Stream Projects

Stream Buffer 2016

Stream buffers act as a barrier, filtering pollutants and sediment, stabilize streambanks and reduce erosion. The District received funding from the county under the Finger Lakes-Lake Ontario Watershed Protection Alliance (FL-LOWPA) to implement a riparian buffer project in the Town of Chili along a stream that drains into Black Creek. The goal of the project was to reduce nutrients and sediment entering the stream, as well as to prevent mowing directly up to the edge of the stream. Approximately 4,560 square feet on both sides of the stream were planted with 118 native tree and shrub species consisting of Pin Oak, Red Bud, Swamp White Oak, Sycamore, Winterberry, Redosier Dogwood, Nannyberry and Silverberry. The buffer will save 3,075 tons of sediment and 2,706 tons of phosphorus from entering the stream over the next 15 years. Six educational signs were placed along the stream buffer that had an educational message to teach visitors about the importance of buffers by describing their functions and how they protect water quality.


Buckland Creek Restoration Project 2011

The purpose of the project was to restore natural stream morphology and riparian corridor to a 350 foot section of Buckland Creek, which has been channelized due to development prior to stormwater regulations. The creek was restored to more natural stream characteristics and dynamics. This project's additional purpose is to filter the multitude of pollutants of concern from the otherwise untreated stormwater. Pollutants of concern for this waterbody include, organics such as PCBs, pesticides, pathogens, silt/sediment, oil and grease, and nutrients such as nitrogen and phosphorous.

The project consisted of a section of Buckland Creek located in the Town of Brighton, Monroe County. Buckland Creek at this location was straightened and channelized due to development in the 1950s. The stream was incised and no riparian corridor/buffer was present due to mowing up to the top of bank. The purpose of the project was to restore a natural stream morphology to this 350 foot section of Buckland Creek. The stream was restructured to mimic more natural stream conditions and reduce erosion around two bridges. Once the stream was regraded to mimic more natural flow conditions, the side slopes of the channel were also regraded, seeded and stabilized with jute mesh, and planted with over 1000 trees, shrubs, and riparian corridor plantings. The buffer extended on both banks for approximately 25 feet.

Black Creek Stabilization Project 2008

The District completed 450 linear feet of streambank stabilization on Black Creek at two sites in the Town of Chili. The project commenced in August, 2008 and was completed 5 weeks later on September 24, 2008. MCSWCD technicians worked with the Town of Chili Highway Department and Department of Public Works to construct the stabilization measures. The stabilization technique used rock rip-rap with a mix of native species planted between the rocks, to allow for a vegetative cover to improve cooling effects for aquatic life, filter pollutants from runoff events, minimize sediment loss, and beautify the surroundings. The project was funded by the Great Lakes Commission through a grant that the MCSWCD received in 2006.

Black Creek Geomorphic Assessment 2010

With grant funds received in 2009 by the Great Lakes Basin Program for Soil Erosion and Sediment Control for the Genesee River Watershed Soil Erosion Control Project, the District planned to stabilize 125 feet of streambank on Black Creek in the Town of Chili in order to reduce approximately 27 tons of soil loss per year. Sediment is listed as a known pollutant source by the NYS Department of Environmental Conservation that had impaired aquatic life and stressed Black Creek for aesthetics and recreation. As part of the grant funds received, field data was collected and analyzed to understand the variables which shape the dimension, pattern, and profile of the creek. This process is known as Geomorphic Assessment. Two major watershed areas totaling 11,000 acres were analyzed within the project area and evaluated by cover type, land use, and by soil type using aerial photography. Field data was collected at the site such as conducting a pebble count to verify streambed features, using a total station to survey the streambank and bed along several cross-sections of the project area to determine the creek width to depth ratio, using a total station to survey a longitudenal profile to establish the gradient of the creek, and conducting a bank erosion hazard index (BEHI) survey. BEHI is used to quantify the potential for the bank to further erode by looking at the bank height ratio, bank angle, vegetation root depth and density, bank protection present, and bank materials. All data collected was analyzed to evaluate the existing channel conditions to provide a basis for choosing a best management practice to implement on the site.

Black Creek Stabilization Project 2011

The District completed 125 linear feet of streambank stabilization on Black Creek located east of Old Scottsville-Chili Road, in the Town of Chili. The project commenced on September 12, 2011 and was completed on September 28, 2011. MCSWCD technicians worked with the Town of Chili Highway Department and Department of Public Works to construct the stabilization measures. Severe erosion of the southern bank of Black Creek was occuring at this site, leading to soil loss, steep slopes, and compromising the integrity of the roadway and guardrail above.
Stabilization of the streambank involved the installation of stacked rock rip-rap, deflection stones, and re-sloping of the remaining slope. Live cuttings were planted in the crevices between the stacked rip-rap to provide further soil stabilization, beneficial cooling effects, pollutant filtering, and aesthetic enhancement. Compacted fill and topsoil was brought in to re-slope the banks above the stacked rip-rap. Flexterra (high performance-flexible growth medium) was used to permanently stabilize the newly graded streambank. Upon completion, the stacked rock rip-rap will act as a protective barrier, deflecting the Black Creek currents away from the streambank, preventing further erosion. The project was funded by the Great Lakes Commission through a grant that the MCSWCD received in 2009.
