The lot is on the park acquisition list. The old railroad grade is an easement to 

 the Mclsaac Ranch west parcel and the two dwellings there. 



4. Historic Significance of Mclsaac Ranch 



The Mclsaac Ranch is significant as an example of an early Swiss-owned 

 dairy ranch in the Lagunitas Creek area. The farm house is unique to the area 

 and includes a pioneer portion attached. The hay barn is unlike any other 

 remaining in the area, and of fair structural integrity. The old house on the 

 hill above Tocaloma is a pioneer structure in use for more than 120 years. The 

 Mclsaac Ranch and neighboring Zanardi Ranch are the last of some six dairy 

 ranches that once occupied this section of Lagunitas Creek which retain their 

 historic integrity. 



The Tocaloma Bridge has regional significance in transportation and 

 architecture, as the best example of a J. C. Oglesby bridge on the important 

 "town-to-country" road, Sir Francis Drake Highway. The bridge has long been a 

 landmark to Bay Area residents and was an important link in the county-wide 

 transportation system.
