Existing trees meeting the requirements of section 1232 may be counted and shall be credited toward meeting the minimum tree density requirements
of this division. Only existing trees with a dbh of two inches or greater shall be
counted in determining tree density units. Table 12-2 shall apply and shall be used to determine the value of existing trees. Actual tree
diameters or calipers are to be rounded to the nearest whole number for the calculation
of tree unit values (e.g., 4.5 = 5). Where table 12-2 does not provide a value for the size of an existing tree based on size, interpolation
between the lower and higher size trees provided in table 12-2 shall be used to determine the tree value.
