Zoning File #1255 Page 2 C. Drainage from the revised driveway area. C. The prop.)sed removal of live 30' tree to accomodate new driveway, 25' from shoreline. Hardcover Staff has reviewed the site hardcover which is presented in Exhibit F. The hardcover existing is 30.6% all in the 0-75' zone. The proposed changes to hardcover include revising the 2055 s.f. existing driveway down to 1420 s.f., and revising the existing 135 s.f. entryway to a 252 s.f. entryway in conjunction with the appropriate sidewalk to serve it. The net result is a decrease in total hardcover of 518 s.f., leaving 6639 s.f. hardcover or 28.4%, all in the 0-75' zone. Discussion The proposed additional hardcover created by the two bay windows and the chimney is relatively minor, since they would comprise approximately 65 s.f. of new nardcover where plastic and rock now exists. Similarly, while the covered entryway will comprise new structural bulk to the residence, it is over existing entry deck hardcover for the most part. However, the relocation of t'.e garage doors to the east side of the garage has significant ramifications to the visual appearance of the property and to drainage patterns. Based on the proposed driveway configuration, a 30" tree which appears to be very much alive and located about 25' from the lake shore would have to be removed. Furthermore, the driveway located at this end of tha house will result in some addtional runoff concerns since that area of yard already drains to the north and east onto neighboring property. The neighbors have expressed their concern about this. Staff would suggest that applicant be required to provide a grading and drainage plan indicating how the grade will change to accomodate the garage and indicating the new drainage pattern. Regarding hardcover on the property, it appears that there are large areas of landscaped rock beds and a large play area all underlain by plastic. In staffs opinion, most of those areas could readily be revamped so that they would not constitute hardcover, and given the proximity of the lakeshore of all. of these areas, that would be an appropriate condition of approval. Additionally, the shed located 10' to 15' from the shoreline and butting up against the fence is certainly a non -conforming structure in it's location near the lake and lot line. That shed could certainly be moved to the area between the house and the fence and still maintain a 10' setback from the house and a 10' setback f rom the lot 1 i ne, while being as much as 50' or more from the lakeshore. While it is normal practice for the City in a variance resolution to advise the property owner that such structures are considered as non -conforming, in this case, the magnitude of hardcover in the 0-75' zone compels staff to suggest that the structure be removed, or at least moved to a more conforming location.
