Table 1: Dimensional Standards <br />CA -RN <br />CA -RTC <br />- <br />CA -SR <br />CA-UC <br />Height <br />35' <br />35' <br />48'* <br />Underlying <br />zoning <br />65 * <br />Underlying <br />zoning <br />River Setback <br />200' <br />100' <br />75' <br />NA <br />50' <br />Underlying <br />zoning <br />Bluff Setback <br />100' <br />40' <br />40' <br />40' <br />40' <br />40' <br />*Greater height may be allowed with a local Conditional Use Permit. <br />All MRCCA standards are administered through local zoning ordinances. Local dimensional standards may <br />differ from those identified above. <br />Expansion of Nonconforming Structures (part 6106.0080, Subp. 3) <br />Legal nonconforming structures are structures that were lawfully permitted when they were built. However, <br />when zoning standards change, these lawfully established structures that do not conform to the new <br />standards become legally nonconforming or "grandfathered." The 2016 rules clarify that local governments <br />may allow the lateral expansion of legally nonconforming principal structures, as long as they do not expand <br />further into required setbacks from the bluffline and from the river. <br />Vegetation & Land Alteration Standards (part 6106.0150) <br />Vegetation stabilizes soil and helps to slow, absorb, and filter stormwater before it runs into the river. Land <br />alteration in areas near water and on steep slopes increases the risk of soil erosion and the movement of <br />sediment into water. Retaining and/or restoring deep-rooted vegetation along the river's edge and on steep <br />slopes, and preventing erosion during development, are important strategies for protecting water quality, as <br />well as the unique natural character and animal habitat along the corridor. <br />Vegetation and land alteration standards in the 2016 rules do not vary by district, but will affect your <br />property if you plan any future changes to your property. <br />Permit Requirements for Vegetation Removal and Land Alteration <br />Under the 2016 rules, homeowners now need to obtain a permit from the local government for intensive <br />vegetation clearing and some land alteration activities in sensitive areas (primarily along the river's edge and <br />on bluffs) that exceed certain thresholds. The purpose of requiring a permit is to connect property owners <br />with a qualified person who can guide these activities to minimize negative impacts to water quality, slope <br />stability, and habitat. <br />Minnesota DNR — Division of Ecological & Water Resources April 2016 <br />
