Reports on the development of a reconnaissance level numerical groundwater model of the Davidson Canyon and Cienega Creek watersheds. Includes recommendations for data that must be collected prior to completing environmental analyses for the proposed project.
One of the most pressing growth related problems is the proliferation of wildcat subdividing, or lot splitting. It is generally defined as the proliferation of new residential parcels without the benefit of subdivision regulation. Often these areas are devoid of any basic infrastructure, standard environmental regulation, subdivision standards, or infrastructure requirements. This report addresses seven areas of concern.
Elements of the comprehensive plan now include planning for water resources that must address the currently available surface water, groundwater, and effluent supplies and provide an analysis of how the future growth projected in the county plan will be adequately served by the legally and physically available water supply. This is the first study to be issued as part of the Water Resources Element and identifies a number of measures that can be taken to conserve water, including measures that can be taken by Pima County in the form of ordinance adoption.
Provides an indication of why unregulated development offers so little benefit to the tax base by describing, briefly, the fiscal tax base impact of the unregulated lot split issue at the community and watershed level.
This memorandum is intended to provide an indication of why unregulated development offers so little benefit to the tax base by describing, briefly, the fiscal tax base impact of the unregulated lot split issue at the community and watershed level.
Pima County's level of service standards tend to be low compared to other jurisdictions and compared to benchmarking information. This is not a surprising result, given the County's expenditures per capita are far below those of county governments in other parts of the United States that are experiencing growth pressures. A concurrency management system will bring service levels in line with population demands.
Apache trout is a federally threatened salmonid native to headwaters of the Little Colorado, Black, and White rivers in east-central Arizona. Decline of Apache trout to threatened status was attributed to over-fishing, habitat degradation and negative interactions (predation, competition and hybridization) with introduced nonnative salmonids. Although over-fishing is no longer considered a threat, habitat degradation and negative interactions with nonnative salmonids continue to threaten Apache trout, and it is towards these threats that recovery actions are directed. While barrier construction began in 1979 and livestock exclusion began in the mid-1980s, the efficacy of these recovery actions at increasing Apache trout abundance and improving habitat condition had not been evaluated. We therefore initiated a study to evaluate the efficacy of riparian fencing and barriers.
