In　order　to　control　stormwater　runoff　and　reduce　water　pollution,　stormwater　management　planning　was　carried　out　in　Futian　River　watershed　of　Shenzhen　city,　China.　Major　rain　harvesting　methods　for　different　land　use,　including　roof　rainwater　collection,　road　rainwater　collection　and　green　space　rainwater　infiltration　were　investigated.　Respective　harvesting　methods　in　mountain　areas　and　urban　areas　were　conducted.　The　instantaneous　unit　hydrograph　(IUH)　method　and　the　EPA　Storm　Water　Management　Model　(SWMM)　were　recommended　for　flow　routing　in　mountain　areas　and　urban　areas.　The　runoff　coefficient　of　Futian　River　watershed　reduces　from　0.6　to　0.52　after　stormwater　management.　The　result　shows　Futian　River　watershed　has　great　potential　in　rain　harvesting.　The　planning　practice　has　a　significant　effect　on　runoff　reduction.　This　case　of　stormwater　utilization　planning　provides　useful　information　to　stormwater　managers　and　site　designers,　and　can　serve　as　example　for　other　cities　with　similar　situation.
