Proposed network · routed on 1 m terrain

Routed on the common tracts and road edges, off private house lots: snowman loops in the two flat meadows, joined by a connector through Tract K and a traverse across the upper bench of Tract D. Grades stay under 8% where possible, and the routes skirt the willows and timber mapped from infrared imagery. The snowmen give skiers a big and a small loop joined at a waist, with no at-grade crossing; sign them one-way. Dashed orange marks where the side slope is over 15%, so the trail needs a cut catwalk.

About this model

Area shown: . Elevations . Terrain grid is about 19 m (63 ft), so short pitches under that length are smoothed out; IMEG's 1-ft contours are the reference for final layout. Lot lines are the county parcel layer and are not a survey. Proposed routes were measured on the 1 m USGS lidar terrain; the willow layer is an automated classification of NAIP infrared (live, leafy shrub in low, wet ground) and should be ground-truthed.
