Project/Site: Piskula - 921093004 City/County: /Jefferson Sampling Date: 22 MAR 19
Applicant/Owner: Jon & Jennifer Piskula State: WA Sampling Point: 1 Upland
Investigator(s): W. David Loggy, Loggy Soil & Wetland Consulting SW ¼, Section 9, Township 29 N, Range 1 E.
Landform (hillslope, terrace, etc.): Shallow Swale Local relief (concave, convex, none): Concave Slope (%) 5
Subregion (LRR): A Lat: N 48.01859° Long: W122.68940° Datum: WAS 84
Soil Map Unit Name: MU Whc - Whidbey gravelly sandy Loam (see any correction in Soil Section
Remarks)
NWI: None
Are climatic / hydrologic conditions on the site typical for this time of year? Yes No (If no, explain in Remarks.)
Are vegetation , Soil , or Hydrology significantly disturbed? Are “Normal Circumstances” present? Yes No
Are vegetation , Soil , or Hydrology naturally problematic? (If needed, explain any answers in Remarks)
SUMMARY OF FINDINGS – Attach site map showing sampling point locations, transects, important features, etc
Hydrophytic Vegetation Present? Yes No
Hydric Soil Present? Yes No
Wetland Hydrology Present? Yes No
Is the Sampled Area
Within a Wetland? Yes No
Remarks: Vegetation is heavy grazed. Grass leaves are ≤ one inch in length and forb leaves are prostrate for the most part. The pasture on the
parcel is planted in pasture grasses and clover. Most of the grasses on the Peninsula are facultative or wetter. Pasture area is grazed year
around.
