Site drainage and constructability factors are the significant <br />engineering issues. <br />*• •pansion is 25* x 10“. The construction of the room will necessitateThe proposed storage roo< <br />removal of p^ '^e e ng timber retaining wall and fence along the east side. The <br />construction \ block the onfy available drainage route for the south parking lot. We <br />recommend tlu .»uniinoiis drainage swale be constructed along the east side of the proposed <br />insion. The swale should be a minimum of 3' wide to allow for snow removal. The <br />rirni^tmcfi^ of the swale will require that the retaining wall and fence be reinstalled <br />■ppiofldmatefy 4* to 6’ east of the present lor»tion. We recommend that the large existing <br />• <br />cottonwood trees be removed as th^ would present a safety concern because much of the root <br />foundation needed to support the trees in strong winds would be removed. <br />Hie owner diouid be required to provide a new plan with the modified drainage swale, retaining <br />waO fence location shown. The bituminous swale should be sloped away from the buildiiig <br />at a l/2f/ft slope. The swale, retaining wall antf.. ice should be tapered back at both ends of <br />the buil^ to allow a smooth transition into the .^ting topography. (See attached sketch). <br />Please contact this office if you have any questions. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERUK A ASSOCIATES, INC <br />1>. <br />Shawn D.
