On June 30-July 1, 2017 an extreme rainfall event caused the lateral migration of the of Tributary 26 to Butternut Creek located south of Colton Road in LaFayette, New York. The migration of the stream channel caused undercutting and erosion of the stream bank to the east and deposition of new point breaks downstream.
Tributary 26 looking southerly. Eroded streambank visible on left (east).
In collaboration with Dr. Ted Endreny from SUNY ESF and the Onondaga County Soil and Water Conservation District, NSE developed a design plan for the restoration of this stretch of Tributary 26 and was intended to reclaim riparian area east of the creek for the landowner and implementing conservation and restoration techniques intended to prevent future lateral migration of the creek and preserving it’s natural function. The design followed Rosgen stream restoration principles and consisted of:
reestablishment of the creek channel to the west
bendway weirs to deflect and dissipate energy away from the eroding east stream bank
rock riffles and large stones to dissipate energy within the newly reestablished stream channel
dogwood plantings in the reclaimed floodbank and fascines to protect the edge of bank.
Design plan for Tributary 26 Restoration
Construction was initiated per the design plan by the selected contractor J&J Landscaping the week of November 27, 2017 and earthwork completed on December 8. Plantings to follow in mid-December.
Reestablished creek looking southerly from Colton Road.
Assuming continuing adaptive management measures to be informed by the landowner, the reestablished creek and energy dissipation measures will provide for a stable planform, yet able to pass extreme events via a connected functioning floodplain.
With funding under Onondaga County’s award-winning Save the Rain program, Crest Acura’s porous asphalt lot was completed this summer. The project was designed by Natural Systems Engineering and constructed by Lan-Co Construction (East Syracuse, New York). The porous asphalt was designed to capture runoff from the 10,000 sq ft porous surface and the 9950 sq ft impervious asphalt lot located to the northeast. Roughly 1000 sq ft of greenspace was added to replace asphalt in the right-of-way of the City of Syracuse.
The project will manage a minimum of 400,000 gal of strormwater per year, removing that flow from Syracuse’s combined sewer system.
Individual Projects can Receive up to $1 Million Rebate Depending on Size
The New York State Energy Research and Development Authority (NYSERDA) announced on May 30 the availability of $15 million in rebates for the installation of ground source heat pump systems for residences, businesses and institutions. The announcement states that “renewable heating and cooling technologies such as ground source heat pumps not only provide environmental benefits but also provide energy bill savings, increased comfort levels and health benefits compared to conventional heating and cooling technologies.”
The amount of funding available to each project will depend on its size. Smaller projects (e.g., residential and small commercial buildings) can receive up to $15,000 when the installation is completed. A typical residential system will qualify for about $6,000. Larger projects (e.g., multi-family, hospitals and college campuses) can receive up to $500,000 per building with payments being made throughout the project. No single site can receive more than $1 million.
Rebates will be available to qualified installers for two years or until all funds have been exhausted. The total amount of the rebate will be deducted from the total cost of the system, thereby passing the savings along directly to consumers. Any ground source heat pump system for which installation was complete on or after January 1, 2017, and that meets the requirements of the program, is eligible. Only participating, qualified designers and installers may submit applications. Natural Systems Engineering is such a provider!

Front Yard Geothermal Drilling – Tipperary Hill, Syracuse
In November 2016, construction was substantially completed for the Gear Factory Porous Asphalt lot serving the northern 200 block of South Geddes Street. The project involved conversion of impervious alleys and a parking lot associated with the Gear Factory building and the building housing City Hardware into a porous asphalt lot and infiltration basin, which will manage runoff from the 19,000 sq ft of impervious hardscape and almost 15,000 sq ft of rooftop. The project will manage roughly 630,000 gal of runoff annually preventing that volume of runoff from entering the City of Syracuse’s combined sewer system and mitigating combined sewer overflows from that system.
Bottom Slope/Fish Ramp at Ley Creek (pre-existing stone dam on the left)
Streams and lakes in Onondaga County in Central New York area have been significantly altered and degraded as a result of urbanization and industrialization. Located in the Lake Ontario watershed, the area is eligible for funds under the Great Lakes Restoration Initiative for habitat improvements in the watershed. In 2010, the Izaak Walton League of America (IWLA), secured funding under the GLRI for restoration measures in the Onondaga Lake watershed.
Following the successful restoration of Beartrap Creek in Salina, New York in 2010, an additional habitat restoration effort was undertaken in the South Branch of Ley Creek in DeWitt, New York. The Central New York Chapter of the IWLA, in consultation with the Onondaga Environmental Institute (OEI), identified a low head stone dam suspected as acting as an impediment to upstream migration of walleye and northern pike for spring spawning as an opportunity for improvement. Natural Systems Engineering designed a stone bottom slope (or fish ramp) consisting of field stones placed to the toe of the dam to allow fish passage during periods of higher streamflow. Partners on the project include Joe Green Excavating (Phoenix, New York) for construction, OEI for pre- and post-construction biota monitoring, and the Central New York Chapter of the IWLA who was instrumental in site selection and logistics.
In the late summer and early fall, the urban retrofit geothermal project located at 248 Bryant Avenue in Syracuse, New York was completed. Pipes were fused and run into the basement and pressure tested. The wells were then grouted with a flowable cementitious grout (See Photograph 1).
Following completion of the site work, the mechanical contractor, Renaissance HVAC (Verona, New York), completed the installation of the 4-ton GeoStar Cypress Combination heat pump see Photograph 2). Wells were completed by purging and filling with a 20% ethylene glycol solution for freeze protection. The combination heat pump system allows the heating of the house both with air and radiant hot water and air conditioning in the summer. The geothermal heat pump will be powered by the grid-connected 6.4 kW solar array mounted on the home’s rooftop.
Piping and the heat pump system were provided by Phoenix Energy Supply who, along with Renaissance HVAC, also provided tremendous support on this challenging project! The next steps on the path to net-zero are to connect domestic hot water to a heat pump and switchout the natural gas fueled stove and oven!
The Ra-Lin “Save the Rain” project designed by Natural Systems Engineering was featured on WSYR News Channel 9 on September 30, 2016. The project involved construction of approximately 16, 000 sq ft of porous asphalt and a bioretention area to manage stormwater runoff from the 1.5 acres of impervious areas at the discount appliance store located on Burnet Avenue in Syracuse. The project will result in the management of over 1.2 million gallons of stormwater annually, preventing that volume from entering the storm sewer system and contributing to combined sewer overflows to Onondaga Lake. The story on Channel 9 shows how the porous asphalt allows infiltration of rainwater through the porous surface.
Natural Systems Engineering’s urban retrofit geothermal project was featured on YNN’s “Going Green” program on May 16, 2016. Ground source heat pumps will be powered by existing roof top solar panels. Check back for follow up story later this year.
Drilling was completed on May 12, 2016 for an urban retrofit geothermal system being installed at 248 Bryant Avenue in Syracuse, New York. Two vertical closed loops of 300 ft each were set in two wells and will serve the 4-ton combination heat pump system yet to be installed. Drilling was initiated using an air rotary rig, but was switched to a cable tool rig on the second hole when water was pushed back through the first hole through a void in the bedrock geology. Water was encountered in each hole, but was contained on-site. Saline groundwater was a concern, but wasn’t encountered until ~280 ft depth. System design by Natural Systems Engineering. Drilling performed by Caster Well Drilling and Water Conditioning (Fulton, New York).
