(Ord. 1933 § 1 (Exh. A), 2023)
Certain uses, such as residential developments, can be negatively impacted when located adjacent to incompatible uses, such as industrial sites, due to negative environmental impacts such as noise, glare, and dust. Landscaped buffers and screening can be used to mitigate these impacts, soften the visual transition between developments located in different zoning classifications, and to prevent conflicts between incompatible uses. Landscape screening can also be used to establish visual boundaries or screen certain site improvements such as mechanical equipment, trash enclosures, storage yards, or service areas. The purpose of this section is to identify and prescribe an appropriate range of buffer and screening methods.
A.
The purpose of this section is to accomplish the following:
1.
Establish a buffer between incompatible developments located on adjacent sites with different zoning classifications;
2.
Screen or conceal service areas, trash enclosures, mechanical equipment, storage yards, and other similar site improvements;
3.
Establish a visual transition between streets and adjoining parking areas or drive aisles;
4.
Minimize the environmental impacts associated with freeway and railroad corridors, including light, noise, and air quality impacts;
5.
Prevent conflicts between urban development and rural resource activities such as agricultural uses;
6.
Provide any screening or buffers required as mitigation through a conditional use permit process.
B.
Standard Buffer and Screening Types. This section identifies the standard buffer or screening methods referenced in the Burlington Municipal Code. When a given buffer type or screening method is required by the Burlington Municipal Code it shall be consistent with the specifications identified in this section. These requirements shall be regarded as minimum standards. Additional screening or buffer requirements may apply to specific uses, developments, or site improvements.
1.
Type I – General Screening. General screening is intended to obscure trash enclosures, mechanical equipment, outdoor storage and other similar features.
a.
Minimum Width. The minimum buffer width shall be five feet.
b.
Physical Screening. A solid sight-obscuring fence or wall with a minimum height of six feet shall be provided.
c.
Shrubs. A combination of small and medium shrubs shall be provided. A minimum of one medium shrub and one small shrub shall be provided for every four feet of buffer.
d.
Ground cover shall be provided for all areas not occupied by shrubs.
e.
Exceptions. The landscaped buffer required by this section is not required in areas where a gate, driveway, or path is present.
2.
Type II – Low Wall or Earth Berm. This buffer type is used for screening parking lots, drive-through lanes, drive aisles and other similar features located adjacent to streets. Type II buffers must include both physical screening and landscaping. Physical screening shall be provided using either a low wall, raised planter, or an earth berm as described below.
a.
Minimum Width. The minimum buffer width shall be 10 feet.
b.
Low Wall. If a low wall is used to provide physical screening it shall be constructed of masonry or concrete, and shall have a minimum height of three feet. If the wall is adjacent to a street it shall be set back at least five feet from the right-of-way.
c.
Raised Planter. If a raised planter is used to provide physical screening it shall be constructed of masonry or concrete, shall have a minimum height of three feet, and a minimum width of four feet. If the raised planter is adjacent to a street it shall be set back at least five feet from the right-of-way. The planter shall be completely landscaped.
d.
Earth Berm. Earth berms shall have a minimum height of two feet, a maximum slope of 33 percent (one foot of vertical height for every three feet of horizontal distance). The crest of the berm shall be planted with a row of small shrubs planted at intervals of two feet or less on center to form a dense opaque buffer. The shrubs required by this provision shall be evergreen species and may be used to meet the landscaping requirement in subsection (B)(2)(e) of this section.
e.
Landscaping. Type II buffers shall be planted with a mixture of small and medium sized shrubs at a ratio of one shrub for every four feet of buffer area. Ground cover shall be provided for all areas not occupied by shrubs. At least 75 percent of the required shrubs shall be evergreen varieties.
3.
Type III – Separation Buffer. This buffer type is intended to separate more intensive uses from less intensive uses in situations where the anticipated impacts are largely aesthetic. A type III buffer combines a solid sight-obscuring fence or wall with evergreen trees and shrubs to create a year-round visual screen.
a.
Minimum Width. The minimum buffer width shall be 10 feet.
b.
Physical Screening. A solid sight-obscuring fence or wall at least six feet in height shall be provided.
c.
Landscaping. In addition to any normally required perimeter landscaping evergreen trees shall be provided at intervals of 15 feet or less. The trees required by this provision may be used to meet normally applicable tree planting requirements for perimeter landscaping.
4.
Type IV – High Intensity Buffer. This buffer type is intended to separate high intensity uses with potentially significant light, noise, glare, and dust impacts from less intensive uses. For example, a high intensity buffer would be appropriate for separating an industrial site from a residentially zoned parcel. High intensity buffers must employ a solid site obscuring fence or wall and a dense opaque band of evergreen vegetation. In order to provide adequate acoustic separation, type IV buffers that provide physical screening with a fence, as opposed to a masonry wall, must provide an additional 10 feet of landscaped area.
a.
Minimum Width. If a masonry wall is used the required buffer width shall be 15 feet. If a fence is used the required buffer width shall be 25 feet.
b.
Physical Screening. Type IV buffers must include a solid sight-obscuring fence or wall with a minimum height of six feet.
c.
Landscaping. In addition to any normally required perimeter landscaping triangulated rows of evergreen trees shall be provided at intervals of 15 feet. A minimum of one large shrub for every four feet of buffer area must be provided, 75 percent of which must be evergreen varieties. The trees required by this provision may be used to meet normally applicable tree planting requirements for perimeter landscaping.
C.
Incompatible Uses.

2.
Definition. A significant tree is any tree that is at least six inches in diameter at breast height (DBH). A tree growing with multiple stems shall be considered a significant tree if any one of the stems, when measured at a point six inches from the joint with the main trunk, is at least four inches in diameter. The following species shall not be considered significant trees regardless of size:
3.
Retention. Significant trees shall be incorporated into the project design and site layout whenever possible and may only be removed under the following circumstances:
a.
When absolutely necessary to accommodate a proposed development and where no feasible option exists for incorporating the tree into the overall site layout;
b.
Hazard Trees and Nuisance Trees. Hazard and nuisance trees may be removed with city authorization. In such cases an arborist's report may be required to document the nature and extent of the hazard or nuisance and to demonstrate that no feasible alternative to removal exists.
4.
Significant trees shall be protected during construction or development unless removal is authorized pursuant to this chapter. Temporary construction fencing shall be placed around the tree and no equipment, chemicals, soil deposits or construction materials may be placed within the barrier. When a landscaping plan is required all significant trees shall be identified and a protection plan shall be included. For all projects the department may specify any measures necessary to ensure the protection of significant trees and may require that an arborist prepare the tree protection plan.
5.
Approval Required. Significant trees shall not be removed without prior authorization from the department. An arborist's report, site plan, or other documentation may be required in order to demonstrate compliance with the requirements of this section. In emergency situations where an immediate threat to human life or property exists hazard trees may be removed without city authorization provided the department is notified the next business day. In the event of a natural disaster, such as a flood or windstorm, the department shall be authorized to temporarily suspend all approval and notification requirements.
