Provide information or a detail for any special construction or soil information <br />for 2’ drainage ditches <br />(Plowe 10/15//24) A note has been added indicating that the topsoil is <br />to be removed and replaced with a sand/topsoil blend. <br />(WSB 11/6/24) Provide detail showing the extents of the soils amendment <br />•Ditches will need to demonstrate permeable material <br />(Plowe 10/15//24) A boring in the ditch location shows SP-SM soils which <br />are generally silty sands. <br />(WSB 11/6/24) Complete <br />•Recommend digging down to permeable soils and installing sand/compost <br />mix to final grade to better promote infiltration and reduce standing water in <br />a rain event <br />(Plowe 10/15//24) A note has been added indicating that the topsoil is to be <br />removed and replaced with a sand/topsoil blend. <br />(WSB 11/6/24) Provide detail showing the extents of the soils amendment <br />4.Provide ditch High Water Level (HWL) on plans <br />(Plowe 10/15//24) The basin’s HWL has been noted on the plans. <br />(WSB 11/6/24) Complete <br />5.Relocate existing shed outside of 5' easement/setback <br />(Plowe 10/15//24) It is noted that the shed (a portable smokehouse) will be <br />moved outside of the drainage and utility easement and 5-ft setback. <br />(WSB 11/6/24) Complete <br />6.Relocate existing fire pit outside of 20' distance from property line and 25' <br />distance from structures <br />(Plowe 10/15//24) A note has been added indicating that the fire pit should <br />be moved to meet the above required distances. <br />(WSB 11/6/24) Complete <br />7.The current 906.8 'berm' near the southeast corner of Lot 4 would spill over <br />the 906.5 spot elevation on the eastern property line <br />•Raise berm and initial EOF to east to 907.2 (Basin to the east is 'land- <br />locked' and will ultimately flow back to the west) <br />(Plowe 10/15//24) Berm has been raised as requested. <br />(WSB 11/6/24) Complete <br />•EOF for basin to the east is towards this development and would be at <br />907.2
