19, standards currently contained in local ordinances, statewide shoreland rules, community plans, park plans, natural resource inventory data, and existing development patterns. The DNR also considered the existing character and development pattern within each proposed district. OHWL setbacks by district. Setbacks from the OHWL vary by district: • CA-ROS: The "rural and open space" district contains the greatest concentration of native plant communities and other riparian habitat to be protected, and is the least developed of all districts. The proposed setback is 200 feet from the OHWL. This setback is the same as river setbacks for the "rural open space" district in the Interim Development Regulations in Executive Order 79-19 and is consistent with many existing local ordinances. The shore impact zone for this district is 100 feet from the OHWL. • CA -RN: The proposed setback for the "river neighborhood" district, which is primarily residential in character, is 100 feet from the OHWL, with a shore impact zone of 50 feet from the OHWL. This standard was based on river setbacks for the "urban developed" and "urban open space" districts in the Interim Development Regulations in Executive Order 79- 19. This standard is also consistent with many existing local ordinances in these areas and the standards for urban rivers in the statewide shoreland rules. • CA -RTC: The proposed setback for the "river towns and crossings" district is 75 feet from the OHWL, with a shore impact zone of 37.5 feet from the OHWL. This standard is consistent with existing development patterns and planned redevelopment within the district. The standard is also consistent with standards set in the state shoreland rules for unsewered general development and sewered recreational development waters. • CA -SR: There is no land in this district with riparian frontage on the Mississippi River and thus setbacks are governed by underlying zoning. A few properties in this district are located on a backwater of the Vermillion River, a key tributary of the Mississippi River, with a required setback of 75 feet and a shore impact zone of 37.5 feet. Setbacks from key tributaries are discussed below. • CA -UM: In districts classified as "urban mixed," which feature largely developed or redeveloping urban areas, the proposed setback is 50 feet from the OHWL, with a shore impact zone of 25 feet. This setback is consistent with the standards in the statewide shoreland rules for sewered urban rivers. • CA-UC: In the intensively -developed "urban core" district, setbacks are governed by underlying zoning. The intent is to allow these areas to develop and redevelop riverfront uses consistent with historical patterns of riverfront use. This standard was adopted to protect the character of these urban riverfronts and to respond to interest expressed by the cities of Minneapolis and Saint Paul to bring activity to the riverfront through recreational and river -oriented commercial development that improves public access to the river. Setbacks for key tributaries: Areas of confluence between key tributaries and the Mississippi River are identified as key resources in the MRCCA enabling legislation. Minn. Stat. § 116G.15, 48
