detention pond at 244th
October 2004 - Rainwater runoff from SR 18 will drain into this detention pond under construction at the 244th interchange site.  The pond will remove pollutants and sediment before the water is released.  The green color on the pond slopes is the result of grass seeding to prevent erosion.
