The purpose of the tower mass reduction in the DT districts is to provide interesting buildings that create a positive interaction with the street to reflect northern climate aspects in the visible and built form. Tower mass reductions provide the opportunity to reduce the adverse environmental impacts of tall buildings on the downtown streetscape. These standards were determined based on input from architects, landscape architects, and engineers weighing flexibility for development with design best practices.

Minimum tower mass reduction requirements:

For all floors above the tower mass reduction height noted in section 21.11.070C.2a, the Gross Floor Area (GFA) of each floor shall be smaller than the floor with the largest GFA below that height.

The tower mass reduction shall occur on all building frontages on a street or exterior public space, and the size of the reduction shall be governed as noted in Table 21.11-6.

The GFA reduction may be applied to all floors above the tower mass reduction height independently.

After the reduction has been applied, only a maximum of 20 feet or ten percent of the frontage (whichever is greater) may be aligned with the facade of the floor governing the reduction.

The tower mass reductions shall be cumulative for buildings with frontages on multiple streets or public spaces. For example, a building on a corner lot adjacent to a street 70 feet or greater and a street with a width smaller than 70 feet shall reduce all floors above the tower mass reduction height by 12 percent.

Minimum sidewalk widths in the DT zoning districts shall be as follows:

Sidewalks shall be located abutting the street curb or in an enclosed mall or arcade connected to adjacent pedestrian circulation facilities.

Visual access windows. Exterior walls located 20 feet or closer to a street ROW shall meet the window standards in Table 21.11-7.

Ground-floor street-facing exterior walls located 20 feet or closer to a street ROW or a public space shall include a minimum of one building entry within 70 feet of the building corner. A building entry at a building corner may be counted as an entry for both corner walls. The maximum distance between entries on a single frontage shall be 70 feet.

Building entries must open into a circulation space or an occupiable space and must be intended for regular use by building users. Exit-only doors are exempt from this requirement. If building entries are recessed, they shall meet the building recess visual access requirements of section 21.11.070D.2.b.i and Figure 21.11-1.

Textured siding. Siding material that adds visual interest with a highly textured surface, applied up to a minimum height of 48 feet, may be used to meet this standard. Textured siding modulations deeper than twenty-four inches shall meet the building recess and modulation visual access requirements of section 21.11.070D.2.b.

Building articulation. To meet this standard, the building wall and foundation line shall be offset at intervals so that there is at least one offset every 20 feet of wall length that varies the depth of the building wall by a minimum of 24 inches. Offsets shall comprise at least 60 percent of the length of the elevation receiving the treatment and be applied up to a minimum height of ten feet.

Public art. The art shall be constructed with weatherproof, durable, and permanent materials or paints. If the art takes up less than 60% of the height of the building frontage where it is applied, up to 48 feet in height, it must be combined with another building frontage design treatment from Table 21.11-8.

Landscaping.

Decorative street lighting. Intent Decorative illumination fixtures are intended to promote an increased sense of vitality and cohesion in downtown street corridors and provide additional levels of illumination for increased pedestrian safety and comfort.

Canopies. For the purposes of this section 21.11.070D.2.f, the following provisions replace the pedestrian shelter including canopy design standards of section 21.07.060F.9. The pedestrian shelter definition at the beginning of section 21.07.060F.9 applies.

Sidewalk canopies are intended to improve downtown pedestrian comfort and safety, especially during winter months and inclement weather. Canopies may also provide increased street and building design continuity and support a wider range of pedestrian corridor activities.

Plazas. For the purposes of this section 21.11.070D.2, the following provisions replace the design standards of section 21.07.060F.6.

Institutional, commercial or industrial uses adjoining a residential district: Visual enhancement landscaping and a screening fence.

Residential uses adjoining a residential district: Visual enhancement landscaping, or a screening fence and an area landscaped with parking lot interior landscaping equal to five percent of the paved surface of the parking area including parking circulation aisles and appurtenant driveways.

A parking area serving only a single-family, two-family, or three-family dwelling is exempt.

Visual enhancement landscaping shall be planted on the perimeter of the parking area abutting a lot line, or a screening fence shall be placed on the perimeter of the parking area abutting a lot line and an area equal to at least five percent of the paved surface of the parking area, including parking circulation aisles and appurtenant driveways, shall be devoted to parking lot interior landscaping. Exceptions are:

A foundation planting bed or walkway, or both, at least four feet wide shall separate the parking area, including circulation aisles and appurtenant driveways, from any building on the same lot.

In addition to the landscaping required under subsections E.2.a.i and E.2.a.ii of this section, parking lot interior landscaping shall be planted within the interior of a parking lot containing more than 60 spaces. The area devoted to parking lot interior landscaping shall equal at least five percent of the paved surface of the parking area including parking circulation aisles and appurtenant driveways.

The vehicle overhang allowance area of parking spaces may extend into required landscaping areas by up to two feet, provided the planting bed beyond the overhang is at least six feet wide.

Trees shall be set back a minimum of 3.5 feet from the back of curb to reduce the possibility of damage from car doors and splash from cars. Tree guards may be considered for protection of trees where large numbers of people may gather.

A sloping six-inch minimum (12-inch preferred) wide apron (1V:12H) around tree grates may be considered for pedestrian circulation while protecting the growing medium from sidewalk runoff with high concentrations of melting agents. Tree grates must be designed to recognize the need for accessibility for all.

Trees specified for the downtown districts shall be species that branch (or can be successfully trimmed at maturity) at eight feet.

Landscape beds, planters, and tree grates shall remain a minimum of 30 inches clear of the back of curb.

Sidewalk width between the edge of the planting bed, raised planter, or tree grate and the building shall be minimum six feet clear.

Planters shall be designed and plant species shall be selected and placed so that when the plants reach mature height visual access is maintained through the entirety of the planting bed from 30 inches to 72 inches in height as measured from the closest paved pedestrian surface. Planter height shall be no more than 24 inches from the sidewalk.

Minimum size of shrubs may be reduced from 18 inches in height to 6 inches in height when planted in a raised planter that raises the surface of the planting bed a minimum of 18 inches.
