• TNE BOEING COM7ANY <br /> COORDINATION SH�ET <br /> From: Leonard Astemborski No.: 156 <br /> M/S OF-76 Job No.: <br /> 266-3563 Date: April 7, 1992 <br /> FAX 342-8167 <br /> To: Kurt Eichmeier OF-76 <br /> CC: Kirk Brooks Everett Public Works <br /> Carroll Tolleison Everett Public Works <br /> SubJect: Biofiltration Swale 40-55 Building <br /> This coordination sheet fs it confirm the verbal agreement between Kirk Brooks, <br /> Carroll Tollefson and Len Astemborski. It was mutualiy agreed that since the City <br /> Standards regarding the frequency oi plantings in biofiltration swales calls for <br /> vegetation plantings to be 1 every linear feet of swale. The biofiltration swale <br /> illustrated does not have a scale or dimension to the bottom measurement o�the <br /> swale. The City says the intent of the standard was that the swale illustrated to be <br /> 1 foot wide. Most commonly this is true throughout the City by other contractors. <br /> Since Boeing does work on a grand scale and that the swales needed ere larger <br /> than the typical 1 foot wide swale and the interpretation of the standard becomes <br /> foggy. The City is willing to use the irequency of plantings to be 1 plant every two <br /> feet in both directions rather than 1 plant per square foot of bottom swale. <br /> The concept is illustrated below: <br /> X X X X X <br /> X X X X X <br /> X X X X X <br /> X X X X X <br />
