Section 30-253: Landscaping Requirements Landscaping shall be provided based on the following requirements for building foundations, paved areas, street frontages, yards, and bufferyards. (A) Building Foundations. (1) For every 100 linear feet of building foundation, the landscaping installed shall at a minimum meet the number of landscaping points specified in Figure 30- 253d. (2) Tall trees shall not be used to meet building foundation landscaping requirements. (3) Building foundation landscaping shall be placed so that at maturity, the plant’s drip line is located within 10 feet of the building foundation. (4) Building expansions shall be subject to the same landscaping formula requirements as new buildings (see Figure 30-253d). The formula shall not be applied to portions of the building foundation developed prior to the adoption of this ordinance. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 4 Municipal Codes (5) The measurement of the building foundation may be simplified as the smallest single rectangle that contains the entire building perimeter, except that the sides of the building facing an adjacent public street, where the actual perimeter shall be measured. (B) Paved Areas. (1) For every 10 off-street parking stalls or 10,000 square feet of pavement (whichever yields the greater landscaping requirement), landscaping shall at a minimum meet the number of landscaping points specified in Figure 30-253d. (2) Paved area landscaping shall be placed so that at maturity, the plant’s drip line is located within 10 feet of the paved area. Said area does not have to be provided in one contiguous area. Plants used to fulfill this requirement shall visually screen parking, loading, and circulation areas from view from public streets.

Internal parking lot landscaping shall be accomplished by the installation of landscaped planter islands or other types of landscaping application approved by the Director of Community Development, or designee. (b) Landscaped planter islands shall be required at the ends of all parking rows, driveway entrances, and at intermediate locations such that there is a maximum of 180 feet between islands. See Figure 30-253a. (i) Landscaped planter islands are required where 2 rows of parking stalls meet at a right angle. See Figure 30-253b. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 5 Municipal Codes Figure 30-253a: Requirements for Islands Figure 30-253b: Parking Rows at Right Angles City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 6 Municipal Codes (c) Each landscaped planter island shall be no less than 125 square feet in area and 7 feet in width, measured from the back of the curb. For double-parking rows, each landscaped planter island shall be no less than 250 square feet in area. The 7-foot width requirement may be reduced to accommodate the triangular shape resulting from angled parking. (i) Exception. A continuous 7-foot wide landscape strip may be provided between double parking rows in place of landscaped planter islands. (ii) See Figure 30-253c. Figure 30-253c: Interior Landscaping (d) All islands shall be crowned for positive drainage, unless bio-retention methods of stormwater management are utilized per a stormwater management plan approved by the Department of Public Works. (e) One shade tree or tall deciduous tree shall be provided for every island and for every 40 linear feet of continuous landscape strip. Medium or low trees (evergreen or deciduous) may be used to supplement deciduous City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 7 Municipal Codes shade trees in locations that may not support healthy shade tree or tall deciduous tree growth. This determination shall be made by the Director of Community Development, or designee. For double-row parking, 2 medium trees or 1 tall deciduous tree shall be required for each island. [Revised 6.11.19] (i) Trees shall be a minimum of 2 inches in caliper and not less than 6 feet tall at planting. (ii) Shrubs shall be a minimum of 18 inches at planting. (f) In addition to the required trees and shrubs, islands shall be planted with grass, low ground cover, shrubs, flowers, decorative stone/river rock, mulch, or a combination thereof. Mulches and decorative stone shall be installed so that the loose material will not erode, fall, be plowed, or be otherwise transported onto paved surfaces. (g) To ensure proper visibility within the parking lot, shrubs shall be no higher than 2 feet and the branches of trees shall start no less than 6 feet from the ground, unless located in areas that do not affect driver visibility. (5) Parking lot screening required by Section 30-175(I) shall count toward the landscaping requirements of this Section. (6) Paved area expansions shall be subject to the same landscaping formula requirements as new paved areas (see Figure 30-253d). The formula shall not be applied to paved areas developed prior to the adoption of this ordinance. (C) Street Frontages. (1) For every 100 linear feet of street frontage of a developed lot abutting a public street right-of-way, the landscaping installed shall at a minimum meet the number of landscaping points specified in Figure 30-253d. (2) Street frontage landscaping shall be placed so that at maturity, the plant’s drip line is located within 10 feet of the public street right-of-way. (3) Landscaping shall not located within a public right-of-way. Landscaping shall not impede vehicle or pedestrian visibility. See Section 30-174. (4) A minimum of 50 percent of all points shall be devoted to decorative or medium trees, or a combination of such trees. (5) In the case of any new principal building, building expansion, new paved area, or paved area expansion on a previously-developed site, a percentage of the landscaping points specified in Figure 30-253d shall be required. For new City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 8 Municipal Codes paved areas and expansions, the required percentage shall be equal to the percentage of the paved area expansion as compared to the existing paved area square footage. For new buildings and expansions, the required percentage shall be the percentage of the building expansion as compared to the existing building square footage. (D) Yards. (1) For every 1,000 square feet of gross floor area of all principal and accessory buildings on the site, the landscaping installed shall at a minimum meet the number of landscaping points specified in Figure 30-253d. (2) Landscaping required by this Section is most effective if located away from other areas required for landscaping such as building foundations, street frontages, paved areas, protected green space areas, or bufferyards. (3) The intent of this Section is to provide yard shade and to require a visual screen of a minimum of 6 feet in height for all detached exterior appurtenances (such as HVAC, utility boxes, standpipes, stormwater discharge pipes and other pipes). (4) Building expansions shall be subject to the same landscaping formula requirements as new buildings (see Figure 30-253d). The formula shall not be applied to portions of buildings developed prior to the adoption of this ordinance. (E) Bufferyards. A bufferyard is a combination of distance and a visual buffer or barrier. It includes an area, together with the combination of plantings, berms and fencing that are required to eliminate or reduce existing or potential nuisances (e.g. dirt, litter, noise, glare, signs, and incompatible land uses, buildings, or parking areas). (1) The required level of bufferyard opacity is listed in Figure 30-253e. Detailed bufferyard requirements are listed in Figure 30-253f. Opacity is a quantitatively-derived measure which indicates the degree to which a particular bufferyard screens the abutting property. The required level of opacity indicated is directly related to the degree to which the potential character of development differs between different zoning districts. (2) Bufferyards shall be located along (and within) the outer perimeter of a lot wherever 2 different zoning districts abut one another. Bufferyards shall not be required in front yards or along public street frontages. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 9 Municipal Codes (3) To ensure that the year-round screening objectives are fulfilled, only the plant classifications in Figure 30-254b listed as “Appropriate for Screening” shall count toward bufferyard point totals, unless non-screening plants are used in combination with a solid fence or a berm of 6 feet or more, in accordance with Figure 30-253f. (4) Reduction of Required Bufferyard Width. (a) Intent. This Subsection is intended to allow for the reduction of the required width of a required bufferyard where the presence of permanently protected green space or similar areas provides equivalent permanent screening and separation benefits as would be provided by the otherwise required bufferyard. (b) Where the minimum permitted width for the required bufferyard is not available under the current or proposed state of development, the Director of Community Development, or designee, may reduce the width required for the bufferyard to that currently available on the site, provided that the portion of the site that requires a bufferyard contains 1 or more of the following: (i) Steep slopes that contain retaining walls or rip-rap (ii) Permanently undevelopable green space or other permanently protected green space designated on site plans such as a native or restored prairies or park savannas, wetlands, bodies of water, floodplains, drainageways, upland woods, stormwater basins, or other natural resource protection areas, including areas protected by covenants or conversation easements. (c) If there is permanently protected green space located on an adjoining property adjacent to the portion of a site that requires a bufferyard, the Director of Community Development, or designee, may reduce the width required for the bufferyard. The reduction shall consist of no more than 1 foot for every 3 feet of permanently protected green space on the adjoining property, as measured from the property line at a right angle into said adjacent property. There shall be no reduction in the number of landscape points required. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 10 Municipal Codes (5) Use of Required Bufferyard and Landscaped Areas. (a) Any and all required bufferyards or landscaped areas may be used for passive recreation activities. Said areas may contain pedestrian or bike trails provided that no required landscaping material is eliminated; the total width of the required bufferyard, or the total area of required landscaping, is maintained; and all other regulations of this Chapter are met. (b) No swimming pools, tennis courts, sports fields, golf courses, or other such similar active recreational uses shall be permitted. (c) No parking, buildings, outdoor light fixtures, and no outdoor display of storage of materials shall be permitted. (d) Paving in such areas shall be limited to that required for necessary access to or across the subject property or for a passive recreational use such as paved multiuse trails or pedestrian walkways. (F) Determination of Landscaping Requirements. (1) The requirements of this Article are additive to each other and any other landscaping or screening requirements in this Chapter. (2) Landscape points used to meet one requirement (e.g. building foundations, paved areas, street frontages, yards, or bufferyards) shall not be used to meet another requirement. (G) Measurement and Calculation. (1) Landscaping point values shall be doubled for mature existing landscape plantings that are retained and protected with the development of the site. Existing plantings eligible for double point values shall be determined by the City Forester. (2) In calculating the number of required landscaping points under the provisions of this Section, all areas and distances on which required calculations are based shall be rounded up to the nearest whole number of square feet or linear feet. (3) Any partial plant derived from the required calculations of this Section (for example: 23.3 shade trees) shall be rounded up to the next whole plant (for example: 24 shade trees). City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 11 Municipal Codes (H) Utility Easements. Landscaping materials, fences and berms located within a duly recorded utility, stormwater, or a pedestrian easement shall not count toward meeting a landscaping requirement, unless authorized otherwise by the City and the easement holder. However, the width of such areas may be counted as part of a landscaping width requirement for bufferyards. (I) Other Green Space Areas. Green space areas not used for landscape plantings other than natural resource protection areas shall be graded and seeded or sodded with an acceptable maintainable seed mix, restored to native vegetation. Alternatively, such areas may be maintained in crop production if a principal use exists on-site and if approved by the Director of Community Development, or designee.

For example, if a landscaping plan includes a total of 20 Tall Deciduous Trees, no more than 1 of those 20 trees may be classified as a “Species to Use Sparingly.” The purpose of this provision is to encourage plant species diversity throughout the City. 2 “Prohibited Species” shall not be included as part of any landscaping plan that is subject to City review per Section 30-252. The purpose of this provision is to limit the planting of species that are invasive, have invasive tendencies, or that may perpetuate or spread disease. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 27 Municipal Codes Section 30-255: Standards for Rain Gardens and Bioswales (A) Definition. (1) Rain gardens can serve both as landscaping and stormwater management features on a building site, where appropriately designed and sited. A rain garden is a shallow, depressed garden that is designed and positioned on a site to capture stormwater runoff and allow for the infiltration of water back into the ground. Rain garden plants are carefully chosen for their ability to withstand moisture extremes and potentially high concentrations of nutrients and sediments that are often found in stormwater runoff. A well designed and maintained rain garden serves as an attractive component of an overall landscaping plan for a development site. (2) Bioswales can serve both as landscaping and stormwater management features on a building site, where appropriately designed and sited. A bioswale is a linear, vegetative stormwater runoff conveyance system that is designed to store and infiltrate water from small storm events back into the ground and direct water from heavy rain events to appropriate storm sewer inlets or other management facilities. The flow of water being conveyed through a bioswale is slowed down, allowing for municipal storm systems to more effectively manage heavier rain events and help reduce the risk of flooding on or off-site. Water being infiltrated or conveyed via a bioswale is also filtered by the vegetation within it, generally improving both ground and surface water quality. (B) Requirements. (1) The installation of a rain garden or bioswale may contribute to the overall stormwater management plan for a development site and count toward meeting the City’s landscaping guidelines. Rain gardens and bioswales may count for 20 points for every 20 square feet for yard, building foundation, and/or paved area requirements, provided the following requirements are met. Rain gardens and bioswales shall count for no more than 100 points of the required landscaping per site. (2) Detailed plans shall be provided that show all proposed dimensions of the rain garden or bioswale including length, width, depth, and slope of depression; location of the rain garden or bioswale on the lot relative to hard-surfaced areas, downspouts, and site topography; characteristics of the soil underlying the rain garden or bioswale; description of planting media; the species, number, and size at time of installation of all vegetation proposed for the rain City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 28 Municipal Codes garden or bioswale; and information on any other materials that will be used to line the rain garden or bioswale. (3) Installation shall not be proposed for any of the following areas of a site: (a) Areas where there is known soil contamination unless the rain garden or bioswale is proposed to be constructed with an under-drain; (b) Areas where the characteristics of the soil would not allow for the proper infiltration of water into the ground; or (c) Areas where there are expected to be high levels of foot traffic, unless such areas are protected from foot traffic. (4) The owner of the site shall demonstrate that the rain garden or bioswale is properly maintained, specifically: kept free of trash, weeds, debris, and dead or dying plants; any pipes associated with the rain garden or bioswale will be inspected on an annual basis and kept free of debris; and by the beginning of every spring dead plant materials will be cut back or removed. (5) Bioswales and rain gardens shall be generously (and appropriately) vegetated to qualify for landscaping points. If bioswales and rain gardens (or portions thereof) are lined with turf but do not include other vegetation, then they will not count toward meeting landscaping point requirements. (6) Rain gardens and bioswales may serve as a component of an overall stormwater management plan for a site only if detailed plans, calculations, and specifications are submitted and approved by the Department of Public Works. Detailed plans shall include the location and description of all other stormwater management facilities serving the site, particularly those to which any bioswale will be directed. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 29 Municipal Codes Section 30-256: Installation Requirements (A) Installation. Any and all landscaping and bufferyard material required by the provisions of this Chapter shall be installed on the subject property, in accordance with the approved site plan within 365 days of the issuance of an occupancy permit for any building on the subject property. (B) If existing plant material meets the requirements of this Article and will be preserved on the subject property following the completion of development, it may be counted as contributing to the landscaping requirements and worth double the landscaping point value per plant. (C) All landscaping and bufferyard areas shall be seeded with lawn or native ground cover unless such vegetation is already fully established. (D) The exact placement of plants and structures shall be depicted on the required detailed landscaping plan submitted to the City for its approval. Such plant and structure location shall be the decision of each property owner provided the following requirements are met: (1) Evergreen shrubs shall be planted in clusters to maximize their chance for survival. (2) Where a combination of plant materials, berming, and fencing is used in a bufferyard, the fence and/or berm may be located toward the interior or exterior of the subject property and at least 50 percent of the required landscaping points shall be located toward the exterior of the subject property. (3) A property owner may establish through a written agreement, recorded with the Register of Deeds that an abutting property owner agrees to provide on the immediately abutting portion of his or her land a partial or full portion of the required bufferyard, thereby relieving the developer of the responsibility of providing the entire bufferyard on his property. Responsibility for maintenance of bufferyard landscaping shall be included as part of this agreement. (4) Under no circumstance shall landscaping or bufferyard materials be selected or located in a manner resulting in the creation of a safety or visibility hazard. (5) The restrictions on types of plants listed in this Article shall apply. (E) Upon completion of the approved landscape improvements, a certification of compliance shall also be submitted by the owner or agent. City of Oshkosh Zoning Ordinance Municipal Code City of Oshkosh Chapter 30 – Article IX - Page 30 Municipal Codes (F) Maintenance. (1) The continual maintenance of all required landscaping and bufferyard materials shall be a requirement of this Chapter and shall be the responsibility of the owner of the property on which said materials and plants are required. This requirement shall run with the property and shall be binding upon all future property owners. Development of any or all property following the effective date of this Chapter shall constitute an agreement by the property owner to comply with the provisions of this Section. (2) The owner of the premises shall be responsible for the watering, maintenance, repair, and replacement of all landscaping, fences, and other landscape architectural features on the site. All planting beds shall be kept weed-free. Plant material which has died shall be replaced with equivalent vegetation within twelve months.
