Development shall be landscaped, screened, and buffered in accordance with Tables 1-3 on the following page.
The planting and buffer yard requirements are applied to new development and multifamily and nonresidential expansions. In some instances, partial compliance is acceptable. Consult the Zoning Ordinance or contact Development Services to determine whether and to what extent these requirements must be met for a specific project.
The screening requirements must be met for all multifamily and nonresidential new construction, expansions, or changes in use, as well as whenever new trash receptacles or mechanical equipment is installed outside.
Trees used to satisfy parking lot landscape requirements do not count toward other requirements.
All plantings shall meet the planting standards and landscape specifications in Section 4.
Table 1: Planting Requirements
Table 2: Screening Requirements
Table 3: Buffer Yard Requirements
(Ord. No. O2025-15, § 1, 4-22-25)
Landscaping and screening shall be designed, installed, and maintained according to the guidelines provided herein. Minimum requirements are determined by land use and zoning district as specified in Section 3 above.
Where possible, applicants shall satisfy all requirements with native and adaptive plant material. Refer to Section 8 of this manual for Preferred Native and Adaptive Plant Materials.
Part 1. Landscape Specifications
L3: Trees - woody perennial plants, typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance above the ground. Installed for shade, buffering, aesthetic, or other purposes. To be provided in appropriate quantity and proportion as described herein. Required trees shall be selected from the Preferred Plant List in this manual and shall be no less than three-inch caliper at the time of planting. Refer to Landscape Requirements table for specific requirements and Preferred Native and Adaptive Plant Materials for approved plant materials.
L2: Shrubs and Ornamental Ground Covers - L2 landscape shall be selected from the evergreen shrub, perennial or seasonal flowering plant, or ornamental grass species on the Preferred Plant List in this manual. Shrubs include woody plant material smaller than a tree with several stems rising at or near the ground, installed for buffering, aesthetic, or other purposes. Ornamental ground covers include low growing, spreading plants, ornamental grasses covering open soil for aesthetic, storm water management, or other purposes. At least two species shall be selected for each 20 plants required. Refer to Landscape Requirements table for specific requirements and Preferred Plant List for approved plant materials.
L1: Supplemental Landscape - L1 treatments may include approved L2 ground cover or shrubs, lawn, mulch, bark, decorative rock, outdoor furniture, art installations, and other landscape or hardscape features, and shall present a finished, orderly appearance and reasonably complete coverage of the landscape area. Creativity in combining multiple, complementary elements is encouraged. Except as approved by the Planning Director all landscape areas shall have a minimum area of 200 square feet with a minimum horizontal dimension of seven feet, measured in any direction.
Part 2. Screening Specifications
Applies to all new multifamily and nonresidential construction and expansions, change in use on property zoned for nonresidential uses, installation of exterior mechanical equipment. See section 12-5-5(b)(2).
S1: Low Screening - A screen installed for limited sight-obstruction or access control purposes. S1 shall be shrubs, landscape berm, or other plants with minimum height of three feet zero inches, except that screening around parking lots in streetscape areas may be a masonry wall with a height of three feet zero inches to four feet zero inches in height consistent with the architecture of the main building or within a coherent hardscape theme.
S2: High Screening - A screen installed to eliminate clear sight lines between areas with minimal breaks where necessary for controlled access and to maintain required visibility triangles.
S2 screening shall include a berm or fencing such as wood, masonry, or other materials as approved by the planning director, along with evergreen shrubs densely planted so as to form a solid hedge or living wall.
S3: Equipment Screening - A screen installed to eliminate clear sight lines to any mechanical equipment, trash bins, loading areas, or storage areas on all sides. Screening shall be a solid plane which is architecturally consistent with the structure on or adjacent to which it is installed. Screening materials at ground level shall be masonry wall or wood fence material or a combination of the two in keeping with the architectural style of the development.
Screening of rooftop equipment shall be sufficient to conceal all such equipment entirely when viewed from any vantage point at the same or lower elevation and shall be provided with a parapet wall for new construction. A parapet wall or architecturally compatible solid materials will be considered for the addition of new equipment on existing rooftops.
Part 3. Parking Lot Landscape Specifications
Canopy trees shall be preserved or planted according to the schedule in Section 3 using a combination of interior or endcap islands or divider medians depending on lot dimensions, number of spaces, other site considerations, and the following parking lot landscape specifications.
Islands with two canopy trees and two ornamental trees shall be provided every 150 linear feet of parking area, including any combination of parking stalls, rows, and drive aisles. Island dimensions shall equal four parking spaces. For example, an island adjacent to 90-degree parking spaces will measure 18 feet wide, 36 feet long, and 648 square feet, as shown at right.
Divider medians shall be provided every four drive aisles, have a minimum width of ten feet, and provide canopy trees every 20 feet on center.
Part 4. Credits and Substitutions
The Planning Director may approve credits against the requirements above or allow substitutions for certain plantings to incentivize preservation of existing trees or to facilitate creativity or flexibility on challenging or unique sites. A landscape plan is required whenever credits or substitutions are applied.
The preservation of healthy, mature trees is strongly encouraged. Qualifying trees preserved during development will receive credit against L3 tree planting requirements and, for multifamily and nonresidential uses, against total landscape area requirements. In order to qualify, trees shall meet all of the following criteria:
(1)
The tree is not a nuisance species.
(2)
The tree is a minimum six-inch DBH.
(3)
The tree is located on the subject property, within 75 feet of the public right-of-way.
(4)
The tree meets all planting requirements of this manual.
(5)
The tree is healthy and protected from direct and indirect root damage and truck and crown disturbance prior to, during, and following development.
Table 4: Credit for Preservation of Existing Trees
Minimum parking requirements for multifamily and nonresidential uses may be reduced by ten percent when the minimum L2 and L3 planting requirements are exceeded by at least 15 percent. This may include the preservation of native or adapted ground covers on unimproved (prairie) portions of lots when an inventory of the plants is provided on the landscape plan.
Substitutions are subject to approval by the planning director and may only be applied in the specific situations described:
(1)
Canopy trees may be substituted for shrubs at the rate of one canopy tree for five L2 plants when a cohesive landscape design provides trees exceeding the L3 requirements.
(2)
Ornamental trees may be substituted for shrubs at the rate of one ornamental tree for three L2 plants when a cohesive landscape design provides trees exceeding the L3 requirements.
(3)
Ornamental trees may be substituted for canopy trees at the rate of two ornamental trees for every canopy tree when an overhead utility line prevents planting a canopy tree within a required buffer yard or area where S2 screening is required.

(Ord. No. O2025-15, § 1, 4-22-25)
Landscaping and screening shall be designed, installed, and maintained according to the guidelines provided herein. Minimum requirements are determined by land use and zoning district as specified in Section 3 above.
Where possible, applicants shall satisfy all requirements with native and adaptive plant material. Refer to Section 8 of this manual for Preferred Native and Adaptive Plant Materials.
Part 1. Landscape Specifications
L3: Trees - woody perennial plants, typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance above the ground. Installed for shade, buffering, aesthetic, or other purposes. To be provided in appropriate quantity and proportion as described herein. Required trees shall be selected from the Preferred Plant List in this manual and shall be no less than three-inch caliper at the time of planting. Refer to Landscape Requirements table for specific requirements and Preferred Native and Adaptive Plant Materials for approved plant materials.
L2: Shrubs and Ornamental Ground Covers - L2 landscape shall be selected from the evergreen shrub, perennial or seasonal flowering plant, or ornamental grass species on the Preferred Plant List in this manual. Shrubs include woody plant material smaller than a tree with several stems rising at or near the ground, installed for buffering, aesthetic, or other purposes. Ornamental ground covers include low growing, spreading plants, ornamental grasses covering open soil for aesthetic, storm water management, or other purposes. At least two species shall be selected for each 20 plants required. Refer to Landscape Requirements table for specific requirements and Preferred Plant List for approved plant materials.
L1: Supplemental Landscape - L1 treatments may include approved L2 ground cover or shrubs, lawn, mulch, bark, decorative rock, outdoor furniture, art installations, and other landscape or hardscape features, and shall present a finished, orderly appearance and reasonably complete coverage of the landscape area. Creativity in combining multiple, complementary elements is encouraged. Except as approved by the Planning Director all landscape areas shall have a minimum area of 200 square feet with a minimum horizontal dimension of seven feet, measured in any direction.
Part 2. Screening Specifications
Applies to all new multifamily and nonresidential construction and expansions, change in use on property zoned for nonresidential uses, installation of exterior mechanical equipment. See section 12-5-5(b)(2).
S1: Low Screening - A screen installed for limited sight-obstruction or access control purposes. S1 shall be shrubs, landscape berm, or other plants with minimum height of three feet zero inches, except that screening around parking lots in streetscape areas may be a masonry wall with a height of three feet zero inches to four feet zero inches in height consistent with the architecture of the main building or within a coherent hardscape theme.
S2: High Screening - A screen installed to eliminate clear sight lines between areas with minimal breaks where necessary for controlled access and to maintain required visibility triangles.
S2 screening shall include a berm or fencing such as wood, masonry, or other materials as approved by the planning director, along with evergreen shrubs densely planted so as to form a solid hedge or living wall.
S3: Equipment Screening - A screen installed to eliminate clear sight lines to any mechanical equipment, trash bins, loading areas, or storage areas on all sides. Screening shall be a solid plane which is architecturally consistent with the structure on or adjacent to which it is installed. Screening materials at ground level shall be masonry wall or wood fence material or a combination of the two in keeping with the architectural style of the development.
Screening of rooftop equipment shall be sufficient to conceal all such equipment entirely when viewed from any vantage point at the same or lower elevation and shall be provided with a parapet wall for new construction. A parapet wall or architecturally compatible solid materials will be considered for the addition of new equipment on existing rooftops.
Part 3. Parking Lot Landscape Specifications
Canopy trees shall be preserved or planted according to the schedule in Section 3 using a combination of interior or endcap islands or divider medians depending on lot dimensions, number of spaces, other site considerations, and the following parking lot landscape specifications.
Islands with two canopy trees and two ornamental trees shall be provided every 150 linear feet of parking area, including any combination of parking stalls, rows, and drive aisles. Island dimensions shall equal four parking spaces. For example, an island adjacent to 90-degree parking spaces will measure 18 feet wide, 36 feet long, and 648 square feet, as shown at right.
Divider medians shall be provided every four drive aisles, have a minimum width of ten feet, and provide canopy trees every 20 feet on center.
Part 4. Credits and Substitutions
The Planning Director may approve credits against the requirements above or allow substitutions for certain plantings to incentivize preservation of existing trees or to facilitate creativity or flexibility on challenging or unique sites. A landscape plan is required whenever credits or substitutions are applied.
The preservation of healthy, mature trees is strongly encouraged. Qualifying trees preserved during development will receive credit against L3 tree planting requirements and, for multifamily and nonresidential uses, against total landscape area requirements. In order to qualify, trees shall meet all of the following criteria:
(1)
The tree is not a nuisance species.
(2)
The tree is a minimum six-inch DBH.
