Braided remains of the exposed roots shall not be left dangling. Roots shall be cleanly pruned back to 1 to 2 inches of the soil line. If trimming of larger roots is unavoidable, they shall be cleanly cut 5. Natural grade around oak trees shall be maintained, especially within the drip line. Construction of cut and fill slopes or sawed. If there is a lateral root, the cut shall be made outside the lateral root, if possible. along the limit of grading that may result in soil erosion and damage to the oaks along these north facing slopes, shall be mitigated with appropriate erosion control measures. e. All exposed roots shall be covered with wet burlap (or a suitable substitute) and kept moist until the soil is returned. 6. Disturbed areas shall be stabilized as much as possible with vegetative cover. If slopes cannot be stabilized solely with bio-engineering techniques, construction of retaining walls may be necessary for the proposed cut and fill areas. f. All topsoil removed during trenching shall be stockpiled in an orderly fashion so that it can be replaced after the utilities have been installed (as it was removed) and tamped down in the some relative soil profile. 7. Machinery, autos, trucks and other equipment shall not be parked or driven under any oak trees during the development and/or construction phases of the development. g. After the trench is filled, the area under the dripline shall be irrigated so that water penetrates down to the depth of the bottom of the trench. Project Information 8.

Drainage facilities shall be designed to eliminate i. No significant change in drainage around the oak trees as a result of the trenching shall occur.

If trenches must be dug under oak trees, every effort shall be made to California Department of Forestry (CDF) standards, shall be avoided. In all cases, pruning shall be kept to a minimum install all pipes in one trench, rather than multiple trenches. If a significant section of the root system is disrupted, and monitored by a qualified arborist and/or landscape architect with knowledge of native oaks and proper pruning careful pruning of a proportional number of branches may reduce the impact. All pruning shall be conducted under procedures. p g p p y p p g Drawing Package the supervision of a certified arborist and/or landscape architect.

Any and all landscape plans for this development shall preclude irrigation and/or irrigated plantings within the established tree protection zones and/or the drip lines of the oak woodlands. a. Trenching in the root zone should and will be avoided if possible. One good alternative to trenching is to place utilities in a conduit that is bored or tunneled through the soil.
