There are many improvements going on at Piedmont Park. I was recently there with a friend, and had not been there in a couple of years.
The park is widely used by dog-walkers (There is Dog Park which is being expanded), pedestrians, cyclists, and roller bladers on the many paved paths/streets in the park.
There is an entire remodel of the public pool area (while maintaining the historic structures), and a recent grand playground for children complete with new, green restrooms. There are also a huge number of other improvements for 2009-2010 with something like a 53 Acre expansion.
The resources and improvements planned for Piedmont Park should continue to improve Midtown, Piedmont Park and Ansley Park property values.
