#2166 - Janet Kieman August 14,1996 Page 5 The existii.;; house contains three bedrooms on the second floor not including the sleeping porch, one bedroom on the main floor (called a study/bedroom but has closet and bath) and there is a room in the basement that is defined as rec room but has a closet, and therefore would be considered a bedroom for septic system design purposes. However, applicant notes that this room has not and likely would not be used as a bedroom. The proposed house suggests no changes to that basement room, has a guest bedroom on the main floor and three bedrooms on the second floor, i.e. resulting in the same bedroom situation as currently exists. It appears, then, that there is no increase in the number of bedrooms with this addition. It is unknown whether the existing septic system is sized adequately to serve the existing and proposed residence. While it may be feasible to add one additional drainfield line on the downhill side of the existing trenches, (no testing work has been done to confirm this), the existing system has not exhibited any signs of failure and with sewer pending, it may be unnecessary to add to the system unless a failure occurs under the usage of this new owner. It should be noted for the record that the previous owners' family size may have not taxed the system to its limit. The difference between this situation and that on Long Lake Blvd. which the Planning Commission struggled with, is that technically there are no additional bedrooms in this proposal. However, some of the same risks are borne by this property owner in that if the system fails and sewer does not become available, only a limited degree of system expansion is possible before a holding tank would be a final option. Bluff Not an Issue Staff has confirmed that the locations on the site where construction is proposed do not constitute a bluff, although the next property to the north may in fact be subject to the bluff impact zone protective requirements. Drainage Drainage from this property appears to all flow to the southwest comer of the property south of the garage. This will not change under the new site plan, but this area will also now be taken up by the relocated driveway. This may force more runoff onto the adjacent property or into the neighbor's unique serpentine wall, pplicant should be required to provide a garding and drainage plan for the site showing how mnott will be addressed under the new site plan.
