VHB performs Phase I Environmental Site Assessments (ESAs) at each proposed Sprint PCS site to determine if the potential exists for release of oil/hazardous materials. Phase II ESAs are initiated on sites where there is significant concern that contamination is present. VHB also performs wetland inspections and flagging at proposed sites to identify and delineate wetlands and determine permitting requirements.

Additionally, VHB reviews environmental resource information for environmental consequences pursuant to Federal Communications Commission (FCC) requirements. Specifically, VHB determines if a proposed facility would be located in an environmentally sensitive area, including:

• Designated wilderness areas
• Designated wildlife preserves
• Threatened or Endangered Species or designated critical habitats
• National Register of Historic Places sites
• Native American religious sites
• Flood plains

VHB maps the database and site information using both GIS and CADD to create a graphic depiction of each proposed site to show any nearby sensitive areas. We also integrate existing databases such as environmental databases, land uses, existing FCC-regulated communications towers, water resources, and local zoning maps in order to facilitate evaluation and management of comprehensive program-wide information.
