    g.    Existing and proposed impervious surfaces;

    h.    Identification of a contact person and/or arborist who will be responsible for implementing and maintaining the approved tree protection plan; and

    i.    Location and type of tree protection measures to be installed per subsection of this section.

    3.    For development requiring a planning action, the tree preservation plan shall include an inventory of all trees on-site, their health or hazard condition, and recommendations for treatment for each tree.

    B.    Tree Protection Measures Required.

    1.    Except as otherwise determined by the tree permit administrator, all required tree protection measures set forth in this section shall be instituted prior to any development activities, including, but not limited to, clearing, grading, excavation or demolition work, and shall be removed only after completion of all construction activity, including landscaping and irrigation installation.

    2.    Fencing, a minimum of six feet tall with posts placed no farther than ten feet apart, shall be installed at the edge of the tree protection zone or drip line, whichever is greater, and at the boundary of any open space tracts, riparian areas, or conservation easements that abut the parcel being developed.

    3.    The fencing shall be flush with the initial undisturbed grade.

    4.    Approved signs shall be attached to the fencing stating that inside the fencing is a tree protection zone, not to be disturbed unless prior approval has been obtained from the tree permit administrator for the project.

    5.    No construction activity shall occur within the tree protection zone, including, but not limited to, dumping or storage of materials such as building supplies, soil, waste items, equipment, or parked vehicles.

    6.    The tree protection zone shall remain free of chemically injurious materials and liquids such as paints, thinners, cleaning solutions, petroleum products, and concrete or dry wall excess, construction debris, or run-off.

    7.    No excavation, trenching, grading, root pruning or other activity shall occur within the tree protection zone unless approved by the tree permit administrator.

    C.    Inspection. The applicant shall not proceed with any construction activity, except installation of erosion control measures, until the city has inspected and approved the installation of the required tree protection measures and a building and/or grading permit has been issued by the city.
