This is a design for parcel 22003-34-00030 which will be located on parcel #22003-34-90200. There is an existing three bedroom 2200 square foot residence and 624 square foot garage. The garage and residence are going to be demolished and two two bedroom residences will replace the former structures. The existing residence is served by a Glendon on-site system installed under SWG2008-00253 on parcel #22003-34-90200. This will serve one of the proposed new residence and the second residence will be served by a two bedroom Oscar on-site system. There is a cabin on 22003-34-00160 which will be demolished and replaced with a two bedroom residence. This residence will be served by an existing two bedroom permitted in 1977. There will be a new 1200 gallon septic tank and a 1' ,o gallon pump tank that will pump over to the existing septic system. I am submitting a design for the Oscar for parcel #22003-34-00030 located on parcel #22003- 34-90200. The reserve will be located on 22003-34-00160.1 have dug holes on this parcel. This will accommodate two reserve drainfields, one for 22003-34-00160 and one for 22003-34- 00030. This project is owned by three sisters. They are in final stages of getting t .e well a roved a Group B water system. 17 0 I will get declaration recordings after your review.
