Exhibit A
Nashua - Crown Street Park & Ride Project
Scope of Work and Task Descriptions
June 15, 2016
° Construction considerations including excavation, temporary support of excavation,
dewatering, and removal of unsuitable materials.
We will prepare a geotechnical engineering report that describes the work performed, our findings,
conclusions, and recommendations. Our report will include logs of the explorations, a plan
indicating the locations of the explorations, and design details that may be necessary to
supplement the text. An electronic PDF version of the report will be provided. Boring logs will also
be provided electronically in DXF format to be included in the design plan set for the project.
Soil and Groundwater Management Plan - GZA will prepare a draft Soil Management Plan to
govern activities that may involve the disturbance of urban fill and petroleum contaminated soils at
the Site in consideration of the proposed site development, including:
° Development of a Site-Specific Health and Safety Plan;
e Development of a pian to manage the identification, stockpiling, and disposal of urban fill
and petroleum-contaminated soils;
e Segregation of soils;
e Management of stockpiled soil, asphalt, debris, and/or concrete while awaiting waste
characterization or reuse on-Site;
e Criteria for reuse and disposal of soil and any obstructions identified (i.e., foundations,
demolition debris, etc.);
e Management of water collected by dewatering during construction; and
*« Operation and maintenance of cover materials (i.e., clean fill, bituminous pavement, or
concrete).
An electronic PDF version of the report will be provided.
Task 3 — Final Design
Task 3.1 - Environmental Permitting
The project will require an Alteration of Terrain permit because it proposes over 100,000 square
feet of disturbance. MJ will prepare an Alteration of Terrain Site Specific permit application and
related plans and drainage design information for submission to NHDES. The City will be
responsible for any application fees. The site is located within a % mile of a designated river, the
Lower Merrimack River. A copy of the AoT permit will be submitted to the Local Advisory
Committee (LAC) and a representative of MJ will attend a LAC meeting if requested to do so.
It is assumed no other environmental permits will be required for this project.
Task 3.2 — Preliminary Plans, Specifications and Estimates
The Preliminary Plans will be further developed based on comments received from the City and
NHDOT. In addition to the plans developed under Task 2, the following drawings will be created.
All plans will be completed to a 95% complete level.
