effect of the roadway improvement project, and redevelopment and regarding of the HHD site provides r'} a reduction in peak flow discharges as well as storfn water treatment, which also provides es an improvement over existing conditions. Given the space constraints within the right -of -way and limited scope and magnitude of this project, this standard has been met to the greatest extent practicable, and represents an improvement over existing conditions. Standard #5: Higher Potential Pollutant Loads: The proposed project does not contain and uses defined by DEP to have higher potential pollutant loads. Therefore, Standard #5 is not applicable to this project. • Standard #6: Protection of Critical Areas: The project site is located in or immediately adjacent to areas of protected habitats of rare species and estimated habitats of rare wildlife. Initial contact has been made with the Natural Heritage & Endangered Species Program (NHESP). The Notice of intent with the project plans will be submitted to the NI:IESP for review. Based on Division of Fisheries and Wildlife comments received for the Manhan Rail Trail Project — NBESP File No. 05- 17328, it is anticipated that this project will not result in an adverse impact to the actual Resource Area Habitat and will also provide for proper protection during construction. Copies of the Division of Fisheries and Wildlife letters are attached. Standard #7: Redevelopment Project: The Earle Street reconstruction project proposes to widen existing lanes and shoulders, provide a sidewalk on one side of the road, correct a substandard intersection, and involves repaving and alterations to drainage systems on an existing , roadway, therefore this is a redevelopment project as defined in the DEP Stormwater Management Policy and guidelines. Therefore, Standard #7 applies to this site. Standard #8: Erosion /Sediment Control: The project design will incorporate erosion and sediment controls to prevent erosion, control sediment movement, and stabilize exposed soils. Proposed sediment and erosion controls are described in the Notice of Intent, and are illustrated on the General Plans included with this submittal. Standard #9: Operation and Maintenance Plan: An operation and maintenance plan is described in the Notice of Intent, and will be implemented to ensure the long -term function of the stormwater management system for this site.

J ■ Section 5 Wetland Boundary Documentation Request for Determination of Applicability Application Narrative, July 3, 2002 Phase One Report, Wetlands Resources Section, April 30, 2002 Draft Environmental Impact Report Site Wetlands Delineation Approval Section, April 2003 2.0 Project Locus ATTACHMENT A PROJECT NARRATIVE 1.0 Introduction In accordance with the MA Wetland Protection Act (MGL c.131 s.40) and Regulations (310 CMR 10.00) (the "Act ") and the City of Northampton Wetlands Protection Ordinance (the "Ordinance "), MassDevelopment (the "Applicant ") is formally requesting that the Northampton Conservation Commission (NCC) confirm the . following state and local wetland resource area boundaries: • Bordering Vegetated Wetlands (wetland series #1, #2 and #3); • Inland Bank; • Bordering Land Subject to Flooding (Mill River — elevation 126'/127' NGVD); and • 200 -foot Riverfront Area (Mill River). A vegetated slope situated on the uphill side of Earle Street was saturated at the time of inspection but was not considered to be a jurisdictional wetland resource area. Two culverts convey pavement and /or rooftop runoff from the upper parking lot onto this sloped area towards Earle Street. As a result, this area was considered a component of the existing stormwater management system, functioning as a "level spreader" where stormwaterr flows are uniformly spread out over the ground as sheet flow (thus preventing concentrated, erosive flows), rather than a viable wetland. While Phase 1 build -out activities associated with the Village at Hospital Hill redevelopment project (the former Northampton State Hospital site) are not proposed as part of this application, the 100 -foot Buffer Zone to Bordering Vegetated Wetlands and the 40 -foot Buffer Zone to Bordering Land Subject to Flooding (see . Section 24:9 of the Ordinance), have been depicted on the attached existing conditions site plans. As applicable, one or more Notices of Intent describing such work will be filed with the Northampton Conservation Commission in the future as Phase 1 project design advances. This RDA application incorporates the entire campus of the former Northampton State Hospital (see Figure 1 — USGS Locus Map). Wetland resource areas were delineated on three distinct parcels located on or near the former hospital site (see the attached existing conditions site plan). Parcel #16, which is owned by the City of Northampton, is adjacent to the Mill River extending from the Earle Street/Route 10 intersection to the Earle Street/Grove Street intersection. Parcel #11 is also owned by the City of Northampton and is situated on the south side of Grove Street across from the former State Hospital property. The Village at Hospital Hill 1 Attachment A - Narrative EpsilonAssociates, Inca Parcel #50 is owned by the Commonwealth of Massachusetts and is situate directly across Grove Street from Parcel 11. Parcel #50 is part of the larger State Hospital site. 3.0 Jurisdictional Wetland Resource Areas On December 4, 2001, project scientists from Epsilon Associates delineated off -site wetland resource areas in close proximity to anticipated Phase 1 redevelopment activities at Grove Street, Earle Street, and Route 10. On -site wetland resource areas were delineated on December 20, 2001, with the assistance of Dr. Peter L. M. Veneman. Wetland scientists from Beals and Thomas, Inc and Epsilon Associates re- visited the delineations on June 7, 2002 and finalized them in light of vegetative growth patterns evident during the growing season. r r Definition Bordering vegetated wetlands (BVW's) are freshwater wetlands that border on } creeks, rivers, streams, ponds and lakes. The types of freshwater wetlands are wet meadows, marshes, swamps and bogs. They are areas where the topography is low and flat, and where the soils are annually saturated. The ground and surface water regime and the vegetational community that occur in each type of freshwater wetland are specified in the Act. The boundary of a t i BVW is the line within which 50 percent or more of the vegetational community consists of the wetland plant species identified in the Act with indicators of hydrology and hydric soils present. 3.1 Bordering Vegetated Wetlands Field Delineation The Village at Hospital Hill 3 In delineating wetland resource areas, project scientists followed the methodology described in the DEP's Handbook on Delineating Bordering Vegetated Wetlands (March 1995), the US Army Corps of Engineers Wetlands Delineation Manual (January 1987), the New England Hydric Soils Technical Committee, Field Indicators for Identifying Hydric Soils in New England, and Section 24:2 of the Ordinance. Three (3) wetland flag series were placed, denoting Bordering Vegetated Wetlands. Each of these flag series is described in the following sections and depicted on Figure 2 - Wetland Resource Areas. Inland bank and Riverfront Area, relative to the Mill River, are described in Sections 3.2 and 3.4 (respectively) and also depicted on Figure 2. Bordering Land Subject to flooding has also been identified, and is discussed in Section 3.3 and depicted on Figure 3 — Flood Hazard Map. Three BVW series (wetland series #1, #2 and #3) were delineated on -site and at off -site locations near the intersection of Grove and Earle Street. Under the Act and Ordinance, there is a 100 -foot Buffer Zone associated with these wetlands. Attachment A - Narrative Epsilon Associates, Inc. r The Village at Hospital Hill Parcel #16: BVW Wetland Series #1 BVW wetland series #1 exists tangent to the western bank of the Mill River, down gradient from Earle Street (see Figure 2 and Sheet 1, Wetland Resource Areas). In this location, the Mill River bank has been fortified with large granite blocks that result in a distinct separation of approximately 25 to 35 feet from the Mill River itself and this wetland (see Figure 4, photograph A). A dam exists where the Mill River flows beneath Route 10. Sixteen pink flags (labeled 1 -1 through 1-16) were tied in the field along the wetland /upland edge. Wetland series #1 may be characterized as forested wetland with a scrub -shrub component (see Figure 4, photograph B). Dominant tree species in the wetland and surrounding buffer zone include cottonwood, red maple, black cherry, American elm, and oak species. The roots of these tree species were exposed and shallow rooted. A seasonal high water table may impede their growth, which is at or near the surface at select times throughout the year. Dominant shrub species included black cherry, redosier dogwood, northern arrow -wood, honeysuckle, poison ivy, goldenrod species, and multiflora rose. Primary hydrology to this wetland is derived from a series of pipes and culverts, which convey stormwater runoff from Earle Street and Route 10, through this wetland system and eventually into the Mill River. According to the Hampshire County Soil Survey (Central Part), soils in wetland series #1 are comprised of Belgrade silt loams (BaB), 3 to 8 percent slopes with areas of Raynham soils (0 to 3 percent slopes). Belgrade soils are moderately well drained and have a slow permeability rate. These soils formed in marine or lacustrine sediments and are typically found along existing streams or rivers including the Mill River. Most areas of these soils were historically farmed with some degree of artificial drainage. The Raynham soil series, which is similar to the Belgrade series, consists of deep, poorly drained soils on old lakebeds. These soils formed in glaciolacustrine deposits and sloped generally range from 0 to 3 percent. Parcel #11: BVW Wetland Series #2 6 BVW wetland series #2 appears to be a formerly cultivated field that has reverted to a wet meadow. Invasive (and non - native) reed canary grass interspersed with meadow fescue is the dominant cover type (see Figure 5, photographs A and B, and Sheet 1). Random apple, willow, and poplar saplings were identified along the edges. Primary hydrology within this wetland is likely attributable to elevated seasonal high groundwater levels and slow permeability rates associated with existing soil types (Belgrade and /or Raynham silt loams). Attachment A - Narrative Epsilon Associates, Inc. li Parcel #50: BVW Wetland Series #3 Definition The Village at Hospital Hill Similar to wetland series #2, this wetland may have historically been a cultivated field that has since reverted to a wet meadow. Reed canary grass was the dominant cover type within the lower elevations of the wetland. Interspersed along higher elevations were willow saplings, bedstraw, dogwood, apple, Kentucky bluegrass, meadow fescue, knotweed, hickory saplings, red clover, catalpa, staghorn sumac, multiflora rose, soft rush, sensitive fern and goldenrod species (see Figure 6, photographs A and B and Sheet 1). Construction of Grove Street likely bisected wetland series #2 from wetland series #3. The juxtaposition of this wetland in the surrounding landscape (e.g., at the base of three hills), the encompassing watershed, and slow soil permeability rates (Raynham silt loam) results in a groundwater discharge condition. Groundwater discharge areas occur typically at the base of slopes (e.g., footslope or toe -of- slope) where groundwater moves towards the land surface and discharges onto or close to the surface. Such a condition is evident in this wetland system, which has a consistent and gradual slope towards Grove Street. This wetland series borders on a narrow intermittent stream channel (adjacent and parallel to the abutting residential building at #91 Grove Street), that appears to convey water from the wetland through a well defined drainage ditch and into a culvert. 3.2 Inland Bank According to 310 CMR 10.54, an inland bank is the portion of the land surface that normally abuts and confines a water body. It occurs between a water body and a bordering vegetated wetland and adjacent floodplain, or, in the absence of these, it occurs between a waterbody and an upland. The upper boundary of bank is the first observable break in slope or the mean annual flood level, whichever is lower. The lower boundary of a bank is the mean annual low flow level. 9 Attachment A - Narrative Epsilon Associates, Inc. Field Delineation Inland bank was identified along the Mill River (approximate mean high water elevation) and the well- defined intermittent stream channels associated with wetland series #2 and #3 (first break in slope). Under the Act and Ordinance, there is a 100 -foot buffer zone associated with this resource area. This buffer zone is coincident with or within the BVW 100 -foot buffer, and is not separately shown on Project site plans. 3.3 Bordering Land Subject to Flooding Definition According to 310 CMR 10.57, bordering land subject to flooding (BLSF) is an area with low, flat topography adjacent to and inundated by flood waters rising from creeks, streams, rivers, ponds, or lakes. The boundary of BLSF is the 100 - year floodplain. It extends from the outer edge of a bank or bordering vegetated wetland. Delineation According to the Federal Emergency Management Agency, Flood Insurance Rate Maps (FEMA -FIRM) (Community Panel #250167 0002, dated April 3, 1978), the Mill River has a Zone A — 100 year flood boundary (i.e., BLSF) with an approximate floodplain elevation ranging between 126 feet and 127 feet NGVD at the Route 10 dam (see Figure 3). 3.4 200 -foot Riverfront Area Definition According to 310 CMR 10.58 (in part), a riverfront area is the area of land between a river's mean annual high water line and a parallel line measured 200 feet horizontally outward. A river means any natural flowing body of water that empties to any ocean, lake, pond, or other river and which flows throughout the year. Perennial streams are rivers; intermittent streams are not rivers. 1 NGVD = National Geodetic Vertical Datum O The Village at Hospital Hill 11 Attachment A Narrative Epsilon,,Associates, Inc. Delineation Definition Delineation 2 See Section 24:9(definitions — resource area) The Village at Hospital Hill 3.5 40 -foot Buffer Zone 3.6 100 -foot Buffer Zone Definition Rivers or streams shown as perennial on the current USGS or more recent map provided by the DEP are presumed to be perennial. If a river or stream is shown as intermittent or not shown on the current USGS map or more recent map provided by the DEP, an assertion that it is perennial must be supported with evidence by the person making the assertion or by the issuing authority upon on its own initiative. According to the applicable USGS locus map (see Figure 1), of the three wetland systems delineated by project scientists, only wetland series #1 borders on a perennial stream or river (i.e., the Mill River). In accordance with the Act, a 200 -foot Riverfront Area has been delineated accordingly from the banks of the Mill River (see Figure 2 and Sheet 1). According to section 24:9 of the Ordinance, lands subject to flooding or inundation have an associated 40 -foot Buffer Zone from their delineated edge. The 40 -foot Buffer Zone is not regulated as a wetland resource area, rather it is the NCC's limit of jurisdiction The Act does not have a 40 -foot or 100 -foot Buffer Zone provision from the edge of BLSF. In accordance with the Ordinance, a Buffer Zone extends from the edge of BLSF associated with the Mill River. It has been depicted accordingly on the attached existing conditions site plan. A Buffer Zone is the area of land extending 100 -feet horizontally outward from the boundary of the following state and local wetland resource areas: • Jurisdictional seasonal wetlands, isolated wetlands, kettle holes; • Bordering Vegetated Wetlands; and • Bank, beach, marsh, wet meadow, bog or swamp. 12 Attachment A - Narrative Epsilon Associates, Inc. Delineation 4.0 Non - Jurisdictional Wetland Resource Areas As noted above, a vegetated slope situated on the uphill side of Earle Street was saturated at the time of inspection but was not considered a jurisdictional wetland resource area (see Figure 2 and Sheet 1). This area was considered a component of the existing stormwater management system, functioning as a "level spreader" where stormwater flows are uniformly spread out over the ground as sheet flow (thus preventing concentrated, erosive flows), rather than a viable wetland. 5.0 Conclusions The applicant requests that the NCC confirm the delineated extent of inland wetland resource areas on the subject parcels which will in turn demarcate the 100 -foot and 40 -foot Buffer Zones as defined under the Act and Ordinance. No work is proposed at this time. As applicable, one or more Notices of Intent describing jurisdictional activities will be filed with the NCC in the future as Phase 1 project design advances. 6.0 Literature Cited The Buffer Zone is not regulated as a wetland resource area under the Act or the Ordinance; rather it is the issuing authority's limit of jurisdiction. The 100 -foot Buffer Zone extends from the edge of each delineated BVW flag series, freshwater wetland and inland bank. It has been depicted accordingly.on the attached site plans. DEP, 1995.

ON Engineers M Environmental Consultants 7.0 WETLANDS, WILDLIFE AND STORMWATER 7.1 Wetland Resources On December 4, 2001, project scientists from Epsilon Associates delineated off -site wetland resource areas in dose proximity to anticipated Phase I work at Grove Street, Earle Street, and Route 10. On -site wetland resource areas associated with the Full Build development scenario were delineated on December 20, 2001, with the assistance of Dr. Peter L. M. Veneman. In delineating the above wetland resource areas, project scientists followed the methodology described in the DEP's Handbook on Delineating Bordering Vegetated Wetlands (March 1995), the US Army Corps of Engineers Wetlands Delineation Manual (January 1987), the New England Hydric Soils Technical Committee, Field Indicators for Identifying Hydric Soils in New England, and Section 24:2 of the Northampton Wetland Protection ByLaw (the ByLaw). Three wetland flag series were placed, denoting vegetated wetlands. Each of these flag series is described in the following section and depicted on Figure 7 -1. Riverfront Area, relative to Mill River, is described in section 7.1.2, and also depicted on. Figure 7 -1. Bordering Land Subject to Flooding has also been identified, and is discussed in Section 7.1.3 and depicted on Figure 7 -3. The Phase I Report is being provided to the Northampton Conservation Commission for its review and comment, and an Abbreviated Notice of Resource Area Delineation (ANRAD) will be filed later this spring for verification of the delineation. A copy of the Commission's ruling will be included in the Draft EIR. 7.1.1 Vegetated Wetlands The majority of the site is situated on a hilltop plateau and is thus devoid of jurisdictional vegetated wetlands. However, project scientists identified and delineated the following on- site and off -site wetland resource areas. Wetland Series #1 Wetland series #1 exists tangent to the western bank of the Mill River, down gradient from Earle Street (see Figure 7 -1). In this location, the Mill River bank has been fortified with large granite blocks that result in a distinct separation of approximately 25 to 35 -feet from the Mill River itself and this wetland (see Figure 7 -2, photograph A). A dam exists where the Mill. River flows beneath Route 10. 766011Phase 1 Reportl7- WetWildStorm.doc 7 - Wetlands, Wildlife and Stormwater Tighe & Bond Epsilon Associates, Inc.

A river means any natural flowing body of water that empties to any ocean, lake, pond, or other river and which flows throughout the year. Perennial streams are rivers; intermittent streams are not rivers. Rivers or streams shown as perennial on the current USGS or more recent map provided by the DEP are presumed to be perennial. If a river or stream is shown as intermittent or not shown on the current USGS map or more recent map provided by the DEP, an assertion that it is perennial must be supported with evidence by the person making the assertion or by the issuing authority upon on its own initiative. According to the applicable USGS locus map (see Figure 2 -1), of the three wetland systems delineated by project scientists, only wetland series #1 borders on a perennial stream or river (i.e., the Mill River). In accordance with the Act, a 200 -foot riverfront area has been delineated accordingly from the banks of the Mill River (see Figure 7 -1). 7.1.3 Bordering Land Subject to Flooding Bordering land subject to flooding (BLSF) is an area with low, flat topography adjacent to and inundated by floodwaters rising from creeks, streams, rivers, ponds, or lakes. The boundary of BLSF is the 100 -year floodplain. It extends from the outer edge of a bank or bordering vegetated wetlands. According to the Federal Emergency Management Agency, Flood Insurance Rate Maps (FEMA -FIRM) (Community Panel #250167 0002, dated April 3, 1978), the Mill River has a Zone A — 100 year flood boundary (i.e., BLSF) with an approximate floodplain elevation ranging between 126 feet and 127 feet NGVD at the Route 10 dam (see Figure 7 -5). 7:2 Wetland Impacts 7.2.1 Full Build 1 NGVD = National Geodetic Vertical Datum 766011Phase 1 Reportl7- WetWildStorm.doc The majority of the Full Build development scenario will not occur within 100 -feet of jurisdictional local and state wetland resource areas (i.e., the "buffer zone "). Access roadways and circulation patterns are still being evaluated and, depending on final design, may result in encroachments into the buffer zone of wetland series #2 and /or direct alteration of wetland series #3. No Phase I activities are contemplated to occur in these locations. • Scanned 7 -7 Wetlands, W i ci..lf ,an Stormwater ' • ghe &-Bond Epsilon Associates, Inc. 1 Section 6 Notice of Intent Plans Earle Street Reconstruction Prepared by Vanasse & Associates, Inc.

PHOTO B: Wetland Series #3, view looking north/northwest. 1 1 Figure 7.4 The Village at Hospital Hill Northampton, Massachusetts Sixteen pink flags (labeled 1 -1 through 1 -16) were tied in the field along the wetland/upland edge. Wetland series #1 may be characterized as forested wetland with a scrub -shrub component (see Figure 7 -2, photograph B). Dominant tree species in the wetland and surrounding buffer zone include cottonwood, red maple, black cherry, American elm, and oak species. The roots of these tree species were exposed and shallow rooted. A seasonal high water table may impede their growth, which is at or near the surface at select times throughout the year. Dominant shrub species included black cherry, redosier dogwood, northern arrow -wood, honeysuckle, poison ivy, goldenrod species, and multiflora rose. Primary hydrology to this wetland is derived from a series of pipes and culverts, which convey stormwater runoff from Earle Street and Route 10, through this wetland system and eventually into the Mill River. According to the Hampshire County Soil Survey (Central Part), soils in wetland series #1 are comprised of Belgrade silt loams (BaB), 3 to 8 percent slopes with areas of Raynham soils (0 to 3 percent slopes). Belgrade soils are moderately well drained and have a slow permeability rate. These soils formed in marine or lacustrine sediments and are typically found along existing streams or rivers including the Mill River. Most areas of these soils were historically farmed with some degree of artificial drainage. The Raynham soil series, which is similar to the Belgrade series, consists of deep, poorly drained soils on old lakebeds. These soils formed in glaciolacustrine deposits and sloped generally range from 0 to 3 percent. Wetland Series #2 Wetland series #2 appears to be a formerly cultivated field that has reverted to a wet meadow. Invasive (and non - native) reed canary grass (Phalaris arundinacea) is the dominant cover type (see Figure 7 -3, photograph A and B). Random apple (Mallus spp.), willow, and poplar saplings were identified along the edges. Primary hydrology within this wetland is likely attributable to elevated seasonal high groundwater levels and slow permeability rates associated with existing soil types (Belgrade and /or Raynham silt loams). Wetland Series #3 Similar to wetland series #2, this wetland may have historically been a cultivated field that has since reverted to a wet meadow. Dominant vegetation includes reed canary grass and other wetland plant species such as willow saplings and steeplebush (see Figure 7-4, photograph A and B). The juxtaposition of this wetland in the surrounding landscape (e.g., at the base of three hills), the encompassing watershed, and slow soil permeability rates (Raynham silt loam) results in a groundwater discharge condition. Groundwater discharge areas occur typically at the base of slopes (e.g., foot slope or toe -of- slope) where groundwater moves towards the land surface and discharges onto or close to the surface. Such a condition is evident in this wetland system, which has a consistent and gradual slope towards Grove Street. 766011Phase 1 Report17- WetWildStorm.doc 7 -4 Wetlands, Wildlife and Stormwater Tighe & Bond Epsilon Associates, Inc.
