RICHLANDFAIRBANKS_ ANCHORAGEGEOTECNNICAL AND ENVIRONMENTAL CONSULTANTS DENVER SAINT LOUIS BOSTON MEMORANDUM DELIBERATIVE- DO NOT DISCLOSE TO: Ann Kenny, Washington State Department of Ecology FROM: Katie Walter DATE: August 7, 2001 RE: DRAb'q"401 CONDITIONS FOR THE PORT OF SEATTLE NRMP AUBURN MITIGATION SITE REVISIONS 1. The revised grading plan (June 28, 2001) shows a culvert in the northwest corner of the site in the proposed new drainage swale. The culvert will pass flows under the site access path. The drawing shows this culvert approximately 60 feet long, passing under a path that is only approximately 15 feet wide. This culvert should be no longer than is necessary to pass the water under this pathway. 2. The revised grading plan (June 28, 2001) shows a culvert in the south central portion of the mitigation site. This culvert appears to be mislocated. It appears that the culvert should be shown in the wetland directly east of the shown location, where the wetland passes under the proposed maintenance path. This culvert should be no longer than is necessary to pass the water under this pathway. 3. Two additional culverts need to be shown along the new drainage swale where the water outlets the southwestern basin, under the maintenance pathway. 4. Culverts should be placed during construction under the paths/roads in all areas where there is a potential for impounding water. A note should be added on the construction documents. - AR 033698 400 NORTH 34TH STREET ' SUITE 100 P.O. BOX 3O0303…
