P.O. Box 66 <br /> Crystal Bay, Minnesota 55323 <br /> ` Subject : Preliminary Subdivision <br /> � Ja.mes Lawrence Property (#323) <br /> s Dear Aank: <br /> � On November 11, 16 and 21, I received additional information <br /> � on the subject project from Gordon R. Coffin Co. , Iric. I am <br /> of the opinion that the proposed subdivision is not acceptable <br /> � and have the following comments: <br /> � 1. Access to Lots 4 and 5 appears to be through a private <br /> . road extending from County Road No. 6 to the west lot <br /> lines of Lots 4 and 5. <br /> � 2. The dry buildable lot sizes for Lots 3 and 4 are based <br /> � on the gross lot area which includes the �reek that drains <br /> through those lots. In the November 21 submittals, a <br /> � 20-ft. drainage easement was shown along the entire length <br /> • of the creek. <br /> + 3. A large portion of the soils in the subdivision have been <br /> classified as Hamel or Glencoe soils. These soils typically <br /> � are encountered in areas having very high water tables. In <br /> the case of Glencoe soils, the ground is frequently ponded. <br /> � Both of these soil types are unsuitable for septic systems. <br /> � 4. Nearly all of the subdivision that is not classified as <br /> � Ha.mel or Glencoe soils has slopes in excess of 12�. Again, <br /> • these areas are -not recommended for on-site septic systems. <br /> � An estimate of unsuitable soils for on-site septic system <br /> by lot is as follows : <br /> • <br /> , Lot l: 50� Glencoe soils and the remaining 50;6 has <br /> slopes in excess of 12°b. <br /> � <br /> Lot 2: 30`,� Glencoe soils and 50;� has slopes i.n excess <br /> � of 12�. <br /> � Lot 3 : 40� Hamel soils and the remaining 60� has slopes <br /> � in excess of 12� . <br /> • <br /> 12805 OLSON MENFORIAL HIGHWAY, MINNEAPOLIS, MINNESOTA 55441 TELEPHONE 1612) 5593700 <br /> • 22 NORTH MAIN STREET, HUTCHINSON, MINNESOTA 55350 TELEPHONE 1612) 879-8029 <br /> SOUTHWEST ENGINEERING DIVISION, MARSHALL, MINNESOTA 56258 TELEPHONE (507) 532-5820 <br /> � prnnted on recycled pa�er <br />
