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-8
Investigator(s): MRF/TLM, Pinyon Environmental Inc. Section,Township, Range: S32,T2OS, R63W
Landform(hillslope,terrace,etc.): Hillslope Local relief(concave,convex,none): None Slope(%): 8
Subregion(LRR): western Great Plains Range and Irrigated Region Lat: 38.264874' Long: -104.464246' Datum: WIGS 84
Soil Map Unit Name: Bankard sand,0 to 2 percent slopes,frequently flooded NWI classification: Rp1SS
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 No X
within a Wetland? Yes No X
Wetland Hydrology Present? Yes No X
Remarks:
SP-8 is located on the hillslope above SP-7, along the banks of the Arkansas River. The area is lacking hydrophytic vegetation,
wetland hydrology, and hydric soils.
VEGETATION — Use scientific names of plants.

Remarks: IDS-FAC Neutral Test for hydrology.Drop all FAC,cross examine all other dominants.Il 50%remaining are FACW to OBL,then YES to D5.
The vegetation passes the Prevalence Index. However, the area is lacking hydric soils and hydrology.
