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.
Chronicles some of the changes in the Pima County Zoning Code since 1953 and summarizes the comprehensive plan, the zoning code, and the building codes.
The study details the direct and indirect impacts of roads on natural resources, including direct mortality and loss of habitat, physical changes to the topography and hydrology of an area, impacts to habitat, noise, light and other types of pollution, and habitat fragmentation.
Provides a thoughtful and timely assessment of how Pima County's practices and policy proposals in land use stand up under the test of nationally recognized principles of smart growth.
Summarizes applications placed in the newspaper and mailed directly to Steering Committee members to solicit Land Panel membership. 177 applications were received and compiled. Includes a suggested alternative for selecting Land Panel members.
A study on the last five years of rezoning activity in eastern Pima County for the Suburban Ranch Zone, Rural Homestead Zone, and Rural Residential Zone. This indicator of development activity does not include activity in the incorporated areas or the land that was rezoned and often platted.
