Map-plan proposes sewer district along Cayuga Lake shoreline; $33 million build could get up to $15 million in state grants

Consultants for a proposed shoreline sewer told the Cayuga County Legislature on May 20 they have prepared a map, plan and report for a partial county sewer district along the Cayuga Lake shoreline and will ask the legislature next month to form the district so the project can pursue state grant funding.

Tim Carpenter of MRV Group described the project as a low-pressure sewer system intended to protect lake water quality by routing wastewater from properties along the lakeshore to the Village of Aurora wastewater treatment plant, which would receive an upgrade as part of the scheme. The proposed district would not cover entire towns but the shoreline areas in the towns of Genoa and Ledyard down to the Tompkins County line.

Key figures and grant strategy

Carpenter estimated construction at about $33 million, noting a 25% contingency in the planning estimate; he said available grant funds in the current round could total as much as $15 million. He told legislators that forming a sewer district is a precondition for some state grants and that the map-plan-report itself does not obligate the county or residents to costs — the financial obligation would be established later and shared only among those properties that benefit.

Carpenter gave an early example of what remaining resident costs could look like under one scenario, saying that with sufficient grant funds the burden might translate to roughly $2,000 per year per home; he stressed the figure depends on final grant awards and other design details and would be revisited before a decision to proceed.

Why it matters

Consultants and county staff emphasized the environmental rationale: the project would reduce phosphorus and nitrogen inputs to the Finger Lakes and address septic-system failures on densely occupied lakeshore roads. The application window for the New York State Environmental Facilities Corporation and other grant programs was described as opening in the current cycle; consultants said awards would be announced in late fall or early winter and that having a formed district improves competitiveness.

Next steps

MRV Group asked to return to the legislature next month for a public meeting and a potential resolution to form the partial county sewer district so the grant application can be submitted in July. If grant awards are announced in November or December, consultants will return with the estimated remaining costs and recommended next steps for property owners and the legislature.
