with prior approval by the City of Everett.These are options to consider after the above <br /> listed BMPs are evaluated. <br /> 2. Determine which options you must use for managing stormwater from hard surfaces(driveways, <br /> paved pathways, etc.) by considering the following for each type of hard surface proposed: <br /> • BMP 12.60 Concentrated Flow Dispersion <br /> • BMP 12.70 Sheet Flow Dispersion <br /> Note: Propose an alternative stormwater management plan if none of the above BMPs can feasibly be <br /> installed. (Examples:Shallow vegetated swale, perforated pipe stub-out, etc.) <br /> Provide your Evaluation below and Show where these will take place on a site map: <br /> We will be planning to maintain the existing stormwater management systems on the site.The existing <br /> roof will not be modified (aside from existing HVAC units being replaced in the same locations)and as <br /> such will maintain the interior drainage lines within the building that currently connects to the <br /> combined sewer. <br /> We are proposing a net loss of imeprvious surfaces over both lots and increasing the amount of <br /> landscaping scattered throughout the main parking lot and the accessory parking lot.Therefore we are <br /> not proposing any changes or additions to the existing stormwater drainage system.See attached Site <br /> Drainage Plan for reference. <br /> Page 5 of 8 <br /> CITY OF EVERETT I 3200 Cedar Street I Everett, WA 98201 I 425-257-8810 I everettwa:gov— <br /> ""' <br />
