A soil evaluation was completed at Garden Court (RE# 169716-0060) on July 20, 2022 (Figure
1). Three soil boring were completed to a depth of 72 inches to determine the seasonal high
water table based on soil morphology and the current water if observed (Table 1). The onsite
soils are mapped as Urban land-Leon-Boulogne complex and Boulogne fine sand (USDA,
NRCS SURGGO Data). These soils are poorly and very poorly drain with a seasonal high water
table between 0-18 inches below grade. Onsite soils are similar to Mandarin (Boring 1),
Hurricane (Boring 2), and Ridgewood (Boring 3).
Boring 1 (B1) is similar to the Mandarin series and is somewhat poorly drained. It has a spodic
layer from 26-38 inches, a seasonal high water table at 24 inches and a water table observed at
65 inches. The spodic layer is sandy but will have a slightly lower permeability than the sandy
soils above and below this layer. (Approx. Elev. = 9 ft)
Boring 2 (B2) is similar to the Hurricane series and is somewhat poorly drained. It has a spodic
layer from 60-72 inches, a seasonal high water table at 20 inches, and a water table observed at
54 inches. This soil also had some woody debris observed between 60-72 inches. The spodic
layer is sandy but will have a slightly lower permeability than the sandy soils above this layer.
(Approx. Elev. = 8.3 ft)
Boring 3 (B3) is similar to the Fripp series and is excessively drained. It is sandy throughout. It
does not have a seasonal high water table or water table within 72 inches. These soils have a
relatively high permeability rate. (Approx. Elev. = 17.1 ft)
Each of these locations has the ability to receive and infiltrate runoff from impervious surfaces
constructed onsite. If you have any questions regarding the onsite soils, please contact me.
