21.13.090 MDD3 | Redmond Zoning Code

21.13.090 MDD3.

This section has been amended by Ordinance 3083, which is pending codification.

This section was recently amended by Ordinance 3074, codified in April 2022.

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.
