Suburban Green Infrastructure Program (SGIP)

Fayetteville Streetscape 1Funding purpose:

The purpose of Onondaga County’s Suburban Green Infrastructure Program (SGIP) is to support the development of green infrastructure and stormwater mitigation techniques on public property within the Onondaga County sanitary sewer district but outside of the City of Syracuse. Eligible municipalities can apply to receive financial incentives for the installation of Green Infrastructure (GI) Technologies, including but not limited to:

• Rain gardens
• Bioretention
• Dry wells
• Underground infiltration systems
  • Green roofs
• Porous pavement
• Tree plantings
• Tree trenches
  • Planter boxes
• Cistern systems
• Added green space

Other eligible innovative infrastructure projects are methods of repairing sewer infrastructure that does not require road reconstruction, including but not limited to sewer lining, manhole repair with epoxy grout, and removal of cross-connected storm sewers. These innovative projects require minimal excavation and will significantly reduce the amount of fuel, steel and asphalt needed when
compared to conventional rehabilitation or replacement activities.

This program supplements the highly successful Save the Rain program investments already underway in the City of Syracuse, with programming focused on projects outside the city to control stormwater runoff and inflow and infiltration into the sanitary sewer system.

Funding eligibility:

SGIP funding is aimed at municipal entities within Onondaga County that are planning projects to reduce inflow and infiltration to the sanitary sewer system. All eligible projects must be on municipally-owned property within the Onondaga County sewer system. Applicants must provide evidence of a fee-simple title to the public property to be improved, with the exception of potential
rain barrel retention projects which may be utilized in conjunction with private property. Eligible reimbursable expenses include design and engineering costs as well as labor and material construction costs.

Program procedures:

The SGIP involves a four-step process, as follows:

  1. Completion of a program application
  2. Approval by Onondaga County WEP
  3. Construction
  4. Reimbursement

Specific requirements, procedures, and selection criteria are described in further detail in the SGIP application form.

SGIP projects:

The first round of SGIP funding, in the amount of $3,000,000, was allocated in 2012 for the abatement of sewer system overflows and mitigating inflow and infiltration with 14 projects selected in 12 municipalities. The second round of SGIP funding, in the amount of $2,000,000, was distributed in 2013 for the abatement extraneous flow into the sewer system, mitigating inflow and infiltration with green and innovative infrastructure technologies. Additional projects were funded in 2014, and 2017 through the annual budget process.
