Residential developments with a gross aggregate area of three acres or more, where 50% or more of the area is impervious surfaces, i.e., roads, building, parking facilities and other improvements.
(4) 
Developments which, in the opinion of the Town Engineer, will exceed the safe capacity of the existing drainage facilities, or the receiving water body, or will cause erosion or water pollution, or will otherwise endanger downstream property owners of their property. "Safe capacity" is defined as the rate of flow that can be handled without the potential for flooding damages.
B. 
In the case of phased development, or where there is the potential for phased development, the gross aggregate area shall be defined as the entire developable parcel under the ownership of the developer.
C. 
Developments subject to on-site detention and runoff control provisions shall provide on-site storage to safely accommodate runoff from the site in its developed condition for a 100-year intensity rainfall event of any duration, while utilizing a peak discharge rate from the site which does not exceed the peak runoff rate from the site for the two-year and five-year intensity rainfall event which would have occurred with the site in its undeveloped condition.
D. 
Stormwater computations shall be submitted utilizing Technical Release No. 55, Urban Hydrology for Small Watersheds, prepared by USDA Soil Conservation Service, or other approved procedures. The analysis shall contain inflow and outflow hydrographs, basin routing and time/elevation graphs for both the ten-year and 100-year event.
