Mr. Proudfoot, the leading pygmy-owl biologist in the United States, has worked for the last two years to gather and analyze the data that allows us to address issues regarding the genetic viability of ferruginous pygmy-owls in Arizona and to establish a framework for future management efforts. The two major questions addressed are (1) do populations of concern lack genetic variation relative to putative healthy populations, and (2) how unique are geographically distinct populations within a species of special concern?
Flooding and erosion within the Ranch Estates subdivision during the 2007 summer monsoon season raised the concerns of homeowners. This study addresses the impact of recent improvements in the drainage area upstream; provides updated flood-hazard mapping for the area, and identifies mitigation measures that could be implemented by the affected homeowners to address their flood/erosion hazards.
This Technical Data Notebook has been prepared in support of a Letter of Map Revision application for a portion of the Friendly Village Wash. It includes detailed hydrologic and hydraulic analyses performed to determine proposed regulatory discharge rates at key locations along the Wash, and to determine floodplain limits.
