Original Case Study Title: Marana, Arizona-Keeping Hazardous Areas Open

Original Document: “NAI How-to Guide for Regulations and Development Standards” ASFPM, 2017. Pages: 86-91.

Summary: The town of Marana AZ decided to update their local ordinances. The town wanted to address two problems: the mapping standards did not include smaller watersheds and the mapping and regulatory standards did not address erosion and scour. The new 2008 code that was developed addresses those issues in order to produce No Adverse Impact results.
