What We Know About This Hamlet.
Commack straddles the Huntington/Smithtown town line roughly along Jericho Turnpike. Around 37,000 residents. Housing is predominantly mid-century ranch and split-level on quarter-acre to half-acre lots. Limited sewer coverage; most Commack homes are still on private disposal.
Commack has an aging housing stock: many homes built 1955-1975, original cesspools from that era are at or past end-of-life. Tank replacement is the dominant job type here.
What We Hit When We Dig.
Commack is a transitional zone between North Shore rocky till and central Suffolk sand. Expect:
- Sandy loam with pockets of rock especially north of 25A
- Moderate to good percolation
- Moderate water table (generally 10+ feet down)
- Standard lot access for most residential jobs
Article 6 in This Hamlet.
Standard process. Depending on which side of the town line you sit on, your permit either goes through Town of Huntington or Town of Smithtown on the town side, plus SCDHS on the county side. We coordinate both.
Usually Base-Tier Grant.
Most of Commack qualifies for the $20,000 SCSIP base grant. Some pockets near Nissequogue River headwaters or Sunken Meadow tributaries can qualify for enhanced $30,000. We check your exact address against the county sensitive-zone map.
See SCSIP Grant Guide.
