BACKGROUND INFORMATION:
In recent years, the City experienced a number of historic rain events that exceeded the design capacities of drainage facilities. Kofu Park is a dual use basin that contains a baseball diamond and skatepark while serving as a storm water detention basin during rainfall events. The baseball diamond and skatepark are separated by a berm / walkway that operationally divides the park into two basins. The north basin contains the baseball diamond and the south basin contains the skatepark (Exhibit A).
The current design allows storm water to enter the north basin during most rainfall events. This operational approach protects the skate park equipment by keeping the south basin dry until the north basin reaches 1' above its design high water elevation. While this approach protects the skatepark equipment, the full basin capacity is not utilized and there are negative consequences. Once the water surface elevation is more than 1' above the design high water elevation of the baseball field, it has already begun flooding Ham Lane and the City's Municipal Services Center parking lot.
This project will install a 24" culvert between the baseball diamond and skatepark so water will passively flow into ...
