Hakanson <br />Anderson <br />Assoc.,Inc. <br /> <br />Engineers, Surveyors & <br />Landware Architects <br /> <br />February 3, 1987 <br /> <br />Mr. Kenneth Peterson, Chairman <br />Ramsey Planning & Zoning Commission <br />city of Ramsey <br />15153 Nowthen Boulevard N.W. <br />Ramsey, MN 55303 <br /> <br />Re: Preliminary Plat of Now & Then Estates <br /> <br />Dear Mr. Peterson: <br /> <br />Since our letter of December 29, 1986, the developer has provided <br />soil borings, future subdivision plan and a statement on source of <br />water and sewage disposal systems for the plat. The square footage <br />of the proposed lots was previously provided. <br /> <br />In review of the soil borings and soils report, the water table is <br />reported at approximately elevation 870. This would allow for the <br />installation of standard wastewater disposal systems. However, <br />mottling was present in test holes two and four at a depth of 1.5 <br />to 4.5 feet below the surface. The state and city codes require <br />three feet of separation between mottling and the drain field. <br />Therefore, we would recommend additional boring and percolation <br />tests be provided in the vicinity surrounding test holes two and <br />four. <br /> <br />In reviewing the items on page two of our letter of December <br />29, 1986, no additional or revised information has been pro- <br />vided by the developer to address those items. Therefore, we <br />would recommend that those items be resolved along with pro- <br />viding additional soil boring and percolation tests that <br />justify installation of on-site wastewater disposal systems <br />prior to approval of the preliminary plat. <br /> <br />777.
