NOTIFICATION OF: “DRILLING AND BLASTING”

RE: City Gate project at McCallum Rd, Langford, BC

To all homeowners, Residents and Commercial Proprietors,

As part of the construction process the blasting of rock formations for service trenches and footings will continue to commence in your area for approximately 1 year. A Pre-Blast Survey has been conducted by MLP Consulting prior to the blasting that has been happening to record and establish a “present status reference baseline” in the event of future concerns that may arise from the construction process. Each and every blast event will continue to be seismically monitored on Seismographs to ensure the vibration levels on homes within the blast impact perimeter are contained within acceptable industry levels. Blasting will take place Mondays — Thursdays between 8:30 am and 4:00 pm and Fridays between 8:30 am and 3:00 pm, except statutory holidays.

The blast locations will have proper blasting signage at all appropriate locations surrounding the sites. A notice of blasting commencement will be posted in high traffic areas for the benefit of the local residents. Animals are affected by blast vibration and noise, so posting commencement timing allows owners to attend to their pets or any other arrangements they deem fit. The vibration can cause rattling of items inside your home and therefore it is recommended you ensure your pictures/wall hangings and delicate china/crystal are secured. Homes are engineered to withstand vibrations from various sources all comparable to blast and construction vibration.

Prior to each blast event there will be 12 blasts of a horn. That will indicate it will be 2 minutes until the blast event fires. After each blast the contractor will sound a 15 second all clear blast indicating area now safe. Depending on how far you are, you may or may not hear the horn blasts.

Little Rock will stringently adhere to all operational and safety standards and protocols for
Urban Blasting, WorkSafe BC with all appropriate permits, licenses and required documentation
in place. We will conduct blasting operations with the concerns of homeowners at the forefront
to mitigate blast vibration impact on homes within the blast vibration impact perimeter.

If any questions arise regarding blasting related concerns, feel fee to contact me at any time at
the email below with your name, address, and contact information.

Yours Truly,

Chris Conley
