We have the <br /> following comments with regards to engineering matters: <br /> • The survey should show existing contours extending 50" beyond all lot lines. <br /> • All existing structures antl trees shoultl be shown on the survey. In addition, the City should <br /> consider the extent of tree removals as a result of the proposed construction. <br /> • In order to tletermine existing antl proposed drainage patterns, more information, such as spot <br /> elevations, shoultl be shown along Fox Street, especially at the proposetl tlriveway. It may be <br /> necessary to atld a culvert underneath the driveway to allow drainage to continue east along Fox <br /> Street. <br /> • All existing contours shoultl be labeled. <br /> • The City should be aware that the proposed septic sites overlap. <br /> • We are concerned with the proximity of the swale to the southwest corner of the house, in adtlition <br /> to the flat grade of the swale. We would recommentl that the swale have a slope of at least 2%. <br /> • The proposed house elevation and adjacent grading is significantly higher than existing grades, <br /> requiring a large amount of fill to be used. The applicant should justify the reason for this. <br /> If you have any questions, please call me at(651) 604-4863. <br /> Yours very truly, <br /> BONESTR00 <br /> � � <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br />
