Project Description

NicNevol Engineering Services conducted a geotechnical exploration and evaluation for a commercially zoned lot located at 1540 Baxley Road in Middleburg, FL. The study assessed subsurface soil and groundwater conditions to support the design of proposed retail buildings, parking areas, and a stormwater retention pond. :contentReference[oaicite:1]{index=1}

Field work included five (5) hand auger borings to ~6 ft depth and three (3) Standard Penetration Test (SPT) borings to ~25 ft depth. Groundwater was encountered at approximately 3.0–3.5 ft below grade. Subsurface conditions revealed surficial sands (SP) underlain by clayey sands (SC), clays (CH), silty sands (SM), and shallow limestone at 18–25 ft depth. :contentReference[oaicite:2]{index=2}

Recommendations included undercutting unsuitable clays, replacing with select structural fill or No. 57 stone, compacting to 95% Modified Proctor, and implementing groundwater and surface-water control during construction. Pavement design parameters included an 8 in. limerock base (LBR 100) with a 1.5–2 in. asphalt surface. :contentReference[oaicite:3]{index=3}

NicNevol Responsibilities
