The only other redline I have on the plans from the other reviewers was to note on sheet L4.0, Utility Notes 19, 21 and 22 that the service line,tap and water meter are to be installed by City of Everett Crews under separate Utility Permit.

There are a couple follow up questions that need further discussion (rubber surface material, treatment requirements,flow from offsite..), but I wanted to get these comments to Tom. Plans Review: Plan sheet L4.0: Grading Drainage and Utility plan The Ecology manual guidelines for site suitability criteria state that an infiltration facility should be a minimum of 100 feet upslope from any building structure foundation (SCC1 V5, Ch5.6). The infiltration facility appears to be only 80 ft from the YMCA building and 40 feet from the potential future YMCA addition. The Geotech Report recommended foundation drains and blanket drains full height for the wall of the structure. There was no recommendation in the report on setbacks, consult with AESI on building setback requirement (if any) for infiltration on this specific project. Parks to follow up with AESI The infiltration facility appears to be approximately 465 feet from a medium level landslide/erosion area and 550 feet from a high level erosion hazard area, this meets City setback requirements. The geotechnical engineer also conducted a slope stability analysis for the YMCA project, confirm with AESI if the analysis included infiltration from the park. Parks to follow up with AESI The 9,971 sf rubberized surfacing is considered by Dept. of Ecology to be a pollution generating surface. Treatment will be required for flows from the rubber surface to the infiltration facility(provide treatment unit immediately upstream of infiltration facility). Had meeting with Erik Emerson on this. Concluded that surface meets pervious pavement criteria. Therefore adding 6" runoff treatment gravel layer per Std. Dwg. 430.
