Description
Geographical Information Systems (GIS)
Tools (including the computer programs) used to gather, transform, manipulate, analyze and produce information related to the surface of the Earth. This information or data may be represented by maps, three dimensional models, tables and/or lists.
Green Sheets
A green-colored sheet with a list of special project commitments developed during the NEPA process is included in each final environmental document (CE, FONSI, DEIS). Additional commitments that are identified during the subsequent project development and permitting, including permit conditions, are included in the green sheet, which is incorporated into the construction contract as necessary.
Groundwater
Water that is found underground in the cracks and spaces in soil, sand and rock.
