BECI 765-kV Residential & Economic Impact Explorer

Uses the 78 developer-published BECI study segments supplied in the August 2026 GIS package and Wisconsin's live V12 statewide parcel service. Study segments are alternatives, not an approved final route.
How to use this map
Zoom to level 12 or closer. Residential parcels from Wisconsin's official parcel database will appear. Click a parcel for current assessed/fair-market value, taxes, distance screening, and illustrative value-loss scenarios.

Financial scenarios

Published studies do not support one universal loss percentage. This tool therefore uses transparent scenarios rather than claiming a guaranteed reduction.
Low scenario1%
Middle scenario5%
High scenario10%
A 2024 Texas transmission study reported average losses up to about 10% for properties within 0.5 km that were near, but not crossed by, the line. Other studies report smaller, mixed, or statistically insignificant effects. Treat these values as illustrative exposure, not appraisal conclusions.

What this means for local government

A reduction in residential market value can reduce a municipality's equalized property value over time. That does not mean a town automatically loses the same percentage of its tax revenue: levies and tax rates can adjust, shifting part of the burden among taxpayers. Wisconsin electric utility property is generally exempt from ordinary local property tax and subject to the state's utility-tax/public-utility-aid system. DOR's utility-aid formula identifies substations and certain other utility property as qualifying property; a transmission corridor alone should not be assumed to generate equivalent local aid.

Who represents an affected parcel?

The parcel popup identifies its municipality and county. Use these official Wisconsin resources to identify the officials responsible for local tax policy, land-use response and state representation:

Potential endangered / protected wildlife

Wildlife layer added: August 16, 2026. This is a screening overlay, not a field survey and not an assertion that a listed species is present at any specific parcel. Wisconsin DNR intentionally restricts precise Natural Heritage Inventory occurrence data for sensitive species.
Northern long-eared bat
Myotis septentrionalis
Federal status: Endangered. Potential concern anywhere route alternatives cross mature forest, wooded riparian corridors, caves/mines or summer roost habitat.Route-wide
Rusty patched bumble bee
Bombus affinis
Federal status: Endangered. Potential concern where route alternatives cross suitable flowering habitat, prairie/grassland, woodland edges or a USFWS High Potential Zone. The exact HPZ polygons are not reproduced here.Route-wide screen
Higgins' eye pearlymussel
Lampsilis higginsii
Federal status: Endangered. USFWS publicly documents its range in the Wisconsin River and lower Rock River. Generalized regional markers are shown near the Columbia/Portage Wisconsin River area and Rock County; they are not occurrence points.River systems
Monarch butterfly
Danaus plexippus
Federal status: Proposed Threatened as of August 2026. Potential concern wherever milkweed, prairie, grassland and migratory habitat occur along the corridor.Route-wide
Tricolored bat
Perimyotis subflavus
Federal status: Proposed Endangered. Potential concern around caves/mines, forest edges and riparian habitat. Included as an at-risk screening species, not as a confirmed occurrence.Regional screen
Bald eagle
Haliaeetus leucocephalus
Not currently ESA-listed, but federally protected. Wisconsin DNR removed bald-eagle nest locations from its public NHI portal in May 2026, so exact nest points are intentionally not mapped here.Protected
Map symbols: purple dashed route = forest/bat screening; green dotted route = pollinator screening; blue wildlife markers = generalized aquatic concern areas. Turn these layers on/off using the map layer control.

Environmental & habitat layers

Added August 16, 2026. Turn these layers on/off from the map control. They are screening tools for identifying places where a study segment overlaps higher-value habitat or regulated natural resources; they do not replace field delineation, endangered-resources review, or permit decisions.
Wisconsin Wetland Inventory
Official DNR mapped wetlands. Useful for screening wetland crossings and nearby wetland complexes. Actual jurisdictional wetland boundaries may require field delineation.WDNR
Rivers, streams & lakes
Wisconsin DNR 1:24,000 hydrography showing perennial/intermittent streams and open water.WDNR
Trout streams
DNR Class I, II and III trout waters. These often indicate high-quality cold-water habitat and can increase permitting/environmental sensitivity.WDNR
Areas of Special Natural Resources Interest (ASNRI)
Includes designated trout waters, outstanding/exceptional waters, wild/scenic waters, certain State Natural Areas and other specially protected water resources.WDNR
State Natural Areas
Public State Natural Area parcels from Wisconsin DNR. Sensitive internal acquisition/project boundaries are intentionally not shown.WDNR
DNR-managed lands
DNR-owned land, conservation easements and leased managed property. Use DNR's own maps for final ownership/access verification.WDNR
Other public/conservation lands
County forests, Board of Commissioners of Public Lands, U.S. Fish & Wildlife Service, National Park Service, U.S. Forest Service and conservation-reserve lands.Public lands
Annual NLCD land cover
National land-cover imagery for identifying broad forest, grassland/pasture, wetland, agricultural and developed cover. Use it as habitat context, not as a regulatory boundary.USGS / Esri
Best use: turn on one or two environmental layers at a time, then compare them with the blue BECI study segments and residential/economic layers. Segments that overlap multiple resources deserve closer environmental review.

2050 Comprehensive Land Use Plan — Environmental Corridors

Walworth County / southeastern Wisconsin planning context. The official Walworth County 2050 Comprehensive Land Use Plan GIS identifies Primary Environmental Corridors (PEC), Secondary Environmental Corridors (SEC), and Isolated Natural Resource Areas (INRA). These designations are especially useful when comparing BECI study alternatives around Elkhorn, Sugar Creek, and the surrounding Walworth County area.
PEC — Primary Environmental Corridor
Large concentrations of important natural resources. SEWRPC generally defines PECs as at least 400 acres, at least 2 miles long, and at least 200 feet wide. VISION 2050 recommends preserving them in essentially natural/open use and limiting development primarily to essential transportation/utility facilities and compatible uses.Dark green
SEC — Secondary Environmental Corridor
Smaller but significant concentrations of natural resources, generally at least 100 acres and 1 mile long unless connecting primary corridors. VISION 2050 recommends considering preservation as natural/open space, drainageways, parks, or recreation corridors.Light green
INRA — Isolated Natural Resource Area
Important natural-resource concentrations generally at least 5 acres and 200 feet wide that do not meet the size/length criteria for PEC or SEC. These areas are also recommended for consideration for preservation.Pale green
Two map layers are provided:
1. 2050 Comp Land Use Plan — full: displays all official Walworth County 2050 land-use categories using the county's own symbology.
2. 2050 PEC / SEC / INRA only: filters the same official dataset to just the environmental-resource categories for easier comparison with the proposed transmission routes.
Important: these are planning/resource designations, not automatically equivalent to a prohibition on utility construction. However, SEWRPC's VISION 2050 specifically recommends preservation of environmental corridors, and local zoning/land-use decisions may implement additional protections.

County comprehensive-plan & environmental-corridor layers

Route-wide planning review. The developer's current BECI study area spans nine Wisconsin counties: Crawford, Richland, Sauk, Columbia, Dodge, Dane, Jefferson, Rock and Walworth. County planning systems are not standardized, so this map uses each county's closest official GIS equivalent where a public live map service is available. Existing statewide wetland, water, public-land and habitat layers remain available for counties without a comparable live planning service.
Walworth
Official 2050 Comprehensive Land Use Plan. Dedicated PEC, SEC and INRA layer already included.LIVE GIS
Jefferson
Official Environmental Corridor layer from the County Agricultural Preservation/Land Use planning system. Includes wetlands, floodplain, public lands, upland woods, steep slopes and surface-water resources.LIVE GIS
Columbia
Official Environmental Corridors (PZD) layer. County plan defines corridors using floodplain, wetlands, water buffers, public open space, slopes, shallow soils and large woodlots.LIVE GIS
Dodge
Official Future Land Use layer from Dodge County Land Resources & Parks. The adopted 2045 plan includes a Conservancy Overlay among its future-land-use categories.LIVE GIS
Sauk
County comprehensive-plan update is underway. Until a new future-plan GIS layer is published, the map includes official Protected Area Boundaries and Protected Easements as the strongest currently published county conservation-planning layers.LIVE GIS
Dane
Dane County's Comprehensive Plan includes Environmental & Open Space Corridors, Environmentally Sensitive Lands, parks/open space, habitat, wetlands and planned land use. I found the official plan maps but not a stable public ArcGIS REST layer suitable for direct embedding.PLAN LINK
Richland
County uses its Comprehensive Plan Future Land Use Map for growth-management decisions. A 2024 county future-land-use map is available, but no stable public plan MapServer was located for direct overlay.PLAN LINK
Rock
Current countywide Comprehensive Plan 2035 remains published while Renew Rock 2025–2045 is being prepared. The new Farmland Preservation Plan was adopted in August 2026. No equivalent live environmental-corridor MapServer was located.PLAN LINK
Crawford
County and local comprehensive/farmland plans emphasize agricultural, forest and natural-resource preservation, but I did not locate a countywide live future-land-use/environmental-corridor service that can be reliably embedded.PLAN / STATE GIS
Important: “PEC / SEC / INRA” terminology is specific to the southeastern Wisconsin/SEWRPC planning framework. Other counties protect similar resources under names such as Environmental Corridor, Conservancy Overlay, Environmentally Sensitive Lands, Protected Areas, open space, farmland preservation, wetlands and floodplain. These layers are planning evidence; they do not by themselves establish that transmission construction is prohibited.
