Thompson-Nicola, Electoral Area E (Bonaparte Plateau)

In Area E, a zone limited to detached houses must allow at least one secondary suite or detached accessory home (a garden suite or carriage house) next to a house. A floor of 3 or 4 homes applies on rural land only inside an urban containment boundary drawn in a regional growth strategy, and most rural land is outside one. None of it applies on land in an Islands Trust local trust area or under a rural land use bylaw, and in the Agricultural Land Reserve the Commission's limits come first. How many homes you can build on a lot.

The Province's principal residence requirement doesn't apply in Area E (list in force from June 1, 2026), so the provincial rule doesn't limit short-term rentals to the host's home. Local bylaws, including the zone's own rules, can be stricter. Hosts anywhere in BC register each unit with the provincial registry. Short-term rental rules in BC.

Reports for rural lots in Area E name the zone from the Thompson-Nicola Regional District's zoning map.

• TNRD Zoning Bylaw No. 2400, 2012Covers 98% of the area. 29 zones explained, from the bylaw as amended to October 1, 2026, checked October 30, 2026.

Shares of the area's land and water, worked out from the Thompson-Nicola Regional District's zoning map (Open Government Licence – Thompson-Nicola Regional District); a bylaw is listed where at least 20 ha and 1% of it lies here. Lots inside a municipality follow its own bylaw. Confirm with the TNRD's planning department before you buy or build.

Check one lot: look up its address for its zone and the share of the lot in each.

The federal boundaries put 18 reserves of 5 First Nations in or beside Area E. On reserve land the First Nation decides land use, not the local zoning bylaw; a report says when a lot is on reserve land or within 500 m of it. Reserve land in BC, by place.

The Thompson-Nicola Regional District's building inspection covers all of Area E (Building Regulations Bylaw No. 2066, 2005): building, adding on, moving or demolishing a building needs a building permit, and the work is inspected. Our reading of the Thompson-Nicola Regional District's own page, checked 2026-10-07. Do you need a building permit on rural land?

The Province maps one designated community watershed, Clinton Community Watershed, over less than 1% of Area E: land draining to a licensed drinking-water intake, where logging and roads on Crown land must protect the supply. A report says whether a lot lies in one and whose water it is. Community watersheds in BC, by place.

The Province's monitoring records hold groundwater samples from 1 well in Area E, 2000 to 2025, among them 1 of the Province's observation wells. No well's median passed Health Canada's limits for arsenic, fluoride, manganese, uranium, nitrate or lead. A report names the nearest sampled wells within 10 km of a lot. A neighbouring well isn't your water: test your own. What BC's well water tests for, by place.

Mapped aquifers

8 mapped aquifers lie in Area E, most wells first.

1. 1Aquifer 124: Fraser Plateau Lavaflat-lying to gently-dipping volcanic bedrock276 wells · moderate productivity
2. 2Aquifer 133: Cache Creek to Scottie Creekconfined sand and gravel (glacial)48 wells · high productivity

8. 8Aquifer 922: 3 Mile Lake / southeast of Clintonfractured sedimentary rock5 wells · low productivity

An aquifer is listed for each place that holds at least a twentieth of it, so a sliver of one at the edge can be left out. Wells and productivity are for the whole aquifer, which can reach well beyond Area E. The province maps aquifers mostly in settled valleys, so a lot outside every outline can still have groundwater.

A lake is listed for each place that holds at least a twentieth of it or 100 ha of it. Clarity is the median summer Secchi depth; the nutrient class is our reading of Carlson's index from phosphorus or chlorophyll, not a provincial rating. Either is given only for a lake with at least 10 summer readings from open water, spread over at least 3 different years, since 2012. Most lakes have never been sampled, so a lake missing here may simply have no record. Every sampled lake in BC.

Normals for 1981-2010 at the Vidette Lake Sharpe Lake station, about 27 km from the middle of the area's addresses at Green Lake (of the communities here with a station within 30 km, the one with the most addresses); ECCC has no fuller 1991-2020 set for it. * Based on at least 15 of the 30 years, short of the World Meteorological Organization's standard: treat as a rougher guide. The records are single days measured at the station: the most rain, snow and wind it saw in its record up to 2010 (ECCC's 1981-2010 sets give records over the station's whole history, so some dates are older than 1981). Each is one event, not what to expect in a year, and the lot can get more or less than the station. Elevation matters a lot in BC: a hillside lot can be much colder and snowier than the station. We don't set this station's figures against other places: it's more than 15 km from the place.

Plant hardiness zone: most homes here are in zone 4a (78%); 14% are in 3b, on Natural Resources Canada's 2025 map. Higher numbers are milder winters. What the zones mean.

Solar panels: a south-facing panel tilted at the latitude would make about 990 kWh a year for each kW of panels at the middle of the area's addresses at Green Lake, about 36 of it in December (estimated from Natural Resources Canada's 1998-2022 sunshine map). An open sky is assumed: the hills, trees and buildings around a lot cut it, and a report sets the lot's own skyline beside it. What solar panels would make in BC.

By the 2050s (2041-2070) at Green Lake, climate models project about 8 more days over 30 °C a year, a longest frost-free run about 35 days longer and about 6 percentage points less of winter's precipitation falling as snow, each against the same models' 1971-2000 (model projections under SSP2-4.5, a middle path for emissions). The models work on a grid of about 9 by 6 km, which averages valley floors with the slopes around them, so their own figures can sit well off a station's normals and aren't comparable with them. Their own figures there: about 10 days over 30 °C a year in 2041-2070 (range 6 to 23 across the models), against about 2 days in 1971-2000; a longest frost-free run of about 130 days (range 125 to 155), against about 95; and about 86% of winter's precipitation falling as snow (range 78% to 90%), against about 92%. The ranges run from the 10th to the 90th percentile of the models' 2041-2070 figures. The 2050s across BC.

Light at night within 1 km of the middle of the area's addresses at Green Lake: none recorded from space, and darker than about 94% of BC's homes (2024 satellite record). A lot away from the centre can be much darker. How dark are BC's nights?

Lightning: around the middle of the area's addresses at Green Lake, a cloud-to-ground flash within 10 km on about 10 days a year and 0.18 flashes per km² a year, more than at 3 in 4 BC homes (the Canadian Lightning Detection Network, 1998-2025 average, on a grid of about 11 by 7 km).

The BC Energy Regulator maps about 29 km of active oil and gas pipeline in Area E, permitted to 2 companies: FortisBC Energy Inc. and Westcoast Energy GP Inc. Under a kilometre more is on recent permits it lists as new; under a kilometre is abandoned or deactivated, often still in the ground. A report lists any pipeline within 200 m of a lot, and flags one within 30 m, where digging needs the permit holder's agreement. Pipelines in BC, by place.

The Province lists 7 active waste discharge authorizations in Area E; the commonest kinds: sewage treatment or discharge site (2), waste incinerator (2) and mine (1). Of these, 2 may discharge effluent to water or land. A report lists any within 2 km of a lot, and flags one whose point is on it. Permitted discharges in BC, by place.

The Province maps no open gravel pit or quarry in Area E, but 2 open mineral exploration permit areas. A report lists the permits within 2 km of a lot, names an open pit or quarry within 500 m and flags one whose permit area takes in the lot. Gravel pits and mine permits in BC, by place.

On ParcelMap BC, the land in Area E is 5% private, 19% Crown land with a parcel drawn (15% with no title); no parcel is mapped over 76%, likely most of it untitled Crown land, with lakes and road allowances. A report says who owns the land along a lot's line. Crown land next to a property, and every place's land by owner.

The Ministry of Forests maps 83 active Crown range tenures (80 grazing, 3 hay cutting) reaching into Area E, over 85% of its area, licensed for about 96,656 animal unit months of grazing a year in all. Outside a pound district, keeping livestock off a lot is the owner's fence to build. A report lists any tenure within 1 km of a lot. Open range and grazing in BC, by place.

The Province maps 34 registered traplines over 92% of the area and 9 guide outfitter territories over 79% in Area E. The maps are drawn over titled land too, but traplines are registered on Crown land: on titled land, anyone but the owner or occupier needs their written permission to trap. A report says whether either takes in a lot. Traplines and guiding territories in BC, by place.

Area E lies in wildlife management units 3-30 (32%), 3-31 (30%), 5-3 (12%), 3-32 (10%), 5-2 (8%): the Hunting and Trapping Regulations Synopsis sets seasons and closed areas by unit. Hunting and shooting on your own property.

BC Parks maps 19 parks and protected areas (Arrowstone Park, a provincial park; Big Bar Lake Park, a provincial park; Bonaparte Park, a provincial park; Chasm Ecological Reserve; and 15 more) reaching into Area E, over 11% of its land. Recreation Sites and Trails BC lists 21 sites there. A report names the nearest park and recreation site within 25 km of a lot. Parks and recreation sites in BC, by place.
