Given the inevitable transportation changes associated with impending growth in Pinal County, there was a need for a method to assess how corresponding emissions changes might affect PM10 and Ozone concentrations in the county and at the monitor sites. The overall objective of the project was to develop methods or models that could be used in Pinal County to adequately address air pollution issues in the County.

This report and the accompanying Geographic Information System (GIS) datasets summarize the results of the workshop held in Florence, Arizona in 2010. At this workshop, stakeholders representing a broad range of organizations and interests identified and mapped the locations of important wildlife linkages across Pinal County. This report provides background information on the importance and benefits of conserving wildlife linkages for both people and wildlife in Pinal County and describes the methods used during stakeholder workshops and in developing the accompanying GIS products. It includes a series of maps generated from the digitized stakeholder data that depict the general locations of wildlife linkages and potential barriers to wildlife movement within Pinal County. The maps are followed by tables with descriptive information about the habitat areas each linkage connects, the species each linkage serves, and known threats and potential conservation opportunities associated with each linkage.

For more than a year, a team of consultants, led by Poster Frost Associates, worked with the Pima County Board of Supervisors, Pima County staff, the Canoa Ranch Community Trust and Oversight Committee, and local stakeholders to develop a Master Plan for the Historic Canoa Ranch. Since purchasing the 4,800 acre Canoa Ranch, south of Green Valley, in 2001, Pima County has embarked on a number of projects at the ranch to preserve and protect the valuable natural and cultural resources. The preservation and restoration of historic buildings were completed in early 2013, and efforts to protect important habitat and restore natural systems continue today. The Master Plan represents an important milestone towards the goal of making the Canoa Ranch a public site where its rich history can be understood and appreciated by visitors.

This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
