That's what being out of the office for five days does to me... <br /> Anyhow, I think they need to do a rain garden in the area between the patio and the fence to mitigate for the additional <br /> pavement, especially since the pavement is likely to be parked upon. Therefore, I would like for them to excavate a <br /> shallow bioretention cell/swale in the space between the pavement and the fence, with the low side being the fence <br /> side. The bioretention area must provide at least 8" of ponding depth, with the soils heavily amended - as Jesse <br /> suggests below- and planted with rain garden zone 1 and 2 vegetation. Vegetation can be chosen from the WSU Rain <br /> Garden Handbook for Western Washington, which is available for download at the following link: <br /> https://fortress.wa.gov/ecy/publications/SummaryPages/1310027.html <br /> Thank you, <br /> Jane <br /> -----Original Message----- <br /> From: Kirk Brooks <br /> Sent: Thursday, November 19, 2015 7:49 AM <br /> To:Jane Zimmerman <br /> Subject: FW: 29 and 31 112th st Drainaige <br /> Jane z, <br /> Have you had a chance to consider what Jesse is talking about? <br /> Thanks, Kirk <br /> -----Original Message----- <br /> From:Jesse Jarrell [mailto:jessej@wesi.co] <br /> Sent: Tuesday, November 10, 2015 2:00 PM <br /> To:Jane Zimmerman <br /> Cc: Kirk Brooks; 'Lance Harvey' <br /> Subject: RE: 29 and 31 112th st Drainaige <br /> Jane, I realized earlier that we actually designed this plat back in 1997-2000. 1 was able to pull our job file out of archives <br /> and look at the site design. Per review of the old report and drawings, only lots 1-7 (and the private road) of the plat <br /> were designed and accounted for in the detention system sizing under the private road. Lots 8-11 (project located on lot <br /> 11) were only specified with draining the roof drains to a infiltration/dispersion trench along the 25' stream setback with <br /> no sizing or impervious areas notated for any lot. <br /> 1 <br />
