A preliminary soil evaluation is performed to help determine whether a property may be suitable for future development and is commonly performed during a property's due diligence period. Generally referred to as a "perc" test. A few facts about preliminary soil evaluations:
This service is a great option for someone that is wanting to determine if a property may be suitable for a septic system prior to purchasing a property but does not need or does not have all the necessary information for an Improvement Permit (IP).
An Improvement Permit (IP) determines whether a property is suitable for a septic system based on the proposed building location, number of bedrooms (or occupancy, number of employees, etc.), and expected wastewater flow. This is the first step of permitting in North Carolina with traditional county permitting or hybrid (a2) permitting. An Improvement Permit is typically valid for a period of five years from date of issuance.
A Construction Authorization (CA) provides the construction details and specifications for a property that already has an Improvement Permit. Prior to issuance of a building permit, both an Improvement Permit and a Construction Authorization are typically required. This is the second step of permitting in North Carolina with traditional county permitting or hybrid (a2) permitting. The Construction Authorization is typically valid for as long as the Improvement Permit.

A hybrid (a2) permit combines private permitting with local health department involvement. Under this process:
This option is best suited for customers who live in counties with extended waiting periods for permitting with the local health department. This permitting option is more expensive than traditional health department permitting, but is a great option to limit health department involvement in permitting.
An Authorized Onsite Wastewater Evaluator (AOWE) Permit allows certain qualified professionals to perform private permitting for non-engineered septic systems. An AOWE Permit is completed by a NC Licensed Soil Scientist who is also an Authorized Onsite Wastewater Evaluator (AOWE) a NC Certified Septic Installer. This process allows the soil evaluation, design, and installation to occur privately, with the local health department serving primarily as the record keeper.
This option is best suited for customers who live in counties with extended waiting periods for permitting with the local health department. This permitting option is more expensive than traditional health department and hybrid (a2) permitting pathways.
An Engineer Option Permit (EOP) is a private permitting process that allows qualified professionals to complete the soil evaluation, design, and installation of a septic system without the local health department managing the permitting process. An EOP typically involves a NC Licensed Professional Engineer (PE), a NC Licensed Soil Scientist, a NC Certified Septic Installer. The local health department's role is generally limited to maintaining the official records. Triangle Soil Consulting can assist with fulfilling the licensed soil scientist role of the EOP permitting process and has multiple professional engineers it frequently works with.
This option is best suited for customers who live in counties with extended waiting periods for permitting with the local health department and generally requires a system that requires a professional engineer to design. This permitting option is more expensive than traditional health department and hybrid (a2) permitting pathways.
