History The City ofRoseville has one of the first (and oldest) shoreJand management ordinances in the State. The City saw this as a means to protect the 1I...natural ecology and aesthetic environment of the community". When adopted in 1974~ the ordinance was considered an innovative method of protecting the shoreUnes of iakes in the community from dense development too dose to the water's edge. After 1974, all single family homes with shoreline were required to be set back 75 feet from the shoreline~ the lot had to be at least 12,500 sq. ft. in size. The minimum lot width for new lots adjacent to the lake was 100 feet. In addition, business and apartments were required to have at least a 30~OOO sq. ft. lot and a minimum lot width of ISO feet. In total, the ordinance affected 299 acres of state designated lakes and 421 acres ofland surrounding the five lakes (Owasso, Josephine. Little Johanna, North Bennett~ and McCarrons). There are approximately 265 parcels abutting these Jakes. PrC)po~ed Ordinant~ The 1994 proposed ordinance expands environmental protection regulations to aU City classified lakes, wetlands, and storm ponds in addition to MnDNR classified lakes. The ordinance affects 791 acres of open water, wetland, and storm pond1ng areas and 942 acres of abutting land. There are approximately 1.608 parcels within the lakes, wetlands. and storm ponding overlay zone. Of these parcels sHghtly more than 1% (approximately 20) are currently vacant or undeveloped. The proposed ordinance attempts to protect and manage the wetlands and storm ponds that eventually contribute water, nutrients and sediment to the lakes. It regulates development around City classified lakes (Langton, Zimmerman, Bennett, Walsh, Willow, and Oasis) in the same manner as State classified lakes. In addition, it requires that new lots within 100 feet of either wetlands or storm ponds have at least 75% of the lot area above the ordinary high water level. The proposed structure must be setback 50 feet from the edge of the wetland or pond. Structures must also be setback a minimum of 30 feet from any bluff. Healthy vegetation and trees between the structure and the shorelines must be protected. Accessory structures such as gazebos and boat houses are permitted, but must take special precautions, setbacks, and landscaping to reduce their impact on shorelines and water quality. Stairways are also permitted for access over steep slopes. New deck additions. on homes built after March 27, 1974~ toward lakes, ponds and wetlands must meet the same setback as the structure. There is a "grandfather clause" for deck additions on homes built before the adoption of the original ordinance (March, 1974). Planned Unit Developments are the preferred method for any new or redeveloped project within the shoreland overlav zone. ..--~ -~----~ ~-~--~ ~ - ~----J -~---.
