A swamp grass mix will be used to reseed the rip rap area. Another culvert was placed next to the other 40' culvert taking care not to disturb the original stream and placing it 6" higher so as to receive only storm flow. This will reduce the stream length disturbed to about 130'. Only one page on the original application has changed so we are enclosing that page.
