Blasting & Rock Breaking Application Guidelines

The District requires a permit for any type of rock breaking including blasting and rock splitting. These guidelines are intended to clarify the requirements in order to obtain these permits, however where there is a discrepancy with the actual bylaw, the bylaw shall prevail.

Exemptions

  • Permit may be exempt for quantities less than 10 m³, at the discretion of Land Development Engineering
  • Permit is not required for emergency works
Procedures for Blasting

Blaster/applicant submits complete blasting permit application to Land Development Engineering.

Complete application includes:

  1. Valid Blasting Certification issued by WCB
  2. Schedule C indemnification completed by Owner
  3. $5,000,000 certificate of insurance
  4. Application fees
  5. Blasting application fee is $1,000
  6. Refundable damage deposit for blasting is $2,500
  7. A pre-blast topographic survey showing the extent of rock to be blasted.  Do not include any overburden materials in the pre-blast volume calculation.  Maximum allowable quantities are 1.5 m times the area in square metres of the principal building and garage footprint or 600 m³, whichever is less.  Quantities shall be calculated as 900 mm (3 ft) beyond the exterior wall (also interior walls if the house is terraced), plus 400 mm (14”) below the top of a slab.
  8. Report on noise muffling, where required
  9. Letter of Assurance completed by Owner and Consulting Engineer
  10. Control Measures Blasting Plan accepted by Consulting Engineer
  11. Pre-blast condition inspection of affected properties as determined by the Consulting Engineer (minimum 50 m radius), and a plan showing the affected properties

Land Development Engineering approves Blasting Permit upon confirmation a building permit has been issued, except where otherwise provided.

At least 48 hours notice to neighbours within 120 metres shall be given of the commencement of any blasting, and at least one week’s notice shall be given of any blasting expected to continue for more than two days. (This notification also applies for extensions of blasting permit).

Consulting Engineer monitors blast, including ground vibration measurements.

One extension allowed per permit, providing an adequate reason is given to and accepted by Land Development Engineering.

Upon completion of blasting, the applicant notifies Land Development Engineering and each affected owner, in writing, when the blasting to be carried out under the permit is completed.

Blaster/applicant provides a post-blast topographic survey to verify rock quantities, where proposed rock volume exceeds 90% of allowable or as required by Land Development Engineering. Footings will not be inspected until a post-blast topographic survey has been approved by Land Development Engineering.

Blaster/applicant provides a post-blast condition inspection of affected properties or written sign-off by the property owner.

Land Development Engineering refunds damage deposit when all issues are addressed and completed to the District’s satisfaction.

Procedures for Splitting Rock

The applicant submits complete soil removal and deposit permit application to Land Development Engineering. 

Complete application includes:

  1. Application fees: $250 under 100m3 rock removal; and $500 over 100m3 rock removal.
  2. A topographic survey showing the extent of rock to be split/ broken. Maximum allowable quantities are 1.5 m times the area in square metres of the principal building and garage footprint or 600 m³, whichever is less. Quantities shall be calculated as 900 mm (3 ft) beyond the exterior wall (also interior walls if the house is terraced), plus 400 mm (14”) below the top of the slab.
  3. Control Measures Plan submitted by the Geotechnical Engineer. The plan is to address rock breaking procedures, if there is any risk to neighbouring properties, rock type and general control measures to be taken throughout the rock breaking.

At least 48 hours notice shall be given of the commencement of any rock breaking, and at least one week’s notice shall be given of any rock breaking expected to continue for more than two days.

Upon completion of rock breaking, the applicant notifies Land Development Engineering and each affected owner, in writing, when the rock breaking to be carried out under the permit is completed.

Applicant provides post-rock breaking topographic survey to verify rock quantities, where required by Land Development Engineering. Footings will not be inspected until the post-blast topographic survey has been approved by Land Development Engineer.
