I discussed your <br />project with our Storm Engineer to confirm that my request for impervious surface calculations was <br />appropriate since I know that a large part of the paving was replacement of existing impervious surfaces. <br />He agreed that the calculations are necessary. As the total impervious is well over 2000sf (the pavers <br />alone are close to 2000sf), it is important that we know where the undetained water is going so we can be <br />sure that there are no problems in the future. I recall that when I spoke to the owner once on site and <br />another time in our office I did explain that these calculations as well as drainage information would be <br />required on his site plan. The owner had also mentioned that a drainage system had been placed under <br />the pavers in the backyard patio area. This also should be shown on the site plan; a detail of the system <br />and lines showing where the drainage is being diverted. We had discussed adding a drywell in the front <br />yard as well. If that has been added, please show on the site plan and show what being drained into it. <br />Please also indicate on the site plan the location of any catch basins in front of the property. <br />If you have any further questions, please let me know. <br />Thank you, <br /> <br />JoAnne Zulauf <br /> <br /> <br /> <br />-----Original Message----- <br />From: Zulauf, JoAnne <br />Sent: Thursday, February 12, 2009 9:39 AM <br />To: '' <br />Subject: Eng Comments Zubair <br /> <br />Please see attached comments; <br /> <br /> <br />JoAnne Zulauf <br />Engineering Technician <br />City of Edmonds <br />(425) 771-0220 x1324 <br /> <br /> <br /> <br /> <br />
