Additional Flood Hazard Information

The City of Flagstaff Stormwater Section offers the following additional flood hazard information and services:
1. Flood Hazard Zone Determinations ‐ $30 unless within 100 feet of a flood zone, then free of charge. Contact Jim Janecek at

2. We keep a drainage complaint database. If you have a drainage problem, we will collect your information and investigate. Our investigations include site visits and discussions with you on what steps you can take to correct the problem. If you have a drainage problem, please contact Chris Palmer at 928‐213‐2474, or email him at

3. The City of Flagstaff operates a small network of radio-telemetered gauges that transmit rainfall and stream flow information in real-time (as it occurs). If you would like to see this information for the various locations in the City, plus the rain gauges in the Schultz burn area, go to: Rainfall and Stream Gauge Data. This network can send emergency alerts via text messaging and/or email for heavy rainfall. If you would like to receive these alerts, please send your request with your email address and/or cell phone number to Jim Janecek at
