General: This building has been designed to be zero net energy ready. Building has been oriented for both passive and active solar access and has insulation and air-tightness levels that are expected to exceed EnergyStar Tier III rating. B. HERS Ratings: It is expected that all units shall achieve a HERS rating of 42 or lower without considering a leased photovoltaic system that is proposed for the south-facing roof surface of this building. It is proposed that once the electricity from the leased photovoltaic system is included, a HERS rating for all units of between 0-42 will be achieved. C. Construction Requirements: The building is detailed to minimize air leakage through walls and around windows. This building as a whole as well as each unit shall meet an air tightness minimum of 1.2 air changes per hour at 50 pascals (1.2 ACH 50). This shall be proven by blower door testing at completion. D. Independent Commissioning: Qualified third party commissioning agents will be utilized to confirm energy efficiency levels and air tightness levels required by these specifications. The General Contractor shall bear all costs associated with air tightness testing beyond the final test, which will be paid by the Owner. 1.3 AIR SEALING REQUIREMENTS A. Overview and Location of the Air Barrier: This document provides guidance on how to create an effective pressure boundary around conditioned space. This guide is provided as recommendations and is not to be considered a requirement except that the units all need to meet a maximum air tightness of 1.2 ach at 50 pascals, as verified by testing to be provided by CET near the completion of the project. Building envelopes are to be air sealed at high and low pressure planes to best mitigate stack-effect driven infiltration. 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc. GENERAL REQUIREMENTS 01 00 00 - 2 B. Attic Areas: In attic areas, the air barrier is to be located at apartment ceiling plane (i.e. floor of the attic) consisting of wood framing and gypsum board.

CONSTRUCTION AND DEMOLITION WASTE MANAGEMENT 01 74 00 - 1 SECTION 01 74 00 CONSTRUCTION AND DEMOLITION WASTE MANAGEMENT PART 1 - GENERAL 1.01 DESCRIPTION OF WORK A. This section describes the requirements for the Contractor and all subcontractors to minimize construction waste and debris and to reuse, salvage, and recycle to the greatest extent feasible. B. This section includes a statement of the Owner’s Waste Management Goals, requirements for the development of a draft and final Waste Management Plan, a reference to resources to assist in recycling, and steps for Management Plan Implementation. C. This section specifies certain wastes that are required to be recycled. D. This section specifies obligations for Reporting to the Owner weights of materials recycled and materials not recycled or reused throughout the project. 1.02 INTENT AND WASTE MANAGEMENT GOALS A. The Owner’s waste management goals include increased recycling and conservation of materials. Construction and Demolition (C&D) Wastes have been identified as a particular target for reuse and recycling, for several reasons: 1. C&D debris typically represents a large volume of material; 2. Many of the waste streams generated during building demolition and construction projects are highly recyclable at reasonable prices; 3. Massachusetts has banned landfill disposal of some C&D debris, and expects to ban other C&D debris in coming years. B. The Owner has determined that reducing, to the maximum extent practicable, the amount of waste disposed of in this project is a high priority. The Contractor and subcontractors shall take steps to generate the least amount of waste possible by minimizing waste due to error, poor planning, breakage, mishandling, contamination, or other factors. C. Of the inevitable waste that is generated, as many of the waste materials as economically feasible shall be segregated for reuse, salvage, or recycling, or recycled as mixed debris. In no case shall material be disposed of in a landfill or incinerator where an approved and less costly recycling or reuse alternative exists. Waste disposal in landfills and incinerators shall be minimized and shall be considered the alternative of last resort. 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc. CONSTRUCTION AND DEMOLITION WASTE MANAGEMENT 01 74 00 - 2 D. With regard to these goals the Contractor shall develop, for the Owner’s review and approval, a Waste Management Plan for this Project as described in Section 1.4. 1.03 DRAFT WASTE MANAGEMENT PLAN A. Within 14 calendar days after receipt of Notice of Award of Bid, and prior to any waste removal, the Contractor shall submit a Draft Waste Management Plan to the Architect. The Draft Waste Management Plan shall contain, as a minimum: 1. A written analysis of the project wastes expected to be generated, by type and approximate quantity. 2. Disposal options: The name of all landfill(s) and/or incinerator(s) proposed for trash disposal, the respective tipping fee(s) for each of these disposal options including transportation costs, and the projected cost of disposing of all Project waste in the landfill(s). 3. Alternatives to Landfill Disposal/Incineration: A list of each material proposed to be salvaged, reused, or recycled during the course of the Project, the proposed end use or market for each material, the respective tipping fees for each end use or market (including transportation costs), and the estimated net cost savings or cost increase resulting from recycling each material (versus landfilling or other disposal), taking into account revenue from the sale of recycled or salvaged materials and tipping fees saved due to diversion of materials. 4. The Draft Waste Management Plan shall include, at a minimum, the materials included in Section 1.5 that are required to be reused or recycled. B. Following the submittal of the Draft Waste Management Plan, OWNER and Architect will review the plan and consider the proposed recycling and waste disposal alternatives. The Owner and/or Architect may suggest alternatives to the proposed disposal options in order to increase recycling, reduce costs, or both. 1.04 MATERIALS FOR WHICH RECYCLING IS REQUIRED A. The Owner requires that, as a minimum, the following materials must be considered for recycling, salvage, or reuse during this project: Asphalt Concrete, concrete block, concrete masonry units (CMU), slump stone (decorative concrete block), and rocks Asphalt Concrete Brick Paper, including bond, newsprint, cardboard, mixed paper, packing materials, and packaging Cement Fiber Products, including shingles, panels, siding Paint Rigid Foam 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc.

Completely butter the ends and head of each unit with mortar and shove the unit into place so that mortar squeezes out of the top of the head joint and bed joint. Cut off and scoop out the mortar that extrudes from bed and head joints on outer and inner faces of the wythe. Do not disturb, tap, shove, or push unit once they are laid in their final position. Set large units such that their weight is supported by shims, not the mortar bed. If shims are used, recess at least 1 in. from the face to permit adequate mortar coverage. 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc. MASONRY CLEANING AND RESTORATION 04 90 00-4 I. Strike exterior of mortar joints flush during laying. When mortar is thumbprint-hard on exposed surfaces, tool joints concave with a cylindrical pointing tool slightly larger than the masonry joint to compact the mortar thoroughly. 3.03 MORTAR REMOVAL A. Procedure for removing existing mortar shall be decided upon successful completion of a mockup and approval by the Designer. B. Remove existing mortar by cutting down the center of the joint with power tools and then removing remaining mortar with hand tools. To prevent joint enlargement, do not chip or cut into adjacent masonry. Do not overcut into masonry. C. Remove mortar from joints scheduled for pointing to depths equal to 2-1/2 times their widths, but not less than 5/8 in. Leave no cavities in the existing mortar, and remove all deteriorated mortar. D. Remove mortar from masonry surfaces within raked-out joints to provide reveals with square backs and exposed masonry sides for contact with pointing mortar. 3.04 MORTAR MIXES A. Measurement: Measure cementitious and aggregate material in a dry condition by volume or equivalent weight. Measure materials with an approved device, not by shovel. B. For pointing only, use pre-hydrated mortar prepared as follows: Mix materials in a clean mechanical batch mixer. Thoroughly mix cementitious and aggregate materials together before adding any water. Then mix again adding only enough water to produce a damp, unworkable mix that will retain its form when pressed into a ball. Maintain mortar in this dampened condition for 60 min. Add remaining water in small portions until mortar of desired consistency (somewhat stiffer than bed mortar) is reached. Use within 60 min. of final mixing. Mortar color must match approved mockup mortar color. C. Do not use admixtures in mortar, unless specifically approved by the Designer. 3.05 MASONRY POINTING A. Rinse joint surfaces with water to remove dust and mortar particles. Time application of rinsing so that, at time of pointing, excess water has evaporated or run off, and joint surfaces are damp but free of standing water. B. Apply mortar in successive layers until a uniform depth is formed. Compact each layer thoroughly and allow to become thumbprint-hard before applying next layer. Allow at least 24 hrs to pass between successive stages of mortar application to allow for mortar shrinkage between stages. C. After joints are filled to a uniform depth, place remaining pointing mortar in successive layers of no greater than 1/2 in. depth until flush with exterior face of stone. Fully compact each layer and allow to become thumbprint-hard before applying next layer. Where 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc. MASONRY CLEANING AND RESTORATION 04 90 00-5 existing stones have rounded edges, recess final layer slightly from face. Take care not to spread mortar over edges and onto exposed face. D. When mortar at exterior face is thumbprint-hard, tool to form a concave joint, flush with the face of the stone. Use a cylindrical tool slightly larger than the joint size to compact mortar against stone joint surface. Remove excess mortar from edge of joint by brushing. E. If shrinkage cracks develop because of too fast of a curing, cure mortar by maintaining in a damp condition for not less than 72 hrs. Keep tiles covered with tarpaulins and use a fog spray periodically to maintain moist conditions under the cover. Do not wash the newly pointed mortar with a stream of water. 3.06 FINAL CLEANING A. GENERAL PROCEDURES 1. Test any cleaning compounds in a small inconspicuous area before beginning full-scale mock-up. 2. Cover all existing exposed metal, glass, and other areas as required before cleaning the masonry with any cleaning compounds. Do not use metal scrapers to clean the masonry. Rinse repeatedly with clean water after cleaning to remove all traces of mortar and debris. Protect all exterior finishes, including glass, aluminum, and completed metal flashing work from any damage or staining caused by this work. 3. Perform pH testing of the masonry surface before and after the use of chemical cleaning products to ensure that the masonry surface is left in a pH-neutral state. 4. If using pressure-washing equipment, use pressure washers at minimum pressure required. Hold the nozzle away from the surface. Do not inadvertently etch the masonry. 5. Brush loose debris and dust off surfaces before applying cleaners. END OF SECTION 82 Bridge Street Housing September 28, 2018 Dietz & Company Architects, Inc.

(OTO) has conducted building assessment services at the 15-unit boarding-style residence located at 82 Bridge Street in Northampton, Massachusetts. Building assessment services (conducted on October 6, 2016) included: a Limited Asbestos Screen (LAS) of major building systems, a hazardous materials assessment, and a lead-based paint screen (LBPS) of painted surfaces. We understand the owner of the building (Valley Community Development Corporation (CDC), also the Client) plans to conduct interior renovations and possibly construct an addition to the building. As such, a comprehensive asbestos assessment is required in accordance with the Environmental Protection Agency (EPA) National Emission Standard for Hazardous Air Pollutants (NESHAP) regulation. However, since the building is currently occupied and utilities are active, destructive testing (required by the regulation) is not possible at this time. This report presents the results of a Limited Asbestos Screen (LAS) performed in general accordance with ASTM Standard E2308- 05. A follow-up, comprehensive NESHAP assessment will be required after the building becomes vacant, but prior to the start of planned interior renovations. The LAS included limited sample collection of building materials for laboratory analysis to identify asbestos containing materials (ACM), as well as visual observation of presumed asbestos containing materials (PACM). Samples were collected of accessible building materials suspected to contain asbestos and generally included resilient flooring materials, wall and ceiling materials (plaster), adhesive mastics, and foundation damp- proofing. Analytical results indicate that none of samples collected contain asbestos. Additional evaluation of building materials per EPA NESHAP regulations would be required prior to building renovation or demolition activities. Abatement of ACM or PACM by a Massachusetts licensed asbestos abatement contractor would be required will to renovation or demolition activities. A lead-based paint screen (LBPS) was conducted by analyzing random painted surfaces in the Site buildings to identify possible lead-based paint. Lead concentration results at or above the 1.0 mg/cm2 regulatory standard set by the United States Department of Housing and Urban Development (HUD), and the U.S. Environmental Protection Agency (EPA) are considered to be lead-based paint. The building contained interior and exterior painted components in poor condition, showing signs of peeling or flaking. The majority of painted wood surfaces contain lead-based paint concentrations above 1.0 milligrams per square centimeter (mg/cm2). O’Reilly, Talbot & Okun Page 3 [ A S S O C I A T E S ] Valley Community Development Corporation Limited Asbestos Screen, Hazardous Materials Assessment, and Lead-Based Paint Screen Residential Building – 82 Bridge Street Northampton, Massachusetts Various hazardous materials have also been identified that will require the removal, transportation and disposal as part of the renovation project. The contractor should be informed of the materials and location of these asbestos and hazardous materials to ensure they are properly managed as part of the renovation project. The information provided in this report is subject to the Terms and Conditions as part of our original proposal agreement, and the attached Limitations. BUILDING DESCRIPTION According to City of Northampton Assessor’s records, the building is a two-and-a-half- story, wood-framed residential structure with a full brick/fieldstone basement (approximate 1,902 square feet footprint). Assessor’s records indicate the building was constructed in 1900, but information provided by the owner (Valley CDC) indicates the building was likely built in the late 1700s or early 1800s. The building has aluminum siding (covering older wood clapboard siding) and a pitched gabled roof covered with asphalt shingles. The building is serviced by public water and sewer and is heated with a natural gas fired boiler located in the basement. The building is a 15-unit boarding-style residence with common kitchen space on the first floor, and a total of four shared bathrooms located on the first and second floors. The building has a two-bay attached garage (constructed on a concrete slab-on-grade) on the C-Side1 of the building. Interior building finishes generally include various styles of sheet flooring (observed in common areas and a second floor bedroom) or carpeting (observed in a first floor bedroom) presumably over hardwood floors. A bathroom located on the second floor had ceramic floor tiles. Floor finishes in some areas/rooms may be “built-up” or constructed with multiple flooring finishes in place. Walls and ceilings consist of either plaster or gypsum/joint compound systems. In some areas/rooms, wall and ceiling systems are “built-up” or constructed with more than one system in place. In the first floor common hallway, 12-inch by 12-inch cellulose ceiling tiles were observed. In general, windows were observed to be vinyl replacement style windows (no fibrous glazing compounds observed). The building is heated with recirculating hot water baseboard heaters. The boiler for this system (a high-efficiency Lochinvar Knight boiler) is located in the basement of the building and is fueled with natural gas. Heating system distribution lines observed in the basement were insulated with foam or fiberglass, or were uninsulated. LIMITED ASBESTOS SCREEN (LAS) The Limited Asbestos Screen (LAS) was performed in general accordance with ASTM Standard E2308-05 to generally identify locations where asbestos containing materials (ACMs) and Presumed Asbestos Containing Materials (PACMs) may be present within 1 Exterior walls are labeled A through D in a clockwise manner, with A-Side wall parallel to the main road or street (in this case Bridge Street) O’Reilly, Talbot & Okun Page 4 [ A S S O C I A T E S ] Valley Community Development Corporation Limited Asbestos Screen, Hazardous Materials Assessment, and Lead-Based Paint Screen Residential Building – 82 Bridge Street Northampton, Massachusetts the building. The LAS is not intended to fulfill the requirements of an Environmental Protection Agency (EPA) National Emission Standard for Hazardous Air Pollutants (NESHAP). If renovation activities are planned at the Site that would disturb the suspect ACMs and/or PACMs, a comprehensive asbestos survey (according to the EPA NESHAPs regulation) would be required. Confirmed ACM should be removed and disposed of by a Massachusetts licensed asbestos abatement contractor prior to disturbance. The LAS was conducted by Ms. Christine Arruda (MA License #AI073989) and Mr. Andrew Rolinger (MA License #AI000025) on October 6, 2016. The LAS included the basement, common kitchen (first floor), four bathrooms (first and second floors), common hallways (first, second and third floors), one occupied bedroom on the first floor (AB-corner of the building), and one un-occupied bedroom on the second floor (DA- corner of the building). Representative bulk samples were collected of accessible homogeneous materials. Samples were packaged according to appropriate chain of custody procedures, and forwarded to EMSL Analytical Services, Inc. of Cinnaminson, New Jersey for analysis of asbestos fibers by the polarized light microscopy (PLM) method, EPA 600/R-93/116. EMSL is an American Industrial Hygiene Association/National Voluntary Laboratory Accreditation Program (AIHA/NVLAP) accredited asbestos laboratory, and is licensed by the Massachusetts Department of Labor Standards (DLS). Materials identified by laboratory analysis as containing asbestos fibers are classified as asbestos containing materials (ACM). Additionally, the Massachusetts Department of Environmental Protection defines materials containing any amount of asbestos (less than 1%) be handled as an asbestos containing waste. Homogenous building components were visually classified based on color, texture, application and the age of the building component. Destructive sampling techniques were not used during our survey. ACMs may be located in areas not accessible during our survey, such as beneath floors, in hidden wall cavities, and behind kitchen and bathroom fixtures. ACMs in these areas may only become evident during renovation. Samples of accessible building materials suspected to contain asbestos were collected including: top (accessible) layers of resilient flooring, wall/ceiling plaster, wall/ceiling gypsum and joint compound, blown-in insulation, black dampproofing located on an area of basement stone wall, and roofing materials. There was no destructive sampling performed as part of this assessment. As shown in Table 1 (attached), asbestos was not detected in the materials tested. Analytical laboratory results are attached at the conclusion of this report. Additional materials identified as PACM include components (gaskets, refractory material) which may be located in the boiler in the basement, additional (older) layers of exterior siding, interior flooring, interior wall and/or ceiling materials, and insulation on heating system risers which may be located in walls or cavities not accessed during the LAS. Note that other asbestos containing materials may be present in the building hidden in O’Reilly, Talbot & Okun Page 5 [ A S S O C I A T E S ] Valley Community Development Corporation Limited Asbestos Screen, Hazardous Materials Assessment, and Lead-Based Paint Screen Residential Building – 82 Bridge Street Northampton, Massachusetts walls or chases, or underneath flooring or ceiling finishes not disturbed as part of our limited assessment. LIMITED LEAD-BASED PAINT SCREEN We conducted a random screening of painted surfaces to determine the presence of lead based paint. The lead paint assessment will be conducted using a portable, hand- held X-Ray fluorescence analyzer (XRF). The lead paint assessment was not performed with the intent of obtaining a Massachusetts Regulation Certification of Compliance. The limited sampling will provides the client with a general determination that lead paint is present within the site building. This information may be useful for contractors bidding and performing work and may provide them with the necessary information for compliance with the OSHA Lead in Construction Standard, 29 CFR 1926.62 Exterior Painted Surfaces The majority of the building is covered with aluminum siding. Accessible painted surfaces included the front (A-side) and side (B-side) porches, fire escape stairs, garage doors, and trim. In general, the majority of exterior painted surfaces exceeded the 1.0 mg/cm2, with a maximum level of 26.7 mg/cm2 detected on the day of our screen. Interior Painted Surfaces In general, interior painted surfaces inside the building (flat finish painted walls, i.e., non- trim, non-windowsill surfaces) ranged from 0.00 to 0.02 milligram of lead per square centimeter (mg/cm2). Other painted surfaces (base trim, decorative molding/mantelpieces, doors, doorway trim, windowsills, and other glossy finish painted surfaces) generally exceeded the 1.0 mg/cm2, with a maximum level of 29.1 mg/cm2 detected on the day of our screen. Based on our findings, we recommend consulting a licensed Massachusetts Lead Inspector if occupants of the building are to include children under six years of age. We recommend that regardless of lead paint concentration, contractors disturbing painted surfaces should comply and utilize the work practices and engineering controls identified in the Occupational Safety and Health Administration (OSHA) lead in construction standard (29 CFR 1926.62). HAZARDOUS MATERIALS In addition to Presumed Asbestos Containing Materials, we have identified various hazardous materials that will require special handling and disposal procedures as part of the renovation project. O’Reilly, Talbot & Okun Page 6 [ A S S O C I A T E S ] Valley Community Development Corporation Limited Asbestos Screen, Hazardous Materials Assessment, and Lead-Based Paint Screen Residential Building – 82 Bridge Street Northampton, Massachusetts Polychlorinated Biphenyls (PCBs) OTO observed a fluorescent lighting fixture(s) in the basement of the building. These lighting fixtures contain internal components (i.e. ballast) that require special handling and disposal procedures. The majority of the older light ballast contain PCBs. There are two methods currently available for disposal of PCB-containing ballasts including incineration and disposal. Incineration is typically more expensive. Regardless of the method, documentation must be provided that verifies the proper removal, transportation, and disposal (destruction/incineration) at an approved facility. In general, PCB ballasts must be placed in 55-gallon drums which once filled, the drums shall be closed and properly labeled for temporary storage, transport, and disposal in accordance with all applicable regulations. Drums containing PCB ballasts must be transported to an EPA-approved disposal facility (incinerator). Documentation must be provided that verifies the proper removal, transportation, and disposal (destruction/incineration) at the approved facility. Drums containing non-PCB fluids, ballast or capacitors shall be disposed of at a legally permitted disposal facility. Ballasts that are not labeled “No PCBs” must be removed, packaged and disposed of in accordance with EPA’s Green Lights Program (July 1994) for Lighting Waste Disposal and in compliance with governing regulations. Ballasts labeled “No PCBs” must be presumed to contain di (2-ethylhexyl) phthalate (DEPH). All light fixture ballast require proper handling, transportation and disposal in accordance with the Massachusetts Department of Environmental Protection (MassDEP) Universal Waste regulations. Mercury OTO personnel also observed fluorescent light bulbs for the fixture located in the building. Fluorescent light bulbs/tubes, thermostats and switches known or presumed to contain Mercury vapor or liquid must be removed, packaged, handled, transported and disposed of in compliance with the MassDEP Universal Waste regulations. Handling and disposal of fluorescent light bulbs and thermostats that contain Mercury liquid or vapor should be performed in accordance with the Massachusetts Universal Waste Management Standard (310 CMR 30.1034) as well as EPA’s Resource Conservation and Recovery Act (RCRA) and other governing regulations and requirements. Guidance documents are also available from the EPA (i.e. the 1994 Green Lights Program for Lighting Waste Disposal). If fluorescent lamps become broken or damaged during removal, the broken lamps should be managed as hazardous waste. Chlorofluorocarbons (CFCs) The building does not contain a centralized cooling (air conditioning) system. Rather, window-mounted air conditioning systems would be used for this purpose. Air conditioners, walk in coolers, refrigerators and freezers, and other white good appliances shall have the refrigerants/CFC’s removed before disposal. O’Reilly, Talbot & Okun Page 7 [ A S S O C I A T E S ] Valley Community Development Corporation Limited Asbestos Screen, Hazardous Materials Assessment, and Lead-Based Paint Screen Residential Building – 82 Bridge Street Northampton, Massachusetts The removal and disposal of chlorofluorocarbons is required for all air conditioning units. Removal, transportation and disposal of CFCs must be performed by a qualified and experienced CFC reclamation contractor in accordance with governing regulations (i.e. EPA’s Clean Air Act Amendments) prior to removal and disposal of this equipment. CFC recovery is typically performed by a mechanical or specialty contractor that is licensed by the EPA for CFC refrigerant recycling/recovery. All Federal, state and local regulations must be complied with when abating Freon- containing devices. Reclaimed CFCs must be handled by an EPA-certified refrigerant reclaimer. The name and address of the transporter and the refrigerant reclaimer, the amount of refrigerant recovered and shipped and the date of shipment and date of receipt by reclaimer must be provided at the conclusion of the abatement and demolition project. SUMMARY The LAS included limited sample collection of building materials for laboratory analysis to identify asbestos containing materials (ACM), as well as visual observation of presumed asbestos containing materials (PACM). Samples were collected of accessible building materials suspected to contain asbestos and generally included resilient flooring materials, wall and ceiling materials (plaster), adhesive mastics, and foundation damp- proofing. Analytical results indicate that none of samples collected contain asbestos. Additional evaluation of building materials per EPA NESHAP regulations would be required prior to building renovation or demolition activities. Abatement of ACM or PACM by a Massachusetts licensed asbestos abatement contractor would be required will to renovation or demolition activities. A lead-based paint screen (LBPS) was conducted by analyzing random painted surfaces in the building to identify possible lead-based paint. Lead concentration results at or above the 1.0 mg/cm2 regulatory standard set by the United States Department of Housing and Urban Development (HUD), and the U.S. Environmental Protection Agency (EPA) are considered to be lead-based paint. The building contained interior and exterior painted components in poor condition, showing signs of peeling or flaking, with lead- based paint concentrations above 1.0 milligrams per square centimeter (mg/cm2). A minimal amount of hazardous materials was observed in the Site building that would require special handling and disposal per Local, State, and/or Federal guidelines prior to renovation or demolition. These items included fluorescent lighting (bulbs and a fixture, potentially containing mercury and PCBs, respectively), and general household size and quantities of cleaners, paints, and stains. Additionally, window mounted air conditioning units may be utilized during warmer months; these items along with refrigerators contain chlorofluorocarbons.

(OTO) has conducted an asbestos and hazardous materials assessment of the 15-unit boarding-style residence located at 82 Bridge Street in Northampton, Massachusetts. This assessment supplements a Limited Asbestos Screen (LAS) of the building which was previously conducted by OTO in October of 2016. Our previous screening included limited testing for asbestos containing materials and lead paint. This assessment was performed in general accordance with the Environmental Protection Agency’s (EPA) National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations to prepare the building for renovations within the front portion of the structure and demolition of the rear portion of the structure. Assessment activities were conducted to generally identify locations where asbestos containing materials (ACMs) and Presumed Asbestos Containing Materials (PACMs) may be present within the building. The information provided in this report is subject to the attached Limitations. 2.0 BUILDING DESCRIPTION According to City of Northampton Assessor’s records, the building is a two-and-a-half- story, wood-framed residential structure with a full brick/fieldstone basement (approximate 1,902 square feet footprint). Assessor’s records indicate the building was constructed in 1900, but information provided by the owner (Valley CDC) indicates the building was likely built in the late 1700s or early 1800s. The building has aluminum siding (covering older wood clapboard siding) and a pitched gabled roof covered with asphalt shingles. The building is serviced by public water and sewer and is heated with a natural gas fired boiler located in the basement. The building is a 15-unit boarding-style residence with common kitchen space on the first floor and a total of four shared bathrooms located on the first and second floors. The building has a two-bay attached garage (constructed on a concrete slab-on-grade) on the C-Side1 of the building. 1 Exterior walls are labeled A through D in a clockwise manner, with A-Side wall parallel to the main road or street (in this case Bridge Street) Valley Community Development Corporation Asbestos and Hazardous Materials Assessment Residential Building 82 Bridge Street, Northampton, MA 0069-09-04 2 Interior building finishes generally include various styles of sheet flooring (observed in common areas and a second floor bedroom) or carpeting (observed in a first floor bedroom) presumably over hardwood floors. A bathroom located on the second floor had ceramic floor tiles. Walls and ceilings consist of either plaster or gypsum/joint compound systems. In the first floor common hallway, 12-inch by 12-inch cellulose ceiling tiles were observed. In general, windows were observed to be vinyl replacement style windows (no fibrous glazing compounds observed). The building is heated with recirculating hot water baseboard heaters. The boiler for this system (a high-efficiency Lochinvar Knight boiler) is located in the basement of the building and is fueled with natural gas. Heating system distribution lines observed in the basement were insulated with foam or fiberglass, or were uninsulated. 3.0 SUMMARY OF ASBESTOS ASSESSMENT Representative bulk samples were collected of accessible homogeneous materials. Samples were packaged according to appropriate chain of custody procedures, and forwarded to EMSL Analytical Services, Inc. of Cinnaminson, New Jersey for analysis of asbestos fibers by the polarized light microscopy (PLM) method, EPA 600/R-93/116. EMSL is an American Industrial Hygiene Association/National Voluntary Laboratory Accreditation Program (AIHA/NVLAP) accredited asbestos laboratory, and is licensed by the Massachusetts Department of Labor Standards (DLS). Samples were collected by Mr. Andrew P. Rolinger (MA DLS Asbestos Inspectors AI 000025). Materials identified by laboratory analysis as containing asbestos fibers are classified as asbestos containing materials (ACM). Homogenous building components were visually classified based on color, texture, application and the age of the building component. The majority of building is currently occupied. As such, limited destructive sampling techniques were used during our survey, where feasible. ACMs may be located in areas not accessible during our survey, such as beneath floors, in hidden wall cavities, in inaccessible areas, and in other enclosed spaces. ACMs in these areas may only become evident during renovation or demolition. In accordance with state and federal regulations, materials that are tested to contain 1% and greater of asbestos will be classified as ACM. Additionally, the Massachusetts Department of Environmental Protection defines materials containing any amount of asbestos (less than 1%) be handled as an asbestos containing waste. 4.0 ASBESTOS TESTING RESULTS Laboratory analytical results are attached and summarized in Table 1. As indicated, laboratory analysis has identified asbestos fibers in the following materials: · Caulking Materials on Exterior Siding and Window Openings Valley Community Development Corporation Asbestos and Hazardous Materials Assessment Residential Building 82 Bridge Street, Northampton, MA 0069-09-04 3 Table 2 Approximate Asbestos Quantities MATERIAL QUANTITY Exterior Siding/Window Caulk 150-200 Linear Feet (on Rear Siding Seams), Plus approximately 40 Window Openings Asbestos was not detected in plaster finishes, in gypsum wallboard or associated joint compound materials, in textured ceiling skim finishes, in resilient flooring materials and associated mastics, in suspended or spline ceiling tiles, in blown-in insulation, in cove base materials, in ceramic tile adhesive or grout, in stair treads, dampproofing materials, or in roofing materials. Note that other asbestos containing materials may be present in the building hidden in walls or chases, underneath flooring, or above ceilings not disturbed as part of our assessment. 5.0 HAZARDOUS MATERIALS 5.1 LEAD PAINT SCREENING In October of 2016, OTO conducted a random screening of painted surfaces to determine the presence of lead based paint. The lead paint testing was conducted by analyzing painted surfaces with a portable x-ray fluorescence (XRF) analyzer. The lead paint assessment was not conducted by a licensed Massachusetts Lead Inspector, nor was the lead paint screening performed in accordance with the Massachusetts Lead Regulations with the intent of obtaining a Massachusetts Lead Regulation Certification of Compliance. In general, concentrations of lead in paint that exceed 1.0 mg/cm2 are classified as dangerous by the EPA. Exterior Painted Surfaces The majority of the building is covered with aluminum siding. Accessible painted surfaces included the front (A-side) and side (B-side) porches, fire escape stairs, garage doors, and trim. In general, the majority of exterior painted surfaces exceeded the 1.0 mg/cm2 action level, with a maximum level of 26.7 mg/cm2 detected on the day of our screen. Interior Painted Surfaces In general, interior painted surfaces inside the building (flat finish painted walls, i.e., non- trim, non-windowsill surfaces) ranged from 0.00 to 0.02 milligram of lead per square centimeter (mg/cm2). Other painted surfaces (base trim, decorative molding/mantelpieces, doors, doorway trim, windowsills, and other glossy finish painted surfaces) generally Valley Community Development Corporation Asbestos and Hazardous Materials Assessment Residential Building 82 Bridge Street, Northampton, MA 0069-09-04 4 exceeded the 1.0 mg/cm2 action level, with a maximum level of 29.1 mg/cm2 detected on the day of our screen. Supplemental Lead Paint Screening, September 2018 At the request of Client, OTO conducted supplemental testing of painted fireplace mantles in units 2A, 2B, 3A, 3B, 6A, and 7A, and a painted mirror in the first floor hallway. In general, painted mantles in Units 2B, 3B, 6A, 7A, exhibited lead concentrations exceeding the 1.0 mg/cm2 action level, with a maximum level of 41 mg/cm2 detected. Painted mantles in Units 2A, 3A exhibited lead concentrations below the 1.0 mg/cm2 action level, with a maximum level of 0.04 mg/cm2 detected. Lead was not detected in the painted hallway mirror located on the first floor. Based on our findings, we recommend consulting a licensed Massachusetts Lead Inspector if occupants of the building are to include children under six years of age. We recommend that regardless of lead paint concentration, contractors disturbing painted surfaces should comply and utilize the work practices and engineering controls identified in the Occupational Safety and Health Administration (OSHA) lead in construction standard (29 CFR 1926.62). 5.2 PRODUCTS CONTAINING PCBs OTO observed a fluorescent lighting fixture(s) in the basement of the building. These lighting fixtures contain internal components (i.e. ballast) that require special handling and disposal procedures. The majority of the older light ballast contain PCBs. There are two methods currently available for disposal of PCB-containing ballasts including incineration and disposal. Incineration is typically more expensive. Regardless of the method, documentation must be provided that verifies the proper removal, transportation, and disposal (destruction/incineration) at an approved facility. In general, PCB ballasts must be placed in 55-gallon drums which once filled, the drums shall be closed and properly labeled for temporary storage, transport, and disposal in accordance with all applicable regulations. Drums containing PCB ballasts must be transported to an EPA-approved disposal facility (incinerator). Documentation must be provided that verifies the proper removal, transportation, and disposal (destruction/incineration) at the approved facility. Drums containing non-PCB fluids, ballast or capacitors shall be disposed of at a legally permitted disposal facility. Ballasts that are not labeled “No PCBs” must be removed, packaged and disposed of in accordance with EPA’s Green Lights Program (July 1994) for Lighting Waste Disposal and in compliance with governing regulations. Ballasts labeled “No PCBs” must be presumed to contain di (2-ethylhexyl) phthalate (DEPH). All light fixture ballast require proper handling, transportation and disposal in accordance with the Massachusetts Department of Environmental Protection (MassDEP) Universal Waste regulations. Valley Community Development Corporation Asbestos and Hazardous Materials Assessment Residential Building 82 Bridge Street, Northampton, MA 0069-09-04 5 5.3 PRODUCTS CONTAINING MERCURY OTO personnel also observed fluorescent light bulbs in fixtures located within the building. Fluorescent light bulbs/tubes, thermostats and switches known or presumed to contain Mercury vapor or liquid must be removed, packaged, handled, transported and disposed of in compliance with the MassDEP Universal Waste regulations. Handling and disposal of fluorescent light bulbs and thermostats that contain Mercury liquid or vapor should be performed in accordance with the Massachusetts Universal Waste Management Standard (310 CMR 30.1034) as well as EPA’s Resource Conservation and Recovery Act (RCRA) and other governing regulations and requirements. Guidance documents are also available from the EPA (i.e. the 1994 Green Lights Program for Lighting Waste Disposal). If fluorescent lamps become broken or damaged during removal, the broken lamps should be managed as hazardous waste. 6.0 CONCLUSIONS Based on sampling and analytical results, we have identified Asbestos Containing Materials (ACM). These materials must be removed according to federal and state abatement/removal regulations by a licensed Massachusetts Asbestos Abatement Contractor prior to renovation or demolition activities if they are likely to be disturbed as part of these activities. Asbestos containing materials that will not be disturbed does not require removal as part of the asbestos regulations.

This inspection was implemented to assess the health and structural integrity of the trees marked for preservation, the impacts the new construction may have on them, and what measures will be needed to protect them during construction. As you recall, I visited the site and met with Berkshire Design’s Chris Chamberland and Laura Baker from Valley CDC on August 17th at which time we discussed the project, reviewed Plans L-101, L -200 and L-300 and identified the trees on site that are to be protected during construction. The following report contains a summary of my findings, photographs of the site and recommendations for further action. Thank you for the opportunity to assist the Berkshire Design Group with this project. Please don’t hesitate to contact me if you have any questions or need additional services. Best regards, David Hawkins, Consulting Arborist Urban Forestry Solutions, Inc.

Page 3 of 11 Site Illustration Plan L-101 with tree locations and approximate protection areas outlined in blue. Note: the blue ‘X’ indicates a tree originally scheduled for protection but removed prior to my site visit. The red ‘Xs’ represent trees recommended for removal Introduction The Sargent House – an affordable living residence, is scheduled for renovation which will involve expansion into some of the landscaped areas surrounding the building. This will result in the removal of some trees and shrubs - mainly in the property’s interior. There are however four areas designated on the property’s edge where trees are to be preserved and protected during the construction process. The four areas were inspected and assessed on August 17th by Urban Forestry Solutions, Inc. to determine tree health, construction impact and what protection measures would be needed. The following report lists each area highlighted in the Site Illustration (above), describes the existing conditions, possible construction impacts and recommendations for further action. Area 1 Area 4 Area 3 Area 2 The Berkshire Design Group Tree Assessment and Recommendations Report: August 24, 2018 Attn: Mr. Carlos Nieto-Mattei Sargent House, 82 Bridge St. Northampton Prepared by: David Hawkins, Consulting Arborist Urban Forestry Solutions, Inc. Page 4 of 11 Area 1 Location: Southwest edge of property bordering and in existing driveway. Species: American elm (Ulmus americana). 50+ inches DBH; ~ 75 feet tall. Another tree was also marked on the L-101 plan as to be protected. This tree was removed prior to the August 17th inspection. Condition: Fair/Good. Some deadwood and dieback in the upper crown. Two to three large leaders were removed on the southeast side leaving the crown somewhat visually unbalanced. Comments: This is a large, old tree growing next to and under the driveway. The recent pruning was presumably done to accommodate new construction on the abutting property. The top dieback may be a result of root loss, damage or dieback from environmental stress. This dieback appears to be relatively recent and may correlate with the timing of the new construction next door. There is also visual evidence of some root activity in form of some minor asphalt heaving under the existing driveway which is scheduled to be re-paved. Recommendations: • Determine scope of root damage if possible. • Apply a root promoting fertilizer within root zone on both properties • Water root zone during extended dry periods • Prune deadwood • Install 10 foot 2 by 4s in a ‘tepee’ arrangement on the north side of the trunk to protect from incidental equipment contact. Boards should be installed so that only the tops are in contact with the tree. Burlap should be installed between tree trunk and contact point. • Install orange snow fence on outside of 2 by 4 protection to increase visibility. • Lay down steel plates on driveway over heaved areas to distribute weight of construction vehicles during the length of the project • Once construction is completed, remove asphalt over root system with care (using hand tools if necessary) to protect roots under asphalt surface • Monitor tree for health and insect and disease infestations over the next few growing seasons.

Page 5 of 11 Area 1 Photographs View looking south at the elm and new construction next door Minor asphalt heaving from the elm’s roots Area 2 Location: North corner of property. Species: ten trees total. Canadian hemlock (Tsuga canadensis); eastern white pine (Pinus strobus); Norway maple (Acer platanoides). Sizes range from 6 inches to 27 inches DBH and 25 to 80 feet in height. Condition: Ranging from poor to good. Three of the 10 trees are poor condition with extensive dieback and/or significant trunk decay. One large pine (35 in. DBH) appears healthy but has a pocket of decay at about 20 feet on the tree’s north side and a ~15- degree lean to the south. Comments: the trees in poor condition consist of one 27-inch hemlock, and a 6 and 9- inch pine. The hemlock is about 85 percent dead and probably will not survive the next growing season. One of the 2 pines is dead, the other has significant trunk decay. The Berkshire Design Group Tree Assessment and Recommendations Report: August 24, 2018 Attn: Mr. Carlos Nieto-Mattei Sargent House, 82 Bridge St. Northampton Prepared by: David Hawkins, Consulting Arborist Urban Forestry Solutions, Inc. Page 6 of 11 The location of the decay and lean on the 35-inch pine may increase the chance of tree failure in severe weather. Construction impact should be minimal and limited to soil compaction in the root zone outside of the TPZ. Recommendations: • Remove the hemlock and two pines • Further inspect the decayed area of the pine, or consider removing tree • Install a semi-permanent 6-foot chain link fence 15 to 20 feet from the remaining group of trees to delineate the tree protection zone (TPZ). Place signage on fence to identify tree protection zone and prohibit fence relocation or storage of materials and equipment inside of TPZ • Install 4 to 5 inches of woodchip mulch in areas of the lawn outside of the TPZ that may be traveled on by construction equipment Area 2 Photograph View looking north with recommended removals identified The Berkshire Design Group Tree Assessment and Recommendations Report: August 24, 2018 Attn: Mr. Carlos Nieto-Mattei Sargent House, 82 Bridge St. Northampton Prepared by: David Hawkins, Consulting Arborist Urban Forestry Solutions, Inc. Page 7 of 11 Area 3 Location: East edge of property opposite building. Species: Hedge row of multiple species growing on or near the property line including invasive vines. Tree species include Norway maple, basswood (Tilia americana) and hemlock. Condition: Ranging from fair to good. One tree is heavily infested with bittersweet. Comments: These trees provide a natural buffer between the two properties. A wooden deck is proposed in the area where the existing fire escape stairs are and will extend to 10 feet of the property line. This will be within the area of the trees’ root systems and recommended TPZ. However, the deck will be construction on pilings which should limit excessive root damage or loss. Prior to the deck’s installation, it is possible the area between the building and trees will be used for equipment access. Soil compaction and root damage is a concern. A row of arborvitaes is proposed within 5 of the hedgerow trees after the deck is constructed. Excavation during the planting process could cause significant root damage. Recommendations: • Remove bittersweet infested tree • Install a semi-permanent 6-foot chain link fence 15 feet west of property line prior to deck’s construction. Place signage on fence to identify tree protection zone and prohibit fence relocation or storage of materials and equipment inside of TPZ • Install 4 to 5 inches of woodchip mulch in area between fence and building to mitigate compaction from construction equipment • Relocate TPZ fence to accommodate deck construction • Deck pilings should be positioned to affect minimal root damage • Consider planting arborvitae hedge on a raised berm to limit root damage or install a privacy fence.

Page 9 of 11 Area 4 Location: Northeast corner of property near Bridge Street. Species: 3 hemlocks – 9, 12 and 9 inches trunk diameter and one 8-inch diameter yew (Taxus cuspidate). Condition: Hemlocks are in fair condition and the yew is in good condition Comments: these trees also provide a vegetation buffer between the two properties although the effectiveness of the hemlocks is less than the yew due to sparse lower limbs and thin crowns most likely to the Hemlock Wooley Adelgid and Elongated Hemlock Scale. Construction impact should be minimal and limited to soil compaction in the root zone outside of the TPZ. Recommendations: • Install a semi-permanent 6-foot chain link fence 10 feet west of property line prior to Place signage on fence to identify tree protection zone and prohibit fence relocation or storage of materials and equipment inside of TPZ • Install 4 to 5 inches of woodchip mulch in area between fence and building to mitigate compaction from construction equipment Area 4 Photograph Northeast view the hemlock and yew trees The Berkshire Design Group Tree Assessment and Recommendations Report: August 24, 2018 Attn: Mr. Carlos Nieto-Mattei Sargent House, 82 Bridge St. Northampton Prepared by: David Hawkins, Consulting Arborist Urban Forestry Solutions, Inc. Page 10 of 11 Disclaimer By the nature or their size, weight and miscellaneous structure, constant exposure to the weather and the elements, susceptibility to insect’s pest and decay organisms, use as homes to birds and animals and other reasons, trees always pose an inherent degree of hazard and risk from breakage, failure and other causes and conditions. Recommendations made by Urban Forestry Solutions, Inc. are intended to minimize, reduce or eliminate hazardous conditions associated with trees. However there is not, and can never be, any guarantee or certainty that these recommendations will totally correct unsafe conditions or prevent failure or breakage of a tree, or that conditions will not change. The recommendations carried out as stated, should reduce the risk but they cannot completely eliminate it (except when the tree is removed), especially in the event of future growth, further deterioration, subsequent insect attacks, extreme weather conditions, eternal factors, (lightning strikes, fallen objects, vehicular damage, act.), storms or other acts of God or man.

EcoFoot5D General Application Notes Site-Specific System Design: Ecolibrium Solar provides drafting services on all EcoFoot5D projects. This service produces a site-specific design package with an Engineered Stamped Layout including detailed ballast plan and bill of materials. Roof Type: EcoFoot5D is designed to mount photovoltaic modules to a range of roof surfaces, including: EPDM, TPO, PVC, Mineral Cap Sheet (a.k.a. Rolled Asphalt), Tar and Gravel. Roof Slope Range: 0-7 degrees maximum, 3-degree limit for unattached seismic. Wind Zone: EcoFoot5D is designed to mount photovoltaic modules on flat roof surfaces with a maximum pitch of 7 degrees in areas with extreme wind conditions. Please contact Ecolibrium Solar for clarification or assistance. Installation Requirements: EcoFoot5D is a ballasted photovoltaic racking designed as a system. The system requires all EcoFoot5D components, the specific module, and ballast placement prescribed in the PE stamped design. The absence of any of these elements in any given sub-array could present a compromised condition on the roof. Arrays shall not be left unattended in such a state during an installation. EcoFoot5D Install Guide V1.1-FINAL Page 6 of 19 January 25, 2018, ES10560 ecolibriumsolar.com This install guide officially documents the components used and proper methods for an EcoFoot5D installation. Bonding elements are incorporated into EcoFoot5D components. As the system is built on the roof, components and modules are bonded together. Specific steps to ensure a bonded system are described through the installation guide. It is the installer’s responsibility to ensure that the system is safely and properly installed, and that the system is bonded back to a final ground point. When wiring the array, keep bare copper from contacting bare aluminum. Thermal and Seismic Design Requirements: EcoFoot5D is a flexible and expandable design that accommodates various array geometries. Maximum widths for arrays are as follows: • 60-cell modules, 26 modules in a row • 72-cell modules, 22 modules in a row Minimum spacing between sub-arrays is 6”. Site specifics may further limit array sizes and spacing. Seismic and Uplift Design Requirements: EcoFoot5D can be attached when required by seismic and uplift conditions as specified by the Authority Having Jurisdiction (AHJ). Addendums in this install guide document the components used and proper methods for an EcoFoot5D installation with attachments. Use the method required for the specific Fire Code Rating of the PV module. Re-Inspection: Ecolibrium Solar recommends periodic re-inspection of the installation for loose components, loose fasteners, and any corrosion, such that if found, the affected components are to be immediately replaced. Compatible Modules: Ecolibrium Solar has evaluated many photovoltaic modules for installation compatibility with the EcoFoot5D ballasted racking system. A list of compatible modules may be found in “EcoFoot5D Install Guide Appendix - Compatible Modules.pdf” on our website: www.ecolibriumsolar.com UL2703 Qualification: In cases where UL 2703 certification is required, the EcoFoot5D system conforms to the UL2703 Standard for grounding and bonding and fire ratings. The EcoFoot5D system may be used to ground and/or mount a PV module complying with UL1703 only when the specific module has been evaluated for grounding and /or mounting in compliance with the included instructions. EcoFoot5D Racking maintains a Class A fire rating when installed in landscape orientation according to the installation instructions, on a low slope roof Class A roof with Type 1 and Type 2 modules. When installing Type 2 modules a Ballast Tray is required. For roofs with lower fire ratings, the existing rating is maintained when EcoFoot5D is used. At this time, the EcoFoot5D system is undergoing further testing pertaining to mechanical loading with specific modules.

Each size supports specific design loads, while minimizing material costs. Depending on your location, there is an XR Rail to match. XR1000 is a heavyweight among solar mounting rails. It’s built to handle extreme climates and spans 12 feet or more for commercial applications. XR100 is the ultimate residential mounting rail. It supports a range of wind and snow conditions, while also maximizing spans. XR10 is a sleek, low-profile mounting rail, perfectly matched to regions with light or no snow. It achieves 6 foot spans, while also staying light and economical.

CAMO is an invisible fastener that secures solar modules flush to rail ends, creating a clean, sleek appearance. CAMO works with nearly all solar modules and installs without tools or torque specifications. It simply rotates into place to structurally secure and electrically bond with the module. Hidden End Cam Certified to comply with International Building Code, ASCE/SEI-7, and UL 2703 Mechanical and Bonding Requirements. Cam-Locking Design CAMO’s unique design allows for a completely tool-less installation. Simply slide CAMO into the rail track and rotate the ergonomic handle 90 degrees to lock onto the module frame. It’s that easy. Standard Fastener © 2018 IronRidge, Inc. All rights reserved. Visit www.ironridge.com or call 1-800-227-9523 for more information. Version 1.01 Tech Brief Easy, Tool-Less Installation A. PLACE CAMO Slide CAMO into rail track far enough to clear the module frame. CAMO requires 6” of clearance from end of rail. B. PLACE MODULE Place module on rails and align flush with rail ends (module cells not shown in image to provide clarity). The module can overhang the rail no more than 1/4”. C. SLIDE CAMO Pull CAMO towards rail end, at a 45 degree angle, so linear bonding pin contacts the module flange edge. D. SECURE CAMO Rotate handle with an upwards motion until CAMO snaps into rail track. Ensure CAMO bonding pins are fully seated on top of module frame. A Tested & Certified B C D UL 2703 CAMO conforms to STD UL 2703 (2015) requirements and fits modules with bottom flanges that meet specifications shown in the frame compatibility diagram on the left. See IronRidge Installation Manuals for full ratings and a list of certified compatible modules.
