1. All trees and natural areas shown on plan to be preserved shall be protected during construction with temporary fencing. 2. Protective fences shall be erected according to City of Austin Standards for Tree Protection. 3. Protective fences shall be installed prior to the start of any site preparation work (clearing, grubbing or grading), and shall be maintained throughout all phases of the construction project. 4. Erosion and sedimentation control barriers shall be installed or maintained in a manner which does not result in soil build-up within tree drip lines. 5. Protective fences shall surround the trees or group of trees, and will be located at the outermost limit of branches (drip line) , for natural areas, protective fences shall follow the Limit of Construction line, in order to prevent the following: A. Soil compaction in the root zone area resulting from vehicular traffic or storage of equipment or materials; B. Root zone disturbances due to grade changes (greater than 6 inches cut or fill), or trenching not reviewed and authorized by the City Aborist; C. Wounds to exposed roots, trunk or limbs by mechanical equipment; D. Other activities detrimental to trees such as chemical storage, cement truck cleaning, and fires. 6. Exceptions to installing fences at tree drip lines may be permitted in the following cases: A. Where there is to be an approved grade change, impermeable paving surface, tree well, or other such site development, erect the fence approximately 2 to 4 feet beyond the area disturbed; B. Where permeable paving is to be installed within a tree's drip line, erect the fence at the outer limits of the permeable paving area (prior to site grading so that this area is graded separately prior to paving installation to minimized root damage); C. Where trees are close to proposed buildings, erect the fence to allow 6 to 10 feet of work space between the fence and the building; D. Where there are severe space constraints due to tract size, or other special requirements, contact the City Arborist at 974-1876 to discuss alternatives. Special Note: For the protection of natural areas, no exceptions to installing fences at the Limit of Construction line will be permitted. 7. Where any of the above exceptions result in a fence being closer than 4 feet to a tree trunk, protect the trunk with strapped-on planking to a height of 8 ft (or to the limits of lower branching) in addition to the reduced fencing provided. 8. Trees approved for removal shall be removed in a manner which does not impact trees to be preserved. 9. Any roots exposed by construction activity shall be pruned flush with the soil. Backfill root areas with good quality top soil as soon as possible. If exposed root areas are not backfilled within 2 days, cover them with organic material in a manner which reduces soil temperature and minimizes water loss due to evaporation. 10. Any trenching required for the installation of landscape irrigation shall be placed as far from existing tree trunks as possible. 11. No landscape topsoil dressing greater than 4 inches shall be permitted within the drip line of trees. No soil is permitted on the root flare of any tree. 12. Pruning to provide clearance for structures, vehicular traffic and equipment shall take place before damage occurs (ripping of branches, etc.). 13. All finished pruning shall be done according to recognized, approved standards of the industry (Reference the National Arborist Association Pruning Standards for Shade Trees available on request from the City Arborist). 14. The contractor shall install erosion/sedimentation controls and tree protective fencing prior to any site preparation work. 15. The contractor shall inspect the controls and fences at weekly intervals and after significant rainfall events to insure that they are functioning properly. Damaged controls and fencing shall be replaced. Silt accumulation at controls must be removed when depth reaches six inches. NOTE:: WITHIN THE 28" CEDAR, 24" PECAN, 25" PECAN & 30" PECAN CRZ, THE AREA BETWEEN THE FIRST FLOOR SLAB, THE NATURAL GRADE AND GROUND COVER IS TO BE PRESERVED. NO STORAGE OF MATERIALS AND HEAVY EQUIPMENT IN THIS AREA. PROVIDE TREE PROTECTION AS REQUIRED BY CODE AND DESCRIBED IN THE TREE PROTECTION NOTES. R E D ARC ST E N C.
