COBSON <br /> �� CONSULTING ENGINEERS <br /> The wetland that this project discharges to is just south of the grass play field, there <br /> are no encroachments into native vegetation connecting the wetland and other <br /> contiguous areas of native vegetation by this project. <br /> d. Avoid compaction of soil and introduction of invasive plant or animal species in <br /> the wetland and its buffer. <br /> Avoidance of invasive plan or animal species will pursued with this project <br /> e. Take measures to avoid general physical impacts (e.g., littering and vegetation <br /> destruction). Examples are protecting existing buffer zones; discouraging access, <br /> especially by vehicles, by planting outside the wetland, and encouragement of <br /> stewardship and signage by landowners. <br /> The project will protect and not encroach into undeveloped buffer areas of the <br /> existing wetland. <br /> f. Any stormwater management practices, such as Runoff Treatment or Flow Control <br /> BMP implementation, must be done outside of the wetland buffer boundary, <br /> except limited circumstances where the wetland and/or buffer may be used for <br /> additional Runoff Treatment and/or Flow Control of stormwater(See I-C.6 <br /> Compensatory Mitigation of Wetlands) <br /> This project will not construct or implement runoff treatment or flow control BMPs <br /> within the wetland buffer. <br /> g. Discharge from a BMP or project site should be dispersed using a method to <br /> diffuse the flow before entering the wetland buffer. <br /> The existing discharge pipe into the wetland will be used to maintain existing flows <br /> into the wetland. <br /> h. Consider fences to restrict human access, but make sure it doesn't interfere with <br /> wildlife movement. They should be used when wildlife passage is not a major <br /> issue and the potential for intrusive impacts is high. When wildlife movement and <br /> intrusion are both issues, the circumstances will have to be weighed to make a <br /> decision about fencing. Check with the local and/or state agencies to determine if <br /> fencing would be allowed. <br /> Existing fences are already in place and will be maintained. <br /> Protection from Pollutants (Stormwater Management Manual for Western Washington <br /> -C.3) <br /> All wetlands (Categories I, II, Ill and IV)must receive the following protection from <br /> pollutants: <br /> 255 S.King Street,Suite 800,Seattle,WA 98104 I 206.426.2600 I JACOBSONENGINEERS.COM <br />
