Hurricane Harvey made landfall on the Texas Gulf Coast in August 2017 causing catastrophic flooding. Harris County is highly vulnerable to flooding, which is controlled in part by a system of bayous that include parks and trails. The petrochemical industry, as well as thousands of documented sources of environmental pollution make recreational areas susceptible to environmental contamination during flood events. Recreational areas and toxic exposure sources were geocoded by subwatershed boundaries and overlaid with the area of Hurricane Harvey inundation. A total of 121 of 349 (36.78%) parks were flooded; 102 of 121 (84.30%) were located in subwatersheds with at least one exposure source. A total of 337 exposure sources (6 Superfund, 32 municipal solid waste, and 299 petroleum storage tanks) in 30 subwatersheds were flooded. Though parks provide flood mitigation and other postdisaster benefits, their susceptibility to environmental contamination should be considered, especially in areas with a large number of toxic exposure sources.

对受飓风哈维洪水影响的休闲区可能的环境暴露进行空间分析，德克萨斯州哈里斯县

2017 年 8 月，飓风哈维在德克萨斯州墨西哥湾沿岸登陆，造成了灾难性的洪水。哈里斯县极易受到洪水的影响，洪水在一定程度上受到包括公园和小径在内的河口系统的控制。石化行业以及数以千计的记录在案的环境污染源使休闲区在洪水事件期间容易受到环境污染。娱乐区和有毒暴露源按子流域边界进行地理编码，并与飓风哈维淹没区域重叠。349个公园中的121个（36.78%）被淹；121 个中的 102 个 (84.30%) 位于至少有一个暴露源的子流域。30 个子流域的 337 个暴露源（6 个超级基金、32 个城市固体废物和 299 个石油储罐）被淹没。
