Low-impact　development　(LID)　is　generally　regarded　as　an　effective　solution　for　urban　stormwater　management.　However,　the　effects　of　LID　on　storm　flooding　on　an　urban　drainage　systems　scale　have　not　been　fully　understood　under　different　rainfall　characteristics.　In　this　paper,　using　a　high-density　residential　catchment　in　China　as　a　case　study,　the　PCSWMM　model　is　applied　to　simulate　the　control　effects　of　seven　LID　land　layout　scenarios　on　water　quantity　and　quality　of　rainfall　runoff　under　different　rainfall　return　periods,　durations,　and　locations　of　peak　rainfall　intensity.　The　simulations　indicated　the　following　results:　(1)　All　seven　LID　scenarios　are　more　effective　in　flood　control　during　smaller　rainfall　return　periods　and　longer　rainfall　duration　storms,　and　the　influence　of　locations　of　peak　rainfall　intensity　on　the　rainfall　runoff　is　not　obvious.　(2)　Permeable　pavement　is　the　best　choice　in　single　LID　measures,　and　the　combination　of　permeable　pavement,　vegetative　swale,　and　a　green　roof　is　the　best　choice　among　combined　LID　layouts.　This　paper　gives　insight　into　the　performance　of　LID　designs　under　different　rainfall　characteristics,　which　is　essential　for　effective　sponge　city　construction.
