Exhibit B <br />ORDINANCE Exhibit A - Page 23 of 66 <br />19.37.140 SETBACKS, FENCING, SIGNS, AND OTHER PROTECTIVE MEASURES <br />A. General Requirements. Storage of building materials, junk and other items is not permitted within <br />critical areas or buffers. All construction staging areas must be shown on approved plans and be located <br />outside of critical areas and buffers. <br />B. Setbacks from Buffers. To maintain the integrity of the buffer, principal buildings shall be set back a <br />minimum of ten feet from the edges of all critical area buffer boundaries. All other structures and <br />improvements shall maintain a setback of five feet from the edge of the buffer. <br />C. Fencing and Other Protection Mechanisms. Except for utility and road projects, the city shall require <br />that any development proposed on a lot which contains or adjoins a critical area provide a fence or <br />other structural protection along the outer edge of a buffer to minimize encroachment and disturbance. <br />Fencing shall be split-rail or an alternative approved by the planning director. Fencing must be installed <br />in a manner that allows continuous wildlife movement. <br />D. Signs. The city may require the applicant to provide informational signs in conspicuous locations <br />approximately 50 feet apart on a fence marking the buffer to identify the importance of maintaining <br />the critical area and buffer in a clean and undisturbed condition. Such signs shall meet the requirements <br />for incidental signs as specified in Chapter 19.36. <br />E. Protection of Significant Trees within Buffers (Evergreens at Least Eight-Inch Diameter at Breast <br />Height). If Heritage Trees and evergreen trees at least eight-inch diameter at breast height are <br />identified on the outer edge of the buffer such that their drip line extends beyond the buffer edge, the <br />following tree protection requirements must be followed: <br />1. A tree protection area shall be designed to protect each tree or tree stand during site <br />development and construction. Tree protection areas may vary widely in shape, but must <br />extend a minimum of five feet beyond the existing tree canopy area along the outer edge of the <br />drip line of the tree(s), unless otherwise approved by the department. <br />2. Tree protection areas shall be added and clearly labeled on all applicable site development <br />and construction drawings submitted to the department. <br />3. Temporary construction fencing at least thirty inches tall shall be erected around the <br />perimeter of the tree protection areas prior to the initiation of any clearing or grading. The <br />fencing shall be posted with signage clearly identifying the tree protection area. The fencing <br />shall remain in place through site development and construction. <br />4. No clearing, grading, filling or other development activities shall occur within the tree <br />protection area, except where approved in advance by the department and shown on the <br />approved plans for the proposal. <br />5. No vehicles, construction materials, fuel, or other materials shall be placed in tree protection <br />areas. Movement of any vehicles within tree protection areas shall be prohibited. <br />6. No nails, rope, cable, signs, or fencing shall be attached to any tree proposed for retention.
