Wallingford is a neighborhood in north central Seattle, lying on a hill above the north shore of Lake Union about four miles from the downtown core. The neighborhood developed quickly during the early 20th century after the establishment of the University of Washington to the east. With trolley tracks laid through the neighborhood as early as 1907, Wallingford is a classic streetcar suburb, typified by its many 1920s era box houses and bungalows. Commercial development is primarily concentrated along North 45th Street where a number of iconic structures stand including the neon "WALLINGFORD" sign, the Wallingford Center, and the original Dick's Drive-In. With its central location, numerous public amenities, including the world-renowned Gas Works Park, and views of both the Olympic and Cascade mountains, Wallingford has long been home to many middle and upper-class families. While Wallingford is mostly residential in nature, the neighborhood's southern edge, along Lake Union, has historically been an industrial and commercial business strip. In recent years, numerous office buildings have been developed as an extension of the burgeoning business center in neighboring Fremont. In 2014 Brooks Sports moved its headquarters from Bothell to a new six-story office building at the southwestern edge of Wallingford. Boundaries Like all Seattle neighborhoods, there are no official boundaries for Wallingford. Geographically speaking, the neighborhood is primarily defined by the sloping ridge that runs north from the edge of Lake Union to 45th Street, with the ridge line approximately following Wallingford Avenue. Generally the boundaries are considered as Aurora Avenue to the west, Interstate 5 to the east, Lake Union to the south, and 50th Street to the north; however the western and northern boundaries are often debated. The Seattle City Clerk defines the area south of 45th Street and west of Stone Way as part of Fremont. A number of businesses in this southwestern section, particularly those south of 40th street, use the Fremont moniker in their names, such as the Fremont Collective at Stone Way and 35th Street and the Fremont Brewing Company at 34th Street and Woodland Park Avenue. The 1998 Neighborhood Plan defined the northern edge of the neighborhood as 60th Street, however the area north of 50th street is sometimes associated with Green Lake and sometimes considered part of the distinct neighborhood of Tangletown/Meridian, a northern part of Wallingford. The cultural center of the neighborhood is frequently considered the intersection of 45th street and Wallingford
