The site <br /> improvements include constructing an addition to the existing home and ass ciated grading. We have the <br /> following comments with regards to engineering matters: <br /> • The plans include a note that specifies sod placed on slopes exceedin 5%be staked. This will only <br /> work if the stakes are long enough to anchor the sod.The city should' pect these areas,particularly <br /> after rain events to verify the swale and sod stability. Silt fence shoul remain in place downstream <br /> frorn the swales until the root system is established. <br /> • The plans specify 2-inch to 3-inch rip rap at the downstream end ofthe riveway swale.The size of rip <br /> rap shown is too,small and will tend to migrate during larger sto eyents. The plans should be <br /> revised to specify a minimum diameter of 9-inches for all rip rap. Try g to turn the water from this <br /> driveway swale away from the rear of the home and to the proposed si e yard swale is a concern.The <br /> final grading should be inspected and approved by the ciry to veri the swales were constructed <br /> correctly. <br /> • The city has a sanitary sewer line along the lake side of the horne.The pplicant should provide a 20- <br /> foot wide sanitary sewer easernent centered over the pipe if one does ot already exist. <br /> If you have any questions please ca11 me at(651)604-4863. � . <br /> Yours very truly, <br /> BONESTROO, ROSENE, ANDERLIK&ASSOCIATES, INC. <br /> �Q7�"1 � <br /> Tom Kellogg - <br /> Cc: Greg Gappa, City of Orono <br /> St. P�ul, St, Cloud, Rochester, MN • .Milw�ukee, WI Chic�go, IL <br /> � .
