Anza Park, established in August of 2007, is located within Avra Valley adjacent to and west of the Town of Marana boundary. The park consists of approximately 280 acres located along both sides of the Santa Cruz River. This area is a riparian oasis that supports a rich diversity of native plants, birds, and other wildlife, especially as compared to adjacent lands that are biologically depauperate due to decades of intensive agricultural use.
The Floodplain Management Act of 1973 authorized Arizona counties to adopt rules and regulations concerning management of floodplain areas. The Pima County Board of Supervisors, which sits as the Pima County Flood Control District Board of Directors, organized the Pima County Flood Control District on June 5, 1978. The District is responsible for floodplain management activities for unincorporated areas in Pima County (with the exception of national forests, parks, monuments, and Indian Nations) and for the City of South Tucson.
This plan is an action agenda that avoids the long-term strategic planning platitudes and broad generalizations that sound good but do not achieve a great deal. The steps presented in this document are ones we can take in the near term, over the next two years or so, that will provide the foundation for long-term economic growth and stability.
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.
Purpose of this report is to provide a detailed analysis of the runoff characteristics of the Diamond Bell Ranch area.To this end, HEC-HMS models were generated to analyze the runoff under existing watershed conditions.
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.
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.
Offsite drainage impacts the project site from several watersheds whose headwaters lie to the northeast of the project site. This report will address the manner in which the existing offsite and the post-development onsite drainage will be conveyed across this project.
This report is intended to revise the previous watershed hydrologic and hydraulic calculations for the proposed extension of Camino Del Sol Road. This study is necessary because of significant land use changes within the watershed.
This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
