WETLAND DETERMINATION DATA FORM—Great Plains Region
Project/Site: Thunderbird Property City/County: Pueblo County Sampling Date: 8/13/2020
Applicant/Owner: Martin Marietta State: CO Sampling Point: SP-5
Investigator(s): MRF/TLM, Pinyon Environmental Inc. Section,Township, Range: S32,T2OS, R63W
Landform(hillslope,terrace,etc.): Oxbow Local relief(concave,convex,none): Concave Slope(%): 2
Subregion(LRR): western Great Plains Range and Irrigated Region Lat: 38.265770' Long: -104.474828' Datum: WGS84
Soil Map Unit Name: Bankard sand,0 to 2 percent slopes,frequently flooded NWI classification: R2UBH
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-5 is located in an abandoned channel of the Arkansas River. There is standing water approximately 3 feet west of SP-5 and the
water is covered by common duckweed. Much of the surrounding area is densely vegetated with Russian olive and tamarisk.
Hydrophytic vegetation, wetland hydrology, and hydric soils noted.
VEGETATION — Use scientific names of plants.
