finding for project-level conformity. MJ will determine if the project’s parameters fall within
the acceptable range of this finding. In addition, MJ will perform a qualitative assessment of
the proposed alternatives and potential air quality impacts of the project. Experience with
similar projects with higher traffic volumes indicates it is unlikely this project would result in
violations of the National Ambient Air Quality Standards (NAAQS). Therefore, no
quantitative microscale analysis is proposed. Instead, a description in general terms of the
changes in traffic patterns and their likely effects on air quality will be provided. Other
similar projects will be cited to support the conclusions.

e Noise — MJ will determine if the preferred alternative is considered a Type | project that
requires a noise analysis. If required, this analysis would be completed in the next phase of
the project.

e Traffic and Transportation —The existing traffic and transportation network will be described,
including any bicycle or pedestrian facilities within the project corridor.

MJ will attend one NHDOT Natural Resource Agency Coordination Meeting and Cultural Resource
Agency Coordination Meeting during Phase | of the project to obtain feedback on potential
resource concerns. It is anticipated that two MJ staff members will attend each meeting, and that
MJ will provide meeting minutes.

Phase ID — Project Definition

MJ will develop a formal Purpose and Need statement for the project consistent with NEPA and
other federal guidelines. The statement will be developed through public involvement. At the
Public Listening Session described in Phase IG, the issues, problems, concerns and deficiencies
of the East Hollis Street and Bridge Street intersection will be discussed. The results of these
public discussions will be the basis for the Purpose and Need statement.

Phase IE — Alternatives Development

A base plan will be prepared during this task for the purpose of developing conceptual alternatives
for the project. The base plan will use already available color aerial photographs with key features
identified. Existing right of way, property boundaries, and zoning information will be incorporated
from existing information.

The first step will be to develop, with consultation with the City, three (3) potential concepts for
consideration to determine which should be carried forward for further development. These
concepts will be schematic in nature with no detailed geometry.

Traffic analyses will be performed for the concepts to determine how they perform. It is assumed
that the Nashua Regional Planning Commission (NRPC) has information available from their
regional model that can be used to develop future traffic volumes. MJ will communicate with the
NRPC to develop projections that can be used to evaluate each alternative. Highway Capacity
Manual (HCM), Synchro, and Sidra software will be used to perform the evaluations. SimTraffic
software will be utilized to present traffic simulations of each alternative. In addition, Sidra
Intersection software will be used to evaluate roundabout concepts. Evaluations to be conducted
for the following scenarios:

e Existing Conditions (2017)
e Opening Year (2019) for No Build and Concepts
e Design Year (2039) for No Build and Concepts

These concepts will be presented at the Alternatives Workshop described later in this scope.

Step two will carry the preferred concept forward for further development as the Project Alternative.
The Project Alternative will be developed to a 30% level that includes lane widths, shoulder widths,
curve radii, taper rates, pavement markings, slope limits, existing and proposed right of way
requirements, and will be shown on both the aerial drawings and survey plans. A cost estimate will
be prepared for the alternative.

Streetscape — The East Hollis Street and Bridge Street intersection is one of the “Gateways” into
downtown Nashua. Streetscape/Landscape concepts for this location will be developed by
landscape architects CRJA-IBI Group. They will attend the project public meetings to gain an
understanding of the vision the City has for the project area. During the Engineering Study phase
CRJA-IBI Group will develop up to three (3) gateway themes for consideration. It is assumed one
theme will emerge and will be carried into the final design.

Engineering Study Report - MJ will prepare an Engineering Study report to document the preferred
alternative. The report will include a description of the existing conditions, the purpose and need
for the project, design criteria, description of the alternatives developed, cost estimates,
environmental considerations, and a conclusion.

Phase IF — Abstracting

Field evidence of boundary and ROW, including bounds, fences and lines of possession will be
located. A boundary survey of each abutting property is not included. The boundaries of abutting
properties that may influence the calculation of the property required to construct the project will be

located.
Phase IG — Public Involvement

Public Involvement for the project will include several committees and types of public meetings to
ensure all interested parties have the opportunity to participate. A concise Public Involvement Plan
will be implemented and is described in detail below.

Project Steering Committee — A Project Steering Committee will be formed to provide a conduit for
project stakeholders. Potential Steering Committee members include elected officials, City staff,
business groups, private citizens, and others as determined by the City. It is assumed the
committee will meet four (4) times, including once prior to the Public Listening Session, twice prior
to the Alternatives Workshop, and once prior to the Public Informational Meeting. MJ will prepare
presentation materials for the meetings and produce meeting minutes. The Steering Committee
will remain active through final design, however it will meet less frequently. It is also anticipated
that project meetings with City staff will occur throughout the project on an as needed basis.

A series of public meetings with specific purposes and goals will be held to educate the public on
the project and get their opinions. The specific meetings are described in more detail below.

Scope of Work and Task Descriptions
October 18, 2017

Public Listening Session — The first series of public meetings will be Listening Sessions designed
to gain an understanding of the public’s views, opinions, desires, and goals. A brief project
overview will be presented. However, the majority of the meeting will be to gain public comment
and information. The information from this session will be used to prepare the Purpose and Need
statement. Separate listening sessions will be held with the Board of Public Works, Board of
Alderman Infrastructure Committee, and one with the general public...

Alternatives Workshop — This workshop will take place after conceptual alternatives have been
developed for the project. The alternatives will include proposed intersection, aesthetic, and
access features. The alternatives will be presented on aerial photograph base maps. The public
will be encouraged to evaluate and comment on each alternative developed. A comparison matrix
of pertinent project elements will be presented. The objective of the meeting will be to reach a
consensus on the preferred alternative and a vision for the East Hollis Street and Bridge Street

intersection area.

Public Informational Meeting — Once the comments and suggestions from the Alternatives
Workshop have been incorporated into the Preferred Alternative, a Public Information Meeting will
be held to provide the public an opportunity to make final comments or suggestions. Project
graphics will also be displayed for public viewing before and after the meeting.

Board of Alderman & Board of Public Works Presentation - The MJ Team will make presentations
to the Nashua Board of Alderman Infrastructure Committee and the Board of Public Works after
the Public Informational Meeting. The presentations will summarize the project activities to date
and present the preferred alternative for approval.

Property Owner/Citizen Meetings — The MJ Team will attend up to four (4) meetings in addition to
those listed above with property owners or other private citizens to discuss the project.

Project Website and Social Media - Social Media and a project website will be used to ensure
project information is made available to the public. In consultation with City staff, MJ will create
and maintain a project-specific website. The website will provide project information and updates
(including project plans, meeting minutes, points of contact, future planned meetings, and other
key project information). The website will provide links to a project-specific Facebook page and
other social media sites deemed appropriate. The project website will be developed by MJ and will
be linked to the City’s website. MJ will create the project Facebook page. MJ will be responsible
for maintaining the website and Facebook page.

Phase IH — Utility Coordination

MJ will review existing utility information gathered by other NHDOT and City projects in the project
area. MJ will provide a list of the other projects for review by the City. The City will provide MJ
with all information regarding City owned water and sewer facilities within the project limits.
Existing utility information will be depicted on the project base maps. The plans will be sent to
known utility companies for verification of the location of the utilities shown on the plans.
