At our last meeting with you in July, you discussed the City-wide rezoning project as part of the replacement of the Zoning Code. Tonight, we will review the use district chapters (residential, business, industrial, etc.). Attached for your review are the proposed ordinances. NEW ZONING TOOL — CONDITIONAL ADMINISTRATIVE PERMITS As we reviewed other city's codes, we discovered that some cities utilize "Administrative Permits" for various uses. They use these permits for uses or activities that do not require the level of scrutiny and discretion needed for a Conditional Use Permit determination but still require a greater level of review than a permitted use. For example, many public utility or service structures such as transmission lines, substations, and communications equipment follow very clear performance standards and are highly regulated. Staff can easily take the application and required documentation and run it through a checklist to confirm that it complies with code. It requires no subjectivity or discretion on Staff's part to make that decision. We are calling these permits "Conditional Administrative Permits." This new permit will allow a streamlined, efficient and cost-effective process for appropriate uses and activities. Importantly, the proposed approval process will still provide Staff the ability to determine that a project requires Council review. The procedures will be added to Chapter 2—Administration and Enforcement. TITLE 11 — Chapter 8 Agricultural Zoning Districts AG-1— Agricultural Preservation District We removed any reference to specific performance standards for items such as farmer's markets or home occupations. They can get lost easily in this Article of the Code, so instead they will be moved to Chapter 6 which is labeled "Performance Standards." • *New* Conditional Administrative Permits: o Communication/cellular towers o Public utility and service structures • *New* Interim uses o Farmers markets • *New* See changes to permitted and accessory uses o Commercial greenhouses o Poultry facilities • *New* Redefined rules for subdividing lots AG-2 — Agricultural District Starting in Article B, you will notice that instead of simply referencing previous code sections for the list of uses, setbacks, etc, each district is explicitly defined and described in the code for that district. This will prevent interpretation errors or authorizing some use for a district unintentionally. • *New* Conditional Administrative Permits: o Communication/cellular towers o Public utility and service structures • *New* Interim uses o Farmers markets • *New* See changes to permitted and accessory uses • *New* Redefined rules for subdividing lots TITLE 11 — Chapter 9 Residential Zoning Districts Proposed Residential Zoning Districts • R1 — Rural Residential District • R2 — Residential Estate District • R3 — Single -Family Residential o No multi -family uses allowed • R4 —Transitional Residential Zoning District. o Allows both single family lots and multi -family lots. • R5 — Medium Density Residential • R6 — High Density Residential R-2.5, Urban Renewal Residential and R-2A through R-2F have been removed. R-2.5 — Residential District This district has been removed as it was almost identical to R-3. All properties will be zoned R- 3 which will have development standards that were the least restrictive from both R-2.5 and R- 3. UR- Urban Reserve Residential This district has been removed. This zoning district was created in 1996 and no longer serves the purpose for which it was intended. It was meant to be a transitional zoning district while the area around it became eligible for development. It was a problematic district because under the Comp Plan any transitional property should be zoned UR, but that is not in the best interest of the transitional properties. Currently, there are only a couple properties zoned UR and as you can see on the map below, a portion of those properties is already zoned R-2 (UR is in gray). Staff is proposing to rezone the remaining UR to R-2. _ B1 .. 3 R-2A through R-2F Residential Districts These districts have been removed. They were created 16 years ago as part of the East Ravine Master Plan, however only one development was zoned using these designations. The reality is these districts are not used and outdated for current design and building trends. Remaining Residential Districts R-1— Rural Residential District Removed performance standards for farmer's markets and home occupations. We also removed performance standards for dog kennels; they are a conditional use and better served by an individual analysis under a conditional use permit. • *New* Conditional Administrative Permits • *New* Interim uses o Farmers markets • *New* See changes to permitted and accessory uses R-2 — Residential Estate District • *New* Conditional Administrative Permits • *New* Interim uses o Farmers markets • *New* See changes to permitted and accessory uses R-3 —Single-Family Residential District • *New* Conditional Administrative Permits • *New* Interim uses o Farmers markets • *New* See changes to permitted and accessory uses o No multi -family uses allowed • *New* Changes to development standards Il R-4 — Transitional Residential District • *New* Conditional Administrative Permits • *New* See changes to permitted and accessory uses • *New* Changes to development standards R-5 — Medium Density Residential District • *New* Conditional Administrative Permits • *New* See changes to permitted and accessory uses • *New* Changes to development standards R-6 — High Density Residential District • *New* Conditional Administrative Permits • *New* See changes to permitted and accessory uses • *New* Changes to development standards TITLE 11 — Chapter 10 Business Districts Limited Business District, B-1 The purpose of the Limited Business District is to provide a buffer district adjoining residential districts with the goal of providing an area for administrative office buildings and related office uses. Retail Business District, B-2 The purpose of the Retail Business District is to encourage retail sales and services while minimizing the impact of surrounding residential neighborhoods. General Business District, B-3 The purpose of the General Business District is to provide centralized areas for retail businesses and highway or automobile -oriented businesses. • Removed references to quasi -industrial purposes for the district. Planned Business District, P-B The purpose of the Planned Business District is to provide a mix of retail, commercial and industrial uses which are complimentary to the Cottage Grove Industrial Park. Allows for manufacturing and retail. 5 Mixed -Use Business District, M-U The purpose of the Mixed -Use Business District is to provide flexibility for complementary uses including high density residential, commercial services, retail, office and transit. Neighborhood Business District, N-B Removed, the City does not use anymore. General Changes • Removed agricultural uses from business districts. • Added car charging stations as a conditional administrative use. • Removed items that were not really uses o Examples: ■ Bike racks ■ Decorative landscape features ■ Exterior employee break area • Updated use table to reflect modern language and current market of businesses within City and those who may want to move here. o Examples: ■ Consolidated items that could be retail to general retail. Examples: • Dry goods and fabric • Casket supplies (actual use previously listed!) • Toy store ■ Consolidated list of commercial recreation uses to indoor uses versus outdoor uses • *New* Indoor uses are permitted in all districts except B-1. • *New* Outdoor uses requires a CUP. ■ Removed outdated uses. Examples: • Auction house TITLE 11 — Chapter 11 Industrial Districts Combined Limited Industry District (1-1) with General Industrial District (1-2). 1-1 was originally intended to have some non -industrial uses, however it has not developed that way and the existing uses are only industrial in nature. Combined Heavy Industrial District (1-3) with Railroad Access Industrial District (1-5). General Industrial District, I-1 (previously 1-1 and 1-2) The General Industrial District is intended to provide a district appropriate for manufacturing, compounding, processing, packaging or treatment of products, excluding any hide or animal processing, packaging, storing or transporting. Heavy Industrial District, I-2 (previously 1-3 and 1-5) The Heavy Industrial District provides areas suitable for industrial uses which are more intense than the 1-1 district and may have greater impact to noncommercial land uses. This includes uses that require direct access to rail lines for shipment. Property zoned 1-2 will be located outside the metropolitan urban service area (MUSA). Commercial Excavation District, 1-3 (previously 1-4) The Commercial Excavation District provides for the availability of sand, gravel and other mineral deposits or materials. This district seeks to permit other land uses as long as they will not conflict with adjacent land uses. General Changes • Removed items that were not really uses • Updated use table to reflect modern language and current market of businesses within City and those who may want to move here. TITLE 11 — Chapter 13 Conservancy District *New* Removed requirement that all public properties designated as parks or open space must be placed in the Conservancy District. TITLE 11 — Chapter 14 / 14A PUD Planned Unit Development District / Planned Development Overlay District • Renamed "Planned Unit Development (PUD) Overlay." • No longer designating a PUD its own zoning district. Best practices require we keep an underlying zoning district and use the PUD as an overlay. TITLE 11 — Chapter 15 Mississippi River Corridor Critical Area Overlay District No current changes. The DNR provides occasional requested updates to the regulations in this district and staff works with them to implement or request modifications as needed. CONCLUSION At the work session we will focus the discussion on a detailed review of the use lists and development standards for the residential, business and industrial districts. At the following workshop session, we will walk through the remaining zoning code chapters, focusing on performance standards, and general and special zoning provisions.

CHAPTER 13 CD CONSERVANCY DISTRICT 11-13-1: PURPOSE: The purpose of this District is to establish provisions for areas containing valuable environmental qualities which, in order to conserve the City's natural resources, preserve the amenities of its environment, prevent the overcrowding of land, avoid undue concentration of population and alleviate severe flooding problems, have been determined to best be retained in substantially an undeveloped state. 11-13-2: LANDS DESIGNATED: Private Property: Property in private ownership, consisting of 10 acres or more, that meets the requirements, may also be designated for the Conservancy District, but only upon acceptance of a petition from the property owner. 11-13-3: INTERPRETATION OF DISTRICT BOUNDARIES: When uncertainty exists as to the Conservancy District boundaries, the following rules shall apply: A. District boundaries along a stream are intended to represent the high water line of a regional flood; provided, however, that along a stream, such line shall not be less than fifty feet (50') from the center of such stream. B. District boundaries in a wetland area are intended to represent the edge of a swamp, marsh or other wetland area. The edge shall be defined as the mark delineating the highest water level which has been maintained for a sufficient period of time to leave evidence upon the landscape. The edge is commonly that point where the natural vegetation changes from predominantly aquatic to predominantly terrestrial. C. District boundaries in a public park or common open space are intended to represent the property lines of such area. 11-13-4: PETITION REQUIREMENTS: Before any property in private ownership shall be accepted for inclusion in the Conservancy District, the petitioner shall provide the following: A. A survey of the property and a legal description of the property. Such survey shall be prepared by a registered land surveyor. B. A topographic map with contour lines designated at an interval of five feet (5') or less. C. A site plan indicating the location of all trees of fifteen inches (15") in diameter or more, as well as other environmentally significant features. D.

Open space areas connected with residential, commercial and industrial planned unit developments. 5. Outdoor recreational uses operated by a governmental agency or conservation group, homeowners' or private associations and facilities for making such uses useful to the public or to associations. 11-13-6: SPECIAL USES: If, through good site and engineering designs, a development can be created which is compatible and harmonious with the natural amenities of the Conservancy District area and with surrounding land uses, a request for a special use permit for such development may be submitted. Such requests shall be accompanied by an overall plan of the entire area showing roads, parking areas, lot lines, easements, the location of tree cover, including the designation of individual trees of fifteen inches (15") in diameter or more, the location of other natural and biological features, such as wetlands and areas of valuable wildlife habitat, the locations of proposed structures, existing contours and proposed grading, drainage, utilities and landscaping in such detail as the Director of Community Development and City Engineer shall require before they may be reviewed by the Planning Commission. The approval of such a request by the City Council shall require a finding that: A. The development will not detrimentally affect or destroy natural features, such as ponds, streams, wetlands and forested areas, but will preserve and incorporate such features into the development's site design. B. The location of natural features and the site's topography have been considered in the designing and siting of all physical improvements. C. Adequate assurances have been received that the clearing of the site topsoil, trees and other natural features before the commencement of building operations will not occur. Only those areas approved for placement of physical improvements may be cleared. D. The development will not substantially reduce the natural retention storage capacity of any watercourse, thereby increasing the magnitude and column of flood at other locations. E. The soil and subsoil conditions are suitable for excavation and site preparation, and the drainage is designed to prevent erosion and environmentally deleterious surface runoff. F. The development will be free from offensive noise, vibration, smoke, dust and other particulate matter, odorous matter, fumes, water pollution and other objectionable influences. G. The petitioner will be substantially damaged by being required to place the intended development outside the CD District. 11-13-7: DEVELOPMENT STANDARDS: The following standards for development of land located within the Conservancy District are required.

Therefore, the following standards have been developed to promote, preserve and enhance the natural resources within the corridor and to protect them from adverse effects by regulating developments that would have a severe adverse and potentially irreversible impact on unique and fragile environmentally sensitive land within the Mississippi River Corridor Critical Area: A. Standards For Soil Erosion Control: Since certain areas within the corridor have steep slopes or unstable soils which may cause ecological problems due to siltation and pollution of water bodies and streams, the following standards shall be applied to all development within the corridor except certain areas designated for mining or excavation which shall comply with soil erosion standards in the Mining Ordinance: 1. No development shall be permitted on slopes of eighteen percent (18%) or more. 2. No development shall be permitted on land having a slope before alteration in excess of twelve percent (12%) but less than eighteen percent (18%), unless the applicant shall prove that the following conditions are met: a. The foundation and underlying material of any structure, including roads, shall be adequate for the slope condition and soil type. b. Adequate controls and protections exist uphill from the proposed development such that there is no danger of structures or roads being struck by falling rock, mud, uprooted trees or other materials. c. The view of the developed slope from the river and opposite river bank is consistent with the natural appearance of the undeveloped slope, consistent with any historic areas nearby, compatible with the view from historic areas and compatible with surrounding architectural features. To the maximum extent possible, the use of natural devices, including vegetation management, shall be preferred over the construction of artificial devices, including culverts, holding ponds, walls and terracing. d. All structures other than buildings and roadway surfaces, but including retaining walls, shall meet the following design requirements: (1) Retaining walls or terrace contours shall not exceed five feet (5') in height. (2) Construction shall be of native stone or wood. (3) The use of gavvions, pilings, tiebacks, metal retaining walls and precast or cast in place concrete retaining walls is specifically prohibited. (4) The minimum space between terraces and retaining walls shall be twenty feet (20'). e. Development activities shall be conducted and staged to minimize soil erosion. The smallest practical increment of land shall be developed at any one time, and that increment shall be subjected to erosion for the shortest practical period of time, not to exceed a single construction season. f. Sufficient control measures and retention facilities shall be put in place prior to commencement of each development increment to limit gross soil loss from the development site to no more than five (5) tons per acre per year during development. Gross soil loss from construction sites adjacent to streams and lakes shall not exceed two (2) tons per acre per year. g. Conditions on the site shall be stabilized within thirty (30) days following completion of the work such that the yearly gross soil loss from the site will be less than five- tenths (0.5) ton per acre. B. Standards For Development On Restrictive Soils: Certain soils in the corridor, without proper management, are unsuitable for development due to specific conditions which increase the probability of pollution of ground water, erosion or other problems detrimental to the public health, safety and welfare. Therefore, the following standards shall be applied to any development designated or identified as an area of restrictive or unsuitable soil: 1. Development of on -site waste disposal systems shall conform to the standards of the WPC-40 as interpreted by the State Pollution Control Agency and the on -site system management provision set forth in the utilities element of the Comprehensive Plan. 2.
