e Address state and federal erosion and sedimentation control permitting requirements in
the project design,
e Prepare a drainage report that summarizes any changes in existing flows or drainage
patterns,
e Prepare a draft application for permit under the AoT program,
¢ Sign and stamp final civil design documents by a Professional Engineer (PE) licensed by
the State of New Hampshire, and
e¢ Complete a wildlife habitat assessment by a certified wildlife biologist pursuant to Env-
Wq 1503.19(h).
Based on the urban nature of the project, VHB assumes that NHDES will waive the requirement
for Site Specific Soiis Mapping (SSSM). VHB will coordinate with the City and NHDES regarding
an informal consultation on the draft permit application and plans and to confirm our
assumption regarding the applicability of receiving a waiver from the SSSM requirement.
Pursuant to comments from the City, VHB will revise plans and application materials and would

submit the permit application to NHDES.

Task 8. NHDHR Request for Project Review

Because the project will require coverage under a federal Section 404 permit, compliance with
Section 106 of the National Historic Preservation Act (Section 106) will be required. VHB will
therefore prepare up to two Requests for Project Review (RPR} to initiate coordination with the
NH Division of Historical Resources (NHDHR). As part of this task, at NHDHR’s suggestion, VHB
will overlay historic Sanborn maps onto the project area as a form of preliminary archaeological
assessment. This task will include one visit to the project site to complete photography, NHDHR
site file review, completion of a draft and final version of the RPR, and attendance at one
coordination meeting between NHDHR and the client (virtually or in person).

Task 9. Cultural Resources Surveys - Individual Inventory Forms

Although the historic resources surrounding the project area has been heavily documented, two
properties were identified during preliminary consultation with NHDHR that will require NHDHR
Inventory forms be prepared to determine their National Register eligibility and assess potential
project impacts. VHB will prepare NHDHR individual inventory forms per the NHDHR survey
manual for 4 Water Street and 58-60 Main Street, Nashua.

Tasks required to complete the inventory forms includes a site visit to photograph each
property, record site observations, and to identify and photograph properties for contextual
comparison. Research will be conducted at local repositories including the Nashua Historical
Society and Nashua Public Library, as well as state repositories including the New Hampshire
State Library and the New Hampshire Historical Society in Concord.
