|
15 ft. average with min. 10 ft. (max. 40% of an elevation can

|
|
Interior property line (abutting res. zone) (7)
|
• Abutting R1/GH zone, one of following options: (1) 30
ft. with a min. step-back of 20 ft. above the height of 35ft.; OR
(2) 100 ft. setback with no step-back; OR (3) 30 ft. with height averaging
as noted below in the height section.
• Abutting R2, R3, and R4 zone, one of the following options:
(1) 10 ft. setback with an average step-back of 10 ft. above the height
of 45ft.; OR (2) 20 ft. setback with no stepback; OR (3) 10 ft. with
height averaging as noted below in the height section.
• Interior setback areas may be counted toward private
open space (not public open space requirement) when landscaped and
designed for functional use by the residents.
|
|
Upper Level Step-Back (7) (10) (11)
|
• MU-1 Zone: an upper level step-back of 15 ft. average
of all street-facing upper floors above 35ft.
• MU-2 Zone: an upper level step-back of 15 ft. average
of all street-facing upper floors above 45ft.
Exception: Average step-backs do not apply along interior property
lines abutting R1/GH zones (See setbacks from interior property lines
abutting residential zones).
|
|
Height (1) (3)
|
A baseline height is provided for the MU-1 and MU-2 zones and
adjustments above the baseline are permitted as provided below:
|
|
Baseline Height
|
6 stories & 65ft. (see height modulation)
|
5 stories & 55ft. (see height modulation)
|
|
Height Modulation (9)(12)
|
A square box is not an acceptable design and the modulation
of the heights is required to provide visual interest and reduce the
scale of building mass. Accordingly, a proposal shall include a building
step-back on the street frontage and at least two of the following
elements:
|
|
• Height variation: a change in roof heights of at least
10 ft. every 150 linear ft.
|
|
• Height averaging: Height averaging where a portion of
the building may exceed the baseline height provided that the height
of the entire project is equal to or does not exceed the baseline
height. Except that within 100 ft. of a R1 & GH Zone, the height
of the building shall not exceed 45ft. and within 50 ft. of a R2,
R3, & R4 Zone, the height of the building shall not exceed the
baseline height (above). (12)
|
|
• Corner: A ground level plaza or a prominent corner feature
that is differentiated by height and design features from the primary
massing of the building by a minimum of 10 ft. To qualify, corner
feature shall have a measurement of at least 25 linear ft. in each
direction.
|
|
Open Space (10)
|
Projects shall provide open space that is both accessible to
the public and open space that is for the exclusive use of on-site
residents based on the following formula:
• 10% of gross site area (<2 acre site), OR 15% of gross
site area (>2 acre site); PLUS
• 100 square feet per residential unit (includes live-work
units)
The total open space requirement resulting from the above calculation
shall be distributed between publicly accessible open space and private
open space as noted below:
|
|
Publicly accessible open space
|
• A minimum of 50% of the required open space must be publicly
accessible and located along the street frontage or directly accessed
from a public sidewalk.
|
|
Private open space
|
• Private open space may be provided in any combination
of the following three ways:
Additional publicly accessible open space above
the minimum requirement.
Common open space for residents only (interior courtyards
and decks).
Private balconies and patios (min. dimension of
4 ft.)
• A min. of 20% of the total required common open space
for residents must be landscaped with live plant material.
|
|
Façade and Massing Variation
|
Blank expanses of walls and lack of variation in the façade
is not an acceptable design. Recesses and projections of the façade
in combination with changes in colors, materials, and articulation
create the desired quality and visual interest. In every building
frontage, at least one of the following elements shall be incorporated:
|
|
Modulation
|
Major recess/projection of at least 2 ft. depth and 4 ft. in
width every 150 linear ft. plus a minor recess/projection of at least
1 ft. depth and 2 ft. in width every 50 linear ft.
|
|
Delineated base, middle, top
|
• Change in materials (acceptable street level materials
include a preponderance of brick, wood, stone, or similar detailed
materials. Above the first floor, no more than 80% of an elevation
may be clad in EIFS or stucco); or
• Design that creates distinct vertical and horizontal
visual separation through color, material, cornice trim, and/or awnings;
or
• Upper level step-backs.
|
|
Building Separations (10)
|
A building separation shall be provided on each street facing
building elevation of 250 linear feet or more through at least one
of the following means:
• A building separation of an average width of 40 ft. and
an average depth of 25 ft. with a minimum 1,200 sf of area that extends
to the street level and is open to the sky; OR
• A building separation that begins at the second floor
of an average width of 40 ft. and an average depth of 20 ft. that
is open to the sky. The ground level floor within the separation area
must be set back an average of 5 ft. from the main building façade.
|
|
Between separate structures
|
10 ft. min. with an average of 20 ft. except 15 ft. average between sidewalls and front or rear of other buildings. No setbacks are required between buildings with no openings on adjoining walls. See Section 21.08.050(b) for accessory structures.
|
|
Minimum residential floor area (8)
|
Minimum floor area requirements for residential units. Per Section 21.08.040, Residential zoning district general development standards, Table 2-4.
|
|
Minimum residential storage areas
|
Each dwelling unit shall have a minimum of 200 cubic feet of
individually enclosed, weatherproofed and lockable storage space.
Such space shall be for the sole use of the occupant of the dwelling
unit and may be provided within individual storage lockers, cabinets
or closets within the garage area if neither the space nor the doors
leading thereto overhang a parking space assigned to another unit.
Storage areas inside units must be separate from typical forms of
interior storage including closets, pantries, linen closets, and kitchen/bathroom
closets.
