The ground, and what fits on itSlope map — measured classes over bare-earth hillshade. Approximate boundary from public GIS — not a survey.
Candidate pads — drawn at true footprint size, numbered by rank; earthwork is an order-of-magnitude range balancing cut against fill, excluding clearing, rock, access, drainage and retaining structures.
Views — horizon angles measured over bare earth; standing timber can screen any line of sight.
| Class | Range | Share | Acres | Percent |
|---|---|---|---|---|
| Ideal | 0–10% | 3.08 | 4% | |
| Moderate | 10–15% | 1.71 | 2.2% | |
| Challenging | 15–20% | 2.73 | 3.5% | |
| Difficult | 20–30% | 10.64 | 13.8% | |
| Severe | Over 30% | 58.99 | 76.5% |
Ground is steep and consistently so: the median is 41%, close to the 40.6% mean, so the slope is spread across the parcel rather than concentrated in one face. 76.5% of the study area falls in the steepest class. The 6% under 15% is where building, access and septic all compete for the same ground.
Aspect and views
The ground faces mostly SW (29%) and W (23%). The gentle ground faces predominantly S (30%). From the strongest candidate area, nothing in the modeled terrain rises to block the line of sight to the SE, S, SW, W (horizon at 0° or barely above it) — consistent with long-range views that way; ridgelines close in to the NE (17.1° at the steepest), holding those views short-range.
- Steepness is spread across the whole study area rather than concentrated in one face — the median (41%) sits close to the mean (40.6%).
- Most of the study area — 76.5% — falls in the steepest class.
- 4.79 acres (6%) sit under 15% slope. Building, access and septic all compete for that ground.

- The largest candidate is 15,140 sq ft — comfortably above the 2,000 sq ft minimum searched for, so size is not the binding constraint here.
Solar exposureSun hours — modeled per grid cell from slope, aspect and the terrain horizon on three representative days; a clear-sky ceiling before trees and weather, not a production forecast. Winter is the test that matters.
Canopy — published tree-canopy mapping; the sun hours are terrain-only, so canopy is how much standing timber stands between them and a panel.
Method — the screening form of the GRASS r.sun / Fu & Rich approach; NREL PVWatts is the next step for a site-specific estimate.
| Day | Mean direct sun | Possible daylight |
|---|---|---|
| Winter solstice | 8.2 h | 9.6 h |
| Equinox (spring and fall) | 10.2 h | 12 h |
| Summer solstice | 11.9 h | 14.4 h |
| Sunniest candidate pad, winter solstice | 9.5 h | — |
| Canopy over candidate area 1 | 89% | — |
Screening assumptions and per-kW estimate A clear-sky screening ceiling for comparing ground, not a production forecast — assumptions: NREL PVWatts loss factor 0.86, clear-sky irradiance 846 W/m². Indicative estimate: on the order of 1,600 kWh per year for each 1 kW of panels on open ground here.
AccessGrades — measured along the route itself, not across the hillside it crosses; a corridor can hold its stated grade over much steeper ground.
Corridors — a workable line exists; not what building one would involve. Stream crossings are counted where a corridor meets a mapped or modeled watercourse — permitted work.
Existing features — found where measured slope is markedly gentler than the surrounding hillside; detection is fragmentary under canopy, and surface, condition and legal access are not determined.
9 of 9 candidate pad area(s) can be reached by a route holding 25% or less. Where more than one way onto the parcel exists, each is shown separately — which entrance is the practical one is often knowledge the ground holds and elevation data does not.

WaterStreams — published mapping as published by the USGS; modeled drainage is calculated from elevation and shows where water concentrates, not a mapped stream or a flood or wetland finding. Published mapping omits small seasonal draws, which is why both appear. Setbacks are screening geometry only.
Wells — a record of reported wells, quoted as published; not a groundwater measurement or an indication of what a new well would find. Most private wells were never reported, so nearby wells are undercounted; the county health department and local drillers hold the fuller record.

Wells on record
No groundwater well is on record with the USGS within 1 mile(s) of the study area. An empty record is not absence of wells or of water — most private wells predate reporting and never enter this inventory.
- 15.64 acres fall inside the 50 ft setback applied to watercourses and are held out of the pad search.
- 3 mapped wetland feature(s) intersect the study area. Confirm with a wetland professional before disturbing ground.
Water in the landscapeBasis — candidate areas read from measured slope and modeled drainage in the keyline (Yeomans) and permaculture water-harvesting traditions: slow it, spread it, sink it. A swale is a level channel on contour that soaks runoff in; a keypoint is where a draw turns from steep to gentle, and the keyline is the contour through it.
Estimated cut — order-of-magnitude, assuming a modest hand-buildable cross-section, roughly knee-deep and a stride wide.
Rain on catchment — published climatology times measured area; rainfall, not streamflow — part of it evaporates and soaks in before any channel.
Micro-hydro — average-flow potential of the strongest draw; a system needs measured flow through the seasons, an intake the terrain allows, and possibly a water-rights check.
Screening only — nothing here is a construction specification, a hydrologic study, or a statement that a structure will hold water.

Mapping scale and limitsCompiled from aerial imagery at survey scale: mapped positions are approximate and may sit offset from current imagery, and neither a mapped feature nor its absence is a finding about this ground. Forested wetlands under closed canopy are what this mapping most often misses.
Landslide
No mapped landslide feature intersects this study area, and none is mapped within 1 mile of it.

What to ask next
| Licensed Soil Scientist | USDA rates every rated map unit here ‘Very limited’ for septic tank absorption fields, naming slope; slow water movement; depth to bedrock, Ask which candidate areas can be evaluated on the ground. Only this professional may evaluate the parcel for a septic system. |
| Excavation contractor | Area 1 carries an order-of-magnitude range of 1,770–3,287 cubic yards. Ask what that implies for machine access, haul and rock, and whether cut and fill can balance on site. The NW road route already follows existing grading for 72% of its length — ask what re-using that grading would take, versus cutting new. |
| Licensed engineer | The strongest candidate area averages 19% slope — a moderate cross-slope. Ask about foundation approach at that grade, cut and fill batter, retaining structures, and stormwater. |
| Licensed geologist or geotechnical engineer | No landslide feature is mapped here — and absence is not a finding. On ground averaging 40.6% slope, ask whether the inventory covers this county and what the measured slopes call for. This report evaluates none of it. |
| Surveyor | Published (77.19 ac) and measured (77.18 ac) acreage agree closely, but both rest on the same approximate GIS boundary — ask for a survey before money depends on where a line runs. |
| Wetland professional | 3 mapped wetland feature(s) intersect this study area — the Hazards section shows where. Ask whether an on-the-ground determination is warranted; disturbance is regulated by the U.S. Army Corps of Engineers. |
| Well driller or hydrogeologist | No groundwater well is on record with the USGS within 1 mile(s) of this study area — and an empty record is not absence of wells or of water; most private wells never enter it. Ask who has drilled nearby and what they found. |
| Title professional | About 3,758 ft of existing roads and trails cross this study area — whose are they, and may you use them? Right of access is a title question elevation data cannot answer. The strongest access options enter along an existing road — confirming the right to use it comes first. |
| NRCS district conservationist or earthworks contractor | Walk the candidate swale lines and pond areas in the water section with the county's NRCS district conservationist before moving any dirt — conservation practice standards, cost-share programs, and the permits a pond needs all start there. |

Slope is calculated from bare-earth elevation using Horn’s method and reported as rise over run. Elevation is a terrain model, not a surface model: it describes the ground, not vegetation or structures. Class boundaries are indicative starting values, not locally calibrated. Published datasets are displayed as published, without modification. Approximate boundary from public GIS — not a survey.
Notes and limitations
- Approximate boundary from public GIS — not a survey. Parcel geometry is approximate public GIS and has not been located on the ground. Elevation is a bare-earth terrain model — the ground, not vegetation or structures — and slope is measured from it as rise over run, reported as a percentage, not degrees.
- Candidate pad areas, candidate corridors and use screens are screening results measured from elevation data against stated thresholds. The thresholds are indicative starting values, not locally calibrated; the results have not been located on the ground and do not establish that anything may be built. Septic permitting, soils, title and local ordinance also decide each use and are not evaluated here. Earthwork ranges are order-of-magnitude planning figures balancing cut against fill, and exclude clearing, rock, access, drainage and retaining structures.
- Solar figures are estimated direct-sun hours from the parcel's slope, aspect and surrounding terrain horizon on representative days; a clear-sky screening ceiling, not a production forecast. Candidate pad areas are drawn at true footprint size and numbered by rank, with existing graded features and drainage excluded from the search. View range classes are terrain-horizon measurements over bare earth; standing timber can screen any line of sight.
- Published datasets — soils, flood, hydrography, wetland and landslide inventories — are displayed as published by their agencies, without modification, and carry those agencies' own vintages and limitations. Neither a mapped feature nor its absence is a finding about this ground; much of the region has never been systematically mapped. Where a septic tank absorption fields interpretation is shown, it is USDA NRCS's own published rating for the soil map unit, reproduced as published; it is not a determination about this parcel and cannot replace a soil and site investigation by a Licensed Soil Scientist.
- Candidate water-management areas — swale segments, pond areas and keypoints — are screening patterns read from measured slope and drainage modeled from elevation, in the tradition of the keyline system and permaculture water harvesting. They are not construction specifications, hydrologic studies, or statements that a structure will hold water. Swale volumes assume a modest hand-buildable cross-section and are order-of-magnitude figures. Pond construction is regulated: impounding a stream generally requires federal permits, most states regulate dams, and USDA NRCS publishes the applicable practice standard. Mapped wetlands and flood zones are excluded from every suggestion. On this parcel, ground that would otherwise qualify overlapped mapped wetland or flood areas and was excluded rather than suggested.
- Existing graded features are found where measured slope is markedly gentler than the surrounding hillside; detection is fragmentary under dense canopy and some benches are natural rather than cut, so the total is a floor rather than an inventory. Trail grades are sustained-grade guidance, not a construction specification — legal right of access, surface condition and maintenance cannot be established from elevation data.
- This report is informational screening only: it aggregates and visualizes publicly available data. It is NOT a soil evaluation, geologic assessment, land survey, or engineering design, and must not be relied upon as such. Nor is it a geotechnical investigation or a soil suitability determination.
- Consult appropriately licensed professionals before making development or purchase decisions. A soil and site evaluation by a Licensed Soil Scientist is required to determine septic feasibility. This report does not evaluate it. Published landslide mapping records past events and deposits. Interpreting what any of it means for building on this land is the work of a licensed geologist or geotechnical engineer. This report does not evaluate it.
