We have the following comments with regards to engineering matters: <br />• The proposed silt fence immediately north and south of the home is shown running up the hill. This <br />silt fence configuration will concentrate flows draining towards the lake and increese erosion potential <br />adjacent to the home. The silt fence north and south of the home should be eliminated and the silt <br />fence shown lakeside from the home should be extended at least 10-feet on to the adjacent properties. <br />All silt fence should be heavy duty with steel t-posts. All erosion control should be iiistalled, inspected <br />and approved by the City prior to any work on the site. <br />• The drawings show the existing home and a proposed addition within 7-feet of the south lot line. It <br />appears temporary easements will be necessary from the property owner to the south to complete the <br />construction and install the prop jed draintile. <br />• The proposed swale shown on the street side of the home drains southerl} and appears to discharge <br />onto the neighboring property. The swale should be extended around the home and towards the lake to <br />convey flows away from the neighboring property. A temporary construction easement will be <br />required to complete this work. <br />• Rain gutters should be installed on the home to direct water away from adjacent properties, <br />particularly along the south side of the property. <br />• The driveway shown to the property is mostly on the adjacent lot. A driveway easement should be <br />acquired if one does not already exist. <br />Please contact me at (651) 604-4863 if you have any questions regarding this matter. <br />Yours very truly. <br />BONESTROO, ROSENE.
