Hurricane Katrina Aftermath New Orleans Devastation– September, 2005

Areas of Major Devastation : 

Areas of Major Devastation Lower 9th Ward – Orleans Parish Chalmette – St. Bernard Parish

Areas Not Re-populated : 

Areas Not Re-populated Orleans Parish Plans for rebuilding are unclear Latest recommendation by FEMA requires the elevation of residential dwellings raised 3 to 8 feet

Damage Assessment – New Orleans: 

Damage Assessment – New Orleans Assessment of Network Central Offices Destroyed Lake Catherine Pt-A-La-Hache Delacroix Yscloskey St Bernard

Damage Assessment – New Orleans: 

Damage Assessment – New Orleans Outside Plant Network Damages 1.9 Million Sheath Ft Underground Feeder Cables damaged beyond repair due to flooding affecting approximately 140,000 access lines in the following wire centers: Mid City, Lake, Seabrook, Franklin, Chalmette, Broadmoor and Carrollton Aerial spans down >2250 Spans Poles down >1,600 Interfaces or Cross Connect Boxes damaged > 700 Pedestals / Terminals damaged - 33,000 Remote Terminals/Multiplexer sites destroyed – 34

Oversight Restoration Strategy: 

Oversight Restoration Strategy Restore service to priority government agencies; hospitals, FEMA, Emergency personnel, Fire, Police etc. Reestablish service to all wireless providers. Rebuild feeder route backbone in all devastated wire centers, driven by repopulation, city planning and customer reports. Deploy SLC on Wheels (SOW’s) and other temporary solutions where the underground facilities were destroyed and restoration triggers are activated. Place sub-feeders and fiber extensions serving Digital Loop Carrier permanent solutions as repopulation continues. Rebuild or replace the cross-box/interfaces and distribution facilities in neighborhoods that are repopulating. Seek alternative technologies to bridge the gap in areas not yet restored.

The Challenge of Uncertainty: 

The Challenge of Uncertainty Katrina unlike most storms in the past kept population from returning for long periods of time and devastated entire neighborhoods. Repopulation was uncertain in some areas due to massive damages. Building codes and guidelines not established Customers did not always report outages Redevelopment was drastically different in adjacent areas based on flooding…Nothing was standard

Accomplishments – New Orleans: 

Accomplishments – New Orleans Engineered 4,842 Prints - Construction Completed 4,278 1.2 Million Feet Fiber Designed and placed 1.1 Million Feet Copper cable Designed and placed 1.5 Million Ft of Damaged Underground Cables removed 2.1 Million Ft of Fiber Innerduct placed 3500 Poles and Anchors placed 148 Electronics Sites placed; 60 additional in-progress 41 SOWS Engineered/Placed - Served >5000 customers 208 X-boxes Replaced 3153 Manholes Decontaminated – 413 tons of sludge removed Established Wireless Broadband Service in the greater New Orleans area in November Establish Fixed Wireless Voice Services to reach areas not connected by landline facilities

Damage Assessment by Area

Process & Network Enhancements: 

Process & Network Enhancements Established remote engineering processes and partners in other BellSouth states to design and engineer jobs. These designers receive field notes from local field forces and process jobs electronically back to local engineering forces. This will mitigate need for additional personnel and housing during housing shortages immediately following storms. Established new mapping tools to track progress. Brought in teams of Building Industry Consultants (BICS) experts to negotiate equipment room relocation and elevation in damaged buildings. 797 terminals were inspected. As of 8/1 still 77 buildings without access.

Process & Network Enhancements: 

Process & Network Enhancements Brought in outside right-of-way acquisition teams to supplement local teams. Teams negotiate easements for new elevated electronics sites. Where local permitting and easements allow sites are elevated above Katrina flood levels. Established fiber-fed facilities in the damaged feeder routes in heavily damaged wire centers. Established fiber-fed facilities to cell sites across the severely damaged area using a new product which delivers fiber to the cell provider’s network interface (making BellSouth’s network less vulnerable to power interruptions). Cell providers provide backup generator to maintain service.

Engineering Challenges & Solutions: 

Engineering Challenges & Solutions Chalmette Former vacant lot became a FEMA trailer park in a short timeframe No existing facilities, utilize fiber and electronics to provide facilities

Engineering Challenges & Solutions: 

Engineering Challenges & Solutions Beryl Street – Orleans Parish New fiber fed facilities on a raised platform to provide service to repopulating neighborhood

Damage Prevention - Elevated Digital Carrier Sites: 

Damage Prevention - Elevated Digital Carrier Sites Fiber Carrier Facility on Raised Platform

Removing Damaged Facilities: 

Removing Damaged Facilities Chopper truck crews removed miles of damaged underground copper pulp cables, creating the pathways for fiber facilities and future technologies on raised platforms that can withstand flooding Placing Innerduct in the conduit run in advance of placing fiber cable for future voice and broadband services

Damage Prevention - Elevated Sites : 

Damage Prevention - Elevated Sites Engineered elevated structures to mitigate damage by flooding Fiber feeder cables not susceptible to damage by flooding Acquiring Right Of Way and access was challenging-aesthetics Facilities were rearranged to reduce the number of interfaces or cross connect points and ensure that new locations are elevated

Elevated Service to Restored Cell Site: 

Elevated Service to Restored Cell Site St. Bernard Parish Fiber fed location providing latest technology Elevated platform for electronics serving cell site Provides protection against flooding

Emergency Back Up Power for Critical Sites: 

Emergency Back Up Power for Critical Sites Natural Gas 25 KW Emergency Generator to power Fiber Carrier Facility Provides back up power to ensure that service is not disrupted in case of a storm or power outage Elevated to prevent damage from flooding

Wireless Broadband Service Deployed: 

Wireless Broadband Service Deployed

Emergency Preparation: 

Emergency Preparation Negotiated contracts with local parking garages to vertically evacuate engineering and low profile construction and installation vehicles in New Orleans prior to future storms. Evacuation Plans and timelines established for larger vehicles to emergency center in Baton Rouge. Negotiated Contracts for emergency fueling and fuel distribution to critical network elements pre and post storm. Alternative emergency operations center established in Baton Rouge for evacuation of key personnel based on local guidance.

Emergency Preparation: 

Emergency Preparation Established dedicated liaisons and backups to Parish Emergency Operations Centers to work with local officials on critical issues such as access, essential needs, service priorities. Alternative communications devices secured and distributed to all key management personnel to ensure communications following storms. Planned disaster drills and scheduled tabletop exercises to test emergency operations plans. Emergency Operations Plan communicated to all levels of management. Local plans synchronized with regional EOC.
