Letting It Soak In: Infiltration and Water-Based Recreation Inside Irwindale's Olive Rock Pit as a Climate Adaptive Model for Drought and Flooding in the San Gabriel River's Alluvial Fan Region of Los Angeles County
Los Angeles is synonymous with being the birthplace of young trends, a cultural hub that ripples outward. It is also known for its beaches and historic presence of aquatic recreation earning it the title “the swimming pool capital of the world”. The encroachment of climate change, however, poses risks to aquatic and water-based recreation. Beaches have increasingly been closed due to harmful algal blooms and toxic water conditions. The recent wildfires in the Pacific Palisades region in 2025 raised concerns along the coast due to contaminated runoff. As temperatures get hotter and drier, spaces where people can interact with water become scarcer. Vehicular congestion in the car-centric region of Los Angeles prevents easy access to coastal waters for those living inland, yet the effects of climate change felt through record-breaking temperatures, drought, and torrential rains have compelled local officials to update their recreational plans with a focus on flood and water conservation. Upon analysis of these plans, current and proposed recreational adaptive strategies appear to remain predominantly passive towards opportunities for human-water interaction and instead focus strategies such as bioswales, rain gardens, and permeable surfaces along linear parks and trails while continuing the binary between stormwater infrastructure and immersive water-based recreation as two separate entities. Most would argue that conserving water is the more logical way of coping with a drought, however, developing an understanding human-water relationships through immersion is crucial for water conservation in the long run through a development of attachment and sense of place as opposed to temporary resolutions in the form of top-down approaches to emergency events that leave room for inequality and detachment. This thesis seeks to blur the boundary between stormwater management infrastructure and public recreation by investigating how a mutual integration of aquatic recreational design, stormwater conservation, and flood control systems address regional conservation efforts by asking how can the integration of aquatic recreation and flood control systems serve as a model for water conservation in alluvial fans and respond to the flood and drought prone future of Los Angeles through the design of public recreational space, establishing opportunities for human-water interaction that promote an education on systems, climate and cultural awareness, as well as public health and wellbeing.
