Reconstruction or replacement of a lawfully existing use or structure following a casualty loss.

Remodeling, rehabilitation or improvements to existing uses or structures which do not substantially change the location of structures, parking or other site improvements.

Additions or enlargements of existing uses or structures which increase floor area or impervious coverage area by less than 20%. Where such additions or enlargements are 20% or greater, these provisions shall apply only to that portion where the new development occurs.

Administration and enforcement.

Landscaping plan review required.

Submittal for landscaping plan approval. Submittal shall include the following information:

Official List of Recommended and Prohibited Plant Materials. Plantings shall be used in any required landscaped areas or buffer yards consistent with the City of Papillion Landscaping Standards, provided through the Planning Department. All plant materials shall conform in size, species and spacing with this section of the chapter.

Use of inorganic landscaping materials. No artificial trees, shrubs, plants or turf shall be used to fulfill the minimum requirements for landscaping. Inorganic materials, such as stone or decorative pavers, may be used, provided that such material does not comprise more than 35% of the minimum required landscaped area. Other concrete and/or asphalt pavement surfaces such as walkways and driveways may be located within the minimum required landscaped area, provided that the landscaping required within such area is installed on another portion of the same lot.

Supplements to the recommended list of plant materials. The Recommended List of Plant Materials has been compiled using the latest research data available. Plants other than those listed may be used to fulfill minimum landscaping requirements as approved by the Planning Director. To be considered for approval, a proposed plant material must be submitted for review with the following information:

Encouragement of native landscaping materials. The use of suitable native plant materials is encouraged to fulfill landscaping requirements. Native plants, or those plants which occur naturally in this region, have shown greater adaptability to the seasonal and climate changes which occur in this region.

Installation standards.

Minimum spacing of plant materials shall be as follows:

Supplemental installation requirements for shrubs.

The guaranty shall be submitted in a form approved by the Chief Building Official or designee. The guaranty shall be in writing and shall identify the amount of the guaranty, the required terms, and the permitted time allowed for the installation of the required landscaping or screening improvement. The guaranty shall expire in no less than 18 months from the date of its issuance or as otherwise required by the Chief Building Official or designee.

The permitted time allowed for said installation shall be limited to one year after occupancy, the issuance of a certificate of occupancy, the issuance of a certificate of zoning compliance, or the commencement of operations, whichever comes first; however, this time period may be extended by the City Council upon written recommendation by the Chief Building Official or designee.

In the event the required landscaping or screening improvement is not installed by the expiration of the permitted time, the developer or owner of the land at issue shall grant the City of Papillion permission to enter upon the land to install the required landscaping or screening, and the City shall retain the corresponding guaranty.

The buffer yard dimensions set forth in this section apply to zoning districts which share a common lot line or are adjacent but separated by an intervening street or alley.

When a street or alley separates adjacent zoning districts requiring a buffer yard, the size of the buffer yard shall be 1/2 the required buffer yard set forth in this section. No buffer yard is required where the separating street right-of-way exceeds 75 feet in width.

Each required buffer yard must be entirely landscaped and free of paved areas, accessways, storage or other disturbances.

Application. Screening is required between adjacent zoning districts indicated in the buffer yard requirements when one or more of the following conditions in the more intensive zoning district is directly visible from and faces either the boundary of the less intensive zoning district or a public right-of-way:

Screen design. A screen of at least six feet in height, including walls, fences, berming, or landscaping shall be provided that prevents direct visibility of the conditions listed in this section from less intensive uses or public streets. The screen may include the following:

Screening shall not adversely affect surface water drainage.

The finished side of any fence or wall providing screening shall always be oriented toward the public street or adjacent property.

Screening may be interrupted to provide access drives to service areas or for loading purposes to buildings. Such breaks or interruptions shall not exceed 20% of the length of the required screened area.

Parking lot peripheral landscaping is required for all parking facilities. Parking lot peripheral landscaping is defined as the continuous landscaped area(s) at the physical edge around the parking facility.

Each parking structure shall be considered a structure and subject to the setback and landscaping requirements for its respective zoning district.

Parking facilities may not be located in a buffer yard required by § 205-231. If no buffer yard is required, each parking facility that abuts a residential use without an intervening street or alley shall provide a ten-foot landscaped buffer along its common property line with the residential use.

Parking facility screening. Any nonresidential parking facility that abuts property in a residential district shall provide a screen compliant with the provisions of § 205-232B for the length of the common boundary. A grade change, terrace, or other site or design feature which blocks the sight line of headlights into a residential property may satisfy this requirement, subject to the determination of the Planning Director.

Parking facility interior landscaping. Each unenclosed parking facility of over 5,000 square feet shall provide an interior landscaped area equal to no less than 5% of the total paved area of the parking facility. No more than 200 continuous feet of parking may be provided in a single row without an intervening planting bed or island. Planting beds may also be used to define pedestrian or vehicular traffic flows within the lot. The minimum size of a planting bed or landscaped island shall be 150 square feet. Parking facilities within the LI and GI Districts shall be exempt from any interior landscaping requirement. Licensed automobile dealership display lots are not considered to be unenclosed parking facilities for the purposes of this chapter and therefore do not require interior landscaping as set forth in this section.

Parking lots providing over 400 stalls shall be broken into blocks or units defined by landscaping that include no more than 200 stalls per block.

Landscaping or screening installed in any required landscaped area shall not obstruct the view from the off-street parking facility to any driveway approach, street, alley, or sidewalk. Landscaping shall further not obstruct any views among parking spaces and circulation ways, or visibility between vehicles and pedestrians.

Street landscape border: one deciduous tree and five shrubs; one deciduous tree and one evergreen tree; or 1.5 deciduous trees for each 500 square feet of street landscape border required by § 205-227. A minimum of one tree shall be provided for every 50 linear feet of arterial and collector rights-of-way.

First 100 feet of street yard landscaping: one deciduous tree and five shrubs; one deciduous tree and one evergreen tree; or two deciduous trees for each 1,000 square feet of street yard landscaping. The planting requirement for street yard landscaping shall be calculated by multiplying the area within the first 100 feet of the street yard by the minimum percentage of area of the first 100 feet of street yard to be landscaped established in § 205-227. For example, if the area of the first 100 feet of the street yard of a lot in the CC District is 10,000 square feet, then the calculation is 10,000 square feet divided by 1,000 square feet, which results in a subtotal of 10 planting units. The 10 planting units are then multiplied by 25% for a total planting unit requirement of 2.5 units. The 2.5 units are then rounded to whole number. As such, the lot is required to provide a total of three deciduous trees and five shrubs; three deciduous trees and three evergreen trees; or six deciduous trees.

Buffer yard: one deciduous tree and two evergreen trees for each 1,000 square feet of buffer yard required by § 205-231. Vegetative screens shall be credited toward satisfaction of this requirement.

Parking lot peripheral landscaping: one deciduous tree and five shrubs; one deciduous tree and one evergreen tree; or two deciduous trees for each 500 square feet of landscape area required by § 205-233A.

Parking lot interior landscaping: one deciduous tree for each 20 parking spaces within the parking lot.

Residential development: two deciduous shade or evergreen trees, one in the front yard and one in the rear yard, shall be installed per single-family, townhouse, duplex, attached single-family or two-family dwelling unit. The trees shall be installed prior to occupancy.

Multifamily developments. Multifamily (high-density residential area) developments shall provide one deciduous shade or evergreen tree, or two ornamental trees, and three shrubs for every dwelling unit.

Variety of landscaping. A variety of tree and shrub species shall be utilized to provide visual, four-season interest. Not more than 1/3 of the required number of trees and shrubs may be comprised of any one species and at least 1/3 of the required plants should be a coniferous or evergreen species.

Credit for landscaping.

Obstruction of view. Landscaping or screening installed in any landscaped area shall not obstruct the view from or to any driveway approach, street, alley or sidewalk.

Earth berm locations. All earth berm locations shall be reviewed by the Public Works Director or his/her designee to determine the effect of the berms on drainage and public utilities.

Exceptions. A development may continue to comply with the buffer yard and screening requirements in effect at the time of issuance of its original permit, regardless of whether an adjacent lot or site is subsequently rezoned to a less intensive district that would otherwise require compliance with buffer yard or screening provisions.
