Classifications &
Reclassifications

To start,
CGA gathers the following

  • Existing Classification (preferable in Excel format) from applicable Drainage Clerks
  • Soil Surveys from USDA website
  • Maps of District Boundaries and Facilities from applicable Drainage Clerks
  • Aerial/Tract Maps from applicable county GIS website
  • Recorded Boundary Surveys from applicable Recorder’s Offices
  • LIDAR elevation data

CGA’s
Workflow

Once gathered, CGA analyzes the data:

  • Boundary Generation
    Unless shown on existing maps, this step generates the applicable watershed limits or boundaries using LIDAR elevation data.
  • Tract Verification
    The second step verifies that each tract number is appropriately sized and creates tract numbers as needed.
  • Acreage Verification
    The third step verifies that the existing acreages match recorded boundary surveys.
  • Acreage Generation
    The fourth step generates acreages for all the remaining tracts.
  • Soils Type Determination
    The fifth step differentiates the soil types for each tract based on their properties.
  • Proximity Determination
    This sixth step measures the distance from each tract to the District facilities.

Your data has
been analyzed.

Now what?

#1

CGA then reviews the above data with the landowner commissioners to determine appropriate factors for soils and proximity to determine the most benefit tract.

#2

This review is coordinated with field visits and review of any tracts with possible exceptions to the above process.

#3

Using these, the commission determines the most benefited tract within the watershed (i.e. the 100% benefited tract) and ranks all other tracts in comparison to it.

The Last Step!

CGA generates reports containing a written description of the process, maps showing the watershed, tables showing the data for each tract, and commissioner certifications.

These reports are then submitted to the District Trustees and hearing date set. CGA attends the hearing to explain the above process and answer questions from landowners and District Trustees.

As always, CGA is available to answer questions throughout the process, too.
