Box G6 <br /> Crystal Bay, Minnesota 55323 <br /> Subject : Preliminary Subdivision <br /> James Lawrence Property (rr323) <br /> . Dear Hank: <br /> On November 11, 16 and 21, I received additional information <br /> on the subject project from Gordon R. Coffin Co. , Inc. I am <br /> of he opinion tbat tbe proposed subdivision is not acceptable <br /> and have tbe following comments: - <br /> 1. Access to Lots 4 and 5 appears to be through a private <br /> road extending from County Road No. 6 �o 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 -�ubmittals, 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 Ha.mel 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 /> Hamel or Glencoe soils bas 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 /> Lot 1: 50�, Glencoe soils and the remaining 50% has <br /> � slopes in excess of 12�',. <br /> Lot 2 : 30p Glencoe soils and 50°G has slopes in excess <br /> of 12�. <br /> • Lot 3 : 40;�6 Hamel soils and tbe remaining 60ro has slopes <br /> in excess of 12p . <br /> � 12SJ5 OLSON MEh10R1AL HIGH�VAY, h11NNEAPOLIS, MINNESOTA 55441 TELEPHONE (612) 5593700 <br /> 71 NORTH MAIN STREET, HUTCHINSON, MINNESOTA 55350 TELEPHONE (612) S79-S029 <br /> SOUTHWEST ENGINEERING DIVISION, MARSHAIL, MINNESOTA 56258 TELEPHONE (507) 532-5820 <br />
