Additionally, a topographical survey of the roperty containing a plot of the drainfield sites has been ubmitted ��9� I�make the following comments regarding each proposed lot: Lot 1, Block l. Primary and alternate sites have been located. Both t�re sites require a mound system due to high seasonal water tables. Slopes range from 2$-6�. These two sites are about 50 ' from a proposed detention basin, but should not affect nor be affected by that basin. The sites should be totally fenced off with snow fencing before any road or detention basin construction takes place in the subdivision. Lot 2, Block 1. Primary and alternate sites have been located, and both sites have soil and water table conditions to allow for a trench drainfield system. With the proposed house site at the south end of the lot, there should be no problem preserving these sites. Again, the drainfield area should be fenced off to keep all traffic away during road and de�ention basin construction. , ....._..._,�.�..��.. _�..�_. , .. _... .. .._.. ,�,. Lot 3 , Block l. Again, primary and alternate drainfield � ,sites are suitable for trench systems. The two sites are at the rear of the lot. With the most likely house site near the front of the lot , these sites appear to be very suitable. ,, _ _ .._ � ILot 4, Block 1. Primary and alternate drainfield sites are �located on the knob at the southwest corner of the property. Both sites require mound systems. With the house site suited for a walk-out to the northeast, a driveway would likely be centered on the lot east of the drainfield sites. Slopes are in the range of 3�, and not accurately ref lected by the topographic map. It is critical to totally enclose these sites with snow fence prior to any road construction work, since the sites are very close to the road. Also, road grades and cuts should be reviewed to verify that the roadwork will not cut into site #2. Lot 5, Block 1. Primary and alternate drainfield sites are located to the rear of the property on slopes of 0-2$. Both sites require a mound system. With the probable house centrally located o� the lot, these sites appear ery suitable.
