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
