Vern Cummings, Park Shadelands Business Park


Daly City, CA was named after businessman and landowner John Daly, and located due south of San Francisco. John Daly prospered after the earthquake of 1906 when residents were desperate for food and dairy products.

The heavy fog that is common in the area discouraged early settlers, but the fertile soil was good for farmers. The arrival of the railroad made it easier for farmers to get their crops to market and brought additional settlers to the area.

Daly City was one of the few cities to allow gambling in the bay area, and found it helped attract visitors and money from both near and far.

On March 18, 1911 a special election was held where the incorporation of the city passed by a narrow two vote margin.

The city remained fairly small until the 1940’s, when developer Henry Doelger established Westlake, answering the need for housing and businesses upon the ending of WWII. Westlake Shopping Mall is still one of the largest in the entire bay area. The fact that there is adequate parking and lower sales tax attracts buyers from the San Francisco bay area.
