Figure 245-122A: Sample Landscaping Schemes |
Alternative A: Best suited for building foundations. 750 landscaping points: 20 medium trees 15 small shrubs 60 shrubs |
Alternative B: Best suited for developed lots. 1,250 landscaping points: 6 climax trees 8 small trees 20 medium trees 41 evergreen plantings |
Alternative C: Best suited for street frontages. | |
Option 1. 280 landscaping points: 2 climax trees 2 tall trees 2 small trees | Option 2. 280 landscaping points: 2 climax trees 2 tall trees 4 small trees 8 evergreen shrubs |
Alternative D: Best suited for paved areas. | |
Option 1.68 880 landscaping points: 2 climax trees 13 tall trees 68 evergreen shrubs | Option 2. 880 landscaping points: 5 climax trees 6 tall trees 68 evergreen shrubs |
Landscaping calculation equations for this example: |
Paved area = (P1 x P2) + (P3 x P4) + (P5 x P6) + (P7 x P8) + (P9 x P10) |
Street frontage = S1 + S2 |
Building perimeter = F1 + F2 + F3 + F4 + F5 + F6 + F7 + F8 |
Building floor area = (B1 x B2) + (B3 x B4) + (B5 x B6) |

Landscaping Components | |||||
Building Foundation | Street Frontages | Paved Areas | Developed Lots | ||
Types of Landscaping | Climax trees and tall trees shall not be used to meet this requirement | Shrubs not allowed; a minimum of 50% of points from climax or tall trees and 30% from medium trees | A minimum of 30% of points climax/tall trees and 40% from shrubs | All plant categories can be used for this requirement | |
Placement of Landscaping | Located so that at maturity the plant's drip line is located within 10 feet of building foundation | Located within 10 feet of the public right-of-way | Within paved area or within 10 feet of paved area | Located away from areas that meet other landscaping requirements | |
Calculation of Landscaping Points | Points per 100 feet of building foundation | Points per 100 linear feet of street frontage | Greater of: points per 20 parking stalls or 10,000 square feet of paved area | Points per 1,000 square feet of total building footprints | |
