The report, scheduled to be completed on Dec. 1, by the Harris County Housing Authority indicates that Ike will be far costlier than any other Houston-area storm in recent memory.
Single-family homes accounted for most of the damage, with a midrange estimate of $7.6 billion. Apartments sustained about $830 million in damage and mobile homes about $1.7 million, the Houston Chronicle reported Monday in its online edition.
Total residential and commercial damage from Hurricane Alicia in 1983 was estimated at $2 billion -- about $4.11 billion adjusted for inflation -- while Tropical Storm Allison in 2001 caused an estimated $1.76 billion in residential damage, about $2.1 billion adjusted for inflation.
Officials said the Ike study will help local and federal officials project funding needs for housing assistance programs.
Ike blasted ashore near Galveston on Sept. 13, flattening buildings and killing at least 37 people in Texas. The storm is the most expensive in Texas history, with an estimated price tag of $11.4 billion.
