An Equal Opportunity Employer M/F/V/H M E M O R A N D U M To: David Veleta, P.E. (Northampton, DPW) Kris Baker, P.E. (Northampton, DPW) From: Matthew A. Taylor, P.E. (GZA) Christopher Baker, P.E. (GZA) Chris Tsinidis, P.E. (GZA) Date: January 28, 2021 File No.: 01.0174343.00 Re: Geotechnical Data Memorandum Engineering Services for Levee Certification Connecticut River Levee System Northampton, Massachusetts In accordance with our agreement (WF7-19-2019) dated July 19, 2019, GZA GeoEnvironmental is pleased to submit this memorandum to the City of Northampton Department of Public Works (DPW), summarizing our geotechnical subsurface exploration data collection efforts for the Connecticut River Levee System. A separate memorandum summarizing the geotechnical exploration data collection efforts for the Mill River Levee System is provided under separate cover. This memo was prepared in accordance with Task 3 of the referenced contract and is subject to the Limitations provided in Appendix A. Unless noted otherwise, elevations reported herein are in reference to the North American Vertical Datum of 1988 (NAVD 88). GZA’s subsurface exploration program was performed to gather the necessary data to fill previously identified subsurface information data gaps within the project record. The program was also intended to obtain additional information to support updated seepage analysis, slope stability analyses, wall stability analyses, and settlement analyses for the System. The results of those analyses, which will be submitted under separate cover, will be used to support the levee system certification and eventual Federal Emergency Management Agency (FEMA) accreditation in under Regulation 44 CFR 65.10. BACKGROUND CONNECTICUT RIVER LEVEE SYSTEM In response to significant flooding events in the 1920’s and 1930’s, the United States Army Corps of Engineers (USACE) designed and constructed flood control works along the Connecticut River to protect the City of Northampton (City), Hampshire County, Massachusetts. The Work was authorized under the Flood Control Act, approved on June 22, 1936, and construction along the Connecticut river was conducted over a series of contracts between December 1938 and June 1942. In 1944, the City accepted responsibility to operate and maintain the Connecticut River Levee System (System) in accordance with the Flood Control Regulations. Refer to Figure 1 for a Locus Map of the System. Refer to Appendix B for relevant System Record Drawings obtained from the 1945 Operations and Maintenance Manual. January 28, 2021 File No. 01.0174343.00 Prelim. Geotechnical Investigation Data Memo Page | 2 Proactive by Design The System protects the eastern part of the City against high water from the Connecticut River and includes 4,580 linear feet of earthen levee from Station (Sta.) 0+00 to Sta. 49+50, with a maximum height of 23 feet. The System begins near the intersection at Pomeroy Terrace and Hancock Streets and heads southeasterly across Ventures Field Road at approximately Sta. 15+00, Hockanum Road at approximately Sta. 31+00, the Old Mill River at approximately Sta. 38+00, the Boston & Maine Railroad Tracks at approximately Sta 42+50, and U.S. Highway Route 5 (Pleasant Street) at approximately Sta 44+75, terminating approximately 500 feet west of U.S. Highway No. 5. The Dike includes two ramps to provide traffic over the Dike at Venturers Field Road and Hockanum Road. The System also includes a Pumping Station with associated floodwalls at the southern portion of the levee system where the former alignment of the Mill River crosses the Dike (Sta. 37+00 to Sta. 39+10). The Northampton Flood Control Pumping station is surrounded by a total of 174 feet of concrete cantilevered floodwall. The maximum wall height occurs next to the Pumping Station where the wall is up to 37 feet high. Two stop-log structures are located along the levee system, one at the Boston & Maine Railroad Tracks, and the other at the U.S. Highway No. 5 crossing. SCOPE OF WORK The Scope of Work for the Connecticut River Levee System Subsurface Exploration Program included the following: 1. Review the available existing subsurface information. 2. Prepare a Drilling Work Plan for review and approval by the USACE. 3. Complete the Subsurface Exploration Program which consisted of fourteen (14) test borings (locations designated CT-1 through CT-14 on Sheets 1 through 8 of Figure 2) to evaluate soil and groundwater conditions. 4. Perform gradation analyses on twenty-one (21) soil samples collected from the test borings to confirm field classifications and assist with developing parameters to be used for the proposed geotechnical engineering analysis. 5. Prepare this geotechnical data memorandum to summarize our findings. SUBSURFACE EXPLORATION PROGRAMS PREVIOUS TEST BORINGS Thirty-six (36) borings and two (2) test pits were completed by the USACE in support of the original design of the Connecticut River Levee System. Below are various excerpts from the Connecticut River Levee System subsurface exploration program that were summarized in a Pre-Inspection Packet (PIP) prepared by GZA/Watermark for the 2010 Periodic Inspection of the System regarding planning and design phase subsurface explorations and subsurface conditions assessments: Subsurface Explorations: The subsurface explorations for the Connecticut River Dike consisted of 25 wash borings with drive sampling methods (BH-1 to BH-4, BH-9, BH-13 to BH-15, BH-22 to BH-27, BH-50 to 59, BH-61), 11 auger borings (FA-50 to FA- 56, FA-59, FA-61, FA-63, FA-64), and two test pits (FT-14 and FT-18). The subsurface explorations for the Northampton Pumping Station and Flood Walls utilized many of the explorations performed for the Connecticut River Dike. However, the USACE revised the soil classifications for twelve of the previously performed explorations in the area of the Pumping Station and Flood Walls (BH-4, BH-13, BH-14, January 28, 2021 File No. 01.0174343.00 Prelim. Geotechnical Investigation Data Memo Page | 3 Proactive by Design BH-25 to BH-27, BH-50 to BH-52, BH-55 to BH-57). The strata breaks on the logs did not appear to change. The change was only in the soil class where samples originally shown as Soil Class 11, 12c, and 12 were changed to a composite Soil Class 8, 10, and 12c, respectively. Three (3) additional wash borings (BH-74, BH-84 and BH-85) were performed in the vicinity of the Pumping Station and Flood Wall alignments. Refer to the Select Record Drawings in Appendix B for previous test boring locations and a subsurface profile with the previous test boring data. As noted in the USACE 2010 Periodic Inspection Report, the majority of the previous test borings were performed prior to the construction of the levee/dike and floodwall. As such, the previous explorations did not sample the materials used to construct the levee/dike. 2019-2020 TEST BORINGS The 2019-2020 test borings were drilled through the dikes/levees and adjacent to the floodwall approximately at 300 to 500-foot intervals from the northern end of the levee near Hancock Street and the southern end of the levee near Pleasant Street (U.S. Route 5). The objectives of the 2019-2020 test borings were: • To obtain information about the embankment and foundation soils to support the geotechnical engineering analyses necessary to support the FEMA levee certification/accreditation effort for the System; and • To determine if the “Existing Organic Fill” layer was removed or left in-place below the System. As a first step, GZA prepared and submitted a drilling work plan entitled “Revised Drilling Work Plan for Subsurface Exploration Program – FEMA Certification Efforts for the Connecticut River and Mill River Levee Systems – Northampton, MA”, dated November 20, 2020 to the USACE for review and approval. The Work Plan was prepared in accordance with the USACE’s ER 1110-1-1807, Engineering and Design, “Drilling in Earth Embankment Dams and Levees”, dated December 2014. The final Drilling Work Plan was approved by the USACE on 11/21/2019. The Work Plan has been provided to the City as separate document and should referred to as needed for additional information. GZA engaged New England Boring Contractors, Inc. (NEBC) of both Glastonbury, Connecticut and Hermon, Maine to perform fourteen (14) test borings (CT-1 through CT-14). The 2020 test borings were performed between the dates of December 12, 2019 and January 14, 2020 from the top of the levee, except for CT-2, CT-5 and CT-11, which were performed on the landside slope of the levee. The 2019-2020 test borings were performed using an ATV mounted drilling rig and a truck mounted drill rig. The borings were advanced using drive-and-wash, cased drilling techniques to depths ranging from 4 to 52.0 feet below ground surface (bgs). Split spoon samples were obtained continuously through the levee fill material at each boring location, and at 5-foot intervals thereafter. Split spoon samples were collected in general accordance with ASTM D1586, the Standard Penetration Test (SPT)1. Upon completion, each boring was backfilled with a cement-bentonite grout mix using a tremie grouting technique. A GZA engineer coordinated with the drilling subcontractor, observed the borings on a full-time basis, classified the soil samples, prepared the daily field reports attached as Appendix C and prepared the boring logs attached as 1 The SPT consists of driving a 2-inch-outside-diameter split spoon sampler a total of 24 inches with a 140-pound hammer free- falling 30 inches. The number of hammer blows required to drive the sampler are recorded for each 6 -inch interval. The number of blows required to advance the sampler from 6 to 18 inches of penetration is referred to as the “N Value”. January 28, 2021 File No. 01.0174343.00 Prelim. Geotechnical Investigation Data Memo Page | 4 Proactive by Design Appendix D. The as-drilled boring locations were located by GZA using a Trimble R1 GPS unit with submeter accuracy. The as-drilled boring location plans are attached as Figure 2. Ground surface elevations were estimated from a plan entitled “PLAN OF LAND IN NORTHAMPTON, MA” prepared by Northeast Survey Consultants, Inc. and dated April 16, 2015. GEOTECHNICAL LABORATORY TESTING Twenty-one (21) soil samples collected from the 2019-2020 test borings were selected by GZA for analysis and submitted to Thielsch Laboratories in Cranston, Rhode Island, for testing. The geotechnical laboratory testing program consisted of gradation analysis to evaluate/confirm field classifications and to support assignment of engineering parameters for use in subsequent geotechnical engineering analyses. Geotechnical laboratory test results are attached as Appendix E. INFERRED SUBSURFACE CONDITIONS SOIL AND ROCK Based on the record drawings, the Connecticut River Levee System construction consists of the same fill materials over four distinct cross sections as shown in Plate VIII of Appendix B as well as one section of flood wall. The cross sections indicate levee/dike embankment construction consisting of Pervious Fill on the landside of the levee/dike and Impervious Blanket Fill on the riverside of the levee/dike, over a core of Random Fill material for the remainder of the embankment. Riprap was placed above the Impervious Fill on the riverside at two locations for a total of about 1,300 feet of levee alignment. All of the 2019-2020 test borings were performed on the top of the levee, with the exception of borings CT2, CT-5 and CT-11, which were performed on the landside slope of the levee. The boring locations were typically alternated between the riverside edge and the landside edge of the top of the levee to capture subsurface data from both the Pervious Fill and Impervious Fill layers. The foundation soils generally consist of alternating layers of impervious, moderately impervious, and pervious materials over varved clay. A general description of each strata/deposit encountered in the 2019-2020 explorations is presented below, in order of increasing depth. Refer to the test boring logs in Appendix D for the conditions encountered in each exploration location. A summary of the subsurface conditions is also provided in Table 1. The foundation soil subsurface conditions encountered in the 2019-2020 borings were generally consistent with the conditions indicated in the previous test boring logs and as shown on the record drawings. Topsoil Fill – An approximate 5- to 24-inch thick layer of Topsoil Fill was encountered at the ground surface at borings CT-2, CT-5, CT-11, and CT-12. The Topsoil Fill predominately consisted of dark brown, SILT, up to 45 percent fine to coarse sand, up to 20 percent roots and other organic material, and up to 10 percent gravel. Gravel Base Course – An approximate 0.5- to 3-foot thick layer of Gravel Base Course was encountered at the ground surface at borings CT-1, CT-3, CT-4, CT-6, CT-6A, CT-7, CT-8, CT-9, CT-10, CT-13, and CT-14 on top of the levee/dike. The Gravel Base Course predominately consisted of brown, fine to medium SAND, up to 45 percent Gravel, up to 35 percent silt. Additionally, over 50 percent of the samples contained up to 15 percent roots and other organic material. The SPT N-values within the Gravel Base Course ranged from 4 blows per foot (bpf) to 28 bpf, indicating variable relative density ranging from loose to medium dense. However, the typical density of the Fill was observed via the SPT to be Medium Dense. January 28, 2021 File No. 01.0174343.00 Prelim. Geotechnical Investigation Data Memo Page | 5 Proactive by Design Pervious Fill – A Pervious Fill layer was encountered below the Topsoil Fill layer in borings CT-3, CT-5, CT-10, and CT-11. The Pervious Fill thickness ranged between approximately 3 feet to 14.1 feet. The Pervious Fill generally consisted of a reddish brown, fine to medium SAND, up to 35 percent Gravel, and up to 10 percent Silt. In general, the Pervious Fill material is similar to the existing weathered sandstone, native to the Connecticut River Valley. The SPT N-values within the Pervious Fill ranged from 10 bpf to 33 bpf, indicating variable relative density ranging from loose to dense. However, the typical density of the Fill was observed via the SPT to be Medium Dense. Impervious Blanket Fill – An Impervious Blanket Fill layer was encountered in test borings CT-1, CT-4, CT-6, CT-6A, and CT-9 below the Gravel Base Course layer on the riverside edge of the top of the levee/dike. The Impervious Blanket Fill thickness ranged between approximately 2 feet to 3.2 feet. The Impervious Blanket Fill generally consisted of brown, SILT, with up to 30 percent fine Sand. The SPT N-values within the fill ranged from 20 bpf to 28 bpf, indicating a Very Stiff relative density. Random Fill – A Random Fill layer was encountered in test borings CT-1, CT-3, CT-4, CT-6, CT-7, CT-8, CT-9, CT-10, CT-12, CT-13, and CT-14 below the Topsoil Fill or Gravel Base Course layers on the landside edge of the top of the levee/dike. The Random Fill thickness ranged between approximately 12 feet to 21.5 feet. The Random Fill generally consisted of brown, SILT, with varying amounts of fine Sand ranging between about 5 to 50 percent, and occasionally greater than 50 percent. The SPT N-values within the Random Fill ranged from 9 bpf to 75 bpf, indicating a highly variable relative density ranging from loose to very dense. However, the typical relative density of the Random Fill was observed via the SPT to be Dense. It is noted that N-values greater than 50 bpf are anticipated to indicate the presence of cobbles or boulders, and do not necessarily represent the relative density of the Random Fill. Existing Organic Fill – An Existing Organic Fill layer was encountered in test borings CT-13 and CT-14 below the Random Fill layer on the levee/dike. It appears the Existing Organic Fill layer was in-place prior to the construction of the levee, hence the “existing” descriptor. This assessment is consistent based on the record drawings. The Existing Organic Fill thickness is approximately 12 feet. The Existing Organic Fill generally consisted of brown to gray ORGANIC SILT or SILT & CLAY, with up to 50 percent fine to medium Sand, and up to 10 percent Gravel. The SPT N-values within the Existing Organic Fill ranged from 4 bpf to 17 bpf, indicating variable relative density ranging from “soft” to “very stiff”. However, the general relative density of the Existing Organic Fill was observed via the SPT to be Medium Stiff. Sand & Silt – A naturally deposited Sand & Silt layer was encountered at test borings CT-1 and CT-7 beneath the Random Fill layer on the levee/dike. The Sand & Silt layer thickness was approximately 2 feet. The Sand & Silt layer generally consisted of a grey, SAND, with up to 45 percent Silt, and up to 10 percent roots. The SPT N-values within the Sand & Silt ranged from 3 bpf to 15 bpf, indicating variable relative density ranging from Very Loose to Medium Dense. Silt & Clay – A naturally deposited Silt & Clay layer was encountered in each test boring, with the exception of CT- 6, CT-6A, and CT-14, beneath the Random Fill or Pervious Fill layers on the levee/dike. The Silt & Clay thickness ranged between approximately 3.5 feet to 13 feet. The Silt & Clay layer generally consisted of a grey, SILT & CLAY, up to 50 percent fine sand, up to 20 percent Gravel, and up to 10 percent roots. The SPT N-values within the Silt & Clay ranged from 0 bpf to 15 bpf, indicating variable relative density ranging from very soft to stiff. However, the typical relative density of the Silt & Clay was observed via the SPT to be Medium Stiff. Silt – A naturally deposited Silt layer was encountered at test boring CT-6 below the Random Fill layer, at test borings CT-7 and CT-11 below the naturally deposited Sand layer, and at test boring CT-9 below the naturally deposited Silt & Clay layer. The Silt layer thickness ranged between approximately 2.5 feet to 17 feet. The Silt layer January 28, 2021 File No. 01.0174343.00 Prelim. Geotechnical Investigation Data Memo Page | 6 Proactive by Design generally consisted of brown SILT & CLAY, up to 45 percent fine SAND, up to 10 percent Gravel. The SPT N-values within the Silt ranged from 1 to 28 bpf, indicating variable relative density ranging from very soft to very stiff. However, the general relative density of the Silt layer was observed via the SPT to be Medium Stiff. Sand – A naturally deposited Sand layer was encountered in each test boring below the naturally deposited Silt & Clay, naturally deposited Silt, and Existing Organic Fill layers. The Sand thickness ranged between approximately 2 feet to 16 feet. The Sand generally consisted of gray, fine to coarse SAND, up to 45 percent Gravel, and varying amounts of Silt ranging between about 5 to 30 percent. The SPT N-values within the fill ranged from 2 bpf to 24 bpf, indicating variable relative density ranging from very loose to medium dense. However, the general relative density of the Sand was observed via the SPT to be Medium Dense. Varved Clay – A naturally deposited Varved Clay deposit was encountered at test borings CT-1 through CT-5, CT- 11, and CT-14, below the naturally deposited Sand layer. The Varved Clay deposit generally consisted of a grey, SILT & CLAY or SILTY CLAY, with alternating 1/16-inch to 1/4-inch thick lenses of a dark grey Clayey Silt and/or a reddish-brown fine to medium Sand. The SPT N-values within the Varved Clay ranged from 0 bpf to 3 bpf, indicating a “very soft” relative density/consistency. GROUNDWATER Water level observations were made during drilling at each borehole. The water levels ranged between approximately 0.3 feet to 12 feet bgs, which correlates to a range between about El 131 feet and El. 113 feet. However, it must be recognized that these water level readings were obtained inside the casing during drilling. Water was added to each borehole as part of the drive-and-wash drilling methods used and water was added to the drill casing at the end of each day to mitigate the potential of soil “blow-in” into the casing, as stipulated in part of the Drilling Work Plan. Therefore, the water levels obtained during drilling are not representative of the actual stabilized groundwater conditions at the site nor the location of the phreatic surface within the levee/dike. The water levels reported on the boring logs are intended to provide qualitative permeability information for the various soil layers/deposits where the bottom of the casing was located at time of each reading. It should be noted that fluctuations in groundwater levels may occur due to seasonal variations in rainfall and temperature, site features, and other factors different from those existing at the time of the explorations and measurements.

GZA GeoEnvironmental, Inc. (GZA) prepared this report on behalf of, and for the exclusive use of our Client for the stated purpose(s) and location(s) identified in the Proposal for Services and/or Report. Use of this report, in whole or in part, at other locations, or for other purposes, may lead to inappropriate conclusions; and we do not accept any responsibility for the consequences of such use(s). Further, reliance by any party not expressly identified in the contract documents, for any use, without our prior written permission, shall be at that party’s sole risk, and without any liability to GZA. STANDARD OF CARE 2. GZA’s findings and conclusions are based on the work conducted as part of the Scope of Services set forth in Proposal for Services and/or Report, and reflect our professional judgment. These findings and conclusions must be considered not as scientific or engineering certainties, but rather as our professional opinions concerning the limited data gathered during the course of our work. If conditions other than those described in this report are found at the subject location(s), or the design has been altered in any way, GZA shall be so notified and afforded the opportunity to revise the report,as appropriate, to reflect the unanticipated changed conditions . 3. GZA’s services were performed using the degree of skill and care ordinarily exercised by qualified professionals performing the same type of services, at the same time, under similar conditions, at the same or a similar property. No warranty, expressed or implied, is made. 4. In conducting our work, GZA relied upon certain information made available by public agencies, Client and/or others. GZA did not attempt to independently verify the accuracy or completeness of that information. Inconsistencies in this information which we have noted, if any, are discussed in the Report. SUBSURFACE CONDITIONS 5. The generalized soil profile(s) provided in our Report are based on widely-spaced subsurface explorations and are intended only to convey trends in subsurface conditions. The boundaries between strata are approximate and idealized, and were based on our assessment of subsurface conditions. The composition of strata, and the transitions between strata, may be more variable and more complex than indicated. For more specific information on soil conditions at a specific location refer to the exploration logs. The nature and extent of variations between these explorations may not become evident until further exploration or construction. If variations or other latent conditions then become evident, it will be necessary to reevaluate the conclusions and recommendations of this report. 6. In preparing this report, GZA relied on certain information provided by the Client, state and local officials, and other parties referenced therein which were made available to GZANat the time of our evaluation. GZA did not attempt to independently verify the accuracy or completeness of all information reviewed or received during the course of this evaluation. 7. Water level readings have been made in test holes (as described in this Report) at the specified times and under the stated conditions. These data have been reviewed and interpretations have been made in this Report. Fluctuations in the level of the groundwater however occur due to temporal or spatial variations in areal recharge rates, soil heterogeneities, the presence of subsurface utilities, and/or natural or artificially induced perturbations. The water table encountered in the course of the work may differ from that indicated in the Report. 8. Recommendations for foundation drainage, waterproofing, and moisture control address the conventional geotechnical engineering aspects of seepage control. These recommendations may not preclude an environment that allows the infestation of mold or other biological pollutants. GEOTECHNICAL LIMITATIONS File No. 01.0174343.00 Page | 2 October 2020 Proactive by Design COMPLIANCE WITH CODES AND REGULATIONS 9. We used reasonable care in identifying and interpreting applicable codes and regulations. These codes and regulations are subject to various, and possibly contradictory, interpretations. Compliance with codes and regulations by other parties is beyond our control. COST ESTIMATES 10. Unless otherwise stated, our cost estimates are only for comparative and general planning purposes. These estimates may involve approximate quantity evaluations. Note that these quantity estimates are not intended to be sufficiently accurate to develop construction bids, or to predict the actual cost of work addressed in this Report. Further, since we have no control over either when the work will take place or the labor and material costs required to plan and execute the anticipated work, our cost estimates were made by relying on our experience, the experience of others, and other sources of readily available information. Actual costs may vary over time and could be significantly more, or less, than stated in the Report. SCREENING AND ANALYTICAL TESTING 11. We collected environmental samples at the locations identified in the Report. These samples were analyzed for the specific parameters identified in the report. Additional constituents, for which analyses were not conducted, may be present in soil, groundwater, surface water, sediment and/or air. Future Site activities and uses may result in a requirement for additional testing. 12. Our interpretation of field screening and laboratory data is presented in the Report. Unless otherwise noted, we relied upon the laboratory’s QA/QC program to validate these data. 13. Variations in the types and concentrations of contaminants observed at a given location or time may occur due to release mechanisms, disposal practices, changes in flow paths, and/or the influence of various physical, chemical, biological or radiological processes. Subsequently observed concentrations may be other than indicated in the Report. ADDITIONAL SERVICES 14. GZA recommends that we be retained to provide services during any future: site observations, design, implementation activities, construction and/or property development/redevelopment. This will allow us the opportunity to: i) observe conditions and compliance with our design concepts and opinions; ii) allow for changes in the event that conditions are other than anticipated; iii) provide modifications to our design; and iv) assess the consequences of changes in technologies and/or regulations.

Refer to the attached site sketch for approximate boring locations. On-Site: Chris Tsinidis (GZA) onsite from 0800 to 1400 hours New England Boring Contractors, LLC (NEBC) onsite from 0845 to 1400 hours Weather: 30s °F, Sunny Visitors: Kris Baker (City of Northampton) Contractor Equipment: ATV Drill Rig Support Truck with Trailer Work Performed: NEBC arrived at Ventures Field at approximately 0845 to begin the subsurface investigation program for the Connecticut River Levee system. NEBC, the City, and GZA met onsite and discussed locations for unloading the drill rig from the trailer. The City indicated that the drill rig could be unloaded at the Pump Station. All agreed and met at the Pump station at 0900 hours, at which point NEBC unloaded the drill rig and left the trailer at the Pump Station. NEBC indicated that they do not anticipate needing the trailer to mobilize to any of the proposed boring locations between CT-1 and CT-12. NEBC mobilized the drill rig to boring location CT-1 by 1030 hours and drilled boring CT-1 from existing ground surface to approximately 14 feet below ground surface. NEBC stopped drilling for the day at approximately 1345 due to the drilling helper needing to leave the site for a personal matter. NEBC stated that tomorrow, 12/13/19, a new helper will be on-site and full days of drilling would be worked moving forward. NEBC filled the casing full of water and capped the casing as means to secure the borehole overnight. Photo 1: ATV track-mounted rig unloaded at Pump Station. Photo 2: NEBC drilling at location CT-1, facing southeast. Photo 3: NEBC drilling at location CT-1, facing southeast. Progress: Boring CT-1 is in progress (Refer to the attached daily quantity sheet draft for drilling quantities completed on this day). One Week Look-Ahead: It is anticipated that drilling will continue on the Connecticut River Levee with CT-1, CT-2, CT-3, etc. Please feel free to contact us with any questions.

On-Site: Chris Tsinidis (GZA) onsite from 0700 to 1630 hours Daniella Roitman (GZA) onsite from 0700 to 1515 hours New England Boring Contractors, LLC (NEBC – Drill Rig 1) onsite from 0700 to 1515 hours New England Boring Contractors, LLC (NEBC – Drill Rig 2) onsite from 0700 to 1630 hours Weather: 30s °F, Cloudy Contractor Equipment: Two ATV Track-Mounted Drill Rigs Two Box Trucks Work Performed: Chris Tsinidis and Kris Baker marked out revised locations for the MR-4 and MR-5 on the Mill River System. Chris Tsinidis will contact NEBC to have another underground utility mark out performed (i.e. Dig-safe) Drill Rig 1 (Dietrich D-50): NEBC mobilized the drill rig to CT-12 and began drilling CT-12 from existing ground surface, to completion at approximately 42 feet below ground surface (bgs). NEBC tremie-grouted boring CT-12 from 42 feet bgs to existing ground surface. NEBC mobilized the drill rig near the trailer in the Pump Station to be mobilized tomorrow, 1/15/20, to the Mill River Levee System. Drill Rig 2 (Mobile B-53): NEBC mobilized continued drilling CT-14 from approximately 34 feet bgs to completion at approximately 46 feet bgs. NEBC tremie-grouted boring CT-14 from 46 feet bgs to existing ground surface. NEBC mobilized the drill rig to CT-13 and began drilling CT-13 from existing ground surface, to completion at approximately 36 feet below ground surface (bgs). NEBC tremie-grouted boring CT-13 from 36 feet bgs to existing ground surface. Photo 1: NEBC Drill Rig 1 drilling at CT-12, facing east. Photo 2: NEBC Drill Rig 2 drilling at CT-13, facing east. Progress: Boring CT-12, CT-13, and CT-14 were completed today. All borings on the Connecticut River Levee System are completed as of today, 1/14/20. Refer to the attached daily quantity sheet draft for drilling quantities completed on this day and the draft quantity summary sheet for total drilling progress to date. One Week Look-Ahead: It is anticipated that drilling will begin on the Mill River Levee System. Drill Rig 1 will mobilize to the northern end of the levee to work on MR-1 to MR-3. Drill Rig 2 will mobilize to the southern end of the levee to drill MR-6 to MR-8. Please feel free to contact us with any questions.
