Zoning File #1363 January 11, 1989 Pages 3 of 4 Staff has suggested to the builder that the house oltional.ly could be moved further west up to the required 10' side yard setback line, which world allow the possibility of meeting the required 75' lake setback. Due to the jug in the southeast corner of the house, it is likely the tree in question could still be saved. However, moving the house behind the 0-75' line does not appear to negate their need for grading in the 0-75' zone if a walk -out is to be constructed. The main floor of the house is already intended to be about 3' above existing grade in order to minimize the extent of the walk -out cut. In recent years the Planning Commission and City Council have taken a fairly strong stand against cuts in shoreline setback zones to create walk- outs. A case in point is the Waters' application on Casco Point, in which a walk -out cut (admittedly more severe than that proposed here) was created without proper permits and eventually was required to restore to original. grade. A second similar situation is the Waldron application on Fagerness Point, where the property owner was denied the right to cut down his yard area, in conjunction with necessary shoreline bank repairs, to create a walk -out. The difference, if any, between those requests and the current application is merely a difference in magnitude of the proposed cuts. From a drams,sage and infiltration standpoint, the walk -out cut should have on..y a minimal effect on quality or quantity of run-off water entering the lake. In the south 0-75' zone, the fill to a--commodate the revised driveway seems somewhat extensive and the proposed driveway grades are rather severe. Run-off rates may increase. The driveway apron would appear to assume a 10% slope immediately &tarting at the garage door. The whole garage access situation seems rather questionable. Based on the location of the existing and proposed structures, the average setback encroachment is reduced under the proposed plan, anal no significant existing site lines are further restricted by construction of the new house. Regarding hardcover, the numerical effects of the major increases of hardcover on the property are somewhat diminished by the relative size of the property, but the steep slopes tend to make the hardcover increases more significant than on flat lots. Overall hardcover on the property increases from 6,700 s.f. to about d,300 s.f. The amount of structural hardcover on the property is more than doubled. The increase in the 75- 250' zone from 26.51 to 39% is slightly towards the high end of what has typically been approved on Baldur Park. The total proposed hardcover, shown as a percent of the total lot area in hardcover, is prop.,4ed at 26.80, which is very typical of what has occurred on Baldur Park (see Exhibit L).
