near. There are several houses on the east side of the Jordan River on present day California Avenue that were built prior to 1930. Between 1930 and 1960 Based on aerial photography, a significant amount of residential development occurred in the Glendale neighborhood from 1937 to 1958, which is coincident with the post-World War II expansion. The first major subdivisions built in Glendale were built in the 1940s and early 1950s. The early subdivisions were part of the Glendale Gardens housing project, built to accommodate a large influx of families moving to Utah for the war effort, associated with the relocation of the Ninth Service Command to Fort Douglas, Utah. The area south of California Avenue, east of 1200 West, and west of the Jordan River, was developed from 1947 to 1952. The area north of California Avenue and south of Glendale Drive was also developed at this time. The main development in the western, industrial part of Glendale was the Utah Ordnance Plant. This area was operated by the Remington Corporation. In 1941, several buildings were constructed within the Utah Ordnance Plant area for the purpose of producing World War II ammunition. The Utah Ordnance Plant was in operation from 1942 to 1943 and was in standby from 1944 to 1946. The area was decommissioned and sold after 1946. Post 1960 The Glendale area continued to develop to its present status. Most of the present apartment complexes were built during this time . ISalt Lake County worked with the Utah division of Parks to establish the Jordan River Parkway during this time. Level of Development as of 2012 Of the 7601 acres of zoned land within Glendale's boundaries, 7.5% (571 acres) is commercial, 56.7% (4309 acres) is manufacturing/industrial, 28.8% (2189 acres) is special purpose (open space, public land, and agriculture), and 7% (532 acres) is residential. As of 2010, Glendale has a population of 9962 people living in 2751 houses. Post-2012 Development The preliminary West Salt Lake City master plan outlines many improvements for the west side of Salt Lake City, including improvements to the area's entrances, upholding property maintenance standards, improving bicycle access, and improving the appearance of roads in the neighborhoods. Bordering the north extent of the Glendale neighborhood, the 9 Line Trail is a new trail network connecting West Salt Lake City to the rest of the city. Neighborhood Glendale is a neighborhood full of diversity.
