+ Lake Plain
The Lake Plain forms a wedge shaped area that extends from the
bluffs along the lakeshore to the base of the Escarpment that marks the transition to
the Allegheny Plateau to the south and east. This area was once the lake bottom of
higher level lakes that proceeded the present day Lake Erie. Consequently much of the
surface consists of lake bottom deposits.
Beach Ridges. The surface, except for the southernmost mile
or so, is so level that drainage is poor. Another exception are a series of ridges
that traverse the Lake Plain and which were once beaches of the ancient higher level
lakes. These sandy and gravely beach ridges drained better than most of the surrounding
land and offered better views of the neighboring countryside. These advantages made them
natural travel corridors for the Native Americans that lived and hunted in the area.
The white settlers used these native trails as the basis for
locating many of the main streets that traverse the Lake Plain. Euclid, Detroit and
Lorain Avenues all follow routes of ancient beach ridges. Much of the
City of Cleveland, including Downtown,
is located on the Lake Plain.
Native Vegetation. The Lake Plain was originally covered
by a mixed forest whose character varied with the topography, drainage and character
of soil. On the better drained land and sandy beaches chestnut, black oak, white oak,
white ash, beech and tulip were in the majority. In wetter places American elm, black
ash, and silver maple or pin oak predominated. Some black walnut, butternut and sycamore
could also be found in these wetter areas.
Drainage Channels. The area is noticeable for a lack of
natural drainage channels and streams. Some streams did cut courses through the Lake
Plain before emptying into the Cuyahoga River and
Lake Erie. Many of these original valleys have been filled and the water courses
incorporated into the sewer system. Much of the area was developed early in the history
of Cleveland and is served by combined sanitary and storm sewers.
The high cost of remediating combined sewers could be offset by
a program of retrofitting properties to increase infiltration and provide increased
amenities in the form of small parks and other public areas. Large paved areas, such
as surface parking, could be retrofitted to infiltrate or store storm water beneath
them. Green roofs on buildings are another alternative for reducing storm water
runoff and reducing the effects of the urban heat island.
