The purpose of this study is to provide the U.S. Fish & Wildlife Service with an analysis that identifies anticipated impacts to each of the covered species and asks the question: How effectively will the County's mitigation lands include the specific habitats of covered species under the Multi-Species Conservation Plan?
Develops the methods for using the National Land Cover Dataset to report change by jurisdictions and land ownership by utilizing an existing dataset. Local GIS-based measures of development based on tax assessor records do not provide direct measures of habitat loss.
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.
Provides a review of eight monitoring efforts in southern Arizona to highlight their accomplishments and to critique their efficacy and overview of important attributes of a monitoring program. This review of projects and successful attributes will provide an assessment framework to better guide the development of the Pima County Ecological Monitoring Program.
The SDCP recognizes the important links between groundwater, streamflow, and vegetation that still exist along some streams and springs in Pima County. Unfortunately, depletion of aquifers has altered streamflow and associated groundwater-dependent vegetation along the Santa Cruz River and other streams. The main purpose of this report is to establish priorities for potential expansion of Pima County's existing aquifer monitoring for groundwater-dependent ecosystems.
Stream flow disappearance due to groundwater pumping, floodplain development, and habitat loss due to erosion have significantly altered the biologically rich and diverse riparian corridors of eastern Pima County. Today, there are new opportunities to recreate our watercourses as a gathering place for people and wildlife.
The Maricopa County Department of Public Health and the Southwest Interdisciplinary Research Center at Arizona State University initiated an evaluation of ASU’s Tobacco-Free Campus policy, which went into effect on August 1, 2013. The purpose of this evaluation is to assess the impacts of this policy on the ASU community and environment. This report summarizes tobacco consumption patterns, norms and perceptions surrounding tobacco use, tobacco litter on campus, and overall benefits of a tobacco-free campus both before and after policy implementation.
In 2006, the Smoke-Free Arizona Act outlawed smoking within most enclosed public spaces and places of employment primarily to reduce the exposure of individuals to harmful secondhand smoke. The purpose of the Maricopa County Smoke-Free Parks Policy Assessment is three-fold: 1) to evaluate the extent and health impact of tobacco usage in public parks; 2) analyze smoke-free parks policies that have been proposed in cities, counties, and states nationwide; and 3) to assess the feasibility of introducing and implementing similar policies in Arizona, and in Maricopa County in particular.
Conservation of the Tortolita Alluvial Fan landscape has been promoted by Pima County and Town of Marana over the past two decades. An interdepartmental team was formed to evaluate flood and debris flow hazards and the potential to create an expanded Tortolita Fan Preserve. This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.
The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
