Contents of the Plan

  1. Determining the contours of the terrain: levelling or other existing knowledge, such as a plan for a subsurface drain.
    • Clear targets achieved with a self-levelling laser or traditional optical levelling instrument; clearing in advance helps.
    • Tacheometer for large sites and for accurate contouring.
    • Laser scanning provides an extremely accurate model of the terrain. Taking a few adjustment measurements in the terrain will help to calibrate the relative elevations correctly.
  2. Drawing a draft of the plan on a map template: an overview of the wetland – what are we planning to do?
  3. Sizing the wetland’s weir structures and equipment. This should be done as accurately as possible, calculating for large floods that occur at least once in twenty years. A paved submerged weir or peak flow threshold is often the most secure and durable solution.
  4. Detail drawings: cross-section of the weir, water cross-section, etc.
    • The drawings should always be made case-specifically. It’s better to avoid copying ready models directly.
    • For many sites, a tidy drawing made to scale with a pencil is enough.
    • A tidy drawing can also include the measurements, in which case the drawing doesn’t necessarily have to be to scale.
  5. Making the map of the plan more accurate: the location of weirs, the shape of the waterfront, islands, areas with deep basins, etc.
  6. Writing the text part of the plan on the basis of technical information, detail drawings and maps.
  7. Compiling a budget.
    • It’s a good idea to find information about the actual costs of finished projects and about the equipment used.
  8. Recording the restrictions affecting the building of the wetland: things that must be taken into account in building it.
  9. The written consent of each landowner and rental agreements for the areas.
  10. Fine-tuning the plan and collecting the text part, the map and other appendices together.
