2 North Bay Wildfires of 2017 Tubbs Fire 36,807 Acres 22 Deaths 5,643 Structures Destroyed Nuns Fire 56,556 Acres 3 Deaths 1,355 Structures Destroyed 37 Fire 1,660 Acres 25 Structures Destroyed 2

3 Enhanced Flash Flooding Risk Debris Flows Advanced Early Warning Protection of life and property Need for Post Fire Flood Warning 3

4 Tubbs Fire Timeline Oct 8: Fire starts Oct 10: 0% containment 27,000 acres Oct 14: 50% containment 35,470 acres Oct 21: 94% containment 36,793 acres Oct 31: 100% containment 36,807 acres Perfect Storm Rainy Season Officially starts October 1 Usually first storms in November Unpredictable long term forecast Just last year 4

5 Project Timeline Completed in under 2 months JAN 17, 2018 FEB 28, 2018 Contract Quickly approving contract. Design Site placement, Radio Path Analysis, TDMA planning. Integration Working with Napa County. Leverage what is available. Installation Feb 26: In just 3 days - 22 Gauge Stations fully operational. Completion Fully functional ALERT2 flood warning network by Feb 28. 5

28 Things to Consider for Quick Deployment Permitting Focus on right of ways Limit permitting Start early FCC Leverage what s available Existing neighboring networks USGS, HADS, METAR, CDEC Path Analysis Information & Technology Don t forget about I.T. Consider firewalls, DNS Servers, Networking Sales & Contracting Start discussing early Allow extra time for contracting process Other telemetry trypes Installation Flag and paint all locations Call 811 Discuss installation plans Vendors Partial shipments Expedited delivery Give heads up of incoming orders 28

29 29 Partnerships The key to success

30 Scott Bores and his staff at OneRain were instrumental in helping the Sonoma County Water Agency plan and implement a fully functional ALERT2 flood warning network within 3 months of having Board authorization for the project. The need on the heels of the October fires was imminent, and the pace at which we had to act was daunting. OneRain definitely stepped up to the plate to help us navigate this rapid deployment of our gage network. Their expertise and professionalism were invaluable throughout the process.
