1 State of the Siren Warning System

2 Why are we here Siren funding questions Siren funding questions Maintenance of current system Maintenance of current system How do we pay for it, Who pays for it How do we pay for it, Who pays for it Opportunity for replacement sirens Opportunity for replacement sirens $100,000 county wide for 30 sirens plus the control system – Do we want it? $100,000 county wide for 30 sirens plus the control system – Do we want it?

3 Questions for the Workshop What part do Sirens play in the county warning system? What part do Sirens play in the county warning system? How much should the County and Cities invest in the sirens? How much should the County and Cities invest in the sirens? How do we pay for the sirens? How do we pay for the sirens? How do we coordinate the maintenance and repairs to assure operation? How do we coordinate the maintenance and repairs to assure operation?

4 Where do Sirens fit into public warning systems Reverse 911 Reverse 911 Delivers a custom message to land lines based on geographic area Delivers a custom message to land lines based on geographic area Can cover the entire county in about 2 hours Can cover the entire county in about 2 hours Does not work geographically with Cell Phones Does not work geographically with Cell Phones Needs Internet plus Phone systems Needs Internet plus Phone systems NoAA Weather Radio NoAA Weather Radio Available all over, reliable Available all over, reliable Needs Phone system Needs Phone system EAS (Emergency Broadcast system) EAS (Emergency Broadcast system) Good for getting message to anybody with a radio or tv turned on.

9 Examples of current status

10 Systems in place Systems in place Siren Operations Call to 911 for activation Call to 911 for activation From Local Emergency Manager From Local Emergency Manager From NoAA via State Warning point From NoAA via State Warning point 911 operator Presses the button 911 operator Presses the button Primary System if available, Secondary if not Primary System if available, Secondary if not Sheriff has tertiary activation capabilities Sheriff has tertiary activation capabilities County radio relays command to all sirens County radio relays command to all sirens Sirens sound 3 minute signal automatically Sirens sound 3 minute signal automatically

11 Systems in place Systems in place Siren Maintenance Owners are responsible for: Owners are responsible for: Electrical costs Electrical costs Repairs/Replacement Repairs/Replacement Reporting on test day Reporting on test day County program is responsible for: County program is responsible for: Twice yearly performance testing Twice yearly performance testing County maintains relay radio for activation County maintains relay radio for activation County maintains tertiary activation system County maintains tertiary activation system County coordinates test reporting County coordinates test reporting 911 maintains 911 maintains Primary and secondary activation system Primary and secondary activation system Communications link to State OEM for notification Communications link to State OEM for notification No agreements exist No agreements exist

12 Expected performance of the warning systems Near shore earthquake and Tsunami Likely failure of power, telephone, Internet and transportation systems Likely failure of power, telephone, Internet and transportation systems Possible failure of 911/county radio system Possible failure of 911/county radio system 20 minutes for notification via NAWAS, NWS, EAS systems (if they work) 20 minutes for notification via NAWAS, NWS, EAS systems (if they work)

13 Expected performance of the warning systems (contd) Distant earthquake Distant earthquake No shaking felt locally No shaking felt locally No infrastructure damage, all systems work No infrastructure damage, all systems work Tsunami Watch issued (20 minutes) Tsunami Watch issued (20 minutes) Tsunami Warning issued when wave is verified Tsunami Warning issued when wave is verified Will receive wide Radio/TV coverage Will receive wide Radio/TV coverage Wave arrival times and heights predicted Wave arrival times and heights predicted

14 Weaknesses of the current siren system Funding – Funding – Not all the owners have or are willing to spend the money for maintenance Not all the owners have or are willing to spend the money for maintenance Funds compete with other needs like Police, Fire trucks, and Parks Funds compete with other needs like Police, Fire trucks, and Parks Age/Maintenance Age/Maintenance Constant maintenance needs Constant maintenance needs Rust, Age, Updates Rust, Age, Updates Replacement planning Replacement planning

15 maintenance costs Electric$200 to 300/year/Siren Electric$200 to 300/year/Siren Visual Inspection $ 20 /year/Siren Visual Inspection $ 20 /year/Siren Electronic Tests$ 40 /year/Siren Electronic Tests$ 40 /year/Siren Operational Tests$ 240/year Operational Tests$ 240/year Test reporting$1200/year Test reporting$1200/year Repairs Repairs Replace hood$1200 Replace hood$1200 R&R radio with spare$ 85 R&R radio with spare$ 85 Repair/Replace Cutoff switch$1200 Repair/Replace Cutoff switch$1200 Replace motor Head$3000 Replace motor Head$3000 Replace Relay$1200 Replace Relay$1200 Replace Radio with New$2700 Replace Radio with New$2700

16 County spending year$ 6, year$ 6, year$38, year$38, year$ 3, year$ 3, year$ 3, year$ 3, year$ 15,000* year$ 15,000* Estimated maintenance is $1000/siren/year Estimated maintenance is $1000/siren/year * Projected budget amount

17 Other Impacts NWS – Tsunami Ready NWS – Tsunami Ready Sirens are one of the accepted means of warning dissemination. Sirens are one of the accepted means of warning dissemination. Need two methods of dissemination– Sirens are ONE of our systems. Need two methods of dissemination– Sirens are ONE of our systems. Flood Insurance Rating System – Flood Insurance Rating System – Tsunami damage is considered Flood damage and falls under the NFIP Tsunami damage is considered Flood damage and falls under the NFIP FEMA provides better rates for Tsunami Ready Communities, 30 points. FEMA provides better rates for Tsunami Ready Communities, 30 points.

18 Options for the Siren System 1.Eliminate the siren warning and activation system completely. Build public education campaign instead. 2.County/911 maintain only the activation system, local agencies must support and pay for the sirens. No standards, County/911 only provide the activation signal. 3.Establish a Fund for siren maintenance and care. Each jurisdiction/district pays a fixed amount per siren per year into the fund, or they are pulled out. The fund takes care of all the sirens. Agreements will be established. Only sirens within the fund are allowed for Tsunami use. 4.Maintain Current status – Private ownership of sirens. Sirens may be pulled out when private parties or jurisdictions cannot raise funds for maintenance; County/911 maintain activation system; County maintains twice yearly certification testing program. 5.Improve and expand the system for more coverage and better sirens – Funding unknown.

How much should the County and Cities invest in the sirens? How do we pay for the sirens? How do we pay for the sirens? How do we coordinate the maintenance and repairs to assure operation? How do we coordinate the maintenance and repairs to assure operation?
