3. Erosion Problem
Severe streambank erosion occurring near 2 roadways, County Rd. # 172 (Stottle Road) and State Rt. 33A, in the Town of Chili located in Monroe County N.Y. on Black Creek, a tributary of Lake Ontario.
These sites are causing excessive sedimentation and pose a potential threat to the existence of sections of these roadways.

4. Great Lakes Basin PR OJ EC T LO CA TI ON Chili Ave Site
Stottle Rd Site

5. Erosion Rates
Site located on Stottle Road loses approximately 6 inches of streambank per year , and Black Creek is within 8 feet of the roads edge.
Site located on State Rt. 33A, loses approximately 1 foot of streambank per year.
Both sites had undercut banks, and are experiencing slippage and sloughing.

6. Goals of Project
Stabilize two sections of streambank in Black Creek that are experiencing severe bank erosion by installing a BMP, thereby reducing 70 tons of soil per year from entering Black Creek.
Educate 25 municipalities on streambank stabilization BMPs, and therefore; would have a better understanding of problems associated with bank erosion and BMPs to correct them.

11. Stottle Road Construction
200 linear feet of streambank was stabilized with large rip rap along the west bank of Black Creek.
A hydraulic tracked excavator and dump truck were used to place the rock for approximately 10’.
Purple-osier willow (Salix purpurea) was planted as live stakes and joint plantings at a density of 2-4 stems per 10yd2 .

12. Stottle Road Construction
Topsoil was added near the top of the bank, and the project area was hydroseeded with a mix of 40% Fine Perennial Ryegrass, 40% Creeping Red Fescue, 10% Kentucky Blue, and 10% Annual Rye.
A fertilizer was used with the seed and the site was mulched with straw at a rate of 2 tons per acre.

August 18, October 2, 2008

30. Chili Avenue Construction
250 linear feet of streambank was stabilized with medium stone rip rap along the north bank of Black Creek.
The north bank was re-sloped and graded using a hydraulic tracked excavator to a 2:1 slope.
The north bank was lined with a geotextile fabric.
Rip rap was placed on the fabric to a maximum thickness of 18 inches. Rip rap was keyed 2’ x 3’ into the bed of Black Creek to stabilize the toe of the bank.

31. Chili Avenue Construction
Native vegetation was planted as live stakes and joint plantings at a density of 2-4 stems per 10yd2. Native species included silky dogwood (Cornus amomum), purple-osier willow (Salix purpurea), black willow (Salix nigra), and eastern cottonwood (Populus deltoides).
Topsoil was added near the top of the bank, and the project area was hydroseeded with a mix of 40% Fine Perennial Ryegrass, 40% Creeping Red Fescue, 10% Kentucky Blue, and 10% Annual Rye.
A fertilizer was used with the seed and the site was mulched with straw at a rate of 2 tons per acre.
