Street Yard

The area behind the street right-of-way, and, in front of any building on private property is known as the street yard. Street yard design standards prevent property owners from paving right up to the front property line. The purpose of a street yard or street yard buffer is to improve the view from the public roadway, to promote ingress and egress safety and to partially screen visually complex urban development such as parking lots, storage facilities, vehicular use areas and unattractive buildings.

Street yard buffer planting requirements often require a minimum number of shade trees shrubs and ground covers other than turf grass spaced within a strip of land attached to the front property line. The panting strip is calculated by square footage or is based upon depth. A common street yard depth is ten (10) to fifteen (15) feet with some communities increasing this to as much as thirty feet. Some codes require this planting place to include all of the land in front of buildings to prevent the construction of parking lots along roadway edges. Other communities base the depth of this planting strip on the depth of the perpendicular property line. Ten percent of the length of the site is not uncommon. 

Exceptions are often granted to businesses that want to use their street yards as a sales display areas. But, they may need to apply for and receive a zoning variance. Used car lots, open air markets and retail plant nurseries are always a problem in community landscape codes in regard to this exception.

Much of this open space of the street yard, is the open space between the front property line and the building wall. The street yard may be a free floating amount of area between the front property line and the building or it may be attached directly to the front property line.  An alternative of the street yard is the “street buffer strip.” This is a certain sized strip of land attached to the front property line in which all existing trees must be preserved.

 

Calculations

Planting Area

Street Length= Property Line (facing street) = Property Line (facing street)

 

Street Yard Area= Street Length X Ten (10) Feet (or One Tenth (1/10) of Lot Depth

 

Shrubs and Ground Cover Planting Area= Street Yard Area X Coverage Percentage

 

No more than fifty (50) percent of a street yard buffer may be devoted to storm water management. Swales should be designed as curvilinear features that maximize length, vary in width, and not exceed twelve (12) inches in depth.

 

Street yard buffers contain a minimum number of Class A or Class B trees for every six hundred (600) square feet of street frontage or fraction thereof, measured at the property line. The street yard planting area shall contain shrubs and ground cover a designed percentage of the planting are. The trees, shrubs and ground covers can be arranged in any manner within the ten (10) foot depth or a minimum of one tenth (1/10) of the lot depth.

 

 

General Design Standards for Street Yard Planting Area

Planting requirements for street yards are generally based upon some combination of linear foot measure, square foot measure, plant material density, plant material spacing standards, a ratio of species types and design considerations, such as size, form, color, or seasonal interest of certain plant materials. Trees for interest may be planted bases upon spacing. Forty (40) to sixty (60) feet on center is common for Class A trees and twenty (20) to twenty-five (25) feet for medium sized Class B trees. Shrubs and ground covers plantings are often based up a percentage of coverage of the planting area or perhaps opacity. The ability of trees and shrubs to block views is an important design feature of the landscape architect stock and trade.  Plantings need not be linear and formal but may be informal and clustered. Designers are often encouraged to use innovative and creative ways to arrange the required plant materials within the required planting area.
