Hydric Soils Hydric or wet soils are characterized by poor drainage and a water table at or near the surface of the ground at least during a portion of the year. Hydric soils are considered to pose serious development constraints and frequently support wetlands. In Louisville, a large area of hydric soils occurs in the Slack-water Flats region on either side of Interstate 65. Most of this area has been ditched to drain the land, thereby allowing extensive residential, commercial and industrial development. C2. Hydrology Several of Louisville’s streams - Beargrass Creek, Goose Creek, Harrods Creek and Mill Creek- flow directly into the Ohio River. Floyds Fork and its two smaller watersheds (Cedar Creek and Pennsylvania Run) drain south to the Salt River in Bullitt County. Pond Creek also drains into the Salt River just before the Salt flows into the Ohio River at Louisville’s southeastern corner. River and Stream Corridors The Ohio River, Floyds Fork, Beargrass Creek, Pond Creek, Mill Creek, Harrods Creek and Goose Creek and associated tributary stream corridors are of major importance to Louisville’s environmental, recreational, and visual quality. Important resources occurring along these corridors include significant undeveloped tracts of land, steep slopes, natural communities and wildlife habitat areas such as forest and wetlands, historic sites, and recreational and visual amenities. However, the environmental health of many of 2012, LOJIC Louisville’s river and stream corridors has been impacted by pollution, sedimentation, and channelization associated with urban development. Poor water quality is a significant constraint to the recreational usage of many of Louisville’s streams. One of the major rivers in the United States, the Ohio River forms the northwest boundary of Louisville with Harrison, Floyd, and Clark Counties in Indiana. The Ohio River corridor is a major scenic and recreational resource for the region; provides natural habitat for a variety of wildlife including many species listed as rare, threatened and endangered; and contains significant historic resources including the Olmsted-designed Shawnee Park and historic residential homes and estates such as Riverside, the Farnsley-Moremen Landing. The part of Louisville that drains directly into the Ohio River Watershed (excluding Beargrass, Goose and Harrods Creeks) is approximately 40 square miles. This area was once drained by Paddy’s Run which is now entirely underground and part of the public sewer system. Parks and Recreation System Master Plan | III. CONTEXT AND COMMUNITY INVENTORY 35
