Preliminary Issues
• A historic preservation easement should be considered for the Whitefield Commons area,
designated as an “Important Resource” in the County’s HRI
• Additional surface parking area at the expense of existing tree canopy coverage
• Potential need to improve existing sidewalks along the Whitefield Commons site area
• Blank facade area and insufficient screening of structured parking along the service drive
and at N. Trenton Street
• Details needed for proposed open space:
– Playground area use and conceptual design
– Public easement
• Concern over second row of townhouses fronting the back of surface parking area
• A 36-inch storm sewer pipe is located beneath two existing Whitefield Commons buildings
