1 City of Salinas Flood Response Preparations

2 Winter Preparations Goals for 2015/2016 Community Preparedness in the event of flooding Media cooperation on safety and preparedness, public information sharing Location of Sandbags for private use Implement proactive steps to reduce the likelihood of flooding: Salinas River Channel Clearing Enhance emergency response capability to flooding incidents City/County wide

3 Cooperating Agencies & Collaborative Efforts County of Monterey Water Resources County of Monterey Board of Supervisors County of Monterey Farm Bureau City of Salinas Police Department County of Monterey Ag.

7 History of Flooding in California 1. Dec Rained for 45 days, Sac/San Joaquin Valleys, Orange County were lakes. California went bankrupt. (Atmospheric River) 2. Dec Rained 15 inches in one day. Stockton, Sacramento flooded (LN) 3. March wettest days ever; 34 Counties declared disasters, 500 yr. flood (LN) 4. Jan No. California, 280 million in damages (EN) 5. Feb year flood for northern California (EN) 6. Jan Salinas River flooded 4 above the Flood level of Jan Wettest single day recorded, 230 million in damages, rained 30 over 12 days (EN)

8 Monterey County Flood Damages of 1995, 1997 and 1998 All received state and federal disaster declarations ,000 acres damaged- $45 million in building/ Ag losses Jan and March 2 major storms- 11,000 residents displaced, $230 million in building/infrastructure/ag losses (EN)- Flooding in Carr Lake, Gabilan, Santa Rita and Natividad Creeks. Salinas River to Blanco Road. Kern Street Mobile Home Park flooded for 11 days. Preparations SFD and SPD not currently prepared for flood emergency response. *Specialized training and equipment is needed*

9 What is El Nino? El Nino is a warming of the Pacific Ocean s surface temperature near the equator more then normal. This disrupts the wind direction and jet stream and can cause more rain and severe weather in California, the southwest and South America. Asia and Australia typically will have drought conditions at the same time. Since 1951, there have been five (5) Strong El Nino winters. During these, rainfall was increased by 140%. In 1997/98 ocean temperatures were 2.7 degrees higher; today, they are 3.78 degrees higher.

10 What is La Nina? La Niña is characterized by unusually cold ocean temperatures in the Equatorial Pacific. Can have the same weather effect as an El Nino.

12 1997/98 and 2015/16 El Nino Comparison

13 Winter 2015/2016 El Nino Predictions 1. As large as the El Nino (largest recorded to date) 95% prediction- Dec. to March greatest activity 2. Already responsible for 15 named Hurricanes/Storms in the Pacific (33% increase), flooding in So. Cal and the southwest 3. Typically So. Cal/Southwest receives the brunt of storm activity 4. Past 4 El Nino outcomes: 50% chance of significant rainfall and major storm damage for No. California

14 How Can Local Flooding be Problematic this Year? Salinas River Channel severely restricted by sediment build-up and undergrowth. Significant reason for possible flooding! 1997 Flood Flow: 94,000 CFS 2015 Capacity (Est.): 39,000 CFS A majority of the Salinas River/local creek levees are not constructed to flood standards and have not been maintained for 8 years 4 th year of Drought- significant runoff probability Covered crops increase runoff capability: Strawberries Environmental and Food standard changes for areas that Flood. Stricter regulations enacted after Leafy Green Act

15 What is Needed to Prepare Salinas Swift Water Rescue (SWR) Awareness training for all SFD Personnel Personal Protective Equipment (PPE) for SFD personnel and potential victims Three (3) Rescue Boats and related equipment Cargo Trailer for equipment storage and emergency response Command Training for all SFD Officer Staff Provide training to SPD Command Staff First Responder Awareness (FRA) Training for PW Alert Monterey and EBS Notification awareness Funding needed for preparedness = $100,000

16 Potential Salinas River/City of Salinas Flooding Predictions from NOAA Historic crest of the Salinas River occurred on March 12, 1995 at feet. In 1998, was recorded on February 8 th. Flood Impacts- Above 24 - Low areas along the Salinas River will have significant flooding. River Road moderate flooding with Speckles Blvd. beginning to flood. Above 30 - Entire lower Salinas Valley will have disastrous flooding. Entire City in danger of flooding. Most of Castroville will flood. All roads near the Salinas River will be impassable. 90,000 acres of Ag. Land could be impacted.

17 Timelines for Emergency Response Training and Equipment Implementation City Manager approved additional funding: 8/29 On-Line Training program for all SFD Personnel completed: 10/30 Hands on Boat and rescue training (SPD, SFD): 11/20 PW Staff water awareness training: 11/30 Storm drain cleaning and equipment checks: 12/1 EOC planning and coordination with County OES: 12/15 Alert Monterey/Web EOC Enhancements: 1/16

18 Increased Response Capabilities through Funding SWRA response coverage available 24/7 All personnel safely trained and equipped to the SWRA level Pro-active response capable instead of reactive Requires minimal investment for safe and effective response capabilities Enhance/involve public awareness and community safety * Boat Operations only in life threatening situations*

19 Pro-Active Response Cooperation by City Departments- SPD/SFD/PW Ensure all storm drain/pump systems operational, tree trimming, channel/culvert clearing-pw Post/Evacuate flood prone areas imminently threatened-spd Patrol local waterways for potential victims and evacuate before rains begin-spd/sfd Open shelters during severe storms-city/county Increase police and fire staffing during severe storms, known flooding events- SPD/SFD PSA s- Flood prevention tips, post/patrol dangerous areas (English and Spanish)- All, Media Sandbag, Sand and Heavy Equipment- Co. PW/PW

20 SPD Resources Capable of carrying up to 8 in 3 of moving water

21 Losses to Agricultural/Tourism/Infrastructure from Flooding Agricultural losses could exceed 1 billion Total loss of 230 million from 1997 could be exceeded Flooded roads, lost bridges would affect tourism on the Peninsula greatly Recovery could be longer do to the Leafy Green Act Flooding could be more wide spread due to the current status of the Salinas River

27 Citizen Preparedness & Safety Tips and Information Help us help you.. 1. Evacuate when directed to do so 2. 50% of drowning victims are rescuers/would be rescuers 3. Subscribe to Alert Monterey: Tips for Flood Safety, protecting your home or business and safety around moving water: Monterey County OES- NOAA Flood Safety- FEMA English/Spanish- Before a Flood Safety Tips-

28 Understanding how Dangerous Moving Water is!! 1. 6 of moving water can knock you down! 2. Cars can be swept away in 2 of moving water! 3. The pressure and velocity of water can strip clothing, make it impossible to grab and hold objects and accelerate hypothermia! 4. Water pressure against an object: 62.4 pounds/sq. inch x CFS = Entrapment 5. Keep out of areas posted as dangerous! Stay away from moving/flooding waters
