Rule #1: Safety Matters
Engage a city get them to cut a million dollar check.
Engage the community with campaign to begin to make up the shortfall required to design, construct, and maintain the sidewalk. The check will help with moving power and infrastructure.
Rely on community volunteers to motivate the campaign over and over in a variety of ways, including auctions, wine events, concerts and support them with marketing assets worthy of their efforts.
Oh, the safety concept: triple the width of the sidewalk add separation and narrow the road - traffic will slow.
