Robison, the lead engineer for Tulsa\u2019s stormwater program, approaches the home and knocks on the front door. His mission today: Meet the owners and convince them to sell their home to the city.<\/p><p>The house has changed hands a bunch of times in recent years and it has flooded \u2014 repeatedly. It\u2019s one of more than 80 houses Robison and the city are currently trying to buy. Over the last three decades, the stormwater program has helped Tulsa clear <a href=\"http:\/\/nrcsolutions.org\/tulsa-oklahoma\/\">nearly a thousand<\/a> buildings from flood-prone areas.<\/p><p>\u201cTypically, after people are flooded two or three times, they&#8217;re ready to sell out,\u201d Robison says.<\/p>\n<div id=\"attachment_28786\"  class=\"wp-caption module image right\" style=\"max-width: 620px;\"><a class=\"fancybox\" title=\"Neighborhoods and mobile home parks in Tulsa after the Arkansas River flooded in October 1986.\" href=\"https:\/\/stateimpact.npr.org\/oklahoma\/files\/2017\/11\/TCCLAW-ah0256.jpg\" rel=\"\"><img decoding=\"async\" loading=\"lazy\" class=\"size-large wp-image-28786\" alt=\"Neighborhoods and mobile home parks in Tulsa after the Arkansas River flooded in October 1986.\" src=\"https:\/\/stateimpact.npr.org\/oklahoma\/files\/2017\/11\/TCCLAW-ah0256-620x489.jpg\" width=\"620\" height=\"489\" \/><\/a><\/p>\n<p class=\"wp-media-credit\">Austin Hellwig Collection \/ Tulsa City-County Library<\/p>\n<p class=\"wp-caption-text\">Neighborhoods and mobile home parks in Tulsa after the Arkansas River flooded in October 1986.<\/p>\n<\/div>\n<h3>Floods and Frisbees<\/h3><p>Home buyouts are one part of <a href=\"https:\/\/www.cityoftulsa.org\/government\/departments\/engineering-services\/flood-control\/\">a municipal hazard mitigation plan<\/a> designed to save lives and save millions of dollars in property losses caused by floods that have historically devastated the city. It\u2019s a comprehensive and aggressive plan other cities might soon copy.<\/p><p>\u201cEverything happens at the local level, and if you don&#8217;t have the local people on board you haven&#8217;t got a program,\u201d says Ron Flanagan, a consultant and principal planner at Flanagan & Associates who had a lead role in writing the city\u2019s program. \u201cThe federal government can&#8217;t enforce everything and they have minimum standards.<\/p><p>Tulsa is surprisingly vulnerable to flooding. The southern tip of the city is sliced by the Arkansas River, which swells from local rains and precipitation that flows in from northern and western Oklahoma. Other Tulsa neighborhoods are scattered among a spiderweb of 36 creeks.<\/p><p>Buying out homeowners isn\u2019t the city\u2019s only strategy for managing flood risks. The city started accounting for urban growth in its flood plain calculations and built a network of drainage systems. Flood managers also created green spaces that serve as flood basins. Day-to-day, many of these spaces are used as parks and soccer fields or disguised as neighborhood ponds.<\/p><p>\u201cYou can see there&#8217;s a frisbee golf course here, walking trails and just a nice open area,\u201d Robison says as he surveys Carol\u2019s Pond, a grassy, park-like basin named for the late flood activist Carol Sue Williams.<\/p>\n<h3>Great Drainage War<\/h3><p>In the 1970s and \u201980s, Tulsa was hit by a string of damaging floods, and city leaders started working on a plan for rising waters to break an expensive and hazardous disaster-then-rebuild cycle. This sparked a period of fierce opposition and politicking dubbed the \u201cGreat Drainage War,\u201d as activists and city officials squared off with property developers and builders over proposed rules and restrictions.<\/p><p>In 1984, a <a href=\"https:\/\/www.weather.gov\/tsa\/1984may26_tulsamemorialdayflood\">stalled cold front<\/a> dumped more than a foot of rain across the city. Fourteen people died and hundreds were injured; more than 5,000 homes and buildings were destroyed or damaged. Flanagan and Robison say the Memorial Day flood galvanized the public and cleared a path for city officials to sign off on more aggressive action.<\/p>\n<div id=\"attachment_28789\"  class=\"wp-caption module image right\" style=\"max-width: 620px;\"><a class=\"fancybox\" title=\"Tulsa's flood-control plan includes multi-use drainage basins, like the athletic field at Will Rogers High School.

The field has a football field, track and bleachers and doubles as a detention pond for overflowing stormwater.<\/p>\n<\/div><p>Flood-minded construction and property ordinances and zoning requirements add fees and increase costs for <a href=\"https:\/\/qz.com\/1064364\/hurricane-harvey-houstons-flooding-made-worse-by-unchecked-urban-development-and-wetland-destruction\/\">builders and developers<\/a>, which often resist flood planning. To help pay for its program, the city added a stormwater management fee to utility bills, which was \u2014 and remains \u2014 unpopular with many residents.<\/p><p>Flanagan consulted flood planners in Houston in the past, and says <a href=\"https:\/\/www.propublica.org\/series\/hell-and-high-water\">the Texas gulf city\u2019s risks<\/a> are unique. But, he says, any local government drafting flood-control rules will likely face the same challenges posed by developers and builders.<\/p><p>\u201cElected officials are very sensitive to the development community&#8217;s wants and desires and needs,\u201d he says.<\/p><p>Flanagan says flood-control plans come with unavoidable costs. But he and other flood planners and stormwater managers say the most cost-effective solutions come in the design phase of construction or property development.<\/p><p>\u201cThe sooner you address these things the cheaper it is,\u201d he says. \u201cAs you keep putting these things off during the development process, it gets exponentially more expensive.\u201d<\/p><p>Tulsa\u2019s program goes well beyond standards outlined by the Federal Emergency Management Agency, which improves the city\u2019s <a href=\"https:\/\/www.fema.gov\/national-flood-insurance-program-community-rating-system\">Community Rating Score<\/a> and reduces flood insurance rates for residents. Robison says this has saved residents about $400,000 on roughly 1,500 policies.<\/p>\n<h3>Potholes and Flood Plans<\/h3><p>National groups say Tulsa is a model for how cities can plan for flooding as urban areas grow and climate patterns change. The State Department has even led delegates from countries like Russia and Azerbaijan to Tulsa to see the plan in action.<\/p><p>The strategy has worked: Today, Tulsa\u2019s flooding problems are much smaller. But, Flanagan and Robison both worry the success could make it hard to expand and adapt the plan down the road. They say the longer the city goes without a catastrophic flood, the easier it gets to forget what the planning is for and justify to the public and city officials why the program is worth its share of limited municipal money and resources.<\/p><p>\u201cWe\u2019re competing with potholes,\u201d Robison says. \u201cEverybody in town has to deal with potholes.
