Highlighting the Potentials of Gene C. Reid Park, Tucson, AZ, as a Tool for Flash Flooding Control

Abstract

This study investigates the effectiveness of Gene C. Reid Park in Tucson, AZ, for managing flash flooding, comparing it with Ormsby and Santa Rosa Parks also in Tucson, AZ. Flash flooding poses a significant environmental risk in Tucson, AZ, leading to extensive damage and fatalities. The study employed purposive sampling and a mixed-method approach, which included case studies of the parks, the quadrant method, and the rational model used to calculate the proportions of vegetation and impervious surfaces and estimate runoff for each location. Data analysis was conducted using regression analysis. Gene C. Reid Park showed a notably lower runoff rate of 310.65 ft 3 /s, in contrast to Santa Rosa Park’s 1963.5 ft 3 /s and Ormsby Park’s 1859.07 ft 3 /s. The lower runoff rate observed in Gene C. Reid Park is due to its abundant vegetation and sufficient park facilities, demonstrating its effectiveness as a “sponge” during flash flooding. Results indicate that urban parks designed for flood mitigation should prioritize increasing green spaces and incorporating features that effectively absorb floodwaters. This study contributes to a better understanding of the roles of urban parks in flood management and offers valuable insights for sustainable urban planning in Tucson and other cities facing similar challenges.
