Prior to making any field changes <br /> that would increase the height of the proposed retaining walls, engineered design and details must <br /> be submitted for review and approval. <br /> • The garage floor drain may not be able to be connected to the sanitary sewer, The applicant <br /> should discuss available options with the city's building official. <br /> • Revise CBMH 3 Detail to reflect City Standard Detail Plates(See attached detail plates), <br /> If you have any questions, please call me at(651)604-4894, <br /> Yours very truly, <br /> BONESTR00 <br /> �--. <br /> � `r—.�� i . �-�� <br /> ---_ <br /> Darren Amundsen <br /> Cc; Tom Kellogg <br />
