IID STANDARDS APPLICABLE TO PROJECT:
• UDC Section 5.12.2. Establishment
• UDC Section 5.12.8 General IID Zoning Option Design Standards
• UDC Section 5.12.6.E Plan Review and Approval Procedures under the IID Zoning Option.
STANDARDS AND REVIEWER COMMENTS:
Apparently, this application is an IID-Application.
It would fall into Stone Sub-Area (STS) of the Stone/Sixth Area (SSA) of the Downtown Links SubDistrict IID (DLS). The following elements would apply:
UDC Section 5.12.8. GENERAL IID ZONING OPTION DESIGN STANDARDS
An IID Plan under the IID zoning option design standards must demonstrate compliance with the
following:
A. Streetscape Design- Streetscape design must comply with the street design standards in the
Technical Manual and the Streetscape Design Policy.
1. Pedestrian-orientation: Projects shall be pedestrian-oriented and comply with all of the following
standards:
a.New construction shall have architectural elements/details at the first two floor levels;
b.Buildings shall provide windows, window displays, or visible activity on the ground floor
for at least 50 percent of frontage;
c.A single plane of façade shall be no longer than fifty feet without architectural detail;
d.Front doors shall be visible or identifiable from the street and visually highlighted by graphics,
lighting, or similar features;
e.Construction and maintenance of sidewalks must be done in compliance with the City's Streetscape
Design Policy. Existing sidewalk widths shall be maintained so as to provide effective, accessible,
connectivity to adjoining properties. Sidewalks may be widened to accommodate a project's design
characteristics. Where no sidewalks exist, sidewalks shall be provided. Outdoor seating and dining
areas and landscaping may be located in the sidewalk area where safe and effective sidewalk width
around the design feature can be provided;
f. To the extent practicable, bus pull-outs shall be provided where bus stops are currently located;
g. If drive-through service is proposed, it shall not interfere with pedestrian access to the site from
the right-of-way.
2. Shade
a.Except as provided below, shade shall be provided for at least 50% of all sidewalks and pedestrian
access paths as measured at 2:00 p.m. on June 21 when the sun is 82 degrees above the horizon.
Shade may be provided by trees, arcades, canopies, or shade structures provided their location and
design characteristics are compatible with the historic and design context of the street and the
architectural integrity of the building. The use of plantings and shade structures in the City right-ofway is permitted to meet this standard with the approval of the Transportation Department. The
shade provided by a building may serve to meet this standard.
b.Exception- The PDSD Director may approve an IID Plan providing less than 50% shade where
compliance is not feasible due to a project site's location and/or building orientation and the
applicant has made a reasonable attempt to comply with this standard.
B. Development Transition Standards
The purpose of the Development Transition Standards is to mitigate excessive visual, noise, odor,
vibration intrusion, and other similar public health and safety concerns that may be created by the
proposed project.
1.Applicability - Developing sites that abut an affected single family or duplex dwelling shall comply
with this section. For purposes of the IID, the following terms and examples describe elements of
applicable transitional areas:
a."Affected residential property" refers to an existing detached single-family or duplex dwelling that
is adjacent to a developing site;
b."High density residential" refers to residential development that is neither existing single-family
detached nor attached dwellings;
c. Examples of applicable transitional areas include a nonresidential developing site adjacent to
existing single-family detached or attached dwellings within a subdivision, or a developing highdensity residential site adjacent to existing single-family detached or attached dwellings within a
subdivision; and,
d.For projects within the DCS, the Development Transition Standards apply only to those projects
adjacent to affected residential properties outside the DCS boundaries.
Not applicable.
2.Mitigation of Taller Structures: Compliance with the following standards is required where the
developing site has taller buildings than adjacent affected residential properties:
a.Within the GIIS and DCS, the maximum building height is 25 feet within 30 feet of the property line
adjacent to an affected residential property. Proposed buildings may be developed to the maximum
height permitted by the underlying zone or as permitted by the IID Subdistrict, whichever is
applicable, when the building is 30 feet or more from the property line adjacent to an affected
residential property;
b.Building Bulk Reduction
c. If a building façade faces a property line adjacent to a single-family detached or duplex residential
property, the PDSD Director may require bulk reduction. The Design Professional shall make a finding
and recommendation, after consulting with the DRC and/or Historic Commission if applicable, that
the proposed design provides an effective way of breaking up the mass, so the building mass of the
façade is less imposing.
d.Balconies shall be oriented away from affected residential property or use a screening device to
reduce views into the rear or side yards of the affected residential property.
e.The developing site's buildings shall be oriented so as to reduce views onto an affected residential
property; and
f. Buffers and/or screening consistent with the purpose of this section shall be provided between a
developing site and affected residential properties and shall include features such as, but not limited
to, landscaping, walls, and architecturally decorative features.
3.Mitigation of Service Areas- Potential nuisance or noisy areas shall be oriented away from affected
residential property, such as by placing service areas for loading and garbage disposal between the
developing site's buildings, behind opaque barriers, or by using architectural or landscaping
treatments that effectively reduce nuisance impacts from service areas. The service area shall be
mitigated to reduce the noise and view of the service features, reduce the emission of offensive
odors to owners or occupants of adjacent properties or create a nuisance or hazard beyond the
property lines of the project site, and prevent vibrations that are discernible beyond the property
lines of the project site.
4.Mitigation of Parking Facilities and Other Areas- Where the site has parking areas or an area with
noise and outdoor lighting features, the areas shall be screened from affected residential property by
a combination of a wall or opaque non-chain link fence with a vegetative hedge or a row of trees that
shall be dense enough to screen views onto the development site. An alternative treatment may be
used, such as using architectural or landscaping treatments that effectively reduce nuisance impacts
from parking facilities and other areas. Where there is a finding that the vegetative screen will be
opaque, the requirement of a masonry wall may be waived by the PDSD Director.
C. Alternative Compliance
1.The PDSD Director may approve an urban design best practice option for compliance with Section
5.12.8.A, Streetscape Design, and Section 5.12.8.B, Development Transition Standards.
2.For purposes of this section, urban design best practices may include urban design studies
approved for the City of Tucson, adopted urban design standards for a downtown area in an Arizona
city of comparable size or a city in the Southwest of comparable size, books written by urban design
experts or endorsed by a professional organization, such as the American Institute of Architects,
addressing downtown development , or any comparable report, study, or standards recommended
by the City's Design Professional and approved by the PDSD Director.
D. Utilities- Plans shall include information on the layout and demonstrate availability of utilities
such as water, wastewater, natural gas, electric, and telecommunication utilities.
E. Parking
1.Parking spaces may be located as follows:
a.On site; or
b.Off-site within ¼ of a mile of the project site under a shared parking agreement that is approved by
the City.
2.Required vehicle and bicycle parking may be reduced pursuant to an IID Parking Plan in accordance
with Section 7.4.5.A, except as modified as follows:
a.Section 7.4.5.A.3 in Permitted Uses and Types of Development does not apply. An IID Parking Plan
may be used to reduce required residential parking.
b.Bike parking shall be provided when motor vehicle parking is provided. The PDSD Director may
reduce the required number of bike parking spaces depending on the use, setting, and intensity of
the proposal.
c. The neighborhood meeting that is required for under Section 7.4.5.A.6.a may be held concurrently
with the neighborhood meeting required by Section 5.12.6.B.
d.Section 7.4.5.B, Downtown Parking District, does not apply.
3.Where Parking is provided, the parking area must comply with the standards of Section 7.4.6.C and
D.
4.Parking must be in a parking structure with the ground floor of the parking structure screened from
view.
a.Exception
b.Parking may be located on a surface parking lot if it is determined by the PDSD Director to be
impracticable to be located elsewhere and other options are not available.
c. Parking may be located on a surface parking lot if it is determined by the PDSD Director to be
impracticable to be located elsewhere and other options are not available. If located onsite, parking
areas must be located at the rear or side of the building.
d.Changes of use and expansion of existing structures may use the site's current parking
configuration.
e.Parking structures shall be designed so that parked vehicles are screened from view at street level
through incorporation of design elements including, but not limited to, landscaping, pedestrian
arcades, occupied space, or display space.
5.Special IID Parking Agreement- Where a developer can demonstrate to the satisfaction of the PDSD
that the parking options provided for in this Section are not feasible, and the City makes a specific
finding that the project will have significant economic development value for the IID Sub-District in
which it will be located, the following parking options are allowed as follows:
a.A percentage of long-term residential parking may be located in a City public parking garage by an
agreement with Park Tucson if the project is of significant economic benefit to the City to allow this
option.
b.The agreement must be reviewed by PDSD, the Design Professional, Park Tucson and approved by
the City Manager.
F. Multi-zone Parcels- Where a development parcel contains more than one zoning district, uses and
building massing may be distributed across the zoning districts on the parcel , provided that the
development complies with the design standards in Section 5.12.8.B to mitigate the impact of the
new development on existing, less intensely developed adjacent parcels.
Section 5.12.6.E – IID Historic Preservation Review
2. Projects not in an HPZ
a. The Tucson-Pima County Historical Commission (TPCHC) Plans Review Subcommittee reviews all
projects listed below:
(2) Projects proposing new development using IID zoning option that are either adjacent to the
boundaries of an HPZ or adjacent to a structure meeting any one or more of the following
characteristics:
(a) Listed or eligible to be listed in the National or Arizona Register of Historic Places, individually or as
a contributing property.
d. The TPCHC Plans Review Subcommittee reviews for compliance with the design requirements of
the applicable sub-district and for design compatibility of a proposed development project.
(1) New development must be designed to complement and be compatible with the architecture of
adjacent historic structures.
(2) Compatibility with adjacent historic structures is to be achieved through architectural elements
such as building setbacks, building step-backs, textures, materials, forms, and landscaping.
In addition, the regulations of IID-DLS-SSA-STS, pages 83 – 88 apply.
It should be noted that the situation of this project on this lot is not well defined by the diagrams in
the IID-DLS-SSA-STS. A careful application of those principles will have to be presented and discussed
by the applicant in their eventual submittal.
It should also be noted that the application has the HPZ box checked, when in fact this site is not in an
HPZ. Crosshatch is West University HPZ. Light Blue is both National Register Districts John Spring
Neighborhood and Miracle Mile District. “C” is contributing structures. “N” is Non=Contributing
structures. Red Star is this site.
Issues of concern by this Design Professional Review (to be discussed in final submittal):
• Compliance with diagrams in IID-DLS-SSA-STS.
• Height and impact on adjacent structures.
• Constructability
• Elevation compatibility with adjacent Contributing Structures
• Development Transition Standards
Would this have a better chance of compliance using underlying zoning?

There is an existing 4-inch PVC water main on the west side of the property, and an existing 12-inch PVC water main on the east side of the property in Stone Avenue. The closest fire hydrant is on the southwest corner of the Stone Avenue and 1st Street intersection.
The static water pressure in this area is in the 48-55 psi range. A private on-site booster station may be necessary to provide adequate water pressure to the upper floors of this proposed multi-story development.
After a water fixture unit count has been conducted for the project using the 2018 International Plumbing Code, and the fire flow requirements for this project have been established by the local fire authority, please contact Ray Munoz at 837-2207 in the Tucson Water New Services Section to discuss:
Potential points of connection to Tucson Water’s existing water distribution system. Please note that hydraulic modeling may need to be performed to verify which potential points of connection have the capacity necessary to serve the potable water and fire flow demands of the proposed development.
The number of water service lines, water meters, and meter sizes, necessary to serve this development.
The advantages and disadvantages of installing the necessary water meters via Tucson Water’s Job Order Contract (JOC) process.
