Olson <br />Susan M. Eberltn <br />/ <br />[ i <br />We have reviewed the plans submitted on the Ulrich property for the seawall, <br />foundation drains and heat pump discharge. <br />The seawall plan should include the detail information submitted when the <br />existing wall was built. The certification by the engineer should not contain <br />the term "appears to be adequate". The Owner's engineer should check out the <br />design and certify that what is proposed meets standard design criteria. <br />» <br />The foundation drain plan should be modified to stop the drain field 10 feet <br />short of the lake shore. The drain tile should then be connected into a dis­ <br />tributor box and an overflow line provided. <br />The heat pump discharge line plan should provide the following additional <br />information: <br />* 1. Average discharge <br />2. Peak discharge <br />3. Velocity of water exiting holes in last pipe length <br />4. Method of anchoring Co lake bed <br />5. Improved profile information with station of point elevations indica­ <br />ted include station at lake shore <br />6. Well data'depth, size, capacity <br />7. Discharge temperature of water - summer and winter <br />The depth of the discharge line is shown approximately 5 feet below the normal <br />water elevation. Is this adequate clearance for boats which operate within <br />100 feet of the lake shore? The owner will also need a DNR permit for instal­ <br />lation of the discharge line in the lake bed. <br />5706d <br />Page 1, <br />30 Year <br />Anniversary
