(A) Table 19.33.007(1)
shall be used to determine the minimum amounts of woodland canopy that must be retained during site modification or maintenance on any parcel:
Canopy Retention Standard Shall Be the Greater of Column a or Column B: | ||
Baseline Canopy Cover (1) | Column A (2) | Column B (2) |
Canopy Retention Standard Shall Be the Greater of Column a or Column B: | ||
Baseline Canopy Cover (1) | Column A (2) | Column B (2) |
80-100% | .75 x baseline canopy cover | 65% canopy covert |
60-79% | .80 x baseline canopy cover | 51% canopy cover |
40-59% | .85 x baseline canopy cover | 36% canopy cover |
20-39% | .90 x baseline canopy cover | 19% canopy cover |
19% or less | 1.0 x baseline canopy cover | — |
(B) Individual trees and or massed individual trees shall be included in the calculation of canopy retention standard. Example: For 50% baseline canopy, the minimum allowable canopy after modification and maintenance would be the greater of Column A, (0.85 times 50% equals 42.5% canopy) or Column B, (36% canopy). In this example, the minimum allowable canopy after modification and maintenance would be 42.5%. Pursuant to § 19.33.005, if the canopy is located on a slope of 30% or greater the canopy retention area (the percentage of removal of individual and/or masses of woodland trees is equal to the baseline percentage of the canopy retention percentage in this table subtracted from 100%) must be increased by a factor of 50%.
(C) Canopy retention standard shall be applied to retain undisturbed woodlands as a priority over retention of individual trees. No more than 10% of the canopy retention standard may be met by individual trees not included within designated woodlands.
