Potential build site — identified from county GIS
A plain-language status — not a score. This page documents 3 facts from public records, estimates 2 more from models, relies on 8 unverified screening defaults, and lists 8 things to verify before you rely on it.
This parcel in Cottage Grove sits in the South Washington County Schools school district. Part of the parcel is mapped in a FEMA Special Flood Hazard Area, so flood insurance and elevation requirements likely apply. Wetland indicators overlap the parcel in screening data — a field delineation is the next step, since mapped lines are not legal boundaries. On utilities, water service is undocumented and sewer service is inside the regional service area — a connection is not confirmed until the city or utility confirms it, so budget time to verify location and fees. We do not yet have data on terrain, water service, and tree canopy — on this page, unknown never means "no concern."
Rules applied: Regional/state screening defaults (unverified) Some rules shown use a regional screening default — the Cottage Grove ordinance is not yet loaded for them; verify locally before relying on any number.
Recorded, authoritative facts.
Modeled or preliminary — useful for screening, not decisions.
Professional and municipal confirmations before you build.
Written for homeowners; open “the details” on any card for the builder view and the raw measurement behind it.
Slope & terrain: not yet evaluated — unknown is not the same as no concern. no slope statistics
Builder view: Slope & terrain: no qualifying evidence in the current dataset (no slope statistics); treat as unresolved, not as clear.
Part of this parcel is mapped in a FEMA Special Flood Hazard Area (zone floodway); flood insurance and elevation requirements likely apply — confirm with the city and a surveyor.
Builder view: FEMA zone floodway (SFHA) per current NFHL data; floodplain ordinance and base flood elevation requirements apply — elevation certificate and local floodplain review required.
Mapped wetland/public-water indicators overlap this parcel. This is a screening result, not a confirmed legal boundary — a wetland delineation is recommended before design or purchase decisions.
Uses a regional screening default — the local ordinance is not yet loaded. Verify locally.
Builder view: NWI/PWI overlap present — a SCREENING constraint, not a delineated boundary; a wetland delineation is recommended before design or purchase decisions. A 50 ft screening buffer applies (screening default). WCA/LGU review applies if impacts are proposed.
Public utilities may be available nearby; connection location & fees require confirmation
Uses a regional screening default — the local ordinance is not yet loaded. Verify locally.
Builder view: sanitary sewer: inside the regional wastewater service area (MUSA) — membership is a planning designation, NOT a connection at the boundary; timing unknown, confirm staging with the city.
Water service: not yet evaluated — unknown is not the same as no concern. water service not documented
Builder view: Water service: no qualifying evidence in the current dataset (water service not documented); treat as unresolved, not as clear.
This parcel is in the South Washington County Schools school district per current boundary data.
Builder view: School district: South Washington County Schools (MDE boundary data; boundaries can change — verify for enrollment decisions).
Preliminary buildable envelope ≈ 1,641 sq ft (about 1.7% of the lot) — a conservative estimate; the actual buildable area is likely larger once lot edges are classified. Based on regional/state screening default (unverified) — not the local ordinance; verify with the jurisdiction setbacks; confirm your parcel's zoning. Governing setback is the shoreland OHWL standard (150 ft) — regional/state screening default (unverified) — not the local ordinance; verify with the jurisdiction; measured from the mapped water edge (DNR Public Waters Inventory basin delineation, retrieved 2026-08-08) — an approximation, not the surveyed ordinary high water line.

Builder view: Conservative uniform inward buffer at the largest applicable setback (35 ft): ≈ 1,641 sq ft (1.7% of lot). Under-approximates the true asymmetric envelope; edge classification will refine. Resolved setbacks: front 35 ft, side 15 ft, rear 35 ft, corner side 20 ft. Based on regional/state screening default (unverified) — not the local ordinance; verify with the jurisdiction setbacks; confirm your parcel's zoning. Governing setback is the shoreland OHWL standard (150 ft) — regional/state screening default (unverified) — not the local ordinance; verify with the jurisdiction; measured from the mapped water edge (DNR Public Waters Inventory basin delineation, retrieved 2026-08-08) — an approximation, not the surveyed ordinary high water line.
This lot is in a mapped shoreland zone of a General Development-class water: structures must be set back 150 ft from the ordinary high water line (regional screening default). The OHWL location comes from a survey, not a map.
Uses a regional screening default — the local ordinance is not yet loaded. Verify locally.
Builder view: Shoreland zone — DNR class General Development. structures must be set back 150 ft from the ordinary high water line — regional/state screening default (unverified) — not the local ordinance; verify with the jurisdiction. Bluff and shoreland-impervious standards may also apply; OHWL per survey.
Trees & canopy: not yet evaluated — unknown is not the same as no concern. tree-canopy coverage not yet computed
Builder view: Trees & canopy: no qualifying evidence in the current dataset (tree-canopy coverage not yet computed); treat as unresolved, not as clear.
