Scientists defend storm-water controls

Scientists and others engaged in protecting Maryland’s rivers and streams are rising to the defense of the state’s storm-water management laws in the wake of Harford County Executive David Craig’s call for their repeal. Craig, a leading Republican candidate for governor in next year’s election, said earlier this week that he would push for repeal of at least three state environmental laws, including one requiring property owners in Baltimore City and the state’s nine largest counties to pay a fee for reducing storm-water runoff in their communities. The fee, which Craig and other critics have dubbed a “rain tax,” is generally assessed based on the amount of pavement and rooftop that property owners have. Craig contends the fees are inconsistently applied and so steep in places like Baltimore that they’ll drive businesses out. But in calling for the fee’s repeal, Craig took aim at the scientific basis for focusing on such “impervious surface.” “The impervious surface really doesn’t matter,” Craig said. “The rain is going to get through somewhere, somehow.” Craig also called for repeal of a 2007 law tightening requirements for new development to limit storm-water runoff, and of a 1984 law limiting development near the shore of the Chesapeake Bay and its tributaries. Scientists take issue with Craig over his statement questioning the science behind the storm-water fees. “Mr. Craig’s comment flies in the face of all available science on the issue, and more importantly, in the face of common sense,” said Andrew J. Elmore, an associate professor at the University of Maryland’s Appalachian Environmental Laboratory in Frostburg. Hye Yeong Kwon, executive director of the Center for Watershed Protection in Ellicott City, said the connection between impervious surface and stream vitality has been established for years now. Rainfall runs off pavement and roofs when in an undeveloped setting it would soak into the ground, explained Kwon. Her nonprofit center works with local governments and others to curb the effects of storm water.
