896 (5) Placement of essential services;and <br /> 897 - (6) Activities involving river-dependent commercial and industrial uses. <br /> 898 3. Application materials. Project information listed in Section 117-148(c)6(Application Materials)must be <br /> 899 submitted for all proposed developments. <br /> 900 4. Design standards. <br /> 901 a. Primary conservation areas,where they exist, must be set aside and designated as protected <br /> 902 open space in quantities meeting the following as a percentage of total parcel area: <br /> 903 (1) CA-ROS District:50%; <br /> 904 (2) CA-RN District:20%; <br /> 905 {3) CA RTC, CA UM,and CA UC Districts:10%;and <br /> 906 (4) CA-SR District: 10%if the parcel includes native plant communities or provides feasible <br /> 907 connections to a regional park or trail system,otherwise no requirement. <br /> 908 b. If the primary conservation areas exceed the amounts specified in Section 117-148(k)4a above, <br /> 909 then protection of native plant communities and natural vegetation in riparian areas shall be <br /> 910 prioritized. <br /> 911 c. If primary conservation areas exist but do not have natural vegetation(identified as restoration <br /> 912 priorities in the MRCCA Plan),then a vegetation assessment must be completed to evaluate the <br /> 913 unvegetated primary conservation areas and determine whether vegetation restoration is <br /> 914 needed. If restoration is needed,vegetation must be restored according to Section 117-148(i)6b <br /> 915 (under Vegetation restoration plan). <br /> 916 d. If primary conservation areas do not exist on the parcel and portions of the parcel have been <br /> 917 identified in the MRCCA plan as a restoration area,vegetation must be restored in the identified <br /> 918 areas according to Section 117-148(i)6b(under Vegetation restoration plan)and the area must <br /> 919 be set aside and designated as protected open space. <br /> 920 e. Storm water treatment areas or other green infrastructure may be used to meet the protected <br /> 921 open space requirements if the vegetation provides biological and ecological functions. <br /> 922 f. Land dedicated under this Section for public river access, parks,or other open space or public <br /> 923 facilities may be counted toward the protected open space requirement. <br /> 924 g. Protected open space areas must connect open space, natural areas,and recreational areas, <br /> 925 where present on adjacent parcels,as much as possible to form an interconnected network. <br /> 926 5. Permanent protection of designated open space. <br /> 927 a. Designated open space areas must be protected through one or more of the following methods: <br /> 928 (1) Public acquisition by a government entity for conservation purposes; <br /> 929 (2) A permanent conservation easement,as provided in Minnesota Statutes,chapter 84C; <br /> 930 (3) A deed restriction;and <br /> 931 (4) Other arrangements that achieve an equivalent degree of protection. <br /> 932 b. Permanent protection methods must ensure the long-term management of vegetation to meet <br /> 933 its biological and ecological functions, prohibit structures,and prohibit land alteration,except as <br /> 934 needed to provide public recreational facilities and access to the river. <br /> 26 <br />
