Single-Family Residential Lot Split Study Report INTRODUCTION May 14, 2007 In 2006, the City of Roseville was asked to consider several minor subdivision applications, including those for the Foreman, Stafne, and Mueller properties, to split existing single-family residential parcels into two or more buildable lots. These proposals generated concern from neighboring property owners as well as Planning Commission and City Council members. Due to this concern, the City Council enacted an interim ordinance prohibiting the subdivision or replatting of single-family residential lots in early January 2007, which became effective on January 30, 2007. This short-term, 90-day moratorium on single-family lot subdivisions was put into place to provide the City Council time to conduct a study on the impact of these activities on the community and to develop an appropriate course of action. The City Council convened the Single-Family Residential Lot Split Advisory Group to develop and lead a study of single-family lot split issues. The following report details the study scope, process and timeline, analytical framework, analysis and findings, and recommendations made by this group. STUDY SCOPE The scope of study the Citizens Advisory Group (CAG) developed included eight general areas of interest: ■ The appropriate dimensions (width, depth and area) of a single-family lot; ■ Whether the appropriate dimensions of a single-family lot should be a uniform standard throughout the community or should vary to reflect other single-family lots in its proximity — and any equity issues that would result from varying lot standards; ■ The appropriate shape of single-family lots (particularly the characteristics of front yard lot lines�; ■ Whether to revise or create other single-family lot standards (including, but not limited to tree preservation and replacement, open space preservation, designating steep slopes as unbuildable, etc.); ■ Whether each single-family lot created through a public action should be served by a public street or whether a private street would suffice; ■ Whether any actions resulting in an increased lot size (and decreased housing density) in some instances or areas should be balanced by subsequent actions resulting in decreased lot size (and increased housing densities) in other areas; ■ The impacts, if any, on the affordability of housing and the diversity of housing stock relative to required lot standards; and ■ How any changes to the standards or dimensions of single-family lots may relate to the Metropolitan Council's System Statement for the City of Roseville or the Roseville Imagine 2025 vision document. 2
