Existing and Proposed Zoning Code Changes
Existing Proposed
R&D Land Use Research and Development —Office.
Facilities that are primarily office uses for
scientific research. This use can include the
design, development, and testing of
biological, chemical, electrical, magnetic,
mechanical, and/or optical components in
advance of product manufacturing. This use
does not involve the fabrication, mass
manufacture, or processing of the products.
Use is permitted by-right in commercial and
industrial zones.
Consolidate definition to from
Research and Development —Office
and Research and Development —
Non-Office into Research and
Development.
Research and Development would
be permitted:
• By-right in non-residential
and mixed-use zones;
• With a Conditional Use
Permit (CUP) in the Public
and Semi-public (PS) Zone.
Research and Development —Non-Office.
A laboratory facility that is primarily used for
non-office scientific research. This use can
include the design, development, and
testing of biological, chemical, electrical,
magnetic, mechanical, and/or optical
components in advance of product
manufacturing. This use does not involve
the fabrication, mass manufacture, or
processing of the products.
Use is permitted by-right in some
commercial and industrial zones and with a
conditional use permit in some commercial
and industrial zones.
CUP
Requirements
The CUP for major construction, specific to
R&D land uses, is only required in certain
zones.
A Minor Conditional Use Permit (MCUP) is
required for any proposed commercial
projects within a ¼ mile radius of a Metro A
Line Station that exceed 15,000 square feet
of gross floor area.
Remove CUP requirement for major
construction over 25,000 square feet
for consistency between zones and
MCUP for projects over 15,000
square feet within a ¼ mile radius of
a Metro A Line
Station.
Parking
Flexibility
Research and Development —Office.
3 spaces per 1,000 square feet Create a parking ratio of 2 per 1,000 square feet. Research and Development —Non-Office.
2 spaces per 1,000 square feet
Building Height Height limit may be exceeded by 10 feet to accommodate additional mechanical
equipment with MCUP
Allow R&D land uses to exceed the
height 12 feet by-right. Any
additional height would require a
MCUP.
Appurtenance
Rooftop
Coverage
The allowable appurtenance roof coverage
for research and development facilities may
exceed the height limit by 15 feet for up to
50 percent of the roof area with MCUP
Allow R&D land uses to exceed the
appurtenance height limit by 18 feet
for up to 75 percent of the roof area.
Any additional coverage would
require a MCUP.
Floor Area
Ratio (FAR)
Requirements
Floor area as permitted by Zoning District. FAR calculations for R&D uses will exclude mechanical spaces.
Open Space Research and Development facilities with
more than 40,000 square feet of non-
residential floor area may reduce the
Common Open Space area requirement by
a maximum of 50 percent, subject to the
review and approval of the Design
Commission.
Research and Development facilities with
more than 80,000 square feet of gross floor
area may reduce the Publicly Accessible
Open Space area requirement by a
maximum of 50 percent, subject to the
review and approval of the Design
Commission.
Projects utilizing an Open Space reduction
shall be restricted to Research and
Development uses for a minimum period of
5 years after Certificate of Occupancy. Any
change of use prior to 5 years shall be
subject to standard Open Space
requirements.
Allow 60% reduction for R&D uses in
all zones where the use is permitted
and to exclude mechanical space
from the floor area calculation in
relation to open space requirements.
Ground Floor
Requirements
Use is not permitted on the ground floor
within 35’ of the sidewalk in certain zones.
Remove ground floor prohibition in
East Colorado and South Fair Oaks
Specific Plans.
Clarify that the use prohibition would
remain in CD-MU-C zone along
Colorado Boulevard and in the CD-
CL zone along the east side of South
Lake Avenue.
