Evaluates the conservation significance of county-owned properties in Avra Valley, specifically with regard to Priority Vulnerable Species and the Sonoran Desert Conservation Plan.
A diverse community of abundant, native amphibians is persisting along waterways of urban and urbanizing Tucson. Community and government leaders in Tucson support the concept of urban amphibian conservation in principle. Meanwhile, concurrent, commingled plans for infrastructure improvements and ecological restoration along major urban riparian corridors are being developed under leadership from Pima County, City of Tucson, and U.S. Army Corps of Engineers.
Paradoxically, as this work gets underway, it could impact local amphibian populations – temporarily via direct earth-moving impacts, and permanently via elimination of seasonal waters in which amphibians breed. Pima County wishes to minimize these negative impacts, and to learn how to protect, manage and improve habitat conditions for native amphibians. This report describes means by which—despite complex public health issues—such conservation may be possible with proper planning.
This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the Camino De Oeste Wash located in Pima County, Arizona. The objective of the TDN and LOMR submission is provide regulatory discharge rates and floodplain limits along the Camino De Oeste Wash using better topographic, hydrologic, and hydraulic data.
This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the West Speedway Wash located in Pima County, Arizona. The objective of the TDN and LOMR submission is provide regulatory discharge rates and floodplain limits along the West Speedway Wash using better topographic, hydrologic, and hydraulic data.
The purpose of this study is to provide flood and erosion hazard information for Woodland Wash for us in floodplain use permitting and floodplain management.
Because the West Branch area has been left alone, it has a chance to recover and become a part of the larger Paseo de las Iglesias project, and a cornerstone of a more extensive effort at ecological restoration involving the mesic coorridors of Pima County, the Santa Cruz, Rillito, and Pantano.
This study by DR. Philip Rosen stands as one of the most impressive, given the scope of the author's knowledge, and it is one of the most ingenious, given the proposed concepts for restoration and protection of native fish and frogs within the urban Tucson Basin.
