As land for new housing becomes scarce, developers and local governments seek to expand the housing envelope by pushing closer to existing industrial, mining, rail, and other nonresidential uses. This results in major battles over development approvals and the frequent defeat of housing proposals. Housing that does get approved frequently results in later conflicts between the new residents and the existing users. The collaborative use of simple easements can allow new housing developments to be approved, existing uses to be protected, and written rules of future engagement to be established. This use of Collaborative Land Use Easements (CLUEs) is described in an article in the Winter 2019 issue of Urban Land magazine.
