METRO has received a Finding of No Significant Impact from the Federal Transit Administration that signifies METRO has complied with all federal environmental laws. To document any potential environmental impacts of the project, METRO prepared an Environmental Assessment for the Central Mesa extension of light rail on Main Street to Mesa Drive in accordance with requirements of the National Environmental Policy Act of 1969.

One goal of the SDCP was to obtain a permit from the U.S. Fish and Wildlife Service under Section 10 of the Endangered Species Act to enable incidental take of species protected by the ESA in the course of development in Pima County. This report provides the county with the framework to go forward and further its analysis of the final funding costs for a Section 10 Permit.
Provides basic information about the source of surface water in Cienega Creek at the downstream end of the natural preserve, which will contribute to efforts to conceptualize and implement effective land management proposals for the SDCP. Study results indicate that the surface flow or subflow from Agua Verde Creek do not significantly influence the water in the Cienega Creek.
Conducted for the Pima County Flood Control District by the Pima Association of Governments in order to determine if stormflows on the Cienega Creek have changed over time when analyzed in terms of frequency, volume, and seasonallity. In a data search that extends back to the 1950s, they were able to determine the daily mean flow, the flows over base, and the annual peak flows of the Cienega Creek.
Concerns research into the origin of water sustaining the Bingham Cienega. For purposes of long term management, we need to understand what the source of water is for the various riparian areas.
The purpose of this project was to compile information on groundwater withdrawals and surface water diversions near perennial streams, intermittent streams, and shallow groundwater areas previously identified by PAG for the SDCP. The information could be used to prioritize future investigations of potential impacts of these withdrawals and diversions on riparian and aquatic habitats for the SDCP.
This document and the Geographic Information System file that is now a part of the County library of over 1000 coverages, gives the scientific community access to mapping that better differentiates perennial, ephemeral and intermittent watercourses, and provides more comprehensive coverage of shallow groundwater sources. This data is significant because riparian habitat is one of the most important and least protected of the habitat types in Pima County.
