A. Purpose. The purpose of the Marymoor Design District 3 (MDD3) is to implement policy calling for a walkable subarea that develops in a way that supports Bear Creek, Lake Sammamish, Redmond’s drinking water aquifer, and other natural features. Shallow groundwater and lack of a stormwater outfall will require creative designs on the part of developers. To facilitate that, regulations are intended to allow developers to work within the natural constraints of the land. MDD3 will feature opportunities for living and community gathering, enhanced by proximity to Marymoor Park.

The following table is specific to this zone and provides references for each of the major topics that are regulated throughout the code. The individual topics provide function as connection or linkage to the chapters and sections of the Redmond Zoning Code that apply to development within this zone.
