Gaffron, Asst Planning & Zoning Administrator <br />March 30, 1990 <br />Subject: #1519 Fullerton Properties - Willow Drive/County Rd 6 <br />Sketch Plan - Septic Concerns <br />I have transferred the soil survey information to a copy of <br />the proposed plat, and would make the following preliminary <br />comments for sketch plan review; <br />1. Soils on the west half of the site are mainly LeSueur <br />loam, slopes generally 6% or less and water table generally <br />no higher than 3' below the surface. The lots designated as <br />Lots 1, 2 and 3, Block 1, and Lots 1 and 2 of Block 2, have <br />substantial areas of LeSueur loam and probably will find <br />suitable sites for mound systems. <br />2. Lots 3 and 4, Block 2 contain areas of Kilkenny and <br />Lester clay loam soils which generally are a little heavier <br />clay soils. Again, these lots would probably require mound <br />systems and both appear to have some area of acceptable <br />slopes. <br />3. The existing farmstead in Lot 5, Block 2 (2225 Sixth <br />Avenue North) has one 1,000 gallon pre-cast concrete tank <br />west of the farm house, and drainfield that is unknown. <br />Notwithstanding concerns about drainage through the west end <br />of this lot, there may be suitable expansion sites west of <br />the house. The higher ground on which most of the buildings <br />are located is a Hayden clay loam, often requiring mound <br />systems due to slow perc rate, with the areas west of the <br />house appearing to be a Glencoe silty clay loam which often <br />precludes the use of any system. <br />4. Lots 6, 7, 8 and 9 of Block 2 contain substantial areas <br />of Glencoe soil which often has water table at the surface <br />during the wet season. Lots 6 and 7 would appear to have a <br />drainageway from the north bisecting these lots into a front <br />and rear portion. Lot 6 may have some mound sites on the <br />fringes of the Glencoe at the front or rear of the lot. Lot <br />7 will have an extremely difficult time trying to find <br />drainfield sites that are more than 75' from the designated <br />wetland area. Lots 8 and 9 are also quite low, containing <br />mostly wet soils. These two lots might find suitable mound <br />sites near the road, probably ending up in front yard areas. <br />Both Lots 8 and 9 have a number of drainage concerns, as <br />they are the receiving area for overland flows from the <br />west.
