In the spring, the park is prone to floading, which has deIayed plans for future park irr3provements_ The Consultant wil] develop an XA-SWMM model to determine the vo]�me oF water reaching the par�C and identifying poten�ial solutions to alleviate flooding in ihe park. Valentine Lake Road has an exEensive s[orm sewer system that was built in ] 995, whieh inc)udes a grit chamber at the corner c�f Valentine Lake Road and O�d Highway 30.
