Title
Mississippi River Corridor Critical Area (MRCCA) Shore Impact Zones (SIZ) [Minnesota]
Description
This data delineates the Shore Impact Zones (SIZ) of the Mississippi River Corridor Critical Area (MRCCA) as defined in Minnesota Rules, part 6106.0050, subp. 68. The MRCCA is a land corridor along the Mississippi River in the seven-county Twin Cities metro area in which special land use regulations guide development activity. The corridor extends 72 miles along the Mississippi River from the cities of Ramsey and Dayton in the north to the City of Hastings and Ravenna Township in the south. It includes 54,000 acres of land along both sides of the river. The State of Minnesota created the corridor and land use regulations in 1976. Local governments administer the regulations through their local plans and zoning ordinances. Rules regulating the MRCCA were published on December 27, 2016 and became effective January 4, 2017. The rules establish six districts, each with dimensional standards for river setbacks (among other things). The SIZ is defined as the land located between the ordinary high water level (OHWL) of public waters and a line parallel to it at a setback of 50 percent of the required structure setback. The structure setback and SIZ varies by district and river. This shapefile delineates the physical boundaries of the SIZ in the six districts., The OHWL setback and SIZ applicable to each river and district are: Mississippi River: - CA-ROS: 200 foot setback, 100 foot SIZ - CA-RN: 100 foot setback, 50 foot SIZ - CA-RTC: 75 foot setback, 37.5 foot SIZ - CA-UM: 50 foot setback, 25 foot SIZ Vermillion River: - CA-ROS: 150 foot setback, 75 foot SIZ - CA-RN: 75 foot setback, 37.5 foot SIZ - CA-SR: 75 foot setback, 37.5 foot SIZ Minnesota River: - CA-ROS: 150 foot setback, 75 foot SIZ Rum River: - CA:RN: 75 foot setback, 37.5 foot SIZ - CA-RTC: 75 foot setback, 37.5 foot SIZ Crow River: - CA-RTC: 75 foot setback, 37.5 foot SIZ This shapefile is intended to be a generalized depiction of the SIZ. Delineation of the SIZ on any parcel for development purposes must be undertaken by surveying from the OHWL. , This data is current as of January 4, 2017
