FREE CONSULTATION Our free consultation addresses what information/documentation may be required by local, State and Federal regulating agencies for a specific site or project. Depending upon the goals for that site, several professional services may be required or none at all. The best way to find out is to contact us. Consultation can be done via phone, email or in person.
SOIL MAPPING (PERC TEST)
Sometimes referred to as a "Perc Test", soil mapping is the standard technique used to evaluate soil suitability for wastewater treatment systems (septic systems). Soil characteristics, observed through hand auger borings, along with site characteristics are used to determine the suitability of an area for both subsurface and surface wastewater treatment systems. Based on data collected in the field, a soil suitability report and suitability site map is generated. This documentation can be used as a tool for preliminary site planning, determining development potential, supporting property value, subdivision recordation, and other terrain altering activities."

WETLAND MAPPING
Wetlands are protected natural resources clearly defined by State and Federal Law. Soil Services utilizes the criteria set forth in Federal guidelines to delineate project sites. Positive indicators of hydric soils, hydrophytic vegetation, and wetland hydrology specifically distinguish wetlands. Our experienced staff collects site data through hand auger borings and field observations. A wetland delineation map and report is generated for confirmation with State and Federal regulating agencies. Once confirmed, this documentation can be used as a tool for preliminary site planning.

STREAM AND BUFFER EVALUATION
Often coupled with Wetland Mapping, the Stream and Buffer Evaluation classifies streams located within a project site and assesses their subjectivity to stream buffer rules (Neuse River, Tar-Pamlico, etc.). Like wetlands, streams are protected natural resources. Our experienced staff collects site data through approved classification techniques and field observations. A stream and buffer evaluation map and report is generated for confirmation with State and Federal regulating agencies. Once confirmed, this documentation can be used as a tool for preliminary site planning.

SEPTIC SYSTEM LAYOUT AND DESIGN
A septic system layout is a field representation of septic drain lines. Pin flags are placed on contour within a suitable soil area to show the extent and configuration of septic drain lines. Septic system layouts are used by local and State regulating agencies to field verify a proposed septic system for permitting. Septic installers also use septic system layouts as a guide for installing the septic drainlines. If you are not sure whether you need a septic system layout, contact us for a free consultation. Some sites may require a septic system design depending upon site and soil conditions. Innovative septic systems are used to maximize the development potential of a site. Soil Services is familiar with the newest wastewater treatment technologies and is well versed in on-site wastewater system design regulations. Our design staff provides economical and efficient wastewater treatment solutions to fit your needs. Our wastewater treatment design expertise include pressure manifold systems, low-pressure pipe systems, subsurface drip irrigation, pretreatment systems as well as residential National Pollutant Discharge Elimination Systems (NPDES).

FLOOD HAZARDS SOILS EVALUATION
Article 14 of the Wake County Unified Development Ordinance (UDO) protects these areas. Soil areas prone to frequent flooding with hydric soil indicators are known as Flood Hazard Soils (FHS). The Wake County Soil Survey is used as a guide to determine whether FHS may be present on a project site. A list of FHS can be found on in the Wake County UDO. The soil areas shown in the Wake County Soil Survey are often much larger than the actual FHS areas found on site. Therefore, a Flood Hazard Soil Evaluation may increase the development potential for a project site. Soil characteristics, observed through hand auger borings, along with site characteristics are used to evaluate a site. Based on data collected in the field, a FHS report and map are generated. This documentation can be used as a tool for preliminary site planning, determining development potential, and/or supporting property value.

STORMWATER BMP EVALUATION
Regulations for managing stormwater have been ever increasing and the criteria for suitable soil more stringent. The Stormwater BMP Evaluation utilizes hand auger borings to determine the soil characteristics in a proposed stormwater control measure (BMP) area. Field information is gathered to help guide stormwater design engineers choose the best BMP option for particular project and ensure the design meets the criteria set forth in the NC BMP Design Manual

HYDRAULIC CONDUCTIVITY TESTING (Ksat)
In situ Ksat testing is required for many development implements from stormwater infiltration basins to surface and subsurface pretreatment septic systems. Ksat testing measures the permeability rate of a soil under saturated conditions. This data helps design engineers determine the maximum efficacy of a particular project site. The number of hydraulic conductivity tests depend on the soil type and the requirements of the appropriate regulating agency (NC DWR, Local Health Department, NC DEQ, etc.) Weather can greatly alter the results of these tests, it is best to complete testing during warmer and drier seasons.
