l <br />• The StormFilter must treat at least the 6-month, ,'_4-hour storm. <br />. The StormFilter shall be designed using a maximum Flow rate of 7.5 gpm p�r cartridge. <br />Flows exceeding the design Flow shall be bypassed aro�nd the system, but should <br />generally pass through the pretreatment wetvault/tank. <br />. The StormFiiter media shall target dissolved pollutants and nutrients as well as total <br />suspended solids. As more effective media become available in the future, the <br />StormFilte°r shall be upgraded, during routine cartridge replacement, to utilize these <br />improved ���zdia. <br />. The StormFilter shail be designed with a minimum of 2.3 feet of head differential <br />between the inverts of the inlel and outiet of the filter. Downstream hydraulic <br />calculations will be performed to demonstrate that downstream conditions will not reduce <br />the hydraulic potential across the filter due to backwater effects. <br />. Routine maintenance of the StormFilter is required. A detailed operation and <br />maintenance plan for tiie system must be prepared for approval by the City. A cerlificate <br />of system maintenance must be submitted to the City annually. <br />. Maintenance and operetion of the StormFilter on this site shall be adapted, in the future, <br />to reFlect the current knowiedge regarding this emerging technology. <br />. All other applicable, and non-conflicting, criteria in the current edition of SMI's Product <br />Design Manual shall be followed in the design, construction, and maintenance of the SMI <br />StormFilter on this site. <br />15. Portions of the existing mall complex discharge to the existing easterly and westerly <br />detention ponds on the site. In these ponds, the stormwater receives a limited amount of <br />stormwater treatment in addition to detention. Stormwater runoff from existing areas of the <br />mall complex which wiil not be "redeveloped" as a part of this project must continue to <br />receive at least an equivalent amount of stormwater treatment as currently occurs. <br />16. Parking must be per City Zoning Code and City Design and Construction Standards for <br />Development. <br />17. This project must comply with the current State Building Code (IBC) and the City of Everett <br />Sprinkler Ordinance. City of Everett construction permits are required. <br />18. Special charges for connection to the sewer and water systems in accordance with Ordinance <br />1998-94 and subsequent revision are applicable. These charges are based on orojected <br />water usage and can be substantial. Applicant is encouraged to obtain a copy of the <br />Ordinance and determine estimated charges prior to buiidirg permit application. The actual <br />charges shall be computed by the Public Works Department per the ordinance in effect at the <br />time and according to the information on the approved plans at the time of building permit <br />issuance. <br />19. Lack of comment on the plans submitted with the application does not constitute approval of <br />these plans. <br />20. City streets and alleys are to be kept clear of dirt and debris at all times during cor�struction. <br />Dust suppression and street cieaning must qccur as directed by the Public Works Inspector. <br />�\ <br />� <br />
