Bothell, WA 98011 "" ""�" "°�•"' [VENETT. W�lNIHGTON •�301 Dear poug: This letter is intended to explain why we determined that a 16" water main was needed on Seaview Way extended from 20th Ave. W. in Everett. As you know, the 16" main Installed as a part of your project is the sole means of supplying the Fluke Co. property as well as, in the short run, the Washington Services and Kenilworth Hills property. Long-range plans for the area cali for bringing another supply into S. W. Everett from the East but the Fluke and Kenilworth projects, at least, will be built several years before this alternate supply can be constructed. For the Fluke site alone, the 16" main is necessary to obtain the requirad fire flow at the site under present conditions (on the order of 3U00 gpm) and, it appears that it is required to obtain adequate flows even after a second supply is brought into the area due to expected growth on the Fluke properties and others in the immediate vicinity. This " area on the high ground has fairly low static pressures so ailowabie head losses under fire demand conditions are small and it is likely that the Fire Marshal's requirements at the Fl�ke site would drop pressures below allowable minimums in the local area even with the existing 16" n�ain. We don't see this as a major problem at this point since most of the local area is Fluke property but it does clearly indicate a need for the 16" main to adequately _•erve the Fluke site. The City has indicated previously iliat it would not participate in the cost of the 16" main on 20th Ave. W. for the abave reasons. We have, however, indicated that it Is likely that we will require one of the North-South mains in the Kenilworth Hills plat to be oversized to accommodate demand in the area North of the plat. If this is the case, we would participate in the cost of the oversized main in the plat, and as far South as the point at which it wou!d be connected to another large main. I hope this has answered any questions you have and wish to apologize for any mi� ..�id�rstanding which may have developed due to my not writing this letter earlier. Sincerely, HUGH WARREN, P.E.
