e Discussion of potential impacts related to each alternative (historical,
environmental, utilities, existing structures, Right-of-Way, etc.),
® Conceptual cost estimate, and
® Conceptual level plans for alternatives (typical section, general roll plan).
The Alternatives Analysis process will be used to recommend the most viable and
preferred alternative to advance to Preliminary Design phase. Once a proposed action is
selected by the City, the project can proceed to documenting the process for inclusion in
the final Engineering Study report.
1.12 Conceptual Engineer's Opinion of Probabie Cast (EOPC)
CMA Engineers will provide an itemized EOPC for each of the alternatives considered
using NHDOT item numbers, descriptions, materials, and construction requirements that
are contained in the NHDOT Standard Specifications {i.e., Division 200 through Division
700). The itemized EOPC will include contingencies and separate line items for
construction services in accordance with the LPA Manual.
1.13 Public Presertaiion of Fropesed Action
CMA Engineers, in collaboration with the City, will conduct a second public meeting that
will focus on the Proposed Action as approved by the Sponsor with an update on the
schedule, budget and potential neighborhood impacts. This meeting will likely be held in
conjunction with a Board of Mayor and Alderman Meeting. Minutes of the meeting will
be incorporated into the Engineering Study document. This task will also include a
meeting with the City and an additional brief meeting with NHDOT prior to the Public
Proposed Action Meeting to ensure all parties are in agreement with the proposed action
before presenting to the public.
1.14 Engineering Siudy Submission
An Engineering Study report will be developed that incorporates the following
information:
a. Purpose and need statement, including alternatives identified, evaluated, and
approved by the City.
b. Information to demonstrate that the proposed corrective effort is justified,
worth the expenditure of funds, and incorporates mitigation for impacts to
affected natural and cultural resources.
c. Summary of the existing conditions, descriptions of the existing project
location, length and width of the proposed project, type of facility, and
apparent or unique features.
d. Summary of the relevant design criteria and manuals to be utilized for the
project,
e. Existing drainage systems and how the proposed work will interact with the
existing drainage system.
f. Incorporate the environmental/historical documentation developed for the
project with associated issues.
g. Discuss the location of the ROW relative to the project footprint and identify
likely easements or takings as needed,
