Exhibit 01
Property Lens
How does the property look on the ground?
Enlarge map ↗ (new tab)
The fictional Williamson property contains 23.86 mapped acres in one continuous parcel. The aerial places its shape, nearby road and wooded setting in context. Dimensions are approximate measurements of the scenario boundary, not surveyed lines.
The mapped property spans approximately 1,998 feet east to west and 591 feet north to south. For a real property, confirm boundaries and access records before relying on these screening measurements.
Exhibit 02
Access Lens
What needs to be confirmed about access?
Enlarge map ↗ (new tab)
The main parcel lies approximately 109 feet from the mapped Pine Hollow Road centerline. The broader view shows its connection toward US 401. This measures proximity to a line, not to a surveyed right-of-way or pavement edge.
Ask a surveyor and title adviser to identify intervening ownership, recorded easements and the legal access route. The road authority should also confirm driveway requirements.
How to read this exhibit
- Parcel outline
- The fictional main-parcel boundary.
- Road centerline
- Mapped road alignment, not its legal width.
- 109 ft
- Shortest planar distance between the scenario boundary and the road centerline.
Exhibit 03
Wetlands & Water Lens
Where do water features focus further investigation?
Enlarge map ↗ (new tab)
A mapped stream crosses the property, with about 0.71 acre of NWI forested wetland along part of the corridor. A 50-foot buffer on each side of the mapped stream centerline covers 3.61 acres within the parcel.
The blue buffer is a screening scenario. Applicable buffers can use different origins, water classifications and wetland boundaries; this shape does not establish a regulatory setback. A qualified environmental professional should locate stream and wetland boundaries in the field. Confirm applicable buffer provisions before planning crossings or site work.
How to read this exhibit
- PFO1A
- NWI palustrine, forested, broad-leaved deciduous, temporarily flooded wetland; an inventory classification.
- 50-ft buffer
- Analytical distance from a mapped centerline, not a field-established bank.
Exhibit 04
Terrain Lens
Where could slope constrain site layout?
Enlarge map ↗ (new tab)
Terrain above 15% slope occupies 4.69 acres (19.7%), including 1.08 acres above 25%. These areas help focus topographic, grading and erosion-control review. The 15% threshold is a selected screening criterion, not a determination that the land cannot be developed.
Detailed topographic survey and engineering work should confirm terrain at the scale needed for design.
How to read this exhibit
- Percent slope
- Vertical rise divided by horizontal distance, multiplied by 100. A 15% slope rises 15 ft over 100 horizontal ft.
- Overlapping totals
- The 1.08 acres above 25% slope are already included in the 4.69 acres above 15%. Do not add them together.
- Elevation source
- The analysis uses 2024 NC OneMap elevation data. Later grading or ground changes may not be represented.
Exhibit 05
Soils & Septic Lens
What septic limitations need closer evaluation?
Enlarge map ↗ (new tab)
Published component ratings, mapped using the dominant soil component in each map unit, classify 15.97 acres (66.9%) as Somewhat limited and 7.89 acres (33.1%) as Very limited.
This is a use-specific interpretation for septic tank absorption fields. It does not determine septic approval, system capacity or a drainfield location. Confirm sewer availability; where onsite wastewater is needed, obtain a qualified site evaluation.
How to read this exhibit
- Gold / tan: Somewhat limited
- 15.97 acres (66.9%). Some unfavorable soil features for septic absorption fields; appropriate design, installation or management may be needed. This color does not indicate approval.
- Purple: Very limited
- 7.89 acres (33.1%). One or more unfavorable features create substantial limitations requiring careful site evaluation.
- Map-unit codes
- ChA, GaC, GeB2 and GeC2 identify the soil-map units listed below. They are not severity levels.
- How the rating is assigned
- Each map unit uses the rated soil component with the largest published share. The Chewacla–Wehadkee unit is Very limited; the Georgeville units are Somewhat limited. Soil components are mixed within units and are not individually located on this map.
- What the percentages mean
- 66.9% and 33.1% describe mapped property area. Soil-component percentages describe composition within a map unit; they are not property-area percentages or failure probabilities.
- Published limiting factors
- The dominant Chewacla component has flooding, shallow saturation and water-movement concerns. The Georgeville components identify slow water movement. The full report provides the component details and method.
| Code | Soil map unit | Acres | Rating |
|---|---|---|---|
| ChA | Chewacla and Wehadkee soils, 0 to 2 percent slopes, frequently flooded | 7.89 | Very limited |
| GaC | Georgeville silt loam, 6 to 10 percent slopes | 5.98 | Somewhat limited |
| GeB2 | Georgeville silty clay loam, 2 to 6 percent slopes, moderately eroded | 4.26 | Somewhat limited |
| GeC2 | Georgeville silty clay loam, 6 to 10 percent slopes, moderately eroded | 5.72 | Somewhat limited |
Areas and percentages are rounded independently. NRCS interpretations are screening information and do not establish site-specific soil conditions, septic suitability or regulatory approval.
Exhibit 06
Combined Constraints Lens
How do the selected constraints overlap?
Enlarge map ↗ (new tab)
The selected features cover 7.60 acres (31.8%), counting overlaps once. The remaining 16.26 acres lie outside this particular footprint.
The remainder is not confirmed buildable land. Soil limitations, access, utilities, planning conditions and other untested constraints remain separate.
How to read this exhibit
- Selected layers
- Mapped wetlands, the 50-foot stream-buffer scenario and slopes above 15% are merged into one footprint. Overlapping areas are counted once.
- Outside the footprint
- 16.26 acres (68.2%) lie outside these selected features. Septic limitations and other constraints are not included in this combined footprint.
Exhibit 07
Flood Risk Lens
What does the published flood map show?
Enlarge map ↗ (new tab)
The entire scenario parcel intersects Zone X, labeled Area of Minimal Flood Hazard in the reviewed NFHL layer. No Special Flood Hazard Area intersects the parcel in that layer.
Zone X does not rule out localized drainage problems, shallow groundwater or flooding outside the mapped special-hazard area.
How to read this exhibit
- Zone X
- The reviewed layer labels the parcel Area of Minimal Flood Hazard. This is a mapped classification, not a guarantee against flooding.
- Zero overlap
- The zero result applies to Special Flood Hazard Areas, not to all FEMA map features or all types of flood risk.
- Source dates
- FEMA data were reviewed on 24 September 2026; the source map panel became effective on 17 November 2017.
Exhibit 08
Wildlife & Habitat Lens
Does mapped federal critical habitat overlap?
Enlarge map ↗ (new tab)
No features in the reviewed final or proposed federal critical-habitat layers intersect the scenario parcel. The test includes both polygon and linear designations.
This finding does not establish that protected species are absent. Habitat conditions, species records and field studies answer different questions. Additional wildlife studies could identify constraints arising from protection of species that use these habitats.
How to read this exhibit
- Four checks
- Final and proposed critical-habitat polygons and lines were checked. Each of the four layers returned zero parcel intersections.
- Scope of the result
- Critical-habitat designations do not inventory all wildlife or prove species absence. A qualified biologist can advise whether species records review or field surveys are warranted.
Exhibit 09
Zoning Lens
What planning classification needs confirmation?
Enlarge map ↗ (new tab)
The mapped classification for the main parcel is R-A-2, Residential-Agricultural. The wider map shows neighboring districts and road context, with the subject boundary distinct from road lines.
The source district is intended primarily for very low-density residential use alongside agriculture and forestry. Its name and nominal two-acre standard do not establish a lot yield or authorize a particular project. Confirm the district, overlays, intended use and parcel-specific conditions with the planning authority. Minor source-boundary misalignment remains, so this map is not a surveyed zoning-boundary determination.
Exhibit 10
Future Land Use Lens
How does the property fit the planning direction?
Enlarge map ↗ (new tab)
The town future-land-use layer places the main parcel in the Residential character area. The wider view shows Employment Mixed Use, Mixed-Use Activity Center, Rural / Conservation Design and Open Space nearby.
These are policy categories, distinct from current zoning. Residential policy anticipates housing in relation to infrastructure and surrounding character; it does not confirm sewer capacity, a rezoning or development approval. Confirm the adopted plan and subsequent amendments with the planning authority. Ask utility providers about connection points and capacity, and read this exhibit alongside current zoning and the environmental screens.
