PROPERTY LINES AND RIGHT -OF-WAY SHOWN ARE SOURCED FROM KING COUNTY ASSESSORS GIS DATABASE, AND ARE NOT INTENDED TO IMPLY A BOUNDARY SURVEY. SOME RECORD OF SURVEY WORK WAS DONE IN ORDER TO BETTER PLACE THE ASSESSOR MAP LINES. THE RECORDS USED BEING: KC SP #385086, KC SP #479069, KC ROAD PAPERS FOR STOSSEL CREEK ROAD SURVEY 1/34-26-7-2 EST. 4/6/36 CC VOL 34 PG 471, AND SURVEY OF SHORT PLAT 385086 ROS 8703189008 BOOK 054
