"On October 25, 1980, the City of National City and the Community Development Commission of the City of National City formally dedicated the Frank A. Kimball House which is a part of Heritage Square. Heritage Square is located between 9th Street and Plaza Blvd. along "A" Avenue in National City. On the easterly side of "A" Avenue is the Kimball House, the Elizur-Steele-Crandall-Ennis House, and the Proctor House. On the westerly side of "A" Avenue is Brick Row, a ten unit row house which was built by the Kimball Brothers and is on the National REgister of Historic Places. The street in front of these houses was reconstructed to visually coordinate with these historic buildings." (quote from Kile Morgan, Heritage Square, published 1980)

The official welcome sign of National City designed by Ed Pieterson used the image of the Elizur Steele house that was built in 1879 at 904 East 8th Street and moved to Heritage Square in 1977.

The Rice-Proctor house was built in 1887 by Julius A. Rice at 1311 Roosevelt Avenue and moved to Heritage Square in 1978.
