Josephine Woods Tree Preservat t D February 24, 2011 4. Quantified. and identified all non- exempt significant and heritage significant tree removals and preservation areas. 5. Quantified. resulting removal percentages of significant and heritage significant tree removals using NET D�BH-inch totals. 6. Quantified. allowable significant and heritage significant tree NET DBH-inch removal totals. 7. Quantified. excess/replacement requirement for both the significant and heritage significant trees using the 0.5-inch and 2-inch per DBH-inch removed replacement criteria. 8. Quantified. the heritage significant tree savings credit using the 2-inch per DBH-inch saved. criteria. 9. Quantified. resultant tree replacement requirement to determine if additional replacement was required. Tree Preservation Calculation Summary Total heritage significant tree DBH-inch = Total significant tree DBH-inch (minus heritage DBH Quantity) Total heritage significant tree removal DBH-inch Total significant tree removal DBH-inch = Allowable heritage significant tree removal DBH-inch Allowable significant tree removal DBH-inch = Excess heritage significant tree removal DBH-inch Excess significant tree removal DBH-inch = Replacement heritage significant tree removal DBH-inch = 2*89 Replacement significant tree removal DBH-inch = 0.5*585 Total replacement requirement DBH-inch = Heritage significant tree saving credit DBH-inch = 2*288 Additional tree planting credit DBH-inch Total replacement credit DBH-inch = 443 61062 155(35.0%) 21707 (44.7%) 66(15%) 21122(35%) 89 585 177 293 470 576 0 106* *Credit for saving heritage significant trees and additional plantings exceeds the replacement requirement therefore no additional restitution/replacement is required. Heritage Tree Saving Summary Notes: * Tree 4 1220- (36" Red. Oak[ ■ Road. alignment was kept southerly to avoid. tree. ■ Road. grade/profile elevation was en, ineered. to match grade in area of tree. ■ Aqjacent house pad. elevation was desi, ned. to avoid. grading in the tree area. ■ House pad. was shifted. to east side of lot against setback to avoid. tree. ■ Driveway was switched. to low side of lot to avoid. tree. * Tree 4 1239- (32" Red. Oak[ Road. grade/profile elevation was desi, ned. to ensure the adjacent house pad. elevation could. be set at an elevation to avoid. disturbance to tree. Pond. was shifted. to the east to avoid. need. for grading in area of tree. Area has been left relatively undisturbed. other than the grading of a small swale to drain area near tree 4 1 341 which will allow for the saving of that tree. Tree 4 1274 (39" Red. Of ak) ■ Road. grade/profile elevation was en, ineered. to match grade in area of tree. gjacent house pad. elevation was desi, ned. to avoid. grading in the tree area.
