Re: Flood Hazard Soils Evaluation
14.68 Acre Tract Located at 5290 Yates Mill Rd
Raleigh, Wake County, N.C.
PIN No. 0782-24-2036
Dear Mr. Al-Zoubi:
On June 11, 2018, Soil Services, PLLC (Soil Services) performed a flood hazard soils evaluation
on the property referenced above at your request as part of the preliminary planning process. The subject
property is approximately 14.68 acres in size and is located 5920 Yates Mill Pond Rd in Raleigh, Wake
County, NC. The site currently consists of a vacant single story home, grass lawn and undeveloped
forested land.
Wake County Regulations
Flood hazard areas of the county are subject to periodic inundation that may result in loss of life
and property, health and safety hazards, disruption of commerce and governmental services, extraordinary
public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely
affect the public health, safety or general welfare (Article 14-10-1). Uses of flood hazard areas are
restricted or prohibited by Wake County under Article 14 of the Wake County Unified Development
Ordinance (UDO). The Wake County Planning Department uses transparent photographically enlarged
maps (3 to 4 times the scale of maps as printed) of the published SCS Wake County soil survey to alert
them to alluvial soils (flood hazard areas), which introduces distortion of soil boundaries in valleys of
small streams. In the process, the linear extent and width of the "flood hazard soil" areas can become
greatly exaggerated, especially at the head of drainways and/or large floodplains. Wake County realizes
the potential for incorrect or misplaced flood hazard soil areas, thus Article 14 also specifies the steps
necessary for a licensed soil scientist to classify and/or modify flood hazard areas.
Results
Prior to the field investigation, flood hazard soil areas within the project boundaries were
identified per Wake County GIS as mapped by the Wake County Soil Survey (November 1970). The
following Wake County flood hazard soil units are mapped within the project boundaries:

During the field investigation, hand auger boring locations and the boundary of flood hazard
areas were flagged and located with a GPS receiver as shown on the attached evaluation map. Standard
techniques of the USDA Soil Survey Program were utilized in this evaluation, which included making
hand auger borings to depths sufficient for soil identification to the series level, and recording profile
descriptions for flood hazard soil and upland soil in accordance with the Field Book for Describing and
Sampling Soils, reference USDA-NRCS. Observations of the landscape topography such as slope,
drainage patterns, etc. were recorded along with soil properties such as soil horizon, depth, texture,
structure, wetness, and matrix and mottle color. Soil matrix and mottle hue and chroma color were
determined by the use of a Munsell Soil Color Chart. The soil profile descriptions for each hand auger
boring are included with this report.
In reality, based on our field investigation, several areas are incorrectly identified as containing
flood hazard soils and conversely there are several areas incorrectly identified as having upland soils that
have flood hazard soils. These soils have been reclassified to the most appropriate upland or flood hazard
soil series. The representative soil boring number, original soil series, and revised soil series if applicable
are presented in Table 2. Based on this information, along with other information gathered on the site, a
revised flood hazard soil map was produced and is enclosed with this report.

Conclusion
In conclusion, the findings presented in this report and represented on the attached map reflect the
professional opinion of Soil Services based on our site and soil evaluation. Therefore, the flood hazard
soil delineation has been revised to adhere to actual soil conditions, drainage features, and
topography/landscape position as shown on the attached map.
Soil Services, PLLC would be pleased to assist you in any future site analysis needs. Please
