At a public middle school in south St. Louis County, Kuesel worked for the paving contractor on campus site improvements. Crews demolished a garage, a sidewalk canopy, pavement, sidewalk, fence, benches and signs, removed the old storm system and bio-retention basin, and regraded with about 1,400 CY of export.

With existing lines exposed by hydro excavation, Kuesel installed about 1,050 LF of 12" to 24" PE storm pipe with four manholes, three area inlets and seven 2-grate inlets, and rebuilt a 467 CY bio-retention basin with a stone weir and rock outlet protection, under MSD permits.
