Tonawanda Creek Collapse - Lockport
Reynolds: House Approves $800,000 for Town of Lockport Funding will be used to stabilize Tonawanda Creek Road North U.S. Representative Thomas M. Reynolds, R- Clarence, announced today that the U.S. House of Representatives has approved his request for $800,000 for the Town of Lockport, as part of a 2006 Energy and Water spending bill. The funding will be used to stabilize Tonawanda Creek Road North.
"This stretch of Tonawanda Creek Road, just east of Minnick Road, is being threatened by bank erosion, with the road already showing some signs of sinking," Reynolds said. "Obviously, this is a concern for local residents

The applicant proposes a stream bank protection project located on Tonawanda Creek at Tonawanda Creek Road North near Minnick Road in the Town of Lockport. The project consists of the removal and subsequent reconstruction of 120 foot of the road, installation of a 4 foot diameter drainage culvert pipe and construction of a 230 foot long steel sheet pile retaining wall, with associated granular fill of 400 tons of crushed stone and a rock riprap revetment toe consisting of 800 tons of 18-inch stone to protect the streambank from erosion.
The cause of stream bank collapse is known:
Any change in the watershed feeding the stream, in the floodplain, or in the stream itself can upset this delicate balance. The three major causes for increased streambank erosion are:

Land Use Change: When we build houses, sidewalks, and roads over soil, we reduce the amount of water that can enter the ground. Consequently, water runs off faster, at higher temperatures, and with more erosive energy into streams. Streams become "flashy," erosive, and flood-prone. When we remove trees and vegetation next to a stream and allow livestock to trample banks, this exposes the soil. As a result, streambanks may erode more rapidly and slump into the water. Dams: When we build dams, the dams trap sediment and change the amount of sediment and energy in the stream below. Streams must move sediment, so the stream looks for a new source, the banks! Straightening Streams: When we straighten a winding stream, we remove the meanders that reduce the erosive power of water. In the past, streams were channeled to move water quickly through flood-prone or erosive areas. But instead of solving a problem, it only moved the problem downstream with even greater force.

Ransom Creek Watershed- “environmental feature of countywide significance”
The Amherst floodplain maps have not been updated since 1992. Comprehensive data and stormwater management plans that includes all municipalities who contribute water to the watershed problem are lacking. “Erie County has designated the Ellicott and Ransom Creek watersheds as “environmental features of county wide significance. Watershed management planning for these creeks in cooperation with other municipalities and possibly Erie County would be an effective way to address watershed-wide water quality and stormwater management issues”
