Sec 117.384-410 <br />Revised July 29, 2014 to include 2013 Construction Stormwater Permit, 2013 MS4 Permit <br />requirements and 2012 LRRWMO Third Generation Plan [deletion;,, additions] <br />Sec. 117 3ei. Vegetated buffer protection for rivers, streams and wetlands. <br />{a) The city has e+f\Niched wetland buffer regulations (see subdivision VI of division /I of <br />this article) specifying minimum cotbacks from wetlands in the city. Setbacks are also <br />o ,tablished for the rivers that border the city and the lakes internal to the city. <br />{1) Detailed buffer design is usually site specific. Therefore the city engineer can require <br />a larger buffo than the minimum. <br />{2) For newly constructed buffer sites the design criteria should follow common principles <br />and the example of nearby natural areas. The site should be examined for existing <br />of ones and mimic the slope structure and vegetative cc much as possible. <br />Quffor dosign and protection during construction should slow water runoff, trap <br />sediment, enhance watt' infiltra+ic\n, trap fors, posticidos, pathogens, heavy <br />trap !� . <br />During construction temporary sedimentation bocinc ore required for disturbed areas <br />over one acre. <br />(2) <br />(`) <br />Quffe, rinnt colectivn ahall give preference to native p cinc with deep root systems <br />over cultivated species with shallow root systems. <br />{6) The buffer wkthc cthall conform to subdivision VI of division /I t'f this artiGla <br />{7) The state department cf natural rosources roquiros pormits when vegetation is <br />introduced downgrade of a waters "ordinary high watts mark."
