The Coalition of Little Rock Neighborhoods is urging supporters of clean water to attend a Quorum Court committee meeting at 6 p.m. Tuesday. Up for discussion: a six-month moratorium on construction in the Lake Maumelle watershed. The Quorum Court is way overdue in instituting land-use rules that would give the county more jurisdiction in the undeveloped part of the county. Pressure is great because developers are already trenching hillsides overlooking the north shore of the lake and notorious developer Jay DeHaven is poised to create problems on the western end of the watershed. Supporters are not expected to speak, merely to give support in numbers to what has been a sometimes lonely fight by a couple of strong members of the Quorum Court.
