The following is a partial listing of historical hillside properties for which Parmelee/Geology has provided engineering geologic consulting services.  The listed properties represent work done by noteable architects or construction which defines a certain architectural style. The level of our geologic involvement in these projects varies from evaluations of existing site and structure performance to providing detailed recommendations for stabilization, renovation or new construction.


      Taggart House, 5423 Black Oak Drive, Los Feliz - 1922 Lloyd Wright  Parmelee Geology was initially hired to perform an overall site evaluation. Our continued work on the project has included the collaborated preparation of a comprehensive geologic and soils engineering report provided to assist in the complete restoration of original structure and stabilization of secondary site structures. Work is being performed under the architectural direction of renowned architect, Eric Lloyd Wright.  General contracting work was performed by Tom Montgomery.


                  Warwick Evans Residence, 12036 Benmore Terrace, Brentwood - 1936 Lloyd Wright - Parmelee Geology was hired to perform an evaluation of the site geologic conditions prior to purchase.

California Street, Pasadena.  Heineman and Heineman residence.  Work to be performed includes stabilization and replacement of the early 1900's unreinforced stone and mortar foundations.  Two brothers, Alfred and Arthur Heineman, formed the architectural firm A.S. Heineman & Company in 1909. Though neither brother had any formal architectural training, during the period 1907 to 1923 the two designed 10 grand residences and over 250 smaller bungalows in the Arts & Crafts tradition, in Pasadena and the Los Angeles area.


  Sten-Frenke House, 126 Mabery Road, Santa Monica - 1934 Richard Neutra - Parmelee Geology's services at this historic property included a complete overall evaluation and analysis of existing site conditions and analysis of structure and foundation performance.

       3604 Lowry Drive, Los Feliz - 1954 Kemper Nomland Jr. residence.  Kemper Nowland Sr. trained under Frank Lloyd Wright.  The residence is a post and beam construction design which was built as a "Case Study"  residence (#10).  The Case Study House program (1945-66) was an exceptional, innovative event in the history of American architecture and remains to this day unique. The program, which concentrated on the Los Angeles area and oversaw the design of 36 prototype homes, sought to make available plans for modern residences that could be easily and cheaply constructed during the postwar building boom. The program's chief motivating force was Arts & Architecture editor John Entenza, a champion of modernism who had all the right connections to attract some of architecture's greatest talents, such as Richard Neutra, Charles and Ray Eames, and Eero Saarinen. Highly experimental, the program generated houses that were designed to re-define the modern home, and thus had a pronounced influence on architecture - American and international - both during the program's existence and even to this day. Parmelee Geology was hired to evaluate geologic conditions at the site and to make recommendations concerning restoration and future additions.
