It evaluates the top priorites for households concentrated development surrounded by healthy future growth and recommends several urban single family neighborhoods.” The neighborhood design improvements that will be great amenites This UDF will be used to express the preferred vision plan encompasses all facets of Northgate’s future, promotng livability, a beter environment and and design priorites for the future development foreseeing: a well-functoning community.

Findings
This Urban Design Framework (UDF) guides future actons that will help realize the vision identfed in Northgate’s 1993 neighborhood plan, calling for dramatc growth and transformaton of the commercial core into a livable, walkable, dense urban center.
The UDF recommends both general and specifc actons that the City will seek to implement, to achieve goals of the City’s Comprehensive Plan, the neighborhood plan, and related objectves to improve Northgate as a livable and well-served Urban Center.
These include actons that support: future transit- oriented development (TOD) with high-quality public places, next to the Link transit staton; enhanced transit services and operatons; and investments to improve pedestrian and bicycling mobility and safety.
These can transform the Urban Center to a beter living environment, enhance transit accessibility, and overcome difcultes posed by the presence of Interstate 5 as a barrier within the neighborhood, and the large “superblock” road confguratons.

How Northgate Relates to Seattle and the Region NORTHWEST HOSPITAL Located six miles north of downtown, Northgate is one of six Urban Centers designated in Seatle’s Comprehensive Plan, and one of 27 regional growth centers designated in Puget Sound Regional Council’s (PSRC) Vision 2040 regional growth management plan. The Urban Center includes 410 acres on both sides of Interstate 5. The Urban Center is at the conjuncton of several surrounding residental neighborhoods, including Licton Springs, Haller Lake, Pinehurst, and Maple NE Northgate Way
Leaf, with others such as Victory Heights, Lake City NE Way Roosevelt and Green Lake nearby.
Northgate is one of the City’s largest retail, medical and ofce centers outside of downtown and home MALL to one of the City’s largest hospital complexes Meridian Ave N Meridian Ave NE 5th Ave outside of central Seatle. This refects its locaton NE Ave 1st near Interstate 5 and its history as a traditonal automobile-oriented commercial shopping district that also provides a variety of medical NE 103rd Street and educatonal services to all of North Seatle. The adjacent North Seatle Community College is a key asset with a mission to provide 21st Century educaton, training and services to elevate residents’ compettveness in the job market and aid Seatle’s economic vitality.
