yesterday's blog the US is losing wetland areas rapidly. The US is losing 1000 acres of wetlands a day. The efforts of developers to build housing and a golf course near the Blackwater Wildlife Refuge on the Eastern Shore were highlighted a few years ago in many articles in the Baltimore Sun. We are fortunate in this area that the development of Columbia took into consideration the preservation of wetlands. As I wrote in my May 2nd blog from one of the planners of Columbia,
" The staff had done a good deal of geographic work. The best stands of forest - and there are some magnificent individual trees as well as forests - had been plotted, and the areas providing views to the community had been exploited or preserved for common use and had been mapped (about 40% of Columbia is green space). The streams had been studied as to their usual and unusual flow patterns so that areas safe from flooding were known. The function of the streams in providing barriers within the area had been looked into and their possible function in supplying artificial lakes for recreation (Lake Kittaquandi, Wilde Lake and Elkhorn). Their steep banks in some areas precluded building economically on them and made them obvious candidates for relatively uncultivated, natural areas not to "be lightly interfered with."
Many of our wetlands are traversed by elevated bridges to less the environmental impact on the areas.
