Title

Boulevard Drive Storm Drain Improvements

Description

The Project involves the construction of an approximately 200-foot-long storm drain box culvert within Boulevard Drive, 69th Street, and a portion of the Kroc Center parking lot. The new storm drain facility would extend from an existing box culvert within Boulevard Drive and connect to an existing downstream box culvert within the Kroc Center parking lot. The new storm drain would divert high flows that exceed the capacity of the existing off-site channel adjacent to the south through the proposed box culvert. The storm drain facility would consist of either a single 14-foot by 4-foot, double 8-foot by 4-foot, or similar box culvert of adequate size to mitigate roadway and assoiated flooding beneath the roadways and parking lot. It would be constructed via open trench construction within the roadway (see Figure 3, Project Site Plan). Existing utilities would be relocated by the utility owners in order to accommodate the new storm drain infrastructure. Following construction, Boulevard Drive and the disturbed portions of the Kroc Center parking lot would be repaved. Project construction would be completed in approximately one year, including utility relocations prior to excavation. Construction phases would consist of utility relocations, excavation of the trench, and concrete pouring work. Approximately 1,000 cubic yards of excavation material is required to dig the trench, which would be approximately 15 feet wide by 10 feet deep.
