Check this out! The Beacon Hill Neighborhood of Seattle is planning a Food Forest. I will definitely be following the progress of this project. I hope this sets a precedent for Seattle and Vancouver neighborhoods to follow in their footsteps. From their site:
"A Food Forest is a gardening technique or land management system that mimics a woodland ecosystem but substitutes in edible trees, shrubs, perennials and annuals. Fruit and nut trees are the upper level, while below are berry shrubs, edible perennials and annuals. Companions or beneficial plants are included to attract insects for natural pest management while some plants are soil amenders providing nitrogen and mulch. Together they create relationships to form a forest garden ecosystem able to produce high yields of food with less maintenance."
