The walking paver areas are considered impervious. Permeable pavers are a means of mitigation of the walkway area. (Please contact Stormwater Engineer Jerry Shuster for further information). Rough calculations from the scaled plan indicate that the total proposed impervious area is closer to 5600 sf. Please recalculate and revise plans. 8.Please provide a stormwater site classification worksheet for this project. The worksheet can be found in the Handout E72 (http://www.edmondswa.gov/images/COE/Services/Permits_and_Development/Forms_and_Handouts/E72- SWM_Erosion_Control-03.05.12.pdf). Based on the amount of new impervious surface proposed, it appears it will classify as a Category 2 Small Site Project. Please verify. 9.Please provide a stormwater report including the requirements of Chapter 5 of the Edmonds Stormwater CodeSupplement, (http://www.edmondswa.gov/images/COE/Government/Departments/Public_Works/Sto rmwater_Utility/pdf/EdmondsStormwaterSupplementFinal20100428.pdf). 10.Please provide an engineer designed stormwater system.
