Four times a year, APA's Planning Advisory Service publishes a new PAS Report with guidance on current issues and innovative practices.

APA members and PAS subscribers can download each new report as it is posted, and can download nearly 100 reports published since 1994. PAS subscribers also receive a print copy of each new PAS report.

Latest Report


The latest PAS Report identifies emerging trends in regional planning; explores how regions are planning for water and land resources, economic development, housing, climate change, and public health; and highlights five U.S. regions leading the way in regional integrated planning.

Historic Reports
