This evaluation is based on my observations during a site visit on August 4, 2016, and <br /> information you provided in an email on August 3, 2016, including as-built survey information and a <br /> sketch of a swimming pool post footing detail indicating that the pool footing loads are being supported <br /> below the influence of the retaining walls. <br /> The construction of the retaining walls is structurally stable and in general conformance with boulder <br /> retaining wall and construction industry standards. The walls were constructed with stone of sufficient size <br /> and setback. Other typical construction details such as use of drainage elements also appeared to be <br /> followed correctly. As is normal for boulder retaining walls of this type, some wall movement and soil <br /> settlement should be expected. I recommend that concentrated areas of surface water should be directed <br /> away from the walls. Several photos were taken for documentation, some of which have been provided <br /> as part of this report. <br /> This evaluation was performed using the design guidelines presented in the third edition of the"Design <br /> Manual for Segmental Retaining Walls" (DMSRV1n published by NCMA in 2009. Direct all surface <br /> drainage away from the retaining walls. If soil conditions, proposed layouts, or other design parameters <br /> vary from that assumed, a revised analysis might be needed. Please call me if you have any questions or <br /> need more information. Thank you. <br /> Sincerely, <br /> ���;tl1f��;� , <br /> �j�%' /�- `�,;`,.��.���,����t¢d,. <br /> + ` ,\ j'.' � .. ,��� �,� !� �. <br /> .. ;- ". .._. _ ' .— ��/ •4'i <br /> .-"-`_�;` ',✓ _ ;dSE . <br /> Paul Schimnowski, PE ' �F,���N���'�- � �,-_= <br /> �: � �8 t�t? �:�.
