- Geospatial_Data_Presentation_Form: vector digital data
- Description:
-
- Abstract:
-
The stormwater structures data is comprised of points (inlets, manholes, pipe ends, culvert ends, ponds, underground structures, and control devices). The pipe and culvert point structures, typically one at each end of the pipe/culvert line, include the stormwater infrastructure where there is a change in pipe direction. The data was collected primarily in eastern Loudoun in the more urbanized areas of the County. The data was collected in the field using GPS so that at least 95% of data is accurate to less than 3.28 ft. (1 m).
- Purpose:
-
Support of VPDES Phase II Stormwater Management Permit and County-wide storm water management. In support of the stormwater permit and the Stormwater Management program, regulated outfalls are identified and facilities that are inspected and repaired are tracked. Further, the data provides flow direction used to support pollutant travel analysis and the Illicit Discharge Detection and Elimination Program.
- Supplemental_Information:
-
Data are stored in the corporate ArcSDE Geodatabase as a point feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN, US Survey feet.

-
- Attribute_Accuracy_Report:
-
Stormwater has undergone extensive Quality Assurance procedures to ensure feature attribution is consistent with the data dictionary.
- Logical_Consistency_Report: Topologically Clean
- Completeness_Report:
-
Features may have been eliminated or generalized due to scale and intended use. To assist Loudoun County, Virginia in the maintenance of the data, please provide any information concerning discovered errors, omissions, or other discrepancies found in the data.

-
- Horizontal_Positional_Accuracy_Report:
-
At least 95% of data is less than 1 meter accurate using 95% precision setting of GPS when ACCURACY = RTD, otherwise locations were hand placed in field and accuracy is substantially less.
- Quantitative_Horizontal_Positional_Accuracy_Assessment:
-
- Horizontal_Positional_Accuracy_Value: Northing and Easting
- Horizontal_Positional_Accuracy_Explanation:
-
Raw GPS data files were reviewed for GPS readings including PDOP. Collection included a 10% recollection and cross correlation anayzed.

Stormwater Pipes underwent attribute-based edits to better organize the spatial database. One of the old attributes was renamed, two existing attributes had new values added to them in this latest edit, & two new attributes were added. CONSTRUCTION_DATE was renamed to CONSTRUCT_DATE; FEATURE & INVENTORY had one or more attribute values added, & MATERIAL_TYPE & ZONE_ID attributes were added to spatial database.

Stormwater Pipes also underwent attribute-based edits to better organize the spatial database in the May 2009 data update. Five of the old attributes were renamed, four new attributes were added, & seven were relocated within the attribute order. POND_TYPE renamed to BMP_TYPE, POND_SIZE renamed to BMP_SIZE, BASIN_W renamed to BASIN_W_FT, BASIN_L renamed to BASIN_L_FT, DEPTH renamed to DEPTH_FT, BMP_DRAIN_AC, BMP_DSGN_VOL_CYD, BMP_EXST_VOL_CYD, and MAJ_OUTFLL attributes were added to the spatial database.
