remain on the south face; a deck was recently added to this side, affording a 

 sweeping view over the ranch and valley. The interior has seen basic 

 alterations, although it retains its original layout of three bedrooms (two 

 upstairs), living room, kitchen and dining room. The house is very old and in 

 poor condition. Because of alterations it possesses only fair historic integrity. 



g. Water Tank 



This water tank, twelve feet square and eight feet deep, sits on the slope 

 above the corrals. The underground portion is concrete and covered with an old 

 board and batten tank house that may be up to 100 years old. The roof is 

 pyramidal with a vent cupola and decorative spike at the top. It is in fair 

 condition, and possesses good historic integrity. 



h. Tocaloma Bridge 



The Tocaloma Bridge, long a landmark on Sir Francis Drake Highway, 

 was designed by Marin County surveyor John C. Oglesby and constructed in 

 1927. The bridge crosses Lagunitas Creek at Tocaloma before the long grade 

 towards Olema. The new highway was touted as both an important farm route 

 and a pathway to scenic west Marin County for an increasing number of 

 motorists. Financed by a 1925 bond issue in the county, the Tocaloma Bridge 

 was the most spectacular of six large bridges built during the project, 1926- 

 1930. The reinforced concrete arch bridge is unique to the west county, and 

 only one similar bridge exists in the county. The bridge was bypassed in 1962 

 and abandoned, the property reverting to the Mclsaac family. The bridge has 

 cracks and damage to the concrete guard rails, and will require structural study 

 by qualified engineers to determine its condition. Further study of the history 

 of this bridge is recommended. It possesses good historic integrity. 



i. Railroad Grade 



The original railbed of the North Pacific Coast Railroad and its 

 successors, the North Shore Railroad and the Northwestern Pacific Railroad, 

 passes through the property along the west bank of Lagunitas Creek. Built by 

 Chinese labor in 1874 and widened for standard gauge tracks in 1920, and
