A. Purpose. The River Bend (RVBD) zone is one of four distinct mixed-use residential/office districts in the Downtown Neighborhood: Sammamish Trail (SMT), Town Square (TSQ), Anderson Park (AP), and River Bend (RVBD). All four zones are intended to provide for significant residential growth, as well as opportunities for growth in professional, business, health, and personal services. These zones provide for a range of employment uses, such as financial and professional services, public administrative offices, health services, advanced technology industries, universities and technical colleges, and other activities normally conducted in multistory office structures. These zones are intended as areas for the densest employment and residential uses in the Downtown, but also provide for supporting retail, service, and entertainment uses located within walking distance of each other. Some of the quieter streets in these zones allow residential uses on the ground floor, whereas the primary streets are intended for active, pedestrian-friendly and activating commercial uses. The River Bend zone enhances this area as an entrance to downtown by requiring streetscape improvements, by using design standards to encourage the creation of mixed residential/office villages and buildings, and by linking the zone with the Downtown core and Sammamish River. The River Bend zone also preserves the “green” gateway on Leary Way at the south end of Downtown by providing for the acquisition of land and the application of design standards and forest management. .
