LINDQUIST & VENNUM J Ms. Jeanne A. Mabusth April 23, 1979 Page 2 is taken at a point very close to the southwest property line with the Smerlings. From the previous testimony and with this diagrcun, I believe it should be clearly demonstrated that there was a flat area where the foot of the wall is and that there were two drop off points, one drop off from the lawn to the flat area, and the second drop off from the flat area down to the lake. There had been some belief on behalf of the staff that there had been no such drop off, but that is not £»upported by the engineering data. With the original grade being clearly shown, one can see that the height of the wall proposed above the grade is not more than the allowable 3 1/2 feet. Second, the engineer was asked what the minimum and maximum height of the wall could or should be. From our point of view, 3 1/2 feet is adequate to control the drainage and otherwise make a nice appearing wall. Please note that the northeasterly southwesterly drainage pipe is set back, that is southeasterly from the wall, and it is desirable that the ground level slope to the southeast from the wall such that storm water run off from the house and terrace area does not pool against the wall itself, but rather pools in the swail where the drains are. Third, the question was asked whether the wall could be moved back 15 feet and still do the job. From our point of view anything can be done, but the real question is what’s the practical way to solve the problem. He feel that putting the wall where it is at the natural drop off point was the preferred method of adding support to the hillside because the ground was left largely undisturbed which is generally more conducive to cohesive strength of the soil, and in addition advantage was taken of the natural drop off such that there was not a large amount of grading necessary. Finally, with the placement of the natural drop off where it is, that is the point at which support is needed, not a point artifi cially further to the southeast. That is to say in our engineer’s opinion, from his*previous letters, the place to buttress the hillside is at the natural drop off, not at a different place.
