WETLAND DETERMINATION DATA FORM—Great Plains Region
Project/Site: Thunderbird Property City/County: Pueblo County Sampling Date: 8/11/2020
Applicant/Owner: Martin Marietta State: CO Sampling Point: SP-3
Investigator(s): MRF/TLM, Pinyon Environmental Inc. Section,Township, Range: S31,T2OS, R63W
Landform(hillslope,terrace,etc.): Terrace Local relief(concave,convex,none): None Slope(%): 1
Subregion(LRR): western Great Plains Range and Irrigated Region Lat: 38.265960' Long: -104.493068' Datum: WIGS 84
Soil Map Unit Name: Las Animas fine sandy loam,0 to 2 percent slopes,frequently flooded NWI classification: Rp1 FO
Are climatic/hydrologic conditions on the site typical for this time of year? Yes X No (If no,explain in Remarks.)
Are Vegetation No Soil No or Hydrology No significantly disturbed? Are"Normal Circumstances"present? Yes X No
Are Vegetation No Soil No or Hydrology No 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 X No
Is the Sampled Area
Hydric Soil Present? Yes X No X
within a Wetland? Yes No
Wetland Hydrology Present? Yes X No
Remarks:
SP-3 is located on a terrace along an irrigation ditch. The banks of the ditch are steeply incised and small wetland patches are
present on terraced areas within the ditch. Hydrophytic vegetation, wetland hydrology, and hydric soils noted.
VEGETATION — Use scientific names of plants.
