(6) UTILITIES — Eversource Energy (formerly CL&P, rebranded 2015) is the electric utility; Southern Connecticut Gas (SCG) is the gas utility. (7) CTDOT ENCROACHMENT PERMITS — driveways or work within state highway right-of-way (Route 5, Route 17, I-91, I-691 in/near North Haven) require Connecticut Department of Transportation encroachment permits. (8) NATIVE AMERICAN HERITAGE — Quinnipiac Indian heritage acknowledged; the Connecticut State Historic Preservation Office (SHPO) requires consultation for state- or federal-funded projects in archaeologically sensitive areas. (9) SEPTIC / WELL — most North Haven parcels are on the South Central Connecticut Regional Water Authority public water and Greater New Haven Water Pollution Control Authority sewer; rural northern parcels may be on private well/septic regulated by the Quinnipiack Valley Health District (QVHD).
