Originally, the purpose of the study was to obtain either a Letter of Map Revision or a Physical Map Revision from the Federal Emergency Management Agency. Unfortunately, during the initial stages of the investigation, it became apparent that FEMA's guidelines for these types of map revisions could not be accommodated, primarily due to flow-distribution conflicts.

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.

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.

This report is a reexamination of visitor data first reported in the multi-year "Survey of Visitors to Arizona’s Tribal Lands," which was commissioned by the Arizona Office of Tourism and conducted in 2004-05 by the Arizona Hospitality Research and Resource Center at Northern Arizona University. That study, released in December 2005, analyzed visitor data collected for eight Arizona American Indian tribes and presented that data in aggregate for all tribes. This report, on the other hand, disaggregates that original database to take a more in-depth look at visitor patterns at Rural versus Metro tribes in Arizona.

Generally, this second study found that visitors to Rural and Metro tribes in Arizona are similar in many ways – parties of two persons; parties composed largely of family members; similar educational and income levels; private vehicles as travel mode; similar sightseeing and cultural/heritage activities; similar information sources; relatively high satisfaction levels; and, many similar shopping purchases. The survey also found some significant differences, however, including the following: Travel parties visiting Rural tribes contained more children, more Arizona residents, and had higher numbers of repeat visitors. Visitors to Rural tribes were also more likely to describe the tribe as their main destination; were more likely to engage in recreation and outdoor activities; stayed longer; and, consequently had higher spending. Visitors to Metro tribes were slightly older and visited the tribe as one stop on a longer trip. Visitors also reported slightly higher satisfaction levels at Metro tribes.

A survey of visitors to Native American tribal lands in Arizona was commissioned by the Arizona Office of Tourism and conducted by NAU’s Arizona Hospitality Research & Resource Center in 2004-2005. This research constituted the first major study of visitors to Native American tribes in Arizona and possibly in the Southwest. This final report, Survey of Visitors to Arizona Tribal Lands, provides first-ever baseline visitor data, presented in aggregate for the eight participating Arizona tribes. The study found that visitors to these Native American tribes in Arizona are slightly older, have higher annual incomes, stay longer, and have higher daily expenditures (for lodging, shopping and entertainment) than Arizona visitors generally. Visitors to Arizona’s tribes are also more interested in cultural and historic activities, shopping for arts and crafts, educational experiences and sightseeing than are visitors overall. They are also highly satisfied with their visits to Native American tribal lands.
