This division contains the performance standards and regulations pertaining to the landscape elements of residential, commercial, and industrial properties; requirements for the provision of trees along public rights-of-way; maintenance requirements for trees and other landscape components adjacent to public rights-of-way; and administration and enforcement of these regulations.
[Ord. No. 3375, § 1, 9-12-1995]
(a) 
The purpose of this division is to establish minimum standards for the provision, installation, maintenance, and removal of landscape plantings in order to achieve a healthy, visually pleasing, and safe community by the following means:
(1) 
Preservation of vegetation. Preserve existing natural vegetation and the incorporation of native plants, plant communities, and ecosystems into landscape design, where possible.
(2) 
Aesthetics. Improve the appearance of all areas through the incorporation of open space into development in ways that harmonize and enhance the natural and built environment.
(3) 
Land values. Maintain and increase the value of land by requiring landscape improvements to be incorporated into development, thus becoming by itself a valuable capital asset.
(4) 
Human values. Provide direct and important physical and psychological benefits to human beings through the use of landscape materials to reduce noise and glare, to provide visual diversity and seasonal interest, and visually soften the harsher aspects of urban development.
(5) 
Improved design. Promote innovative and cost-conscious approaches to the design, installation, and maintenance of landscaping, encouraging water and energy conservation.

(a) 
The following standards shall be considered the minimum requirements for the installation of all plant materials on lots or within public rights-of-way in all zoning districts:
(1) 
Size; digging.
a. 
Size specifications. Unless otherwise stated in this division, all size specifications for plant materials shall be based upon the time of planting. When minimum caliper is specified for tree plantings, the caliper of the tree trunk shall be taken at six inches above the ground level, up to and including four-inch caliper size, and 12 inches above ground for larger sizes.
b. 
Digging in street rights-of-way or easements. It shall be the responsibility of the person planning to install plant materials, within a street right-of-way or a utility easement, to notify any utility company or public agency having any underground utilities within such right-of-way or easement. This notification shall take place prior to any digging and all work shall be in accordance with any rules and regulations as provided for by local or state law or by regulations of the utility companies or public agency.
(2) 
Minimum tree and shrub planting or preservation requirements.
a. 
Interference. Trees shall not be placed where they interfere with site drainage or where they shall require frequent pruning in order to avoid interference with overhead utility lines.
b. 
Acceptable tree species, cultivars, or varieties. Trees planted on existing developed sites, in conjunction with new developments and within public rights-of-way within all zoning districts, shall be of the species, cultivars, or varieties listed in tables 1 through 4, on file with the City, except as otherwise provided herein. The species, cultivar, and/or variety which are listed in table 4 are not acceptable for planting within the public rights-of-way due to susceptibility to salt damage, potential for impeding sight-distance visibility, susceptibility to disease, potential for growth into street pavement areas, and other potentially undesirable effects of such plantings. The Director of Public Works shall have the right, from time to time, to modify, delete or add to the species, cultivars or varieties listed in such tables.
c. 
Undesirable tree species, cultivars, or varieties. In order to protect the City's existing trees from disease, to ensure that the species and varieties of trees which are planted will grow and be healthy, will be resistant to storms, and do not present other undesirable effects, the trees listed on file with the City, shall not be planted on existing development sites, in conjunction with new developments or within public rights-of-way in any zoning district, except upon the approval of the Planning and Zoning Commission. The Planning and Zoning Commission may allow for such exceptions where it is demonstrated that such plantings will not be a detriment to adjoining streets, other nearby property or the trees thereon.
d.

4. 
Minimum distance between street and sidewalk. In no event shall a tree be planted where the clear space between the curb and a sidewalk is less than four feet, except where authorized by the Director of Public Works or his/her designated representative. Where there is space between the curb, or edge of pavement, and sidewalk of not less than four feet, street trees may be planted. Such street trees shall be placed midway between the curb, or edge of pavement, and sidewalk wherever practical.
5. 
Street trees between street and sidewalk-medium canopy. Where the planting area between the curb or edge of the roadway pavement and the edge of a sidewalk is limited to a width of between four and five feet, only medium canopy trees shall be planted, except as provided for in Subsection 8 below.
6. 
Street trees between street and sidewalk-large or medium canopy. Where the planting area between the curb or edge of the roadway pavement and the edge of the sidewalk is greater than five feet, medium and/or large canopy trees shall be planted, except as provided for in Subsection 8 below.
7. 
Street trees where no sidewalk exists. On parcels of land where no sidewalk exists, the required canopy trees shall be planted in an area not more than four feet nor less than three feet from the back of the curb or the edge of street pavement.
8. 
Interference with overhead utility wires. In instances where canopy trees of either medium or large size are likely to cause interference with overhead utility wires (as determined by the Director of Public Works or his/her designated representative), understory trees may be acceptable for planting.
9. 
Tree plantings prohibited near public right-of-way. No tree of any type shall be planted on private or public property within five feet of the right-of-way of any public street.
g. 
Required landscaping along side lot lines. Except as otherwise provided for in these regulations, landscape plantings of at least five feet in width shall be required along each side lot line. The same shall apply to rear lot lines of corner lots, between the street and the established building setback line.

1. 
For any parking area containing more than five spaces, a minimum of 20 square feet of interior landscaped area shall be provided within the parking lot for each parking space. Landscape areas shall be uniformly distributed in one or more areas so as to break up the apparent expanse of the paved parking areas. In order to qualify as interior landscaped area, such area shall be located wholly within or projecting inward from the perimeter of the parking area the landscaped strip, as required under subsection a.1 above, shall not qualify as interior landscaped area. This requirement may be waived by the Planning and Zoning Commission if the Commission determines that there is not sufficient parking space available.
2. 
There shall be a minimum of one planting island, within and up to every 100 linear feet of parking for each parking row. This requirement may be waived by the Planning and Zoning Commission if the Commission determines that there is not sufficient parking space to meet such a requirement. Such islands shall be spaced evenly wherever possible and the ends of parking rows abutting a circulation aisle shall be defined by a planting island wherever feasible. These planting island areas shall be protected from vehicular encroachment by nonmountable, reinforced concrete curbing of a type specified by the Director of Public Works. The use of unreinforced extruded curbing of asphalt or other materials is prohibited.
3. 
Planting islands shall generally not be less than 90 square feet in area and eight feet wide, as measured from back of curb to back of curb.
4. 
In instances where vehicle parking occurs perpendicular or parallel to parking islands, no landscape plantings, other than low profit ground cover (grass, ivy, creeping juniper, wood mulch, or similar materials), shall be installed within 42 inches of the back of the curb.
5.

If the area where the tree is removed is to be paved, the top of the stump shall be ground out to at least six inches below the ground level.
(5) 
Required replacement of trees. Any existing trees or vegetation that satisfy the requirements of this division which are removed shall be replaced with plantings which are of acceptable type and species and in locations which comply with the provisions of this division and any previously approved site and landscape plan. Such replacement shall take place within six months of notification from the Director of Public Works, or the Director's designated representative. Where such replacement involves properties within a C-1 or M-1 district, a landscape plan shall not be required if the replacement plantings match a previously approved landscape plan. If replacement will significantly vary from an approved landscape plan, a new plan may be required.
(6) 
Pruning. All pruning should be accomplished according to standard horticultural practices.
Trees may be periodically pruned or thinned in order to reduce the leaf mass and thus increase visibility to the site and/or minimize damage from storms. Trees severely damaged by storms or other causes, or trees under utility wires or other obstructions where standard horticultural pruning practices are impractical, may be exempted from this prohibition at the determination of the Director of Public Works, or the Director's designated representative.
