� O� O , O CITY of ORONO �.- � � �i�.-�' �► RESOLUTION OF THE CITY COUNCIL �� G,�`� No. 6 � � � �kESH04 h. Applicant proposes to install a series of raingardens southeast of the residence to help mitigate the excess hardcover. Westerly portions of the roof will be provided with gutters and downspouts to direct runoff to the raingardens. A vegetated swale paralleling the lakeshore is also proposed which will filter runoff from the site as well as runoff discharge from the City storm sewer along the eastern boundary of the site. i. The existing average lakeshore setback line runs through the streetward half of the existing house, and will run through the midpoint of the proposed house. Views of the lake enjoyed by the neighboring home to the west will be slightly increased. Views of the lake enjoyed by the home to the east will be slightly decreased (from side windows only). There is very minimal impact from the average setback encroachment. j. Slope percentage decreases from west to east across the Property. The neighboring property to the west has slopes in excess of 30% and meets the definition of bluff, but only the northwesterly portion of Applicant"s Property is a bluff, with the 970' contour line defining the top of bluff. While the existing house is partly within the defined bluff, a majority of the proposed structure is not within the defined bluff, but the attached garage will be within the bluff impact zone. The proposed grading and drainage plan including swales, roof rain gutters, rain gardens and other features will minimize impact to adjacent properties and will enhance slope stability. k. Because the proposed site grading plan will involve more than 10 cubic yards of earth movement, a conditional use permit and variance are required per Section 78-1286. The grading plan involves excavating for the new house foundation; excavating lakeward of the house to create a walkout situation; grading swales alongside of the house and garage; and filling streetward of the house to establish a grade for the driveway. Additional grading will be required to create the proposed raingardens. Erosion control during construction will also be critical as the Property naturally drains toward the property to the west. The proposed grading plan directs a majority of the driveway drainage to the east side of the house. 1. Two of the three large oak trees in the 0-75' zone are proposed to be removed, including the 22" oak alongside the existing house (on the neighboring property) and the 34" oak just south of the existing house. The Applicant's landscaping consultant has recommended these be removed as a pre-emptive Page 4 of 8
