This leads to decreased water infiltration, modified water flows, and introduced contaminants into the ocean. Flooding, traffic accidents, property damage, increased safety and health risks, and environmental damage can occur as a result. Green infrastructure and natural treatment systems are emerging as a supplementary stormwater management strategy. However, no one has ever quantified or placed economic value on the variety of ecosystem services provided by different types of natural treatment systems. USC Sea Grant funded research to analyze the ecosystem services (e.g. flood control, ground water recharge, improved water quality, biodiversity, pollination, climate regulation, recreation, outreach and education, aesthetics) provided by the natural treatment systems in Los Angeles. With this type of analysis, these systems could provide a unique opportunity for customization and optimization to maximize benefits for human well-being in urban settings, including localized flood control at the house or neighborhood level.<\/span><\/p>\n\n\n\n<\/div>\n      \n      \n    <\/div>\n  \n  \n  \n\n  <\/div><\/div>\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--rich-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--rich-text\"\n    \n      >\n\n    \n      \n<div class=\"f--field f--wysiwyg\">\n\n    \n  <h3><b>Key Results<\/b><span style=\"font-weight: 400;\">:<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Large database of data on ecosystem services provided by different types of natural treatment systems in Los Angeles, including bioretention systems, infiltrations systems, permeable pavements, dry ponds and wells, and treatment wetlands.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Calculated economic value of these ecosystem services <\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Project Impacts &amp; Application:<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Presentations of results at University of California Office of the President, Multicampus Research Programs and Initiatives meetings and the 2019 American Chemical Society National Meeting<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Data being made publicly available via an online database<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Principal Investigator:<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Lisa A.
