Tempe Zoning + Development Code, Chapter 8 - Lighting
https://library.municode.com/az/tempe/codes/zoning_and_development_code?nodeId=ZONING_DEVELOPMENT_CODE_PT4_DEST_CH8_LI 

• Tempe ZDC requires safe lighting levels throughout all commercial, industrial, institutional, mixed-use, and multi-family parcels citywide
• Exterior lighting used for single-family homes and accessory buildings is exempt from ZDC requirements, provided no measurable light spills over to adjacent properties
• The City of Tempe is an International Dark Sky Community, and recommends all lights be full cut-off and parallel to the ground to prevent light pollution and light trespass
• Code-complaint / safe lighting:
  • Supports way-finding throughout site 
  • Prevents crime
  • Assists people with visual impairments + other accessibility needs
  • Minimizes undesirable light trespass and glare onto adjoining properties
  • Reduces light pollution in the night sky
    
    

Tempe ZDC, Table 4-803 - D. Specific Areas to be Illuminated

* Minimum Illumination Level is measured in foot-candles [FC] at the finished surface. 
This is a requirement throughout each identified area [i.e. parking space]. 
Indicate exact lighting levels on Photometric Plans; do not use averages.

All egress doors have two (2) sets of requirements, each of which are hard-wired for different functions. NOTE: Egress lighting is an adopted building code requirement, whereas, required site and exterior building lighting is adopted ZDC requirement. 

EGRESS LIGHTING [emergency / power failure]			ZDC REQUIRED LIGHTING [exterior building + site]
Required at all egress doors; automatically illuminates in the event of an emergency / power failure.  NOTE: This may not be wired to a photocell or astronomical timer, as it may only be illuminated in the event of an emergency.			Required at all doors / gates. NOTE: All exterior lighting must be full cut-off, dark sky compliant / parallel to ground-plane, and illuminated from dusk-to-dawn by photocell or astronomical time clock. No lighting may contain an adjustable arm; all light types must be fixed-position.

Tempe Zoning + Development Code, Chapter 7 - Landscape and Walls
https://library.municode.com/az/tempe/codes/zoning_and_development_code?nodeId=ZONING_DEVELOPMENT_CODE_PT4_DEST_CH7_LAWA

OVERVIEW + PURPOSE 

To provide minimum commercial standards for the design of landscape treatments and access control landscapes, including plant materials, groundcovers, landscape structures, hardscapes (e.g., plazas, courtyards, walls), screening, and access control devices such as fences and gates. Its purpose is to create functional, safe, accessible and attractive outdoor areas, as well as screen from view any and all uses that may be unattractive to public view.

Landscape design standards are intended to: assist in controlling erosion, reduce dust and glare, provide shade, visually soften building masses, create defensible spaces that support crime prevention, ensure accessibility and aid in screening intense activities. The design standards and referenced guidelines in the Tempe ZDC are intended to be flexible and adaptable to address the context in which they are applied.

STREET TREES
Section 4-703 - Street Frontage Landscape Standards.

https://library.municode.com/az/tempe/codes/zoning_and_development_code?nodeId=ZONING_DEVELOPMENT_CODE_PT4_DEST_CH7_LAWA_S4-703STFRLAST

A.  Street Trees. Trees shall be planted along street frontages, as approved through development plan review. Street frontage landscape shall conform to the following standards:

1.  Street trees are required along all street frontages, public and private; and

2.   A minimum of one (1) tree shall be provided for every thirty (30) feet of lineal street frontage. Tree location and spacing shall be established through development plan review.

PARKING ISLANDS
Section 4-704 - Parking Facility Landscape Standards.

C. Parking Lot Landscape Dimensions. 
All parking areas shall conform to the following standards:

1. What are the requirements for landscape islands in parking areas?

a. Landscape islands shall be provided except when raised curbs are not required where parking areas drain into storm drainage retention features that are integrated into the parking area and landscape design;

b. To ensure adequate soil, water, and area for healthy plant growth, each landscape island shall be a minimum of one hundred twenty (120) square feet in area, a minimum seven (7) feet in width, and a minimum of fifteen (15) feet in length, including curbing. Landscape islands shall extend to the end of the abutting parking space(s);

c. To accommodate pedestrians, landscape islands may be required to include minimum five (5) feet wide raised pathway with wheelchair ramps. For such situations landscape island widths shall be increased to a minimum twelve (12) feet;

d.  Each landscape island shall include, at the time of installation, a minimum of one (1) tree with a minimum caliper of one and one-half (1 ½) inches and five (5) ground covers of one (1) gallon size for each parking space length. All ground covers in parking lot landscape islands shall not exceed two (2) feet in height and be selected from the recommended ground cover and shrub plant list (see Appendix B), and be of a species that will not grow to interfere with natural surveillance of the parking lot. Development plan review modifications to these and other standards shall demonstrate that the alternative provides equal or superior appearance and plant health;

e. Trees with thorns shall NOT be planted in parking islands and near pedestrian walkways or amenity areas.

The planting and replacement of pollen-producing olive trees (olea europaea) or mulberry trees (morus alba), and eucalyptus are prohibited. 

Trees with thorns shall not be planted in parking islands and near pedestrian walkways or amenity areas.

Are there varieties of olive, and mulberry trees which are allowed to be planted?

Olive or mulberry tree varieties or cultivars that are pollenless and fruitless such as "swan hill" olive may be planted or replaced.

What trees are prohibited from being planted in any public right-of-way?

Eucalyptus (except microtheca, papuana, krusena, formanii, erythrocorys, spathulata and torquata), elm (except ulmus parvifolia), willow, cottonwood, or poplar trees.

How close may a tree be planted to a light source?

Tree trunks shall not be placed closer than twenty (20) feet, measured horizontally, from a light source. Trees and lighting shall be located to avoid conflicts with one another and to avoid conflicts with existing and proposed structures. Development plan review modifications to this standard shall demonstrate the alternative does not reduce required lighting levels.

Landscape Irrigation

The valve controller must be in a lockable, vandal-resistant housing and painted a neutral color to match existing surroundings [i.e. beige, desert sand, grass green].

CLEAR VISION REQUIREMENTS

Street Intersections + Driveway Entrances

Except as otherwise approved in writing by the Public Works Director, a wall, building, landscape, or other visual obstruction exceeding two (2) feet in height (measured from street curb, see Appendix B for a list of recommended shrubs) shall not be placed within a "Clear Vision Triangle", including street intersections in single-family zoning districts.

Reference the "Corner Site Distance at Intersections" from the Public Works, Transportation Division. There shall be an exception for a reasonable number of trees pruned high enough to permit unobstructed vision.

Pathways

Groundcovers and shrubs within six (6) feet of pathways shall not exceed two (2) feet in height at maturity. Between six (6) feet and twelve (12) feet of the edge of pathways, groundcovers and shrubs shall not exceed three (3) feet in height at maturity.

See Appendix B and Appendix C for a list of recommended plants. There shall be an exception for a reasonable number of trees pruned high enough to permit unobstructed vision.
