A Tcs unit near Bishop's Beach in Homer just after the fall flooding of 2003 (yet unmapped). |

The Tcs map component represents the beach along bluffs and other features common along the Cook Inlet and Kachemak Bay shoreline. At least the highest spring tides, sometimes accompanied by moderate wave action, inundate Tcs. Vegetation is absent and the loose substrate is often composed of cobbles. Bluff erosion frequently contributes boulders and chunks of coal to the beach.
This unit often will not meet jurisdictional criteria outlined in the 1987 Army Corps of Engineers wetland delineation manual as a wetland, depending on the frequency of flooding.
