Local project context

Planning a septic system for a Hodge property

Hodge is a very small, dispersed desert settlement along I-15 southwest of Barstow.

Remote access, washes, private wells, sparse utility records, and broad undeveloped acreage make precise parcel identification essential.

A septic system design should follow the actual buildable footprint and wastewater demand. The home, grading, driveways, utilities, wells, drainage, setbacks, and a future replacement area all affect whether a layout can work.

Jurisdiction and sewer service

Confirm the review path before field work

Hodge is an unincorporated County planning community rather than a municipality or Census place.

Jurisdiction depends on the parcel. County EHS is the technical-review agency for unincorporated County work, while incorporated projects begin with the applicable city and may involve County EHS, a sewer district, and a Regional Water Board. For County-reviewed work, current LAMP and percolation-report requirements should be confirmed with the agency for the specific parcel.

Check the reviewing agency

01
Verify whether the parcel is in an incorporated city or unincorporated County area.
02
Confirm whether a public sewer connection is available or required before planning an onsite wastewater treatment system.
03
Match the percolation report, soil profile, proposed wastewater flow, site layout, and replacement-area requirement in one design basis.

Design and permitting

From Hodge site evaluation to septic design

A useful septic plan connects the site's soil and percolation evidence to an approvable layout and the next permitting step.

01
Confirm the parcel and review path
Start with the address or APN, proposed use, city or County boundary, public-sewer availability, and any direction already received from the reviewing agency.
02
Establish the site and soil basis
Review the percolation report, soil profile, grading concept, slopes, drainage, wells, setbacks, groundwater or bedrock evidence, and the space available for the proposed system.
03
Lay out the primary and replacement areas
Coordinate the building, access, utilities, grading, and wastewater flow with a usable dispersal area and the replacement area required by the applicable agency.
04
Prepare a parcel-specific design package
Document the design assumptions, system components, calculations, site layout, and supporting information needed for the next agency review and permit step.

Parcel-specific scope

Design information to resolve

The final septic layout and sizing depend on more than a percolation number. The design must fit the parcel and meet current agency, public-health, and water-quality requirements.

Remote access
Sparse utility records
Private wells
Parcel and access verification
Correct parcel, proposed land use, bedroom count or design flow, and responsible reviewing agency
Representative primary and 100-percent replacement areas that remain available after development
Measured percolation behavior plus soil logs at the proposed dispersal depth
Highest known groundwater, bedrock or restrictive layers, fill, drainage, flood features, and slope

Property-owner questions

Septic system design in Hodge

Who reviews septic design for a property in Hodge?+

Hodge is an unincorporated County planning community rather than a municipality or Census place. For unincorporated County parcels, San Bernardino County Environmental Health Services normally handles technical OWTS review. Confirm the exact agency and sewer status from the parcel before designing or submitting.

Does a perc test by itself approve a septic design in Hodge?+

No. Percolation results are one design input. The reviewer also considers the soil profile, groundwater and bedrock separation, slope, setbacks, wastewater flow, grading, sewer availability, and the required replacement area.

Can a septic system be designed before testing is complete?+

A preliminary feasibility review can begin with the parcel information and concept plan. Final sizing and a permit-ready layout depend on the applicable agency's requirements and adequate site-specific soil and percolation information.
