Arizona State and Local Government Documents Collection
The State and Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.
The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog. For additional assistance, Ask A Government Documents Librarian.
Publications issued by the Morrison Institute for Public Programs at Arizona State University are also available in PRISM, in the Morrison Institute for Public Policy - Publications Archive collection.

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.
Ten watercourses in eastern Pima County were selected because, except for one, each has a 100-year discharge in excess of 10,000 cfs, and each is located within an urbanized or urbanizing area, or in an area where an increasing number of permits are being sought to develop in the floodplain.
This memorandum describes (1) the potential applicability to Pima County of a national initiative to institute reforms in floodplain management; and (2) an assessment of the effectiveness of Pima County's Riparian Habitat Mitigation Ordinance (attachment). An inter-departmental team was formed to formulate specific proposals for consideration as part of the Riparian Protection Element of the SDCP and the major plan amendment to the County's comprehensive plan.
Arizona's fish story begins in 1904 with the publication of Morton Chambrlain's "Survey of Arizona Fishes", the first detailed study by an aquatic biologist of the area. He was able to count sixteen native species in Arizona. Today more than half are either extinct or listed as threatened or endangered, and most of the rest are considered to be imperiled. In Pima County, we count more extirpated native fish than remaining residents. The story, absent a fairly dramatic change in circumstances, will end with the extirpation or extinction of all native fish in the region. This report provides an opportunity to change the circumstances of aquatic and riparian systems in eastern Pima County.
