Planetizen is an online resource for urban planners. The website includes news stories about urban planning topics, as well as trainings and job postings that are relevant to planners.
The site has two topic areas that might be of interest to people who are working on community or strategic planning in smaller legacy cities:
Small Cities: A collection of stories related to the unique issues of small and mid-sized cities.
Legacy Cities: Stories related to older-industrial cities – although stories related to larger cities like Detroit or Cleveland are common, there are quite a few about smaller cities like Akron or South Bend as well.
