This study from the citizens of the Arivaca community proposes to establish an Arivaca Resource Management Zone, where a atwo level management plan integrates the otherwise fragmented land use and water policies of the various regulatory agencies. The Arivaca watershed contains one of the last remaining cienegas and perennial streams in southern Arizona. These unusual water features exist because the area is still in a state of balance, where annual water consumption is less than the natural recharge replenishing the aquifer during years of average precipitation.
Through the conservation of ranchland in eastern Pima County, the metropolitan urban boundary is better defined, vast landscapes of open space retain their integrity and the heritage and culture of the West is preserved.
To prevent unwanted urban sprawl and unregulated development, it is most important that Pima County encourage and retain viable ranches. Ranching is a significant land use that has served to protect our natural open space, and it continues to be an important traditional industry that has shaped the rural landscape.
A report shall be prepared at least every five years beginning in 1985 and shall indicate the past efforts of the district in eliminating or minimizing flood control problems and state the planned future work of the district to eliminate or minimize flood control problems.
The 2009 Comprehensive Floodplain Management Plan and Program is intended to be used as a general guide for future decision-making in District activities. The Plan aims to present adequate background information to aid District staff in prioritizing areas for future studies and projects. The Plan identifies historic flooding events, reviews the District's efforts to solve flooding problems, and formulates five-year plans to reduce flooding through flood control project construction, floodplain identification, and planning programs throughout the county.
The Groundwater Cleanup Task Force has examined various aspects of Arizona's cleanup programs as well as similar programs in other states and on the federal level. Its members have debated these issues in detail, and present this report as a summary of the Task Force's work and recommendations.
Four maps showing vacant parcels, improvements on 5+ acres outside the Eastern Pima County Conservation Lands System. Map 1: Less than $10,000 -- map 2: Less than 1$15,000 -- map 3: Less than $20,000 -- map 4: Less than $25,000.
To facilitate discussion about which species might be considered for protection, a series of in-depth interviews were conducted with members of the local science community who have expertise in the areas of birds, fish, invertebrates, mammals, plants and plant communities, and reptiles and amphibians.
Compiles information on plants and animals that are already recognized by the federal government as imperiled species, species which have been extirpated, and a much larger number of species that are in decline either locally or nationally. Descriptions of status, location, distribution, and habitat needs are presented for each species proposed. The report also considers vegetative communities, their history of decline and modification, and recommends priorities for their protection.
Summarizes four documents that reflect some of the work that Pima County and Department of Interior staff, along with the science and Geographic Information Systems technical teams, have created to develop the biological component of the Sonoran Desert Conservation Plan.
