Happy hyperbolic holidays!

The entryway to the Sacramento Zoo, designed by Rickey & Brooks (1961).

The largest building originally served as a concession stand to all of William Land Park.

The City of Sacramento recently hired consultants from Mead & Hunt to conduct a Historic Cultural / Landscape Survey of William Land Park. Per Mead & Hunt's report, these hyperbolic paraboloid structures "meet the National Register, California Register, and Sacramento Register evaluation criteria as individual properties independent from their association with William Land Park."

Further, Mead & Hunt concluded the Zoo entry structures were eligible "in the area of Architecture – Designed by the local architectural firm of Rickey and Brooks, this series of three interconnected buildings are an important, rare, and intact example of Mid-Century Modernism in Sacramento."

On December 7, 2011, SacMod attended the City of Sacramento Preservation Commission Meeting and spoke in favor of Mead & Hunt's report: "We want to thank everyone involved in the Historic Cultural Landscape survey of William Land Park and support Mead & Hunt's findings, especially those regarding Fairytale Town and the entryway concession buildings at the Sacramento Zoo. SacMod highlighted both of these historic assets as 'points-of-interest' during the first Sacramento Mid-Century Modern Home Tour last year. These have been a part of the park for 50 years and are historic landmarks.

The Zoo entrance and Fairytale Town are part of Sacramento's collective memory and provide an irreplaceable and distinct sense of place. In particular, the structures at the Zoo entrance are a rare kind of mid-20th century construction – hyperbolic paraboloids – also known as hypars. I have brought an historic postcard image for you to see them as they originally were. There are few remaining examples of hypars left in Sacramento. The Zoo entrance structures are the most easily recognized examples in town.

SacMod supports Mead & Hunt's recommendations and wishes to see our historic assets preserved. We look forward to working with the City and Zoo in this regard."
