1 a. To protect and enhance the natural and scenic values of the MRCCA during development 2 or redevelopment of the remaining large sites; 3 b. To establish standards for protecting and restoring biological and ecological functions of 4 primary conservation areas on large sites; and 5 c. To encourage restoration of natural vegetation during development or redevelopment of 6 large sites where restoration opportunities have been identified in MRCCA plans. 7 (2) Applicability. 8 a. The design standards in this section apply to subdivisions, planned unit developments 9 and master -planned development and redevelopment of land involving ten or more acres 10 for contiguous parcels that abut the Mississippi River and 20 or more acres for all other 11 parcels, including smaller individual sites within the following developments that are 12 part of a common plan of development that may be constructed at different times: 13 1. Subdivisions; 14 2. Planned unit developments; and 15 3. Master -planned development and redevelopment of land. 16 b. The following activities are exempt from the requirements of this section: 17 1. Minor subdivisions consisting of three or fewer lots; 18 2. Minor boundary line corrections; 19 3. Resolutions of encroachments; 20 4. Additions to existing lots of record; 21 5. Placement of essential services; and 22 6. Activities involving river -dependent commercial and industrial uses. 23 (4) Design standards. 24 a. Primary conservation areas, where they exist, must be set aside and designated as 25 protected open space in quantities meeting the following as a percentage of total parcel 26 area: 27 1. CA-ROS District: 50 percent; 28 2. CA -RN District: 20 percent; 29 3. CA -SR District: Ten percent if the parcel includes native plant communities or 30 provides feasible connections to a regional park or trail system, otherwise no 31 requirement. 32 b. If the primary conservation areas exceed the amounts specified in section 920(K)(4)a 33 above, then protection of native plant communities and natural vegetation in riparian 34 areas shall be prioritized. 35 c. If primary conservation areas exist but do not have natural vegetation (identified as 36 restoration priorities in the MRCCA plan), then a vegetation assessment must be 37 completed to evaluate the unvegetated primary conservation areas and determine 38 whether vegetation restoration is needed. 39 d. If primary conservation areas do not exist on the parcel and portions of the parcel have 40 been identified in the MRCCA plan as a restoration area, vegetation must be restored in 41 the identified areas and the area must be set aside and designated as protected open space. 42 e. Stoll water treatment areas or other green infrastructure may be used to meet the 43 protected open space requirements if the vegetation provides biological and ecological 44 functions. 45 f. Land dedicated under this section for public river access, parks, or other open space, or 46 public facilities may be counted toward the protected open space requirement. 47 g. Protected open space areas must connect open space, natural areas, and recreational 48 areas, where present on adjacent parcels, as much as possible, to form an interconnected 49 network. 50 (5) Permanent protection of designated open space. 51 a. Designated open space areas must be protected through one or more of the following 52 methods: Attachment A — Ordinance #23-14 Page 101 of 141
