Soil Drainage Management Plan
What is SDMP?
An SDMP, also known as an LMP (Land Management Plan), is a type of private sewage disposal system for poorly drained soils. It is a means for soils to accept sewage where the soils respond to artificial drainage. An SDMP requires a lot area of three (3) acres (excluding wetlands), surface grading in the subsurface soil absorption area of .5% and drainage ditches that surround the soil absorption area.
First Step – Where do I start?
If the property is zoned for single family, however cannot be served by City sewer, then fill out an Application for a Sewage Disposal and/or Water Supply Permit (form) from the Chesapeake Health Department. The Health Department will:
- Perform a soils evaluation on the property.
- Issue a CHS-201A form that prescribes type of sewage disposal system.
If the CHS-201A indicates an SDMP is required, then a plan is submitted to Public Works.

- CLS – Certified Land Surveyor
- Professional Engineer
- Property Owner (May not be able to perform exhibits for easements)
