   4. Professional/office buildings shall require at least 15 percent of the total lot be landscaped.
      1. A ten-foot-wide minimum landscaped area shall be provided around the entire building, with the exception of where loading docks, ramps, etc., are located. Up to five feet of said ten-foot minimum may be sidewalk. The administrative land use authority may provide for an exception to this requirement if soil types make it inadvisable to have irrigation near the building. In such case, the required amount of landscaping shall be provided elsewhere on the property.
   5. Industrial/warehouse buildings shall require at least ten percent of the total lot be landscaped.
      1. A ten-foot-wide minimum landscaped area shall be provided around the entire building, with the exception of where loading docks, ramps, etc., are located. Up to five feet of said ten-foot minimum may be sidewalk. The administrative land use authority may provide for an exception to this requirement if soil types make it inadvisable to have irrigation near the building. In such case, the required amount of landscaping shall be provided elsewhere on the property.
   6. Parking areas. Landscaping in parking area shall be designed to provide the following:
      1. Incorporate appropriate plantings that are in scale with their surroundings.
      2. Separate roadways, travel paths, pedestrian paths etc., using landscaped islands and/or planter strips.
         1. Define area where pedestrians are safely separated from the travel path/roads.
         2. Reinforce way-finding by emphasizing entrances and circulations patterns.
      3. Add aesthetic value, provide canopy shade, reduce radiant hear from the surface, reduce headlight glare, and add seasonal interest.
      4. When possible, preserve mature trees and other significant landscape features which help define the character of the city.
      5. When planted parking medians are used, they shall be a minimum of ten feet, six inches wide.
      6. Planted islands shall be a minimum of 25 square feet.
   7. Xeriscape. Xeriscape is landscaping that reduces or eliminates the need for supplemental water from irrigation. It is different from natural landscaping, because the emphasis is on selection of plants for water conservation, not necessarily selecting native plants. Xeriscape landscaping can work well in the state's desert climate. Xeriscape landscape is not zero-scape; it is an area filled with color, scent and variety. Trees can be used effectively in xeriscape and with property planning, planting, and care, they will thrive in low-water landscape.
   8. Low impact development (LID). LID is a stormwater management approach with a basic principle that is modeled after nature: manage rainfall at the source using uniformly distributed decentralized micro-scale controls. LID's goal is to mimic a sites predevelopment hydrology by using design techniques that infiltrate, filter, store, evaporate, and detain runoff close to its source. Developments are encouraged to implement LIDs.
   9. Trees. One tree (minimum two-inch caliper, minimum ten feet in height) shall be planted and maintained for each 1,000 square feet of landscaped area. Trees in portable planters shall not qualify to meet the tree requirements.
      1. Trees within overhead utility easements shall be of a type that customarily grows to a height not exceeding 15 feet.
   10. Plants. The selection of plant materials should consider public health and safety. Plants to be avoided include those with poisonous fruits, large thorns, or invasive growth patterns. The ultimate form and height of plantings as they mature should be considered so they will not create unsafe conditions or block sight lines for pedestrians, bicyclists, or motorists.
       1. Planting beds may be mulched with bark chips, decorative stone, or similar materials. Mulch shall not be used as a substitute for plants.
   11. Landscaped buffer. The term "landscaped buffer" means a landscaped area whereby trees and other plan materials are used to create a wide, landscaped park- or garden-like area around the perimeter, or in the side and/or rear yard, of a property in order to physically and visually separate and mitigate undesirable environmental impacts (such as noise, dust, stormwater, etc.) between commercial zones and residential zones. Generally accepted scale for landscape buffers. The following minimum and maximum width of transitional yards and screening should be used between commercial and residential uses:
       
       1. Minimum width: Ten feet.
       2. Maximum width: 50 feet.
       3. Where commercial buildings are less than 5,000 square feet in area, a minimum ten feet buffer is substantial. Otherwise, if the building area is greater than 5,000 square feet in area, a landscape buffer should be a minimum 25 feet.
   12. Planting materials in the landscape buffer.
       1. Choose plants that will naturally grow to the desired form or height to reduce maintenance. No limbing up (this will lessen the life and strength of the tree).
       2. Tree canopies should have a natural growth height of at least eight feet from the ground when located around areas in the clear-view area (see PCC chapter 10-9). Tree canopies should have a natural growth height of at least four feet from the ground when located around parking areas, walkways, etc.
       3. New trees and shrubs should be evenly spaced at planting, with trees having an eight-foot minimum installed height, and shrubs having a 36-inch minimum installed height.
       4. Landscaping in the landscape buffer should consist of a minimum of six large maturing trees (minimum 50 percent evergreen) and 40 medium shrubs (minimum 75 percent evergreen) for each 100 linear feet, to provide continuous coverage. For dimensions of less than 100 feet, plantings and spacing will be in proportion to the basic ratio.
   13. Snow storage. Landscape materials surrounding parking lots and in islands and medians should be able to tolerate large quantities of snow stored during winter months. Delicate plant material should not be used in area where they are likely to be damaged by snow.
   14. Lighting. The intent of lighting is to provide the necessary lighting to ensure pedestrian safety, night vision for pedestrians and automobiles, add aesthetic value to the city appearance, and not create or cause excessive glare onto adjacent properties.
       1. Lighting height and location shall be designed to illuminate the site only. Light cutoffs are required to prevent spillover of direct light.
       2. Pedestrian street lights or lamp posts located within the public right-of-way are required in all commercial zones.
       3. Pedestrian street lights or lamp posts located within the public right-of-way shall be mounted between eight feet to 16 feet above grade to provide illumination of street sidewalks.
       4. Pedestrian street lights or lamp posts shall reflect the architectural design characteristic of the surrounding area.
       5. Up-lighting is not permitted, except as approved through the site plan review for highlighting signature landscape features or building elements.
       6. HID or fluorescent tube lights (except compact fluorescent bulbs) are not permitted as exterior building lights.
       7. Floodlights or directional lights permitted for the lighting of alleys, parking garages and outdoor working areas must be shielded or directed to prevent the source of light (bulb or lamp) from being seen from adjacent properties or public rights-of-way.
   15. All landscape plans submitted for approval shall contain the following information unless specifically waived by the city. At the discretion of the city a final landscaped plan may require a stamp from a state licensed landscape architect.
       1. The location and dimensions of all existing and proposed structures, property lines easements, parking lots and drives, roadways and rights-of-way, sidewalks, bicycle paths, ground signs, bicycle parking areas, fences, freestanding electrical equipment, tot lots, and other recreation facilities.
       2. The location, quantity, size and name, both botanical and common names, of all proposed plants.
       3. The location, size and common names, of all existing plants including trees and other plants in the parkway and indicating plants to be retained and removed.
       4. The locations of existing buildings and structures on adjacent property within 20 feet of the site.
       5. Location and heights of fences and retaining walls proposed on the site.
       6. At the discretion of the city a final irrigation plan may require a stamp from a state licensed landscape architect.
   16. Completion; performance security. No requests for any building, structure or other improvements shall be approved until site and landscape plans have been approved by the administrative land use authority; and a preconstruction meeting held.
       1. Preconstruction meeting. A pre-construction meeting will be held with the developer, general contractor for the development, and city staff prior to beginning any construction in the development, including grading and trenching.
          1. It is the developer's responsibility to notify the general contractor and all appropriate subcontractors for the development of their required attendance at the preconstruction meeting and that no construction can commence until after that meeting.
          2. The stormwater notice of intent (NOI) and stormwater pollution prevention plan (SWPPP) must be in place prior to the preconstruction meeting.
       2. Landscaping and site developments in accordance with the approved plans shall be installed within 30 days following occupancy of the building.
       3. If said completion date is impossible due to adverse weather conditions, a mutually agreed-upon completion date shall be determined by the city and the applicant, but in no case shall the completion date be more than 150 days from the date of occupancy. The developer (or owner) shall hereby deposit a security of performance as specified in PCC 11-5-7B through C as security to ensure compliance with all landscaping and site requirements. If the developer or an agent of the developer fails to comply with the above installation and time requirements, the security of performance may be foreclosed upon by the city to cover costs of installing, repairing or replacing said landscaping and site developments.
4. Undeveloped area. All areas of the parcel on which development is taking place shall be regulated by this chapter. Land which is not covered by the building, parking lots, roads, landscaping or otherwise improved shall, as a minimum, be restored with natural vegetation and maintained so as not to create a weed nuisance (see PCC chapter 2-4), or the area may be maintained in agricultural production.

The narrative should also describe the proposed timeline for completion of the entire project and any proposals to bond for required unbuilt or yet-to-be constructed improvements.
       6. Choosing to phase a development does not relieve the developer of the requirement to present the entire development in its phases for preliminary approval by the planning commission. Nor does it relieve the developer of the requirements to extend all public infrastructure to the boundary lines of the development.
5. Project approval process.
   1. Procedure. In addition to the actions and considerations listed in this section, developers shall be required to follow the approval procedures outlined in this Code.
