The objective of this Technical Data Notebook is to provide 100-yr peak discharges at a Concentration Point for the Unnamed 02 and 03 Washes, 100-yr floodplain boundary and erosion hazard information, using the most up-to-date topographic, hydrologic, and hydraulic data. This is a local study and has not been submitted to FEMA.
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.
This Technical Data Notebook has been prepared in support of a Letter of Map Revision submittal to amend the 100-year floodplain, or Special Flood Hazard Area associated with Finger Rock Wash in Pima County, Arizona. The purpose of this LOMR application is to revise the effective Flood Insurance Rate Map SFHA boundaries based on updated and more detailed information. No new hydraulic structures are present within the study limits.
This report documents the existing drainage conditions related to Silverbell Trails Estates roadways and 100-year flow depths and includes qualitative and quantitative analyses of the existing hydrologic and hydraulic conditions.
The purpose of this study is to determine the hydrologic and hydraulic impacts of the Aspen Fire of the summer of 2003 on the Sabino Canyon and Carter Canyon watersheds, which are in the vicinity of the Town of Summerhaven, located on Mount Lemmon in the Santa Catalina Mountains, Arizona.
This request for a Physical Map Revision is for a reach of Camino de Oeste Wash from Foret Road to Camino De Oeste Road. This PMR is to reflect improved topographical data available subsequent to the Flood Insurance Study of this area, and to establish base flood elevations for the floodplain.
This report was prepared to document surface water hydrology and floodplain conditions in accordance with current standards of practice. This information is intended to support issuance of building permits, re-approval of construction drawings to current standards, and issuance of floodplain use permits, if needed.
Pima County is now finalizing the long-awaited Multi-species Conservation Plan, which, if approved by the U.S. Fish and Wildlife Service, will streamline public-sector and private-sector development compliance with the Endangered Species Act while protecting endangered species and their habitats. In the coming months, the public will have a chance to comment on the MSCP through the U.S. Fish and Wildlife Service’s formal public comment process before it goes to the County Board of Supervisors for final adoption.This report reviews the history of the MSCP, its relationship with the award-winning Sonoran Desert Conservation Plan, what benefits the MSCP will bring to the community, and what obligations the County, developers, and the taxpayers will have over time. The report also highlights other benefits of conservation actions undertaken by Pima County, including economic, recreation, and health benefits.
