AGREEMENT FOR PROFESSIONAL SERVICES
BETWEEN
VANASSE HANGEN BRUSTLIN, INC,
AND
THE CITY OF NASHUA, NEW HAMPSHIRE
DOWNTOWN RIVERFRONT PROJECT
December 30, 2021
The following expands services under the existing agreement between the City of Nashua and
Vanasse Hangen Brustlin, Inc. (VHB) for the Nashua Downtown Riverfront Project dated
12/12/2019. This agreement is subject to the terms and conditions of the original contract.
SCOPE OF SERVICES
This agreement includes the following scope of work.
ENVIRONMENTAL ANALYSIS AND PERMITTING
The project will require work below the top of bank of the Nashua River, which would trigger a
Prime Wetland review by the NH Department of Environmental Services (NHDES) Wetlands
Bureau under RSA 482-A. Additionally, any structure or fill below ordinary high water would
require authorization by the US Army Corps of Engineers under Section 404 of the Clean Water
Act. The Corps permit will, in turn, trigger the need to demonstrate compliance with Section 106
of the National Historic Preservation Act. We note that the Nashua River is subject to an urban
exemption from the NHDES Shoreland Program under RSA 483-B. To expedite design and
construction, it is likely that the project would be constructed in two to three phases:
e Project components that can be constructed entirely outside of the jurisdiction of the
NHDES, Army Corps, and NHDHR. These will likely include the Cotton Transfer Bridge
ADA ramp, the redevelopment of Bicentennial Park, redevelopment of the driveway
behind the Clocktower apartment building, portions of the multiuse path along the
south side of the Nashua River from Main Street to Temple Street, and possibly other
smaller components that do not impact the resource area.
e Boardwalks, the New Pedestrian Bridge across the Nashua River, and trail improvements
resulting in work below the top of bank requiring temporary and permanent impacts
(such as piers) in the bed and banks of the Nashua River.
