The Late Spring Secondary Precipitation Maximum in the
Interior Pacific Northwest results from a complex system of climatic
controls. The Secondary Maximum is most strongly developed over the
high plateau of Oregon immediately in the lee of the Cascade
Mountains. Local topographic
organization exerts strong control
over the magnitude and...
Existing land use controls have not effectively achieved
the goals of resource protection and preservation. Prime agricultural

for this paper were conditional use permits, special exceptions,
and variances. Philomath, Corvallis, and Benton
County, Oregon were the jurisdictions used for the study area.
It was determined that the exceptions to the...
When land use issues are voted upon directly by the people, or by
the legislators who represent them, the outcome often reveals a discrepancy
based on population density. Urban-suburban areas tend to
support regulation, while rural areas tend to oppose it. The residents
of Clackamas County have voted on two...
The aggregate industry is responsible for the extraction and production of crushed stone, sand, and gravel— the literal building blocks of our society. Across the U.S. there are tens of thousands of quarries and sand and gravel pits, the majority of which are left abandoned or with minimal reclamation efforts....
