Filling And Grading / Land Disturbing Activities

Langlade County Ordinance

A fill and grade permit shall be required for any filling, grading or excavating within 300 feet of a navigable water body. Best management practices must be adhered to as specified in the DNR Construction Site Erosion Control Manual.

  • Erosion control practices shall be required within 100 feet of the OHWM of lake or stream on slopes greater than 5% and on projects within 25 feet of a property line. The area of soil exposed and duration of exposure shall be minimized.
  • No heavy equipment can be used within 75 feet of OHWM of a lake or stream.
  • A conditional use permit shall be required for fill and grade areas exceeding 10,000 square feet.
  • Land disturbing activities are prohibited on slopes greater than 45%. Permits are required for excavating a pond.

Why we have this in our ordinance

Plants and trees help hold soil and prevent erosion, especially on steep slopes. Removing them as you construct your home increases the chance for soil erosion. Soil erosion can lead to structural damage, reduces soil fertility, and harms lakes and rivers by causing excess sedimentation, killing aquatic bottom life, and disrupting spawning. The sediment, with accompanying nutrients, leads to algal blooms, decreases lake depth, and reduces aesthetic appeal. All of these potential problems are expensive to correct and, more importantly, can be avoided by proper water and land use practices.

What you can do...

Follow these guidelines for erosion control during and after construction. Erosion control practices must be installed PRIOR to any land disturbing activities and must remain in place until the site is stabilized (no bare soil).

  • Minimize disturbance of the existing groundcover layer to avoid soil erosion,
  • Keep the construction site covered with a hay or straw mulch immediately after seeding or reseeding.
  • Consider working only in a small area and stabilizing that site before disturbing another,
  • Protect groups of trees from heavy equipment by encasing them with snowfence. Avoid compacting soil above tree roots by excluding heavy equipment and not stockpiling building materials over roots,
  • Maintain a filter strip of natural vegetation along the banks of lakes and streams; the best filter strips are native trees with undisturbed native understory plants,
  • After your structure is in place, plant a temporary cover crop on all areas that have been disturbed (e.g. annual rye grass) until permanent trees, shrubs and groundcover plants can be added,
  • Trees, shrubs and groundcover plants are excellent at protecting soil from the effects of rain and are practical erosion-control measures. Native trees, shrubs and groundcover plants should be used wherever possible as they create a natural, minimum maintenance landscape.
