Because the 2014 SWMMWW doesn't require enhanced <br /> treatment, I am more than happy to be found wrong!

Please expand Section 7 to indicate compliance with the updated language for MR9. <br /> WWHM2012 results: <br /> v. And an FYI—for future reference the next time you submit a project for City of <br /> Everett approval,please update the version of the WWHM2012 you are using.
