Exhibit B <br />ORDINANCE Exhibit A - Page 52 of 55 <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 habitat corridors along critical fish and wildlife areas. <br />D. Signs. The city may require the applicant to provide informational signs in conspicuous locations on <br />the fence or near the wetland to identify the wetland as a critical area and the importance of <br />maintaining it in a clean and undisturbed condition. Such signs shall meet the requirements for <br />incidental signs as specified in Chapter 19.36. <br />E. Protection of Significant Trees within Buffers (Heritage Trees and Evergreens at Least Eight-Inch <br />Diameter at Breast Height). If trees are identified on the outer edge of the buffer such that their drip <br />line extends beyond the buffer edge, the 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. <br />7. The department may approve the use of alternate tree protection techniques if an equal or <br />greater level of protection will be provided. <br />F. Critical Area Covenants. Except as provided for below, the city shall require that all features classified <br />as critical areas by this chapter and their buffers, including fish and wildlife habitat conservation areas, <br />be placed in critical area protective covenants. Covenants shall not be required for: <br />1. Utility and road projects in public rights-of-way.
