SEC. 5. STATEMENT OF SIGNIFICANCE.
Identified through the Mission Dolores Neighborhood Context Statement & Survey, the Alert Alley Early Residential District is a one-block long stretch of properties, centered on Alert
Alley and Landers Street, significant as a representative collection of Italianate, Classical Revival, and Queen Anne residential buildings associated with the themes of “Early Neighborhood
Development (1864-1906)” and “1906 Earthquake and Reconstruction (1906-1915).” The period of significance is 1890 to 1910. The District is comprised of 21 properties, eighteen of
which include contributing resources, located in the Mission Dolores neighborhood. There are three non-contributing properties.
The Alert Alley Early Residential District is significant as a representative collection of residential buildings that physically illustrate the neighborhood’s pre- and post-1906 Earthquake
and Fires development transition. Because it was spared from the 1906 fires that decimated many other nearby neighborhoods, the district provides a unique combination of early, small
scale single-family homes along with post-1906 reconstruction era larger scale multi-family flats and apartments. The Alert Alley Early Residential District is a collection of buildings that
represents the early small-scale residential and agricultural development patterns of the Mission Dolores neighborhood as well as larger residential flats and apartments indicative of the
post-1906 reconstruction period. The district is also notable as it contains several buildings, including 260-264 and 266-268 Dolores Street, associated with the Dolores Street Fire Line,
which served as a firebreak preserving properties west of Dolores from destruction in the devastating post-earthquake fires.
The Alert Alley Early Residential District also is architecturally significant as a distinctive grouping of Victorian-era residential dwellings in Italianate, Stick-Eastlake, and Queen Anne
styles. Along the narrow alleys, the pioneer origins of the buildings are indicated via setbacks, small building footprints, and low-slung massing, which stand out amongst the many larger
rowhouses and flats that comprise much of the rest of the urbanized neighborhood. In the post-earthquake period, the Mission Dolores neighborhood transitioned from a semi-suburban,
single-family dwelling area at the periphery of the city, to a dense neighborhood fully integrated into the larger urban context, characterized by an increase in multi-family development,
particularly with the construction of apartment buildings and flats, including “Romeo Flats,” in Classical Revival and Queen Anne architectural styles.
The period of significance for the District is 1890 to 1910, inclusive of the period of construction of all contributing buildings within the District. Additional historic information, and
descriptions of individual buildings, may be found in the Alert Alley Early Residential District Designation Report, which is hereby incorporated herein as though fully set forth.
