Historically, Pima County has recorded several residential concerns, detailing this area as a reach of wash with severe flooding problems. The purpose of this report is to present the engineering analyses of four alternative remedial flood-control measures.
This report and the accompanying Geographic Information System (GIS) datasets summarize the results of the workshop held in Florence, Arizona in 2010. At this workshop, stakeholders representing a broad range of organizations and interests identified and mapped the locations of important wildlife linkages across Pinal County. This report provides background information on the importance and benefits of conserving wildlife linkages for both people and wildlife in Pinal County and describes the methods used during stakeholder workshops and in developing the accompanying GIS products. It includes a series of maps generated from the digitized stakeholder data that depict the general locations of wildlife linkages and potential barriers to wildlife movement within Pinal County. The maps are followed by tables with descriptive information about the habitat areas each linkage connects, the species each linkage serves, and known threats and potential conservation opportunities associated with each linkage.
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 study proposes to reduce flood damages from both Tanque Verde Creek and offsite flows, as they affect the Fortyniner's Country Club Estates and the Arbor Vista subdivisions.
The purpose of this report is to assist the Pima County Board of Supervisors in assessing whether the Black Wash area requires area-specific flood control policies.
The purpose of the study is to identify existing flooding problems for fifteen homes adjacent and west of Holladay Street which have experienced flooding in the past three years. A 1991 follow-up report is included that corrects an error in the earlier report's estimation of the split flow quantities at the intersection.
Millstone Manor #6 is a subdivision that was recorded in the mid-1950's. All records indicate no engineering took place with regards to potential for drainage improvements. This report will address what the natural floodprone areas are and will recommend how future permits should be processed.
Covers an area in southeastern Pima County that drains the Arivaca Creek watershed. The purpose of the report is to estimate peak discharge for the 50 year storm frequency event, utilizing the rational method (Q=CiA). This method pre-dates that outlined in the Hydrology Manual for Engineering Design and Floodplain Management within Pima County, Sept. 1979, and is considered less accurate. It is recommended that this report be archived and discontinued for use for regulatory purposes.
The Arizona Game and Fish Department held four Wildlife Summits to obtain input from their stakeholders into the development of the Comprehensive Wildlife Conservation Strategy. Stakeholder groups invited to participate in the Summits included Department constituency groups, special interests, local governments, Native American tribes, interagency cooperators, and the general public. This report combines the votes from each of the four Summits into one database for analysis. The results for each individual Summit are attached as separate reports. Comparisons are made in this combined report to show differences between the results of individual Summits. The combined results have also been analyzed to determine if there were any significant differences in opinions of the various stakeholder groups. Demographic breakdowns of the individual Summit results are not included in the separate reports because they would not be statistically valid given the small number of participants at each Summit. Participant comments are included in the
individual Summit reports.
