In trend of increasing of urban park renovation projects, the role of official documents which includes various information about purpose of the park or policy of the plan has becoming important for planning of renovation project. But, in local governments many documents about original plan of parks have been disposed under ‘Official document control system’. In this situation, we researched about preserving conditions of official documents relating to park planning and design, and consciousness of the person in charge about park planning. As the result, we got following conclusions. In most cities, many official documents are disposed after the end of five years preservation term, but some documents are remaining unofficially. Staffs of local governments have concerns about this situation and have expectation to theses unofficial documents and formal documents under legal system, such as ‘Urban parks ledger’, ‘Urban planning document’ for preserving information in these documents. But what system is effective and feasible will be an issue to be resolved.
