We have resnewed the ceiliricale of surv ey and proposed grading plan for the home additions to 2941 Casco Point Road. W'e haw the following comments with regards to engineering matters: • The proposed silt fence immediately north and south of the home is shown running up the hill. This silt fence configuration will concentrate flows draining towards the lake and increase erosion potential adjacent to the home. The silt fence north and south of the home should be eliminated and the silt fence shown lakeside from the home should be e.xtended at least 10-fect on to the adjacent properties. All silt fence should be heavy dut>’ with steel t-posts. All erosion control should be installed, inspected and approved by the City prior to any work on the site. • The drawings showr the existing home and a proposed addition within 7-feet of the south lot line. It appears temporary easements will be necessary from the property owner to the south to complete the construction and install the proposed draintile. • The proposed swale shown on the street side of the home drains southerly and appears to discharge onto the neighboring property. The swale should be extended around the home and towards the lake to convey (lows away from the neighboring property. A temporary construction easement will be required to complete this work. • Rain gutters should be installed on the home to direct water away from adjacent properties, particularly along the south side of the property. • The dnvaway shown to the property is mostly on the adjacent lot. A driveway easement should be acquired if one does not already exist. Please contact me at (651) 604-4863 if you haw any questions regarding this maner. Yours very truly, BONESTROO.
