Project/Site: Thunderbird Property City/County: Pueblo County Sampling Date: 8/12/2020
Applicant/Owner: Martin Marietta State: CO Sampling Point: SP-4
Investigator(s): MRF/TLM, Pinyon Environmental Inc. Section,Township, Range: S31,T20S, R63W
Landform(hillslope,terrace,etc.): None Local relief(concave,convex,none): Concave Slope(%): 1
Subregion(LRR): western Great Plains Range and Irrigated Region Lat: 38.265930' Long: -104.493089' 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 No X
Is the Sampled Area
Hydric Soil Present? Yes No X X
within a Wetland? Yes No
Wetland Hydrology Present? Yes No X
Remarks:
SP-4 is located in the upland area adjacent to the irrigation ditch, above SP-3. Area lacking hydrophytic vegetation, wetland
hydrology, and hydric soils.
VEGETATION — Use scientific names of plants.
