Honorable Mayor James Donchess
City of Nashua

Main Street

Nashua, NH 03060

Dear Mayor Donchess,

We are writing to you as co-chairs of the One Greater Nashua Coalition. Our coalition includes over 120 greater Nashua
residents with 40 active volunteers and more than a dozen anchor organizations that share your value for our city’s
growing diversity. Members of our coalition represent residents from all walks of life including long-term residents,
business owners and established community leaders. With funding from the Endowment for Health and NH Charitable
Foundation, we have formed a three-year plan to increase social inclusion and integration for all people in our
community that feel isolated and disconnected including new comers. Through this work we expect to increase
Nashua’s economic vitality and improve long term health outcomes for our community.

One Greater Nashua was formed about 1% years ago. At the end of our first year, we were proud to report that our
efforts resulted in mobilizing over 40 active volunteers that contributed over 5,676 hours to our city. *

As you well know, our current demographic trends compel us as a community to ensure that all students in our school
district achieve their highest potential. As baby boomers retire, we will be challenged to find millennials to take their
place. Data demonstrates New Hampshire among the states with the oldest and least diverse population. This is not a
sustainable trend. While we are among the states most challenged by an aging population, it is clearly a national
problem. Economist Ken Johnson of UNH’s recent research highlights that there have not been enough millennials born
in the US to replace the retiring baby boomers. Furthermore, millennial lifestyle choices indicate a preference for
multicultural communities with a diverse and welcoming attitude. | believe you heard this message clearly stated from
NH millennials at the state welcoming week conference in Manchester last week. We will have to work hard as a city to
maintain a strong enough workforce to retain the businesses we already have as well as stimulate growth. Every person
that lives in our community is an asset we cannot afford to overlook.

Our volunteers are working with the ELL middle and high schoo! students to empower and inspire our students from
diverse cultural backgrounds to feel and understand that our community values their potential and is willing to help
them break down any social barriers that may hold them back. The Nashua School District Ell Department and the Boys
and Girls Club are helping to anchor this work. Social barriers to health are clearly named in the Community Needs
Assessment and people of color are disproportionately affected. Feeling welcome and included in the community is an
important factor that can impact long term health outcomes as well as academic success and future economic mobility.

required by subparagraph 5.04.B.7; (ii) consent of the surety, if any, to final payment; and (iii) complete and legally
effective releases or waivers (satisfactory to OWNER) of all Lien rights arising out of or Liens filed in connection
with the Work.

3. In lieu of the releases or waivers of Liens specified in paragraph 14.07.A.2 and as approved by OWNER,
CONTRACTOR may furnish receipts or releases in full and an affidavit of CONTRACTOR that: (i) the releases and
receipts include all labor, services, material, and equipment for which a Lien could be filed; and (ii) all payrolls,
material and equipment bills, and other indebtedness connected with the Work for which OWNER or OWNER's
property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or Supplier
fails to furnish such a release or receipt in full, CONTRACTOR may furnish a Bond or other collateral satisfactory to
OWNER to indemnify OWNER against any lien.

B. Review of Application and Acceptance

1. If, on the basis of ENGINEER's observation of the Work during construction and final inspection, and ENGINEER's
review of the final Application of Payment and accompanying documentation as required by the Contract
Documents, ENGINEER is satisfied that the Work has been completed and CONTRACTOR's other obligations under
the Contract Documents have been fulfilled, ENGINEER will, within ten days after receipt of the final Application
for Payment, indicate in writing ENGINEER's recommendation of payment and present the Application for Payment
to OWNER for payment. At the same time ENGINEER will also give written notice to OWNER and CONTRACTOR
that the Work is acceptable subject to the provisions of paragraph 14.09. Otherwise, ENGINEER will return the
Application for Payment to CONTRACTOR, indicating in writing the reasons for refusing to recommend final
payment, in which case CONTRACTOR shall make the necessary corrections and resubmit the Application for
Payment.

C. Payment Becomes Due

1. Thirty days after the presentation to OWNER of the Application for Payment and accompanying documentation,
the amount recommended by ENGINEER will become due and, when due, will be paid by OWNER to
CONTRACTOR.

14.08 Final Completion Delayed

A. If, through no fault of CONTRACTOR, final completion of the Work is significantly delayed, and if ENGINEER so
confirms, OWNER shall, upon receipt of CONTRACTOR's final Application for Payment and recommendation of
ENGINEER, and without terminating the Agreement, make payment of the balance due for that portion of the Work
fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or
corrected is less than the retainage stipulated in the Agreement, and if Bonds have been furnished as required in
paragraph 5.01, the written consent of the surety to the payment of the balance due for that portion of the Work fully
completed and accepted shall be submitted by CONTRACTOR to ENGINEER with the Application for such payment.
Such payment shall be made under the terms and conditions governing final payment, except that it shall not
constitute a waiver of Claims.

14.09 Waiver of Claims
A. The making and acceptance of final payment will constitute:

1. A waiver of all Claims by CONTRACTOR against OWNER other than those previously made in writing which are
still unsettled.
