will revise the document and provide the City and NHDOT with the Final CE (electronic file and
up to three hardcopies).

Resource Agency Coordination — MJ will attend one NHDOT Natural Resource Agency
Coordination Meeting and two Cultural Resource Agency Coordination Meetings to obtain input
on resource concerns and proposed impacts. MJ will provide agenda item request materials to
request attendance at each meeting. It is anticipated that two MJ staff members will attend
these meetings and that MJ will provide presentation materials and meeting minutes.

Phase 2D — Right of Way Plans

Using the General Plans as a base plan, easement plans will be developed for the parcels
impacted within the project limits. Temporary easements are anticipated on the following
parcels to account for sidewalk and walkway reconstruction.

Parcel 40-1 — 49 Bridge Street
Parcel 40-2 — 51-53 Bridge Street
Parcel 40-4 — 55 Bridge Street
Parcel 40-15 — 136 East Hollis Street
Parcel 40-16 — 144 East Hollis Street
Parcel 40-26 — 152 East Hollis Street
Parcel 40-27 — 154 East Hollis Street
Parcel 40-28 — 156 East Hollis Street

Temporary easements will be shown in color and will be described using roadway stationing,
offset, bearings, and distances. It is assumed a Draft set of plans will be submitted for the
purpose of City staff discussing impacts with owners. Once the owner meetings have taken
place, any proposed revisions will be made and final easement plans submitted to the City.
Since only temporary easements are required, easement plans will not be stamped by Licensed
Land Surveyor.

It is assumed that the City will complete all other aspects of the right-of-way acquisition process.
It is assumed that the City will utilize the Waiver Valuation process defined by NHDOT and will
complete the right-of-way acquisition process by developing the just compensation for the
easements, negotiating with the land owners, and completing the necessary paperwork to
secure the easements in advance of the project’s advertisement date.

Phase 2E — Public Involvement

Public Involvement for the project will continue through the Preliminary Design phase. It is
assumed that MJ will meet with the Project Steering Committee up to three (3) times to update
the committee on project progress and receive guidance. MJ staff (2) will attend and facilitate
these meetings. MJ will generate meeting notes that will be distributed after each meeting.

Public Informational Meeting — Public Information Meeting will be held prior to completing
Preliminary Design to provide the public an opportunity to make final comments or suggestions
on the proposed streetscape elements. Color Hearing Plan type plan view project graphics will
also be displayed for public viewing before and after the meeting. 3D visualizations of the
project are not included.

MJ will continue to update the project website with meeting information and project documents
through the Preliminary Design Phase.

Phase 2F — Utility Coordination

MJ will conduct coordination efforts with private utility companies. Existing underground utilities
include sanitary sewer, natural gas, water, and underground power. Existing overhead utilities
include power, CATV, and telecommunication lines. MJ will be responsible for coordinating
meetings with utility companies and performing the following tasks:

e After the boring program has been completed, the existing utility information shown on
the base mapping, which was collected during Phase 1, will be compared against the
Dig Safe markings placed in advance of the boring program.

e The existing utility information will then be updated with any corrections or clarifications
provided by the utility companies.

e MJ will prepare a list of conflicts for each utility and distribute to the utility companies so
they can develop their utility relocation design.

e It is assumed that two (2) utility coordination meetings will be held to describe the
project, the utility conflicts, and the work required for the utility companies to design the
relocations.

e Once the location of relocated utility poles has been finalized, MJ will show the proposed
utility relocations on the project plans. It is assumed the utility owners will provide their
own relocation designs.

e MJ will prepare meeting notes for the utility coordination meetings and provide on-going
project correspondence via e-mail or telephone communication.

It is assumed that placing existing overhead utility lines underground will not be part of the
project. However, MJ will coordinate with the Eversource on the layout for the underground
lighting conduit for the pedestrian scale lighting and traffic signals.

Phase 3 — Final Design

Upon written approval of the Preliminary Design from the City and NHDOT, Final Design will
begin.

Phase 3A - Environmental Permitting

Shoreland Permit - Portions of the project are located within the Protected Shoreland of
the Merrimack River and it is assumed that proposed work will require a Shoreland
Permit from NHDES. A Shoreland Permit application package will be prepared and will
include Shoreland Impact Plans, application form, project narrative, photographs and
location map. The application package will be submitted to the City for review. After
making requested revisions, MJ will submit the final application package to NHDES.

Alteration of Terrain Permitting and Erosion Control Plans - As the project is within the
protected shoreland of the Merrimack River and will disturb more than 50,000 sq ft of
earth during the roadway and sidewalk reconstruction, it is assumed that the project will
require an Alteration of Terrain Permit from NHDES. MJ will meet with NHDES to
present the project and determine permit requirements. It is assumed that there will be
one meeting at NHDES. This meeting will occur as early in the process as possible. MJ
will prepare the necessary plans, narrative, and application materials for submission to
the City for review. After making requested revisions, MJ will submit the final application
package to NHDES. As part of the AOT application process, MJ will also prepare a
wildlife habitat assessment and consult with NH Fish & Game in accordance with current
regulations.

Any permit fees associated with permit filing will be the responsibility of the City.

Phase 3B — Plans, Specifications and Estimates

The plans developed in the Preliminary Phase will be further enhanced based on comments
received from the City and NHDOT. All plans will be completed to a 95% complete level.

Specifications and Special Provisions — It is assumed the City will provide typical “front end”
General Conditions for this project. MJ will review the City’s General Conditions and prepare
Supplemental Conditions appropriate for this project. It is further assumed that the NHDOT
Standard Specifications will be used as a basis for material specifications for the Contract
Documents. As needed, special provisions will be developed for incorporation into the project
specifications. The specifications for traffic equipment will specify Eagle Brand equipment and
Eagle Brand compatible equipment, video detection, fiber optic cable communication, signal
heads with retroreflective backplates, and mast arms, poles, and cabinets that are painted
glossy black. MJ will prepare a Public Interest Finding for NHDOT approval to specify
proprietary traffic signal items. MJ will also develop written Prosecution of Work and Traffic
Control Plan documents.

Estimates and Quantity Tabulation — An engineer’s opinion of probable cost will be provided. It
is assumed that detailed quantity summary sheets (like those generally prepared for NHDOT)

will not be provided. However, a tabulation of all bid items with the estimated probable unit cost
for each item will be developed for use by the City. A bid form, in a format suitable to the City,
will be provided as part of the Contract Documents for use by the City and its bidders. As noted
above, the estimate should not be construed as an actual price for construction, but merely the
best opinion as to the probable cost of construction. MJ will provide a copy of the quantity
calculations with the final submission of Contract Drawings.

Phase 3C — Final Plans

The final documents for construction will contain plans, general conditions, special provisions,
specifications, and estimates necessary to construct the project in its entirety. A complete set of
stamped drawings in Adobe PDF format will be supplied to the City as well as Word and Excel
files of all the other construction documents, including general conditions, specifications, special
provisions, bid forms, and estimates. The City will be responsible for completing the LPA forms
required by NHDOT with information supplied by MJ. It is assumed that the printing of contract
documents will be completed by MJ and limited to two (2) full-size and five (5) half-scale plan
sets. Contractors will be expected to print their own plans from the supplied PDF files.

Phase 3D — Steering Committee Meetings

The Project Steering Committee will meet once during Final Design prior to project
advertisement. MJ will also present the project to the Board of Alderman Committee on
Infrastructure and the Board of Public Works prior to project advertisement.

MJ will continue to update the project website with meeting information and project documents
through the bidding services phase.

Phase 3E — Project Meetings

MJ will meet with City staff periodically during the Final Design Phase. It is assumed that two
(2) MJ staff will attend and facilitate these meetings. MJ will generate meeting notes that will be
distributed after each meeting. It is assumed two (2) meetings will be held during Final Design.

Phase 4 — Bid Services

Bidding phase services have been included to assist the City in advertising of the project. MJ
will perform the following Bid Phase support services:

1. MJ will provide the City with electronic versions of the plans and specifications to
make available to prospective contractors. Paper copies of the plans and
specifications will be sent to the City and two (2) plan rooms. No paper copies will
be made available to prospective contractors.

2. Attend the pre-bid meeting to assist the City with the presentation of the project to

the bidders and respond to questions posed by the prospective bidders. Conduct a

Scope of Work
Phase IA archaeological sensitivity assessment and Phase IB intensive archacological investigation
East Hollis & Bridge Street Intersection Improvement Project NHDOT 16314
Nashua, New Hampshire
September 1, 2021

Independent Archaeological Consulting, LLC (IAC) proposes to complete a Phase IA archaeological
sensitivity assessment for the Intersection Improvement Project of East Hollis and Bridge Streets in Nashua,
New Hampshire. Pre-Contact Native American archaeology specialist Jacob Tumelaire, MA, RPA, and
Post-Contact archaeologist Jessica Cofelice, MA, RPA will serve as co-Principal Investigators for the
project. The pair has more than 10 years of experience in northern New England contract archaeology and
they both meet and exceed the Secretary of Interior 36-CFR-61 standards for professional archaeologists.

The project area falls within the Nashua-Hudson zone of asbestos disposal, with at least known three
asbestos disposal sites (ADS) within the boundaries of the study area. Prior to fieldwork, IAC will
coordinate with NHDES about asbestos hazards and instruct staff about the health risks from asbestos
exposure and how to detect potentially hazardous materials in the field.

The background research will comprise the review of known archaeological site files via NHDHR’s online
database (EMMIT), soil types, terrain, and surficial geology. Desktop review will also include historic
NHDOT project plans, particularly for 1970 construction of the bridge over the Merrimack River (NHDOT
C-7721). Ms. Cofelice will compare the 1970 existing conditions plans to historical atlases and maps to
consider the location of Post-Contact archacological features. [AC will conduct a field inspection as the
final component of the Phase IA assessment; if portions of the project area are found to be sensitive,
archaeologists will flag the locations for Dig Safe. IAC will prepare a report summarizing the results of the
Phase JA review prior to conducting any Phase IB testing.

At this juncture, we estimate that the Phase IB intensive archaeological investigation will comprise the hand
excavation of at least 30 shovel test pits, each measuring 0.5 m by 0.5 m, with four larger 1-m-x-1-m test
units to penetrate anticipated alluvial deposits. Archaeologists will maintain a buffer of a minimum of 20
m (66 ft) from known ADS locations, and if they encounter asbestos in testholes, they will halt excavation
and backfill. The Phase IB field effort will continue over the course of four days, with the assistance of
four archaeological technicians. IAC will augment the hand excavation with two days of mechanical
trenching with a small backhoe or excavator, operated by Mr. Tumelaire.

All artifacts, fieldnotes, photos, and other documentation will be returned to the IAC laboratory in Dover
for processing and analysis. IAC will catalog any recovered cultural materials and register any new
archaeological sites. The deliverable for the entire Phase IA-IB effort will be a single report incorporating
the Phase IA background research and the results from the Phase IB subsurface testing.

The New Hampshire Division of Historical Resources (NHDHR) has recently released guidelines for
artifact curation with stringent rules about artifact preparation and curation standards. The proposal
therefore includes time to contact landowners, prepare and package artifacts, complete required forms, and
compile fieldnotes per the NHDHR guidelines. We’ve also included $350.00 for curation costs, the price
set by NHDHR to receive a single box of artifacts for permanent curation. We’ve estimated these costs
based on expected artifact yield.

If you have any questions about the proposal, please do not hesitate to contact Jacob Tumelaire at
jtumelaire@iac-llc.net or by phone at 603-430-2970.

RE: East Hollis & Bridge Streets Intersection Improvement Project, Nashua — UPDATE
Hello Christine:

This letter is to update our proposal from February 2020; there have been many iterations of
proposals.

As you'll remember, we completed the RPR in 2018 and there was an agency meeting which we
attended to review it and set the scope for this subsequent survey phase of the project. It includes
the completion of a Historic District Area Form for the larger area that surrounds the Project Area
as a change from our original estimate. Therefore, the number of Individual Survey forms was
reduced to only two based on the refinement of the design to avoid impact on properties. There is
an increase in the amount of photography required, because all photographs taken for the RPR will
need to be reshot as they were taken in 2018 are therefore out of date.

Respectfully submitted,

Lyfe Emerson Monroe
