"Commercial wood cutting"means cutting trees for fuelwood purposes producing in excess of two cords (256 ft.) of wood for sale or profit in any one-year period.
"County arborist"means a person employed by or chosen and retained by the county to review, evaluate and prepare reports and requests to remove and/or relocate protected trees. In performing his or her duties and responsibilities, the county arborist may conduct field inspections independently or in the company of county employees and/or other arborists.
"Cutting"means the detaching or separating of any limb, branch or root from a tree.
"Dead tree"means a tree that does not contain any live tissue, i.e., green leaves or live limbs.
"Deadwood"means limbs or branches that contain no green leaves or live limbs.
"Development activity"means any activity within the protected zone of a tree, which could impact the health of a tree or landmark tree, including, but not limited to, cutting, grading, irrigating and trenching.
"Diameter at breast height"means the diameter of a tree measured at four and one-half feet above ground level on the high side of the tree. The diameter may be calculated by use of the following formula: DBH = circumference at breast height divided by 3.142.
"Discretionary project"means any nonministerial development project that must be approved by either the: board of supervisors, planning commission, parcel review committee, design/site review committee or zoning administrator. Discretionary projects include, but are not limited to: conditional use permits, parcel maps, rezoning, design reviews, subdivision maps, or variances. (Discretionary projects do not include issuance of building permits, business licenses, or similar ministerial actions.)
"Drip line"means the outermost edge of a tree's canopy as measured at the time of application for a tree permit. When depicted on a map, the dripline will appear as an irregular-shaped circle that follows the contour of the tree's branches as seen from overhead.
"Dying/unhealthy tree"means any tree certified by an arborist or registered professional forester as being unhealthy or dying.
"Encroachment"means any development activity conducted within the protected zone of a protected or preserved tree.
"Grading"means the movement of any soil or earth material within the protected zone or protected or preserved trees.
"Irrigation"means transfer of water to a site by artificial means.
"Landmark tree"means a tree or grove of trees designated by resolution of the board of supervisors to be of historical or cultural value, an outstanding specimen, an unusual species and/or of significant community benefit. Notwithstanding any other provision of this section, a tree that is not native to California may be designated as a landmark tree. (Note: A list of culturally significant or landmark trees [i.e., palms, along English Colony Road, oak canopy tree areas, Deodar cedars on Highway 49, major heritage oak trees, etc.] shall be prepared by the county parks division as a beginning list of "Landmark Trees.")
"Minor tree permit"means an authorization by the planning services division authorizing specifically identified work or development activities to be performed within the protected zone of a protected tree. (Note: Minor tree permits are only issued for single family residential lots and other specific projects as determined by the planning director. For discretionary projects, approval or denial of tree removal is part of that discretionary action.)
"Oak tree information packet"means a package containing certain documents which must be distributed to property owners whose lots contain native oak trees.
"Preserved tree"means a tree that has been established as one to be saved through the tree permit or discretionary project approval process.
"Protected tree"means any tree, including a landmark tree, for which a tree permit is required prior to any removal or development activity being conducted within the protected zone.
"Protected zone"means a circle, the radius of which is equal to the largest radius of a protected tree's dripline plus one foot.
"Public land"means all land owned or controlled by public entity.
"Removal"means the physical removal of a tree.
"Riparian zone"means any area within 50 feet from the centerline of a seasonal creek or stream, any area 100 feet from the centerline of a year round creek, stream, or river, and any area within 100 feet from the shoreline of a pond, lake or reservoir. At a minimum all streams, creeks, ponds, lakes, and reservoirs as shown on 7.5-minute USGS maps are included in this definition. (A riparian zone established in a specific community or the general plan may supersede this definition.) (Note: All trees regardless of size within riparian areas within the tree preservation zones and as a part of any discretionary project county-wide are subject to this article.) For any project included within the PCCP boundary (see Section
19.10.050 of this article) the term "riparian zone" is to be replaced by the definitions for "stream system" and "aquatic resources of Placer County" found in Section
19.10.040. The application of the riparian zone standards found in this article will not apply to projects within the PCCP boundary, and instead the conditions and mitigation requirements found in Chapter 6 of the HCP/NCCP (Conditions on Covered Activities) and Chapter 6 of the CARP shall apply (Avoidance, Minimization and Mitigation Requirements).
"Routine maintenance"means actions taken for the continued health of a protected tree including, but not limited to: deadwooding, mowing grass close to a tree, and application of insecticides and pesticides.
"Site planning meeting"means an on-site meeting with the owners, developer and his or her contractors, and/or engineers; the arborist; and county representatives to delineate special procedures, limits of work, lines of authority and special conditions or procedures not specifically covered by the Placer County Code.
"Tree"means a tall woody plant native to California, with a single main stem or trunk at least six inches dbh, or a multiple trunk with an aggregate of at least 10 inches dbh. For all oak species (Quercus sp.) the woody plant will be considered a tree when the single main stem is five inches dbh or larger. (Note: Foothill pines are exempt from this article. Also, see "riparian zone" definition.) Certain plants which are more commonly found as "brush," such as manzanita, are not considered to be a tree in this article regardless of size.
