McGraw sits in the Trout Brook valley just east of Cortland, on the Appalachian Plateau. Valley-floor soils around the village run through Chenango gravelly loam and Howard gravelly loam on the outwash terraces, with Lordstown and Mardin channery silt loams dominating the surrounding hillsides and Wayland silt loam in the narrow floodplain itself.
Trout Brook drains west into the Tioughnioga River, and the combined watershed ties into the Cortland-Homer-Preble sole-source aquifer system that imposes stricter groundwater-protection requirements across the area. Commercial excavation in and around McGraw often deals with cobble-heavy outwash in utility trenches, shallow sandstone and siltstone bedrock on the valley walls, and seasonally perched water on the fragipan silt loam uplands. Frost depth is deeper than in lake-influenced counties to the north, pushing pavement, slab, and utility burial details. Projects along Trout Brook fall under NYSDEC stream-protection review in addition to Cortland County stormwater permitting. Projects near Trout Brook routinely require NYSDEC stream-protection review, and sole-source aquifer overlay mapping drives much of the stormwater infiltration design.
