Second single-family house proposed on 3-acre lot with existing home
The plan adds a 4,830-square-foot single-story house with a garage to a parcel that already has a house and a shop. Because the site is in a river floodplain overlay, it needs a floodplain review, and staff are reviewing it administratively.
