Channel work on Ransom and Tonawanda creeks and a 2 1/2 -mile-long diversion channel across northern Clarence are the basic elements of a Tonawanda Creek flood-control project favored by Amherst, the town's drainage chief disclosed Thursday.
"Plan 11" -- one of five alternatives being considered by the Army Corps of Engineers -- "does the job and the cost is not prohibitive. What a godsend it would be," Amherst Councilman and Deputy Supervisor Harold J. Collier said.
Meanwhile, Collier's counterpart in neighboring Clarence, Councilman Roland L. Boller, Wednesday said officials there soon will decide between Plan 11 and Plan 3.
The Corps of Engineers is expected to schedule a meeting this summer on the various plans with officials from communities periodically troubled by the flooding of Tonawanda Creek and its tributaries.
Boller urged landowners in the Tonawanda Creek flood plain in Clarence to contact him if they would like a meeting with Corps of Engineers representatives.
The big difference between Plan 11 and Plan 3, according to the Corps of Engineers, is that nine "oxbow cuts" off the main channel and major Tonawanda Creek channelization work in Plan 3 is replaced by the Clarence diversion channel in Plan 11.
Plan 3 also is "much more expensive," Collier said.
According to the Corps of Engineers' Plan 11, the Clarence diversion channel would have a 115-foot-wide bottom and an average depth of 12 feet. Some fill excavated from the channel would be used to fill low areas nearby.
The channel would begin on Tonawanda Creek near Westphalinger and Tonawanda Creek roads, proceed east past Westphalinger midway between Tonawanda Creek and Sesh roads, then southeast toward Sesh, which it would parallel to Goodrich Road.
A system of collector ditches would be built l plan
east of Goodrich to funnel floodwater into the diversion channel. A new bridge to span the diversion channel would be needed on Tonawanda Creek Road just east of Westphalinger.
"Clearing and snagging" work in Tonawanda Creek between the Erie Barge Canal and the diversion channel also would be needed.
Meanwhile, Plan 11 would result in this work along Ransom Creek in Amherst:
A 40-foot-wide channel bottom for 1.67 miles between the Tonawanda Creek Road bridge and the Hopkins Road bridge.
Selective clearing and snagging work in the creek channel and for 50 feet along each bank for almost nine-tenths of a mile between the Hopkins Road and Millersport Highway bridges.
Excavation of a 200-foot-wide floodway along the right bank for about seven-tenths of a mile between the Millersport Highway bridge and near the intersection of Smith and Dann roads. The floodway would store water during high flows.
Selective grading or earthen levees along the right bank beginning behind homes on White Cedar Drive and Smith Road and continuing to where Ransom Creek flows under Glen Oaks Drive.
On the left bank, just downstream from Glen Oaks Drive, grading or levees perpendicular to the creek to protect homes from flooding. From the Glen Oaks Drive bridge upstream to the Dodge Road bridge, grading or levees along both banks.
