The POS-SMP has indicated that all grass infield areas surroundingrunways and taxiways would be managed as water quality treatment BMPs (filter strips),and therefore will be managed per the BMP maintenance plan to be developed once improvements are complete. However, because these areas exceed the 1 acre thresholdof managed landscape they appear to also be subject to treatment requirements or a landscape management plan requirements. Since the treatment BMP that would be required for the landscaped areas would be more of the same grass filter strips, I am unsure how to deal with the issue. Attached is the proposed SMP section to address the issue of the managed landscape. My initial comments are in underline format. Please advise. ---Kelly. Kelly R. Whiting, PE King County Department…
