This inventory includes emissions of coarse particulate matter <10 µm in diameter (PM10), fine particulate matter < 2.5 µm (PM2.5), nitrogen oxides, sulfur oxides, and ammonia. Emissions are calculated for both Maricopa County and the PM10 nonattaiment area. Annual totals as well as typical daily emissions are provided for all source categories.
Information on the efforts of the Ambos Nogales Air Task Force as part of the Border 2012: U.S.-Mexico Environmental Program to improve environmental quality in the area along the Arizona Sonora border.
The depiction of a historical-period property on an early map, whether a house, a ranch, a mining prospect, or an irrigation canal, is often the earliest (and sometimes the only) evidence that cultural features once existed in a particular place. Statistical Research used early maps as a regional preservation-planning tool by systematically examining a group of early maps of the county for depictions of cultural features. The typology will be used to plot the sites, distinguished by type, on a single map (or possibly on a series of maps) to be digitized by Pima County and incorporated into its GIS database.
This report is one of several from Statistical Research Inc. written to develop the Cultural and Historic Resources Element of the Sonoran Desert Conservation Plan. Divided into four parts, the report summarizes available information that reflects the experience of (1) ancient peoples of Southern Arizona; (2) indigenous peoples; (3) non-indigenous peoples of the historical period; and (4) Pima County today.
On March 2, 1999, the Board of Supervisors of Pima County, Arizona adopted the Sonoran Desert Conservation Plan. This Plan is the largest and most comprehensive regional multi-species conservation plan in the United States. These memorandums of understanding record the agreements made with cooperating agencies.
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.
