• DD6 - A shrub or tree must be planted in the Filterra Unit. The plant shall be selected from the manufacturer's <br />a approved list of plants for the Pacific Northwest and shall be a size and type appropriate to the Filterra location. <br />The plant shall meet clear zone and visibility requirements as appropriate. <br />• DD6 —The rain garden shown is not required to meet MR 6 or 7 unless the building roof is made from a pollution <br />generating material. Since no calculations were provided the rain garden was assumed to be a voluntary <br />measure. As such it was not reviewed to determine compliance with stormwater standards and will not be <br />tracked as a water quality facility by the City. Consider expanding the gravel backfill under more of the rain <br />garden to promote infiltration. <br />Erik Emerson PE <br />City of Everett, Public Works <br />Senior Surface Water Engineer <br />3200 Cedar Street <br />Everett, WA 98201 <br />Direct: 425-257-8995, Fax (425) 257-8882 <br />eemerson@everettwa.gov <br />
