From The Preservation Alliance:
Each year an Endangered Properties List is published to bring attention to significant historic resources threatened by demolition or neglect. These properties are nominated by YOU – the public, neighborhood advocates, preservation professionals, community organizations and Alliance members. The list aims to raise the public’s awareness of vulnerable properties and to influence lawmakers who help form, uphold and promote preservation ordinances and incentives throughout the Philadelphia region.
Submit your nomination to the Preservation Alliance and rally support for your favorite at-risk neighborhood treasure… You are also encouraged to print out copies of the flyer (below) to get the word out. Post it on the bulletin board in your office or favorite coffee shop, give it to the neighbor who always says “someone should do something about that great old building,” give it to someone you know who loves architecture and challenge them to submit a nomination. The deadline for submissions is October 1, 2008.
