'( '��r��- �.��, NO. 2761 � �;i•.�-.<Slr'..n,�. ....---,.•- . .... �;-°�� `�' As part of the rip-rapping project, the applicant - was required to maintain drainage through the rip-rap via a draintile, which was a necessary part of a swale system required in the 1975 subdivision approval that created this lot. The conditions of that subdivision approval required that a swale be maintained generally along the west end of the property to continue drainage towards the lake from the neighboring property from � which the lot was split off. Such a swale has always been in place, and was required to be maintained in a functional manner. Grading within 20' of the shoreline was necessary to maintain proper elevations for the discharge tile line through the rip-rap. This grading work was not brought to the attention of City staff until after the rip-rapping project was underway. C) In conjunction with remodeling of the pre-existing residence on the property, applicants constructed a basement access door at the west end of the house. While a review of the plans later indicated that this door had been proposed, no grading plan accompanied • that plan to inc3icate that outside graae changes would be proposed or necessary. In order to accommodate gravity drainage away �from that basement level doorway to the adjacent swale area, the swale was lowered at the west end of the house approximately 3' , in the 75-250' zone. At the 75' setback line, the swale was lowered approximately 1' from its pre-existing condition to accommodate drainage from this doorway. As the swale headed nearer the shoreline, the extent of grade elevation changes in the 0-75' zone decreased to a few inches. D) The Planning Commission found that the impact of the deepening of the swale in the 0-75 ' zone as described above is minor. The grading does not redirect arainage on the property, but maintains the pre-existing drainage pattern which was required to be maintained when this lot was subdivided. Furthermore, lowering the pre-existing swale by one foot or less in the 0-75' zone to accommodate gravity drainage away from the basement access door would be preferable to requiring the applicant to crib an area near the doorway leaving a stairwell that could cause potential basement water problems.
