Fort Lowell was a supply base for the United States Army “Apache Campaigns” between 1873 and 1891. Following abandonment of the fort in 1891, settlers moved in and used some fort buildings as residences, or stripped the buildings of useful materials. By the 1930s, much of the fort had fallen into disrepair or had been sold off. Eventually, the City of Tucson acquired a large portion of the old fort which became what is today’s “Fort Lowell Park.” A 5.2 acre (“Adkins”) parcel of the former fort containing several original adobe buildings was still in private ownership, and the 2004 County bond election passed a proposal to acquire the land and preserve the historic resources.

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 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.
