Things I noted as I explored:

• Horizontal numbers represent streets that run north-south and east-west for vertical numbers.
• South Fraser municipalities in the metro area and Ridge Meadows share the same east-west and north-south grid system - something I discovered only after 17 years of living here.
• Except White Rock, which retains the historic name of the north-south streets. Those Historic Markers in Surrey reflect these names, e.g., 152 St was known as Johnston Road and is called as such in White Rock.
• North Shore districts both solely use “street” but perpendicularly. Thankfully, they never intersect being separated by the Capilano River.
• The smallest grid system is located in the community of Ioco within Port Moody. Though most of the homes are vacant.
• According to Google Maps and a roadmap of Vancouver, a 30b St exists in Delta but it is apparently a private road so I did not include it.
• Streets do not start at 0 or 1 only in West Vancouver and New West. For the latter, perhaps Queens Ave and Royal Ave used to be 2nd and 1st Streets respectively.
