THE LAST BEST PLACE FOR A 55+ RETIREMENT COMMUNITY Nestled between the Sapphire & Bitterroot mountains, Riverside Crossing offers the advantages of ownership and the convenience of cooperative living. This 55+ community designed by Ross Chapin is based on the Pocket Neighborhood concept. Membership in the cooperative includes cottage maintenance, inside and out, lawn and landscape care, and snowplowing and shoveling. With one monthly service fee, cooperative staff take care of most of your monthly billings and maintenance. Knowing your cottage is cared for while you are away gives you peace of mind to travel without worry. Members of the cooperative own and, through the Board of Directors, control the property.
