Water quality is an important issue in the alternatives analysis of the SDCP and as a component of the Environmental Planning Element of the Comprehensive Plan that requires analysis, policies and strategies to address anticipated effects of plan elements on air quality, water quality and natural resources associated with proposed development under the Plan.
Report is a review and compilation of existing data on water quality requirements of eight aquatic species. By identifying the water quality requirements of priority vulnerable species of concern, and assessing the quality of water that serves or might serve as potential habitat, we begin to understand which sources will support priority aquatic species identified by the SDCP.
Compiles water quality data for the streams that have been identified as priorities and assesses land uses and potential pollution sources that might impact the water quality of the highest priority aquatic habitats.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers is being published. This study discusses water resources in the context of the alternatives being considered to date.
The Arizona population of the cactus ferruginous pygmy-owl was listed as an endangered species under the Endangered Species Act in 1997. Historical records and recent surveys definitely show a decline of species. There is a wealth of historical information out there and it still trickles in every day.
The historical range of the ferruginous pygmy-owl included areas of southern Arizona, southern Texas extending south along both coasts in Mexico, through Central America into the southernmost population in Argentina. However, over the past 150 years urban and agricultural expansion within the United States has reduced its population to a few isolated pockets of uncertain stability.
Most of the owls until just the last couple of years have been found in residential areas in northwest Tucson. It take a lot of cooperation on the parts of private residents to help get the work done. These are incredible little birds that fill an interesting role in the environment since they are more diurnal versus nocturnal. Our objective is to gather as much information as fast as possible to feed into the process to make this County plan based on the best available science that we have.
Pima County contracted with Arizona Game and Fish Department to conduct telemetry analysis and gather information that would lead to effective conservation and recovery initiatives for the cactus ferruginous pygmy-owl. During 1997, banded birds were monitored. Beginning in 1998 and during 1999, pygmy-owls were radio-marked with backpack transmitters and followed on foot or by vehicle.
Brings together the findings of previous reports and suggests policies to address water quality issues in Pima County.
Pima Association of Governments has worked with County staff for over two years on a series of riparian and water resource studies related to the SDCP and Comprehensive Land Use Plan. The three studies found within this document represent the final versions of (1) Water Quality in Pima County; (2) Water Quality of Priority Streams in Pima County; and (3) Water Quality Requirements of Native Aquatic Species in Pima County.
