The boulder wall <br /> varies in height from 2 ft. to S'-6" tall. Engineering certification is required in your <br /> municipality for any retaining wall exceeding 4 feet in height The overall length of the <br /> wall is approximately 75 ft. and about 25 feet of the total let,�th of the boulder wall <br /> exceeds 4 feet in height. The wall was built with boulders averaging 3 ft. in diameter with <br /> an average front batter (vertical slope) of approximately 15 degrees. Filter fabric was <br /> draped behind the baulders. The boulder wal] in its closest proximity is about �0 ft. from <br /> the northeast corner of the attached garage The boulder wall does not retain any soil <br /> required for the stability of the house or garage foundation. <br /> In my opinion, as a Registered Professional Engineer in the State of Minnesota, based on <br /> the wall construction as described above, this design meets my standards for boulder <br /> walls and is therefore acceptable. This report constitutes certification of the boulder wall <br /> desi�n and may be submitted to the local building inspector. <br /> Please feel free to contact me with any questions or comments regarding this report. <br /> "'aq1111'tl4isf{fllliifri,f <br /> SincerelY� ,�,,���`°�c��,� G. ��,.��,':. <br /> :��,�; '' .��'; <br /> Stroh Engineering � . °•�'' <br /> � �e �FG��T��ED � <br /> � _ � °t`,�� ;ryC'�'�t`�,'i`�P.'L _ <br /> � � � P�� ���'�� � = <br /> t�`a1�it.l�.� -�' <br /> =¢��`, 1�26� :�.�. � <br /> f J �r�p � <br /> � • gvA \ <br /> Bernie Stroh, P.E.
