This will affect proposed deckcover impervious surface calculations. 4)Please label and show all impervious surfaces on the plans (walkways, patios, gravel,etc.) and sq.ft.as well as provide the date of construction. Please revise the impervious surface calculations accordingly. 5)Ingeneral, newimpervious surfaces as of 10/16/1995 (date of annexation),exceeding2000sqft, will require a storm water management system.Per the attached plan it appears approximately 2400 sf of impervious area was approved to drain to the existing plat storm system adjacent to your lot. Additional impervious areas added to the site will need to provide alternate mitigation. Alternatively if you can provide documentation that the existing plat system can handle the additional flows then that may be a viable option. Please show the storm water mitigation system if required. Please see attached E72 for further explanation. 6)For info: Possible mitigation systems -dry wells, rain gardens, detention systems or infiltration systems. Please resubmit 3 copies ofthe revised plans/documents to a Development Services Coordinator.Please contact me at 425-771-0220 if you have specific questions regarding these plan corrections.
