Sketch Plan - Septic Concerns
I have transferred the soil survey information to a copy of
the proposed plat, and would make the following preliminary
comments for sketch plan review:
1. Soils on the west half of the site are mainly LeSueur
loam, slopes generally 68 or less and water table generally
no higher than 3' below the surface. The lots designated as
Lots 1, 2 and 3, B1ock.Y, and Lots 1 and 2 of Block.2', have
substantial areas of LeSueur loam and probably will find
suitable sites for mound systems.
r
2. Lots 3 and 4, Block ,e contain areas of Kilkenny and
Lester clay loam soils which generally are a little heavier
clay soils. Again, these lots would probably require mound
systems and both appear to have some area of acceptable
slopes.

3. The existing farmstead in Lot 5, Block,2'(2225 Sixth
Avenue North) has one 1,000 gallon pre -cast concrete tank
west of the farm house, and drainfield that is unknown.
Notwithstanding concerns about drainage through the west end
of this lot, there may be suitable expansion sites west of
the house. The higher ground on which most of the buildings
;are located is a Hayden clay loam, often requiring mound
systems due to slow perc rate, with the areas west of the
house appearing to be a Glencoe silty clay loam which often
precludes the use of any system.

4. Lots 6, 7, 8 and 9 f B lockjl contain substantial areas
of Glencoe soil which - "ten has water table at the surface
during the wet season. -)ts 6 and 7 would appear to have a
drainageway from the r .ti7 bisecting these lots into a front
and rear portion. I may have some mound sites on the
fringes of the Glencoe the front or rear of the lot. Lot
7 will have an extremely difficult time trying to find
drainfield sites that are more than 75' from the designated
wetland area. Lots 8 and 9 are also quite low, containing
mostly wet soils. These two lots might find suitable mound
sites near the road, probably ending up in front yard areas.
Both Lots 8 and 9 have a number of drainage concerns, as
they are the receiving area for overland flows from the
west.
