Site Layout Plan — sheet 14 of the Rankin Estates preliminary plan set, 11/19/2025 (DiPrete Engineering)

Rankin Estates — the proposal, visualized in 3D

Rankin Estates: see what's proposed — on the real land, in 3D

A 126-lot subdivision, "Rankin Estates," is proposed on ≈277 wooded acres off Route 7 (Douglas Pike) in North Smithfield — the woods bordered by the Leonard Drive, Franconia Drive, Indigo Farm Road, Rankin Path, Brookside Drive, Christina Way and Toni Circle neighborhoods.

This viewer was prepared by area residents so neighbors can see for themselves — on real terrain, at true scale — what the developer's plans on file with the Town describe, as we read them: hillsides cut down as much as 61 feet, house pads set on up to 38 feet of stacked fill, roughly 400,000 cubic yards of earth trucked out through a single Route 7 entrance (the applicant's own figures), recreation fields on a raised platform beside Rankin Brook — and how close all of it sits to existing homes.

The source layers are not ours — the plan sheet is the developer's own filing, the terrain is U.S. Geological Survey elevation data, the photo is USGS aerial imagery — but combining them into one 3D picture took interpretation on our part, and we may have made mistakes. Every number is cited to its source document so you can check us, and we correct errors when they're pointed out. Look around and judge for yourself.

Drawn from these specific filings (so you can check us): base map = the applicant's Site Layout Plan (sheet 14 of their 11/19/2025 preliminary plan set) plus their “Recreation Fields Exhibit,” revised 6/30/2026, in the recreation-fields area; road grades and lot pad elevations = the same 11/19/2025 plan set (Plan & Profile sheets 28–40; Grading Plans sheets 15–27 with their Home Grading Tables), whose road profiles are identical in the 11/26/2025 set the applicant submitted to RIDOT; earth-volume figures = applicant counsel's letter of 5/12/2026. Read the originals yourself — the Town posts all Rankin Estates documents here: nsmithfieldri.gov — Rankin Estates documents. The applicant may file newer versions at any time; the Town's page is always the authoritative, up-to-date source.

What the controls do

Lift into 3D — the opening button. The developer's flat plan rises onto the real hills and valleys it would sit on.
Land today / After grading — flip between the land as it is now and the land reshaped as the filed plans describe.
Cut/fill shading — red where hillside would be dug away (deepest: 61 ft), blue where fill would be piled (up to ≈38 ft under house pads).
Fly to… — jump to your neighborhood: Brookside, Indigo Farm, Leonard Drive, Rankin Path, Route 7, Toni Circle — or the deepest cut.
Display — toggle labels, the legend, or 2× height (relief is shown at true scale unless you turn this on).
Technical Filters — measurement layers: click-anywhere depth readout, 5-ft/2-ft contour lines, steep-slope shading, the 200-ft Rankin Brook band, blast-distance rings, a house-for-scale, truck-load arithmetic — each with its source cited.
Sources & disclaimer — what we transcribed from the applicant's filings, what is measured from public data, and what we modeled or interpreted — plus the full legal notice.
Rotate / zoom / pan — drag to rotate, scroll or pinch to zoom, right-drag (or two fingers) to pan. A scale bar sits bottom-left.

For technical readers

Engineers, surveyors, planners and other technical reviewers are invited to test this exhibit: the Technical Filters expose the underlying numbers, and “Sources & disclaimer” documents the method — each figure is cited to the numbered sheet of the applicant's stamped plans, or the public dataset, we took it from. This viewer is our reading of a large record and may contain errors of transcription, registration or interpretation. If you find any inaccuracy, please tell us; it will be reviewed and corrected promptly.

What is transcribed, what is measured, what is modeled

Transcribed — from the developer's own documents: the 2D plan this page opens on is their Site Layout Plan (sheet 14 of the 11/19/2025 preliminary plan set, DiPrete Engineering), reproduced as filed (re-rendered for the web; not redrawn by us). In 3D, the sheet draped on the terrain combines that Site Layout Plan (roads, all 126 lots) with their “Recreation Fields Exhibit” (revised 6/30/2026) in the recreation-fields area; positioning the sheets on the terrain is our georeferencing and can carry small offsets. Road grades and cut depths are our transcription of the tabulated PROPOSED/EXISTING elevation rows on their stamped Plan & Profile sheets (28–40 of the 11/19/2025 set; verified identical in the 11/26/2025 RIDOT set). Deepest road cut: 61.2 ft at Road A STA 67+00 — the red gash on the hilltop. Their counsel's letter of 5/12/2026 concedes ≈750,000 cy must be excavated (“steep slopes and significant valleys which require significant cuts”), with ≈400,000 cy removed from the site, and states the recreation fields were reduced in size to lessen excavation.

The white shape is the development parcel — its boundary comes from the developer's own Site Layout Plan (sheet 14, 11/19/2025), drawn bold; inside it you see their own sheets at print quality (the Site Layout Plan across the subdivision; the Recreation Fields Exhibit west of the brook, where the fields go). Green all around is land the plan does not touch.

Measured — public data: the ground surface everywhere is the USGS 3DEP elevation model (RI statewide LiDAR); registration to the developer's drawing was checked against 13 surveyed contour labels printed on their own exhibit — mean difference 1.6 ft. The surrounding land is USGS aerial imagery (The National Map) so neighbors on Leonard Drive, Franconia Drive, Log Road, Brookside Drive, Christina Way, Toni Circle, Indigo Farm Road, Rankin Path, Mattity Road and Route 7 (Douglas Pike) can find their own homes; white lines are existing streets (US Census TIGER). Note: the “LEONARD DRIVE” text printed on the developer's base map marks an unbuilt paper right-of-way in the woods; the paved Leonard Drive with homes is the street labeled here.

Modeled — reasonable approximation: the graded surface combines three sets of the applicant's own numbers — road profiles (P&P sheets 28–40), the recreation-field pads (exhibit contours, ≈EL 440), and every house lot graded to the garage-slab elevation in the applicant's “Home Grading Tables” (Grading Plans, sheets 15–27; all 126 lots) — with 2:1 transition slopes between pads, roads, and untouched ground. So the broad shaving of hilltops you see across lot clusters (for example ≈15–48 ft of cut on the lots around the Road A loop, and pads filled up to ≈38 ft near the entrance) comes from their own tables, while exact yard-by-yard shaping between pads is interpolated — the applicant's plans may use walkout foundations or retaining walls in those transition zones. Stormwater basins and utilities are not modeled. Vertical datum: elevations are the applicant's; their 1.6-ft mean agreement with USGS LiDAR (NAVD88) confirms a consistent datum. Terrain is true vertical scale unless “2× height” is on.

Technical Filters (off by default): the 200-ft band is measured from the USGS NHD centerline of Rankin Brook — conservative, since RIDEM Rule 250-RICR-150-10-8 §8.10(B) measures from the stream/wetland edge, which extends farther; slope shading is computed from the USGS LiDAR surface; contour lines are generated in the browser from the page’s own USGS 3DEP LiDAR grid (NAVD88, ≈11-ft posting) at a 5-ft or 2-ft interval and re-drawn for whichever surface is displayed — because they come from the very grid being rendered, they always agree with the terrain and the depth probe, but they are slightly generalized versus the surveyed 2-ft contours on the applicant’s grading sheets; the same statewide lidar underlies the State’s published 2-ft contour dataset (RIGIS), against which this layer can be independently compared; note the 10-ft contours visible in the fields-exhibit area are part of the applicant’s own USGS-topo base map, reproduced as filed; the 500/1,000/2,000-ft rings are reference distances from the deepest cut, not predicted impact zones — the applicant's 6/19/2026 memo states blasting “may be necessary,” and until a blast plan is filed the reach of vibration, noise or dust cannot be calculated; the house is a schematic 28-ft two-story for scale only; truck-load arithmetic divides the applicant's 400,000 cy figure by a typical 12–15 cy tri-axle load.

Disclaimer

This page is an independent, illustrative exhibit prepared by area residents from public records, for public education and comment in the pending Town of North Smithfield land-use proceeding concerning the Rankin Estates proposal — a matter of public concern. It was not prepared by, and is not affiliated with, endorsed by, or approved by, the applicant, its owners, its engineers, or the Town; company and firm names appear for identification only. This is not the applicant's plan: the applicant's official filings on record with the Town are the sole authoritative version of the proposal, and nothing here amends or substitutes for them. This visualization is not a survey, engineering, or design document and must not be used for boundary, construction, valuation, or other legal, engineering, or regulatory purposes.

Quantitative figures shown (road-profile elevations, cut depths, excavation volumes) are transcribed directly from the cited public filings. Graphical elements — colors, shading, modeled side slopes and pad elevations, label placement, street alignments from federal datasets, and the terrain rendering itself — are the preparers' good-faith illustration and commentary based on those records and on public federal data, involve the approximations stated above, and may contain errors. Everything reflects documents available as of July 9, 2026; the applicant may revise its plans at any time, and later filings supersede what is shown here. No warranty of accuracy or completeness is made.

Corrections are welcome: if the applicant, its engineers, or any reader identifies an inaccuracy, please write to concerned.residents.ns@gmail.com and it will be reviewed and promptly corrected. The applicant's filings are available from the Town at nsmithfieldri.gov/DocumentCenter/Index/229.
