About the Study
A general boundary of the study area is described in the authorizing legislation for the special resource study. This boundary does not define any kind of management or jurisdiction; it simply defines the resources that the NPS will evaluate through the study process.
As described in the legislation, the study is to include, “...the area known as the Rim of the Valley Corridor, generally including the mountains encircling the San Fernando, La Crescenta, Santa Clarita, Simi, and Conejo Valleys in California.”
Numerous projects and initiatives are associated
with the name “Rim of the Valley.” However, the most widely used definition is the area defined
by the Santa Monica Mountains Conservancy (SMMC). As this area encircles the valleys described in the
authorizing legislation, the SMMC’s Rim of the Valley area is generally being used to guide definition
of the study area.
