4. Lots created by an approved division of an R-l platted lot can be no smaller than the average lot size of all contiguous lots (those sharing a common boundmy with the original lot) and no smaller than the current standard lot size of 11,000 sf For example, John and Mary Doe have a 45,000 sflot. T71e three continuous lots (right, left, and rear) are 20,000, 12,000, and 30,000 square feet respectively with an average of20, 666 sf John and Mmy may divide their lot, but they may only divide it into two lots because the remaining 24,334 sflot cannot be made smaller. Community Development staff has reviewed these recommendations and has discussed them with the City's attorney. The following narrative is an analysis of each ofthese recommendations. 1. Declare all single-family lots legal on a set date The City ofRoseville fIrst enacted a zoning ordinance on May 21, 1959, with regulations that required lots zoned R-l Single-Family Residential to have 11,000 square feet in area, an 85- foot width, and lID-foot depth. Many lots platted prior to this date did not meet the requirements set forward by this code, which made them all nonconforming, pre-existing lots. The Zarling Code does not callout or have regulation on nonconforming, pre-existing lots; however, there are implicit regulations for non-conforming, pre-existing single-family residential lots within Section 1012 General Requirements. Section 1012.0I(B) states: "a platted lot or parcel ofland of record on May 21, 1959, which does not meet the requirements of this Code as to area, width or open space may be utilized for single-family residential dwelling purposes provided the measurements of such area, width or open space are within seventy percent of the requirements of this code." Essentially, this section grants "legal nonconfonnity" to these pre-May 1959 lots, allowing a house to be built on them as long as they are within seventy percent oflot miuimums, which is 7,700 square feet in area, 59.5 feet in width, and 77 feet in depth. The Single-Family Residential Lot Split Advisory Group spent siguificant time discussing the issue of pre- and post-May 1959 lots. Ultimately the group recommended to the City Council that instead of this quasi overlay district that currently exists in the Code for pre-May 1959 lots that the Council considers creating both a small lot zoning district and an overlay zoning district. The zoning district would allow for consolidation or simplifIcation of subdivision standards while the overlay zoning district would maintain the legally non-conforming status of the pre-May 1959 lots. In the staff analysis of this recommendation, the proposal to declare all single-family lots legal on a set date seems an unconventional zoning practice. In Roseville, there are several areas where platted lots are quite narrow (25 feet wide). These are legally platted lots where the owners have purchased one or more lot to create a buildable parcel without replatting these parcels. Section IOI2.0I(e) states: .
