In conjunction with lowering that culvert, applicant also regraded the swale in the 0-75' zone to accommodate drainage away from the walk-out door which was constructed to the basement area. •'’his walk-out door was approved by the building inspector on the remodeling plan, but no indication of site grading to accommodate that door was submitted. Staff had no indication that the applicant intended to lower the grade between the door and the shoreline. A door well could easily have been constructed to accommodate that doorway without the need for grading in the 0-75' zone.5. The applicant notes that as part of the original subdivision to create this lot, a swale along the west lot line was required and had been installed in 1975. The grade at the wall in the location of the basement doorway previously was approximately 3' higher and the swale just continued along the west side of the house from the front yard out to the lake. It is staff's opinion that the reduction in grade in the 0- 75' within 20' of the shoreline is necessary for drainage maintenance. Any grading work from 20' to the house doorway (about 100' back from the shoreline) was not necessary except to provide gravity drainage away froin the basement door. Discussion - Except for the area of the swale, the lakeshore yard has been restored back to original grades, i.e. the temporary storage fill has been removed and the ruts created by the trucks carrying rip rap boulders, have been refilled and top-dressed. The questions posed to the Planning Commission are two-fold: A) Should a conditional use permit be granted after-the- fact for grading work within 20' of the shoreline to maintain the culvert through the rip rap and the swale, which were required as part of the 1975 subdivision? B) Should the additional depth of swale be allowed to accommodate the basement doorway, or should that area be restored to pre-existing grades and some sort of well/step system be constructed for the doorway, totally in the 75- 250' zone? The grade at the basement doorway has been dropped approximately 3'. In the 0-75' zone, the lowering of the grade at the bottom of the swale ranges from just a few Inches to approximately 12 inches to 18 inches at the 75* setback line. } - CT . /A- ^ _ tJ - N
