The mayor of Miami is asking residents for patience and understanding as the effort continues to restore electrical service.

“It is hard to ask for people's continued patience,” Mayor Brent Brassfield said at Wednesday's 3 p.m. city briefing. “We want to be informative about when power will be restored, but, honestly, we often don't know what we face until we get in there to do the work.”

Crews are present in all four city quadrants today and working to restore power to as many people as possible, according to Miami Utility Department supervisor Dave Matthews.

Matthews anticipates that utility crews and tree trimmers will be “in great shape” by Saturday and will have “done as much as they can do” until licensed electricians take care of the residential end of service-line problems.

All feeder lines - the city's main transmission lines - are functioning.

Restoration of primary lines is between 65 and 95 percent complete and secondary line repairs are between 50 and 95 percent complete.

The biggest problem facing residents who remain without power is the delay in getting electricians on site to make residential repairs.

Additionally, city engineer Jerry Ruse said supplies are becoming scarce and electricians are now making trips to neighboring states to get materials.

“Those repairs have to be done before the city can reconnect service lines to a residence,” Ruse said.

Frustrations are mounting in the city's emergency operation center as calls come in from angry customers who report to have no damage to their meter boxes, but are still without power.

Matthews said Wednesday that the objective of the utility crews is to restore power to as many people as possible in the least amount of time.

“I would rather spend 30 minutes and get power to 30 people than to spend an hour to get service to one person,” Matthews said.

As a result, areas where there is a high concentration of service line problems that require residential repairs will be a secondary priority to areas where efforts will benefit the greatest number of utility customers.

Utility officials are making no guesses as to when power could be restored to homes where meter boxes are torn away from structures.

Also noted in Wednesday's briefing were the following:

€ More than 80 loads of limbs have been brought to the city's transfer station. There, just south of the airport, utility customers can bring limbs and storm debris at no charge from 8 a.m. to 4 p.m. Monday through Friday and from 8 a.m. to 2 p.m. on Saturday.

€ There will be no burn permits issued in by the City Fire Department until brush and debris is cleared.

€ The Miami shelter, located at the First Assembly of God Church on Steve Owens Boulevard, remains open and is serving approximately 150 occupants.

€ A chainsaw crew, organized by the Southern Baptist Convention, will arrive in town today to begin assisting residents with clearing debris from their property.

€ Power is expected to be restored to Rokdale Elementary School today.

€ The Federal Emergency Management Agency has opened a damage assessement hotline for residents to report storm damage. The number is 866-560-7584.

€ One city employee was injured Wednesay after a tow chain broke and snapped back into the cab a city truck. Ryan Edmondson's injury is the first reported since the onset of the ice storm.

Note: The information listed above does NOT include customers waiting for service line repairs - the lines that carry power from secondary lines to a household or business. City officials estimate that, by Friday, utility crews will have “done all they can do” until licenced electicians make the necessary repairs to residences where meter boxes and weather heads were ripped away from structures. Local electricians have indicated that waiting lists for meter box repairs are long, most exceeding 100 requests for service.
