The objective of this Technical Data Notebook is to provide 100-yr peak discharges at Concentration Points for the Unnamed Wash 12, 100-yr floodplain boundary and erosion hazard information, using the most up-to-date topographic, hydrologic, and hydraulic data.

This Technical Data notebook has been prepared to study a portion of the Pegler Wash located in Pima County, Arizona. The objective of the TDN is provide regulatory discharge rates and floodplain limits along the Pegler Wash using better topographic, hydrologic, and hydraulic data.

These studies was performed to provide drainage, flood, and erosion hazard information for Hacienda del Sol Wash and an unnamed wash running along Hacienda del Sol Road. Topographic, hydrologic, and hydraulic analyses were performed to determine drainage conditions.

The purpose of this study is to provide uniformity in how building permits are processed and development is regulated within sheet flood areas in order to ensure that improvements are adequately protected from flood hazards.

This report examines how effectively Pima County’s natural open-space acquisitions have addressed priorities for conserving species’ habitats and landscape features identified in the Sonoran Desert Conservation Plan. The scope of this study is beyond the County's Multi-Species Conservation Plan, which is a subset of the overall Sonoran Desert Conservation Plan.

The purpose of this study is to provide the U.S. Fish & Wildlife Service with an analysis that identifies anticipated impacts to each of the covered species and asks the question: How effectively will the County's mitigation lands include the specific habitats of covered species under the Multi-Species Conservation Plan?

Develops the methods for using the National Land Cover Dataset to report change by jurisdictions and land ownership by utilizing an existing dataset. Local GIS-based measures of development based on tax assessor records do not provide direct measures of habitat loss.

The purpose of this study is to provide flood and erosion hazard information for Soldier Canyon Wash for use by the District in floodplain use permitting and and floodplain management.

This study identifies the drainage and flooding hazards within the watershed and develops alternatives to address those hazards. It is a comprehensive study that estimates flood and erosion potential, maps watercourses, identifies existing and potential problems and develops preliminary solutions and standards for sound floodplain and stormwater management.
