Site#4: <br /> Construction of the detached garage was completed last year. Concern was expressed as to the <br /> capacity of the segmental masonry retaining wall between the new detached garage and the existing <br /> house. <br /> �.:;te, .; ,r . ,w . <br /> � � '�"��� rt� <br /> We visited the site August 14, 2014 �������"������` , ������ ' � �-�_~� <br /> G <br /> to observe the wall. �: -- <br /> The East portion was 44" long & " `� - � ���`' `�- <br /> , � `:��,r�- <br /> 51 '/2" high against the existing �.-. .Fl� ���—�' ,.,�,,�, �'V` <br /> _ � �� <br /> house.

A stability analysis of this gravity Wdll indicates the factor of safety from overturning <br /> is greater than 2.0(code minimum is a 1.5 factor of safety). <br /> I believe this addresses your immediately concerns.
