South Bend Redevelopment Commission <br />Regular Meeting –April 9, 2010 <br /> <br />storm sewer overflow. <br /> <br />Mr. Downes asked if the question of pond <br />capacity came up at the time the city widened <br />the intersection. <br /> <br />Mr. Schalliol responded that we knew when <br />we were doing Erskine Village six years ago <br />that we needed to address the drainage on the <br />west side of Miami. That was about the time <br />we looked to move the pond to the golf <br />course. And then we thought about selling <br />the golf course as part of a retention project. <br />Then, we went back to the concept of putting <br />retention ponds into the golf course. The <br />problem with the retention needs that we <br />have are that we need holes. We don’t need <br />ponds with fountains, because there’s <br />nowhere to put the water. Ponds with <br />fountains require a more or less constant <br />level of water. As we worked with the golf <br />course to design a system that would allow <br />for water to look nice, but would also allow <br />for the overflow. In 2009 there were eleven <br />days of course closure at Erskine Golf <br />Course due to flooding. For years before we <br />put in the sensor, every time it would rain it <br />would flood out the Twyckenham Hills <br />neighborhood. Anybody who didn’t have <br />proper systems would get water in their <br />basement. <br /> <br />This has been a long, ongoing problem. The <br />ponds were developed years ago, before we <br />had the 100-yr storm water requirements. <br />They are very under-sized. Maintenance has <br />been an issue. As we’ve explored the <br />condition of these ponds, we’ve found some <br />places where there is 14 ft of silt built up. <br />Even clearing the existing ponds out would <br />improve the situation. The existing ponds <br />are not large enough to re-slope to get the <br /> 33 <br /> <br />
