General

Suitability

4.01

No subdivision shall be approved

unless it is suited to the configuration of the land being

subdivided;

unless it is suited to the use to which it is intended;

if it makes impracticable the further subdivision of any land within the

proposed subdivision or of any adjacent parcel;

if it does not comply with these regulations.

Other regulations

4.02

Nothing contained in these regulations shall relieve the owner of a subdivision from the responsibility to seek out and comply with the legislation applicable to that owner's undertaking.

[am. B.C. Reg. 45/2022, Sch. 3, s. 2.]

Intended use

4.03

The owner of any land being subdivided may be required to state in writing the

intended use of any parcel being created or of any remaining portion of the land being

subdivided.

Characteristics not approvable

4.04

Without limiting the generality of

section 4.01, approval of any

subdivision may be refused if it

contains

land which is subject to erosion, or

a parcel which is divided by land subject to erosion into areas not suited to

the use to which it is intended,

contains land which

may slip when developed, used or occupied,

when developed, used or occupied may cause land on an adjacent parcel to slip,

iii

may be inundated by a land slip if land above on another parcel

slips,

contains land which is subject to flooding so as to render it unsuitable for the

use to which it is intended, or

contains land which because of inadequate drainage is not suitable for the use

to which it is intended.

Covenant

4.05

Notwithstanding the requirements of

section 4.04, the subdivision of

land which is subject to any of the conditions described in

section 4.04 may be approved,

provided that the owner agrees in writing to registering a condition or covenant pursuant

section 219 of the Land Title Act in favour of the Crown

at the time of subdivision. Such condition or covenant shall be satisfactory to the

approving officer and shall restrict or prohibit the construction of buildings or

structures on, and (or) the use of any parcel or part of such parcel which is subject to

any of the conditions described in

section 4.04.

Information required

4.06

In order that any proposed subdivision may be properly considered by the approving

officer, the owner of any land being subdivided may be required to provide any of the

following:

topographic survey where the terrain is steep, irregular or otherwise difficult

to appraise in respect of the subdivision suiting the configuration of the land being

subdivided;

spot elevations;

a professional engineer's report on

the effect on soil stability of disturbing natural grades or natural growth,

or changing the moisture content of the soil by developing, using or occupying the

The design of any community water system to serve the subdivision shall be in

accordance with the requirements of any authority having jurisdiction over the system

pursuant to

the Health Act and the Water

Utility Act ,

the Health Act and the Water

Act , when an improvement district has an applicable

subdivision bylaw pursuant to the Water

Act , or

the Health Act and the Municipal Act , when a regional district has an

community water system,

as the case may be.

The community water system approved pursuant to

section 4.09 (1) shall be

installed as approved before the subdivision is approved.

Notwithstanding the requirements of

section 4.09 (2), a subdivision

may be approved prior to the construction of the community water system, provided that

an arrangement securing performance of such construction satisfactory to the approving

officer has been made with

the Comptroller of Water Rights (under the Water Utility

Act ),

an improvement district having an applicable subdivision bylaw adopted

pursuant to the Water Act , or

a regional district having an applicable bylaw setting out the terms and

conditions of any extension to its community water system,

as the case may be, but in no case shall the subdivision be approved before the

plans for the community water system have been approved.

Community sewer system

4.10

The design of any community sewer system to serve the subdivision shall be in

accordance with the requirement of any authority having jurisdiction over the system

pursuant to the Health Act and the Waste Management Act , and where applicable in

accordance with either

the Water Act , when an improvement

district has an applicable subdivision bylaw pursuant to the Water

Act , or

the Municipal Act , when a regional

Notwithstanding the requirements of subsection (1), where a subdivision is

pursuant to

section

4 of B.C. Reg. 199/70 5 , and where local

snow and terrain conditions, as determined by the approving officer, preclude year-round

vehicular access to any parcel, the parcel, pursuant to

section 4 (

or to local conditions, or

where a highway is a lane, when it shall have a minimum width of 20

feet.

Lanes

5.03

Lanes shall be provided where terrain and natural features render vehicular access

practicable and where

they form an extension of any existing system of lanes, or

the approving officer deems it necessary to provide secondary access in order

that reasonable traffic flow can be assured on the main highway.

Access to highways

5.04

Roads shall be provided to give access to parcels adjoining controlled access

highways unless the minister responsible for the Transportation

section 51 of the Transportation

Act , to authorize the creation of such access.

[am. B.C. Reg. 555/2004, s. 3.]

Intersecting highways

5.05

Subject to the Transportation Act and to the Land

Title Act , where any subdivision contains parcels less than 300

feet in width, intersecting highways shall be dedicated at intervals not greater than

1 320 feet and on the same side of the highway and beginning at any existing lateral

highway, except

where the parcel being created is pursuant to

section 6.11,

where difficult terrain or other natural features render vehicle access

impracticable, or

where the pattern of existing subdivision precludes the necessity of providing

access.

[am. B.C. Reg. 555/2004, s. 4.]

shall be large enough to contain a circle with a radius of 50 feet.

Intersections

5.08

The number of highway intersections within a subdivision shall be kept to a

minimum, and, where practicable,

Y-shaped intersections shall be avoided;

T-shaped intersections shall be used when the intersecting highway is to carry a

small amount of local traffic;

intersections with more than 4 legs shall be avoided;

intersections shall not be located in or near sharp curves or near the crest of

any rise or hill.

and

where both building and zoning regulations are in force, that parcel shall not

be smaller than 5 000 square feet, except that a parcel may be decreased in area by as

much as 10%, provided that the approving officer is satisfied with the validity of the

owner's written claim that, because of unusual terrain or the size or the configuration

of that owner's land, 5 000 square foot parcels cannot be achieved and therefore subdivision is

precluded, but as many parcels as the approving officer considers practicable shall be

not smaller than 5 000 square feet,

where both building and zoning regulations are in force, and where a lane

provides secondary access to that parcel, there shall be no minimum parcel size,

and

where building or zoning regulations pursuant to the Municipal

Act are not in force, that parcel shall not be smaller than

6 000 square feet.

[am. B.C. Reg. 45/2022, Sch. 3, s. 2.]

case may be, where a parcel is served by a community water system but not a community

sewer system, that parcel shall not be smaller than 7 500 square feet, except that a

parcel may be decreased in area by as much as 10%, provided that the approving officer is

satisfied with the validity of the owner's written claim that, because of unusual terrain

or the size or the configuration of that owner's land, 7 500 square foot lots cannot be achieved

and therefore subdivision is precluded, and that at the decreased size all requirements of

section 6.04 can be met, but as many parcels as the approving officer considers

practicable shall not be smaller than 7 500 square feet.

[am. B.C. Reg. 45/2022, Sch. 3, s. 2.]

part of these regulations, or

where the requirements of paragraph (

a) cannot be met, consideration shall be

given to alternate designs which will dispose of the liquid in the minimum size septic

tank for a 3 bedroom, single family house, and which designs are in accordance with the

requirement for alternate methods of disposal contained in the Regulations Governing

Sewage Disposal and for which acceptable alternate designs and adequate area of

appropriate soil is available for disposal, and the parcel shall be sized accordingly,

except that where, in extraordinary and infrequent instances, the owner of the parcel

accordance with the foregoing, the subdivision may be approved, provided that the owner

agrees in writing to registering a condition or covenant pursuant to

section 219 of the

Land Title Act in favour of the Crown at the time the

subdivision is registered; such condition or covenant shall be satisfactory to the

approving officer and shall restrict or prohibit the construction of buildings or

structures on and (or) the use of any parcel until the necessary installations have been

made, and

copies of the results of all tests shall contain the signature, occupation and

permanent address of the person undertaking the tests and shall accompany the plans of the

proposed subdivision when it is submitted to the authority having jurisdiction to receive

subdivision applications.

Design of larger disposal system

6.05

Except where the Waste Management Act is applicable,

where a parcel is less than 5 acres and is not served by a community sewer system and

where the intended use has a greater design sewage flow per day than the minimum capacity

septic tank for a 3 bedroom, single family house in accordance with the Regulations

Governing Sewage Disposal, the design sewage flow of the intended use shall be used in

accordance with the Regulations Governing Sewage Disposal to determine the area of soil

required in

section 6.04 (

a) and all other requirements of

section 6.04 shall be

met.

Test results

6.06

Where any parcel in a proposed subdivision is less than 5 acres and is not served

by a community sewer system, a copy of the plans and test results and measurements

required in Appendix B as applicable to that parcel shall be submitted by the approving

officer to the medical health officer or to the Regional Waste Manager, Ministry of

Environment, as the case may be, for written reasons why the medical health officer or the Regional Waste Manager would or would not recommend

approval of a subdivision based on the waste disposal capabilities of the soil on that

parcel to meet with the requirements of these regulations or of the Waste

Management Act , as the case may be.

[am. B.C. Reg. 45/2022, Sch. 3, s. 3.]

Old subdivisions

6.07

When the percolation rate is 30 minutes or more, see

section 6.04

(

b) of the Subdivision Regulations. Percolation tests shall be

carried out in accordance with

section 6 below.

Depending on the slope measured from the uppermost point on the parcel to the

lowest point on the parcel, the results obtained in

section 1 above shall be increased in

accordance with the following:

Steepest slope (per cent)

Minimum area to be added to parcel (sq. ft.)

Less than 10

For each 5% or part thereof for 10% and over

Regardless of the smallest parcel size permitted in accordance with sections

1 and

2 above, the

parcel shall contain an area of soil suitable for sewage disposal not smaller than the

following, as determined by the percolation rate:

Percolation rate (min./inch)

Minimum size of area of soil (sq. ft.)

Less than 5

1 000

5 and more, but less than 10

1 500

10 and more, but less than 15

2 000

2 500

20 and more, but less than 25

3 000

25 and more, but less than 30

3 500

There shall be a minimum of 4 feet of natural porous topsoil above the

groundwater table in the area of soil referred to in

section 3 above, and a representative

number of testholes shall be dug in that area to a minimum depth of 4 feet to demonstrate

this.

The area of soil required for sewage disposal in

section 3 above shall be capable of meeting

the siting requirements for absorption fields in the Regulations Governing Sewage

Disposal.

Percolation tests shall be undertaken, as follows:

Percolation test holes shall be made at points and elevations selected as

typical in the area of the proposed disposal field.

One of these test holes shall be dug at each end of the area of the disposal

field. Further holes may be required, depending on the nature of the ground and the results

of the first test and the size of the proposed field.

Test holes are usually drilled using an auger and to the depth of the

proposed absorption trench. The standard depth is 24 inches, but the Public Health Inspector

may approve or require holes varying from 18 to 32 inches in depth.

The soil should be examined as it is removed from the test hole for some

indication of its composition and likely percolation rate.

To make the percolation test more accurate, any smeared soil should be

removed from the walls of the test hole.

If the soil contains considerable amounts of silt and (or) clay, the test

hole should be presoaked before proceeding with the test. To do this, keep the hole as fully

filled with water as possible for 4 hours. Proceed with the test immediately after

presoaking.

To undertake the test, fill the test hole with water. When the water level is

5 inches or less from the bottom of the hole, refill the hole to a depth of 24 inches or to

the top. No recording of time need be done for these 2 fillings.

When the water level after the second filling (step (g)) is 5 inches or less

from the bottom of the hole, add enough water to bring the depth of water to 6 inches or

more.

Observe the water level until it drops to the 6 inch depth. At precisely 6

inches, commence timing. When the water level reaches precisely 5 inches depth, stop

timing.

The time in minutes for the water level to drop 1 inch is the percolation

rate for that hole and is recorded in minutes per inch. The percolation rate of the

absorption field is the average rate of all the percolation tests made for that

field.

Backfill the holes with the excavated soil and repeat the test in other

locations. Record the results and submit to the local authorities.

See

section 4.07 of the Subdivision Regulations.

NOTE ON

SECTION 6 — A percolation test is used to measure the permeability of the

soil at the depth of the proposed drainage field. The percolation test will determine the

rate, which is a measure of the time in minutes for the water level in a hole to drop 1

inch (from 6 inches from the bottom to 5 inches from the bottom of the hole) and is

recorded in minutes per inch .
