Land Disturbance Activity

Land Disturbance Activity - The Land Disturbance Ordinance was adopted by the City of Mission Hills to reduce erosion and changes to stormwater drainage areas, as well as eliminate the introduction of sediment and pollution from construction sites and disturbed land into the City’s storm sewers, creeks, and adjoining properties.

The Land Disturbance Ordinance requires a permit for:

  • Changing the physical grade of a property from the natural grade,
  • The addition or removal of “fill”,
  • Changing the natural flow of stormwater on a property, and
  • Any elemental changes to a property caused by major landscaping or construction.

Tier 1 –Permit Required: If the land disturbance activity (LDA) falls within any of the parameters outlined below a Tier 1 permit will be required. No fees are assessed at this tier.
