' Potential Re uirements and Solutions <br /> 1ZequiremenL orSolution Yes/No <br /> 1 The release of any non-native fish, amphibian, or reptile should be strictly <br /> prohibited in any waterbody. <br /> <br /> ' 2 The use or release of any non-native plant or any non-native animal should be <br /> strictly prohibited near any waterbody in the ~n-~neSalmon Guidelines <br /> Area. For landscaping and revegetation plans, see Section 4.2. <br /> 3 If an "aesthetic water feature" such as a pond or fountain is proposed, implement <br /> strategies to ensure that any introduced species will be quickly removed from the <br /> water feature.

Pollutants such as oil, toxic chemicals, radioactivity, carcinogens, <br /> mutagens, teratogens, or organic nutrient-laden water (including sewage water) can kill salmon and <br /> man other a ua <br /> tic or <br /> Y anisms. Pol <br /> q lutants that ent <br /> g er the stormwa <br /> ter system anywhere m the City will <br /> flow into the Willamette or McKenzie Rivers. Even in areas with low density land uses, turbidity, silt, <br /> and nutrient concentrations can be high enough to affect salmon. <br /> Ke Question <br /> # Key Question, Ycs/1~`o <br /> 1 For any prof ect in the Salmon Guidelines Area, proceed to the <br /> Potential Requirements and Solutions table below. <br /> Potential Re uirements and Solutions <br /> # Requirement or Solution Wes/loo <br /> 1 For sediment and some other pollutants: Utilize Stormwater best management <br /> practices (e.g., such as bioswales, wide riparian buffers, or mechanical facilities) <br /> to treat water prior to draining into asalmon-bearing stream. <br /> 2 For sediment and some other pollutants: Minimize the amount of impervious <br /> surface in the riparian area. Use alternative methods such as pervious concrete, <br /> green roofs, and bioswales to minimize Stormwater run-off. <br /> i <br /> Guidelines for Salmon 4-19-04 Page 18 <br /> <br />
