The northern border of 51ÁÔÆæ&#8217;s campus is a low-laying area prone to flooding during heavy rain events, and the combined sewer can become over stressed during heavy rains. 51ÁÔÆæ, with its available landscape and rooftops, helps manage stormwater runoff through a variety of green infrastructure solutions and resilient landscapes. Through research and application, UW-Milwaukee diverts approximately 16.5 million of gallons of stormwater every year and strives to lead by example in the region. <\/p>\n\n\n\n<p>The <a href=\"https:\/\/storymaps.arcgis.com\/stories\/d4c087635be5437b82325e7e6731f7b3\">51ÁÔÆæ Sustainability and Green Infrastructure Self Guided Tour StoryMap<\/a> provides an in-depth summary of many of green infrastructure features across the campus.<\/p>\n\n\n\n<div class=\"uwm-p-tabs\" data-tabs-prefix-class=\"uwm-p-tabs\"><ul class=\"uwm-p-tablist\" data-hx=\"h2\"><li class=\"uwm-p-tablist--item\"><a href=\"#tab-y2k7-green-roofs\" class=\"uwm-p-tablist--link\">Green Roofs<\/a><\/li><li class=\"uwm-p-tablist--item\"><a href=\"#tab-y2k7-rain-gardens-and-cisterns\" class=\"uwm-p-tablist--link\">Rain Gardens and Cisterns<\/a><\/li><li class=\"uwm-p-tablist--item\"><a href=\"#tab-y2k7-bioswales\" class=\"uwm-p-tablist--link\">Bioswales<\/a><\/li><\/ul><div class=\"uwm-p-tabcontent\">\n<div id=\"tab-y2k7-green-roofs\" class=\"uwm-p-tabcontent--pane\">\n<p class=\"size-p-lg\">The implementation of green roofs at 51ÁÔÆæ is a prime example of addressing sustainable objectives in an urban environment. <\/p>\n\n\n\n<p>Green roofs address the problem that cities have with the&nbsp;<em>Urban Heat Island Effect<\/em>&nbsp;and increased rapid stormwater runoff from impervious surfaces.&nbsp; Green roofs also provide the benefits of reduced costs on heating and cooling, decreased long-term maintenance and longer life span than a conventional roof, improved air quality, and increased urban habitat for wildlife.<\/p>\n\n\n\n<p>A green roof system is an extension of the existing roof which involves a high quality water proofing and root repellant system, a drainage system, filter cloth, a lightweight growing medium and plants.<\/p>\n\n\n\n<p>Since the early 1990\u2019s, 51ÁÔÆæ has installed green roofs.&nbsp; From parking garage roofs at ground level, to student demonstration projects, to full scale green roofs, the 51ÁÔÆæ campus has established many green roofs, and looks to execute more based on future roof repair and accessible locations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-green-roofs-at-uwm\">Green Roofs at 51ÁÔÆæ<\/h2>\n\n\n\n<div class=\"uwm-p-accordion uwm-p-accordion--icon-left-circle\" data-accordion-prefix-classes=\"uwm\" data-accordion-cool-selectors=\"1\"><button class=\"uwm-p-accordion--toggle-button size-p-md\">Expand All<\/button>\n<div class=\"uwm-p-accordion--header\">Golda Meir Library<\/div><div class=\"uwm-p-accordion--panel\"><div class=\"uwm-p-accordion--panel-inner uwm-u-clear\">\n<p><strong>Year Built:&nbsp;<\/strong>2011<strong><br>Footprint:&nbsp;<\/strong>50,000 Square Feet<\/p>\n\n\n\n<p>The Golda Meir Library green roof features two separate roof sections and a 30-kilowatt system of solar panels sponsored by WE Energies, with the support of Focus on Energy grants. This is the largest green roof at 51ÁÔÆæ. The green roof project was made possible through a partnership with the Metropolitan Milwaukee Sewerage District (MMSD). Student research projects at the Golda Meir Library green roof have showed the co-benefits of pairing solar panels and green roofs together to improve energy efficiencies of the solar array. Students have also studied the migration patterns of pollinators in the urban environment and the positive benefits greens roofs can provide beyond water quality.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"uwm-p-accordion--header\">Cambridge Commons<\/div><div class=\"uwm-p-accordion--panel\"><div class=\"uwm-p-accordion--panel-inner uwm-u-clear\">\n<p><strong>Year Built:&nbsp;<\/strong>2010<strong><br>Footprint:&nbsp;<\/strong>13,000 Square Feet<\/p>\n\n\n\n<p>Cambridge Commons, 51ÁÔÆæ\u2019s newest residence hall addition, features two green roofs which help to reduce heating and cooling costs and absorb pollutants from stormwater runoff.
