The Lake Minterwood Beach Club (LMBC) is a non-profit corporation that includes as members all of the property owners of the Lake Minterwood Plat as recorded in the Pierce County records. Its purpose is to maintain the lake and property it owns exclusively for the pleasure, recreation and other similar nonprofit purposes of the members.
