Scope of Work for Engineering Services
4. Assessment of Street and Parking Lot Guidelines
The Permit requires the development of a report assessing current street design and parking lot guidelines and
other local requirements with respect to the creation of impervious cover. The assessment must evaluate the
potential for the modification of design standards for streets and parking lots to support low impact design
options. Should such changes be feasible, the assessment shall include recommendations and proposed
schedules for such revisions that would result in reduced impervious cover attributable to parking areas and
street designs.
Hazen’s duties include:
Task 4.a Conduct site visits of city-owned properties and inventory those with green infrastructure or low
impact development (LID) practices.
Task 4.b Review Nashua’s existing street and parking lot design guidelines and requirements. Identify
example design guidelines that facilitate low impact design and compare with Nashua’s.
Task 4.c Conduct a workshop with the City of Nashua to review the preliminary findings and
recommendations.
Task 4.d Prepare a report detailing the findings and recommendations along with a schedule for
implementation.
Deliverable: Street and Parking Lot Guidelines Assessment Report
