|This is Additional Documentation for the Avenues Historic District. The Avenues Historic District, located northeast of Salt Lake City's historic center, was originally listed on the National Register of Historic Places in 1980 (NRIS #8003915). The period of significance for the original nomination spanned the 1850s to the 1930s. The objectives of this amended nomination include expanding the historic period to include mid-twentieth century resources, providing contextual periods for understanding the neighborhood's development, and updating the tally of contributing resources. The period of significance for the Avenues Historic District has been refined to begin at 1857, the year the neighborhood plat was formally filed, to 1965, the year the last single-family dwelling was built prior to a period of multi-family residential conversions and apartment block construction.
