Evacuation planning and actual implementation has to be based upon certain assumptions. It must be understood that the need to evacuate elements of the population can occur at any time, events resulting in evacuations occur with various amounts of lead time and every evacuation will be unique and offer unexpected challenges to those conducting the evacuation. Evacuations in response to hazardous material spills or sudden severe weather are provided with little or no warning, and often have to be accomplished after the fact, and in a disaster response environment.
Throughout the Parish persons with special needs, require special consideration regarding notification, transportation, and sheltering. Resources of equipment, facilities and personnel are more difficult to locate and coordinate when an evacuation is required during late night or early morning hours. If possible, advance warning should be given so an evacuation can be coordinated. Adequate provisions should be maintained at all times in order to conduct a warning or alert of an area.
Certain hazards, such as a hurricane, provide some lead time for coordinating an evacuation. However, this can not be considered a certainty. Plus, the sheer size of an evacuation in response to an approaching hurricane creates the need for the use of community-wide warning resources, which cannot be limited to our City's geographical boundaries.
Evacuation of major portions of our population, either in response to localized or citywide disasters, can only be accomplished if the citizens and visitors are kept informed of approaching threats on a timely schedule, and if they are notified of the need to evacuate in a timely and organized manner. If an evacuation order is issued without the mechanisms needed to disseminate the information to the affected persons, then we face the possibility of having large numbers of people either stranded and left to the mercy of a storm, or left in an area impacted by toxic materials…
General evacuations that may result from an approaching hurricane will be ordered by the Mayor of the City, upon the recommendation of the Director of the Office of Emergency Preparedness. The area affected by the warning may range from blocks and portions of neighborhoods, to the entire city…
The safe evacuation of threatened populations when endangered by a major catastrophic event is one of the principle reasons for developing a Comprehensive Emergency Management Plan.
The thorough identification of at-risk populations, transportation and sheltering resources, evacuation routes and potential bottlenecks and choke points, and the establishment of the management team that will coordinate not only the evacuation but which will monitor and direct the sheltering and return of affected populations, are the primary tasks of evacuation planning. Due to the geography of New Orleans and the varying scales of potential disasters and their resulting emergency evacuations, different plans are in place for small-scale evacuations and for citywide relocations of whole populations.
Authority to issue evacuations of elements of the population is vested in the Mayor.
By Executive Order, the chief elected official, the Mayor of the City of New Orleans, has the authority to order the evacuation of residents threatened by an approaching hurricane.
Evacuation procedures for special needs persons with either physical or mental handicaps, including registration of disabled persons, is covered in the SOP for Evacuation of Special Needs Persons.
Major population relocations resulting from an approaching hurricane or similar anticipated disaster, caused the City of New Orleans Office of Emergency Preparedness to develop a specific Hurricane Emergency Evacuation Standard Operating Procedures, which are appended to the Comprehensive Emergency Management Plan.
The SOP is developed to provide for an orderly and coordinated evacuation intended to minimize the hazardous effects of flooding, wind, and rain on the residents and visitors in New Orleans. The SOP provides for the evacuation of the public from danger areas and the designations of shelters for evacuees…
The Hurricane Emergency Evacuation Standard Operating Procedure is designed to deal with all case scenarios of an evacuation in response to the approach of a major hurricane towards New Orleans.
It is designed to deal with the anticipation of a direct hit from a major hurricane. This includes identifying the city's present population, its projected population, identification of at-risk populations (those living outside levee protection or in storm-surge areas, floodplains, mobile homes, etc.), in order to understand the evacuation requirements. It includes identifying the transportation network, especially the carrying-capacity of proposed evacuation routes and existing or potential traffic bottlenecks or blockages, caused either by traffic congestion or natural occurrences such as rising waters. Identification of sheltering resources and the establishment of shelters and the training of shelter staff is important, as is the provision for food and other necessities to the sheltered. This preparation function is the responsibility of the Office of Emergency Preparedness.
Conduct of an actual evacuation will be the responsibility of the Mayor of New Orleans in coordination with the Director of the Office of Emergency Preparedness, and the OEP Shelter Coordinator…
The City of New Orleans will utilize all available resources to quickly and safely evacuate threatened areas. Those evacuated will be directed to temporary sheltering and feeding facilities as needed. When specific routes of progress are required, evacuees will be directed to those routes.
Special arrangements will be made to evacuate persons unable to transport themselves or who require specific life saving assistance. Additional personnel will be recruited to assist in evacuation procedures as needed…
As established by the City of New Orleans Charter, the government has jurisdiction and responsibility in disaster response. City government shall coordinate its efforts through the Office of Emergency Preparedness..
The authority to order the evacuation of residents threatened by an approaching hurricane is conferred to the Governor by Louisiana Statute. The Governor is granted the power to direct and compel the evacuation of all or part of the population from a stricken or threatened area within the State, if he deems this action necessary for the preservation of life or other disaster mitigation, response or recovery. The same power to order an evacuation conferred upon the Governor is also delegated to each political subdivision of the State by Executive Order. This authority empowers the chief elected official of New Orleans, the Mayor of New Orleans, to order the evacuation of the parish residents threatened by an approaching hurricane…
Using information developed as part of the Southeast Louisiana Hurricane Task Force and other research, the City of New Orleans has established a
maximum acceptable hurricane evacuation time standard for a Category 3 storm event of 72 hours. This is based on clearance time or is the time required to clear all vehicles evacuating in response to a hurricane situation from area roadways. Clearance time begins when the first evacuating vehicle enters the road network and ends when the last evacuating vehicle reaches its destination.
Clearance time also includes the time required by evacuees to secure their homes and prepare to leave (mobilization time); the time spent by evacuees traveling along the road network (travel time); and the time spent by evacuees waiting along the road network due to traffic congestion (delay time). Clearance time does not refer to the time a single vehicle spends traveling on the road network. Evacuation notices or orders will be issued during three stages prior to gale force winds making landfall.
> Precautionary Evacuation Notice: 72 hours or less
> Special Needs Evacuation Order: 8-12 hours after Precautionary Evacuation Notice issued
> General Evacuation Notice: 48 hours or less…
