It makes sense to begin first by introducing yourself to other members of the class - as you will find this network of professionals to be a very rich resource for your continued learning journey.\r\n\r\nWe are excited to begin this learning experience by clarifying some basic definitions for Green infrastructure (GI) and explore the fundamentals of GI. We begin with the assumption that urban centres face three main challenges with regard to water management: storm flooding, water pollution and water shortages. Urban areas around the world are working to reduce runoff and pollution, and also to restore downstream ecologies. This occurs when low impact development methods are integrated with grey infrastructures, large-scale flood control projects and ecological rehabilitation. There are some promising experiments taking place worldwide with Green Infrastructure systems to support these efforts.\r\n\r\nGreen infrastructure is a broad category that includes both natural ecosystems and engineered systems created to mimic the natural functions and services provided by healthy ecosystems to human communities. Green infrastructure is referred to using various terms including natural asset infrastructure, low-impact development, green rainwater infrastructure, blue-green infrastructure, etc. Each term has been developed to describe a system focused on distinct outcomes and often on a particular scale. When you read the article by Fletcher, it will give you a sense of how these terms are used and how they have evolved over time. For the purposes of this course, we will focus primarily on enhanced and engineered green assets, particularly as they relate to water.\r\n\r\n<a href=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-3.04.31-PM.png\"><img class=\"alignnone wp-image-117 size-full\" src=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-3.04.31-PM.png\" alt=\"\" width=\"891\" height=\"445\" \/><\/a>\r\n<h6>Source: <a href=\"https:\/\/mnai.ca\/media\/2019\/07\/SP_MNAI_Report-1-_June2019-2.pdf\" target=\"_blank\" rel=\"noopener\">https:\/\/mnai.ca\/media\/2019\/07\/SP_MNAI_Report-1-_June2019-2.pdf<\/a><\/h6>\r\nGI is considered a strategy for mitigating the harmful impacts of urban stormwater runoff and has been implemented in cities around the world. Also referred to as Green Rainwater Infrastructure (GRI) or Low-Impact Development (LID), these systems have the capacity to capture, infiltrate, treat, and convey urban runoff safely into the natural environment to avoid pollution, flooding, and many other unintended consequences. GI systems have been found to eliminate over 90% of pollutants that were commonly found in roadway runoff by way of infiltrating runoff through soils and plant tissues. In addition to natural GI, enhanced and engineered GI systems \u2013 often in the form of green roofs, bioretention cells, and permeable pavements \u2013 are capable of retaining 50-70% of annual stormwater runoff when maintained properly.

GI systems vary significantly in their purpose, capacity, and complexity \u2013 however, all are assets that require ongoing strategic asset management. While green infrastructure is anything that uses biological systems and ecosystem functions to provide a service to humanity, effective green infrastructure does so without degrading those systems or functions. Here are some of the systems we will talk about in this course and what they are designed to do:\r\n<h3>Green Infrastructure and Catchment Scale Effects<\/h3>\r\n<a href=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-25-at-2.45.46-PM.png\"><img class=\"alignnone wp-image-119 size-full\" src=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-25-at-2.45.46-PM.png\" alt=\"\" width=\"691\" height=\"342\" \/><\/a>\r\n<h6>Source: <span class=\"table-caption__label\">Table 1. <\/span>Summary of Common Low-Impact Development (LID) Practices by <a id=\"a1_Ctrl\" class=\"author-name accordion-tabbed__control\" role=\"button\" href=\"https:\/\/onlinelibrary.wiley.com\/action\/doSearch?ContribAuthorStored=Golden%2C+Heather+E\" data-id=\"a1\" data-db-target-for=\"a1\" aria-controls=\"a1\" aria-haspopup=\"true\">Heather E.

Measuring the performance of the GI is significantly more complex because it aspires to provide more for urban spaces than conventional grey infrastructure. Ecological and societal benefits are more difficult to quantify than the conveyance capacity of a pipe. The ecosystem services supported by GI operate on a variety of scales and can serve multiple functions: water quality improvements, enhanced water security, pollination, enhanced food security, health and wellness improvements, enhanced livability, and urban biodiversity.

Ecological and societal benefits are more difficult to quantify than the conveyance capacity of a pipe. The ecosystem services supported by GI operate on a variety of scales and can serve multiple functions: water quality improvements, enhanced water security, pollination, enhanced food security, health and wellness improvements, enhanced livability, and urban biodiversity. This diverse array of benefits provides GI with a compelling cost-benefit analysis.<\/p>\n<h3>Scales of GI<\/h3>\n<p>&nbsp;<\/p>\n<h6><a href=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-120 size-full\" src=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM.png\" alt=\"\" width=\"521\" height=\"662\" srcset=\"https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM.png 521w, https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM-236x300.png 236w, https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM-65x83.png 65w, https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM-225x286.png 225w, https:\/\/pressbooks.bccampus.ca\/greeninfrastructure\/wp-content\/uploads\/sites\/1424\/2021\/06\/Screen-Shot-2021-01-20-at-2.58.23-PM-350x445.png 350w\" sizes=\"auto, (max-width: 521px) 100vw, 521px\" \/><\/a><\/h6>\n<h6>Source: Page 8 of <a href=\"http:\/\/www.metrovancouver.org\/services\/regional-planning\/PlanningPublications\/ConnectintheDots.pdf\" target=\"_blank\" rel=\"noopener\">http:\/\/www.metrovancouver.org\/services\/regional-planning\/PlanningPublications\/ConnectintheDots.pdf<\/a><\/h6>\n<p>As you will explore in upcoming modules, urban drainage and the integration of grey with blue-green cities through the implementation of GI is not only providing co-benefits such as supporting the management of stormwater, reducing the heat island effect, improving water quality, enhancing water security, and providing benefits to health and wellness, it is also contributing to climate change resilience.<\/p>\n<div class=\"textbox textbox--exercises\">\n<header class=\"textbox__header\">\n<p class=\"textbox__title\">Learning Activities<\/p>\n<\/header>\n<div class=\"textbox__content\">\n<ul>\n<li>Read the four short articles and view the video for this module.<\/li>\n<\/ul>\n<h4>Discussion Question<\/h4>\n<ul>\n<li>Introduce yourself and share your learning goals for the course.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<div class=\"textbox textbox--examples\">\n<header class=\"textbox__header\">\n<p class=\"textbox__title\">Readings &amp; Resources<\/p>\n<\/header>\n<div class=\"textbox__content\">\n<h4>Readings<\/h4>\n<ul>\n<li><a class=\"external\" href=\"https:\/\/www.epa.gov\/green-infrastructure\/what-green-infrastructure\" target=\"_blank\" rel=\"noreferrer noopener\">EPA Green Infrastructure Guide<span class=\"screenreader-only\">\u00a0<\/span><\/a><\/li>\n<li><a class=\"external\" href=\"https:\/\/doi.org\/10.1080\/1573062x.2014.916314\" target=\"_blank\" rel=\"noreferrer noopener\">Fletcher, T.
