Abstract
The Logan Section of the City of Philadelphia, that encompasses 17 city blocks and includes 997 "row type" dwellings, was constructed in the early 1900s. It is reported that settlement of these structures has continued since their construction. In 1986, a Geotechnical Investigation, commissioned by the City of Philadelphia, revealed that a total of two to three feet of settlement, with as much as one to two feet of differential settlement, has taken place. Recent measurements indicated that settlement is still in progress. This settlement has resulted in severe structural damage and, in some cases, collapse of the buildings. One hundred (100) homes have been declared imminently dangerous, 110 homes have been declared dangerous, and the remaining homes are considered moderately damaged. This paper discusses the probable causes of settlement, and evaluates the geotechnical characteristics and properties of the ash and cinders. These characteristics are considered the prime cause of the problem at the Logan Section.

Distress to Structures on Loose Ash and Cinder Fills
The Logan Section of the City of Philadelphia, that encompasses 17 city blocks and includes 997 "row type" dwellings, was constructed in the early 1900s. It is reported that settlement of these structures has continued since their construction. In 1986, a Geotechnical Investigation, commissioned by the City of Philadelphia, revealed that a total of two to three feet of settlement, with as much as one to two feet of differential settlement, has taken place. Recent measurements indicated that settlement is still in progress. This settlement has resulted in severe structural damage and, in some cases, collapse of the buildings. One hundred (100) homes have been declared imminently dangerous, 110 homes have been declared dangerous, and the remaining homes are considered moderately damaged. This paper discusses the probable causes of settlement, and evaluates the geotechnical characteristics and properties of the ash and cinders. These characteristics are considered the prime cause of the problem at the Logan Section.
