EN I�LL� Re uest #or Quate: Valentine Lake Subwatershed Drainaqe.Studv The City of Arde� Hills is seeking quotes co co�nplete a dra�raage study of the Valentine Lake subwatershed surrounding Vaientine Park. Project Understanding The City of Arden Hilts is looking to defne and anderstand the �ydrology that reaches Valentine P�-k. Valentine Park is located on the southwest corner of Valentine Lake Road and Old Highway 10, across the street from Lake Valentine. A location map is attached. The park current�y has a baseba]] field, a play structure and a p�ved parking ]ot. A warrnir�g house was located ac the park, but was recently moved. 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. The residential neighborhoc�d just west of Valentine Park also has a storm sewer system that drains directly into the west pan af the park, and then tIows through a ditch around the south side of the park. Both of Ehese systems drain toward the northeast eorner of the park, where they discharge iRto Valentine Lake via c�lverts under Old Highway ] 0. The purpose of this study rs to evaluate existing conditions and develop a plan to reduce flooding in Va]entine Park_ This plan wi1l be implemented as projects arise. Future projects in the 10-year Capita] Improvement Plan include the reeoastruction of two neighborhoods (north and south of Lake Valentine Roari) and improvements to Valentine Fark. After the data is collectec� aad mode] is created, the consuItant will evaluate possible solutions, associated costs and present the information iR a sunnmary report.
