Exhibit A
Scope of Work: City-Wide Pedestrian Infrastructure Conditions Assessment and Ranking
SYNOPSIS:
The City of Nashua, NH (the City) is committed to creating accessible paths of travel in the public right-
of-way for people of all abilities. In order to enhance compliance with the Americans with Disabilities
Act (ADA), the City desires to complete a city-wide inventory of pedestrian infrastructure. Once
complete, this inventory will assist the City in identifying priority locations for improvements and
maintenance and will become the primary input to a comprehensive ADA plan.
EXISTING RESOURCES:
The City and The Nashua Regional Planning Commission (NRPC) have a solid base of resources and
expertise to ensure the success of this project. Specifically,
¢ The New Hampshire Department of Transportation (NHDOT) has developed a cloud GIS mobile
data collection framework known as the Statewide Asset Data Exchange System, or SADES, and
made this framework available to the nine RPCs in the state. Built on the ESRI ArcGIS for Server,
ArcGIS Online, and ESRI Collector stack, the SADES system establishes a primary inventory and
maintainable condition assessment process for transportation assets in the state. SADES has
been specifically tailored to capture pedestrian infrastructure data for ADA compliance.
e NRPC is well-versed in SADES. NRPC partnered with the City of Nashua in 2020 to conduct a
city-wide pedestrian Level of Service Analysis that included 17 miles of SADES pedestrian
infrastructure assessment. Additionally, in 2017 NRPC inventoried seven miles of sidewalk, 18
crosswalks, and 103 curb ramps along Daniel Webster Hwy in Merrimack, NH.
e The City has a robust geographic information system (GIS) that includes new city-wide location
data on sidewalks and crosswalks. These features will serve as an important input into the
SADES GIS data model and will be further developed through the course of the project. Any
missing or misclassified sidewalks and crosswalk features will be corrected, all necessary
attributes will be added, and an inventory of curb ramps and pedestrian signals will be created.
PROJECT PHASES
Phase 1: Field Data Collection
In partnership with the City, the Nashua Regional Planning Commission (NRPC) will complete a
comprehensive city-wide program of field data capture for sidewalks, crosswalks, curb ramps, and
pedestrian signals. This infrastructure will be compiled into a spatial database that includes the
presence or absence of features, their relative condition, and associated physical barriers. This work
expands upon the 17 linear miles of sidewalk already surveyed by NRPC during summer of 2020. This
project will primarily consist of an extensive field data collection campaign using state-of-the-art mobile
and cloud-based GIS.
