Zoning File #1745 June 10, 1992 Page 3 Description of Request la: The applicant proposes major alterations of existing cabin I consisting of an attic expansion for storage purposes, new siding and windows and alterations/remodeling of interior layout. Review Exhibit H and I, the existing deck on the south side will remain as shown at 8' x 22*. Applicant will reinstall a new overhang over the existing grade level patio measuring approximately 7' x 17' to the west side. Note overhang is now part of the gabled roof design and has been relocated slightly to the south so that it no longer blocks view windows along west side of structure. Review Exhibit I, the new additions to the cottage consist of grade level deck and proposed screened porch. 250.6 s.f. of the grade level deck is located within the 0-75' setback area and 630.52 s.f. of the improvement is located within the 75-250' setback area. 'a V - J. f-K-- Variances are required for all improvements to structure located within 0-75' setback area and for portion of grade level deck also located within 0-75' setback area. Per Gaffron's memo variances will also be required for treatment of grey—water from existing single sink in kitchen area of dwelling. There is no way that an on-site septic system can be developed within the limited area within the 75-250' setback area. The only option available to applicant if sink is to remain is to approve a variance for the use of a holding tank. Review Exhibit E, note the specific conditions set forth for any use of a holding tank on a Big Island property. As Gaffron's memo also notes, there has not been a request for a holding tank on Big Island since the 1978 septic codes were adopted. It is the practice of the City whenever a property owner seeks approval for the use of a holding tank that Council approval is required. There are several physical limitations that will create problems for the installation of a holding tank on this property and if approved will require special design features. The RS district requires foundations, at permanent frost depth, solid masonry or treated wood foundation that completely encloses the entire perimeter of the building. Staff has no knowledge as to the type of foundation that exists today. Review Exhibit N. The Assessor's record notes cabin was constructed in 1963 with footings only. There is no record of any additional improvements to the foundation since 1963. Applicant has been asked to arrange for an inspection by the Building Inspector, hopefully, prior to our meeting of Monday evening, so that they can report on the status of the current foundation and what applicant will be expected to provide. If structure is to be raised and a new foundation installed, applicant may be asked to move structure within the limited building envelope within the 75-250' setback area. (Review Exhibit J.)
