2019-06Ithaca Reservoir Stream Restoration and Sediment Reduction Project (Six Mile Creek Vineyard)Deveop a project design which will reduce velocity, sediment and pollution and possibly armor/stabilize outlet to reduce maintance need and reduce risk of vineyard loss of land, and reduce sediment and nutrient loading in creek which flows to City of Ithaca water supply area.Town of Ithaca, Tompkins County SWCD, Six Mile Creek Vineyard, Seneca Watershed IO, Barton & Loguidice33000Non-Agricultural Nonpoint Source Planning and MS4 Mapping GrantSpring 2023 Completion DeadlinePjt_2019-06.pdf Pjt_2019-06_map.pdf
2019-23County Road 150 Streambank / Roadbank Stabilization ProjectThis project will address approximately 300' of streambank stabilization and erosive undercutting of County Rd. 150, a main artery from the shores of Cayuga Lake to the Village of Interlaken and the state routes nearby. Without stabilization, County Rd. Since the flooding in 2018, sedimentation and streambank erosion have increased. The NRCS EWP project will also include work sites on Knight Street and Mechanic Street in the Village of Interlaken which will reduce flood risk to property and reduce stream erosion. Additional project work will include stream and roadbank stabilization.Seneca County SWCD, USDA NRCS, Village of Interlaken, Private Landowners$350,000 - $600,000 (Estimate)USDA NRCS Emergency Watershed Protection ProgramConstruction in 2023EWP Fact Sheet: Pjt_2019-23_InterlakenPjt.pdf
2019-24County Road 150 Streambank Erosion & Retention Basin ProjectAs a result of the August 2018 flood, the existing railbed and culverts could not withstand the massive amounts of stormwater, overtopping the railbed. This resulted in substantial downstream erosion and subsequent sediments washing downstream. The existing culverts are not functional and future storm events will impact downstream infrastructure and will create more erosion transporting more sediment and debris to Cayuga Lake.NYSEG, Seneca County SWCD$350,000 - $600,000 (Estimate)NYSEG2022Pjt_2019-24.pdf
