We have the following comments with regards to engineering matters: <br /> • The applicant needs to provide engineered design information for the 11-12 foot high retaining <br /> walls leading into the garage and any other retaining walls that are greater than four feet in height <br /> on the site. <br /> • On the east side of the site,drainage is directed over the adjacent property. The plan shows a <br /> proposed drainage easement. The applicant should provide these easement documents for the <br /> city's review prior to approval. <br /> • The revised plan shows grading matching into the bottom of the existing boulder retaining wall <br /> along the south property line. This plan appears to keep the grading entirely on the applicants <br /> property and maintains the current height of the retaining wall. <br /> • Final plans should contain erosion and sediment control information. <br /> If you have any questions,please call me at(651)604-4894. <br /> Yours very truly, <br /> BONESTROO, ROSENE,ANDERLIK&ASSOCIATES, INC. <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br /> Bonestroo recently merged with DSU,bringing together some of the best regional talents in engineering,architecture,planning,landscape architecture, <br /> and urban design.
