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.
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.
Identifies key potential threats and stressors to vulnerable species in Pima County, and to the biological and hydrological resources that support these species. Emphasis has been placed on identifying the specific components of past, existing, and proposed land and water uses that pose the greatest potential threats over the next 30 years to focal species and special habitats, plant associations, and communities.
Two studies that describe the progress of riparian mapping that is being developed as part of the Sonoran Desert Conservation Plan.
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?
A preliminary analysis that has been drafted in conjunction with participating federal agencies. Land managing entities provided information and later a detailed review of fact sheets that summarize each reserve in terms of its size, ownership, authorizing documents, land use activities, priority vulnerable species, exotic and non-native species, baseline information, GAP status, acquisitions, management plans, research, monitoring and recovery programs. The study proposes eight Reserve Management Areas that include land managers who could work together across administrative boundaries.
A great deal of additional information is now available regarding the area designated as containing biological resources as indicated on the "purple map" attached to the March 19, 2001 report. The Science Technical Advisory Team has worked on differentiating the resources within this area and assigning biological resource values to refine the SDCP and allow informed judgements regarding future uses of lands within the areas of biological sensitivity.
