  6. 6. Why an EAP?PURPOSE: to provide a plan for anexpedited, effectiveresponse to prevent failure of the levee.
  7. 7. Why an EAP?
  8. 8. Plans help mitigate impacts wheneverything goes wrong. Why an EAP?
  9. 9. Why an EAP?• BECAUSE  USACE IT’S A  FEMA  Fort Bend VERY County GOOD • PLUS these guys say so! IDEA!
  10. 10. “Larger levee systems with multiple pumpingstations requiremore detailed plans than smaller systems.”Department of Homeland Security What does the plan look like?
  11. 11. Engineers – technical description of the projectWhat does the plan look like?
  12. 12. What does the plan look like? Attorneys – legally sufficient to meet regulations, gui dance and liability issues
  13. 13.  Emergency Management and Responders – sample messages for warning, inundation maps for evacuations and provide assistance with resourcesWhat does the plan look like?
  14. 14. What does the plan look like? LEVEE OPERATOR – specific information for the levee including: identifying problems, who to notify, steps to take to resolve or minimize problems
  15. 15. Guidelines• USACE • Other o PL 84-99 o Fort Bend County Office o Rehabilitation and of Emergency Inspection Program (RIP) Preparedness o Levee Owner’s Manual o TCEQ 30 TAC Chapter o Flood Fighting 299 (dams) Techniques on Levees o Department of • (Appendix D of Levee Homeland Security Owner’s Manual) (FEMA) o Flood Emergency Plans • Emergency • (for Corp Dams) Preparedness Guidelines for Levees A Guideline for Owners and Operators, January 2012
  16. 16.  Contents of an EAP • USACE and TCEQ guidelines MUST included: o Notification Flow Chart o Responsibilities/Authorities o Emergency Identification System/Situational Awareness o Emergency SOGs
  17. 17. • TCEQ model:  Legal and regulatory information upfront  Description of the project  Responsibilities  Situational Awareness  Preventive Actions  Supplies and Resources  Inundation Area  Implementation  (More legal/documentation)  Supplemental Information • (TABs or Annexes with additional/supportive material) Contents of an EAP
  18. 18.  Who has responsibility during an emergency?  What resources do you really have?  What resources will you need to acquire?  What are your vulnerabilities?  What are your upstream impacts?  What are your downstream impacts? Based on YOUR Levee
  19. 19. Legal and Regulatory• Legal description of project• Legal authority under which project is operated• Legal authority during emergency• Regulatory information• Limits of plan• Purpose of plan: • Plan for an expedited, effective response to prevent failure of embankment
  20. 20. • Levee Description: • Where located – exactly • Construction method used • Key Measurements • Elevation of crest, height, length, etc. • Description of other features • Pump Stations, Gate Structures, etc.  Project Description * Texas Division of Emergency Management
  21. 21. The Board• Subchapter E –local entity is “. . . responsible for disaster preparedness and coordination of response. The presiding officer of the governing body shall notify the division* of the manner in which the political subdivision is providing or securing an emergency management program . . . .” • Texas Disaster Act of 1975, V. T. C. A. Government Code, Title 4, Chapter 418 Responsibilities * Texas Division of Emergency Management
  22. 22. • WHAT IS AN EMERGENCY? • Abnormal Condition – • could be an emergency if ignored • Watch Condition – • an obvious problem which may not lead to failure but requires remedial actions • Possible Failure Condition – • progressively worsening problem despite actions taken • Imminent Failure Conditions – • despite all efforts, failure is likelySITUATIONAL AWARENESS
  23. 23.  Who to notify• at each stage of a problem Simple steps to take problem specific (sloughing not the same as a sand boil) List of equipment required for steps flagging material up to excavator SPECIFIC TO YOUR LEVEE No concrete = no concrete SOGs  PREVENTIVE ACTIONS
  24. 24.  Where does the water go?  How  Floodplain mapping  Breach Analysis  Overtopping  Piping Failure  Inundation Map  Share with Office of Emergency Management and Law Enforcement AgenciesINUNDATION AREAS
  25. 25. EAPs are “living and breathing” documents!• When do you review the document?• When do you review the Notification Flowchart?• With whom do you share the document (and updates)?• What training is required?• How and when are exercises conducted? Implement/Maintain Plan
  26. 26. • People!  BoardWhat resources do  Key Consultants you have?  Volunteers • Equipment  Yours  Your Operators  Lease/Purchase  Borrow/Share • Other  USACE
  27. 27. Other Resources Emergency Lighting Sand and sandbags Shovels Weather gear Floatation Vests Plastic Sheeting Rip rap (gravel/rock) Portable Pumps Plywood Steel Posts Fencing Material Barricades Orange Fencing Fork Lift Backhoe Dump Truck Excavator Crane Boat Gator/ATVs Emergency Communications Equipment Levee Patrol Members Operations Center Staging Area (cell phones, radios, pagers – backup batteries) Safety gear for all participants (vest, gloves, etc.) Meals for responders/staff/volunteers
  28. 28.  Are there seepsConsider your /sloughing?vulnerabilities  What areas of the levee are difficult to patrol/observe?  What intrusions have been made into your levee?  Is your equipment working properly?  Know capabilities of your personnel
  29. 29. • What happens to other Districts if you breach? Impacts - Upstream• What happens to you if the / Downstream District next to you breaches?• Which river indicator do you use?• What are your triggers to take specific actions?• When to prepare for the arrival of tropical storm/hurricane.
  30. 30. Notification Flowchart
  31. 31. Responsibilities/Authority
  32. 32. “Abnormal Conditions” What is an  Unusual but not necessarilyEmergency? dangerous Observed: Cracks in the embankment crest or on slopes Action: Walk area of crest and slope and check for additional cracking. Stake the cracks and document size and location. Notify: District Engineer for further inspection. When do you worry about cracking?
  33. 33. What is an “Watch Conditions”  Can become an emergency; seriousEmergency? enough for close surveillance Observed: Numerous cracks in crest that are enlarging. Action: Initiate 24-hour surveillance. Monitor and measure cracking to determine speed and extent of problem. Mobilize to fill cracks. Notify: District Engineer, Board, Local Emergency Management officials When do you worry about cracking?
  34. 34. “Possible Failure” What is an  Working on it but failure is possibleEmergency? Observed: Large cracks in the crest that are rapidly enlarging during high water event (or if levee is loaded) Action: Continue monitoring and remedial actions. Parallel cracks indicate a slide – see remedial action for slides. Notify: District Engineer, Board, State and Local Emergency Management officials When do you worry about cracking?
  35. 35. “Imminent Failure” What is an  We can only lessen the impacts – notEmergency? prevent failure Observed: Cracking that extends to pool elevation – during high water event. Action: Evacuation within leveed area. Continue remedial actions. Notify: EVERYONE When do you worry about cracking?
  36. 36. SPEAK THE SAME LANGUAGE! Observation City of Sugar Land Many guidelines USACENew cracking, minor Emergency Level 3 Abnormal Level 1Progressive ------------------------- Watch -----------Increasing, multiple Emergency Level 2 Possible Failure Level 2Large chunks, loss of integrity Emergency Level 1 Imminent Failure Level 3
  37. 37. Guidelines for Operating the Levee “Under Duress” Who to call /when to call When to turn on / turn off the pumps How to start the generator What to look for during levee surveillance What equipment to take during levee surveillance What to watch for if threatened with sabotage ALL MUST BE SPECIFIC TO YOUR LEVEE!!
  38. 38. • Project Name• River/Tributary• Location o (city/county; township/section; GPS)• Emergency Contact Information o Notification Flowchart• Map o Inundation – could include your leveed area o Additional inundation information is obtained through modeling What the County Needs
