Office Parks and Pedestrian Access

One of the issues with office park development is that it has the tenancy to make driving the only practical mode for access. Take the following example of an office park in the Cloverdale area in Surrey:

If I wanted to get to 60th Avenue from this office park, the easiest route would be to follow the green line.

Unfortunately since this is all private property, the two developments didn't coordinate anything, so I have to follow the much longer red line route. It's little thing like this that make walkability difficult in many parts of our region and would be really easy to fix with a little planning...
