THE Hong Kong Sports Development Board has given national associations six weeks to outline their cash requirements for the next financial year. SDB staff will discuss individual plans with representatives from the associations, who have to submit their proposals by October 15. The proposals must detail the associations' plans for the 1994-95 year so the process of deciding block grant allocations for each sport can swing into action. The SDB is also inviting associations to make presentations outlining their past achievements and future goals for a meeting planned in November. SDB sports development manager Margaret Siu said: ''We hope the presentation will help both the associations and us to focus clearly on the future. ''Along with the yearly plan, these presentations will form the basis for deciding block grants.'' Individual block grants will be announced in late January next year. Since 1990, the SDB's funding of associations has increased from $19.2 million to $36.29 million in the current year. The number of SDB-funded staff working in associations has also increased from 55 to 73. In another development, associations have been given a chance to look at their future homes by means of a model office. The SDB have set up a mock-up of the offices that will be available to associations at So Kon Po's $80 million Sports House, which will be opened in April 1994. More than 30 associations have said they will move to Sports House, which will be rent-free. The mock-up office was set up in a vacant room at the SDB headquarters in Causeway Bay. SDB director of development services, Mick Aitken, said: ''We took a group of people to see Sports House. They got an idea of what it was like outside but could not get an idea of what it would be like inside. ''So since we had a vacant room, we decided to set up a model office so people could see what they are moving into.''
