MF.MORANDUM <br /> •C0: Kirk Brooks <br /> FROM: Jane Zimmerman <br /> DATE: July 31� 1992 <br /> SUBJECT: Boeing 40-41 Site Work and Utilities, <br /> Plan Review <br /> I would like some more information relating to the fatique <br /> test slab and the operatinq procedures for the oil/water <br /> separator provided in conjunction with it. IPT may need to <br /> be involved as the slab�s drainage can be routed to the <br /> sanitar.y sewer via the oil/water separator. Once we know <br /> sore about the test slab and expected flows and contaminants <br /> from it, we will probably need to review oil/water aeparator <br /> calculations. <br /> The plans refer to the "Boeing Comprehensive Drainage Plan". <br /> This document sounds interestinq and might help us interprat <br /> these and future drainage plane if it exists. Do you think <br /> that we could get a copy? <br /> The hydrology of the wetlands to the west of tha eite must <br /> not be adversely affected by the development on the eite. <br /> If this site is a significant source of water for the <br /> wetlands, some provision will need to be made to continue to <br /> deliver a similar rate and quantity of raof run�ff or <br /> treated pavement runoff to the wetlands after development of <br /> the site. The Planning department will need to review and <br /> approve a hydrologic analysis of the wetlands that studies <br /> these issues. <br /> � <br /> I� I <br /> 1 <br />
