| Abstract |
Ihe purpose of this study is to evaluate the effects the storage type of permeable concrete block paving (ST-PCBP) have on runoff reduction and infiltration increasement at Andong Maskdance Festival Square. This was accomplished using the NRCS-curve number method over the last 10 years. Two different scenarios were developed in this study for low impact development (LID) design. For the 1st scenario, the walking path and parking lot were install using the ST-PCBP and runoff from the inline skating rink (3,808 m2) and lawn (11,191 m2) were routed to the ST-PCBP, but the rooftop runoff flowed into the storm water drainage system. For the 2nd scenario, one of the non-structural BMPs, disconnected impervious surface (DIS), was applied so additional runoff from rooftop would enter the ST-PCBP. It was determined that ST-PCBP could significantly reduce surface runoff from the study area and increase infiltration with 71% and 88% of surface runoff reduction and 151% and 215% of infiltration increasement for scenarios 1 and 2, respectively. The effect of LID in the 2nd scenario was better than the 1st scenario, therefore DIS in conjunction with ST-PCBP could be a more cost-effective LID application. |
