Planning and Development Plan Review

The Planning and Development Plan Review, also known as a Setback Distance Review, is used to determine if the proposed development (including, but not limited to, non-livable space, patios, paved surfaces, block walls, fire pits, swimming pools, or similar structures) will maintain an adequate setback distance to the parcel’s existing onsite wastewater treatment facility or septic system and designated reserve area for parcels that utilize a septic system to manage their wastewater.

Common Required Setback Distances to a Septic System 


  • 10' to structures
  • 10' to covered patios
  • 5' to edge of excavation for swimming pools
  • 5' to driveways or paved surfaces
  • 5' to block walls or fences

Public Record Request



Public Record Request is required before submitting a Planning and Development Plan Review to ensure that any structures added to the property meet setback requirements to the existing septic system on file.

Planning and Development Plan Review Outcome



If, after the Planning and Development Plan Review, MCESD determines the proposed development does not meet the minimum required setback distances to the existing septic system or designated reserve area, an Alteration to replace either the tank or the disposal field, or a NOID application to replace the tank and the disposal field, may be required.
