Packinghouse Block Soil Classification Epipedon – Umbric Epipedon – Umbric Subsurface horizon – Spodic Subsurface horizon – Spodic Order - Spodosol Order - Spodosol

Packinghouse Block Pedon Properties and Interpretations Infiltration Rate = High Infiltration Rate = High Hydraulic conductivity = High Hydraulic conductivity = High Available water = Low (10.7 cm) Available water = Low (10.7 cm) Soil wetness class = Class 3; cm Soil wetness class = Class 3; cm

Packinghouse Block Pedon Properties and Interpretations (Cont.) Soil Interpretations: Soil Interpretations: Dwellings with basement = moderate limitations Dwellings with basement = moderate limitations Septic tank absorption fields = severe limitations Septic tank absorption fields = severe limitations Local roads and streets = slight limitations Local roads and streets = slight limitations

Packinghouse Block Site Characteristics Position of Site = Upland Position of Site = Upland Parent Material = Marine Parent Material = Marine Soil Slope = Nearly Level (0-2%) Soil Slope = Nearly Level (0-2%) Surface Runoff = Very Slow Surface Runoff = Very Slow Erosion Potential = Very Low Erosion Potential = Very Low
